Hi,

I am running VFP5a with service pack 3.
There are two kind of illegal operation that I get on my system.

01) myapplication.exe caused a stack fault in module vfp500.dll at 0137:10001023
This error will only cause the current application to exit, leaving the other
two application intact.

02) myapplication.exe caused a invalid page fault in 0137:00403050
This error will cause my current application and other 02 application to exit
too.

As for the line giving the error, it is random, I can't pinpoint it.
Please advise, thank you

>>but my application still give 'illegal operation' after a few days. I am running win9x system.
>>I am loss on how to solve this issue. Any advise or suggestion
>>is greater appreciated.

>If you are running VFP6 or VFP7, build an exe with Debug Info (in the project information dialog) on. Then the exception dialog will give the call stack, and line of VFP code which is executing, when the fatal expection occurs. With this information, maybe we can determine what is happening.
