Hi,

I have a direct reference to a VB6 COM component in my C# application.
During runtime, the methods I call on the COM component get executed
fully and but when returning to the calling .Net component, throw an
ExecutionEngineException.
Can somebody thrown light on when and why an ExecutionEngineException
would occur and how it could be prevented?

Thanks,
Anand

Yikes! That's a nasty one. According to the docs:

"Execution engine errors are fatal errors that should never occur. Such
errors occur mainly when the execution engine has been corrupted or data
is missing."

IS your .NET runtime up-to-date with service packs? Perhaps an
uninstall/reinstall of the .NET runtime might clean things up.
