Hi All,

I'm working on a project which involves VC++6.0 and MQSeries.

I'm getting an error "User breakpoint called from code 0x77f762e8"  while trying to debug my application.
Ofcourse, I have allocated huge amount of memory from inside my app.

Can anybody please suggest a solution to overcome this ASP?
I have to finish this project at the earliest.

Thanks,
Shobha

You need to examine the Call Stack window,  It will lead you to the part of your program code that caused the error.  To examine the call stack, press ALT+7 when that error occurs.

This is not really a "User breakpoint" but rather an execution error.  If it were a real user breakpoint, the user breakpoint handler would have been called and something more useful would have happened.

This is most often caused by a trashed return value on the stack or bogus function call address.  As DanRollins notes, use the CALL STACK or if that is not working right, run your application in the debugger until you discover where it is going wrong.

I have seen this kind of mysterious breakpoints when linking release-built obj-files together with debug-built ones.

I have no explanation why this happens but it might be a good idea to look through your project settings and make sure you're not mixing obj-files or libraries.
