When I make a dialog box (one message label and one button) modeless,
the button never fires any event. I want to create a dialog box which
displays a changing message - say number of records read, etc. and has a
cancel button to abort the process. I am able to reset the message
periodically, but when I click on the button, nothing happens. If I make
the dialog box modal, the button works but the system get stuck until I
click the button.

I am attaching snippets of the code. Can any one please advise?
