im trying to assign a value taken from the primary key field and increment it by one to use in an insert

Dim z As Integer
Dim max As String = "select z = MAX(c_msg_nr) from tb_orig_msg"
Dim cmd1 As New SqlCommand(max, oSQLConn)

Yes. :)

You've declared z as an integer, then tried to assign it inside the sql query string. You need to look at ExecuteScalar.

resolved thanks mendhak
ive had some serious trouble with this
genious

my code if any ever has a similar problem

Dim z As Integer
Dim max As String = "select MAX(c_msg_nr)+1 as z from tb_orig_msg"
Dim cmd1 As New SqlCommand(max, oSQLConn)
cmd1.ExecuteNonQuery()
z = cmd1.ExecuteScalar().ToString()


thanks again

Btw, You don't need this line:

cmd1.ExecuteNonQuery()

Why did you include it?
