Hmmm - I guess that is a bug in pywin32 - that variant type *is* valid in a
TYPEDESC, so pywin32 probably should convert that during the makepy process.

Can you please try changing the 30 there to 8 (ie, changing from VT_LPSTR to
VT_BSTR) and let me know if it works?

Actually, better yet - if it *does* work, please open a new pywin32 bug at
sourceforge.  If it *doesn't* work it may point at an error in the COM
object.

It is the first string arg that is causing the problem.

Thanks,
