Load image from DBGrid into a DBImage

[dmarnerou]

Hi,

I have a DBGrid which gets information from an ADOTable. I want to select a row from the DBGrid and when I press the button Show Image I want the selected image to appear in the DBImage field. So basically i want the source code behind the Show Image button I am working with *.bmp images.

Thanks,
Demetra

As you navigate through a DBGrid, you are moving the cursor of the linked TDataSet. If you link the DBImage to the same DataSet (e.g. by using the same DataSource as the DBGrid), it will automatically synchronize.

At that point, it is just a matter of showing the DBImage or not (you might want to wait until the Show button to minimize the amount of data moved over the network).

Cheers

What happend when you tried?

Did the image just not appear or did you get an exception?

Cheers

If you use

TBlobField(DBGrid.DataSource.DataSet.FieldByName('IMAGE')).SaveToFile(AFileName);

, do you get a valid BMP file?
