QUESTION: HOW TO PASS PARAMETERS BETWEEN TWO PROGRAMS??

Question

Hello!

I'm new in c# programming and I need you to help me with this problem:

I've created two programs in C#. The first one called "FM" and is only a program with a lot of functions. The second one called "MCDU" and is the main program.
The problem is that I need to pass some parameters of "MCDU" to "FM" in order that the second program executes with this parameters one of the functions that has in its code. So, how I pass from "MCDU" the parameters to "FM" and also how I return new parameters from "FM" to MCDU?

Thanks in advance and if you need a better explanation please ask for it!

hi then in this case u are running a program from the other and pass parameters for it but in case that the 2 programms run independently so u cannot pass parameters this way and thanks too much for the example

This is an example caught from csharpfriends. In this example the App2 should know if from App1 a checkbox has been checked or not. Here you have the code I hope it helps you as well as it helped me. Call the App2 form App1 with System.Diagnostics.Process.Start(App2.exe0); if the checkbox is not checked and System.Diagnostics.Process.Start(App2.exe1); if the checkbox is checked. From the App2 you can get the argument (01) from using System.Text; using System.Text.RegularExpressions; Regex Splits=new Regex(@ ); string param=Splits.Split(Environment.CommandLine); if(param.Length>1) { param[1]; // is 0 or 1 }

hi can u give an example of how to use processes to do that as it may be an easier solution if u are right do u mean that one form is calling the other (run it) using something like Process.Start() and pass some arguments to the other program ? thanks

hi i am a beginner too but i think that if the 2 programs run in separation (independent no form call the other form )u need to use remoting or network programming or com+ remoting enables u for example to create an object in a program and to use it in another program remoting in fact is based on network programming but with specific message formatting between the 2 programmsand wish support of classes to help in the process of transfering objects if u use network programming u will define of course the message format u need i suggest that u read about remoting. best wishes
