Surviving a COM error

3 posts in this topic

Is its safe to reenter your code after trapping a COM error with a user defined error function? In all of the AutoIt code I've seen so far that catches this condition, they appear to treat it as a fatal error and bail whereas I need to circle back through my code and either try again or take a different path. The docs were not clear on this point for me.

An good example of where this would be handy is making WMI calls under WinPE 2.0 can fail the first time through if it takes the system too long to initialize the WMI provider (guessing that is the problem as all subsequent attempts are successful).

Thanks!

Generally speaking, yes. If you make unverified assumptions after a COM error about the state of variables or automation objects etc, then no, but hopefully you knew that already. AutoIt itself is not left in any sort of inconsistent state after trapping a COM error.

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

Sweet! I was really hoping that was the case. Thanks Dale!
