In a message dated 11-0894, Simon Ewins said to Dean Roddey:

SE|    hwdlg=WinLoadDlg(HWND_DESKTOP,hwnd,dBoxDlgProc,0L,DBOX_DLG,NULL);
  |    htext=WinQueryWindow(hwdlg,DBOX_TEXT);
  |    WinSetWindowText(htext,"The prompt I want to use:");
  |    WinProcessDlg(hwdlg);
  |    WinDestroyWindow(hwdlg);

Did you test the value of htext being returned?  I'll bet it is invalid.
The dialog box is not actually a working "window" until sometime
just before the WM_INITDLG message is called within your dBoxDlgProc.  This
is where you need to do your field queries and text setting.

You're trying to query a window handle and set its text before it's
accepting messages.  Its message loop doesn't start until WinProcessDlg is
called.

I still do this kind of thing regularly (try to manipulate a window before
it's really a window :).  That's one of the first things I check my own
code for!
