I've made a simple MFC dialog app. It does stuff after a button is
clicked, and shows progress text in an edit box. Unfortunately the
edit box text is not updated when I want it to be. Although the calls
to UpdateData return success, the new text is not actually shown until
the "do stuff" function is complete; that is, all of my progress text
is shown too late.
OK that's happening because your busy loop isn't allowing Windows
messages (specifically the WM_PAINT) message to be processed until
after it's finished.
I have a progress dialog that I put up while measuring to print/preview.
The call goes:
void CProgressDlg::SetProgress( LPCTSTR display, long at )
{
lastProg= at;
ctrlText.SetWindowText( display );
ctrlProg.SetPos( lastProg );
}
It works just fine. It may be because he was using UpdateData.
Not all painting is done through the WM_PAINT message handling.
Both of those calls cause the controls to redraw themselves immediately.
