这几天一直在看计算机方面的书,准备考试软件工程师,但是看了看书,太恐怖了,很多我都不会,但是里面提醒了一个内容就是必须会使用一种语言(c++,java等)来编写程序。刚好今天看了一个杂志,里面有一片文章很好,我就开始学习了,所以就写了仿效写了下面的内容。

该工具是用来判断你是否具有管理员权限的工具,代码我就贴在这里。

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

BOOL IsAdmin(void)
{
 HANDLE hAccessToken;
 BYTE *InfoBuffer;
 PTOKEN_GROUPS ptgGroups;

 DWORD dwInfoBufferSize;
 PSID psidAdministrators;

 SID_IDENTIFIER_AUTHORITY sidNtAuthority=SECURITY_NT_AUTHORITY;
 UINT i;

 BOOL bRet=FALSE;

 if(!OpenProcessToken(GetCurrentProcess(),TOKEN_QUERY,&hAccessToken))
  InfoBuffer=new BYTE[1024];
 if(!InfoBuffer)
  goto cleanup;
 
 bRet=GetTokenInformation(hAccessToken,TokenGroups,InfoBuffer,1024,&dwInfoBufferSize);
 
 CloseHandle(hAccessToken);
 if(!bRet)
  goto cleanup;
 if(!AllocateAndInitializeSid(&sidNtAuthority,
         2,
         SECURITY_BUILTIN_DOMAIN_RID,
         DOMAIN_ALIAS_RID_ADMINS,
         0,0,0,0,0,0,
         &psidAdministrators));
  goto cleanup;
 
 bRet=FALSE;

 ptgGroups=(PTOKEN_GROUPS)InfoBuffer;
 
 for(i=0;i < ptgGroups-> GroupCount;i++)
 {
  if(EqualSid(psidAdministrators,ptgGroups->Groups[i].Sid))
  {
   bRet=TRUE;
   break;
  }

 }
 
 FreeSid(psidAdministrators);

cleanup:
 if(InfoBuffer)
  delete InfoBuffer;
 
 return bRet;
}

main()
{
 printf("+------------------------------------+/n");
    printf("|    ChkAdinistrator v0.1            |/n");
    printf("|      Write By AloneSword          |/n");
    printf("|      2005-9-14                    |/n");
    printf("|      thx to sinister              |/n");
 printf("| http://blog.csdn.net/alonesword/  |/n");
    printf("+-----------------------------------+/n");   
 if(IsAdmin) printf("You have got the Administrators rights./n");
 else printf("Sorry,administrator is not you./n");
}
