[转]C++ 获取系统版本号

VC6

原文:https://www.cnblogs.com/Bachelor/p/11290159.html

因用到系统版本号，区别对待。

    // 5.0 Windows 2000";
    // 5.1 Windows XP";
    // 5.2 Windows 2003";
    // 6.0 Windows Vista";
    // 6.1 Windows 7";
    // 6.2 Windows 8";
    // 6.3 Windows 8.1";
    // 10.0 Windows 10";
    //其他版本

方法1：

此方法是测下来 XP、win7、win10都通过的方法。

1. DWORD Major,Minor,Build;
   
2. void GetOSVersion1()
   
3. {
   
4.     _asm
   
5.     {
   
6.         pushad
   
7.         mov ebx, fs:[0x18]; get self pointer from TEB
   
8.         mov eax, fs:[0x30]; get pointer to PEB / database
   
9.         mov ebx, [eax + 0A8h]; get OSMinorVersion
   
10.         mov eax, [eax + 0A4h]; get OSMajorVersion
    
11.         mov Minor, ebx
    
12.         mov Major, eax
    
13.         popad
    
14.     }
    
15.     Build = 0;
    
16. }

复制代码

方法2：

1. DWORD Major,Minor,Build;
   
2. 
   
3. typedef NTSTATUS(WINAPI* _NtQueryInformationProcess)
   
4. (_In_ HANDLE ProcessHandle, _In_ PROCESSINFOCLASS ProcessInformationClass,
   
5.     _Out_ PVOID ProcessInformation, _In_ ULONG ProcessInformationLength, _Out_opt_ PULONG ReturnLength);
   
6. _NtQueryInformationProcess NtQueryInformationProcess_;
   
7. 
   
8. DWORD GetProcessPEBAddress(HANDLE hProc)
   
9. {
   
10.     PROCESS_BASIC_INFORMATION peb;
    
11.     DWORD tmp;
    
12.     NtQueryInformationProcess_ = (_NtQueryInformationProcess)GetProcAddress(GetModuleHandle(L"ntdll.dll"), "NtQueryInformationProcess");
    
13.     NtQueryInformationProcess_(hProc, ProcessBasicInformation, &peb, sizeof(PROCESS_BASIC_INFORMATION), &tmp);
    
14.     return (DWORD)peb.PebBaseAddress;
    
15. }
    
16. 
    
17. void GetOSVersionByHandle(HANDLE handle)
    
18. {
    
19.     DWORD pebAddress = GetProcessPEBAddress(handle);
    
20.     DWORD OSMajorVersionAddress = pebAddress + 0x0a4;
    
21.     DWORD OSMinorVersionAddress = pebAddress + 0x0a8;
    
22.     DWORD OSBuildNumberAddress = pebAddress + 0x0ac;
    
23.     ReadProcessMemory(handle, (void*)OSMajorVersionAddress, &Major, sizeof(Major), 0);
    
24.     ReadProcessMemory(handle, (void*)OSMinorVersionAddress, &Minor, sizeof(Minor), 0);
    
25.     ReadProcessMemory(handle, (void*)OSBuildNumberAddress, &Build, sizeof(Build), 0);
    
26. }
    
27. 
    
28. 
    
29. void GetOSVersion2()
    
30. {
    
31.     HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, GetCurrentProcessId());
    
32.     GetOSVersionByHandle(handle);
    
33. }

方法3：

GetVersionEx在win10版本以后，已经失效。

1. DWORD Major,Minor,Build;
   
2. 
   
3. void GetOSVersion3()
   
4. {
   
5.     OSVERSIONINFO osvi;                    //定义OSVERSIONINFO数据结构对象
   
6.     memset(&osvi, 0, sizeof(OSVERSIONINFO));        //开空间
   
7.     osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);    //定义大小
   
8.     GetVersionEx(&osvi);                    //获得版本信息
   
9. 
   
10.     Major = osvi.dwMajorVersion;
    
11.     Minor = osvi.dwMinorVersion;
    
12.     Build = osvi.dwBuildNumber;
    
13. }

系统版本号 分不出系统了, win2008 win2012server 那些呢
