一、得到OS版本信息
参考文章：https://www.cnblogs.com/VOIP/archive/2011/03/22/1990927.html
常用两个函数GetVersion和GetVersionEx。
GetVersion这个函数曾经困扰了很多程序员，其本来设计的是在DWORD返回值中用低位的那个字表示MS-DOS的版本号，高位的那个字表示Windows版本号。对于每个字来说，高位字节代表主要版本号，低位字节代表次要版本号。可是因为编写此函数的程序员犯了一个错误，使得此函数返回的Windows版本号颠倒了(即把主要版本号放到了低位字节，而次要版本号放到了高位字节)。当发现此错误的时候已经有很多程序员在使用这个函数了，Microsoft只好将错就错，直接把原来的API文档给改了过来。
为了解决GetVersion带来的问题，Microsoft后来开发了一个新的函数GetVersionEx，用它能够得到更详细的Windows系统的版本信息，下面我就写写GetVersionEx的使用方法。
函数原型：
BOOL GetVersionEx(POSVERSIONINFO pVersionInformation);
我们先来看看OSVERSIONINFOEX这个结构：
typedef struct { DWORD dwOSVersionInfoSize; //在使用GetVersionEx之前要将此初始化为结构的大小 DWORD dwMajorVersion; //系统主版本号 DWORD dwMinorVersion; //系统次版本号 DWORD dwBuildNumber; //系统构建号 DWORD dwPlatformId; //系统支持的平台(详见附1) TCHAR szCSDVersion[128]; //系统补丁包的名称 WORD wServicePackMajor; //系统补丁包的主版本 WORD wServicePackMinor; //系统补丁包的次版本 WORD wSuiteMask; //标识系统上的程序组(详见附2) BYTE wProductType; //标识系统类型(详见附3) BYTE wReserved; //保留,未使用 } OSVERSIONINFOEX, *POSVERSIONINFOEX;
这个结构在Windows 2000后出现，老版本的OSVERSIONINFO结构没有wServicePackMajor、wServicePackMinor、wSuiteMask、wProductType和wReserved这几个成员。
一个关于他的简单示例：
OSVERSIONINFO osvi; ZeroMemory(&osvi, sizeof(OSVERSIONINFO)); osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); GetVersionEx(&osvi); printf("OS Version: %d ", osvi.dwMajorVersion);
但是，这个函数有局限性，只适用于Win8.1以下的版本，如果是Win10就需要使用另外的方法。
判断版本信息如下：
#include <Windows.h> #include <string> #include <stdio.h> void getSystemName() { std::string vname; //先判断是否为win8.1或win10 typedef void(__stdcall*NTPROC)(DWORD*, DWORD*, DWORD*); HINSTANCE hinst = LoadLibrary("ntdll.dll"); DWORD dwMajor, dwMinor, dwBuildNumber; NTPROC proc = (NTPROC)GetProcAddress(hinst, "RtlGetNtVersionNumbers"); proc(&dwMajor, &dwMinor, &dwBuildNumber); if (dwMajor == 6 && dwMinor == 3) //win 8.1 { vname = "Microsoft Windows 8.1"; printf_s("此电脑的版本为:%s ", vname.c_str()); return; } if (dwMajor == 10 && dwMinor == 0) //win 10 { vname = "Microsoft Windows 10"; printf_s("此电脑的版本为:%s ", vname.c_str()); return; } //下面判断不能Win Server，因为本人还未有这种系统的机子，暂时不给出 //判断win8.1以下的版本 SYSTEM_INFO info; //用SYSTEM_INFO结构判断64位AMD处理器 GetSystemInfo(&info); //调用GetSystemInfo函数填充结构 OSVERSIONINFOEX os; os.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX); #pragma warning(disable:4996) if (GetVersionEx((OSVERSIONINFO *)&os)) { //下面根据版本信息判断操作系统名称 switch (os.dwMajorVersion) { //判断主版本号 case 4: switch (os.dwMinorVersion) { //判断次版本号 case 0: if (os.dwPlatformId == VER_PLATFORM_WIN32_NT) vname ="Microsoft Windows NT 4.0"; //1996年7月发布 else if (os.dwPlatformId == VER_PLATFORM_WIN32_WINDOWS) vname = "Microsoft Windows 95"; break; case 10: vname ="Microsoft Windows 98"; break; case 90: vname = "Microsoft Windows Me"; break; } break; case 5: switch (os.dwMinorVersion) { //再比较dwMinorVersion的值 case 0: vname = "Microsoft Windows 2000"; //1999年12月发布 break; case 1: vname = "Microsoft Windows XP"; //2001年8月发布 break; case 2: if (os.wProductType == VER_NT_WORKSTATION && info.