I have an
application which is causing me trouble, but I am at a loss as to how to debug
it.
I need to describe
the application and how it works, so that you can understans my problems so here
goes:
Its a data
viewing/editing application for the roading industry.
There is a list of
roads from which the user can select 1 or many roads.
The user
can view any number of MDI forms which contain information on things like
Signs, Street Lights and Footpaths.
When a user selects
a new road we fire a windows message off which the data forms recieve and update
themselves.
We have other
messages flying about when different events happen, like one of the data forms
scrolls.
The problem is
arising when I close one of these data forms. I get an access violation after
the destructor has completed. The application is in the message loop when the
access violation occurs, so I don't get much from the call
stack.
I assume (but I
could be wrong) that the exception is occuring because there is still a message
in the queue which is destined for the form that has been
free'd.
How do I go about
debugging a problem like this?
Thanks
Stacey
