2,775 | <p>Here's what I use:</p>
<pre><code>SELECT CAST(FLOOR(CAST(getdate() as FLOAT)) as DATETIME)
</code></pre>
<p>I'm thinking there may be a better and more elegant way.</p>
<p>Requirements:</p>
<ul>
<li>It has to be as fast as possible (the less casting, the better).</li>
<li>The final result has to be a <code>datetime</code> type, not a string.</li>
</ul>

2,780 | <p>Let's say that we have an ARGB color:</p>
<pre><code>Color argb = Color.FromARGB(127, 69, 12, 255); //Light Urple.
</code></pre>
<p>When this is painted on top of an existing color, the colors will blend. So when it is blended with white, the resulting color is <code>Color.FromARGB(255, 162, 133, 255);</code></p>
<p>The solution should work like this:</p>
<pre><code>Color blend = Color.White;
Color argb = Color.FromARGB(127, 69, 12, 255); //Light Urple.
Color rgb = ToRGB(argb, blend); //Same as Color.FromARGB(255, 162, 133, 255);
</code></pre>
<p>What is <code>ToRGB</code>'s implementation? </p>

2,785 | <p>Should you set all the objects to <code>null</code> (<code>Nothing</code> in VB.NET) once you have finished with them? </p>
<p>I understand that in .NET it is essential to dispose of any instances of objects that implement the <code>IDisposable</code> interface to release some resources although the object can still be something after it is disposed (hence the <code>isDisposed</code> property in forms), so I assume it can still reside in memory or at least in part?</p>
<p>I also know that when an object goes out of scope it is then marked for collection ready for the next pass of the garbage collector (although this may take time).</p>
<p>So with this in mind will setting it to <code>null</code> speed up the system releasing the memory as it does not have to work out that it is no longer in scope and are they any bad side effects?</p>
<p>MSDN articles never do this in examples and currently I do this as I cannot
see the harm. However I have come across a mixture of opinions so any comments are useful.</p>

2,804 | <p>I have an application that displays an image inside of a Windows Forms <code>PictureBox</code> control. The <code>SizeMode</code> of the control is set to <code>Zoom</code> so that the image contained in the <code>PictureBox</code> will be displayed in an aspect-correct way regardless of the dimensions of the <code>PictureBox</code>.</p>
<p>This is great for the visual appearance of the application because you can size the window however you want and the image will always be displayed using its best fit. Unfortunately, I also need to handle mouse click events on the picture box and need to be able to translate from screen-space coordinates to image-space coordinates.</p>
<p>It looks like it's easy to translate from screen space to control space, but I don't see any obvious way to translate from control space to image space (i.e. the pixel coordinate in the source image that has been scaled in the picture box).</p>
<p>Is there an easy way to do this, or should I just duplicate the scaling math that they're using internally to position the image and do the translation myself?</p>

2,811 | <p>I have a table with a structure like the following:</p>

<pre><code><root>

<clientID>54321</clientID>
</root>
</code></pre>
<p>The best I've been able to do so far was getting it like this:</p>
<pre><code><root clientID="10705"/>

<p>I'm using this SQL statement:</p>
<pre><code>SELECT
1 as tag,
null as parent,
AccountNumber as 'root!1!clientID'
FROM
Location.LocationMDAccount
WHERE
locationid = 'long-guid-here'

<p>So far, I've looked at the documentation on <a href="http://msdn.microsoft.com/en-us/library/ms345137.aspx" rel="nofollow noreferrer">the MSDN page</a>, but I've not come out with the desired results.</p>

2,840 | <p>How do I page results in SQL Server 2005?</p>

<p>What I mean by paging is, for example, if I list users by their username, I want to be able to only return the first 10 records, then the next 10 records and so on.</p>

2,871 | <p>What would be the best way to fill a C# struct from a byte[] array where the data was from a C/C++ struct? The C struct would look something like this (my C is very rusty):</p>
<pre><code>typedef OldStuff {
CHAR Name[8];
UInt32 User;
CHAR Location[8];
UInt32 TimeStamp;
UInt32 Sequence;
CHAR Tracking[16];
CHAR Filler[12];
}
</code></pre>
<p>And would fill something like this:</p>
<pre><code>[StructLayout(LayoutKind.Explicit, Size = 56, Pack = 1)]
public struct NewStuff
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
[FieldOffset(0)]
public string Name;
[MarshalAs(UnmanagedType.U4)]
[FieldOffset(8)]
public uint User;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
[FieldOffset(12)]
public string Location;
[MarshalAs(UnmanagedType.U4)]
[FieldOffset(20)]
public uint TimeStamp;
[MarshalAs(UnmanagedType.U4)]
[FieldOffset(24)]
public uint Sequence;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 16)]
[FieldOffset(28)]
public string Tracking;
}
</code></pre>
<p>What is best way to copy <code>OldStuff</code> to <code>NewStuff</code>, if <code>OldStuff</code> was passed as byte[] array?</p>
<p>I'm currently doing something like the following, but it feels kind of clunky.</p>
<pre><code>GCHandle handle;
NewStuff MyStuff;
int BufferSize = Marshal.SizeOf(typeof(NewStuff));
byte[] buff = new byte[BufferSize];
Array.Copy(SomeByteArray, 0, buff, 0, BufferSize);
handle = GCHandle.Alloc(buff, GCHandleType.Pinned);
MyStuff = (NewStuff)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(NewStuff));
handle.Free();
</code></pre>
<p>Is there better way to accomplish this?</p>
<hr>
<p>Would using the <code>BinaryReader</code> class offer any performance gains over pinning the memory and using <code>Marshal.PtrStructure</code>?</p>

