| opening forms using a button (3 replies) |
| microsoft.public.dotnet.academic |
| Let's assume I have two forms (A and B) in a project. In previous versions of VB I could have a button on Form A with a click event that opened Form B by simply using the command "B.show" and Form B would have opened up. Now, in VB.NET I want to do the same thing but it won't work. Can someone please tell me what I'm doing wrong...or how I can accomplish this task. Thanks!! |
