Hi All,

I have a ToolkitPro application that I am working on and I am having a problem with the redrawing. When I resize the Main frame window the whole application flickers, including menus, command bars and statusbar. I am using the theme kit as well as the outlook bar. On the right hand side of the outlook bar I have a regular CView derived object which uses CXTMemDC for drawing. I am not sure what I could be doing wrong as the demo applications don't flicker at all. Is it possible that I am using too many resources?

I am also running my screen resolution at 1600x1200 on a dual Pentium III 866 on Windows XP Professional.

It seems that the main window has set the CS_HREDRAW/CS_VREDRAW style. Just define your own window class instead.

It seems that is not the case. Any other ideas of what would be causing a complete redraw everytime I resize?

I had such problem when in CMainFrame::PreCreateWindow of MDI frame

call CFrameWnd::PreCreateWindow instead CMDIFrameWnd::PreCreateWindow....

Try adding this to your CMainFrame::PreCreateWindow method:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;

// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

    // Helps to reduce screen flicker.
    cs.lpszClass = AfxRegisterWndClass(0, NULL, NULL,
        AfxGetApp()->LoadIcon(IDR_MAINFRAME));

return TRUE;
}

Let me know if this helps.

Kind regards,
