How can I write Barcode Generator?

Question

I would like to make a program that takes input as a string like 'dsfljsfkj' then output 2D Barcode (DataMatrix format, or other 2D formats) as an image file in VB.NET

Do you have any idea how can I make it without using any other commercial .dll's? Open-source is OK.
