Subject: Re: save jpg to blob field
In reply to: John Makar 's message, "save jpg to blob field" on 12:48:57 03/30/00 Thu


Hi John,

The simplest way to do this is to use a TBlobStream to access a blob field in your table. This assumes you have a TBlobField in your table or query.

To read from a blob field:

BlobStream := TBlobStream.Create( Table.FieldByName('Image'), bmRead );

ImageScrollBox.LoadFromStream(BlobStream, 'jpg', 1);


To save to a blob stream:

BlobStream := TBlobStream.Create( Table.FieldByName('Image'), bmWrite );

ImageScrollBox.SaveToStream(BlobStream, 'jpg');

Best regards,

Michel
