I used the LoadTypeLibEx to open a COM type lib. This returns a UCOMITypeLib
interface, which when coupled with the Marshaller namespace can get you lots
of info. My problem is that I don't know what to use to get the version of
the type lib.

Is it buried in the LibAttr structure? Or is there a unique GUID that
translates to 'version'?

I am also trying to find the disk local of the loaded typelib. I figure I
have to look this up myself.

Hi

I think we can go through the TYPEATTR structure to get the version.

Visual Basic, C#] The following example demonstrates using PtrToStructure
after calling UCOMITypeInfo.GetTypeAttr to obtain a TYPEATTR structure.
GetTypeAttr is defined with a by-reference IntPtr parameter because the
unmanaged signature's TYPEATTR** parameter is not supported by the interop
marshaler.
Marshal.PtrToStructure Method (IntPtr, Type)
