Count records using a wildcard...

I am trying to setup a Count routine that will use a wildcard to find all records in a certain field within a certain table that starts with a specified number (comes from a text box) but I don't think the wildcard is working because no matter what I enter it doesn't find a Count (always 0). Any idea what I might be doing wrong now?

thanks in advance for any help that you can give me with this.

Also tried...
cmd.Parameters.AddWithValue("@CurrDepart", OleDbType.VarChar).Value = Me.txtCurGL.Text.ToString & "%"
'Check to make sure the Current Department already exisits

            Dim Count2 As Integer = 0

            Using Connection As New OleDbConnection _

             ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Comet 631 Databases\Converted to 2003\C022008.mdb")

                Dim cmd As OleDbCommand = New OleDbCommand _

                ("Select Count(ActAcct) as ExistingRecords From [SHACT] where (ActAcct)= @CurrDepart", Connection)

                cmd.Parameters.AddWithValue("@CurrDepart", Me.txtCurGL.Text.ToString & "%")

                 Connection.Open()

                Count2 = CInt(cmd.ExecuteScalar)

                ("@CurrDepart",me.txtCurGL.text.Tostring & "%")end withconnection.open()

            End Using

            'if the Current Department doesn't exisit then throw message and exit sub

            If Count2 <= 0 Then

                MessageBox.Show("The GL Department " & Me.txtCurGL.Text.ToString & " does not exisit.", _

                "Copy Department", MessageBoxButtons.OK)

                Me.txtCurGL.Focus()

                Me.txtCurGL.SelectAll()

                Return

            End If

You can do:

"Select Count(ActAcct) as ExistingRecords From [SHACT] where (ActAcct) Like @CurrDepart"

And the "%" might need to be "*". (Not sure; I don't recall the syntax).

You might also need single quotes. I'd eliminate the parameter and try this directly:

"Select Count(ActAcct) as ExistingRecords From [SHACT] where (ActAcct) Like '" & Me.txtCurGL.Text & "%'", Connection)

Thank you very much nexusnation, "Select Count(ActAcct) as ExistingRecords From [SHACT] where (ActAcct) Like '" & Me.txtCurGL.Text & "%'", Connection) was the answer. I had tried this but had a typo in it so it gave an error and I tried the Paameter instead. But this worked like a charm, thanks again!!
