Answer 1

• Attach your Vc to the program.
• Enable catch of all exeptions.
• Close your application and see where it stops.

Answer 2

You just run it under your IDE, it will show the location of the exception. If you do not have an IDE; note the address of the exception from the information dialog, look that address up from the MAP file generated with the EXE and try to locate the function...
