Contrary to VB, forms are not self-instanciable. If the name of your form 
class is "MyForm", it doesn't mean that you have an instance of this form 
with the same name like in VB.

You must instanciate MyForm, and put the resulting reference in a global 
variable.

For example:

In MyForm:

STATIC PUBLIC Handle AS MyForm
...
Handle = NEW MyForm
...
MyDialog.Dialog
...
PUBLIC SUB ChangeLabel()
 ...
END

In MyDialog:
...
MyForm.Handle.ChangeLabel
...

Is it clearer ?
