c# - Changing the BackColor of a Windows Form -


Why can not I change the backcolor of my form in this form? 

  MainForm BackColor = System.Drawing.Color.Black;   
 In this console I get:  
  requires an object reference to non-static field, method, or property 'System.Windows. forms.Control.BackColor.get '(CS0120)    
 
 
 are classes that are not Instantiated Static classes are static methods or static properties (or both) when you use a line like this:  
  The mainform. Backside = System Drawing Collar Black; // & lt; Class name & gt; & Lt; Property & gt;   
 What the first C # compiler does is for the local class variable called 
 MainForm . Since there was no one, it was seen outside of your local area and got its own code named "Windows.Form  class  MainForm .  
 Then it was seen to see that there is a fixed asset in class  MainForm  which is called  BackColor . Compiler said, "Oh look,  BackColor is a property called , but its not static ", which is when the compiler complains to you and threw you the error.  
 To change this,  this.BackColor , the compiler knew that you wanted to set the background color of this direction of the mainform, which is  this  Or, by default,  form1 :  
  this.BackColor = System.Drawing.Color.Black; // & lt; This example & gt; & Lt; Property & gt;   
 And as a side note, the keyword  this  is not required except "This object" is assumed that you can do the same:  
  backallore = system. Drawing Collar Black; // & lt; This example & gt; & Lt; Property & gt;   
 Hope that makes more sense!

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...
