RegisterHotKey函数解决办法

RegisterHotKey函数
在OnCreat事件里加入
RegisterHotKey(m_hWnd,1001,MOD_CONTROL|MOD_SHIFT|MOD_ALT,VK_F10);
在OnDestroy事件里加入
UnregisterHotKey(   m_hWnd,   1001);  

上面那些函数里的   1001   是什么参数?

------解决方案--------------------
BOOL RegisterHotKey(
HWND hWnd, // window to receive hot-key notification
int id, // identifier of hot key
UINT fsModifiers, // key-modifier flags
UINT vk // virtual-key code
);

id
Specifies the identifier of the hot key. No other hot key in the calling thread should have the same identifier. An application must specify a value in the range 0x0000 through 0xBFFF. A shared dynamic-link library (DLL) must specify a value in the range 0xC000 through 0xFFFF (the range returned by theGlobalAddAtom function). To avoid conflicts with hot-key identifiers defined by other shared DLLs, a DLL should use the GlobalAddAtom function to obtain the hot-key identifier.
