Breakpoints et les threads.
Bonjour.
Pourriez vous m'expliquer pourquoi en debug, si je met un breakpoint dans un thread, lorsque celui ci est atteind, ca met tous les threads en cours, et non uniquement le thread concerné?
Il y a t'il un moyen d'éviter cela?
Ci dessous un ptit code d'exemple, mettez un breakpoint dans la methode ThreadA ou ThreadB, lancez les 2 threads:
