30,319 | <p>Is there a tag in HTML that will only display its content if JavaScript is enabled? I know <code><noscript></code> works the opposite way around, displaying its HTML content when JavaScript is turned off. But I would like to only display a form on a site if JavaScript is available, telling them why they can't use the form if they don't have it.</p>
<p>The only way I know how to do this is with the <code>document.write();</code> method in a script tag, and it seems a bit messy for large amounts of HTML.</p>

30,321 | <p>I am looking for a method of storing Application Messages, such as</p>
<ul>
<li>"You have logged in successfully"</li>
<li>"An error has occurred, please call the helpdesk on x100"</li>
<li>"You do not have the authority to reset all system passwords" etc</li>
</ul>
<p>So that "when" the users decide they don't like the wording of messages I don't have to change the source code, recompile then redeploy - instead I just change the message store.</p>
<p>I really like the way that I can easily access strings in the web.config using keys and values.</p>
<pre><code>ConfigurationManager.AppSettings("LOGINSUCCESS");
</code></pre>
<p>However as I could have a large number of application messages I didn't want to use the web.config directly. I was going to add a 2nd web config file and use that but of course you can only have one per virtual directory.</p>
<p>Does anyone have any suggestions on how to do this without writing much custom code?</p>

30,354 | <p>In one of my VB6 forms, I create several other Form objects and store them in member variables.</p>
<pre><code>Private m_frm1 as MyForm
Private m_frm2 as MyForm
// Later...
Set m_frm1 = New MyForm
Set m_frm2 = New MyForm
</code></pre>
<p>I notice that I'm leaking memory whenever this (parent) form is created and destroyed. Is it necessary for me to assign these member variables to <code>Nothing</code> in <code>Form_Unload()</code>?</p>
<p>In general, when is that required?</p>
<p>SOLVED: This particular memory leak was fixed when I did an <code>Unload</code> on the forms in question, not when I set the form to <code>Nothing</code>. I managed to remove a few other memory leaks by explicitly setting some instances of Class Modules to <code>Nothing</code>, as well.</p>

30,373 | <p>I remember first learning about vectors in the STL and after some time, I wanted to use a vector of bools for one of my projects. After seeing some strange behavior and doing some research, I learned that <a href="http://www.informit.com/guides/content.aspx?g=cplusplus&seqNum=98" rel="noreferrer">a vector of bools is not really a vector of bools</a>.</p>
<p>Are there any other common pitfalls to avoid in C++?</p>

30,397 | <p>I am trying to set up dynamic per-item menus (Edit Control Block) in SharePoint 2007. My goal is to have certain features that are available based on the current user's group membership.</p>
<p>I know that the CustomAction tag that controls the creation of this menu item has a Rights attribute. The problem that I have with this is that the groups I am using have identical rights in the site (ViewListItems, ManageAlerts, etc). The groups that we have set up deal more with function, such as Manager, Employee, etc. We want to be able to assign a custom feature to a group, and have the menu items associated with that feature visible only to members of that group. Everyone has the same basic site permissions, but will have extra options availble based on their login credentials.</p>
<p>I have seen several articles on modifying the Core.js file to hide items in the context menu, but they are an all-or-nothing approach. There is an interesting post at <a href="http://blog.thekid.me.uk/archive/2008/04/29/sharepoint-custom-actions-in-a-list-view-webpart.aspx" rel="noreferrer">http://blog.thekid.me.uk/archive/2008/04/29/sharepoint-custom-actions-in-a-list-view-webpart.aspx</a> that shows how to dynamically modify the Actions menu. It is trivial to modify this example to check the users group and show or hide the menu based on membership. Unfortunately, this example does not seem to apply to context menu items as evidenced here <a href="http://forums.msdn.microsoft.com/en-US/sharepointdevelopment/thread/c2259839-24c4-4a7e-83e5-3925cdd17c44/" rel="noreferrer">http://forums.msdn.microsoft.com/en-US/sharepointdevelopment/thread/c2259839-24c4-4a7e-83e5-3925cdd17c44/</a>.</p>
<p>Does anyone know of a way to do this without using javascript? If not, what is the best way to check the user's group from javascript?</p>

