c# - Refresh page after FileWatcher event -


i have filesystemwatcher in asp net mvc application. detects .txt files when changed. should show these changes on view page. can not understand how does. because how call page refresh filesystemwatcher? or must write settimeout js function on client side? here code:

public class filewatcher {     //private int readlinescount = 0;     private string watchedpath;      public filewatcher(string watchedpath)     {         this.watchedpath = watchedpath;         initfilesystemwatcher();     }      private void initfilesystemwatcher()     {         filesystemwatcher ofilewatcher = new filesystemwatcher();          //set path want monitor.         ofilewatcher.path = watchedpath;          //set filter expression.         ofilewatcher.filter = "*.txt";          ofilewatcher.changed += new filesystemeventhandler(filesystemwatcherupdated);          ofilewatcher.error += watcher_error;          ofilewatcher.enableraisingevents = true;     }      private void watcher_error(object sender, erroreventargs e)     {         // watcher crashed. re-init.         initfilesystemwatcher();     }      void filesystemwatcherupdated(object sender, filesystemeventargs e)     {         //a file has been changed in monitor directory.         try         {             recordentry(e.name);         }         catch (exception)         {             initfilesystemwatcher();         }     }      private void recordentry(string filename)     {         blogic bll = new blogic();         bll.addparamsbyfilewatcher(filename);     } }

and blogic's method:

public void addparamsbyfilewatcher(string filename) {     if (filename != null)     {         homecontroller controller = new homecontroller();         controller.server.transferrequest("/home/monitoring", false);     } }

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
