In your project right click, select Add new item, select to create a new custom or user control. The difference is that user controls are combination of already existing controls (just align them, make them act together, etc.) while the custom control is a control you should make yourself.

The user control inherits from the class UserControl in System.Windows.Forms namespace while the custom control inherits directly from the Control class in the same namespace.

ok, so i want to use the custom control,

i know that i have to use the System.Design , System.Drawing,

basicley i want to design my own rectangle box with the following properties
.ColumnWidth =100
.ColumnHeight =200
.BackColor = SystemColors.Desktop
.BorderColor = Colours.Ivory

then save it as a dll and to be able to use it with another piece of code where i can add it on to the contorl box

You need to make the project a class library then and compile it to a dll. Then you can add the control to the toolbox.

You also need to override the OnPaint method of the Control class. For more info see Control.OnPaint in MSDN

I think you should call base.OnPaint before your own drawing (although I am not sure)

Why do you think you miss something?
