HRESULT put_NetAddresses
([in] VARIANT vNetAddresses);

 An array of NetAddress fields that represent the addresses by which this computer can be reached. NetAddress is a provider-specific BSTR composed of two substrings separated by a colon (":"). The left-hand substring indicates the address type, and the right-hand substring is a string representation of an address of that type. For example, TCP/IP addresses are of the form "IP:100.201.301.45. IPX type addresses are of the form "IPX:10.123456.80".

Remarks

Different providers may choose to expose different properties of a computer object. For more information, see ADSI System Providers.

You can discover what properties are supported by inspecting the mandatory and optional properties through its schema class. For more information, see the IADsClass interface.

To examine the status of a computer or to perform the shutdown operation across the network, you must use the IADsComputerOperations interface.

Example Code [Visual Basic]

The following Visual Basic code snippet examines computer properties supported by the ADSI WinNT provider.

Dim obj as IADs
Set obj = GetObject("WinNT://myMachine,computer")
If (obj.Class = "Computer") Then
    MsgBox "Computer owner: " & obj.owner
    MsgBox "Computer division: " & obj.Division
    MsgBox "Computer operatingSystem: " & obj.OperatingSystem
    MsgBox "Computer operating System Version: " & obj.OperatingSystemVersion
    MsgBox "Computer processor: " & obj.Processor
    MsgBox "Computer processor Count: " & obj.ProcessorCount
End If

Example Code [C++]

The following C++/C code snippet examines computer properties supported by the ADSI WinNT provider.

IADsComputer *pComp;
LPWSTR adspath = L"WinNT://kding1,computer";
HRESULT hr;

hr = ADsGetObject(adspath,IID_IADsComputer,(void**)&pComp);
if(FAILED(hr)) return hr;

BSTR bstr;
pComp->get_Owner(&bstr);
printf("Computer owner: %S\n",bstr);
SysFreeString(bstr);

pComp->get_OperatingSystem(&bstr);
printf("Operating System: %S\n",bstr);
SysFreeString(bstr);

pComp->Release();
