DBImage?

by Nura » Sun, 31 Dec 1899 09:00:00

I am linking a DBImage component to a Microsoft Access Tabel. The field type
is "OLE Object". In Access, I insert a "bitmap image" object in the field
that is referenced by the DBImage component in Delphi. But DBImage does not
accept this as a valid entry. What is wrong?

Is there anyway that I can embed bitmaps into Access, and view them in
delphi?

1. DBImage can't display JPEG

Hello, everyone !!

I try to display JPEG format pictrue with TDBImage from TBlobField,
then Error Raises (Bitmap image is not valid) !!
I try to do this with coding, but get failure again!!

the failure coding as bellow :

A. with TMomoryStream >>

var msA: TMemoryStream
msA := TMemoryStream.Create;
TBlobField.SaveToStream(msA); <--- EAccessViolation
Image1.Pictrue.Graphic.LoadFromStream(msA);

B. with Clipboard >>

Clipboard.Assign(DBImage1.Picture); <-- Invalid clipboard format
Image1.Pictrue.Assign(Clipboard);

Can you tell me how to display then JPEG Field with TDBImage or TImage ?
Thanks you very much.
