Windows XP 中的纯消息窗口未接收到 WM_POWERBROADCAST
我试图找出广播消息是否会发送到仅消息窗口，即创建为：
hWnd = CreateWindow(MAKEINTATOM(RegisterClass(&wnd)), NULL, 0, 0, 0, 0, 0, 0, HWND_MESSAGE, hInstance, 0);
问题是我没有收到任何广播消息到该窗口...;)
I'm trying to find out whether broadcast messages will be sent to message only windows, i.e. created as:
hWnd = CreateWindow(MAKEINTATOM(RegisterClass(&wnd)), NULL, 0, 0, 0, 0, 0, 0, HWND_MESSAGE, hInstance, 0);
Thing is that I don't get any broadcast messages to that window... ;)

你的怀疑是正确的。仅消息窗口（通过为
CreateWindowEx函数的hwndParent参数指定HWND_MESSAGE创建的窗口）不会接收广播通知：参考：MSDN
Your suspicions are correct. Message-only windows (those created by specifying
HWND_MESSAGEfor thehwndParentparameter of theCreateWindowExfunction) do not receive broadcast notifications:Reference: MSDN
