Bonjour,
J'ai mixé le code d'un lancement externe d'application via VB auquel j'ia ajouté une redirection de la sortie standar du lancement externe vers VB.
Il marche quand il s'agit du lancement d'un .bat mais il plante quant le .bat lance un SHELL via cygwin. En revanche, un lancement sans redirection de la sortie standar du shell vers VB fonctionne.
Est-ce possible de rediriger la sortie standard d'un shell vers VB ?
Ci-dessous mon code:

Sleep(500) après ret = LaunchCmd("c:\RUN_SHELL.bat") qui crée le lancement de l'applicatin externe prend un certain temps d'autant plus long que le .bat lançait le shell. Le RunCmd qui lit la sortie du pipe arrivait donc avant que la fin du lancement soit à son terme.
