Passing though a function

  Hi Rykon
  
  They called Methods Rykon.
  
  I am not sure how you mean make a function?
  Can you tell me what it is you need to do?
  You need a basic structure of a method and how to call it?

  My question is for this type of example in C++
  
  Int myfunction(int hi)
  {
  int j;
  j = hi + 2;
  
  Return hi;
  }
  then calling it
  int h = 4;
  myfunction(h)
  
  I can not get the "myfunction(h)" to pass into "myfunction9int (hi)"

  keke, in the example you provided, you return the same variable you've put as parameter, unmodifyed.
  Anyway I've, a little bit, forgotten c++, try calling myfunction from other function. Is myfunction in the global(is global function) namespace?
  
  Furthermore, you should try addressing your question in the C++ Forum ;-)

  First I was doing a compare to c++ and the code was psuedo. You where no help to my question, read the first post.

  Sorry, thought, I didn't see the comparement.

  That is ok, I was giving an example in c++ and I was wonder the C# equiv. Might I add I need it to work with a static and an object.

  I'll try to give an example of what I think you are trying to express (hopefully, if we are both lucky, i will not be wrong )
  using System;
  namespace MyTestSpace
  // namespace
  {
  // simple SHOWOFF class
  public class WhatACalculator
  // class
  {
  // simple static method
  public static int Add(int fNum,int lNum)
  // method
  {
  // add the two values and return the result;
  return fNum+lNum;
  } // end method
  static void Main()
  { // method
  int myAge=18; // yes i'm 18
  int myGirlFriendsAge=16; // no, my girlfriend's is not 16
  int myMomsAge= // because my mom's age is 35 ;-)
  // calling the static add method, we don't need an object instance forIt
  WhatACalculator.Add(myAge,myGirlFriendsAge);
  // display the result from the Add method usage;
  Console.WriteLine(myMomsAge.ToString());
  } // end method
  } // end class
  } // end namespace

  There is one problem with this code, it is not that same (to my knowlege) as one needed for a Windows app, not a console app. The main diff that I can find is the passing through an object(i.e. no static). Could you be any help on that?

  :
  First - yes this is console demo app.
  Second what help exactly do you need, i'm confused now

  Ok, I can make a console app and get methods to work, but when I try the same tactic on a windows app it will not work. The only difference that I can see it that I am trying to pass from a object(i.e. a method for a button) to a static method. Any idea of what I am talking about now?

  : How can I make a new function and pass a var. through it?
  :
  Ok.
  
  Look every thing is a class right and when you instantiate a class it becomes an object.
  When you make a method static you use the class name and the dot notation to indicate witch static method to use like so:
  
  public class MyClass
  {
  static string MakeComent()
  {
  return Hi;
  }
  }
  
  public class MyDriver
  {
  public MyDriver()
  {
  
  }
  
  public static void Main(string[] args)
  {
  Console.Out(MyClass.MakeComment());
  }
  }
  
  PS. I am using a console app for now.

  Now when you make the class an object things change.
  Your first class needs a constructor first of all.
  
  public class MyClass
  {
  public MyClass()
  {
  }
  
  public string MakeComent()
  {
  return Hi;
  }
  }
  
  The Driver class Main Instantiates the Class and Calls the method through the Object:
  
  public static void Main(string[] args)
  {
  MyClass myNewObject = new MyClass();
  Console.Out(myNewObject.MakeComment());
  }

  Now when you use a Windows app, one has to be careful not to get mixed up between the driver and your class. The code window presented to you at start-up is the driver and I suggest you add your custom class to the project You should follow the same approach in the console app by the way
  
  You will then have a choice between using a global instance and a local instance in the event handler methods.
  
  In the former you would instantiate the object in the Main method while you would need a global reference together with the other form object references
  
  Using MyClass;
  public class form1
  {
  private System.ComponentModel.Container components = null;
  private MyClass myNewObject = null;
  
  public static void Main()
  {
  myNewObject = new MyClass();
  }
  }
  
  In the Later one would just instantiate a local instance inside the EventHandler method:
  
  private void button1_Click(object sender, System.EventArgs e)
  {
  MyClass myNewObject = new MyClass();
  MessageBox.show(MyNewObject.MakeComment());
  }

  When you want to pass parameters:
  
  private string MyMethod(int times)
  {
  return Its the + times.ToString() + th Time;
  }
  
  public static void Main()
  {
  for(int I; I < 9; I++)
  {
  Console.Out(MyNewObject.MyMethod(I));
  }
  }
  
  PS non of my code has been tested, but you will be able to see what to do.
  Ask if you still dont understand.
