[python-win32] Python Windows Scripting Engine

Thu Aug 1 16:37:46 EDT 2024

Hello Mark.

Sorry for bothering you again. I got another issue. When I call
IActiveScript method: SetScriptSite(IActiveScriptSite site)
I got invalid cast exception. Mostprobably it means that
IActiveScriptSite  can't be properly passed as argument to  SetScriptSite.
 My assumption that  my definition of IActiveScriptSite  is different from
one is used in py2in32 library.
I could find usages of   IActiveScriptSite   interface in the source code
of the library. But I can't find definition of this interface.
Can you advise me where I can find it?
