I have the following set of code for a Sub program. It's inserting a row into a MSAccess Database using data provided in the containing form. What I would like to do is grab the ID number of this added record so that it can be set for a property of a window that is invoked when successfully added. I tried looking this up but I get something about @@IDENTITY
but it's using an entirely different way of connecting.
Private Sub CreateTournament_Click(sender As System.Object, e As System.EventArgs) Handles CreateTournament.Click
' TODO: Check the form for errors, or blank values.
' Create the tournament in the database, add the values where needed. Close the form when done.
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
Dim dr As OleDbDataReader
Dim icount As Integer
Dim str As String
Try
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='C:\Master.mdb'")
cn.Open()
str = "insert into Tournaments (SanctioningID,TournamentName,TournamentVenue,TournamentDateTime,TournamentFirstTable,Game,Format,OrganizerID) values(" _
& CInt(SanctioningIDTxt.Text) & ",'" & Trim(TournamentNameTxt.Text) & "','" & _
"1" & "','" & EventDateTimePck.Value & "','" & TableFirstNumberNo.Value & "','" & GameList.SelectedIndex & "','" & FormatList.SelectedIndex & "','" & Convert.ToInt32(ToIDTxt.Text) & "')"
'string stores the command and CInt is used to convert number to string
cmd = New OleDbCommand(Str, cn)
icount = cmd.ExecuteNonQuery
MessageBox.Show(icount)
'displays number of records inserted
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
Me.Close()
Dim n As New TournamentWindow ' Open a new Tournament window if everything is successful
n.TournID = Counter '<< This should be set to the ID of the most recently inserted row
n.Show(HomeForm)'Invoke the form and assign "HomeForm" as it's parent.
End Sub

Assuming you have an auto increment column in the Tournaments table, you can do a "SELECT @@IDENTITY" to get the id of the last inserted record.
BTW, is the SanctioningIDTxt.Text unique? If so, can't you use that?
