What's the best way to check that
-
Hi all, I want to execute and exe, basically a process. Everything is fine. But I want to know what's the best way to handle this. Let me explain. Say I start the process on a click event, but the button is not disable. So a user can click on it again. At that point I want to check that process is already running. If it's running I don't want to run it again. What I have done here is, use a global variable and once the process is started make it to true. Once a user click that button, simply validate that variable. Is that a good practice? Thanks

I would disable the button on starting the process and enable it back when the process is done working. Like this:
private void button1_Click_1(object sender, EventArgs e) {
button1.Enabled = false;
Process proc = new Process();
proc.StartInfo.FileName = "notepad.exe";
proc.EnableRaisingEvents = true;
proc.Exited += new EventHandler(proc_Exited);proc.Start();
}void proc_Exited(object sender, EventArgs e) {
button1.Enabled = true;
}Regards, Lev

You can use Process.GetProcessesByName[^] method to find out if the process is already running.

I have a class that I call Runner. It starts the required process, and then starts a background worker object that serves to allow the programmer to terminate the process. When the process terminates (either normally or by user-intervention, it fires a custom event and the calling form handles the event. Using a class like this, you could disable the button when the process is started, and re-enable it when the process terminates. Alternatively, you could leave the button enabled and check to see if a globally-defined runner object is != null to see if you should display a message to the user or not. I originally wrote this code so that I could track how much time was spent running the spawned process.

But the reason is I cannot disable the button. On that single click event I want to start two process. One of it is continuously running, that's what I want to check in this case. Other process can be start/stop randomly.

But the thing here is I cannot disable the button. As I said in earlier post, in that click event I have to start two process.

Well, if you cannot disable the button, then, I guess, you should go for what Giorgi has suggested

Would you like me to post the code for you?

Well, the behavior of this button is rather confused for user. Sometimes, refactor the design would be better choice. :rolleyes:

Hello, Here is the code private void button3_Click(object sender, EventArgs e) { button3.Enabled = false; Process proc = new Process(); proc.StartInfo.FileName = "notepad.exe"; proc.EnableRaisingEvents = true; proc.Exited += new EventHandler(proc_Exited); proc.Start(); } void proc_Exited(object sender, EventArgs e) { myDelgate d = new myDelgate(enableBtn); this.Invoke(d); } void enableBtn() { button3.Enabled = true; } Remember u should add the statement public delegate void myDelgate(); inside the class which declare a delegate I hav sucessfully disable the button on starting notepad and enable afte exiting the notepad hope this code will help you.
