created a custom class that is derived from TreeNode, let's call it
customTreeNode. I'm trying to use the TreeViewEventArgs (for the
AfterSelect event) but I cannot cast to my derived TreeNode. Here is
a snip...

Hi. I am trying to enter a variable in the treenodesrc of a treenode. I am

I've searched everywhere and cannot find the answer. I'd appreciate and help.
Thanks.
What I'm doing is creating a treeview with the structure as follows (this is

Hi,
When I implement the example code it errors with
'No parameterless constructor defined for this object.'
experimenting with dim o as object = mytreenode.clone() gives the same
error.
The example code is:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click

Hi,
I have a treeview which contains nodes of a class (classA) derived from
treenode.
These classA nodes may contain nodes of a class (ClassB) derived from
classA.
The form load populates a imagelist and calls a subroutine that assigns an
image to each node depending on its type.
If I expand a classA node, all is well. ie. I see the classA image on the
classA node and the classB image on the exposed classB node (which is always

I am writing a Window app that has a TreeView control. I am creating the
nodes dynamically from an XML file, and I have some icon images that I have
associated with each of the "top" nodes. The users, after some usability
testing, have decided they don't want the "child" nodes to have any icons
associated.
I cannot seem to get the child nodes to NOT have an icon. I have tried

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
