Hi Experts,

Does anyone know of a tool that tracks COM reference counts? I have a 3rd party DirectShow object that does not clean up properly as well as an (unrelated) ActiveX control that wont shutdown properly, I could do with something that can be constrained to sets of class instances.

Any ideas?

cheers

Dave

The return values from AddRef and Release normally provide an indication on the internal reference counts. Not always accurate though. But if Release was to return 0, it's a good sign that things are Ok.

that is no real tracker though.
you can check the refcount at some points but not monitor it...

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks everyone

I know about the AddRef and Release, if it was my code I would reimplement IUnknown but it's third party so I just wanted a simple utility to check.

I've installed boundschecker (which I haven't used for some years) and will try that.

I totally agree. Just unwilling to spend money.
