c# - Function associated wth a property does not fire? -


enter code herei have propert in .cs file. when ever set property event associated gets fired.

    public event action responsereceived;     private string response;      public string response     {                  {             return response;         }          set         {                 response = value;                 if (responsereceived != null) { responsereceived(); }         }      }

now problem in file when do

responsereceived += new action(function_responsereceived); void function_responsereceived() {     //change gui thread     if (invokerequired)      {            this.begininvoke(new action(function_responsereceived), new object[] { });          return;      }      textbox1.text = response; }   response = "yes";

. . . (after lines) . . .

response = "no";

but yes not fire funcion associated event response = "no"; fires (the response field updated faster time takes fire event over-written, guess) . there way both times when set property function asscoiated event fires properly

initial answer:

the code show works fine.
there must in code mentioned '. . . (after lines) . . .'.

testcode:

using system; using system.collections.generic; using system.linq; using system.text;      namespace functionassociatedpropertyfire {     class program {         static void main(string[] args) {             new testclass().test();             console.readline();         }     }     class testclass {         public event action responsereceived;         private string response;             public string response {             { return response; }                 set {                 response = value;                 if (responsereceived != null) { responsereceived(); }             }         }          void function_responsereceived() {             console.writeline("function_responsereceived");         }          public void test() {             responsereceived += new action(function_responsereceived);             console.writeline("beforeyes");             response = "yes";             console.writeline("afteryes");             response = "no";             console.writeline("afterno");         }     } }

testresult:

beforeyes function_responsereceived afteryes function_responsereceived afterno

update:

you invoking asynchronously, invoking code doesn't wait invoked method finish. can try use invoke-method instead of begininvoke-method.

void function_responsereceived() {     //change gui thread     if (invokerequired)      {            this.invoke(new action(function_responsereceived), new object[] { });          return;      }      textbox1.text = response; }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
