Write an object to a File?

[ahhchu]

Can an object be written to a file and then retrieved back into the object or do I have to break it down into appropriate fields in a record and write the record?

Thanks !

I found that using BLOCKWRITE and BLOCK READ on an untyped file seems to work. If it doesnt or causes problems I will put more information here..

f : file;
hFile : integer;
myUserApp : TUserApp;


AssignFile (f,'test');
ReWrite (f,1); //must specify size other wise io err 1784
myObject := TObject.Create;

BlockWrite (f,myObject,512);

myUserAppp : TUserApp

should be

myObject : TObject

oooops

Can write the block but the values dont come back properely.

AssignFile (f,'test');
Reset (f,1); //must specify size other wise io err 1784
myObject := TObject.Create;

BlockRead (f,myObject,512);

Any Ideas ? Thanks
