Ending a VB program
Problem:
I am using VB6.0 as my developing environment. I am unable to properly end my program on a clean 95 machine. I get the error: "dmsUser caused an invalid page fault in module MFAC42.dll"
My thoughts:
I had thought that I wasn't unloading all forms, but this did not solve the problem. I also thought I wasn't hitting the end. But the error seems to occur when I hit the "END"
Has anyone had a problem like this? What did you do to fix it?? This error only occurs on Windows 95 machines, where VB is not loaded.
Thanks in advance.

Do you use the DataReport Designer ?
ASKER
No we do not use the DataReport Designer
This may or may not solve all your problems but you should never use End to terminate your program. Unload your forms and set them to nothing.
You should also explicitly destroy all object variables and close any connections to files or databases.

I do unload all forms, and set the main form = nothing. I also close my connections to the DB. Should I set all forms = nothing?
try doing
dim f as form
for each f in forms
if f.hwnd <> me.hwnd then
unload f
set f= nothing
end if
next f
unload me
this will unload all other forms before yours.
dunno if it will solve ur prob though

Thank you for your help.. I am building with a MFC42.dll, and the 95 machine has a 4.2 version of the MFC42.dll
Thanks again!
Thanks again!
Visual Basic Classic
Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
