hi.

i want to get the time when the current user login system.

i use IADsUser::get_LastLogin(),but the ADsGetObject return a error code.

i find the code from a demo that download from this Website,and My operating system is win7.

C++

IADsWinNTSystemInfo *pNTsys;
	HRESULT hr = CoCreateInstance(CLSID_WinNTSystemInfo,
                              NULL,
                              CLSCTX_INPROC_SERVER,
                              IID_IADsWinNTSystemInfo,
                              (void**)&pNTsys);
	pNTsys->AddRef();

	BSTR bstrCompName;
	pNTsys->get_ComputerName(&bstrCompName);
	CString cscompName=bstrCompName;
	SysFreeString(bstrCompName);

	BSTR bstrDomainName;
	pNTsys->get_DomainName(&bstrDomainName);
	CString CSDomainName=bstrDomainName;
	SysFreeString(bstrDomainName);

	pNTsys->Release();

	//From ADSPath
	ADSPath.Format("WinNT://%s/%s",CSDomainName,cscompName);

	//Get the container object
        //*****************here get error code group not be found
	hr=ADsGetObject(ADSPath.AllocSysString(),IID_IADsContainer,(void **)&pUsers);

I think the AD stuff is only for use on a domain controller (?).

Here is an extract of some code I use for login time (sorry it is editted without compile if it has syntax errors):

C++

#include <Ntsecapi.h>

// [link to secur32.lib]


BOOL GetLogonLUID (LUID *pLuid)
{
    BOOL bSuccess = FALSE;
    HANDLE hThread = NULL;
    TOKEN_STATISTICS ts = {0};
    DWORD cbReturnLength = sizeof(TOKEN_STATISTICS);

    bSuccess = OpenProcessToken (GetCurrentProcess(), TOKEN_QUERY, &hThread);
    if (bSuccess)
    {
        bSuccess = GetTokenInformation (hThread, TokenStatistics, &ts, sizeof(TOKEN_STATISTICS), &cbReturnLength);
        if (bSuccess)
            *pLuid = ts.AuthenticationId;
    }
    if (hThread)
        CloseHandle (hThread);

    return bSuccess;
}

SYSTEMTIME& GetLoginTime()
{
    static SYSTEMTIME st = {0};
    FILETIME ft = {0};
    LUID LogonLuid = {0};
    PSECURITY_LOGON_SESSION_DATA pLogonSessionData = NULL;

    GetLogonLUID (&LogonLuid);
    NTSTATUS ntStatus = LsaGetLogonSessionData (&LogonLuid, &pLogonSessionData);
    if (ntStatus == 0)
    {
        if (pLogonSessionData->LogonTime.QuadPart)
        {
            FileTimeToLocalFileTime ((const FILETIME *)&pLogonSessionData->LogonTime, &ft);
            FileTimeToSystemTime (&ft, &st);
        }
    }
    if (pLogonSessionData)
        LsaFreeReturnBuffer(pLogonSessionData);

    return st;
}
