How to get the real postgreql error from visual basic

Dear Sirs,

when I execute a function that returns an error, visual basic shows always
the same error code ( -214767259) but I would like to know the real postgres
code of the error.

The visual basic code that I use is the following:

Dim Cmd As new ADODB.Command
Cmd.CommandText = "delete from <tablename> where id=<some_number>;"
Cmd.ActiveConnection = mvarConnection
Cmd.Execute

Whichever error appens the visual basic Err object returns the same number.


What I have to do?

Any suggestion will be appreciated.

Domenico
