Detecting a program if it is running.


Is it possible to detect if a program is running in the system ? For example "ZoneAlarm".

I found a discussion about it, but it is in Visual Basic :

Just wondering if you could help with this using Delphi.

Thanks in advance,

function IsFileInUse(path: String): Boolean;
  f: file;
  r: integer;
  r := - 1;
  system.AssignFile(f, path);
  r := ioresult;  {sm(ns(r));}
  {5 = access denied}
  if (r = 32) or (r = 5) then
    result := true
    result := false;
  if r = 0 then

procedure TForm1.Button1Click(Sender: TObject);
 if IsFileInUse('C:\file.exe') then ShowMessage('Program is in use');
you could enumerate through the running processes with TLHelp32 APIs and check if a certain process name is running.
