Currency value into words

Question

Hi all. i am working on a reciept generating form, So when i enter the amount recieved for example " 30,000 "  into my " textbox1.text " i would also like to convert the value in textbox1 into words that is in my " textbox2.text " will show " Thirty Thousand Shillings only " 

Is there any code that can convert my currency value into its words equivalent.

Thanks for reading my inquiry.
