win32com\src\univgw_dataconv.cpp needs to learn about the VT_RECORD type. PyRecord.cpp contains a function:
BOOL PyObject_AsVARIANTRecordInfo(PyObject *ob, VARIANT *pv)
which oleargs.cpp uses to convert records in the IDispatch case. This function fills the 'pv' element of a variant - you may like to refactor this into 2 functions - one to give the raw pointer and one to set the pointer in the variant. On the other hand, it may be that 'pyrec->pdata' is all you need to pass - I'm not sure how records are passed to vtable based functions. Let me know if that makes sense...

I try use win32com for realize interface: [code lang='IDL'] ... typedef [...] struct tagMatrix3d { Point3d RowX; Point3d RowY; Point3d RowZ; } Matrix3d; ... interface ILocateCommandEvents : IDispatch { ... HRESULT LocateFilter([in] _Element* Element, [in, out] Point3d* Point, [in, out] VARIANT_BOOL* Accepted); ... }; ... [/code]
I'd made it in such way: [code lang='python'] class LocateCommandEvents(object): _com_interfaces_ = [IID_ILocateCommandEvents] _typelib_guid_ = '{CF9F97BF-39F2-4B8E-835C-8BE9E99DAF5B}' _typelib_version_ = 8, 0 _typelib_lcid_ = 0
_public_methods_ = [] _dispid_to_func_ = {..., 0x60020002: 'LocateFilter', ...} def LocateFilter(self, Element, Point, Accepted): print 'LocateFilter' print Element, Point, Accepted return S_OK, None, True ... [/code]
Now errors occur in calls to LocateCommandEvents.LocateFilter function from MicroStation: [code] LocateFilter <win32com.gen_py.Bentley MicroStation DGN 8.0 Object Library._Element instance at 0x12737352> 2223916 True pythoncom error: Failed to call the universal dispatcher
