Hi,
I've tried searching for this issue but I cannot form my question into words lol

Basically, I have a datagridview.
the first column will be a name, for example test1.
the second column will be a status, in this case running, or not running.
I am going to execute a program from my program, it will add a name to the datagridview and while it is running the status will say running. when the program closes I want the status column to change to not running.
I also need multiple of these, for example 5 programs running at once.

Any help will be appreciated :)

Run your target process, check the process if running. That's all.

It's in C#, but you should be able to make sense of it. I'm sure there's a few unhandled edge cases, but I'll leave those for you to figure out. There's plenty of room for expansion as well.
Good luck on your project. 🤝

Launch code:

Code

private void LaunchProcess(string displayName, string path, params string[] args)
{
   // create new process and allowed event raising
   var process = new Process()
   {
       EnableRaisingEvents = true
   };

   // set file path
   process.StartInfo.FileName = path;

   // create process data object to store display name and process refernce
   var processData = new ProcessData(displayName, process);

   // attempt to start the process
   var started = process.Start();

   // add process to DataGridView with the proper started status
   dataGridView1.Rows.Add(processData, started ? "Running" : "Stopped");

   // when the process is closed, find its ProcessData object in the DataGridView and update its status
   process.Exited += (s, e) =>
   {
       foreach (DataGridViewRow row in dataGridView1.Rows)
       {
           if (row.Cells[0].Value == processData)
           {
               row.Cells[1].Value = "Stopped";
               break;
           }
       }
   };
}

Simple wrapper class to store display name and process:

Code

public class ProcessData
{
   public string DisplayName { get; }
       
   public Process Process { get; }
       
   public ProcessData(string displayName, Process process)
   {
       DisplayName = displayName;
       Process = process;
   }
       
   public override string ToString()
   {
       return DisplayName;
   }
}

Usage:

Code

LaunchProcess("Notepad", "notepad.exe");
