一、MOUSEHOOKSTRUCT structure重要

typedef struct tagMOUSEHOOKSTRUCT {
  POINT     pt;
  HWND      hwnd;
  UINT      wHitTestCode;
  ULONG_PTR dwExtraInfo;
} MOUSEHOOKSTRUCT, *PMOUSEHOOKSTRUCT, *LPMOUSEHOOKSTRUCT;

二、MSLLHOOKSTRUCT structure重要

typedef struct tagMSLLHOOKSTRUCT {
  POINT     pt;
  DWORD     mouseData;
  DWORD     flags;
  DWORD     time;
  ULONG_PTR dwExtraInfo;
} MSLLHOOKSTRUCT, *PMSLLHOOKSTRUCT, *LPMSLLHOOKSTRUCT;

mouseData
Type: DWORD 解释（32位）

如果消息是类型是 WM_MOUSEWHEEL… 如果消息是类型是WM_XBUTTONDOWN, WM_XBUTTONUP,
WM_XBUTTONDBLCLK, WM_NCXBUTTONDOWN, WM_NCXBUTTONUP, or
WM_NCXBUTTONDBLCLK, 那么高位判断哪个按键。

举例用法：监控鼠标侧键XBUTTON1

LRESULT CALLBACK MouseHook(int nCode,WPARAM wParam,LPARAM lParam) {
	LPMSLLHOOKSTRUCT pMouseHook = (MSLLHOOKSTRUCT*)lParam; 
	if (nCode >= 0)  {
		 If (wParam==WM_XBUTTONDOWN && HIWORD(pMouseHook->mouseData)==XBUTTON1) {
		 		...自己的代码；
		 		return TRUE;
		  }
		if (wParam == WM_XBUTTONUP && HIWORD(pMouseHook->mouseData)==XBUTTON1) { 
   				 //写上自己代码
				return TRUE;
    	}
		if (wParam == WM_XBUTTONDOWN && HIWORD(pMouseHook->mouseData)==XBUTTON2) {
			    //写上自己代码
			    return TRUE;
		}
	｝
		return CallNextHookEx(glhHook, nCode, wParam, lParam);
}

MSG structure

typedef struct tagMSG {
  HWND   hwnd;
  UINT   message;
  WPARAM wParam;
  LPARAM lParam;
  DWORD  time;
  POINT  pt;
} MSG, *PMSG, *LPMSG;

RECT structure

typedef struct _RECT {
  LONG left;
  LONG top;
  LONG right;
  LONG bottom;
} RECT, *PRECT;
