There are a few ways to do this but I've chosen to use the AttachedTemplate property, as such: Dim oWord As New Word.Application() oWord.Visible = False Dim oDocuments As Word.Documents = oWord.Documents Dim oDo...

The features are almost the same so that my extended customizations can work for both, but I have to recompile for each version because they have different version assemblies.

What factors dictate throwing an exception if argument is null (eg if (a is null) throw new ArgumentNullException() ), as opposed to checking the argument if it is null beforehand. I don't see why the exception should be thrown rather than checking for null in the first place? What benefit is there in the throw exception approach? This...

Hi I am wondering if anyone has any good tutorials(or maybe even a library that is already made and well documented) on making a generic repository. I am using currently linq to sql but it might change so I don't know if you can make a generic repository that would take little to no changes if I would say switch to entity framework. T...
I'm drawing directly to the screen using BitBlt and GetDC(IntPtr.Zero). Is there some way to call Refresh or Invalidate on the whole screen when I'm done, so that I don't leave big chunks of paint everywhere (digitally speaking)? Update: when you draw directly to the screen like I'm doing, whatever you draw remains there until the win...
I'd like to capture signatures of application users with a mini-tablet/little pos signature device. I welcome any first hand experiences of which ones were good and which ones to stay away from.
