Lew,

I was using a dual core cpu based XP system to work with an MS SQL database.
Using both remote views as well as SQL pass-through, I did not encounter this
problem.  The application is in use at locations throughout the U.S. again
without such a problem (although I doubt these installations are using similar
cpus....)

I can offer you two ideas.

1) Try the basic approach of narrowing down the code to the fewest number of
lines that still reproduce the problem.  Just doing this often identifies it.
But if not, post that code and we can test it on our computers.  Unfortunately,
mine is in the shop until 2-20 so I hope others here can help you before then.

2) Does this happen when you are stepping through the code or only during run
time when the debugger is not active? If the latter, I have a debugging tool
that might still help you identify the problem, should you be so interested.

Take care 

Fletcher

Subject: RE: Buffer overruns & stuff

The problem predates SetMemory(), there are no other api calls. This is XP pro.
I haven't tested the difference between app's vs exe's. I'm using apps for now,
but a standalone exe is in the near future. I'll try to see if there's a
particular place or routine that blows up today, but I don't think so.

Yes-- I'm primarily making sure it's created by the VFP process and not
something you're observing through a c++ debugger you've attached to the
process or anything.

You are using API calls in Ed's setmemory.prg. What O/S are you running
under? interpretted and/or compiled?

Have you commented Ed's setmemory.prg to see if that's causing the
issue? I'm curious, considering you're bringing it up-- unless it's the
cause, it shouldn't matter-- a buffer over-run is an error in code and
shouldn't be related to available memory whatsoever.

Have you been able to narrow it down to any part of your code? I've had
many VFP functions with known buffer overrun problems, such as
TEXTMERGE() in VFP7. There was a work-around then that you can pass the
string with a chr(0) at the end(effectively zero-terminating the
c++ buffer properly). I wrote simple Z() and NZ() functions for this
purpose-- adding and removing the trailing nulls..
