c# - passing input text from view to contoller with FacebookContext using Facebook app -


I'm trying to pass an input text from the viewer to the controller in the Facebook Birthday app: Link to app:

In the Home Controller 

  [FacebookAuthorize ("email", "user_photos")] Public async Tasks & lt; ActionResult & gt; Index (FacebookContext reference) {if (ModelState.IsValid) {var user = waiting for reference. Client.Gate CurrentUserAsync & lt; MyAppUser & gt; (); View return (user); } See Return ("Error"); } [Http post] [facebook authorized ("email", "user_photo")) public async task & lieutenant; Actionsclass & gt; Index (string textile, facebookcontonte context) {if (ModelState.IsValid) {var user = wait context.Client.GetCurrentUserAsync & lt; MyAppUser & gt; (); // See my code, see the use of txt here (user); } See Return ("Error"); }   
 View:  
  @using facebookpostc.models @ Microsoft.AspNet.Mvc.Facebook.models using @ Microsoft.AspNet.Mvc. Facebook @model MyAppUser @ {ViewBag.Title = "Home Page"; } & Lt; Article id = "content" & gt; & Lt; Div class = "right" & gt; @Using (HTML.benform ("index", "home controller")) {& lt; Br / & gt; & Lt; Span & gt; Please input your text: & lt; / Span & gt; & Lt; Input type = "text" id = "txt" name = "txt" /> & Lt; Input type = "submit" / & gt; } & Lt; / Div & gt; & Lt; / Article & gt;   
 But this text is not passing, I tried to pass the text in many ways but none of them got the text.   
 
 
 You can read it from  FormCollection :  
  [http post] [facebook rights ("email", "user_photo")] public async work & lt; ActionResult & gt; Index (form collection form, facebook contact reference) {if (ModelState.IsValid) {string temp = form ["txt"]. ToString (); Var user = wait for reference. Client.GetCounter User Async & lt; MyAppUser & gt; (); // See my code, see the use of txt here (user); } See Return ("Error"); }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
