Of course, this presumes the IPersistFile interface was implemented in the COM object. If so, you can a reference to it using the new GetInterface() function in VFP 7.

The OLE Viewer that comes with Visual Studio 6 can be used to interrogate the COM object and see if the interface was implemented.

>>It was not the thing i was looking for. Just as one can store an array into a memo-field i would like to store an object in a table. The object i like to store is created from a COM-object written in java. Instead of creating an empty object for every instance i would like to review it would be much simpler to retrieve the object from a table. I understand that it has something to do with "State".
