Reset Method (IPFilters)

Summary
Resets the collection to its default settings.
Syntax
C#
VB
C++
public void Reset() 
Public Sub Reset()  
public: 
void Reset();  
Remarks

Reset is performed on the parameters stored in memory. To change the file settings call the SetIPFilters method.

The default collection contains a single filter that allows connections for the entire IP address range.

If the method fails, an error is raised. For more information, refer to the Error Codes.

Example
C#
VB
using Leadtools; 
using Leadtools.MediaStreaming; 
 
 
public Server _server = null; 
public bool _result = false;
