Hello:
I am encountering a very weird issue with MDI child, Overriden WndProc
function and hidden form.
Basically, the application has two forms, Form1(parent form),
Form2(Child form), Form2's WndProc method is overriden, if the message
is CLOSE message, just hide the form. I first initialize and show the
child form, then close it by clicking the Close(X) button, the
overriden WndProc method gets invoked, and the form is hidden. Then

Further to my last post, I have managed to get a child window to display. But its messages are routed to the same WNDPROC that the main window's messages are routed to - what is the way of identifying from the lParam or wParam whether the message came from a child window or the parent? And what if the message uses some other data in the wParam or lParam? Is it better to use one wndproc for the parent window, and one wndproc for all child windows...

For some reason, when I click the X to close my MDI parent form, the action
appears to be re-directed to one of the MDI child forms, and the parent
remains open. I am then unable to close the application.
What should happen, is that the main MDI form should close, taking the child
forms with it. There is code to loop through the child forms, remove the
controls on each of them, and then close the form, but this code should
execute only...

before killing them off.

I'm trying to write a Python app which accepts a socket connection and
then spawns another Python process to handle it. I need it to run
under both Linux and Windows. I have it working under Linux, but am
having problems with the Windows implementation.
My app uses the subprocess.Popen class to spawn the child process. The
first problem I ran into was that Windows Python won't let you pass a
socket object via the Popen stdin argument...

I am trying to spawn a process (say an exe file) with different user
crendentials than that of the current user.
1) Called LogonUserEx() to logon the user and recieve a handle to the
token that represents the logged-on user.
2) Called ImpersonateLoggedOnUSer() to let the calling thread
impersonate the security context of logged on user.
3) Used CreateEnvironmentBlock() to get lpEnv

Hi,
As part of my efforts to write a test tool that copes with GUIs
nicely, I'm trying to establish how I can start a GUI process on
Windows that will not bring up the window. So I try to hide the window
as follows:
info = subprocess.STARTUPINFO()
info.dwFlags |= subprocess.STARTF_USESHOWWINDOW
info.wShowWindow = subprocess.SW_HIDE

I have a Python script which is used to load data into a database. Up to
now this script has been run by customers from the Windows command

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...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
