communication between 2 diff applications

[Pohihihi]

Hello NG,

My scenario is --
-----------------------------------
Application A (AppA)
Application B (AppB)

AppA & B are accessing same DB. AppA might start first or AppB might get
started first, depending on user's will. Few bin files are shared between
them. Basically AppA & B are part of a big suite of application.

My use is --
----------------------------------
AppA starts and changes information according to the actions performed on
AppBs. Also AppB might do the same.

My problem is --
----------------------------------
How to make AppA & B communicate events (real time) and information between
each other?

What I am not looking is--
----------------------------------
A solution that deals with sockets etc. Both A & B are running on same
machine so socket solution do not feel like a great solution (but I have
thought about it). Also sharing files is not a good idea. I am totally not
looking for any COM/DCOM related solutions as well. I am not familier with
remoting but could be a solution (maybe !!).


Thanks,
Po

Hi Po
You have rejected most of the options, but there are still other
options available which will help you to send and receive notification
between two different application...

One of such method is using APIs...
Use SendMessage Api to send message to the another window... and
Receive the send message in the wndproc of the another application...

Hope this will help you out...

Hi,

What you are looking for is Interprocess Communication...
Take a look at this: http://www.habjansoftware.com/ipc_library.aspx

This is IPC Library for .NET, it supports Named Pipes, Shared Memory and
Shared Events.

any examples?

 

[Pohihihi]

thanks but I will rather like to learn the process and implement it. More
over seems like networking is used in the end of your product. That was one
of the thing I list I don't want to do.

no problem.

....btw. i did not use any networking, i used only API's (CreateNamedPipe,
CreateFile, CreateFileMapping , CreateEvent, CreateMutex, CreateSemaphore
and so on....)...

Hi,

An annoying issue in .NET 1.1 is the lack of broad possibilities to do
IPC. MS seemed to take note and solved it in .NET 2.

An interesting solution is using the message WM_COPYDATA, more info at:
