Hi Inpras,

I have already done that. I just wanted to ask for a way ti amke it grey. It is already disabled with EnableWindow(FALSE) but it is still in white color. I need to be grey to show user that it can not be changed.

Sorry for missunderstanding

regards

Try this:
Note, I don't know the RGB for grey but that should not be a problem to find

Add a member variable like this
CBrush m_WhiteBrush;

in your OnInitDialog,
m_WhiteBrush.CreateSolidBrush(RGB(255,255,255)); // This brusk is white

then add this method
HBRUSH YourClass::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = YourBaseClass::OnCtlColor(pDC, pWnd, nCtlColor);

if ( pWnd->GetDlgCtrlID() == IDC_YOUR_CTL_ID )
{
if ( nCtlColor == CTLCOLOR_STATIC )
{
pDC->SetBkColor(RGB(255,255,255)); // This background is white
hbr = m_WhiteBrush;
}
}

return hbr;
}

It worked for me when I wanted to have a readonly edit box with a white background

Hi mzdravko

1 Create a brush with grey color

2 map the OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

in this fn write the fol code
      if (pWnd->GetDlgCtrlID() == IDC_CHECK1)
      {
//You can check here for the getcheck
if(m_Check.GetCheck())
{
            pDC->SetBkColor("Your color");
            hbr = m_WtB;
}
      }
and to prevent user to change it
//in onclick event
3 void CCheckDlg::OnCheck1()
{
      if( !m_Check.GetCheck())
      {
            m_Check.SetCheck(TRUE);
      }
}
Hope this helps

Regards
