Passing Parameters To Agent With Querystring

When working with Webpages, sometimes you want to pass parameters to agents in
order to process documents.

Here is an easy way to pass parameters with the OpenAgent command and the
QueryString Field.

To test the Code snippet just enter the url like the one below (The parameter
data will be printed back to your browser):

http://server/database.nsf/agentname?OpenAgent&Data1=Param1&Data2=Param2

Sub Initialize
Dim nsession As New NotesSession
Dim doc As NotesDocument
Dim Params List As String


' Get the Web Document
Set doc=nsession.DocumentContext

' Get the Query String Field
args=doc.Query_String(0)

i = Instr(args, "&" )
Do While i>0
args = Mid(args, i+1)
i=Instr(args,"=")
If i>0 Then
' Get the Variable Name
varname = Left(args,i-1)
Else
Exit Do
End If
args=Mid(args, i+1)
i=Instr(args,"&")
If i>0 Then
' Get the Value
value = Left(args, i-1)
Else
value=args
End If

' Save the Parameter in the list
Params(varname)=value
Loop

' Use the parameters

Print "Data1 = " & Params("Data1")
Print "
"
Print "Data2 = " & Params("Data2")
End Sub
