We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

Subject: Invalid offset into the BLOB - AGAIN - Correction

I have placed a wrong example - the first - in the previous posted letter. That is the correct variant of the procedure.

procedure TMain.aLoadShemaExecute(Sender: TObject);
var
Stream: TBlobStream;
Graphic: TTiffGraphic;
begin
with OpenPictureDialog1 do
if Execute then
begin
ImageShema.Picture.LoadFromFile(FileName); // Only tiff files (ImageShema: TImage)

with DataModule1.tblTree do
begin
Edit;
Stream:=TBlobStream.Create(FieldByName('Picture') as TBlobField, bmWrite);
Graphic:=TTiffGraphic.Create;
Graphic:=ImageShema.Picture.Graphic as TTiffGraphic;
Graphic.SaveToStream(Stream); // Here raise the error
Post;
Graphic.Free;
Stream.Free;
end;
end;
end;
