SUMMARY

This article describes how to check if a particular program is running.

DISCUSSION

As an example, let us assume that you want to run your program, only if there is not another autorun.exe running on the system. To accomplish this use the Window.EnumerateProcesses action, and check every process against the filename autorun.exe.

Insert the following code into the On Show event of your page:

instances_of_file = 0;


--have all lowercase


file_to_check_for = "autorun.exe";


processes = Window.EnumerateProcesses();





for j, file_path in processes do


      file = String.SplitPath(file_path);


      if (String.Lower(file.Filename..file.Extension)) == file_to_check_for then


          instances_of_file = instances_of_file + 1;


      end


end





if instances_of_file > 1 then


      Window.Hide(Application.GetWndHandle());


      Dialog.Message("Error", "Autorun already running: code: already running");


      Window.Close(Application.GetWndHandle(), CLOSEWND_TERMINATE);


else


      Window.Show(Application.GetWndHandle());


end
