    <p>I'm trying to insert a row into a table I have in Access. The table is named Site and it has two columns, SiteId (AutoNumber) and SiteName (Text). For testing purposes, I grabbed a value from an Excel sheet and attempted to insert the value into the SiteName column with the following code...</p> <pre><code>Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim App As New Excel.Application Dim WB As Excel.Workbook = App.Workbooks.Open("C:\MyFile.xlsx") Dim WS As Excel.Worksheet = DirectCast(WB.Worksheets(2), Excel.Worksheet) App.Visible = False Dim Range As Excel.Range Range = WS.Range("A8") Dim cnn As New OleDbConnection(My.Settings.cnn) Dim cmd As New OleDbCommand("INSERT INTO Site(SiteName) VALUES(@SiteName)", cnn) cmd.Parameters.Add("@SiteName", OleDbType.Char).Value = Range.Value.ToString Try Using cmd.Connection cmd.Connection.Open() cmd.ExecuteNonQuery() End Using Catch ex As Exception MessageBox.Show(ex.Message) End Try End Sub </code></pre> <p>Even if I remove the cmd.Parameters line and just put a straight value like Values('Test') it doesn't make an insert. I get no errors in the code as I perform the command. Why is the value not working? I have verified the data returning from the Excel sheet and that works fine. I just can't get it to insert into the table in Access. The connection works fine as well because if I use this Insert...</p> <pre><code>Dim cmd As New OleDbCommand("INSERT INTO Site VALUES(@SiteName)", cnn) </code></pre> <p>it will tell me that the number of query values does not match the field count or something of the sort.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
