获得另一个应用程序窗口中的文本,如果您在用C编程，自然用HWND代替CWnd。有人肯定会问：嘿，等一下——如果这样做可以的话，为什么GetWindowText不起作用呢？WM_GETTEXT不就是GetWindowText发送的吗？错也，GetWindowText只在窗口属于当前进程时才发送WM_GETTEXT，否则它干别的事情。这一点文档中说得很清楚：
-Access to another application window, the text, if you use the C programming, natural to use HWND instead of CWnd. Some people will surely ask: Hey, wait a minute- if you can, if you do, why GetWindowText does not work it? GetWindowText sent WM_GETTEXT not that it? Wrong also, GetWindowText only when the window is the current process to send WM_GETTEXT, otherwise it do other things. This is clearly stated in the document:
