Multiple instances of executables?

I want to schedule task in "Schedule tasks" that starts an app (build in
vb.net 2005) every 5 minutes. Every time the app starts i want to check if
this job with the same task name, task name is passed as an argument to the
app at start, is completed. If its not completed, just quit.

Schedule tasks:
==========
myApp.exe "TaskNameOne"
myApp.exe "TaskNameTwo"
myApp.exe "TaskNameThree"

How can i check if the "taskname" is already running?

Diagnostics.Process.GetCurrentProcess.StartInfo is empty.

Thanks in advance!

Hello,

Diagnostics.Process.GetCurrentProcess.StartInfo only have value when we set
it:

ProcessStartInfo startInfo = new ProcessStartInfo("IExplore.exe");
startInfo.WindowStyle = ProcessWindowStyle.Minimized;
Process.Start(startInfo);

startInfo.Arguments = "www.northwindtraders.com";
Process.Start(startInfo);

To get the arguments from command line, we nee to change the main()
function in in program.cs:

[STAThread]
        static void Main()
        {
           ...
        }

to

[STAThread]
        static void Main(string [] args)
        {
          ...
        }

After get the arguments here, I suggest you may record them in a Text file
on local disk, and delete the record when the applicaiton is quiting. when
a new instance is running, it can first check the text file to see if the
same argument has been recorded.
