(adsbygoogle = window.adsbygoogle || []).push({}); Me and my friend are making a program and I was wondering if someone could tell us the code so when you click on a button in the menustrip you get code in the richtextbox?

add a menustrip and then add a menu say File
then add your sub item called say Insert Text.
then double click the item until you go into the code viewer and away from the designer
finally insert the code
richtextbox1.text = "Your Text Here"
