Hi all.
Probably a quick one, I'm using PostMessage to send keys to an applicatoin
but how do I convert the key string to a long values so that I can pass this
to the wParam. The definition is below
Private Declare Auto Function PostMessage Lib "user32" ( _
ByVal hWnd As IntPtr, _
ByVal Msg As Integer, _
ByVal wParam As Long, _

I use PostMessage to drive an application by sending it keyboard
events. Messages that are sent with no modifiers are processed well.
As an example, the '.' key message sent here:
My messages:
Recognized: "Release brakes"
Message: 0x100 wParam: 0xbe lParam: 0x340001
Message: 0x102 wParam: 0x2e lParam: 0x340001
Message: 0x101 wParam: 0xbe lParam: 0xc0340001

Hi,
Using P/Invoke I use PostMessage to send a message from one thread to
another. I'm pretty sure this has already worked in dotnet. but I've
upgraded version 2 few day ago.
Now I have an illegal cross thread operation if posting a message. Is this a
bug introduced in latest version of dotnet ? It is very legal to use
postmessage because the message will execute in context of the thread the
one was posted to. Same with...

When using PostMessage to post myself a message, the msg and wparam
parameters somehow get swapped over. They are in the correct order when
calling PostMessage but by the time wndproc handles the message msg is now in
the wparam position and msg is set to 0 (NULL message).
Does anyone know why this behaviour is occurring ?
I've included a simple test form below to illustrate this...

Can anyone explain why PostMessage to a Windows Form
is considered unsafe and raises InvalidOperationException?
I can get rid of that setting CheckForIllegalCrossThreadCalls
to false and everything works just fine. Still I feel somewhat
uncomfortable.

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...

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,...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
