     if (( hwndEdit == GetDlgItem(IDC_EDIT) 
     || ( hwndEdit == GetDlgItem(IDC_COMBO))
     {

      // current Color brush. If this is the first time through
      // we need to create it. The brush is deleted in the destructor
      if ( m_hBrush == NULL )
       m_hBrush = CreateSolidBrush( RGB(255,0,0)
     )
     
      // Get the DC provided and set the appropriate attributes
     
      SetBkMode(hdcEdit, TRANSPARENT );
      SetBkColor(hdcEdit, RGB(255,0,0));
    
      // Return a handle to the brush
      HBRUSH far* hbr = (HBRUSH far*) m_hBrush;
      return ((DWORD) hbr);

    If We have 1 Combobox then We can change Background color and TExtColor easily For Example: case WM_CTLCOLOREDIT: SelectObject((HDC)wParam, hFont); SetTextColor((HDC)wParam, RGB(255, 0, 0)); SetBkColor((HDC) wParam,RGB(255,206, 129)); return (LRESULT) (HBRUSH)CreateSolidBrush(RGB(255,206, 129));
