What I am uncertain of is if I am correctly using the WebRequest object to do the posting. I am setting the M...

All the refactoring tools for C# and VB.Net that I have seen only consider the source code in a single visual studio solution. For better or worse, our large (many related programs) system is spread over many solution files, however: All the code is below a single windows folder. Our nAnt based build system, builds all files in a win...

I recently made the switch to a new job and consequently the switch from VB.NET to C#. One thing that I miss is all the snippets that are available in VB.NET. VB.NET comes with ~400 snippets and C# only comes with ~100. Also, I have noticed that the majority of VB.NET snippets are task oriented which is exceptionally helpful when you ...
We have a multi-line control that we are attempting to prevent the Enter/Return key from being used to create a new line. Strangely enough, "AcceptsReturn" as False does not prevent this. So we added the following: Private Sub txtAddr_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAddr.K...

I populate the List (called myList), set myList as the DataSource in the BindingSourc...

This is an ASP.NET we...
