VC如何注册多个热键？

#include<windows.h>
#include <stdio.h>
int main()
{
    RegisterHotKey(NULL,0x0001,MOD_CONTROL|MOD_ALT,'X');//注册热键
    RegisterHotKey(NULL,0x0002,MOD_CONTROL|MOD_ALT,'T');//注册热键
    MSG msg;
    while(GetMessage(&msg,NULL,0,0))//从消息队伍获取消息
    {
        if(msg.message==WM_HOTKEY)//热键消息
        {
            if(msg.wParam == 0x0002) printf("you press ctrl+alt+T hotkey\n");
            else if(MessageBox(NULL,"你确定要退出程序吗？","热键提示",MB_YESNO|MB_SYSTEMMODAL)==IDYES)
            {
                UnregisterHotKey(NULL,0x0001);//卸载热键
                UnregisterHotKey(NULL,0x0002);//卸载热键
                break;
            }
        }
    }
    return 0;
}
