Override the OnCtlColor memober function of your CDialog derived class and return a yellow HBRUSH for that control ID of the CEdit you want changed.

Yes, it happens.  Some "experts" post an "Answer Coming" right away and then post the real answer at their lesiure.  In my opinion, that's tacky.

Actually, your function is missing some stuff:

HBRUSH CPaddsCvtDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
 
    //
    //  If My Control Is Asking For Its Colors, Set Them.
    //
    if( pWnd->GetDlgCtrlID() == IDC_PADDSASCII )
    {
        pDC->SetTextColor(RGB(0,0,0));                  // Set Text Color
        pDC->SetBkColor(RGB(255, 255, 0));      // Set Text BG Color
        return(::CreateSolidBrush(RGB(255, 255, 0)));                  // Return BG Brush
    }
   
    //
    //  If Not My Control, Just Do The Default.
    //
    HBRUSH hBrush = CDialog::OnCtlColor( pDC, pWnd, nCtlColor );
    return( hBrush );
}

What is missing?  The explicit colors?  That is what the member variables are for...

Thanks jhance for your solution .
This works fine only if the  R G B values are 0,255,128 ( pure colors only).I also needed to specify pDC->SetBkMode(TRANSPARENT);
 It does not draw transparent for non-pure colors.
Is there any way to do that ?
