碰到这种问题， 怎么解决？

[富莱工作室]

SystemParametersInfo(SPI_SETSWITCHTASKDISABLE,FALSE,NULL,0);
SPI_SETSWITCHTASKDISABLE' : undeclared identifier

而在MSDN中：

SPI_SETSWITCHTASKDISABLE
Windows NT 5.0 and later: Enables or disables ALT+TAB and ALT+ESC task switching. Set the uiParam parameter to 1 to enable the feature, or zero to disable it. By default, task switching is enabled.

我系统为WINXP， 环境VC6.0, 怎样上述代码编译成功？
