Your problem is that you are still writing pointers into a file. Write only the data not any address.
Write:

walter clark>form1.h instead of Form1.h
File is compilation unit it is not a programming construct. Is Form1.h or form1.h included in your project?

There is no doubt about it. It has to work.

lost_scotsman,
996 bytes will be the size of binary file. Calculate the size of an instance manually and put it with write & read methods.