2,874 | <p>I have a control that is modelled on a <strong>ComboBox</strong>. I want to render the control so that the control <strong>border</strong> looks like that of a standard <strong>Windows ComboBox</strong>. Specifically, I have followed the MSDN documentation and all the rendering of the control is correct except for rendering when the control is disabled.</p>
<p>Just to be clear, this is for a system with <strong>Visual Styles</strong> enabled. Also, all parts of the control render properly except the border around a disabled control, which does not match the disabled <strong>ComboBox border</strong> colour.</p>
<p>I am using the <strong>VisualStyleRenderer</strong> class. MSDN suggests using the <code>VisualStyleElement.TextBox</code> element for the <strong>TextBox</strong> part of the <strong>ComboBox</strong> control but a standard disabled <strong>TextBox</strong> and a standard disabled <strong>ComboBox</strong> draw slightly differently (one has a light grey border, the other a light blue border).</p>
<p>How can I get correct rendering of the control in a disabled state?</p>

<p>I have been searching the net for any solutions, and most seem to be related to too many MySQL connections or that the user I am logging into MySQL as does not have permission. I have checked both. I can still perform my other queries elsewhere in the software, and I have verified that the account has the correct permissions.</p>

<p>Specifically, I want to write tests for code that retrieve records from the database, but the answers will depend on the data in the database (which may change over time).</p>
<p>Do people usually make a separate development system with a 'frozen' database so that any given function should always return the exact same result set?</p>

</code></pre>
<p>If I do <code>nslookup 10.26.6.12</code> then I get the correct reverse DNS so
that shows that my machine is seeing the DNS server.</p>
<p>I have tried <code>Socket.gethostbyname</code>, <code>gethostbyaddr</code>, but it doesn't work.</p>
<p>Any guidance will be much appreciated.</p>

3,021 | <p>One of the topics that seems to come up regularly on mailing lists and online discussions is the merits (or lack thereof) of doing a Computer Science Degree. An argument that seems to come up time and again for the negative party is that they have been coding for some number of years and they have never used recursion.</p>
<p>So the question is:</p>
<ol>
<li>What is recursion?</li>
<li>When would I use recursion?</li>
<li>Why don't people use recursion?</li>

3,088 | <p><strong>Original Question</strong></p>
<p>I am currently engaged in teaching my brother to program. He is a total beginner, but very smart. (And he actually wants to learn). I've noticed that some of our sessions have gotten bogged down in minor details, and I don't feel I've been very organized. (<em>But the answers to this post have helped a lot.</em>)</p>
<p>What can I do better to teach him effectively? Is there a logical order that I can use to run through concept by concept? Are there complexities I should avoid till later?</p>
<p>The language we are working with is <a href="http://www.python.org" rel="noreferrer">Python</a>, but advice in any language is welcome.</p>

3,106 | <p>I'm developing some cross platform software targeting Mono under Visual Studio and would like to be able to build the installers for Windows and Linux (Ubuntu specifically) with a single button click. I figure I could do it by calling cygwin from a post-build event, but I was hoping for at best a Visual Studio plugin or at worst a more Windows-native way of doing it. It seems like the package format is fairly simple and this must be a common need.</p>

3,112 | <p>I have a perl variable <code>$results</code> that gets returned from a service. The value is supposed to be an array, and <code>$results</code> should be an array reference. However, when the array has only one item in it, <code>$results</code> will be set to that value, and not a referenced array that contains that one item.</p>
<p>I want to do a <code>foreach</code> loop on the expected array. Without checking <code>ref($results) eq 'ARRAY'</code>, is there any way to have something equivalent to the following:</p>
<pre><code>foreach my $result (@$results) {
# Process $result
}
</code></pre>
<p>That particular code sample will work for the reference, but will complain for the simple scalar.</p>
<p>EDIT: I should clarify that there is no way for me to change what is returned from the service. The problem is that the value will be a scalar when there is only one value and it will be an array reference when there is more than one value.</p>

