How to stop one process complete dont' start other exe

I am not sure I understand what you are asking but I assume I do. I think you are asking how to limit your application to a single instance. You can search the internet for articles about doing that. When you do you will find that the following is a solution that many experienced Windows programmers use.

Your project has a Program.cs file that has a "Main" method. Open (look at) that file. In it there is a line like:

Application.Run(new Form1());

Add the following lines in the Main method before that line:



Then after the "Application.Run(new Form1())" add the following:

GC.KeepAlive(InstanceMutex);

Also be sure to add a "using System.Threading;" at the beginning of the Program.cs file.

Hi

you can use something like that

Process[] notepads =       System.Diagnostics.Process.GetProcessesByName("notepad");
            int notepadCount = notepads.Length;

Use your exe name if you get count greater than 0 means the process is running


Thanks

In above url , they have suggested ways to acheive it.

if (Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName).Length > 1)
{
  AppLog.Write("Application XXXX already running. Only one instance of this application is allowed", AppLog.LogMessageType.Warn);
  return;
}
