使用keybd_event

Question

I have a simple program that does some 'typing' with keybd_event() . The problem is that when I focus the program window, any text box where I want to type (eg in a browser) becomes unfocused. How do I remedy that?

Answer 1

Pass the hwnd of the textbox you want to type in instead of the window who owns it, this should solve your problems. You might need to enumerate the child windows though, to get the correct resource ids of the textboxes. You should how be using SendInput , as you might find you method just not working in certain situations, see all the comments.

Answer 2

如果要防止正在生成键盘事件的应用程序获得焦点，一种选择是使用WS_EX_NOACTIVATE扩展样式创建应用程序窗口 。
