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 was reading about late binding, but I'm not completely sure what is to be
done in order to adjust code to late binding...
For example, I'm not sure if this is correct:
early binding:
Dim ws As DAO.Workspace
Dim db As DAO.Database
Dim qdf As DAO.QueryDef
Dim rs As DAO.Recordset

Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

hi All,
I've decided to use Options Strict ON in one of my apps and now I'm trying
to fix a late binding issue. I have 5 integer arrays:
dim IA1(500), IA2(500), IA3(500), IA4(500), IA5(500) as integer
The integers in these arrays are actually pointers to different columns of
data in a text file.

Is there any way to enable exception throws in VS 2005, that occur during
binding operations?
I am upset that i can't see exceptions that are thrown during binding
operations. It's very hard to track down erroneous behaviour of your app if
you can't see where the problem is... i mean it's realy hard to debug
binding issues and it would be realy of help if i could somehow enable this
during debug session.

The process of verifying that an Object exists and that a specified Property or Method is valid is called Binding. There are two times when this verification process can take place: during compile time (Early Binding) or run time (Late Binding). When you declare an Object Variable as a specific Data Type, you are using Early Binding so the verification can take place during compile time. When you declare a Variable of the generic Object Data...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
