You would do this in the exact same way that you have already been told.

you can check command line parameter !!
by default it shows 1 parameter that is exe name what you have to do is pass dummy param. from command line and check the length of params. from command line if only 1 param that means from clik and more thn two is from command line so you can skip that time !
this is tricky way that i can suggest you

<pre lang="c#"><pre> 
   static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            var par = Environment.GetCommandLineArgs();
            if (par.Length > 1)
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
            }
        }
    }

Solution 2

You cannot check the command line parameters of one .EXE from another one.

Your "parent" .EXE has to pass the parameters it needs to on the command line of the second .EXE when you launch it.

How can we write code for this?

I'd guess you have a lack of understanding arround processes and execution therefore your not "so good" question. I'll try to summarize what I understand.

You wan't to start another process/executabel from within your C# application?

Solution:
Have a look at Process.Start http://msdn.microsoft.com/de-de/library/system.diagnostics.process.start(v=vs.110).aspx[^]
In essence you give this method the file path of the executable and (if you want) command line arguments.

You want't to hinder other users from starting that application.

Possible (Hack-)Solution.
As others suggested (IF you have access to "other" exe's code) you could implement a check for a specific commandline argument (or Count)you would send from your application but user wouldn't just by "clicking".

Other Solution.
Do it with default OS Features (rights/policies)
"pack" the executable within your application (embedded resource?) so that it doesn't "appear" on the users system outside the context of your application.
...

So maybe answer the open questions (Access to "other" exe) and try to use Process.Start

Kind regards Johannes

(Don't get me wrong, but your answer to "solution1" ("my exe is not running by this method") hints to a clear lack .NET knowledge - how should a argument line check and the "normal" boilerplate code you get with a new WindowsForms-project (you have seen that code, have you?) start an exe? So all good answers won't help you if can't put it to code, nobody can circumvent learning some basics...)
