Hi! My honourable friends:

Can anybody out there can tell me under what circumstances the EndDialog
procedure will fail?

The story is:

I compiled and linked the programme listed on P548 (Chapter 10,
dialogbox) of Petzold's book 'Programming Windows', e.g. the file dialog
box subroutines. Compile ank link ok. When I run it, I clicked the OK
button, my Windows goes hung! (I clicked the Cancel button, it works
well). I used Turbo debugger (My compiler is Borland C++ 2.0) to trace
this programme, every step seems to work well until the programme comes
to the EndDialog(hdlg,TRUE), debugger tell me : Exception 13 Error code
532. What's wrong ? I think the Mr. Petzold's programme is ok except the
resource file defines the dialog box too small.

Please Help ! and I found the DEFPUSHBUTTON does not work, I mean when I
press enter, it does not generate a IDOK message.

Thank you in advance.
