Good morning, all!
I'm, working my way through "Microsdoft Office 200 VBA Fundamentals" Chapter
4, looking at displaying a "File Open" dialog box. The downloaded code works
fine, in terms of returning a value when a filename is selected, except that
when I press "Escape" whilst the box is open, at which point I get "Code
Interruption has been interrupted", at the code marked with a #. Can anyone
suggest what's happening. The equivalent code, to display a "browse for
folder" works fine, and correctly clears the dialog box when escape is
pressed.