3,143 | <p>I'm compiling a NAnt project on linux with TeamCity Continuous Integration server. I have been able to generate a test report by running NAnt on mono thru a Command Line Runner but don't have the options of using the report like a NAnt Runner. I'm also using MBUnit for the testing framework.</p>
<p>How can I merge in the test report and display "Tests failed: 1 (1 new), passed: 3049" for the build?</p>
<p><strong>Update:</strong> take a look at MBUnitTask its a NAnt task that uses sends messages that TeamCity expects from NUnit so it lets you use all of TeamCity's features for tests.</p>
<p><a href="http://code.google.com/p/nant-extensions/wiki/MbUnitTask" rel="noreferrer">MBUnitTask</a></p>
<p><strong>Update:</strong> Galio has better support so you just have to reference the Galio MBUnit 3.5 dlls instead of the MBUnit 3.5 dlls and switch to the galio runner to make it work.</p>

3,157 | <p>In an application that heavily relies on <code>.htaccess</code> RewriteRules for its PrettyURLs (CakePHP in my case), how do I correctly set up directives to exclude certain directories from this rewriting? That is:</p>
<pre><code>/appRoot/.htaccess
app/
static/
</code></pre>
<p>By default every request to <code>/appRoot/*</code> is being rewritten to be picked up by <code>app/webroot/index.php</code>, where it's being analysed and corresponding controller actions are being invoked. This is done by these directives in <code>.htaccess</code>:</p>
<pre><code>RewriteBase /appRoot
RewriteRule ^$ app/webroot/ [L]
RewriteRule (.*) app/webroot/$1 [L]
</code></pre>
<p>I now want to exclude a few directories like static/ from this rewriting. I tried with this <em>before</em> the Cake RewriteRules:</p>
<pre><code>RewriteCond $1 ^(static|otherDir).*$ [NC]
RewriteRule (.*) - [L]
</code></pre>
<p>It works in so far that requests are no longer rewritten, but now <strong>all</strong> requests are being skipped, even legitimate Cake requests which should not match <code>^(static|otherDir).*$</code>.</p>
<p>I tried several variations of these rules but can't get it to work the way I want.</p>

3,163 | <p>I have been trying to find a really fast way to parse yyyy-mm-dd [hh:mm:ss] into a Date object. Here are the 3 ways I have tried doing it and the times it takes each method to parse 50,000 date time strings.</p>

<pre><code>castMethod1 takes 3673 ms

}
var year:int = int(dateString.substr(0,4));
var month:int = int(dateString.substr(5,2))-1;
var day:int = int(dateString.substr(8,2));
if ( year == 0 && month == 0 && day == 0 ) {
return null;
}
if ( dateString.length == 10 ) {
return new Date(year, month, day);
}
var hour:int = int(dateString.substr(11,2));
var minute:int = int(dateString.substr(14,2));
var second:int = int(dateString.substr(17,2));
return new Date(year, month, day, hour, minute, second);
}
</code></pre>
<p>-</p>
<pre><code>private function castMethod2(dateString:String):Date {
if ( dateString == null ) {
return null;
}
if ( dateString.indexOf("0000-00-00") != -1 ) {
return null;
}
dateString = dateString.split("-").join("/");
return new Date(Date.parse( dateString ));
}
</code></pre>
<p>-</p>
<pre><code>private function castMethod3(dateString:String):Date {
if ( dateString == null ) {
return null;
}
var mainParts:Array = dateString.split(" ");
var dateParts:Array = mainParts[0].split("-");
if ( Number(dateParts[0])+Number(dateParts[1])+Number(dateParts[2]) == 0 ) {
return null;
}
return new Date( Date.parse( dateParts.join("/")+(mainParts[1]?" "+mainParts[1]:" ") ) );
}
</code></pre>
<hr>
<p>No, Date.parse will not handle dashes by default. And I need to return null for date time strings like <code>"0000-00-00"</code>.</p>

But I also want the web browser to see changes made to these files without requiring the user to clear their browser cache. Also want a solution that works well with a version control system such as Subversion.</p>
<hr />
<blockquote>
<p>Some solutions I have seen involve adding a version number to the end of the file in the form of a query string.</p>
<p>Could use the SVN revision number to automate this for you: <a href="https://stackoverflow.com/questions/2308/aspnet-display-svn-revision-number">ASP.NET Display SVN Revision Number</a></p>
</blockquote>
<p>Can you specify how you include the <a href="http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html" rel="noreferrer">Revision</a> variable of another file? That is in the HTML file I can include the Revision number in the URL to the CSS or Javascript file.</p>
<p>In the <a href="http://svnbook.red-bean.com" rel="noreferrer">Subversion book</a> it says about Revision: "This keyword describes the last known revision in which this file changed in the repository".</p>

