CStatusBar.

Hi,
I have a CStatusBar object that I am trying to update from a thread. The CStatusBar object is
a public member of my CMainWnd, and I am trying to update it with Cwnd::SetWindowText. I
tried SetPaneText, but that didn't work either. In fact, the only time it did work was when I had
a debugging messagebox showing, and so the paint message was being processed. I tried
sending the paint message manually with ::SendMessage, but that didn't work either. Does
anybody know what is the problem?
Thanks,
Eoin.

Call your worker thread with the handle to the main window:

AfxBeginThread(DoSomething, this->m_hWnd);

Then your worker thread has something to update:

// Worker process to do something
UINT DoSomething(LPVOID pParam)
{
      HWND hWnd = (HWND)pParam;

      ::SetDlgItemText(hWnd, IDC_STATUSBAR, "Yo!");
      return 0;    // thread completed successfully}
}

Great!!! Thanks. It didn't quite work, as I was already passing a configuration structure through
the LPVOID pParam, but you set me on the right track, I used:
::SetDlgItemText( AfxGetMainWnd() ->m_hWnd, IDC_STATUSBAR, "My Text");

Thanks again.
Eoin.
