INTRODUCTION
One of the most powerful aspects of .NET and Windows Forms is data
binding. Data binding is the process of associating user interface
(UI) elements with a data source to generate a visual representation
of data. Two types of data binding are available for Windows Forms:
Simple Data Binding and Complex Data Binding.
Simple data binding allows you to bind one data element to a control.
In many situations you want to display...

Hi .. I have an issue I have been beating my head against
the wall on for some time. I am trying to use late
binding for MS graph so that my end users don't have to
worry about having the right version of the MS Graph type
library. Up until now I have been walking them through
the process of setting the references to include their
version of MS Graph library.
My problem is that I can not seem to get the syntax
correct .. or perhaps...

I have this:
Dim Cbr As Object
Dim Ctl As Object
Set Cbr = Application.Commandbars("CourseCalendarMonth")
Set Ctl =
Application.Commandbars("CourseCalendarMonth").Controls("CalendarMonth")
Is this considered late binding? If not, what needs changed?
Thanks!

I observe a very weird behavior when dynamically create web control
and bind events to it.
Create a C# ASP.NET application,
Put a PlaceHolder and Textbox onto the Web form,
and try with the 4 code scenerio below.

Hi
I have a question about whether Data Binding can facilitate the process of saving data in a web application
I learned that you can data bind information from a number of different data sources to controls such as TextBox, ListBox, etc. I am clear on the concept of data flowing from data sources into web forms controls
What I am not clear about is how to make the data flow the other way. When I am ready to save the changes or add a...

Hello,
I'm trying to use an ArrayList to do data binding, but am getting an
error I don't understand. I posted this in another thread, but that was
all confused with various other problems, which could be why no-one
answered it!! I've now narrowed the problem down, so am starting a new,
more specific, thread. Sorry it's a bit long, but it's reasonably simple
stuff.

In the old days (VB3 era), there was a thing called the Data Control,
and you could use it to databind controls on forms to datasources, and
so (as the marketing speak goes), 'create database applications without
writing a single line of code!!!'. Personally, and I know I wasn't
alone in this, I was always suspicious of this claim, because one
invariably ended up writing huge amounts of code attempting to get the
automagical thing to do...

Here's the scenario:
Show the user a list of Things. User picks one, and the Thing edit
frame is populated with the details of the Thing they picked. This
frame has Save / Discard buttons that are initially disabled. When the
user makes a change to any of the details of the Thing, those buttons
become enabled (because there are now changed to Save or Discard).
So I have a ThingDirty property, and all the xxxChanged events of the
Thing...

I've come across an interesting bug.
I have workarounds but i'd like to know the root of the problem. I've
stripped it down into a short file and hope someone might have an idea about
what's going on.
It's a simple program that loads a control onto a form and binds "Foo"
against a combobox ("SelectedItem") for it's "Bar" property and a
datetimepicker ("Value") for it's "DateTime" property. The
DateTimePicker.Visible value is set to...

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:

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...
