IXMLDOMImplementation.hasFeature (Visual Basic .NET)

The hasFeature method returns a Boolean value indicating whether the specified version of the implementation supports the specified feature.


  bValue = IXMLDOMImplementation
  strFeature As String,
  strVersion As String



[in] String that specifies the feature to test. In Level 1, valid feature values are "XML," "DOM," and "MS-DOM" (not case-sensitive).


[in] String that specifies the version number to test. If the string is empty, the method tests for implementation of the feature in all versions. In Level 1, "1.0" is the valid version value.

Return Values

Returns True if the specified feature is implemented, and False otherwise.


In the Windows Media Services SDK implementation of the XML DOM, this property will always return False.

Dim Server As New WMSServerClass()
Dim Playlist As IXMLDOMDocument

' Check whether a feature is implemented or not.
bool = Playlist.implementation.hasFeature("DOM", "1.0")
Exit Sub
