Problem With SQL SQLCECommand - Missing Parameter

Have a nice day. I'm developing for PocketPC using VB2005 and SQLMobile and need some help to solve the following issue:

At runtime the following code throws an exception #25950 SSCE_M_QP_MISSINGPARAMETER

Missing Parameter [Parameter ordinal = 1]

Everything looks fine, but it still fails. In the same app I have a datagrid connected via a dataset and it works OK. Please give me directions!!



Dim conn As SqlCeConnection = Nothing

Try

conn = New SqlCeConnection("Data Source =" & _

(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly.GetName.CodeBase) + "db.sdf;"))

conn.Open()

Dim cmd As SqlCeCommand = conn.CreateCommand

cmd.CommandText = " INSERT t_People ([txt_Name], [txt_LastName]) VALUES ('CLARK', 'KENT') "

cmd.ExecuteNonQuery()

Catch ex As Exception

MsgBox(ex.ToString)

Finally

conn.Close()

End Try
