Calling function in a child window from main parent window

Mar 12th, 2006

Hi all...

This is the case:

I have a main parent window, and a child window inside it.
The parent window consists of a menubar, whereby clicking one of its menu item (mnuSave) is supposed to save the graph drawn inside the child window. The code for saving the graph is done by a method called SaveGraph(). I tried calling the method from the main parent window, but then an error occured saying "TestProg.ChildWin.zedGraphControl1" denotes a 'field' where a 'class' was expected.

The following illustrates better :

Inside parent window (TestProg)
