PSQLQuery1.Params[0].AsString := <put here your query-params, e.g. image-name, record-indentifier> PSQLQuery1.ExecSQL --> what's your requested output (ExecSQL can only output 1 single value) Maybe better use PSQLQuery1.Open;, get whatever field-values you need, then PSQLQuery.Close; DeviceNotebookMouseUpAlias(Sender, Button, Shift, X, Y); Who is the Sender ? Since you are clicking on a TButton, your sender will be the TButton, but your DeviceNotebookMouseUpAlias will only run if the Object is a TImage (if Sender is TImage); Paul van Mil Senior Developer MAD-Systems Burg. van Suchtelenstr. 26 6641 XN Beuningen (Gld) The Netherlands Url: www.madsystems.nl Tel.: +31 (0)24-366 1501 Fax.: +31 (0)24-366 1502 Mob.: +31 (0)6 2251 4084 Email: [EMAIL PROTECTED] ************************************************************************* Disclaimer: MAD-Systems is de enige opdrachtnemer van alle werkzaamheden.
