group:Communicate UNIX from c#
dotnet windows forms:
Hi,
How do i communicate between C# and Unix? The scenario is as follows. I have a C program residing in UNIX box that does complex calculations and returns a result. I need to invoke this C program residing in the Unix box from Windows Client C# application through a button click event. How do i manage to call a C program residing in Unix box from C# and get the result back? It would be really helpful if you expalin me a way to acheive this. Thanks -Bala
This sounds like an ideal Web-Service scenario.
I have seen situations where WinForms clients used a java webservice on a Linux box for processing tasks.

I gave you an elaborate reply when you first posted this very same question in the Remoting newsgroup. Have you seen that? Oliver Sturm -- Expert programming and consulting services available
Thanks everyone for your response. Actually i will not be able to implement
a web service in the UNIX box due to some constraints. Leaving the Web service do i have any other option?

That's a 2 step problem.
1st your unix program work in 'server mode', that is be able to listen to incoming connection and answer them somehow. 2nd your client should talk to this server. Now if you maintain both product and that the C program has no server mode, you should develop one. As Bob suggested develop it as a WebServicde server sounds like an appropriate idea. -- If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins.

Sockets? Write a simple server for the unix box and hit it with a socket

Thanks a lot. Sockets just work fine.
Another question. My server program in the Unix box accepts only a C struct type. How do i pass a struct from C# client application that is compatible with the server C program?How do i modify my client c# application without changing anything in the server?

I advise you to check which format expect the C server and write the same thing in C#. BTW web services are just for that. every time you want to call a new method or pass a new parameter, you've got plenty of tedious coding to write. Web service are real easy to write in C#. In C it would still be a tedious task but, at least, you will find plenty of library which makes it 'relatively easy' as far as C program are concerned...
Hi Bala,
To use C# on Unix, we must have .Net Framework installed. Currently, the Unix version of .Net is Mono, we may install mono to run C#. With Mono, I think we can use Process.Start to run an executable.

Hi Bala,
FTP is a standard protocol, which is independent of the OS platform. So we can first install a FTP server ware on the Unix machine, then on client machine, we can use C# socket classes to write a FTP client to communicate with the server ware. There are a lot of articles about how to write a FTP client in .Net, please refer to: "FTP Explorer in C# (Beta 2)" http://www.c-sharpcorner.com/winforms/NFTPExplorer_Beta2.asp "Write an FTP Client with VB.NET to Bridge Legacy Software" http://www.codeguru.com/vb/vb_internet/html/article.php/c8459/ Hope this helps Best regards, Jeffrey Tan Microsoft Online Partner Support Get Secure! - www.microsoft.com/security This posting is provided "as is" with no warranties and confers no rights.
Thanks for the reply. I will not be able to write a Web Service on the
server due to some constraints though it is an excellent idea. Another question: Is there a way to FTP a file to a Unix box and get a file back from C# application?

How do i logon to a Unix box and invoke an executable in that box through
c#? Thanks -Bala [quoted text, click to view] "Lloyd Dupont" <ld@NewsAccount.galador.net> wrote in message news:ely5fqayFHA.788@tk2msftngp13.phx.gbl... >> Another question.

Thanks a lot for the response. I have not tried it yet but your idea has pointed me in the right direction. Thanks for the support.
