The GetTree method enables an ASP Web page to obtain the values associated with a set of subnodes beneath a specified root SNMP OID.
Syntax
HRESULT GetTree(
[in] BSTR varTree,
[out] VARIANT *varValue
);
Parameters
varTree [in]
Caller-supplied string identifying a root SNMP OID.
varValue [out]
Caller-supplied location to receive the address of a two-dimensional array containing SNMP OID strings and associated values.
Return value
Win32 error codes can also be returned.
| Return code | Description |
|---|---|
| S_OK | The operation succeeded. |
| E_FAIL | The ISNMP::Open method has not been called. |
| E_INVALIDARG | The specified SNMP OID is not valid. |

VBScript example
This method calls the SnmpMgrRequest function to obtain the SNMP OID values for the subnodes.
The ISNMP::Open method must be called before the ISNMP::GetTree method can be called.
Dim StrIP, strCommunity, objSNMP, OIDValueArray
strIP = Session("MS_IPaddress")
strCommunity = Session ("MS_Community")
Set objSNMP = Server.CreateObject("OlePrn.OleSNMP")
objSNMP.Open strIP, strCommunity, 2, 1000
OIDValueArray = objSNMP.GetTree ("43.18.1.1.2")
