Im writing a program that does monte carlo simulation and im having
trouble figuring out how to get the threading model right. I have a
simulation class which contains all simulation data and methods to run
the simulation for an x number of sweeps. An instance of this object is
declared in the class of my main form. The main form handles graphics
(it shows the particles moving on the form). I am now trying to split
up the work so that the...

I have just upgraded from VB 4.0 to VB .NET 2002. One program under VB 4.0
was able to shut down or restart the (windows XP) machine using a series of
API calls. (Getlasterror, GetCurrentProcess, OpenProcessToken,
LookupPrivilegeValue, AdjustTokenPrivilegese, ExitWindowsEx.
I am trying to avoid using any API calls if possible and to use managed code
instead. I couldn't find any easy way of doing this but searching the
Internet with...

I am starting a program from a module with the Sub main procedure and
I want it to display two forms for the program's interface, but when I
run the program both forms just open and then program closes.
Dim FORM1 As New Form1
Dim FORM2 As New form2
Sub main()
FORM1.Show()

My unstanding of all VB up to and including vb6 is that an event could
not "interrupt" itself.
For instance if you had a timer event containing a msgbox then you would
only get one message.
However in vb.net you get continual messages (even setting the system
modal property).
Firstly, are these two assumptions right and if so what is the approved

I have written a program that functions similarly to a stopwatch.
When the user clicks the button, a label on the form starts counting. The
program, however, does not tick once a second. How can I fix this?
The following is the program. It assumes that the forms has a Button named
Button1, a Label named Label1 and a Timer named Timer1.
Dim sec, min As Double
Private Sub InitializeTimer()

Hello,
When calling the Invoke() method of a web service proxy class, this normally
is a synchroneous call, that stays untill the results are received. Gui
events are not handled in the mean time.
However, when having attached the debugger to the process (or performing F5
in VS), the process doesn't stay in the Invoke method, but handles Gui
events that were set just before. This leads of course to unwanted
behaviour, because the...

Using VS2005, I dynamically create an event delegate. Code follows question.
My method gets the event's parameters and passes them onto a common event handler. My delegate gets called when expected and in turn, calls my common event handler. However, once in the common event handler code, the "this pointer" is wrong and hence I can't access other class properties and methods.
Even if I invoke the dynamic method directly, the "this pointer" is...

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,...
