'Declaration
 
Public Function GetEnable( _
   ByVal Name As String _
) As Boolean

'Usage
 
Dim instance As FilterEnum
Dim Name As String
Dim value As Boolean
 
value = instance.GetEnable(Name)

public bool GetEnable( 
   string Name
)

 function Leadtools.Multimedia.FilterEnum.GetEnable( 
   Name 
)

public:
bool GetEnable( 
   String^ Name
)

Parameters

Name: A string that shows either the Display Name or Friendly Name of the filter. It is best to use "Display Name" since it is unique and no two filters can have the same Display Name. On the contrary, two or more filters can have have the same Friendly Name. When two or more filters have the same Friendly name, this function works on the first filter it internally enumerates having the specified friendly name.

Return Value

true if the filter is enabled or its merit is more than 0x200000 (MERIT_DO_NOT_USE); false, otherwise.

For more information, refer to the Microsoft documentation for DirectShow Merits http://msdn.microsoft.com/en-us/library/dd390674(VS.85).aspx http://msdn.microsoft.com/en-us/library/aa920889.aspx http://msmvps.com/blogs/chrisl/articles/40395.aspx A Display Name uniquely identifies a DirectShow filter (or any filter). Display names for software filters have the following format: @device:sw:GUID\\GUID, example: Microsoft’s “MPEG-2 Splitter” display name is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\\{3AE86B20-7BE8-11D1-ABE6-00A0C905F375}. A Friendly Name is not unique and one or more filters can have the same name. However, it is ideal for presenting a descriptive name in user interfaces. For example, the Friendly Name for Microsoft’s MPEG-2 Splitter is "MPEG-2 Splitter"
