AccessViolationException when profiling

slaneyrw

I'm getting the following exception when trying to profile an application that connects to TeamFoundationServer.

Exception : AccessViolationException
Message : Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I have got an updated ANTS Profiler core2.dll that I can send which is designed to fix one particular cause of this exception. Can I zip up a dll and email it to the address in your profile?

Thanks!

slaneyrw

yes please.

It's on the way!

Is it possible for me to get the new DLL?

I've got the trial version right now, but I am getting the error when I try to run the performance profiler in Detailed Mode. It works fine in Fast Mode, but errors in Detailed Mode.

Thanks!

Hi Ryan,

I've emailed you information about the patch.

I also just downloaded 3.1 as a trial to see if this specific error which I was getting in my registered version of Ants 2 would go away with the new version. Unfortunately it didn't, so I would like to receive info about the patch as well.

Thanks,
Coen
