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?
