Hi!
I have a question:
In mainform 's source code, how can I know which other forms are showed, and how can I control these forms from mainform, such as calling a method in each of these forms?

Plz help me!
Thank you very much.

Which forms are showed?

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
