问题描述

我使用GetUserName（）METHOD，但它返回的用户名是SYSTEM过程中的SYSTEM。我如何在SYSTEM进程中获取活动用户名？ This is My CODE：

I have used GetUserName() METHOD , but the username it returned is 'SYSTEM' in a SYSTEM process.How can I get the active username in a SYSTEM process? THIS IS MY CODE:

void getComputerUsername(char * username,char * domainname)
{
 HANDLE hp , htoken;
 char buff[1024];
 unsigned long size = 1024;

 TOKEN_USER *tuser;
 PSID sid;
 TCHAR * user = new TCHAR[256];
 TCHAR * domain=new TCHAR[256];
 SID_NAME_USE snu;

 hp = htoken = INVALID_HANDLE_VALUE;
 hp = GetCurrentProcess();
 if(OpenProcessToken(hp, TOKEN_QUERY, &htoken))
 {
     if(GetTokenInformation(htoken, TokenUser, (void*)buff, size, &size))
 {
     tuser = (TOKEN_USER*)buff;
     sid = tuser->User.Sid;
     size = 256;
     if(LookupAccountSid(NULL, sid, user, &size, domain, &size, &snu))
     {
    int iLength = WideCharToMultiByte(CP_ACP, 0, user, -1, NULL, 0, NULL, NULL);  
    WideCharToMultiByte(CP_ACP, 0, user, -1, username, iLength, NULL, NULL);   

    iLength = WideCharToMultiByte(CP_ACP, 0, domain, -1, NULL, 0, NULL, NULL);  
    WideCharToMultiByte(CP_ACP, 0, domain, -1, domainname, iLength, NULL, NULL);  
           //strcpy( user,username);
     }
 }
 }

}

推荐答案

您需要枚举所有正在运行的进程，使用 EnumProcesses

You need to enumerate through all the running processes using EnumProcesses