30,505 | <p>I frequently work with multiple instances of Visual Studio, often working on different branches of the same solution.</p>
<p><a href="https://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B#Strictly_32-bit_versions" rel="noreferrer">Visual C++ 6.0</a> used to display the full path of the current source file in its title bar, but Visual Studio 2005 doesn't appear to do this. This makes it slightly more awkward than it should be to work out which branch of the solution I'm currently looking at (the quickest way I know of is to hover over a tab so you get the source file's path as a tooltip).</p>
<p>Is there a way to get the full solution or file path into the title bar, or at least somewhere that's always visible, so I can quickly tell which branch is loaded into each instance?</p>

30,529 | <p>How could i implement Type-Safe Enumerations in Delphi in a COM scenario ? Basically, i'd like to replace a set of primitive constants of a enumeration with a set of static final object references encapsulated in a class ? .
In Java, we can do something like:</p>
<pre><code>public final class Enum
{
public static final Enum ENUMITEM1 = new Enum ();
public static final Enum ENUMITEM2 = new Enum ();
//...
private Enum () {}
}
</code></pre>
<p>and make comparisons using the customized enumeration type:</p>
<pre><code>if (anObject != Enum.ENUMITEM1) ...
</code></pre>
<p>I am currently using the old Delphi 5 and i would like to declare some enums parameters on the interfaces, not allowing that client objects to pass integers (or long) types in the place of the required enumeration type.
Do you have a better way of implementing enums other than using the native delphi enums ? </p>

30,539 | <p>I'm looking for a good way to enumerate all the Video codecs on a Windows XP/Vista machine.</p>
<p>I need present the user with a set of video codecs, including the compressors and decompressors. The output would look something like</p>
<pre>
Available Decoders
DiVX Version 6.0
XVID
Motion JPEG
CompanyX's MPEG-2 Decoder
Windows Media Video
**Available Encoders**
DiVX Version 6.0
Windows Media Video
</pre>
<p>The problem that I am running into is that there is no reliable way to to capture all of the decoders available to the system. For instance:</p>
<ol>
<li>You can enumerate all the decompressors using DirectShow, but this tells you nothing about the compressors (encoders).</li>
<li>You can enumerate all the Video For Windows components, but you get no indication if these are encoders or decoders.</li>
<li>There are DirectShow filters that may do the job for you perfectly well (Motion JPEG filter for example), but there is no indication that a particular DirectShow filter is a "video decoder".</li>
</ol>
<p>Has anyone found a generalizes solution for this problem using any of the Windows APIs? Does the Windows Vista <a href="http://en.wikipedia.org/wiki/Media_Foundation" rel="nofollow noreferrer">Media Foundation API</a> solve any of these issues?</p>

However that field can be part of group a or b
In the end I need to have all of the items summed for group a and group b</p>
<p>when I say grouped I mean there is a LEFT OUTER JOIN to another table the previous table has a type for the items and the one being joined has a group assigned for this item type</p>
<p>Sorry guys Im a little new to sql I am going to try out what you have given me an get back to you</p>
<p>Ok I feel like we are getting close just not yet allain's I can get them to separate but the issue I need to have both groups to sum on the same row which is difficult because I also have several LEFT OUTER JOIN's involved</p>
<p>Tyler's looks like it might work too so I am trying to hash that out real fast</p>
<p>Alain's seems to be the way to go but I have to tweek it a little more</p>

30,571 | <p>In Maven, dependencies are usually set up like this:</p>
<pre class="lang-xml prettyprint-override"><code><dependency>
<groupId>wonderful-inc</groupId>
<artifactId>dream-library</artifactId>
<version>1.2.3</version>
</dependency>
</code></pre>
<p>Now, if you are working with libraries that have frequent releases, constantly updating the <version> tag can be somewhat annoying. Is there any way to tell Maven to always use the latest available version (from the repository)? </p>

<p>If so, is there a preferred flavor of CruiseControl (CruiseControl.rb or just regular CruiseControl) that would be easier to do this with. </p>
<p>I currently have a Ruby rake file that has steps for doing building and running tests, and wanted to automate this process after doing a checkin. </p>
<p>Also, does CruiseControl have support for git? I couldn't find anything on the website for this.</p>

