Hi Hilmar,

Well, my purpose is to an object in a way so that i can restore it with all its functionality as fast as possible. You tell me that the file-size can increase very quickly and that means slowing down the retrieval of the object i think. Therefore it looks like i have to follow your suggestion but it will require more programming.
My thoughts were, if i can store an entire object and retrieve it the same way i don't have to worry about reading and writing every property. You showed a way to do this in an easy way and is for me a good solution.
But i am still curious if an object can be stored and retrieved in a general field. If it can be done, i can compare the performence of both methods to see which method delivers the best way to do it.

Thanks for your helpful advice,

Erwin
