vc 获取系统版本

版本帮助程序函数

#include <VersionHelpers.h>
 
if (!IsWindows8OrGreater())
{
   MessageBox(NULL, "You need at least Windows 8", "Version Not Supported", MB_OK);
}

GetVersionEx函数可能在Win8.1之后会取消,推荐使用Version Helper APIs

char szOSName[40] = { 0 };

	DWORD  dwMajorVersion;
	DWORD   dwMinorVersion;
	DWORD  dwBuildNumber;
	DWORD  dwPlatformId;
	OSVERSIONINFO osvi;//定义OSVERSIONINFO数据结构对象
	memset(&osvi, 0, sizeof(OSVERSIONINFO));//开空间 
	osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);//定义大小 
	GetVersionEx(&osvi);//获得版本信息 
	dwMajorVersion = osvi.dwMajorVersion;//主版本号
	dwMinorVersion = osvi.dwMinorVersion;//副版本
	dwBuildNumber = osvi.dwBuildNumber;//创建号
	dwPlatformId = osvi.dwPlatformId;//ID号
	char swVersion[10] = { 0 };
	sprintf(swVersion, "%d.%d", dwMajorVersion, dwMinorVersion);
	// dwVesion=atoi(swVersion);  

	//if (!strcmp(swVersion, "4.0"))   strcpy(szOSName, "win95");    //win95    
	//if (!strcmp(swVersion, "4.1")) strcpy(szOSName, "win98");     //win98 
	//if (!strcmp(swVersion, "4.9")) strcpy(szOSName, "win_me");     // win_me 
	//if (!strcmp(swVersion, "3.51")) strcpy(szOSName, "win_Nt_3_5");  //win_Nt_3_5    
	//if (!strcmp(swVersion, "5.0"))  strcpy(szOSName, "win2000");    //win2000   
	//if (!strcmp(swVersion, "5.1"))   strcpy(szOSName, "win_xp");    //win_xp 
	//if (!strcmp(swVersion, "5.2"))  strcpy(szOSName, "win2003");    // win2003 
	//if (!strcmp(swVersion, "6.6"))   strcpy(szOSName, "vista");    //vista
	//if (!strcmp(swVersion, "6.1"))   strcpy(szOSName, "win7");     // win7 
	//if (!strcmp(swVersion, "6.1"))   strcpy(szOSName, "win8");      // win8 

	if (!strcmp(swVersion, "6.1")) {
		MessageBox(NULL, "win 7", "current version中文", MB_OK);
	}// win7
