>when the COM object is ready with getting and parsing the data they should write it to the cursor or return it over parameters to a method of an vfp object which then updates the cursor, in return the object should automatically pass another ID, IP and Port to the COM object if there are any servers left in the "serverpool" .. and so on until the there are no more servers which needed to get updatet .. and then destroying all the COM Objects

You're not gonna be able to read out of a VFP cursor from your C++ com object. You could lookinto using a different way to communicate, like passing XML back and forth, or ADO record sets. If you wanted to be super simple, you could use an INI like or flat text file on disk.
