ok I have an outlook form. ( the first time I've ever tryed making one)

On the compose page I have a textbox1 which the use is to fill out.

Then upon hitting send I want value of of textbox1 to become the subject line of the read page.

something like this but in Outlook code.
Subject.text = textbox1.text



I know nothing about outlook code is there a good place to find complete code for beginners.
