thanks.. i have tried it.. but still the name of the sub doesn't seem to appear on the other form.. :(.. is there other solution for it?

Sorry, no. It's enough to make the class internal. It's a good idea to give as little access as possible.

but is that posible to access class code on the form? like for example on vb.net on a module.. all you have to put is just this codes..

Module Module1
Public Sub sample_sub()
'this is a sample sub
End Sub
End Module

and you can just simply call the sub on whenever form you use, for example "call sample_sub()".. is it posible on c# .net?

You are not yet prepared to ask productive questions here. You should first read about the basics. If this can provide you with some hints, look here:

C#

internal class SomeClass {
    internal static void StaticMethod() {/* ... */}
    internal void InstanceMethod() {
        this.A = 5; // you can only do it in instance methods
        // same as
        A = 5; // but "this" can resolve name conflict and important 
               // for understanding of what's going on; see also below
    }
    //...
    int A;
}

// ...

SomeClass.StaticMethod();

someInstance SomeClass = new SomeClass();
someInstance.InstanceMethod(); // the reference "someInstance" becomes "this" passed to the method
                               // as an implicit parameter, see above
