Blocks the calling thread until a thread terminates or the specified time elapses , while continuing to perform standard com and sendmessage pumping 在继续执行标准的com和sendmessage消息泵处理期间，阻塞调用线程，直到某个线程终止或经过了指定时间为止。
The handle to the active window attached to the message queue of the calling thread ; otherwise , a null reference nothing in visual basic 附加到调用线程的消息队列中的活动窗口的句柄；如果没有附加到调用线程的消息队列中的活动窗口，则为空引用（在visual basic中为nothing ） 。
The asynchronous overloads will start the operation on another thread and then return immediately , allowing the calling thread to continue while the operation executes " in the background . 异步重载将在另一个线程上启动操作，然后立即返回，允许在调用线程继续执行的同时让操作“在后台”执行。
Initializes a new instance of the semaphore class , specifying the maximum number of concurrent entries , optionally reserving some entries for the calling thread , and optionally specifying the name of a system semaphore object 类的新实例，并指定最大并发入口数，还可以选择为调用线程保留某些入口，以及选择指定系统信号量对象的名称。
In visual basic , adsi binds to the object using the security context of the calling thread , which is either the security context of the user account under which the application is running or of the client user account that the calling thread is impersonating ）时， adsi将使用调用线程的安全上下文来绑定到对象，该上下文是应用程序运行的用户帐户的安全上下文或调用线程模拟的客户端用户帐户的安全上下文。
Initializes a new instance of the semaphore class , specifying the maximum number of concurrent entries , optionally reserving some entries for the calling thread , optionally specifying the name of a system semaphore object , specifying a variable that receives a value indicating whether a new system semaphore was created , and specifying security access control for the system semaphore 类的新实例，并指定最大并发入口数，还可以选择为调用线程保留某些入口，可以选择指定系统信号量对象的名称，指定一个变量来接收指示是否创建了新系统信号量的值，以及指定系统信号量的安全访问控制。

Initializes a new instance of the mutex class with a boolean value that indicates whether the calling thread should have initial ownership of the mutex , a string that is the name of the mutex , a boolean variable that , when the method returns , indicates whether the calling thread was granted initial ownership of the mutex , and the access control security to be applied to the named mutex 使用一个指示调用线程是否应拥有互斥体的初始所属权的布尔值、一个作为互斥体名称的字符串、一个在方法返回时指示调用线程是否被授予互斥体的初始所属权的布尔变量、以及要应用于已命名的互斥体的访问控制安全性来初始化