30,627 | <p>I'm looking for the best method to parse various XML documents using a Java application. I'm currently doing this with SAX and a custom content handler and it works great - zippy and stable. </p>
<p>I've decided to explore the option having the same program, that currently recieves a single format XML document, receive two additional XML document formats, with various XML element changes. I was hoping to just swap out the ContentHandler with an appropriate one based on the first "startElement" in the document... but, uh-duh, the ContentHandler is set and <strong>then</strong> the document is parsed!</p>
<pre><code>... constructor ...
{
SAXParserFactory spf = SAXParserFactory.newInstance();
try {
SAXParser sp = spf.newSAXParser();
parser = sp.getXMLReader();
parser.setErrorHandler(new MyErrorHandler());
} catch (Exception e) {}
... parse StringBuffer ...
try {
parser.setContentHandler(pP);
parser.parse(new InputSource(new StringReader(xml.toString())));
return true;
} catch (IOException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
}
...
</code></pre>
<p>So, it doesn't appear that I can do this in the way I initially thought I could.</p>
<p>That being said, am I looking at this entirely wrong? What is the best method to parse multiple, discrete XML documents with the same XML handling code? <a href="https://stackoverflow.com/questions/23106/best-method-to-parse-various-custom-xml-documents-in-java">I tried to ask in a more general post earlier... but, I think I was being too vague</a>. For speed and efficiency purposes I never really looked at DOM because these XML documents are fairly large and the system receives about 1200 every few minutes. It's just a one way send of information</p>
<p>To make this question too long and add to my confusion; following is a mockup of some various XML documents that I would like to have a single SAX, StAX, or ?? parser cleanly deal with. </p>
<p>products.xml:</p>
<pre><code><products>
<product>
<id>1</id>
<name>Foo</name>
<product>
<id>2</id>
<name>bar</name>
</product>
</products>

30,660 | <p>I'm running a master-slave MySQL binary log replication system (phew!) that, for some data, is not in sync (meaning, the master holds more data than the slave). But the slave stops very frequently on the slightest MySQL error, can this be disabled? (perhaps a my.cnf setting for the replicating slave ignore-replicating-errors or some of the sort ;) )</p>
<p>This is what happens, every now and then, when the slave tries to replicate an item that does not exist, the slave just dies. a quick check at <strong>SHOW SLAVE STATUS \G;</strong> gives</p>
<pre><code> Slave-IO-Running: Yes
Slave-SQL-Running: No
Replicate-Do-DB:
Last-Errno: 1062
Last-Error: Error 'Duplicate entry '15218' for key 1' on query. Default database: 'db'. Query: 'INSERT INTO db.table ( FIELDS ) VALUES ( VALUES )'
</code></pre>
<p>which I promptly fix (once I realize that the slave has been stopped) by doing the following:</p>
<pre><code>STOP SLAVE;
RESET SLAVE;
START SLAVE;
</code></pre>
<p>... lately this has been getting kind of tiresome, and before I spit out some sort of PHP which does this for me, i was wondering if there's some my.cnf entry which will not kill the slave on the first error.</p>
<p>Cheers,</p>

30,729 | <p>I want to create a simple http proxy server that does some very basic processing on the http headers (i.e. if header x == y, do z). The server may need to support hundreds of users. I can write the server in C# (pretty easy) or c++ (much harder). However, would a C# version have as good of performance as a C++ version? If not, would the difference in performance be big enough that it would not make sense to write it in C#?</p>

30,754 | <p>Reading <a href="https://stackoverflow.com/questions/437/what-is-your-solution-to-the-fizzbuzz-problem">this question</a> I found this as (note the quotation marks) "code" to solve the problem (that's perl by the way). </p>
<pre><code>100,{)..3%!'Fizz'*\5%!'Buzz'*+\or}%n*
</code></pre>
<p>Obviously this is an intellectual example without real (I hope to never see that in real code in my life) implications but, when you have to make the choice, when do you sacrifice code readability for performance? Do you apply just common sense, do you do it always as a last resort? What are your strategies?</p>
<p>Edit: I'm sorry, seeing the answers I might have expressed the question badly (English is not my native language). I don't mean performance vs readability only <strong>after</strong> you've written the code, I ask about before you write it as well. Sometimes you can foresee a performance improvement in the future by making some darker design or providing with some properties that will make your class darker. You may decide you will use multiple threads or just a single one because you expect the scalability that such threads may give you, even when that will make the code much more difficult to understand.</p>

