我作了一个钩子
截获鼠标消息
因为要全屏
所以我分别截获了WM_LBUTTONDOWN,WM_NCLBUTTONDOWN,WM_LBUTTONU,WM_NCLBUTTONUP
但是产生的问题是当鼠标点在任务栏上的时候,截获不了
有没有什么办法可以截获所有的鼠标down/up消息,不管点在那里
谢谢 【 在 xler (堕落恶魔·爱神仙mm) 的大作中提到: 】
: WM_NCHITTEST 回答:
The WM_NCHITTEST message is sent to a window when the cursor moves, or when
a mouse button is pressed or released.
这个消息包括了所有的鼠标消息。
当一个消息产生后,可以从中间剔除移动消息,在客户区和非客户区的消息。
可是剩下的任务栏上的右击还是左击或者是中间的消息怎么能区分那??

The SetCapture function sets the mouse capture to the specified window belonging to the current thread. Once a window has captured the mouse, all mouse input is directed to that window, regardless of whether the cursor is within the borders of that window. Only one window at a time can capture the mouse. If the mouse cursor is over a window created by another thread, the system will direct mouse input to the specified window only if a mouse button is down. HWND SetCapture(
HWND hWnd // handle to window
);
Parameters
hWnd
[in] Handle to the window in the current thread that is to capture the mouse.
Return Values
The return value is a handle to the window that had previously captured the mouse. If there is no such window, the return value is NULL. Res
Only the foreground window can capture the mouse. When a background window attempts to do so, the window receives messages only for mouse events that occur when the cursor hot spot is within the visible portion of the window. Also, even if the foreground window has captured the mouse, the user can still click another window, bringing it to the foreground. When the window no longer requires all mouse input, the thread that created the window should call the ReleaseCapture function to release the mouse. This function cannot be used to capture mouse input meant for another process. When the mouse is captured, menu hotkeys and other keyboard accelerators do not work. Windows 95: Calling SetCapture causes the window that is losing the mouse capture to receive a WM_CAPTURECHANGED message.Requirements
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
