Suppose if i have a form A with the field BLOB (having the picture).
If i want to get the same data from the Form A to the form B including the BLOB field. Is it possible. Can anyone give me the solution?

This is a fairly simple & straighforward task and you can use the copystream function (look it up in online help for more details).

Here's some pseudocode that should help you out. (Note that i may have the order incorrect on the copystream function as I don't remember the syntax off the top of my head)

RecordA.calcfields(BLOBField);
RecordA.BLOBField.createoutstream(outsreamVar);
RecordB.BLOBField.createinstream(instreamVar);
copystream(outstreamVar,instreamVar);
RecordB.modify;

Thats how I have been able to get BLOB datamoved around. Should you not have a BLOB field on a record you can always use an instance of the TempBlob table (Table99008535) to work with BLOBs and streams.

Thank you very much for this solution. I have a doubt whether i need to place these coding in Form A or Form B

Whether i need to place these codings in the table level.

Can u able to help me out ?

I would think it would be easiest to place this kind of logic at the table layer. I try to keep forms as "dumb" as possible, and place any logic into a table or codeunit. As you cannot view all of the code in a form (i.e. you an only see the OnClick/OnActivate/OnPush, etc. triggers of the active element) if code is on forms it can be harded to find and fix at a later point.
