Unable to get ContentTreeViewNode by API

[Anonymous]

I am struggling to get the ContentTreeViewNode object filled correctly. I set Category="Fasteners"

Public Class SearchCC
#Region "Properties"
    Dim IU As New InventorUtils
    Private _PartNames As New Collection
    Private _tvNodeTop As ContentTreeViewNode = Nothing
...
...
    'top of tree view to start searching in Content Center
    Private _TopNodeName As String = ""
    Public Property TopNodeName() As String
        Get
            Return _TopNodeName
        End Get
        Set(ByVal value As String)
            _TopNodeName = value
        End Set
    End Property
 
    Private _Category As String = ""
    Public Property Category As String
        Get
            Return _Category
        End Get
        Set(ByVal value As String)
            _Category = value
            If value <> "" Then
                _tvNodeTop = IU.CC.TreeViewTopNode.ChildNodes.Item(_Category)  <---- line 45
            End If
        End Set
    End Property

 I receive the following error:

All examples I can find forward a string as category name, so what am I overlooking here?

I discovered I was able to run the code, in debug mode in VS,  after a full restart of windows. The code ran for several categories and then suddenly halted on the same line with the same error code.

Can there be some kind of overflow of data here? The scan starts from level one ( for example 'fasteners') which runs ok. But when 'fasteners' and  'Tube & Pipe' are done sequential in one run the error pops up again.

Hi Maarten,

This seems similar to this issue:

I made a note in the log that you ran into it as well.

Hope that will raise the priority.

Cheers,
