The SetFocus function sets the keyboard focus to the specified window. The window must be associated with the calling thread”s message queue.
HWND SetFocus(
HWND hWnd // handle to window to receive focus
);
Parameters
hWnd
Handle to the window that will receive the keyboard input. If this parameter is NULL, keystrokes are ignored.
Return Values
If the function succeeds, the return value is the handle to the window that previously had the keyboard focus. If the hWnd parameter is invalid or the window is not associated with the calling thread”s message queue, the return value is NULL. To get extended error information, callGetLastError.
Remarks
The SetFocus function sends a WM_KILLFOCUS message to the window that loses the keyboard focus and a WM_SETFOCUS message to the window that receives the keyboard focus. It also activates either the window that receives the focus or the parent of the window that receives the focus.
If a window is active but does not have the focus, any key pressed will produce the WM_SYSCHAR, WM_SYSKEYDOWN, or WM_SYSKEYUP message. If the VK_MENU key is also pressed, the lParam parameter of the message will have bit 30 set. Otherwise, the messages produced do not have this bit set.
By using the AttachThreadInput function, a thread can attach its input processing to another thread. This allows a thread to call SetFocus to set the keyboard focus to a window associated with another thread”s message queue.
Windows CE: Do not use the SetFocus function to set the keyboard focus to a window associated with another thread”s message queue. There is one exception. If a window on one thread is the child of the window on the other thread, or if the windows are siblings of the same parent, the thread associated with one window can set the focus to the other window even though it belongs to a different thread. In this case, there is no need to call AttachThreadInput first.

Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.

有很多游戏利用传说中的DX驱动，例如说赛车类的游戏，直接从键盘鼠标接收消息，不从操作系统接收消息，FLASH是怎么实现的，不清楚，本人也想找个师傅，网上也没找到相关的文章，只凭空猜的！

The ScreenToClient function converts the screen coordinates of a specified point on the screen to client coordinates.
BOOL ScreenToClient(
HWND hWnd, // window handle for source coordinates
LPPOINT lpPoint // address of structure containing coordinates
);
Parameters
hWnd
Handle to the window whose client area will be used for the conversion.
lpPoint
Pointer to a POINT structure that contains the screen coordinates to be converted.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Windows NT: To get extended error information, callGetLastError.
Remarks
The function uses the window identified by the hWnd parameter and the screen coordinates given in the POINT structure to compute client coordinates. It then replaces the screen coordinates with the client coordinates. The new coordinates are relative to the upper-left corner of the specified window”s client area.
The ScreenToClient function assumes the specified point is in screen coordinates.
