This is a simple class with some methods very useful that allow parsing the URL parameters in many web agents. Class ParseUrl

    Private URL As String
    Private Params List As String
    Private Names As Variant
    Private Values As Variant

    Sub New( sQuery As String)

    If( sQuery = "") Then
        URL = "NULL"
    Else
            URL = sQuery
        Names = Evaluate("@Word(@Explode(@Right(""" & URL & """; ""&""); ""&""); ""=""; 1)")
            Values = Evaluate("@Word(@Explode(@Right(""" & URL & """; ""&""); ""&""); ""=""; 2)")

            Dim i As Integer
            i=0
            Forall v In Names
                Params( v ) = Values(i)
                i = i+1
            End Forall
        End If
    End Sub

    Function getParameter( sParName As String) As String
        Dim value As String

        If Iselement( Params( sParName ) ) = True Then
            value = Params( sParName )
            If value = "" Then
                getParameter = "NULL"
            Else
                getParameter = value
            End If
        Else
            getParameter = "NULL"
        End If

    End Function
End Class

Example:

Notes Agent

(Option)

Use "ClassUrlParameter"

Sub Initialize

Dim session as New NotesSession
Dim docCont as NotesDocument

Set docCont = session.DocumentContext

Dim urlParameters As New ParseUrl( docCont.Query_String(0))

Dim sValue As String
sValue = urlParameters.getParameter( "" )

..........
' <Put here your script >
.........
.........

end Sub

If your Query_String is something like this
"OpenFrom&Cod=10&Tit=Pippo" sValue will be equal to "10".
