Here's what I want do:
Have a main daemon which starts up several threads in a Boss-Queue structure.
From those threads, I want them all to sit and watch a queue. Once an entry
goes into the queue, grab it and run a system command.
Now I want to make sure that system command doesn't hang forever, so I need some
way to kill the command and have the worker thread go back to work waiting for
another queue entry.

In simplified form, I have an RTF control and a timer. I use the timer to do
an autoresave for the RFT control every 5 minutes. Here is the abridged code.

Hi all,
I'm having a weird time with a call to the Refresh() method of a
DataGridView. I have a VB.NET 2005 Windows application with a main form and
a "worker" thread. The main form delegates a Sub to the worker so that the
latter can refresh the DataGrid after updating the DataTable driving it.
When I run the app under the debugger, everything's fine. But when I run it
for real, it hangs, apparently in the Refresh() method of the...

Hi,
I'm interested in developing an application that needs to run on more
than one operating system. Naturally, a lot of the code will be shared
between the various OSs, with OS specific functionality being kept
separate.
I've been going over the various approaches I could follow in order to
implement the OS-specific functionality. The requirements I have are
as follows :

Hi peoples....
This is a pain in the ass:
Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on.
I am trying to update the text in the textbox when data is recieved on the new SerialPort control.
So I added the following:

Dear reader,
By opening an application I get always the main Access window with the
closing cross in the above right corner. Is there a possibility to make
this closing cross invisible?
All the settings in the Start-up form under Tools are disabled but the
closing cross in the above right corner is still visible.

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,...
