public:
void SetEnable( 
   String^ Name,
   bool Value

Parameters

Name: A string that represents 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.
Value: true to enable the filter, false to disable it. This only works if the filter's original merit is 0x200000 (MERIT_DO_NOT_USE). Setting this value to false will set the merit to 0x200000 (MERIT_DO_NOT_USE). Setting the SetEnable value to true restores the original merit value to the filter.

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 a 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"
