Summary: dialog: no wm_paint message at first draw
           Product: Wine
           Version: 20050930
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In a program I want to create a (modal) dialog (like in petzold), but
additionaly I've inserted in the message handler code to draw something when
WM_PAINT is received (besides other things defined in the resource file). with
wine this wm_paint code isn't called at the very first startup of the dialog,
but afterwards (e.g. at repainting) all is ok.
e.g.
(handle messages of the given dialog)
  case WM_PAINT:
    hdc = GetDC (hDlg);
 /* draw something */
    ReleaseDC (hDlg, hdc);
    break;