30,928 | <p>[We have a Windows Forms database front-end application that, among other things, can be used as a CMS; clients create the structure, fill it, and then use a ASP.NET WebForms-based site to present the results to publicly on the Web. For added flexibility, they are sometimes forced to input actual HTML markup right into a text field, which then ends up as a varchar in the database. This works, but it's far from user-friendly.]</p>
<p>As such… some clients want a WYSIWYG editor for HTML. I'd like to convince them that they'd benefit from using simpler language (namely, Markdown). Ideally, what I'd like to have is a WYSIWYG editor for that. They don't need tables, or anything sophisticated like that.</p>
<p>A cursory search reveals <a href="http://aspnetresources.com/blog/markdown_announced.aspx" rel="noreferrer">a .NET Markdown to HTML converter</a>, and then we have <a href="http://www.codeproject.com/KB/edit/editor_in_windows_forms.aspx" rel="noreferrer">a Windows Forms-based text editor that outputs HTML</a>, but apparently nothing that brings the two together. As a result, we'd still have our varchars with markup in there, but at least it would be both quite human-readable and still easily parseable.</p>
<p>Would this — a WYSIWYG editor that outputs Markdown, which is then later on parsed into HTML in ASP.NET — be feasible? Any alternative suggestions?</p>

30,985 | <p>I recently had to solve this problem and find I've needed this info many times in the past so I thought I would post it. Assuming the following table def, how would you write a query to find all differences between the two?</p>
<p>table def:</p>
<pre><code>CREATE TABLE feed_tbl
(
code varchar(15),
name varchar(40),
status char(1),
update char(1)
CONSTRAINT feed_tbl_PK PRIMARY KEY (code)
CREATE TABLE data_tbl
(
code varchar(15),
name varchar(40),
status char(1),
update char(1)
CONSTRAINT data_tbl_PK PRIMARY KEY (code)
</code></pre>
<p>Here is my solution, as a view using three queries joined by unions. The <code>diff_type</code> specified is how the record needs updated: deleted from <code>_data(2)</code>, updated in <code>_data(1)</code>, or added to <code>_data(0)</code></p>
<pre><code>CREATE VIEW delta_vw AS (
SELECT feed_tbl.code, feed_tbl.name, feed_tbl.status, feed_tbl.update, 0 as diff_type
FROM feed_tbl LEFT OUTER JOIN
data_tbl ON feed_tbl.code = data_tbl.code
WHERE (data_tbl.code IS NULL)
UNION
SELECT feed_tbl.code, feed_tbl.name, feed_tbl.status, feed_tbl.update, 1 as diff_type
FROM data_tbl RIGHT OUTER JOIN
feed_tbl ON data_tbl.code = feed_tbl.code
where (feed_tbl.name <> data_tbl.name) OR
(data_tbl.status <> feed_tbl.status) OR
(data_tbl.update <> feed_tbl.update)
UNION
SELECT data_tbl.code, data_tbl.name, data_tbl.status, data_tbl.update, 2 as diff_type
FROM feed_tbl LEFT OUTER JOIN
data_tbl ON data_tbl.code = feed_tbl.code
WHERE (feed_tbl.code IS NULL)
)
</code></pre>

30,998 | <p>I like to use static functions in C++ as a way to categorize them, like C# does.</p>
<pre><code>Console::WriteLine("hello")

<p>Is this good or bad? If the functions are used often I guess it doesn't matter, but if not do they put pressure on memory?</p>

31,059 | <p>In VS .NET, when you are selecting a folder for a project, a dialog that looks like an OpenFileDialog or SaveFileDialog is displayed, but is set up to accept only folders. Ever since I've seen this I've wanted to know how it's done. I am aware of the FolderBrowserDialog, but I've never really liked that dialog. It starts too small and doesn't let me take advantage of being able to type a path.</p>
<p>I'm almost certain by now there's not a way to do this from .NET, but I'm just as curious how you do it from unmanaged code as well. Short of completely reimplementing the dialog from scratch, how do you modify the dialog to have this behavior?</p>
<p>I'd also like to restate that I am aware of the FolderBrowserDialog but sometimes I don't like to use it, in addition to being genuinely curious how to configure a dialog in this manner. Telling me to just use the FolderBrowserDialog helps me maintain a consistent UI experience but doesn't satisfy my curiosity so it won't count as an answer.</p>
<p>It's not a Vista-specific thing either; I've been seeing this dialog since VS .NET 2003, so it is doable in Win2k and WinXP. This is less of a "I want to know the proper way to do this" question and more of a "I have been curious about this since I first wanted to do it in VS 2003" question. I understand that Vista's file dialog has an option to do this, but it's been working in XP so I know they did <em>something</em> to get it to work. Vista-specific answers are not answers, because Vista doesn't exist in the question context.</p>
<p><strong>Update: I'm accepting Scott Wisniewski's answer because it comes with a working sample, but I think Serge deserves credit for pointing to the dialog customization (which is admittedly nasty from .NET but it <em>does</em> work) and Mark Ransom for figuring out that MS probably rolled a custom dialog for this task.</strong></p>

