Parameters

idlName

The name of the IDL interface to be narrowed to, in the form "module/interface", where module is the IDL module name and interface is the IDL interface name.

Examples

Example 1

This example calls Orb.resolve_initial_references to obtain a proxy for the SSL service provider, then calls Object.Narrow_ to narrow to the CtsSecurity::SSLServiceProvider interface:

Dim orbRef As JaguarTypeLibrary.ORB
Dim ssp As CtsSecurity.SSLServiceProvider
Dim CORBAObj As Object 

' Initialize the ORB
Set orbRef = New JaguarTypeLibrary.ORB
orbRef.Init ("")

' Get a proxy for the SSLServiceProvider
Set CORBAObj = _
    orbRef.resolve_initial_references("SSLServiceProvider")
Set ssp = CORBAObj.Narrow_("CtsSecurity/SSLServiceProvider")
