How can I communicate with the view through the main window class? 2 ideas: CFrameWnd::GetActiveView() and cast to your view class or keep a pointer to your view as a member of your frame class. Set it in OnCreate(...) Now if only someone would answer my question. I did this for good karma :)

Thanks everyone. After a long and hard battle trying to do it myself without the wizard I have to admit to defeat. I cannot get it working without having debug assertions flying left and right. So I have seen the err in my ways and have switched to the dark side. After only about twenty minutes of getting familiar with the wizards I finally have my splitter window working. :)
