SYMPTOMS
You create an Outlook COM Add-in and when using it, Outlook stops responding (hangs).
CAUSE
The COM Add-in generated an untrapped run-time error.
RESOLUTION
You must use error trapping to prevent all potential run-time errors from happening.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
There are various scenarios where Outlook may hang if you create a COM Add-in and the code in the add-in generates an unexpected run-time error. This problem is related to how Office programs interface with the Visual Basic run-time, and is therefore a general limitation of the COM Add-in architecture.
To avoid these scenarios, every line of code within your COM Add-in must use error trapping to prevent any potential run-time errors from occurring.
REFERENCES
For more information about how to implement error trapping in your code, please see the Microsoft Office 2000/Visual Basic Programmer's Guide, chapter 8, "Error Handling and Debugging."
