SYMPTOMS

When you compile or run your Visual Basic 5.0 project, you receive an error and Visual Basic 5.0 shuts down.

With Windows 95, you may receive one of the following errors: 

   “VB5 caused a divide error in module VBA5.DLL at 0137:0faf74c1”

    - or -

   “VB5 caused an invalid page fault in module <unknown> at 00de:48737953”
With Windows NT, you may receive the following error. 

   “Exception: Divide By Zero (0xc0000094), Address 0x0faf74c1”

CAUSE

You may receive this error if you attempt an operation with the Modulus operator on two literals where the divisor evaluates to zero.

You will not receive an error if one or both of the Modulus arguments is a variable. If one or both of the Modulus arguments is a variable, you will receive a run-time error 11 "Division By Zero" as expected.
