How do I correct the error message "c++ event sink - failure to unadise"?

Answer 1

Set your debugger to checkpoint on error and dispatch a thread to write a suicide note on process rundown.

If you are calling an active-x object written in VB, then see this link:

You need to see the machine instruction being executed which will also point back to the line of C code that it belonged to, as well as the state of the system at the time of process rundown. The suicide note will give you the system data structures and kernel code that was also running at the same time. This can be a hard error to debug so put on your checkered hat.
