How we can pass the GUID in the link accurately to the report server

Dears, i have a problem, i have this link and variable passing it to the report server
i want to check if the link is correct or no

Private Sub SaveReport(ByVal vORderNum As String, ByVal vGUID As String)
    Dim webClient As New System.Net.WebClient()
    Dim url As String = "http://e10/reports/report/%Epicor10Test%CustomWork%SalesOrderAcknowledgments%SOForm&rs:Format=PDF&rs:Command=Render&TableGuid=" & vGUID
	webClient.UseDefaultCredentials = True
	msgbox(url)
	'msgbox(vGUID)
	'msgbox("hello")
    webClient.DownloadFile(url, "c:\temp\" & vORderNum & ".pdf")
  End Sub

Are you asking if
"http://e10/reports/report/%Epicor10Test%CustomWork%SalesOrderAcknowledgments%SOForm&rs:Format=PDF&rs:Command=Render&TableGuid="&GUID
is correct?

I think the generic format is:
http://<reportservername>/reportserver?<path_to_RDL><runtime_params>

So maybe something like:

"http://e10/reportserver?/reports/Epicor10Test/CustomWork/SalesOrderAcknowledgments/SOForm&rs:Format=PDF&rs:Command=Render&TableGuid="```

take a look at

Thank you man!
