Re: calling a parent window class method from a child window class

Hello Gregory

Based on my experience it is always better working with events ...
Anyway, in your child window .cpp file, you could try to use the code below 

# include "MyParentClass.h"

CMyParentClass* pParent = (CMyParentClass*)this->GetParent();
pParent->MyMethod( ... );
