I am trying to get my project to validate a serial number using a DLL or EXE file I have written instead of the included algorithm, but I have no clue how to get the Customer Information dialog to read from a DLL or EXE file or if it is even possible.  I have searched through other threads and haven't found anything extremely useful.  I am using Visual Basic .NET and Visual Studio .NET 2003.  Can anyone help me with this?