<p>Firefox also allows pressing <kbd>CTRL</kbd>+<kbd>R</kbd> to reload everything on a particular page.</p>

<p>To clarify I am looking for solutions that don't require the user to do anything on their part.</p>

3,234 | <p>How would one display any add content from a "dynamic" aspx page? Currently I am working on using the System.Web.HttpResponse "Page.Response" to write a file that is stored on a web server to a web request.</p>
<p>This would allow people to hit a url to the type <a href="http://www.foo.com?Image=test.jpg" rel="noreferrer">http://www.foo.com?Image=test.jpg</a> and have the image display in their browser. So as you may know this revolves around the use of Response.ContentType.</p>
<p>By using </p>
<pre><code>Response.ContentType = "application/octet-stream";
</code></pre>
<p>I am able to display images of type gif/jpeg/png (all i have tested so far), bit trying to display .swf or .ico files gives me a nice little error.</p>
<p>using</p>
<pre><code>Response.ContentType = "application/x-shockwave-flash";
</code></pre>
<p>I can get flash files to play, but then the images are messed.</p>
<p>So how do i <strong>easily</strong> choose the contenttype?</p>

3,260 | <p>We use a data acquisition card to take readings from a device that increases its signal to a peak and then falls back to near the original value. To find the peak value we currently search the array for the highest reading and use the index to determine the timing of the peak value which is used in our calculations.</p>
<p>This works well if the highest value is the peak we are looking for but if the device is not working correctly we can see a second peak which can be higher than the initial peak. We take 10 readings a second from 16 devices over a 90 second period.</p>
<p>My initial thoughts are to cycle through the readings checking to see if the previous and next points are less than the current to find a peak and construct an array of peaks. Maybe we should be looking at a average of a number of points either side of the current position to allow for noise in the system. Is this the best way to proceed or are there better techniques?</p>
<hr>
<p>We do use LabVIEW and I have checked the <a href="http://forums.lavag.org/Peak-Detection-t8499.html" rel="noreferrer">LAVA forums</a> and there are a number of interesting examples. This is part of our test software and we are trying to avoid using too many non-standard VI libraries so I was hoping for feedback on the process/algorithms involved rather than specific code. </p>

3,315 | <p>I need to set the height of every textbox on my form, some of which are nested within other controls. I thought I could do something like this:</p>
<pre><code>private static IEnumerator<TextBox> FindTextBoxes(Control rootControl)
{
foreach (Control control in rootControl.Controls)
{
if (control.Controls.Count > 0)
{
// Recursively search for any TextBoxes within each child control
foreach (TextBox textBox in FindTextBoxes(control))
{
yield return textBox;
}
}
TextBox textBox2 = control as TextBox;
if (textBox2 != null)
{
yield return textBox2;
}
}
}
</code></pre>
<p>Using it like this:</p>
<pre><code>foreach(TextBox textBox in FindTextBoxes(this))
{
textBox.Height = height;
}
</code></pre>
<p>But of course the compiler spits its dummy, because <em>foreach</em> expects an <strong>IEnumerable</strong> rather than an <strong>IEnumerator</strong>.</p>
<p>Is there a way to do this without having to create a separate class with a <strong>GetEnumerator()</strong> method?</p>

3,400 | <p><strong>Note:</strong> I <em>am</em> using SQL's Full-text search capabilities, CONTAINS clauses and all - the * is the wildcard in full-text, % is for LIKE clauses only.</p>
<p>I've read in several places now that "leading wildcard" searches (e.g. using "*overflow" to match "stackoverflow") is not supported in MS SQL. I'm considering using a <a href="http://blogs.msdn.com/sqlclr/archive/2005/06/29/regex.aspx" rel="noreferrer" title="SQL CLR Blog">CLR function to add regex matching</a>, but I'm curious to see what other solutions people might have.</p>
<p><strong>More Info</strong>: <a href="http://msdn.microsoft.com/en-us/library/ms552152.aspx" rel="noreferrer" title="MSDN">You can add the asterisk only at the end of the word or phrase.</a> - along with my empirical experience: When matching "myvalue", "my*" works, but "(asterisk)value" returns no match, when doing a query as simple as:</p>
<pre><code>SELECT * FROM TABLENAME WHERE CONTAINS(TextColumn, '"*searchterm"');
</code></pre>
<p>Thus, my need for a workaround. I'm only using search in my site on an actual search page - so it needs to work basically the same way that Google works (in the eyes on a Joe Sixpack-type user). Not nearly as complicated, but this sort of match really shouldn't fail.</p>

