I'm obviously doing something wrong in WordBASIC, but I can't figure out
what. Here's the situation.
I built a WordBASIC dialog box with an OKButton, a CancelButton, and a
ListBox. If I choose the OKButtong, I get the expected results and can
proceed with the next action based on my list selection. However, I run
into problems when I press CancelButton and want to act on it.
The WordBASIC ref manual says that I can use
On Error Goto 0
to ignore the error generated by CancelButton and use the Err value that is
returned. However, using 'On Error Goto 0' doesn't seem to do anything.
I still get a runtime error and cannot process the error code returned
by Err. I tried 'On Error Resume Next' and that seems to work as
advertised (the cancel generated error is ignored and the next
WordBASIC instruction is processed).
Any hints would be appreciated...todd

You need to place an On Error Goto EndLabel on the line *before* the statement accepting cancel. So, for instance, in displaying a dialog box you would have <dialog definition> ... On Error Goto EndLabelName Dialog Dlg On Error Goto 0 ... Statements when not cancelled ... EndLabelName 'Marks the end of the macro End Sub You might be interested to know that Microsoft is giving away a short (170) page introduction to WordBASIC called Using WordBASIC. Call 1-800-426-9400 and ask for the WordBASIC Binder for the PC (there is also one for the Mac, be specific), part number 059-050-574. Not every operator is up on this promotion: but be assured, the first copy of Using WordBASIC is free. Additional copies are 15.00. Also, there is a new addition of the Technical Reference.