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_AMD64) vname = "Microsoft Windows XP Professional x64 Edition"; else if (GetSystemMetrics(SM_SERVERR2) == 0) vname = "Microsoft Windows Server 2003"; //2003年3月发布 else if (GetSystemMetrics(SM_SERVERR2) != 0) vname = "Microsoft Windows Server 2003 R2"; break; } break; case 6: switch (os.dwMinorVersion) { case 0: if (os.wProductType == VER_NT_WORKSTATION) vname = "Microsoft Windows Vista"; else vname = "Microsoft Windows Server 2008"; //服务器版本 break; case 1: if (os.wProductType == VER_NT_WORKSTATION) vname = "Microsoft Windows 7"; else vname = "Microsoft Windows Server 2008 R2"; break; case 2: if (os.wProductType == VER_NT_WORKSTATION) vname = "Microsoft Windows 8"; else vname = "Microsoft Windows Server 2012"; break; } break; default: vname = "未知操作系统"; } printf_s("此电脑的版本为:%s ", vname.c_str()); } else printf_s("版本获取失败 "); } void main() { getSystemName(); system("pause"); }
可以得到正确的结果，包括Win10。
二、获取wlan自动配置服务状态
wlan自动配置服务(Wlan Autoconfig)是微软 Windows Vista以上版本操作系统的无线网卡配置服务。替代并增强了Windows XP/Windows server 2003中的Windows零配置服务（Wireless zero configuration）。
wlan自动配置服务的servicename是Wlansvc，Windows零配置服务的servicename是WZCSVC。服务状态三步走：OpenSCManager --> OpenService --> QueryServiceStatus。
服务器状态对应的值为
后续可以根据服务的状态进行相应的操作。
随便参考一个Windows服务运行状态的例子：
#include <iostream> #include <tchar.h> #include <Windows.h> using namespace std; /* 检查Windows服务状态信息 使用API: OpenSCManager OpenService QueryServiceStatusEx */ int main(void) { TCHAR szSvcName[] = _T("HistorySvr"); SC_HANDLE schSCManager = NULL; SC_HANDLE schService = NULL; SERVICE_STATUS_PROCESS ssStatus; DWORD dwOldCheckPoint = 0; DWORD dwStartTickCount = 0; DWORD dwWaitTime = 0; DWORD dwBytesNeeded = 0; // Get a handle to the SCM database. schSCManager = OpenSCManager( NULL, // local computer NULL, // ServicesActive database SC_MANAGER_ALL_ACCESS); // full access rights if (NULL == schSCManager) { printf("OpenSCManager failed (%d) ", GetLastError()); } // Get a handle to the service. schService = OpenService( schSCManager, // SCM database szSvcName, // name of service SERVICE_QUERY_STATUS | SERVICE_ENUMERATE_DEPENDENTS); // full access if (schService == NULL) { printf("OpenService failed (%d) ", GetLastError()); CloseServiceHandle(schSCManager); } // Check the status in case the service is not stopped. if (!QueryServiceStatusEx( schService, // handle to service SC_STATUS_PROCESS_INFO, // information level (LPBYTE) &ssStatus, // address of structure sizeof(SERVICE_STATUS_PROCESS), // size of structure &dwBytesNeeded ) ) // size needed if buffer is too small { printf("QueryServiceStatusEx failed (%d) ", GetLastError()); CloseServiceHandle(schService); CloseServiceHandle(schSCManager); } else { // Check if the service is already running. It would be possible // to stop the service here, but for simplicity this example just returns. printf("Service status: "); switch(ssStatus.dwCurrentState) { case SERVICE_STOPPED: case SERVICE_STOP_PENDING: printf("Stop"); break; case SERVICE_PAUSED: case SERVICE_PAUSE_PENDING: printf("Pause"); break; case SERVICE_CONTINUE_PENDING: case SERVICE_RUNNING: case SERVICE_START_PENDING: printf("Running"); break; } cout << endl; } cin.get(); return 0; }
OpenSCManager最后一个参数代表的意义：