<p>At this time, the Maps API is not
available over a secure (SSL)
connection. If you are running the
Maps API on a secure site, the browser
may warn the user about non-secure
objects on the screen.</p>
</blockquote>
<p>We have considered the following options</p>
<ol>
<li>Splitting the page so that credit card collection (the requirement for SSL) is not on the same page as the Google Map.</li>
<li>Switching to another map provider, such as Virtual Earth. Rumor has it that they support SSL.</li>
<li>Playing tricks with IFRAMEs. Sounds kludgy.</li>
<li>Proxying the calls to Google. Sounds like a lot of overhead.</li>
</ol>
<p>Are there other options, or does anyone have insight into the options that we have considered?</p>

3,486 | <p>I have control over the HttpServer but not over the ApplicationServer or the Java Applications sitting there but I need to block direct access to certain pages on those applications. Precisely, I don't want users automating access to forms issuing direct GET/POST HTTP requests to the appropriate servlet. </p>
<p>So, I decided to block users based on the value of <code>HTTP_REFERER</code>. After all, if the user is navigating inside the site, it will have an appropriate <code>HTTP_REFERER</code>. Well, that was what I thought. </p>
<p>I implemented a rewrite rule in the .htaccess file that says: </p>
<pre><code>RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} !^http://mywebaddress(.cl)?/.* [NC]
RewriteRule (servlet1|servlet2)/.+\?.+ - [F]
</code></pre>
<p>I expected to forbid access to users that didn't navigate the site but issue direct GET requests to the "servlet1" or "servlet2" servlets using querystrings. But my expectations ended abruptly because the regular expression <code>(servlet1|servlet2)/.+\?.+</code> didn't worked at all. </p>
<p>I was really disappointed when I changed that expression to <code>(servlet1|servlet2)/.+</code> and it worked so well that my users were blocked no matter if they navigated the site or not. </p>
<p>So, my question is: How do I can accomplish this thing of not allowing "robots" with direct access to certain pages if I have no access/privileges/time to modify the application?</p>

3,607 | <p>I've got TotroiseSVN installed and have a majority of my repositories checking in and out from C:\subversion\ <em>and a couple checking in and out from a network share (I forgot about this when I originally posted this question)</em>.</p>
<p>This means that I don't have a "subversion" server per-se.</p>
<p>How do I integrate TortoiseSVN and Fogbugz?</p>

3,682 | <p>I have a MySQL table with approximately 3000 rows per user. One of the columns is a datetime field, which is mutable, so the rows aren't in chronological order.</p>
<p>I'd like to visualize the time distribution in a chart, so I need a number of individual datapoints. 20 datapoints would be enough.</p>
<p>I could do this:</p>
<pre><code>select timefield from entries where uid = ? order by timefield;
</code></pre>
<p>and look at every 150th row.</p>
<p>Or I could do 20 separate queries and use <code>limit 1</code> and <code>offset</code>. </p>
<p>But there must be a more efficient solution...</p>

3,725 | <p>I'm writing an application that is basically just a preferences dialog, much like the tree-view preferences dialog that Visual Studio itself uses. The function of the application is simply a pass-through for data from a serial device to a file. It performs many, many transformations on the data before writing it to the file, so the GUI for the application is simply all the settings that dictate what those transformations should be.</p>
<p>What's the best way to go about designing/coding a tree-view preferences dialog? The way I've been going about it is building the main window with a docked tree control on the left. Then I have been creating container controls that correspond to each node of the tree. When a node is selected, the app brings that node's corresponding container control to the front, moves it to the right position, and maximizes it in the main window. This seems really, really clunky while designing it. It basically means I have tons of container controls beyond the edge of the main window during design time that I have to keep scrolling the main window over to in order to work with them. I don't know if this totally makes sense the way I'm writing this, but maybe this visual for what I'm talking about will make more sense:</p>
<p><img src="https://i.stack.imgur.com/bVRJB.png" alt="form design"></p>
<p>Basically I have to work with this huge form, with container controls all over the place, and then do a bunch of run-time reformatting to make it all work. This seems like a <em>lot</em> of extra work. Am I doing this in a totally stupid way? Is there some "obvious" easier way of doing this that I'm missing?</p>

