Hi,
I'm writng a control derived from UserControl (let's call this control
MyControl) that itself is meant to be derived further times.
MyControl hosts a public collection of specialized non-GUI objects.
This collection is therefore accesible from any controls derived from
MyControl. Derived controls have to be able to add, change and remove
objects from the collection.

Using ideas provided by some of you I was able to figure out how to get the
names of the parameters fields of a crystal report specified at run time.
The code below just basically puts the data into a comboBox. One thing I
noticed, however, is that this method shows me both the parameters used by
the main report and parameters used by the sub-report(s).

Hi,
I am trying to create a User Control that is located in a seperate class
library. The User Control contains a textbox and a button.
The page generates an exception when it tries to access the code variable
that are supposed to be linked to the contained controls.
It runs fines when everything is contained in a single web form project.
What do I need to do to make it work from a class library?

I have a base class derived from System.Web.UI.Page, and derived classes
derived from the base class. The base class has protected HTML hidden
fields in it, and the derived class's aspx page has these hidden fields
specified. So far everything is OK.
However if I open the derived class's aspx page in the Web Form
designer, it immediately puts an asterisk on the tab, meaning some
change needs saving without my having done anything. If I...

Hello all,
I am quite new to c++/. Net so please don't shoot me down for being a newbie. Any way I am trying to make a simple multithreading program that is just to learn the ideas behind it (before I incorporate them in another program). I just can’t seem to get a non-static call to work in my thread that has access to the Form1 variables and controls I need. I can call a non-static function using another class but then I can seem to get in...

public partial class SmartForm : Form
It contains methods for things like remembering position, fading in or out, logging and so on. If I open the original SmartForm Visual Studio knows to open it in the right Forms Designer and I can add controls at design time.

Hello,
I currently fight with a problem during the derivative of WinForm controls.
In Visual Studio I created a new User Control. This control is derived from
the DataGridView of the System.Windows.Forms namespace. I want to use this
control as a template for futher controls. Within this control i want to set
some property values to be pre-defined for further derived controls.
My base class looks like this:

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. 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....
Now, this would greatly impact the work of software developers. The idea...
