Hi all,
I have read a lot of postings and web pages about drag and drop
and treeviews, but could not find an answer to my problem. Sorry, if I
missed something.
I am trying to drag and drop treenodes defined by myself and
don't understand, how to get the nodes data in the dragdrop event.
I'm not very experienced in .NET and for sure there is a simple solution.
I've written a short sample program, based on well known examples,

Is there a way to store a unique numeric identifier (say, for example,
an int) into a TreeNode, so that when the TreeNode is checked (since
CheckBoxes is enabled) the eventhandler AfterCheck() can examine the
responsible Node's identifier to see which TreeNode triggered the
event? Analyzing the Node's Text string is undesirable because it
would mean performing a string compare to a set of predefined strings.
This is slower and not easily...

Article 311318, "HOW TO: Create a Key Property for a
TreeView Node in Visual Basic .NET". Explains how to
extend the treeview (and treenode) classes to include a
node Key. However, to obtain a node reference, you must
still either use the index, or use a for each ... next
loop in you code to get it by key. I would like to use
the node's key or index interchangeably. To do this, I
think I need to change the treeview's Nodes property...

Hello everyone.
I own two books. Learning Python and Python in a nutshell. When cross
referencing the two books to try and clarify the ideas behind extending
methods and delegates, this is where confusion veered it's ugly head :(
Learning Python explains on page 324: Class Interface Techniques
(21.3.3 in the ebook) the following is an extender method.

Hi People
Could anyone suggest to me the best way to distinguish treenodes? By
this I mean I'm in a situation where I have a TreeNode that displays a
number of categories and within those nodes there are items of stock.
There are a number of things I wish to do, such as use a ContextMenu to
Rename the node, but I can't seemingly tell if the Node I'm renaming is
a category or an item of stock.

Hi,
We are working on a vb.net WinForms project based on the Composite UI
Application Block (VS2005). I have a strange problem. At first, I
thought 10 minutes would be fairly enough for me to solve it but I've
spent almost 6 hours on it today and still can't figure out what's
wrong.
Using the CAB, I have built a control that intercepts messages coming
from other CAB's SmartParts controls and display them into a treeview
control. The...

My first time using a TreeView:
I've got a TreeView that I populated with some data and it has nodes.
In the Properties window, I created an Event Handler for the TreeView's
AfterSelect method, and it allows me to determine what Tree Node has been
selected.
However, if I expand the TreeView and select one of the Child TreeNodes,
they do not trigger this event.

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,...

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...
