Delphi 2010 mysql picture blob field TUniDBImage Bitmap is not valid

[Astrolab]

It is Delphi2010,mysql(devaart unidac) configuration,

I put tUniDBimage on form ,

set datasource,

and when i set datafield which is image-blob field from TUniQuery

it shows error "Bitmap is not valid".

next code works with tUniImage component,but i want do it with tUniDbImage.

 

procedure TMainForm.UniDBGrid1CellClick(Column: TUniDBGridColumn);

var

JpegImage: TJPEGImage;

BlobStream: TStream;

begin

with UniServerModule do begin

if (not UniQuery1.FieldByName('picture').IsNull) then

begin

BlobStream := UniQuery1.CreateBlobStream(UniQuery1.FieldByName('picture'),bmRead);

JpegImage := TJPEGImage.Create;

try

JpegImage.LoadFromStream(BlobStream);

UniImage1.Picture.Assign(JpegImage);

UniImage1.Visible := True;

finally

JpegImage.Free;

BlobStream.Free;

end;

end

else

UniImage1.Visible := False;

end;

end;

This is an old Delphi one

 

So it works in VCL ?

 

Be nice to have it working directly with jpg and others.
