Default Chap 15, Try It Out: Creating RPC Server in asp

Having created the rpc with asp fine i was keen to try accessing the data through vb.net (code on page 567). Firstly i created a vb.net console app, then typed in the code. Expecting the simple app to work i hit play. The following error appears.

"An unhandled exception of type 'System.ArgumentException' occurred in microsoft.visualbasic.dll

Additional information: Argument 'Prompt' cannot be converted to type 'String'."

Can anyone tell me what im doing wrong? the codes in fine, the link to the asp.net page works fine. (works fine as an asp page to)

I think the problems with this line..

MsgBox(xdDoc.SelectSingleNode("/updateTotalResponse/extPrice"))

but im not positive. Any help would be much appreciated.

Hi, my english sucks, so I hope you can understand it

The problem appeared when I tried to move the value of a textbox to one of the parameters of a SQL query, i fixed it by adding a new parameter to the DataAdapter
Lines of code 2 & 3 produced that error. Line 1 was added to fix it.

1. OleDbDataAdapter3.SelectCommand.Parameters.Add("?n umc", OleDb.OleDbType.Integer)
2. OleDbDataAdapter3.SelectCommand.Parameters.Item("? numc").Value = Me.txtBuscar.Text
3. OleDbDataAdapter3.Fill(DsBusqueda1, "qry_condomino")

Suerte ;)

I know this may not help the poster as it's so long since posting but for others...

I don't have the XML to hand but if extPrice is an element like this:
Code:
<extPrice>51</extPrice>
then modify the selectSingleNode to read:
Code:
MsgBox(xdDoc.SelectSingleNode("/updateTotalResponse/extPrice").InnerText)
(I presume the code uses System.Xml)
