Question

我想让一个使用<代码>的集团的用户参与进来。 NetGroupGetUsers function.

DWORD dwError = 0;
NET_API_STATUS nStatus;
LPDWORD entriesread=0;
LPDWORD totalentries=0;
LPBYTE *buff;
nStatus=NetGroupGetUsers(NULL,L"Users",0,buff,MAX_PREFERRED_LENGTH,
                          entriesread,totalentries,NULL);

(一) 使用这个错误;

xC0000005: Access violation reading location 0xffffffffffffffff.

如何在什么时候奏效? 同时,我也试图这样做;

GROUP_USERS_INFO_0 *buff;
nStatus=NetGroupGetUsers(NULL,L"Users",0,(LPBYTE*)&buff,MAX_PREFERRED_LENGTH,
entriesread,totalentries,NULL);

但也有同样的错误。

EDIT:NStatus Value is NERR_group Notfound i 认为侵犯准入的原因正试图读出实际上确定的uff。

EDIT2:i利用这一功能Net LocalGroupGet Memberss。现在它取得了成功,但<代码>buff->grui0_name毫无意义。有一个名为“ali”的用户,但buff->grui0_name的价值只是“d”。 WHAT AM I DOING WRONG?

最后一部法典;

LPCWSTR TargetGroup = L"group1";

DWORD dwError = 0;
NET_API_STATUS stat;

GROUP_USERS_INFO_0 *buff;
LPDWORD entriesread=new DWORD;
LPDWORD totalentries=new DWORD;

stat=NetGroupGetUsers(NULL,TargetGroup,0,(LPBYTE *)&buff,MAX_PREFERRED_LENGTH,
                          entriesread,totalentries,NULL);

表2

stat=NetLocalGroupGetMembers(NULL,TargetGroup,0,(LPBYTE *)&buff,
                  MAX_PREFERRED_LENGTH,entriesread,totalentries,NULL);

请帮助......

Answer 1

LPCWSTR TargetGroup = L"group1";

NET_API_STATUS stat;

LOCALGROUP_MEMBERS_INFO_1 *buff;
LPDWORD entriesread=new DWORD;
LPDWORD totalentries=new DWORD;

stat=NetLocalGroupGetMembers(NULL,TargetGroup,1,(LPBYTE *)&buff,
                        MAX_PREFERRED_LENGTH,entriesread,totalentries,NULL);



wprintf(buff->lgrmi1_name);

该法典现在起作用。感谢大家。

页: 1 你应该写

GROUP_USERS_INFO_0 *buff;
... NetGroupGetUsers(..., (LPBYTE*)&buff, ...);

otherwise you re telling NetGroupGetUsers to write the results to a garbage location. Note that the bufptr parameter is documented as [out]. That means that it is the caller s responsibility to specify where the result should go. There s more to calling a function than just getting the types to match.

我感到吃惊的是,你没有从编辑处得到“使用初步变数”的报警。

Answer 3

这里没有新版本:

LPCWSTR TargetGroup = L"group1";

NET_API_STATUS stat;

LOCALGROUP_MEMBERS_INFO_1 *buff;
DWORD entriesread;
DWORD totalentries;

stat = NetLocalGroupGetMembers(NULL,TargetGroup,1,(LPBYTE *)&buff,
    MAX_PREFERRED_LENGTH,&entriesread,&totalentries,NULL);

wprintf(buff->lgrmi1_name);
