Ado .net Insert Into [resolved]

[CVMichael]

I have problems with the folowing code, and I don't know what's wrong with it...

Dim connString As String = "Provider=Microsoft.Jet.OLEDB.4.0;data source=" & Server.MapPath("ProjectDB.mdb") & ";"
Dim cn As OleDbConnection
cn = New OleDbConnection(connString)
cn.Open()
 
Dim sql_ins As String = "INSERT INTO t_user (userid, username, password) VALUES (2, 'test', 'some password');"
Dim cmd_ins As OleDbCommand
cmd_ins = New OleDbCommand(sql_ins, cn)
cmd_ins.ExecuteNonQuery()

If I try to do select statements, it works fine, I can retreive the data, but it does not work for insert...
