hello All

I am wondering if it is possible to change the background colour and text colour in a list box using MFC.  I tried to look at the CListBox class and there seems to be no member functions that could do this.

I look forward to your reply.

Best Regards

Asif

It is possible.

You need to handle the WM_CTLCOLOR message in the parent dialog. In this message handler you can change the default colors.

Here is an example:

HBRUSH CTestAppDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    static HBRUSH hMyBrush = NULL;

    HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
      
    if(CTLCOLOR_LISTBOX==nCtlColor)
    {
        pDC->SetTextColor(RGB(255,0,0));
        pDC->SetBkColor(RGB(0,255,0));
        if(!hMyBrush)
            hMyBrush = ::CreateSolidBrush(RGB(0,0,255));

        return hMyBrush
    }
    return hbr;
}

This will make the text red, background of text green, and clientarea of control blue.
