Topic Last Modified: 2006-06-13

The GetRootNode method obtains a root node object from a valid root URL.

Applies To

EXTV Interface

Syntax

Function GetRootNode(    ByVal URL As String) As RootNode
HRESULT GetRootNode
(
        BSTR URL,
        _RootNode** pVal
);

Parameters

  • URL
    A valid root URL to a root node. This URL must be Unicode transformation format (UTF) encoded or derived from a TNode object.
  • pVal

Return Value

Returns S_OK if successful, or an error value otherwise.

Remarks

This method does not extract a node from a URL pointing deeper in the hierarchy. The root node must exist in the RootNodes collection.

Example

The following example uses a TNode object to get the selected node's URL, obtains the root URL, and creates a root node object.


Dim rn As RootNode
Dim tn As TNode
Set tn = EXTV1.GetSelectedNode
Set rn = EXTV1.GetRootNode(tn.RootUrl)
MsgBox rn.url
