Hi
Sorry, "as usual" was probably an over-statement. The OP said "It was easy enough to do the old OLE or COM objects," so I assume there is some way to do it with COM objects through Win32::OLE. My experience of late has been to invoke .NET dlls from legacy C apps through COM wrappers. I haven't done this with Perl, but putting it all together (.NET -> COM -> Perl thru OLE ) should work.
