Signaling between processes

I am converting some legacy code which will consist of 2
WinForm applications. In the legacy code Process A
signaled Process B using a named event (e.g. each process
attempts to Open the same named event, the first to fail
will do a Create on the named event from that point on
Process B will signal Process A by setting the named
event and Process B has a thread blocked on waiting for
the event which when fired will be immediately reset as
the thread executes the process being signaled). In
the .NET world (C#) what would be the most efficient way
to signal between two separate processes? It appears to
me that a mutex could be used (although I'm not clear on
how I'd implement the WaitFor and Release in each process
to indicate a signal from Process B to Process A); I
could send a window's message to Process A but this seems
like overkill since no data needs to be passed (the old
WM_COPYDATA); Is there a better solution to signaling
between processes that will always run on the same
machine (no need for Net Remoting)?
Thanks in advance for any help that may be offered on
solving this issue...

My application starts up a number of processes for various purposes using: self.popen = popen2.Popen3("/usr/local/bin/python -O "myscript.py") and then shuts them down when appropriate with os.kill(self.popen.pid, signal.SIGTERM) Everything works fine on MacOSX.

I need to use some kind of signaling among processes, but the only thing I found that can something like that is the Mutex. But the Mutex doesn’t have a real signaling, it only has Wait() and Release(), the trouble is that the Wait returns not only if the Mutex is released, but also if I’m the only one who created it or the only one that has it, and that is not good for me. I need to know if the other process signaled or not,...

Hello All, In IIS 6.0 We have a concept of worker processes and application pools. As I understand it, we can have multiple worker process per appliction pool. Each worker process is dedicated to a pool. If I assign only one application to a applicaton pool and have multiple worker processes assigned to that pool. Will my application be processed by many worker processes?

Alright, based a on discussion on this mailing list, I've started to wonder, why use threads vs processes. So, If I have a system that has a large area of shared memory, which would be better? I've been leaning towards threads, I'm going to say why. Processes seem fairly expensive from my research so far. Each fork copies the entire contents of memory into the new process. There's also a more expensive context switch between...

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.... Now, this would greatly impact the work of software developers.
