Hello All,
In two different books, Simple Data Binding to a control is explained
with an example of a TextBox where the data is initialized with an
array.
For example a class is defined as such:

I have created a query that examines qarterly sales for 5 regions in
the country. The query contains data for the past 6 quarters for each
region and calculates the perecentage of total sales for the quarter

current sales to previous quarter sales and a comparison of current
sales to sales a year ago. I am having a devil of a time creating a

I have looked and searched. What good is the databind property on
Radiobuttons? How does one go about actually using it? What is a good
resource on this? I understand that I can easily get/set the information I
need programmatically, but what about the databind property I just don't
understand it's value.

I'm not sure if I'm going down the correct route...
I have a class which exposes a number of properties of an object (in this
case the object represents a customer). Can I then use this object to
databind to text boxes etc?
I can't use a dataset as the object has loads of derived logic, for example
updating one property may actually update several database fields for
example.

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.

I have noticed that as one adds related tables to a bindingsource and
dataset(vs2005 Vb.Net Sql Server 2005), the TODO and following code that
fills the datasets on form load are written to the formload event in the
order in which you drag the tables to the form to make a gridview, the last
table you drag is written to the top. Since you normallly start by dragging
the parent table and then the child tables and grandchild tables, what...

Hello
I've created a form with 2 listboxes. Both have data-binding. First one
is "normal", 1:1 view of table. Second is filled using parameter from
the first one.
this.xxxTableAdapter.Fill(this.mainDataSet.XXX,
(int)this.BindingContext.Current);
When I do it in Form_Load() it shows first listbox with element with
"id" of value 2 selected, but this.BindingContext.Current == 1. When I do the same thing in

Folks, I am reading/writing data within an XML file. In my form I have a
label that is assigned to the UpdateDate field within the XML file. Within
the form I update the label to a different date. The code is below. The
issue I'm having is that the DataBinding doesn't seem to be behaving
correctly. The changed value of my "label" is not being written to the file
when AcceptChanges() is called. Instead, the original value from within...

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...

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.

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. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
