Cuando SynchronizingObject es null , se llama a los métodos que controlan el Exited evento en un subproceso del grupo de subprocesos del sistema.When SynchronizingObject is null, methods that handle the Exited event are called on a thread from the system thread pool. Para obtener más información acerca de los grupos de subprocesos del sistema, vea ThreadPool .For more information about system thread pools, see ThreadPool.

Cuando el Exited evento se controla mediante un componente de visual Windows Forms, como Button , el acceso al componente a través del grupo de subprocesos del sistema podría no funcionar o podría producir una excepción.When the Exited event is handled by a visual Windows Forms component, such as a Button, accessing the component through the system thread pool might not work, or might result in an exception. Para evitar esto SynchronizingObject , establezca en un componente de Windows Forms, lo que hace que los métodos que controlan el Exited evento se llamen en el mismo subproceso en el que se creó el componente.Avoid this by setting SynchronizingObject to a Windows Forms component, which causes the methods handling the Exited event to be called on the same thread on which the component was created.

Si Process se utiliza en Visual Studio 2005 en un diseñador de Windows Forms, SynchronizingObject se establece automáticamente en el control que contiene Process .If the Process is used inside Visual Studio 2005 in a Windows Forms designer, SynchronizingObject is automatically set to the control that contains the Process. Por ejemplo, si coloca un Process en un diseñador para Form1 (que hereda de), Form la SynchronizingObject propiedad de Process se establece en la instancia de Form1 :For example, if you place a Process on a designer for Form1 (which inherits from Form) the SynchronizingObject property of Process is set to the instance of 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

Normalmente, esta propiedad se establece cuando el componente se coloca dentro de un control o formulario, porque esos componentes están enlazados a un subproceso concreto.Typically, this property is set when the component is placed inside a control or form, because those components are bound to a specific thread.
