How is polygon described?

How do i draw a polygon using visual basic? I need the code to let users draw a polygon?

• i need the code for drawing a polygon once someone clicks on the draw polygon button, also the code for calculating area of this polygon as well as calculating if a point is located in a polygon, the x, y co-ordinates of vertices as well as calculating the co-ordinates of a line that intersects with this polygon using visual basic

• Answer:

  write code in the form_mousedown event. This will give you the x and y coordinates where they clicked on the form. Then, use the Form.Line method to draw a line, between the two points where they last clicked. Doing this, the user can draw the lines of the polygon one-by-one.
