取另一程序的键盘输入焦点，关键是两个程序共享输入。

本程序中，输入了窗口标题后，点击GetFocus按钮，（稍候）程序将找到该窗口，并取出该窗口的输入焦点，并显示。如果没有输入焦点，显示为0x0.

也能设置输入焦点，不过只是为了让程序大一些免得通不过审核，你可以自行看一下，应当不难。-Another program to take keyboard input focus, the key is two programs to share input. This program, enter the title of the window, click the button GetFocus, (wait) program will find the window, and remove the window the input focus, and displayed. If there is no input focus, shown as 0x0. Can also set the input focus, but only in order to avoid the program to pass larger review, you can look at themselves, it should be easy.
