Detecting a program if it is running.

Hello,

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 :

http://groups.google.nl/groups?hl=nl&lr=&threadm=uU%24DlimvBHA.2324%40tkmsftngp02&rnum=15&prev=/groups%3Fq%3Ddetecting%2Bzonealarm%26start%3D10%26hl%3Dnl%26lr%3D%26selm%3DuU%2524DlimvBHA.2324%2540tkmsftngp02%26rnum%3D15

Just wondering if you could help with this using Delphi.

Thanks in advance,

  {$I+}
  r := ioresult;  {sm(ns(r));}
  {5 = access denied}
  if (r = 32) or (r = 5) then
    result := true
  else
    result := false;
  if r = 0 then
    system.close(f);
end;

//Usage:
procedure TForm1.Button1Click(Sender: TObject);
begin
 if IsFileInUse('C:\file.exe') then ShowMessage('Program is in use');
end;

you could enumerate through the running processes with TLHelp32 APIs and check if a certain process name is running.
