象这样的一些没有包括在win32api.txt的参数只能从VC++的头文件中找，下面就是头文件中部分VB没有包括的常数的定义： 
    #if(WINVER >= 0x0500) 
    #define SPI_GETMOUSESPEED 112 
    #define SPI_SETMOUSESPEED 113 
    #define SPI_GETSCREENSAVERRUNNING 114 
    #endif /* WINVER >= 0x0500 */ 
     
    #if(WINVER >= 0x0500) 
    #define SPI_GETACTIVEWINDOWTRACKING 0x1000 
    #define SPI_SETACTIVEWINDOWTRACKING 0x1001 
    #define SPI_GETMENUANIMATION 0x1002 
    #define SPI_SETMENUANIMATION 0x1003
