c# - Prompt the user to download an excel file built server side -


I have a way of calling my CreateAnnuityExcel sheet when pressed on the "Create button".

Public ActionResult ShowAnnuityPMT (FormCollection is the form, string SubmitValue, name of the string file) {// to finalList, the code (SubmitValue = = "Save") {CreateAnnuityExcelSheet (finalList: Method To CreateAnnuityExcelSheet Call, Form, DTCIer); // When I call this method, I want to download the excel file created in the user / browser CreateAnnuityExcelSheet} Return the partial view ("ShowDetail", the last list); }

The method looks like this: 

  Public Zero CreateAnnuityExcelSheet (list of calculation> cList, formCollection as intDTCyear) {list From & lt; Count & gt; NewList = New list & lt; Count & gt; (); NewList.Add (cList.First ()); // Get value for the first line StartValue = newList [0] .StartValue; Var Radio = Form ["Advance Orories"]; String filename = newest list [0] .CalculationName; String path = @ "c: \ excel file \" + filename + ".xlsx"; // file file information information for file = new file info (path); Info.directory.Create (); // So C: (! Info.Exists) \ ExcelFiles does not exist if it's created by using {ExcelPackage package = new ExcelPackage (info)} {ExcelWorksheet ws = package.Workbook.Worksheets.Add (file name) ; // Styles for Sheet Stream = new memorystream (); package.SaveAs (stream); section. Composition = 0; Byte [] bytes = stream Getbuffer (); reaction. Buffer = true; Response.Clear (); Response.ContentType = "app / xlsx"; Response.AddHeader ("content-type", "attachment; file name = report.xlsx"); Response.BinaryWrite (byte); Response.Flush (); }   
 The main problem is that I am creating an Excelsheet on the server side and then want to send it back in the browser to download it. How can I send my package back to the browser to download?  
 The method is returning zero now, should I return the file? But if I do, then how do I send the file with a view, so that the user can begin downloading the Excel file?  
 This shows my view: This displays my view  < / Div> 
 
 
 Your action should return an ActionResult and if you have a stream, then an easy way  
 There is no asset to set the name of the notice file to use.  
  New filestream result (stream, "app / vnd.ms-excel") {FileDownloadName = "myfile.xslx"};   
 Here's a sample to post data to your form and download the generated file.  
 Create a model to keep form values:  
  public class DownloadModel {public int InputA {get; Set; } Public String InputB {get; Set; }}   
 Create a controller with two actions: one to display a form (index) and another to submit the data and to get the file (downloadfile)  
  public class DownloadController: controller {public performance index () {return view (); } Public Performance DownloadFile (DownloadModel Models) {// Read Form Price Through Module System. Diagnostics Debug.WriteLine (model.InputA); System.Diagnostics.Debug.WriteLine (model.InputB); // Assume that we create an Excel stream ... MemoryStream excelStream = new MemoryStream (); New FileStream Receipt Return (excelsstream, "app / vnd.ms-excel") {FileDownloadName = "myfile.xslx"}; }}   
 Razor Scene Download Action Form / Index.cshtml for DownloadFile Action in Set  
  @model WebApp.Models.DownloadModel @ {ViewBag Titles = "Download file"; } & Lt; H2 & gt; Download file & lt; / H2 & gt; @Usage (Html.BeginForm ("DownloadFile", "Downloads")) {@ Html.TextBoxFor (model = & gt; model.InputA); @ Html.TextBoxFor (model = & gt; model.InputB); & Lt; Input type = "submit" value = "save" name = "submit button" /> }

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...
