Have status in a datagridview - Takehito Morokuzu - Jun 7, 2019
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");
