Question : OnCtlColor and multiline edit - odd behaviour

I have a multi line edit control on a dialog (no subclassing of the edit control).  In the dialog I have the following code

HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
      HBRUSH hbr = CMyDlg::OnCtlColor(pDC, pWnd, nCtlColor);

      // TODO:  Change any attributes of the DC here
      if(nCtlColor == CTLCOLOR_STATIC)
      {.....
      }
      else if(nCtlColor == CTLCOLOR_EDIT)
      {
            UINT nID = pWnd->GetDlgCtrlID();
            switch(nID)
            {
            case IDC_EDIT_BENEFICIARY:
                  pDC->SetBkMode(TRANSPARENT);
                  return (HBRUSH)m_brBeneficiary;
            }
      }

where m_brBeneficiary is a CBrush aand set as follows in the c'tor
      m_brBeneficiary.CreateSolidBrush(RGB(255, 0, 0));


When I type into the edit control I get text as in picture 1 (sort of bold font - WRONG), now if I select some text in the control the font appears as I want it to appear see picture 2.  <Picture 3 shows what happens without the OnCtlColor>

Any ideas what is going on and more important how to get it to work correctly.

Answer : OnCtlColor and multiline edit - odd behaviour

Hi Andy,

I think the problem is the 'pDC->SetBkMode(TRANSPARENT);' because this causes the control to draw the entered text just over the existing (and I guess for some reason the font mapping makes the font getting bold after some entered text) - you can simply verify this by entering some text and then deleting using backspace ...

So I would suggest to not use 'pDC->SetBkMode(TRANSPARENT);' - instead use 'SetBkColor' to set the text's background color to the same as the brush's color, i.e. 'pDC->SetBkColor(RGB( 255, 0, 0 ));' for a red filled edit control.

Hope that helps,

ZOPPO