31,088 | <p>I'm trying to set up an inheritance hierarchy similar to the following:</p>
<pre><code>abstract class Vehicle
{
public string Name;
public List<Axle> Axles;
}
class Motorcycle : Vehicle
{
}
class Car : Vehicle
{
}
abstract class Axle
{
public int Length;
public void Turn(int numTurns) { ... }
}
class MotorcycleAxle : Axle
{
public bool WheelAttached;
}
class CarAxle : Axle
{
public bool LeftWheelAttached;
public bool RightWheelAttached;
}
</code></pre>
<p>I would like to only store MotorcycleAxle objects in a Motorcycle object's Axles array, and CarAxle objects in a Car object's Axles array. The problem is there is no way to override the array in the subclass to force one or the other. Ideally something like the following would be valid for the Motorcycle class:</p>
<pre><code>class Motorcycle : Vehicle
{
public override List<MotorcycleAxle> Axles;
}
</code></pre>
<p>but the types have to match when overriding. How can I support this architecture? Will I just have to do a lot of run-time type checking and casting wherever the Axles member is accessed? I don't like adding run-time type checks because you start to lose the benefits of strong typing and polymorphism. There have to be at least some run-time checks in this scenario since the WheelAttached and Left/RightWheelAttached properties depend on the type, but I would like to minimize them.</p>

31,096 | <p>I'm trying to find out how much memory my own .Net server process is using (for monitoring and logging purposes).</p>
<p>I'm using:</p>
<pre><code>Process.GetCurrentProcess().PrivateMemorySize64
</code></pre>
<p>However, the Process object has several different properties that let me read the memory space used:
Paged, NonPaged, PagedSystem, NonPagedSystem, Private, Virtual, WorkingSet</p>
<p>and then the "peaks": which i'm guessing just store the maximum values these last ones ever took.</p>
<p>Reading through the MSDN definition of each property hasn't proved too helpful for me. I have to admit my knowledge regarding how memory is managed (as far as paging and virtual goes) is very limited.</p>
<p>So my question is obviously "which one should I use?", and I know the answer is "it depends".</p>
<p>This process will basically hold a bunch of lists in memory of things that are going on, while other processes communicate with it and query it for stuff. I'm expecting the server where this will run on to require lots of RAM, and so i'm querying this data over time to be able to estimate RAM requirements when compared to the sizes of the lists it keeps inside.</p>
<p>So... Which one should I use and why?</p>

<p>How on earth do I go about unit testing the WebControls? The methods are all protected or private, and since it's a framework, there isn't much else but WebControls.</p>
<p>Any pointers?</p>

31,215 | <p>I have a Person object with two constructors - one takes an int (personId), the other a string (logonName). I would like another constructor that takes a string (badgeNumber). I know this can't be done, but seems it might be a common situation. Is there a graceful way of handling this? I suppose this would apply to any overloaded method. Code:</p>
<pre><code>public class Person
{
public Person() {}
public Person(int personId)
{
this.Load(personId);
}
public Person(string logonName)
{
this.Load(logonName);
}
public Person(string badgeNumber)
{
//load logic here...
}

31,221 | <p>I have a method that where I want to redirect the user back to a login page located at the root of my web application.</p>
<p>I'm using the following code:</p>
<pre><code>Response.Redirect("~/Login.aspx?ReturnPath=" + Request.Url.ToString());
</code></pre>
<p>This doesn't work though. My assumption was that ASP.NET would automatically resolve the URL into the correct path. Normally, I would just use</p>
<pre><code>Response.Redirect("../Login.aspx?ReturnPath=" + Request.Url.ToString());

<p>but this code is on a master page, and can be executed from any folder level. How do I get around this issue?</p>

31,226 | <p>I am writing a basic word processing application and am trying to settle on a native "internal" format, the one that my code parses in order to render to the screen. I'd like this to be XML so that I can, in the future, just write XSLT to convert it to ODF or XHTML or whatever.</p>
<p>When searching for existing standards to use, the only one that looks promising is ODF. But that looks like massive overkill for what I need. All I need is paragraph tags, font selection, font size & decoration...that's pretty much it. It would take me a long time to implement even a minimal ODF renderer, and I'm not sure it's worth the trouble.</p>
<p>Right now I'm thinking of making my own XML format, but that's not really good practice. Better to use a standard, especially since then I can probably find the XSLTs I might need in the future already written.</p>
<p>Or should I just bite the bullet and implement ODF?</p>
<p><strong>EDIT: Regarding the Answer</strong></p>
<p>I knew about XSL-FO before, but due to the weight of the spec hadn't really consdiered it. But you're right, a subset would give me everything I need to work with and room to grow. Thanks so much the reminder.</p>
<p>Plus, by including a rendering library like FOP or RenderX, I get PDF generation for free. Not bad...</p>

