My program seems to be creating the static splitter itself okay. The problem comes in when I try to create the view by calling: m_mainSplitter.CreateView( 0, 1, RUNTIME_CLASS(CSplitView), CSize( 150, cr.Height() ), pContext ) CSplitView is the default view class created by the app wizard (I havn''t touched it, maybe that''s the problem im super new to mfc) the compiler generates the following message: C:\Split\MainFrm.cpp(83) : error C2653: ''CSplitView'' : is not a class or namespace name C:\Split\MainFrm.cpp(83) : error C2065: ''classCSplitView'' : undeclared identifier I''m just trying to get this working before I move on to specialized views. Thanks; Prairie

Try adding

class CSplitView;

to the top of your mainframe.h.

Then add the #include path of CSplitView''s header file to the top of mainframe.cpp.
