What CDO is in use

[MN]

Hi.

When I have both Outlook and ESM from the Exchange 2000 CD installed on a
PC. How do I figure out what
cdo.dll is in use?

If you are asking because of this month's security bulleting on
Collaboration Data Objects, you are actually after CDOEX.DLL and CDOSYS.DLL.
Both of these buggers deal with handling event sinks in the SMTP service.
Do not confuse this with CDO.DLL that handles manipulating items in
Exchange/Outlook folders.

If you are asking because you are writing code that uses CDO.DLL and are
curious to know when the solution runs on a desktop that only has Outlook
2000 (SP2) later because you want to avoid the security prompts, then you
would have to check the registry to verify the path to the DLL file. Once
that is verified, you can bring up the properties on CDO.DLL and see if it
says "Collaboration Data Objects 1.21s for Windows NT" on the version tab.
If the "s" is present, then it is from Microsoft Outlook.
