Using objects with secondary forms... Whats wrong here...

Hello...

I am trying to create a pop up save box for a program of mine...

Basically, I am calling a new form from the main form I have so:

public partial class Form1 : Form
    {


        public Form1()
        {
            InitializeComponent();
        }

Is the standard form I'm using that visual studio automatically creates. Now when you click a button(button1 in this case), I want to call a new form(form2), here is the code:

private void SaveVariable_Click(object sender, EventArgs e)
        {


            form2 saveform = new form2();
            saveform.Show();
            saveform.Visible = true;


        }
    }

// below is a new class

    public class form2 : Form
    {




            //constructor
            public form2()
            {
            //initialize components
               Label label2 = new System.Windows.Forms.Label();
                label2.AutoSize = true; // this.label2.AutoSize = true;
                label2.Location = new System.Drawing.Point(55, 55);
                label2.Name = "label2";
                label2.Size = new System.Drawing.Size(39, 13);
                label2.TabIndex = 10;
                label2.Text = "Label2";
                label2.Visible = true;
            }

    }

However, when the program runs, while the new form object is created, no label box appears anywhere. What am I missing? I've tried using   this.label2.X as well for all of the form2 variables but it doesn't change anything....

Sir,

I have never created controls on the fly.

so dont know much about that but if you see when you place

controls on the form a container is initialised in the YourForm.Desiner.cs

and then there is InitializeComponents Which New`s That all you have placed on the

form.

so what you are missing can be seen on the designer class of your form by placing some controls on it

Secondly if you are making a save box of which you know how and what should work on it

then make a form allready and place all the controls on it that will save you lot of coding

also.

In my infant Way of programming which is my hobby. i take this approach

create all the forms place controls on them

now make a ControlCenter.cs class

declare all the forms and classes in that like this

//forms

public static YourProgrammName.YourForm1 YourForm1_variable ;
public static YourProgrammName.YourForm2 YourForm2_variable ;

public static YourProgrammName.YourForm3 YourForm3_variable ;

//classes

public static DealWithSomething InSomething = new DealWithSomething () ;
public static DealWithSomething2 InSomething2 = new DealWithSomething2 () ;

//In Programm File which every cs programm has Programm.cs

//after these statements

Application.EnableVisualStyles() ;
Application.SetCompatibleTextRenderingDefault( false ) ;

// initialize the form variables
ControlCenter.YourForm1_variable = new YourForm1 ;

ControlCenter.YourForm2_variable = new YourForm2 ;

etc etc..

// now the form that you want to be the main form

do like this

Application.Run( ControlCenter.YourForm1_variable ) ;

//that`s it

You can call these variables anywhere in your programm and they will

show you all the controls in the forms you have put while making them

and Rest all the programming is the same as always

Lastly if you have to work with the controls of one form in another

you have to make their scope/modifier public

ThankYou
