Do you mean objects overall, or only controls like these in Windows Forms?
As you know, object is an instance of class. So you need to understand how
to
define classes (not objects) etc..
Read about constructors, methods, fields, operators, properties -> object
oriented programming.
Threre is a lot stuff in Internet, try google.

But if you mean objects as controls like WinForms, try examples in CodeGuru,
http://www.codeproject.com/
or google.

If I am following you correctly, you are asking how to create custom
controls based off of form objects. If that is the case then here is
how I usually start off:


using System;
using System.Windows.Forms;

namespace CustomControls
{

public class CustomButton : System.Windows.Forms.Button
{
public CustomButton() {}
// Add any other functionality you want in here.
}
}

The only "problem" doing it this way is that you cannot use the visual
design view to make changes, it is all code based. When you compile and
add it to a form it will appear correctly.

If you want to be able to view your control in designer mode:

namespace CustomControls
{

public class CustomButton : System.Windows.Forms.UserControl
{
private System.Windows.Forms.Button button1;
public CustomButton()
{
button1 = new Button();
}
// Add any other functionality you want in here.
}
}
