Leadtools.Multimedia Namespace > FilterEnum Class : SetEnable Method



Name
string to the Display Name or Friendly Name of the filter. It is always preferred to use "Display Name" since it is unique and no two filters can have the same Display Name. On the contrary, two filters or more might have the same Friendly Name. In this case this function will work on the first filter it internally enumerate with the specified friendly name.
Value
True to enable the filter, false to disable it. This only work if the filter origional merit is 0x200000 (MERIT_DO_NOT_USE). Setting this value to false will set the merit to 0x200000 (MERIT_DO_NOT_USE). Setting this value to true will bring back the orgional merit value.

Remarks

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 there might be one or more filters with 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"
