应用程序本身绘制该矩形。
也许您可以更好地描述您的问题？我想我明白了，你想要捕捉矩形的范围，但我不太确定你的实现，环境等。
The application itself draws that rectangle.
Perhaps you could describe your problem a bit better? I think I understand it, that you want to capture the range of the rectangle, but I am not quite sure of your implementation, environment, etc.

你好：
我不想绘制，我想要捕捉矩形测量，我说的矩形是当你按下鼠标左键并在桌面上拖动鼠标（Windows资源管理器）时的矩形。 />
如果无法解决这个问题，请给我矩形位置（x，y）。
谢谢.....
Hello:
I dont want draw that, I want to capture the rectangle survey, the rectangle I talk about is the rectangle when you press left-Mouse button and drag the mouse in the desktop (windows explorer).
IF cant solve this, give me the rectangle position(x, y).
Thanks.....

当我这样做时，我抓住了mousedown和mouseup事件。他们的鼠标事件args具有当时鼠标的位置。
但这只有在您的程序成为焦点时才有效。如果没有，你将需要一个解决方法，其中我知道如何这样做的唯一方法是使用DirectX。
如果你想要解决方法，告诉我，我会为它发布一些代码。
When I did it, I just grabbed the mousedown and mouseup events. Their mouse event args have the location of the mouse at the time.
But that would only work if YOUR program held the focus. If it does not, you will need a workaround, in which the only way I know how to do so would be with DirectX.
If you want that workaround, tell me and I will post some code for it.