3,739 | <p>I have an unusual situation in which I need a SharePoint timer job to both have local administrator windows privileges and to have <code>SHAREPOINT\System</code> SharePoint privileges.</p>
<p>I can get the windows privileges by simply configuring the timer service to use an account which is a member of local administrators. I understand that this is not a good solution since it gives SharePoint timer service more rights then it is supposed to have. But it at least allows my SharePoint timer job to run <code>stsadm</code>.</p>
<p>Another problem with running the timer service under local administrator is that this user won't necessarily have <code>SHAREPOINT\System</code> SharePoint privileges which I also need for this SharePoint job. It turns out that <code>SPSecurity.RunWithElevatedPrivileges</code> won't work in this case. Reflector shows that <code>RunWithElevatedPrivileges</code> checks if the current process is <code>owstimer</code> (the service process which runs SharePoint jobs) and performs no elevation this is the case (the rational here, I guess, is that the timer service is supposed to run under <code>NT AUTHORITY\NetworkService</code> windows account which which has <code>SHAREPOINT\System</code> SharePoint privileges, and thus there's no need to elevate privileges for a timer job).</p>
<p>The only possible solution here seems to be to run the timer service under its usual NetworkService windows account and to run stsadm as a local administrator by storing the administrator credentials somewhere and passing them to System.Diagnostics.Process.Run() trough the StarInfo's Username, domain and password.</p>
<p>It seems everything should work now, but here is another problem I'm stuck with at the moment. Stsamd is failing with the following error popup (!) (Winternals filemon shows that stsadm is running under the administrator in this case):</p>
<p><code>The application failed to initialize properly (0x0c0000142).</code> <br />
<code>Click OK to terminate the application.</code></p>
<p>Event Viewer registers nothing except the popup.</p>
<p>The local administrator user is my account and when I just run <code>stsadm</code> interactively under this account everything is ok. It also works fine when I configure the timer service to run under this account.</p>
<p>Any suggestions are appreciated :)</p>

3,798 | <p>Currently I have two Linux servers running MySQL, one sitting on a rack right next to me under a 10 Mbit/s upload pipe (main server) and another some couple of miles away on a 3 Mbit/s upload pipe (mirror).</p>
<p>I want to be able to replicate data on both servers continuously, but have run into several roadblocks. One of them being, under MySQL master/slave configurations, every now and then, some statements drop (!), meaning; some people logging on to the mirror URL don't see data that I know is on the main server and vice versa. Let's say this happens on a meaningful block of data once every month, so I can live with it and assume it's a "lost packet" issue (i.e., god knows, but we'll compensate).</p>
<p>The other most important (and annoying) recurring issue is that, when for some reason we do a major upload or update (or reboot) on one end and have to <a href="http://en.wiktionary.org/wiki/sever" rel="noreferrer">sever</a> the link, then LOAD DATA FROM MASTER doesn't work and I have to manually dump on one end and upload on the other, quite a task nowadays moving some .5 TB worth of data.</p>
<p>Is there software for this? I know MySQL (the "corporation") offers this as a VERY expensive service (full database replication). What do people out there do? The way it's structured, we run an automatic failover where if one server is not up, then the main URL just resolves to the other server. </p>

<p>That's three queries stuck together, kinda sorta. However, the result set that comes back reflects results from query #3 before the results from query #1 which is undesired.</p>
<p>Is there any way to prioritize these so that results come as all for query #1, then all for query #2 then all for query #3? I don't want to do this in PHP just yet (not to mention having to control for results that showed up in the first query not to show in the second and so forth).</p>

3,868 | <p>I'm downloading a web page (tag soup HTML) with XMLHttpRequest and I want to take the output and turn it into a DOM object that I can then run XPATH queries on. How do I convert from a string into DOM object?</p>
<p>It appears that the general solution is to create a hidden iframe and throw the contents of the string into that. There has been <a href="http://starkravingfinkle.org/blog/2007/03/how-to-parse-html-in-mozilla/" rel="nofollow noreferrer">talk</a> of updating <a href="https://developer.mozilla.org/en-US/docs/Web/API/DOMParser" rel="nofollow noreferrer">DOMParser</a> to support text/html but as of Firefox 3.0.1 you still get an <code>NS_ERROR_NOT_IMPLEMENTED</code> if you try.</p>
<p>Is there any option besides using the hidden iframe trick? And if not, what is the best way to do the iframe trick so that your code works outside the context of any currently open tabs (so that closing tabs won't screw up the code, etc)?</p>
<p><a href="http://mxr.mozilla.org/mozilla/source/browser/components/microsummaries/src/nsMicrosummaryService.js#2090" rel="nofollow noreferrer">This</a> is an example of why I'm looking for a solution other than the iframe hack, if I have to write <em>all</em> that code to have a robust solution, then I'd rather keep looking for something else.</p>

