Method for the control . then these client coordinates are sent along with the tvm hittest message to determine if and where the 然后，这些客户端坐标随同tvm _ hittest消息一起发送，以确定是否单击了
All coordinates for child windows are client coordinates ( relative to the upper - left corner of the parent window ' s client area ) 这句话的意思应该是：所有的子窗口的坐标都是指客户区坐标（相对于父窗口客户区域左上角而言的） 。
Client coordinates ensure that an application can use consistent coordinate values while drawing in a form or control , regardless of the position of the form or control on the screen 工作区坐标确保了无论窗体或控件在屏幕上的位置如何，应用程序在窗体或控件中绘制期间都可以使用一致的坐标值。
Provides information about the current state of the mouse , including the location of the mouse pointer in client coordinates , which mouse buttons are pressed , and whether the mouse wheel has scrolled 提供有关鼠标当前状态的信息，包括鼠标指针在工作区坐标中的位置、按下了哪个鼠标按钮以及是否滚动了鼠标轮。
Because some mouse location information is in client coordinates and some is in screen coordinates , you may need to convert a point from one coordinate system to the other . you can do this easily by using the 由于某些鼠标位置信息使用的是工作区坐标，而某些使用的是屏幕坐标，因此，您可能需要将某个点从一种坐标系转换为另一种坐标系。
In the way of realization , considering the practical need and the progress of webgis technology , webgis is first implemented in electric power communication supervision system . the activex component in client coordinates the webgis component 论文在监控系统的实现形式上，结合工程的实际需要与webgis技术的发展，首次在电力系统完成与webgis相结合的电力通信网监控系统。
