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
basically trying to send an ID variable into sql to return different records.
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
the expanded view):

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

Greetings and salutations! I am having a real issue with the VB.NET
TreeView control. I need to display an image (a.k.a. logo, picture,
etc) from a file as the treenode object. I can not seem to find a way
to do this in .NET. I have tried the DrawImageUnscaled and thought
that was the way to go, but I was wrong. If anyone has any
suggestions, please help! The code I have currently follows:

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

I am trying to add nodes with keys to my treeview. I can add general
nodes without problem with:
//create new node
TreeNode newNode = new TreeNode(myIdNumber);

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
