Difference between aspx and vb.net

[donstephens]

I'm trying to create a aspx page and had assumed that I could plug in my vb.net code.

I have a function that parses Homeseer events in vb.net that works but chokes when I try it in aspx. (Thanks Adam for heads up on the vb.net part)

Public Function getEvents()

    Dim cnt As Integer = hs.EventCount
    Dim arrEvents() As String
    Dim i As Integer = 0

    If cnt > 0 Then

        Dim evntGroups As strEventGroupData() = hs.Event_Group_Info_All()
        For Each evntGrp As strEventGroupData In evntGroups

            Try
                Dim evnts As strEventData() = hs.Event_Info_Group(evntGrp.GroupID)

                For Each evnt As strEventData In evnts


                    If evnt.GroupName = "XM Radio" Then
                        ' hs.Writelog("Test", evnt.GroupName & "   " & evnt.Event_Name)
                        ReDim Preserve arrEvents(i)
                        arrEvents(i) = evnt.Event_Name
                        i = i + 1
                    End If
                Next
            Catch ex As Exception
                '            'ProcessError(plugin.instance, ex, "SlimServerXML - GenPage()")
                '            hs.WriteLog("Opps", ex.message)
            End Try
            'Return Nothing
        Next
    End If
    Return arrEvents
End Function 

If I try to use this function in an aspx page I get the following error.
Type 'strEventGroupData' is not defined.

Here is the line that is causing the problem.

Dim evntGroups As strEventGroupData() = hs.Event_Group_Info_All() 

Anyone run into this? I'm assuming that I have to declare strEventGroupData but the help page indicates that the return is a type structure. Don't know what that is. This works in a scripting environment, so I'm assuming that I have to declare something that I'm missing.

Thanks

Don,

In vb.net scripts, Homeseer puts a wrapper on the script that you don't see, and it establishes the hs class in your script, so that you can just do hs.whatever and it works.

In ASPX (at least in the HS2 version, which is the only one I know), you need to do it yourself. So in your getEvents() function, just insert this line near the top:

Dim hs As Scheduler.hsapplication = Context.Items("Content")

My guess is you will be fine then.

Hi Steve:

Thanks for the quick reply.

I have this on the top of my aspx page.

    Dim hs As Scheduler.hsapplication
    Dim plugin As HomeSeerAPI.PluginAccess

 hs = Context.Items("Content") 

I'm assuming this is the hs3 version of that.

I'm pretty sure all variable values are not preserved between events in an ASPX page, so you may have to put the hs = into each sub / function in your page. Try just inserting that line into the routine that is failing.

Still no go....

[stevea]

I just realized I was giving you bum information anyway. I thought the reference to hs was failing, but you clearly said it was the class type you were declaring.

Since I don't know anything about HS3 I am not sure what reference you need, but I would be you need some sort of IMPORT, like

<% IMPORT namespace="some homeseer library" %>

Thanks, I'll take a peek at Scheduler in the Object Explorer and see what I see.
edit:

You called it Steve. The missing code was <%@ Import Namespace="HomeseerAPI" %>

Thanks for your help.
