Seems like a paint issue. Try overriding the OnEraseBkgnd() function.Write the code to put color on the screen there. Hope this works out for you.(never tried this though...) cheers! PS:do comment or call the CDialog::OnEraseBkgnd( pDC ) first before putting in your paint code

Hi Handle the WM_CTLCOLORDLG and place your painting code inside the handler.
HBRUSH CBkColorDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); // TODO: Change any attributes of the DC here if(nCtlColor == CTLCOLOR_DLG) { hbr = CreateSolidBrush(RGB(2,22,222)); } else if(nCtlColor == CTLCOLOR_STATIC) { pDC->SetBkMode(TRANSPARENT); hbr = CreateSolidBrush(RGB(2,22,222)); } // TODO: Return a different brush if the default is not desired return hbr; }that's it Regargs Nitheesh -
