When attempting to output an empty textarea element, the .NET XSLT processor collapses the element to its short form. Instead of this: <textarea id="blah" name="blah"></textarea> I get this: <textarea id="blah" name="blah"/> Which causes many web browsers (including IE and Firefox) to render the rest of the page as if it were the c...

The project I'm working on is a piece of static HTML with some inline JavaScript that will call a REST web-service, which I'm creating myself using .NET 3.5 WCF. The JavaScript will grab some details from the user including an email address, then send those details off to the web-service through Ajax. The web-service will then store the...
I know that platform agnostic .NET applications "float up" to the bitness of the operating system. But what about a .NET assembly that is a library, not an executable, being called from a non-.NET application? We have a .NET DLL that is a CLR extended stored procedure for SQL Server 2005. Currently it is platform agnostic. What happens ...
I have a .Net program that, as one of its functions, takes a file from a user-specified directory and puts it in another, special, directory, specified via UNC (which may or may not be local). I don't open any of these files in this part of the code. There's this bizarre bug I'm having where, on a Windows Server 2003 SP2 VM, this progra...
DataSets were one of the big things in .NET 1.0 and even now when using .NET 3.5 I still find myself having to use them....especially when I have to call a stored proc which returns a dataset which I then end up having to manually transform into an object to make it easier to work with. I've never really liked DataSets and have found th...

Hi, I'd like to gain control over the construction of a WebService instance in ASP.NET. This is what I did so far: I created a .ASMX file and pointed it to a Class with WebServiceBinding and WebMethod attributes attached to it as usual. At the time I browse to the .ASMX file ASP.NET will automatically create an instance of the Class fo...
We have had problems for the past year whereby when users upload files to the server very few files will just not upload via a simple HTTP form. These files have been of varying sizes and types but for some reason they will not upload. Often ZIPing them up will help resolve the problem but ideally the user should not have to do this an...
Hello. As far as I know, in C# all fields are private for default, if not marked otherwise. class Foo { private string bar; } class Foo { string bar; } I guess these two declarations are equal. So my question is: what for should I mark private variables as private if they already are private? ...

Now, when I change a property which influences the ToString, I'd like to get the ListBox to update. How can I do this 'quick and dirty' (like repaint). Is dependency proper...
