How to read data from blob field?
My blob field contains memo type of data.

Can i display the value of blob field in a textfield simply by setting the SourceExpr property of the text field to that blob field.

When i open the table eventhough my blob field contains data i am not able to see it. I see that blob field is empty. Is it ok?

    No, it is not possible. You can only show blob as image or export/import it into file and then show it through some external component...

    If the blob is filled with BMP picture, you can show it through PictureBox (see for example the Company information Form)

    If it is text, you must export it into some file (for example some temporary file), this file show to user and after the actions import back...
