Detection/Signature for Corba/Com/Dcom/Activex Modules

[nulli]

First i would like to thank you for taking the time to reading this message! What i would like to know is if anyone has a detection signature for com/com+/.net com/activex/ole/corba type of modules (dll's)? i guess i could for instance check for the presence of 'DllGetClassObject' export from a ole com module, but would like to know if anyone has any links or experience on this subject they would like to share. The reason for this is that im creating some code that doesnt support tracing into com and alike interfaces.

Thanks in advance...
