problems with... MDI and Splitter::CreateView.

[DerekSaw]

Previously, the app is SDI... but the I want to change it to MDI. So, CMainFrame (before derived from CFrameWnd) is derived from CMDIFrameWnd. But somehow rather, problems happen in here, the CreateView under OnCreateClient().... Anyone know the DO's and DON'Ts I need to know when converting from SDI to MDI.... // MainFrame.cpp .... BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { ... // Add the filter view if (!m_wndSplitterTop.CreateView(0, 0, RUNTIME_CLASS(CFilterView), CSize(cxUpper, 0), pContext)) ... } ...

If you converting an SDI app where the view was split (two views onto the one document), you'd normally map that to an MDI application where each document frame (CMDIChildWnd) is split into two views. So, you don't want to modify your CMainFrame class (now derived from CMDIFrameWnd), you want to derived a class from CMDIChildWnd, add a splitter and override its virtual OnCreateClientClient() call. Then modify the CMultiDocTemplate created in the applications InitInstance() function to use your derived class rather than CMDIChildWnd. Stephen C. Steel Kerr Vayne Systems Ltd.

:) Thanx 4 the help. Can I create splitter window (and its view) on CMDIFrameWnd? I was thinking of doing something like VC++ where the Workspace is on the left of the splitter, and Output below another splitter, leaving the space left for ChildWnd. Any clue on these??
