fill textbox from sql database using a parameter

[srice]

I'm trying to populate my textboxs with data from my database when the user name is selected but I'm having trouble getting the code right. Help Please!
table
users (there is a textbox for each of these fields)
password
lastname
firstname

Using upcmd As New SqlCommand("SELECT * FROM users WHERE userid = @userid", connection)
upcmd.Parameters.Add(New SqlParameter("@userid", Me.txtuseridprofile.Text))
upcmd.Connection.Open()

Try
upcmd.ExecuteNonQuery()
Catch ex As SqlException
If ex.Number <> 0 Then
ErrorProvider1.SetError(Me.txtuseridprofile, "Login Id: " &
Me.txtuseridprofile.Text & " :Not Found!")
upcmd.Connection.Close()
Exit Sub
End If
End Try
upcmd.Connection.Close()
MessageBox.Show("Login ID Found. Update data and Click Go!")

Thanks in advance!

What kind of error do you get? What happens when you run the code?

i think ExecuteNonQuery is not it, because it returns no data rows but instead, ..the number of rows affected !!

here's a code suggestion

Using upcmd As New SqlCommand("SELECT * FROM users WHERE userid = @userid", connection)
            upcmd.Parameters.Add(New SqlParameter("@userid", Me.txtuseridprofile.Text))
            upcmd.Connection.Open()
            Try
                Dim dr As SqlDataReader = upcmd.ExecuteReader()
                If dr.Read Then
                    password.Text = dr.Item(1)
                    lastname.Text = dr.Item(2)
                    firstname.Text = dr.Item(3)
                Else
                    MessageBox.Show("Login ID NOT Found !")
                End If
            Catch ex As SqlException
                If ex.Number <> 0 Then
                    ErrorProvider1.SetError(Me.txtuseridprofile, "Login Id: " &
                    Me.txtuseridprofile.Text & " :Not Found!")
                    upcmd.Connection.Close()
                    Exit Sub
                End If
            End Try
            upcmd.Connection.Close()
            MessageBox.Show("Login ID Found. Update data and Click Go!")
        End Using