3,976 | <p>I have a Prolite LED sign that I like to set up to show scrolling search queries from a apache logs and other fun statistics. The problem is, my G5 does not have a serial port, so I have to use a usb to serial dongle. It shows up as /dev/cu.usbserial and /dev/tty.usbserial . </p>
<p>When i do this everything seems to be hunky-dory:</p>
<pre><code>stty -f /dev/cu.usbserial
speed 9600 baud;
lflags: -icanon -isig -iexten -echo
iflags: -icrnl -ixon -ixany -imaxbel -brkint
oflags: -opost -onlcr -oxtabs
cflags: cs8 -parenb
</code></pre>
<p>Everything also works when I use the <a href="http://www.versiontracker.com/dyn/moreinfo/macosx/24024" rel="noreferrer">serial port tool</a> to talk to it.</p>
<p>If I run this piece of code while the above mentioned serial port tool, everthing also works. But as soon as I disconnect the tool the connection gets lost. </p>
<pre><code>#!/usr/bin/python
import serial
ser = serial.Serial('/dev/cu.usbserial', 9600, timeout=10)
ser.write("<ID01><PA> \r\n")
read_chars = ser.read(20)
print read_chars
ser.close()
</code></pre>
<p>So the question is, what magicks do I need to perform to start talking to the serial port without the serial port tool? Is that a permissions problem? Also, what's the difference between /dev/cu.usbserial and /dev/tty.usbserial?</p>
<hr>
<p>Nope, no serial numbers. The thing is, the problem persists even with sudo-running the python script, and the only thing that makes it go through if I open the connection in the gui tool that I mentioned.</p>

<p>Although it doesn't occur when I'm trying to access HTTPS, I did notice an error in my System Event log - the source is "Schannel" and the content of the message is:</p>
<blockquote>
<p>A fatal error occurred when attempting
to access the SSL server credential
private key. The error code returned
from the cryptographic module is
0x80090016.</p>
</blockquote>
<p>Edit:<br>
<strong>Steps taken so far</strong></p>
<ul>
<li>Created a working HTTPListener in C# that works for HTTP connections (e.g. "<a href="http://localhost:8089/foldername/" rel="noreferrer">http://localhost:8089/foldername/</a>"</li>
<li>Created a certificate using makecert.exe</li>
<li>Added the certificate to be trusted using certmgr.exe</li>
<li>Used Httpcfg.exe to listen for SSL connections on a test port (e.g. 8090)</li>
<li>Added port 8080 to the HTTPListener via listener.Prefixes.Add(<a href="https://localhost:8090/foldername/" rel="noreferrer">https://localhost:8090/foldername/</a>");</li>
<li>tested an HTTP client connection, e.g. (<a href="http://localhost:8089/foldername/" rel="noreferrer">http://localhost:8089/foldername/</a>") in a browser and receive correct return</li>
<li>tested an HTTPS client connection, e.g. (<a href="http://localhost:8090/foldername/" rel="noreferrer">http://localhost:8090/foldername/</a>") in a browser and receive "Data Transfer Interrupted" (in Firefox)</li>
<li>debugging in visual studio shows that the listener callback that receives the requests never gets hit when the HTTPS connection starts - I don't see any place that I could set a breakpoint to catch anything else earlier.</li>
<li>netstat shows that listening ports are open for both HTTPS and HTTP. the HTTPS port does go to TIME_WAIT after a connection is attempted.</li>
<li><strong><a href="http://www.fiddlertool.com/fiddler/" rel="noreferrer">Fiddler</a> and <a href="http://www.ieinspector.com/httpanalyzer/" rel="noreferrer">HTTPAnalyzer</a> don't catch any of the traffic, I guess it doesn't get far enough in the process to show up in those HTTP analysis tools</strong></li>
</ul>
<p><strong>Questions</strong></p>
<ul>
<li>What could the problem be? </li>
<li>Is there a piece of .Net code I am missing (meaning I have to do more in C# other than simply add a prefix to the listener that points to HTTPS, which is what i have done)</li>
<li>Have a missed a configuration step somewhere? </li>
<li>What else might I do to analyze the problem?</li>
<li>Is the error message in the System Event log a sign of the problem? If so how would it be fixed?</li>
</ul>

4,052 | <p>I am trying to enable Full-text indexing in SQL Server 2005 Express. I am running this on my laptop with Vista Ultimate.</p>
<p>I understand that the standard version of SQL Server Express does not have full-text indexing. I have already downloaded and installed "Microsoft SQL Server 2005 Express Edition with Advanced Services Service Pack 2" (<a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=5B5528B9-13E1-4DB9-A3FC-82116D598C3D&displaylang=en" rel="noreferrer">download</a>).</p>
<p>I have also ensured that both the "SQL Server (instance)" and "SQL Server FullText Search (instance)" services are running on the same account which is "Network Service".</p>
<p>I have also selected the option to "Use full-text indexing" in the Database Properties > Files area.</p>
<p>I can run the sql query "SELECT fulltextserviceproperty('IsFulltextInstalled');" and return 1.</p>
<p>The problem I am having is that when I have my table open in design view and select "Manage FullText Index"; the full-text index window displays the message... </p>
<blockquote>
<p>"Creation of the full-text index is not available. Check that you have the correct permissions or that full-text catalogs are defined."</p>

