is dll Registered?

[GaryDean]

not sure this is the right forum for this but I don't know what is...

I inherited an application that has a lot of dlls. Some are unmanaged com
dlls and need to be registered.

How can I tell if the dll is com?
How can I tell if it's registered?

I suggest to take a look at the "OLE-COM Object Viewer" tool coming with
"bigger" versions of VS ("%PROGRAMFILES%\Microsoft Visual Studio
8\Common7\Tools\Bin\OleView.Exe"). In addition, take a look at the "regasm"
and "regsvr32" tools.

If you dependencywalker on them you'll see a DllRegisterServer (or not)
exported.

If you don't have the source to know the relevant guids, you'd use OLEView
to find CLSIDs, or use a tool that spies on registry changes when you run
regsvr32 on them to see what changes are made to the registry.
