Default how to pass a value in this webservice?

Hi,

I made a webservice for fetching data from a database. It works good.
Now i would like to add a parameter to the sql command. The user should enter a value (pcnr) before the data is fetched. I tried to add a texbox but it doesn't work.
How can i do that?
Thanks
Bob

My code:

.....
 <WebMethod()> _
    Public Function pcinfo() As DataSet
        Dim oConnection As OleDbConnection
        Dim pcnr As Integer
        Dim d As OleDbDataAdapter
        oConnection = New OleDbConnection()
        Dim sql As String
        Dim ds As New DataSet

        Dim tb As New TextBox
    pcnr= Convert.ToInt16(tb.Text)

        sql = "SELECT * from pc where pcnr=" & pcnr & ";"
        Dim sConnectionString As String
        sConnectionString = "Provider = Microsoft.Jet.OLEDB.4.0; Data Source = c:\mytable.mdb"
        d = New OleDbDataAdapter(sql, sConnectionString)
        d.Fill(ds)
        Return ds
    End Function
....
