I'm using the XTreme Suite. Does anyone know how to create a MDI application so that the client edges are flat? Ive included an image of the area.

Hello,

Override the WindowProc virtual function for your view and add the following code:

LRESULT CSampleView::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)
    {
    case WM_NCPAINT:
        {
           CWindowDC dc(this);

           CRect rc;
           GetWindowRect(&rc);

           int cx = rc.Width();
           int cy = rc.Height();

           const COLORREF clrFrame = GetXtremeColor(XPCOLOR_3DSHADOW);
           dc.Draw3dRect(0, 0, cx, cy, clrFrame, clrFrame);

           return TRUE;
        }

        case WM_NCCALCSIZE:
        {
             NCCALCSIZE_PARAMS FAR* lpncsp = (NCCALCSIZE_PARAMS FAR*)lParam;

           // adjust non-client area for border space
           lpncsp->rgrc[0].left += 1;
           lpncsp->rgrc[0].top += 1;
           lpncsp->rgrc[0].right -= 1;
           lpncsp->rgrc[0].bottom -= 1;

           return TRUE;
        }
    }

    return CView::WindowProc(message, wParam, lParam);
}
