Détection mode debug

Salut,
Y a t'il un moyen de détecter dans le code si l'appli est lancée par l'IDE Delphi ou en standalone ?
Merci :D

Eventuelement cette unite me branche aussi .... est il possible de l'avoir sous forme de lien plutot (ou en meme temps) c'est pas toujours top le copier coller ...

Merci.

Quel est le problème avec le copier/coller ?

Merci beaucoup c'est presque parfait !!
Je dis "presque" car cette partie du code (tout à la fin) :

if result then 
    begin 
      reg:= TRegistry.Create; 
      reg.Access:= KEY_READ; 
      reg.RootKey:= HKEY_LOCAL_MACHINE; 
      if reg.OpenKey('Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders', false) then 
      begin 
        if reg.ValueExists('Common licenses') then 
          result:= Reg.ReadString('Common Licenses') = 'Z:\PROSIM' 
        else 
          result:= false; 
        reg.CloseKey; 
      end 
      else 
       result:= false; 
      reg.Free; 
    end;

...renvoie "false" à tous les coups (et pour cause), d'ailleurs je ne sais pas à quoi sert cette entrée registre 8O
Donc en virant ça ça marche impec' !
Merci :D

Hum... On dirait que j'avais un peu bricolé le code original. Tu as raison, cela ne sert à rien. Je l'ai enlevé du code.
