I have created 5 different projects in VB in Visual Studio. Pretty basic stuff, but all have different functions that they perform. I have added all projects into one solution just to show them in a linear fashion to management for evaluation. I really do look up basically everything I've learned, but it's late and I'm tired. How can I go from 1 windows form in 1 project to another in a different project. I'm guessing it's stupid simple but thought I'd try my first forum question. Thanks in advance for any help.
