Question

请问,如何判断OS是XP,Home版或者Professional版?

Answer 1

如果告诉我在Installshield中的方法更好,我用的是IS6.22

GetVersionEx可以的哦Getting the System VersionThe following example uses the GetVersionEx function to display the version of the currently running operating system. Relying on version information is not the best way to test for a feature. Instead, refer to the documentation for the feature of interest. For more information on common techniques for feature detection, see Operating System Version. If you must require a particular operating system, be sure to use it as a minimum supported version, rather than design the test for the one operating system. This way, your detection code will continue to work on future versions of Windows. #include <windows.h>

Answer 5

我用的IS6.2中系统常量SYSINFO没有XP相关的.只有98,NT,2000,怎么办?
