Public Property SynchronizingObject As ISynchronizeInvoke

Valor de propiedad

ISynchronizeInvoke

ISynchronizeInvoke utilizado para calcular las referencias de las llamadas del controlador de eventos emitidas como resultado de un evento Exited del proceso.

Comentarios

Cuando SynchronizingObject es null, se llama a los métodos que controlan el Exited evento en un subproceso del grupo de subprocesos del sistema. Para obtener más información sobre los grupos de subprocesos del sistema, vea ThreadPool.

Cuando un componente de Windows Forms visual controla el Exited evento, como Button, el acceso al componente a través del grupo de subprocesos del sistema podría no funcionar o podría producir una excepción. Evite esto estableciendo SynchronizingObject en un componente de Windows Forms, lo que hace que se llame a los métodos que controlan el Exited evento en el mismo subproceso en el que se creó el componente.

Process Si se usa en Visual Studio 2005 en un diseñador de Windows Forms, SynchronizingObject se establece automáticamente en el control que contiene .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:

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, ya que esos componentes están enlazados a un subproceso específico.