31,238 | <p>What I have is a collection of classes that all implement the same interface but can be pretty wildly different under the hood. I want to have a config file control which of the classes go into the collection upon starting the program, taking something that looks like :</p>
<pre><code><class1 prop1="foo" prop2="bar"/>
</code></pre>
<p>and turning that into :</p>
<pre><code>blah = new class1();
blah.prop1="foo";
blah.prop2="bar";
</code></pre>
<p>In a very generic way. The thing I don't know how to do is take the string <code>prop1</code> in the config file and turn that into the actual property accessor in the code. Are there any meta-programming facilities in C# to allow that?</p>

31,297 | <p>I developed a program in a mobile device (Pocket PC 2003) to access a web service, the web service is installed on a Windows XP SP2 PC with IIS, the PC has the IP 192.168.5.2. </p>
<p>The device obtains from the wireless network the IP 192.168.5.118 and the program works OK, it calls the method from the web service and executes the action that is needed. This program is going to be used in various buildings.</p>
<p>Now I have this problem, it turns that when I try to test it in another building (distances neraly about 100 mts. or 200 mts.) connected with the network, the program cannot connect to the webservice, at this moment the device gets from an Access Point the IP 192.168.10.25, and it accesses the same XP machine I stated before (192.168.5.2). I made a mobile aspx page to verify that I can reach the web server over the network and it loads it in the device, I even made a winform that access the same webservice in a PC from that building and also works there so I don't understand what is going on. I also tried to ping that 192.168.5.2 PC and it responds alive.</p>
<p>After that fail I returned to the original place where I tested the program before and it happens that it works normally.</p>
<p>The only thing that I look different here is that the third number in the IP is 10 instead of 5, another observation is that I can't ping to the mobile device. I feel confused I don't know what happens here? What could be the problem?</p>
<p>This is how I call the web service;</p>
<pre><code>//Connect to webservice
svc = new TheWebService();
svc.Credentials = new System.Net.NetworkCredential(Settings.UserName, Settings.Password);
svc.AllowAutoRedirect = false;
svc.UserAgent = Settings.UserAgent;
svc.PreAuthenticate = true;
svc.Url = Settings.Url;
svc.Timeout = System.Threading.Timeout.Infinite;
//Send information to webservice
svc.ExecuteMethod(info);
</code></pre>
<p>the content of the app.config in the mobile device is;</p>
<pre><code><?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="UserName" value="administrator" />
<add key="Password" value="************" />
<add key="UserAgent" value="My User Agent" />
<add key="Url" value="http://192.168.5.2/WebServices/TWUD.asmx" />
</appSettings>
</configuration>
</code></pre>
<p>Does anyone have an idea what is going on?</p>

31,312 | <p>I am working on a rails project. Using the tag observe_field, I am taking text typed into a text area, processing it in a control, and displaying the result in a div (very similar to the preview in stack overflow). Everything works fine until I type certain special chars.</p>
<ol>
<li>? => causes the variable not to be found in the params object</li>
<li>(pound) => causes an invalid authenticity error</li>
<li>% => stops the div from being updated</li>
<li>& => every thing after the & is no longer passed into the variable on the server. </li>
</ol>
<p>Is there a way to solve this?</p>
<p>--- code sample ---</p>
<p>this is the view. ( 'postbody' is a text area)</p>
<pre><code><%= observe_field 'postbody',
:update => 'preview',
:url => {:controller => 'blog', :action => 'textile_to_html'},
:frequency => 0.5,
:with => 'postbody' -%>
</code></pre>
<p>this is the controller that is called</p>
<pre><code>def textile_to_html
text = params['postbody']
if text == nil then
@textile_to_html = '<br/>never set'
else
r = RedCloth.new text
@textile_to_html = r.to_html
end
render :layout => false
end
</code></pre>
<p>and this is the javascript that is created:</p>
<pre><code>new Form.Element.Observer('postbody', 0.5, function(element, value) {new Ajax.Updater('preview', '/blog/textile_to_html', {asynchronous:true, evalScripts:true, parameters:'postbody=' + value + '&authenticity_token=' + encodeURIComponent('22f7ee12eac9efd418caa0fe76ae9e862025ef97')})})

