Parameterized Query in Distributed Application (winform)

Question

I've created the following distributed application: Solution EDSQLWSVC EDEmployerWinClient Project3 Web Service winform app asp.net web app My web services are fine....and I can get data in, out etc. My problem is this: I want to use the data adaptors in the web services for the windows client application. Only problem is...when i want to run a parameterized query in the client application...I get errors flagging the SQL Statement and the Parameterization. Big ones. SO...How do I parameterize the query? I've done it in the Data Adaptor's SQL Statement in the web service, and on the windows form, I've tried: Private Sub GetRecs_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetRecs.Click Dim ws As New EDEmployerWinClient.EDEmployerService.EmpService ws.Credentials = System.Net.CredentialCache.DefaultCredentials EmpRecData.SelectCommand.Parameters("Param1").Value = Textbox1.Text EmpRecsDa1.Clear() EmpRecsDa1.Fill(EmpRecsData) EmpRecsData.Merge(ws.GetRecs()) End Sub EDEmployerService is the web reference, and EmpService is the Web Service All I want it to do is to Select only the records based on the Parameter. In my SQL Statement, I have "SELECT Tbl_One.* FROM Tbl_One WHERE Email = @Param1" This is my first time trying to parameterize a SQL Statement through web services..so I'm a bit lost. Any ideas where someone's done something similar?
