这篇文章主要介绍了VC判断进程是否具有administrator权限的方法,在Windows应用程序设计中具有一定的实用价值,需要的朋友可以参考下

本文实例讲述了VC判断进程是否具有admin权限的方法。是的话返回TRUE，否则为FALSE。分享给大家供大家参考。具体实现方法如下：

复制代码代码如下:

	static BOOL IsAdmin(void) 

	{ 

	     HANDLE                   hAccessToken; 

	     BYTE                     InfoBuffer[1024];    

	     PTOKEN_GROUPS            ptgGroups; 

	     DWORD                    dwInfoBufferSize; 

	     PSID                     psidAdministrators; 

	     SID_IDENTIFIER_AUTHORITY siaNtAuthority = SECURITY_NT_AUTHORITY; 

	     UINT                     i; 

	     BOOL                     bRet = FALSE; 

	     if(!OpenProcessToken(GetCurrentProcess(),TOKEN_QUERY,&hAccessToken))

	        return bRet;          

	     bRet = GetTokenInformation(hAccessToken, TokenGroups, InfoBuffer, 1024, &dwInfoBufferSize);

	     CloseHandle(hAccessToken); 

	     if(!bRet) 

	        return bRet;

	     if(!AllocateAndInitializeSid(&siaNtAuthority, 

	                                  2, 

	                                  SECURITY_BUILTIN_DOMAIN_RID, 

	                                  DOMAIN_ALIAS_RID_ADMINS, 

	                                  0,0,0,0,0,0, 

	                                  &psidAdministrators))          

	        return FALSE;                                 

	     bRet = FALSE;    

	     ptgGroups = (PTOKEN_GROUPS)InfoBuffer; 

	     for(i=0;i<ptgGroups->GroupCount;i++)      

	         if(EqualSid(psidAdministrators,ptgGroups->Groups[i].Sid))       

	             bRet = TRUE;                 

	     FreeSid(psidAdministrators);  

	     return bRet;

	}
