Using OfficeXP or Office2003 style for MDI interfaces, where you get tabs for documents, produces flicking when switching between documents. In one of your examples i saw the code where you adjust initial size of documents to avoid flicking to be too obvious, i.e. when frame window is redrawn more often than needed. However, this still leaves the issue with flicking, and it is way different visually from when using normal MDI presentation without tabs.

Any chance to fix that?

I have the same problem about which I posted a while ago (no reply though)...

Got it! You always have to override on erase background like this:

BOOL CTemplateEditorView::OnEraseBkgnd(CDC* pDC)

{

return TRUE;

}

Doesn't help me in the View class, perhaps it should be in the Frame holding the View?

Thanks,

no, for me it made a world of difference:

1. onerase returns true

2. background is drawn from within CView::OnDraw

3. The view is derived from CScrollView

Check out their example called drawcli.exe, and the project itself where they solved the problem with flickering.

Well, my view is derived from CXTPReportView and the area that flickers is only the top part where it says "Drag column headers here...", the rest of it doesn't flicker even without overriding the OnEraseBgnd(), I guess it's a different case.
