------- Additional Comments From rob@codeweavers.com 2006-12-01 18:27 ------- I suspect you mean you get the error 0x80020005 - DISP_E_TYPEMISMATCH.
I am guessing it is the same issue that I've already been made aware of - the app passes in VT_VARIANT to ITypeInfo::Invoke and we are expected to convert it to VT_VARIANT|VT_BYREF. Of course, without any debug error messages to go on, I am just guessing...
