I placed 'DBIMAGE'component on my form which connect to DataSource and Datafield and using popup menu I load image from my ClipBoard with follow lines of code in runtime.
        Table1.Open;
        DBImage1.PasteFromClipboard;
But I failed to save that image to my DBF table which got MEMO field inside.
Can anybody help me to save a image to my DBF table(memo field) from my form.

        Table1.Open;
        Table1.Edit;  
        DBImage1.PasteFromClipboard;
        Table1.Post;
If I try to put Edit and Post to above code its giving "Stream Read Error"..

Please help me asap. Thank you.

MEMO fields are only for text.

If you want to save images, use a BLOB field.

since you are using .dbf files, I assume you are using DBase?

Whether or not you can use BLOB fields depends on which dBase version your table is. If you are using a dBase IV table, then you are out of luck.

In dBase for Windows, there is a field type called Binary. To get more info on BLOBs, check out the Delphi help file.

Hi,
 if u have Dbase IV or Paradox then use Deliphi menu Tools -> database desktop to create the table.

HTH ;)

When working with images and databases I allways use to save on the database only the path where the image file is located on my HD, this ensures that my database wont grow too much, and wont get corrupt so often.

Follow this link and download a demo:

Hope it helps!

I agree with VSF about storing the actual image files outside the database.

BTW...BLOB = Binary Large OBject
