Re:一个小问题，如何获得OS的版本及使用的语言
Getting the System Version
The 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>
#include <stdio.h>
#define BUFSIZE 80
int main()
{
OSVERSIONINFOEX osvi;
BOOL bOsVersionInfoEx;
// Try calling GetVersionEx using the OSVERSIONINFOEX structure.
// If that fails, try using the OSVERSIONINFO structure.
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osvi)) )
{
osvi.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);
if (! GetVersionEx ( (OSVERSIONINFO *) &osvi) )
return FALSE;
}

Verifying the System Version
This topic contains three examples. They determine whether the application is running on the following systems:
Windows 2000, Service Pack 1 or later
Windows 2000 Professional or Windows XP
Terminal Services
The main steps in each example are as follows:
Set the appropriate values in the OSVERSIONINFOEX structure
Setting the appropriate condition mask using the VER_SET_CONDITION macro
Call the VerifyVersionInfo function to perform the test.
The following example determines whether the application is running on Windows 2000 Service Pack 1 or later.
BOOL Is_Win2000_SP1_or_Later ()
{
OSVERSIONINFOEX osvi;
DWORDLONG dwlConditionMask = 0;
// Initialize the OSVERSIONINFOEX structure.
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osvi.dwMajorVersion = 5;
osvi.dwMinorVersion = 0;
osvi.wServicePackMajor = 1;
// Initialize the condition mask.
VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION,
VER_GREATER_EQUAL );
VER_SET_CONDITION( dwlConditionMask, VER_MINORVERSION,
VER_GREATER_EQUAL );
VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMAJOR,
VER_GREATER_EQUAL );
// Perform the test.
return VerifyVersionInfo(
&osvi,
VER_MAJORVERSION | VER_MINORVERSION | VER_SERVICEPACKMAJOR,
dwlConditionMask);
}
Testing for other conditions involves a simple modification to this code. For example, the following code verifies that the application is running on Windows 2000 Professional or Windows XP.
BOOL Is_Win2000_Professional ()
{
OSVERSIONINFOEX osvi;
DWORDLONG dwlConditionMask = 0;
// Initialize the OSVERSIONINFOEX structure.
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osvi.dwMajorVersion = 5;
osvi.wProductType = VER_NT_WORKSTATION;
// Initialize the condition mask.
VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION,
VER_GREATER_EQUAL );
VER_SET_CONDITION( dwlConditionMask, VER_PRODUCT_TYPE,
VER_EQUAL );
// Perform the test.
return VerifyVersionInfo(
&osvi,
VER_MAJORVERSION | VER_PRODUCT_TYPE,
dwlConditionMask);
}
Finally, the following example tests whether Terminal Services is installed.
BOOL Is_Terminal_Services ()
{
OSVERSIONINFOEX osvi;
DWORDLONG dwlConditionMask = 0;
// Initialize the OSVERSIONINFOEX structure.
ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osvi.wSuiteMask = VER_SUITE_TERMINAL;
// Initialize the condition mask.
VER_SET_CONDITION( dwlConditionMask, VER_SUITENAME,
VER_AND );
// Perform the test.
return VerifyVersionInfo(
&osvi,
VER_SUITENAME,
dwlConditionMask);
}
