I wrote a Custom Search method (GetSearchItems) in my Controller class and it works fine on my desktop computer where I do development.  On my hosted dedicated server, the site works fine but the code in the Custom Search method is having trouble getting the PortalID. Below are the relavant lines of code. The line "Dim thisPortalID As Integer = thisPortal.PortalID" throws the exception.

'Imports

'Class declaration
Public Class MyController
        Implements Entities.Modules.ISearchable
...
'Custom Search Method
Public Function GetSearchItems(ByVal modInfo As Entities.Modules.ModuleInfo) As SearchItemInfoCollection Implements Entities.Modules.ISearchable.GetSearchItems
            Dim searchItems As New SearchItemInfoCollection
            Dim item As HSStyleMasterInfo
            Dim controller As New HSStyleItemController
            Dim items As List(Of HSStyleMasterInfo) = controller.GetStyleMasterItems("ActiveStyle = 1")
            Dim limit As Int16 = 100
            Dim thisPortal As New DotNetNuke.Entities.Modules.PortalModuleBase
            Dim thisPortalID As Integer = thisPortal.PortalId
...

That was it Cathal.  Not sure why the previous code worked on my development station, but using the ModInfo.PortalId closed that issue.  Thank you very much for your quick response.  That and about 4 more bugs later and my custom search is working on the server.
