How to change the text color in a disabled edit box using MFC?

Question

Hello all,

I have a dialog in which the edit box is disabled but the text should be displayed in red instead of the default grey. I tried the following:

void CMyEdit::OnEnable(BOOL bEnable)
{
  CEdit::OnEnable(bEnable);

  if (bEnable)
  {
    m_BackGroundColor = kRGBWhite;
  }
  else
  {
    m_BackGroundColor = kRGBDefaultGray;
  }

  m_TextColor = kRGBRed;
  m_BackgroundBrush.DeleteObject();
  m_BackgroundBrush.CreateSolidBrush(m_BackGroundColor);

  Invalidate();
}

But its still displaying the text in grey only. But if I remove the base class call CEdit::OnEnable(bEnable); then new text color takes effect. Can anyone explain whats wrong in the code?

Thanks for your time.

cheers...

You need to handle OnCtlColor handler and in your message map put this ON_WM_CTLCOLOR()

afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
 //logic here, change pDC as needed, return brush to use
}