31,326 | <p>I have a few internal .net web application here that require users to "log out" of them. I know this may seem moot on an Intranet application, but nonetheless it is there.</p>
<p>We are using Windows authentication for our Intranet apps, so we tie in to our Active Directory with Basic Authentication and the credentials get stored in the browser cache, as opposed to a cookie when using .net forms authentication.</p>
<p>In IE6+ you can leverage a special JavaScript function they created by doing the following:</p>
<pre><code>document.execCommand("ClearAuthenticationCache", "false")
</code></pre>
<p>However, for the other browsers that are to be supported (namely Firefox at the moment, but I strive for multi-browser support), I simply display message to the user that they need to close their browser to log out of the application, which effectively flushes the application cache.</p>
<p>Does anybody know of some commands/hacks/etc. that I can use in other browsers to flush the authentication cache?</p>

<p>From what I can tell, only one thread can be running at once, and the active thread switches every 10 instructions or so?</p>
<p>Where is there a good explanation, or can you provide one? It would also be very nice to be aware of common problems that you run into while using threads with Python.</p>

31,412 | <p>I am developing a GPL-licensed application in Python and need to know if the GPL allows my program to use proprietary plug-ins. This is <a href="http://www.gnu.org/licenses/gpl-faq.html" rel="noreferrer">what the FSF has to say</a> on the issue:</p>
<blockquote>
<p><strong>If a program released under the GPL uses plug-ins, what are the requirements for the licenses of a plug-in?</strong></p>
<p>It depends on how the program invokes its plug-ins. If the program uses fork and exec to invoke plug-ins, then the plug-ins are separate programs, so the license for the main program makes no requirements for them.</p>
<p>If the program dynamically links plug-ins, and they make function calls to each other and share data structures, we believe they form a single program, which must be treated as an extension of both the main program and the plug-ins. This means the plug-ins must be released under the GPL or a GPL-compatible free software license, and that the terms of the GPL must be followed when those plug-ins are distributed.</p>
<p>If the program dynamically links plug-ins, but the communication between them is limited to invoking the ‘main’ function of the plug-in with some options and waiting for it to return, that is a borderline case.</p>
</blockquote>
<p>The distinction between fork/exec and dynamic linking, besides being kind of artificial, doesn't carry over to interpreted languages: what about a Python/Perl/Ruby plugin, which gets loaded via <code>import</code> or <code>execfile</code>?</p>
<p>(edit: I understand why the distinction between fork/exec and dynamic linking, but it seems like someone who wanted to comply with the GPL but go against the "spirit" --I don't-- could just use fork/exec and interprocess communication to do pretty much anything).</p>
<p>The best solution would be to add an exception to my license to explicitly allow the use of proprietary plugins, but I am unable to do so since I'm using <a href="http://trolltech.com/products/qt" rel="noreferrer">Qt</a>/<a href="http://www.riverbankcomputing.co.uk/software/pyqt/intro" rel="noreferrer">PyQt</a> which is GPL.</p>

31,446 | <p>What would be the easiest way to detach a specific JPA Entity Bean that was acquired through an EntityManager. Alternatively, could I have a query return detached objects in the first place so they would essentially act as 'read only'?</p>
<p>The reason why I want to do this is becuase I want to modify the data within the bean - with in my application only, but not ever have it persisted to the database. In my program, I eventually have to call flush() on the EntityManager, which would persist all changes from attached entities to the underyling database, but I want to exclude specific objects.</p>

31,498 | <p>I have a generic class that should allow any type, primitive or otherwise. The only problem with this is using <code>default(T)</code>. When you call default on a value type or a string, it initializes it to a reasonable value (such as empty string). When you call <code>default(T)</code> on an object, it returns null. For various reasons we need to ensure that if it is not a primitive type, then we will have a default instance of the type, <strong>not</strong> null. Here is attempt 1:</p>
<pre><code>T createDefault()
{
if(typeof(T).IsValueType)
{
return default(T);
}
else
{
return Activator.CreateInstance<T>();
}
}
</code></pre>
<p>Problem - string is not a value type, but it does not have a parameterless constructor. So, the current solution is:</p>
<pre><code>T createDefault()
{
if(typeof(T).IsValueType || typeof(T).FullName == "System.String")
{
return default(T);
}
else
{
return Activator.CreateInstance<T>();
}
}
</code></pre>
<p>But this feels like a kludge. Is there a nicer way to handle the string case?</p>

