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 at 00de:48737953"

With Windows 98, you may receive the following error:

"VB5 caused a divide error in module VBA5.DLL at 015f:0faf74c1"

With Windows NT or Windows 2000, you may receive the following error.

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.
