Often we need to make a TreeView with checkboxes that have more than 2
states. Consider for example the TreeView of files and folders in a tape
backup program. If the subordinate nodes of a particular node are partly
checked and partly unchecked, then the node itself has a gray checkmark.
I've hit on a way to do this with pure .NET functions, without using Win32
HitTest. See:

I am relativley new to C#, and I am trying to write code using the compact framework, that will allow a handheld user to hit enter while a treeview node is selected, which will then do something based on that nodes text. I cannot figure out how to write a method for this event for a single node. When I double click on the treeview in design mode, the only function it creates (no matter where I click) is private void treeView1_AfterSelect(...)....

I changed the treeview node text to bold and changed color "successfully".
However, the node text was truncated and when i did a tree refresh the node
formatting was gone. What do i need to do to 1) display the node text
properly after i alter font style and color and 2) keep the node format
change if user refreshes tree.
i've been looking at the node.bounds property to increase the rectangle that
the text is displayed in but what do i...

Hi There!
I'm using VB.NET to create a TreeView application and unfortunately I could
not find "Key" property in Node items of the TreeView.
We used to have "Key" property in TreeView node object in VB6.
What is the equivalent of "Key" property of TreeView node in VB.NET? Has the
property name "Key" has been changed to something else? Or VB.NET does not
support the "Key" property anymore? If so what are the alternatives?

Hello,
In a MDI application, I want a child form which contains a treeview with a
associated form for each node.
If I create a child form, I only can put controls. So I can puta Treeview
control and a user control which represents the form for one node. So I have
the same count of user control than the count of nodes in the treeview.
But I will prefer to have forms, and not user control which play the role of

Hi there,
I've looked around the different groups and still can't figure this
out without resorting to scrappy code............
I want to programtically select and highlight a TreeView node, such
that it looks the same as if a user has clicked it.
I'm aware about the SelectedNode property, but this just seems to
expand the TreeView to show the node in question, but not highlight

Hi,
Lets say I have a TreeView with nodes that represent objects of a
number of different types. Is there a way of associating the Set
method of each object with its node in the TreeView? That way when you
select a node in order to change its associated data, you have easy
access to its Set function.
The way I normally handel this situation is is to create an enum of
all the different types that the treeview contains. I then have a

Hi,
I would like simulate a mouse click on on of my treeview nodes when my
form opens.
for that i was thinking to use the same simple way as under C++ :
SendMessage(TreeView.Nodes.Handle, WM_LBUTTONDOWN,0,0);
but it does not work. i do not get any error message and application
runs normally... just my first node is not selected (clicked).

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:

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
