Com Object Exception

Question

I wrote an application that loops through a set of records and prints two things.

One is a report from SSRS wich works correctly.

The other is a drawing that uses a COM object to print. The COM object randomly fails and causes the program to quit.

Is there a way to stop it from killing the entire program when the COM Object fails? I have tried catch every exception at every level and it still does not work.

Answer 1

Do you have the code of COM object that you are calling. If you have code then check whether there any exit command on failure.

Answer 2

Are you using the COM object from multiple threads? You should only access the COM object from a single thread with a message pump. In my experience this can cause weird instability which cannot be trapped via a try-catch.

Answer 3

It sounds like the issue maybe with the com object itself and not your code. If this is the case then if the com object does not throw an error then you will not be able to catch one.
