pq12602.zip  DEREFERENCING OCX PARAMETERS USING THE MICROSOFT LISTVIEW CONTROL

The parameters for the OLE event handler methods of drag
drop are passed by reference.  The VisualAge OLE support converts 'by
reference' parameters to instances of OSUInt8.  Therefore, the values
of these pointers must be dereferenced.

When sending messages to the derived DataObject, we encountered the
OLE error 'OLE Automation Error 2147614736'.  The 2147614736 error
indicates a 'DISP_E_BADCALLEE' error.

This problem was subsequently resolved with an updated ocx from microsoft.  
That ocx is version number 5.01.4319
