vc++学习(六)——代码学习

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");

}
