Remarques

Quand SynchronizingObject est null, les méthodes qui gèrent l’événement Exited sont appelées sur un thread du pool de threads système. Pour plus d’informations sur les pools de threads système, consultez ThreadPool.

Lorsque l’événement Exited est géré par un composant visuel Windows Forms, tel qu’un Buttoncomposant , l’accès au composant via le pool de threads système peut ne pas fonctionner ou entraîner une exception. Évitez cela en définissant SynchronizingObject sur un composant Windows Forms, ce qui entraîne l’appel des méthodes qui gèrent l’événement Exited sur le thread sur lequel le composant a été créé.

Si est Process utilisé dans Visual Studio 2005 dans un concepteur de Windows Forms, SynchronizingObject est automatiquement défini sur le contrôle qui contient le Process. Par exemple, si vous placez un Process sur un concepteur pour Form1 (qui hérite de Form) la SynchronizingObject propriété de Process est définie sur le instance de Form1:

this->process1->StartInfo->Domain = "";
this->process1->StartInfo->LoadUserProfile = false;
this->process1->StartInfo->Password = nullptr;
this->process1->StartInfo->StandardErrorEncoding = nullptr;
this->process1->StartInfo->StandardOutputEncoding = nullptr;
this->process1->StartInfo->UserName = "";
this->process1->SynchronizingObject = this;

process1.StartInfo.Domain = "";
process1.StartInfo.LoadUserProfile = false;
process1.StartInfo.Password = null;
process1.StartInfo.StandardErrorEncoding = null;
process1.StartInfo.StandardOutputEncoding = null;
process1.StartInfo.UserName = "";
process1.SynchronizingObject = this;

process1.StartInfo.Domain = ""
process1.StartInfo.LoadUserProfile = False
process1.StartInfo.Password = Nothing
process1.StartInfo.StandardErrorEncoding = Nothing
process1.StartInfo.StandardOutputEncoding = Nothing
process1.StartInfo.UserName = ""
process1.SynchronizingObject = Me

En règle générale, cette propriété est définie lorsque le composant est placé à l’intérieur d’un contrôle ou d’un formulaire, car ces composants sont liés à un thread spécifique.
