Issues with OledbDataAdapte r.Update()

Hi

I have a problem with an insert statment using the update() method of the
OledbDataAdapte r.
I'm getting the error 'Update requires a valid InsertCommand when passed
DataRow collection with new rows. '
Heres a condensed version of the page.

<%@ Import Namespace="syst em.Data" %>
<%@ Import Namespace="syst em.Data.Oledb" %>
<script language="vb" runat="server">
Sub Page_Load(sende r As Object, e As EventArgs)
Dim objDataSet As New DataSet()
Dim objDataAdapter As New OledbDataAdapte r()
Dim strConnection As String =
ConfigurationSe ttings.AppSetti ngs("Connection String")
Dim strSQL As String = "SELECT [ppcTerm], [pageName], [contentTitle],
[contentBody] FROM tbl_content"
Dim objConnection As New oleDbConnection (strConnection)
Dim objCommand As New oleDbCommand(st rSQL, objConnection)
objDataAdapter. SelectCommand = objCommand
objDataAdapter. Fill(objDataSet )
Dim objNewRow As DataRow = objDataSet.Tabl es(0).NewRow
objNewRow(0) = "value1"
objNewRow(1) = "value2"
objNewRow(2) = "value3"
objNewRow(3) = "value4"
objDataSet.Tabl es(0).Rows.Add( objNewRow)
objDataAdapter. Update(objDataS et)
End sub
</script>

I'm aware there are other ways of doing this like using an INSERT statement,
but i'd like to know why this isnt working.

Thanks for any help in advance.

Hi,

Although I'm against using datasets (ORM much better), you need to set
objDataAdapter. InsertCommand exectly as you set SelectCommand. Otherwise
the adapter won't know which command to run against changed values in
dataset.

I create 2 data OleDbDataAdapters, one with the wizard, and one in code. I know the adapter created in code is OK because I use it to fill a data table. However, when I try to use the same SQL insert statement in the two adapters, the adapter created with the wizard works fine, but the adapter created in code gives me an error "Object reference not set to an instance of an object". The code is below. What am I doing wrong? ...
