I've tried to create 11 textboxes as variables (not actually visible in
the program, not in Windows Form Designer) and have set DataBindings to
the text properties of the TextBoxes BUT according to tests I've run, it
says that the DataBindings exist, but the IsBinding is set to False, and
is ReadOnly (the bindings exist, they just aren't active AND I
can't/don't know how to make them active). Is there any way to allow
these 11 textboxes'...

Well, I'm still wondering around in the "land of the lost exception"...
It seems that controls that are bound to a class and the class throws an
error in the SET method of the bound member, the exception cannot be
caught. I have wrapped my entire application in all the global
exception handlers I can find, and still to no avail. In fact all the
Try/Catches and Exception event handlers are worthless...
Put on your advanced thinking...

Hi,
I'm dealing with a master-detail relationship. A datagrid bound to the
detail data. When navigating through the records (next record:
Me.BindingContext(mDv1).Position += 1), I notice a delay of about 2 sec's if
the detail datagrid is empty (no records to show for this master-record). The
delay happens only once per application run!! After exception debugging a
found that when this happens a "first chance exception of type...

Ok this should be simple.
I made a form, added a combobox (for selecting items to edit, not for updating fields), several textboxes, a few checkboxes etc. On formshow it connects to my database, draws down the existing data, no problem. All the records in the datatable that were the result of a query, I could select from, and the other databound components would display the records contents, no problem..... however.... when i add a new row, the...

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....
