I copied the following code from the MSDN reference article for the Print method of the PrintDocument object located here. My question is simply, where does this go? I am using Visual Studio 2008 professional. I've tried creating a blank project, and a win32 console project. If I try to create a module and copy the code into there I get an error about the module not containing a Sub New(). So I write a Sub New that instantiates the class, and when I try to run it from the command line, it doesn't recognize my arguments.
Am I wrong in assuming that there is a place or a way that I can simply create a new project, paste in this code, compile it as it is, and run it?
Thanks in advance for any help on this. I truly have searched for this answer before posting.
