I am attempting to show a specific form using a treeview control, the nodes of which have their tag value set to an instance of the Form I need to show. The code I have in the DoubleClick event works great for the first time I show a form, but after that I get an object disposed exception. As you can see, I tried handling it by resetting the tag, but that didn't work. Is there any way I can show the form more than once without going through a switch statement anytime the exception comes up and resetting the tag to the right type of form? I'd like something nicer looking like the way I show the form.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim fm2 As New Form2()
Dim fm3 As New Form3()
TreeView1.Nodes(0).Tag = fm2

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.

I do have a TreeView inside a splitterpanel-control. After executing the ExpandAll()-Method, a scrollbar appears on the panel and the first nodes are no longer visible, because the panel scrolled down to the bottom-nodes. How do scroll back to the top-nodes programmatically, because I want the user to see the first nodes on the top?

I have finally figured out how to populate the the ListView based on the selected node, but when I am debugging, I click on a node, and the ListView doesn't change. I have to single click twice on the node for it to work. What could be my issue? I have included the code from my sub below.

I am trying to setup a treeview control to display all drives and folders on the PC. So far I can display all drives and folders but the images will not show except rarely. I am using an imagelist with 4 images (index 0-3). The code below is used to load the drives in the treeview control. I have tried using every type of image possible from bmp to png and nothing. I have tried the Appllication.EnableVisualStyles() which I now know isn't needed in vs 2008. I am also having problems with a picturebox in another form that shows nothing but a shadow of the image. I suspect this may be a setting somewhere maybe in vs 2008 but am not able to find one.

I have been working with VB 6.0 for years. I am converting an app that uses treeviews to VB.Net 2008. The way it use to work the tree grid started with a list of the drives on the system. Left click drilled down in the selected drive or directory. Right click would perform an action with the selected drive or directory. In VB.Net it appears you can only select with left click using the AFTERSELECT event. Is there a way to select a node with right click?
View 1 Repliesfor some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)