4,072 | <p>I just did a merge using something like:</p>
<pre><code>svn merge -r 67212:67213 https://my.svn.repository/trunk .
</code></pre>
<p>I only had 2 files, one of which is a simple <code>ChangeLog</code>. Rather than just merging my <code>ChangeLog</code> changes, it actually pulled mine plus some previous ones that were not in the destination <code>ChangeLog</code>. I noticed there was a conflict when I executed --dry-run, so I updated <code>ChangeLog</code>, and there was still a conflict (and I saw the conflict when I did the actual merge).</p>
<p>I then later diffed on the file I was merging from:</p>
<pre><code>svn diff -r 67212:67213 ChangeLog
</code></pre>
<p>And I see just the changes I had made, so I know that extra changes didn't get in there somehow. </p>
<p>This makes me worried that merge is not actually just taking what I changed, which is what I would have expected. Can anybody explain what happened?</p>
<p>UPDATE: In response to NilObject:</p>
<p>So, I have 2 files changed, only ChangeLog is relevant, the other merged fine. When I go to my regular trunk checkout, I do the diff command above and see:</p>
<pre><code>Index: ChangeLog
===================================================================

</code></pre>
<p>After my merge of the previous changes, the diff of ChangeLog looks like this:</p>
<pre><code>Index: ChangeLog

<p>Note that the entry that was incorrectly pulled in was not in the file I am merging it to, but yet it was not one of my changes and shouldn't have been merged anyways. It was easy to fix (remove the extra lines that weren't part of my changes), but it still makes me worry about merging automatically in <code>SVN</code>.</p>

4,149 | <p>I have an application that writes information to file. This information is used post-execution to determine pass/failure/correctness of the application. I'd like to be able to read the file as it is being written so that I can do these pass/failure/correctness checks in real time.</p>
<p>I assume it is possible to do this, but what are the gotcha's involved when using Java? If the reading catches up to the writing, will it just wait for more writes up until the file is closed, or will the read throw an exception at this point? If the latter, what do I do then? </p>
<p>My intuition is currently pushing me towards BufferedStreams. Is this the way to go?</p>

<p>This fails with the error:</p>
<pre><code>int cannot be dereferenced

<p>Now, I get that primitives are not reference types (ie, not an Object) and so cannot have methods. However, Java 5 introduced autoboxing and unboxing (a la C#... which I never liked in C#, but that's beside the point). So with autoboxing, I would expect the above to convert myInt to an Integer and then call toString() on that.</p>
<p>Furthermore, I believe C# allows such a call, unless I remember incorrectly. Is this just an unfortunate shortcoming of Java's autoboxing/unboxing specification, or is there a good reason for this?</p>

<p>In short, I need to keep track of a relatively small number of values (usually a value of 1, and in rare cases more than 1) in a sea of zeros in the matrix (multidimensional array). </p>
<p>A sparse array allows the user to store a small number of values, and assume all undefined records to be a preset value. Since it is not physically possibly to store all values in memory, I need to store only the few non-zero elements. This could be several million entries.</p>
<p>Speed is a huge priority, and I would also like to dynamically choose the number of variables in the class at runtime.</p>
<p>I currently work on a system that uses a binary search tree (b-tree) to store entries. Does anyone know of a better system?</p>

4,369 | <p>I have a directory structure like the following;</p>
<blockquote>
<p>script.php</p>
<p>inc/include1.php<br/>
inc/include2.php</p>
<p>objects/object1.php<br/>
objects/object2.php</p>
<p>soap/soap.php</p>
</blockquote>
<p>Now, I use those objects in both <code>script.php</code> and <code>/soap/soap.php</code>, I could move them, but I want the directory structure like that for a specific reason. When executing <code>script.php</code> the include path is <code>inc/include.php</code> and when executing <code>/soap/soap.php</code> it's <code>../inc</code>, absolute paths work, <code>/mnt/webdev/[project name]/inc/include1.php...</code> But it's an ugly solution if I ever want to move the directory to a different location.</p>
<p>So is there a way to use relative paths, or a way to programmatically generate the <code>"/mnt/webdev/[project name]/"</code>?</p>

4,393 | <p>How can I drop all tables whose names begin with a given string? </p>
<p>I think this can be done with some dynamic SQL and the <code>INFORMATION_SCHEMA</code> tables.</p>

4,416 | <p>I am walking through the MS Press Windows Workflow Step-by-Step book and in chapter 8 it mentions a tool with the filename "wca.exe". This is supposed to be able to generate workflow communication helper classes based on an interface you provide it. I can't find that file. I thought it would be in the latest .NET 3.5 SDK, but I just downloaded and fully installed, and it's not there. Also, some MSDN forum posts had links posted that just go to 404s. So, where can I find wca.exe?</p>
