using pipes for communication

[el7akika]

hi

i want to communicate between simulator1 and simulator2

I use pipes, but, um, it doesn't seem to work right.

The main idea is to have a process(main) simulator1 that creates
another(child)simulator2 using CreateProcess().

i launch simulator 2 and establish a communication with him

when it finishes simulation it me sending a message (I finished) thus
I will send another message to him says make another simulation

reamrque: I do not want to use the communcation with the dos window

Are you sure your question is related to the VB.NET programming language?

If you want to setup communication between two applications, you can use
sockets or remoting, for example, which are supported by the .NET Framework
directly.

Are you sure you created both ends of the pipe(s) as described
in the example in the reference? You can also look at my earlier post

So you would WriteFile() and then ReadFile()...

Well.. if you really have a DOS window then you must communicate with
DOS. Or did you mean Console window?

In Win32 Sockets, Mailslots, NamedPipes, Shared Memory(Memory mapped
files) could be used for the IPC between two processes.

Another programmer and I each wrote a program that forms a cooperative
system. The two programs communicate in both directions IIRC via a named
pipe and the system works just fine. But it's limited to Win2K and later
systems.

thank you very very much for your answer , I want an example
have you a code in c++ for a communication between two process ?
thanks

Why not NT4 ? Anyway, only Win2k and later are nowadays supported....
