Question

VC 如何获取本机 域名 或 工作组

如题！！

Answer 1

1. 使用
int DimCount;
void main（）
｛
LPNETRESOURCE lpNetRC_p=NULL；
DimCount=0;
Enumerate(lpNetRC_p) ;

｝
2.回调函数

bool Enumerate(LPNETRESOURCE lpNetRC_p)
{
int UserCount=0;
HANDLE hEnum = 0;
DWORD dwScope = RESOURCE_GLOBALNET ;
DWORD dwType = RESOURCETYPE_ANY;

DWORD dwResult = WNetOpenEnum(
dwScope, // scope of enumeration
dwType, // resource types to list
0, // enumerate all resources or RESOURCEUSAGE_CONTAINER
lpNetRC_p, // pointer to resource structure (NULL at first time)
&hEnum // handle to resource
);

if( dwResult != NO_ERROR )
{
int re=GetLastError();

return FALSE;
}

DWORD dwBuffer = 16384 ; // 16K is reasonable size

DWORD dwEntries = 0xFFFFFFFF ; // enumerate all possible entries

LPNETRESOURCE lpBuffer;

// first allocate buffer for NETRESOURCE structures ...

lpBuffer=(LPNETRESOURCE)GlobalAlloc(GPTR,dwBuffer ) ;

dwResult = WNetEnumResource(hEnum,&dwEntries,lpBuffer,&dwBuffer);

if( dwResult == NO_ERROR )
{
for( register DWORD i = 0 ; i <dwEntries;i++)
{

// memcpy(&lpBuffer[i],&lpBuffer[i],sizeof(NETRESOURCE));

if(lpNetRC_p)
{
if(lpBuffer[i].dwDisplayType==RESOURCEDISPLAYTYPE_DOMAIN)
{
//这里就是得到获取本机 域名 或 工作组名并把它放到数组中
strcpy((char *)DimInfo[DimCount++].dimName,lpBuffer[i].lpRemoteName);

}
else
{ //这里就是得到的用户名并把它放到数组中

strcpy((char *)DimInfo[DimCount-1].User[UserCount++].UserName,lpBuffer[i].lpRemoteName+2);
if(UserCount>=20)UserCount=0;
}
}

DWORD a=lpBuffer[i].dwDisplayType,c=lpBuffer[i].dwUsage;

//RESOURCEUSAGE_CONTAINER == (lpBuffer[i].dwUsage & RESOURCEUSAGE_CONTAINER)
//上面的条件枚举所有的网络资源
if(a==6||a&RESOURCEDISPLAYTYPE_DOMAIN==RESOURCEDISPLAYTYPE_DOMAIN||c&RESOURCEUSAGE_CONTAINER==RESOURCEUSAGE_CONTAINER)
{
if(!Enumerate(&lpBuffer[i]))
{
return FALSE;
}
//strcpy((char *)User[UserCount++].UserName,lpBuffer[i].lpRemoteName+2);
//if(UserCount>=20)UserCount=0;
}
}
}
else if(dwResult != ERROR_NO_MORE_ITEMS)
{
return FALSE;
}

if(lpBuffer) GlobalFree((HGLOBAL) lpBuffer) ;
WNetCloseEnum(hEnum) ;

return TRUE;
}
