Uso o seguinte comando:

If OpenPictureDialog1.Execute then
begin

Image1.Picture.LoadFromFile( OpenPictureDialog1.FileName );

if OpenPictureDialog1.FileName <> ´´ then
begin
Image1.Visible := True;

if not ( QryPAR.State in [dsEdit, dsInsert]) then
QryPAR.Edit;

QryParLOGO.LoadFromFile( OpenPictureDialog1.FileName );
QryPar.Post;
[b:09b079c5aa] QryPar.ApplyUpdates( -1);[/b:09b079c5aa]
end;

end;


E me aparece o seguinte erro:

´Unable to find record. No key specified´.

O que fazer??
