驗證系統版本

[ 使用 VerifyVersionInfo 函式來確認目前執行的作業系統不建議使用。 請改用 版本協助程式 API]

這包含使用 VerifyVersionInfo 函式來判斷應用程式是否在特定作業系統上執行的範例。

每個範例中的主要步驟如下：

1. 在 OSVERSIONINFOEX 結構中設定適當的值。
2. 使用 VER_SET_CONDITION 宏設定適當的條件遮罩。
3. 呼叫 VerifyVersionInfo 來執行測試。

範例 1

下列範例會判斷應用程式是在 Windows XP 上使用 Service Pack 2 (SP2) 或更新版本的 Windows 執行，例如 Windows Server 2003 或 Windows Vista。

#include <windows.h>
#include <stdio.h>

BOOL Is_WinXP_SP2_or_Later () 
{
   OSVERSIONINFOEX osvi;
   DWORDLONG dwlConditionMask = 0;
   int op=VER_GREATER_EQUAL;

   // Initialize the OSVERSIONINFOEX structure.

   ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
   osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
   osvi.dwMajorVersion = 5;
   osvi.dwMinorVersion = 1;
   osvi.wServicePackMajor = 2;
   osvi.wServicePackMinor = 0;

   // Initialize the condition mask.

   VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_MINORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMAJOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMINOR, op );

   // Perform the test.

   return VerifyVersionInfo(
      &osvi, 
      VER_MAJORVERSION | VER_MINORVERSION | 
      VER_SERVICEPACKMAJOR | VER_SERVICEPACKMINOR,
      dwlConditionMask);
}

void main()
{
    if(Is_WinXP_SP2_or_Later())
        printf("The system meets the requirements.\n");
    else printf("The system does not meet the requirements.\n");
}

範例 2

下列程式碼會驗證應用程式是在 Windows 2000 Server 或更新版本的伺服器上執行，例如 Windows Server 2003 或 Windows Server 2008。

#include <windows.h>
#include <stdio.h>

BOOL Is_Win_Server() 
{
   OSVERSIONINFOEX osvi;
   DWORDLONG dwlConditionMask = 0;
   int op=VER_GREATER_EQUAL;

   // Initialize the OSVERSIONINFOEX structure.

   ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
   osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
   osvi.dwMajorVersion = 5;
   osvi.dwMinorVersion = 0;
   osvi.wServicePackMajor = 0;
   osvi.wServicePackMinor = 0;
   osvi.wProductType = VER_NT_SERVER;

   // Initialize the condition mask.

   VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_MINORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMAJOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMINOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_PRODUCT_TYPE, VER_EQUAL );

   // Perform the test.

   return VerifyVersionInfo(
      &osvi, 
      VER_MAJORVERSION | VER_MINORVERSION | 
      VER_SERVICEPACKMAJOR | VER_SERVICEPACKMINOR |
      VER_PRODUCT_TYPE,
      dwlConditionMask);
}

void main()
{
    if(Is_Win_Server())
        printf("The system meets the requirements.\n");
    else printf("The system does not meet the requirements.\n");
}
