SelectNode Method

Used to select individual nodes in the loaded MIB module(s).

Syntax

int SelectNode(const QString& qsSelector);

Remarks

SelectNode is used for selecting individual nodes and should be called before querying node information.

The Selector parameter can be a label such as "internet", an OID such as "1.3.6.4", a combination of the two: "iso.3.dod.internet", or a label in a particular module such as "RFC1213-MIB!interfaces".

Either '.' or ':' can be used to separate SubIds. If a SubId starts with "0x" or follows the ":" separator then its hexadecimal value is used. For instance, "0x1.0x3.0x6.0x1A" is the same as "1:3:6:1A".

All properties and methods of the class will operate on the selected node. For example, calling ListSuccessors will only list the successors of the selected node.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
