Setting User Roles Without Using Reporting Manager - Using Setpolicies In Visual Studio VB

I have created an web reference called ReportingSerivce 2005. i am trying to set an user to have browser rights without going into Report Manager.

But I can't get the SetPolicies function to work correctly. Any ideas?

Code written in VB.


Dim rs As ReportingService2005
rs.Url = "https://wa.hrconnect.treas.gov/reportserver/reportservice2005.asmx"


Dim Item As String = "/"
Dim Policies() As Policy
Policies(0) = New Policy
Policies(0).GroupUserName = TxtUser.ToString
Policies(0).Roles = New Role(0) {}
Policies(0).Roles(0) = New Role
Policies(0).Roles(0).Name = "Browser"
Policies(0).Roles(0).Description = "May view folders and reports."
rs.SetPolicies(Item, Policies)
