I'm trying to see the advantage of using "simple data binding".
Let's say I have a treeview loaded from a collection called moList.
On form load, the treeview is loaded. And I bind my textbox to one on the
property
txtLength.DataBindings.Add("Text", moList, "Length")
On the TreeView1 click event, I add the following line :

Ok,
so, say I have a database table with a text field and an ID (key)
field, perhaps like manufacturer and manufacturerID
Now using a dataadapter etc I can pull the data into a dataset/table
I can then use a tree view for example to display this information
mainly because each node can have a TEXT and a TAG value, so i can set
the text to the manufacturer name from the database and the TAG to

Hello,
When building a Microsoft.Web.UI.WebControls.TreeView with multiple
XML files, all of the databound nodes of the tree are not loaded at
once. When the TreeNodeSrc property is set for a TreeNode element, the
contents of the node aren't actually bound to the XML source until the
node is expanded.
So, if the expanded node is bound to its data source(have TreeNodeSrc
attribute) all its children are downloaded and rendered.

I posted this to the vb.data group, but have had no luck. I'm still very
stuck on this problem...it seems the DataBinding works perfectly the first
time an instance of the form is created. The instance is then destroyed and
a new one is opened and positioning the CurrencyManager in the attached code
fails, with no apparent reason. Any help, even just a general direction
where to look is greatly appreciated. Typing in the specific error...

I noticed that the checkbox property is not available in the databindings
editor for the treeview. Does that means that is not possible to databind
the checkbox property to an attribute in the xml file? Or perhaps it would
work creating the databindings programmatically?
Thanks a lot.

I am trying to populate a TreeView with XML data within a DataSet. I don't
see the property DataSource in the treeview, only a DataBinding. Can that
property to be used to populate my TreeView or must I brute force my way by
added each row of my dataset to the TreeView?

Thanks,

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
Here is the code in...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

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...
