c# - Read textbox and assign input to variable in another class -


I have tried to go through similar questions and answers about this subject, but I have a solution Or to understand).

On Form 1, I have three text boxes that will get user input. In a different class I have a way of using input from those text boxes.

Form1.cs only have text boxes and some buttons. The method in the other class is using 

  system; Using System.Collections.Generic; Using System.Linq; System usage threading. Task; Using System.Windows.Forms; Name Location RealEstateApp {Public Class RealEstateApp: Form 1 {/// & lt; Summary & gt; Main entry point for the application /// & lt; / Summary & gt; [STAThread] Public static zero Main () {Application.EnableVisualStyles (); Application.SetCompatibleTextRenderingDefault (wrong); Application.Run (New Form 1 ()); Const. Double RENTAL_AMOUNT = 1000.00; Real Estate Investing Investment 1 = New Real Estate Investment (2004, 150000, "65th Street"); Invest1.MonthlyExpense = GetExpenses (); invest1.IncomeFromRent = RENTAL_AMOUNT; invest1.DetermineMonthlyEarnings ()); Real Estate Investment Investments 2 = New Real Estate Investing ("72 Westchester Dr", 22, 9, 000); Invest2.MonthlyExpense = 900; Invest2.IncomeFromRent = 1500.00; } Public Double GetExpenses () {Double Insurance; Double taxes; Double utilities; String in value; InValue = txtBoxInsurance.Text; //Console.ReadLine (); (Get user input from textbox) insurance = double. Purse (inverted); InValue = txtBoxTax.Text; //Console.ReadLine (); (Get user input from textbox) = double. Purse (inverted); InValue = txtBoxUtilities.Text; //Console.ReadLine (); (Get user input from textbox) utilities = double. Purse (inverted); Return (insurance / 12 + tax / 12+ utilities); }}}   
 As I have seen before you C # people, I have met an error 'an object reference non-static field, method, or  
  Edit   
 I have static zero main () in the second class if it changes anything.  
  
 mat   
 
 
 I think you are getting the error on  inValue = txtBoxInsurance.Text   
 The reason for this is that your  GetExpenses ()  method in the static class is. When  txtboxInsurance  is the private and non-static property of the class  Form1 . You can not access static methods from non-static method properties.  
 What you can do instead  
  Public Static Class YourStaticClass Static String _ Insurance; Static String _tx; Stable string _ qualification; Public stable double GetExpenses ()   
 
  {double insurance; Double taxes; Double utilities; String in value; // console Write (Annual Insurance: "); InValue = _insurance; //Console.ReadLine (); (Get User Input From Textbox) Insurance = Double Purs (InValue); // Console. (Yearly Tax:"); InValue = _tax; //Console.ReadLine (); (Get user input from textbox) = double. Purse (inverted); // console Write (Monthly Utilities: "); InValue = _utilities; //Console.ReadLine (); (Get User Input From Textbox) Utilities = Double Purs (InValue); Return (Insurance / 12 + Taxes / 12+ Utilities); }    
 and  
  public partial section Form 1: Form YourStaticClass._insurance = txtBoxInsurance.Text; YourStaticClass._tax = txtBoxTax.Text; YourStaticClass._utilities = txtBoxUtilities.Text;   
 I think this should work

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...
