ARX add-in wizard does not let me use treeview control

[Anonymous]

I am trying to migrate a VBA project to .Net. I created a new AutoCAD plug-in (from the installed template) and then added a Windows Form. I placed a TreeView control on the form, but VB won't recognize the reference to the control. When I try to Dim a variable as a TreeNode, it tells me "Type 'treenode' not defined. WTH?

If I start a new Windows Form project, I have no problem with this. In fact, I have a seperate VB.Net program I wrote with extensive use of the treeview control. It is only when using the wizard that this happens. The project seems to have all the same references, so I am stumped here.

Any ideas?

Imports System.Windows.Forms
 
Public Class Form1
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim treeNde As TreeNode
    End Sub
End Class

Since you have added a Win Form, so the System.Windows.Forms.dll must have already been refererenced by your project.

In the code file, you need

Either import the namespace:

Import System.Windows.Forms

Or use fully qualified class name:

Dim node As System.Windows.Forms.TreeNode

Thanks. That did it. I probably should have figured that out on my own.
