I've been working for years with VS's debugger, but every now and then I come across a feature I have never noticed before, and think "Damn! How could I have missed that? It's so useful!" [Disclaimer: These tips work in VS 2005 on a C# project, no guarantees for older incarnations of VS or other languages] Keep track of object instanc...
I have a strange issue: I am using SPContext.Current.Web in a .aspx page, but at the end, I get a "Trying to use an SPWeb object that has been closed or disposed and is no longer valid." error message. From what I see, SPContext.Current.Web is Disposed by someone, but I have no idea where. I just wonder: With Visual Studio 2005's Debugg...

I've inherited a .NET application that pulls together about 100 dlls built by two teams or purchased from vendors. I would like to quickly identify whether a given dll is a .NET assembly or a COM component. I realize that I could just invoke ildasm on each dll individually and make a note if the dll does not have a valid CLR header, but ...
Our WinForms application has been reported to occasionally just close on its own. It neither shows our own crash error submit dialog nor Windows' error submit dialog, it just closes and is gone, often when the person was afk and not doing anything with the application. It seems to be a semi-rare occurrence, maybe like 2-3 times a month...
Hi, I have some code which returns InnerXML for a XMLNode. The node can contain just some text (with HTML) or XML. For example: <XMLNode> Here is some <strong>HTML</strong> <XMLNode> or <XMLNode> <XMLContent>Here is some content</XMLContnet> </XMLNode> if I get the InnerXML for <XmlNode> the HTML tags are ret...
There are two scenarios I need to clarify: An executable compiled with .NET 3.5 needs to use a library compiled with .NET 1.1 and the library must run on the 1.1 runtime. An executable compiled with .NET 1.1 needs to use a library compiled with .NET 3.5. I cannot find a reliable source stating that it is not possible to load two vers...
I have a Java applet that runs inside a forms-authenticated aspx page. In the .NET 1.1 version of my site, the applet has access to the session cookie and is able to retrieve a file from the server, but in the .NET 2.0 version it fails to authenticate. I have seen a couple of forum posts elsewhere that state that 2.0 sets cookies to Htt...
I have an HttpHandler on my webserver that takes a URL in the form of "https://servername/myhandler?op=get&k=Internal&m=jdahug1". I need to call this URL from my .NET app and capture whatever the output is. Does anyone know how I can do that? I want it to be simple so that I just get back a string with the output, and that I c...
I have an ASP.NET web page with a Login control on it. When I hit Enter, the Login button doesn't fire; instead the page submits, doing nothing. The standard solution to this that I've found online is to enclose the Login control in a Panel, then set the Panel default button. But apparently that doesn't work so well if the page has a ...

I have the same problem as described in the posts listed below. That is, certain keys don't work at all when I type them into my combobox until I first hit the spacebar.

I'm living in nightmares because of this situation, I have a HttpWebRequest.GetResponse that keeps on giving me a ThreadAbortException, that causes the whole app to go down. How can I avoid that, or at least handle it, would using Thread.ResetAbort() be useful in such a case? To explain more here is a rough code sample: HttpWebRequest...
Often times I need a collection of non-sequential objects with numeric identifiers. I like using the KeyedCollection for this, but I think there's a serious drawback. If you use an int for the key, you can no longer access members of the collection by their index (collection[index] is now really collection[key]). Is this a serious enough...

When developing custom ecommerce solutions, which "off the shelf" .NET based shipping components have you had luck with? It absolutely must give real-time shipping quotes and be easily integrated into a ASP.NET website.