31,535 | <p>I'm trying to fetch some HTML from various blogs and have noticed that different providers use the same tag in different ways.</p>
<p>For example, here are two major providers that use the meta name generator tag differently:</p>
<ul>
<li>Blogger: <code><meta content='blogger' name='generator'/></code> (content first, name later and, yes, single quotes!) </li>
<li>WordPress: <code><meta name="generator" content="WordPress.com" /></code> (name first, content later)</li>
</ul>
<p>Is there a way to extract the value of content for all cases (single/double quotes, first/last in the row)?</p>
<p>P.S. Although I'm using Java, the answer would probably help more people if it where for regular expressions generally.</p>

31,561 | <p>Depending on my mood I seem to waffle back and forth between wanting a Lisp-1 and a Lisp-2. Unfortunately beyond the obvious name space differences, this leaves all kinds of amusing function name/etc problems you run into. Case in point, trying to write some code tonight I tried to do (map #'function listvar) which, of course, doesn't work in CL, at all. Took me a bit to remember I wanted mapcar, not map. Of course it doesn't help when slime/emacs shows map IS defined as something, though obviously not the same function at all.</p>
<p>So, pointers on how to minimize this short of picking one or the other and sticking with it?</p>

31,567 | <p>I'm trying to wrap my head around reflection, so I decided to add plugin capability to a program that I'm writing. The only way to understand a concept is to get your fingers dirty and write the code, so I went the route of creating a simple interface library consisting of the IPlugin and IHost interfaces, a plugin implementation library of classes that implement IPlugin, and a simple console project that instantiates the IHost implementation class that does simple work with the plugin objects. </p>
<p>Using reflection, I wanted to iterate through the types contained inside my plugin implementation dll and create instances of types. I was able to sucessfully instantiate classes with this code, but I could not cast the created object to the interface.</p>
<p>I tried this code but I couldn't cast object o as I expected. I stepped through the process with the debugger and the proper constructor was called. Quickwatching object o showed me that it had the fields and properties that I expected to see in the implementation class. </p>
<pre><code>loop through assemblies
loop through types in assembly
// Filter out unwanted types
if (!type.IsClass || type.IsNotPublic || type.IsAbstract )
continue;
// This successfully created the right object
object o = Activator.CreateInstance(type);
// This threw an Invalid Cast Exception or returned null for an "as" cast
// even though the object implemented IPlugin
IPlugin i = (IPlugin) o;
</code></pre>
<p>I made the code work with this.</p>
<pre><code>using System.Runtime.Remoting;
ObjectHandle oh = Activator.CreateInstance(assembly.FullName, type.FullName);
// This worked as I intended
IPlugin i = (IPlugin) oh.Unwrap();
i.DoStuff();
</code></pre>
<p>Here are my questions:</p>
<ol>
<li>Activator.CreateInstance(Type t) returns an object, but I couldn't cast the object to an interface that the object implemented. Why?</li>
<li>Should I have been using a different overload of CreateInstance()?</li>
<li>What are the reflection related tips and tricks?</li>
<li>Is there some crucial part of reflection that I'm just not getting? </li>
</ol>

31,584 | <p>For classes that have a long list of setters that are used frequently, I found this way very useful (although I have recently read about the <a href="http://en.wikipedia.org/wiki/Builder_pattern" rel="noreferrer">Builder pattern</a> in <em>Effective Java</em> that is kinda the same).</p>
<p>Basically, all setter methods return the object itself so then you can use code like this:</p>
<pre><code>myClass
.setInt(1)
.setString("test")
.setBoolean(true);
</code></pre>
<p>Setters simply return this in the end:</p>
<pre><code>public MyClass setInt(int anInt) {
// [snip]
return this;
}
</code></pre>
<p>What is your opinion? What are the pros and cons? Does this have any impact on performance?</p>

(Please, correct me if I'm wrong here.)

<p>I should note that this is a XP Embedded application on a closed system where we can't use the built-in Wireless Zero Configuration (WZC). We have to build all Wifi management functionality into our .NET application.</p>

<p>@Josh exactly. Though maybe it would show the deleted text in red or something. The idea is that if I use a WYSIWYG editor for my HTML content, I don't want to have to switch to HTML to do diffs.
