How to create txt file and append text to existing txt file?

[maxtertj]

At the top of both of those pages, there’s a toggle control which can be used to change the page code to VB or to C#

Thank you, I was able to change it on the VB version code.
I don't know how to try the code there.

I copy and paste it to my form.

I run the form without anything there, hehe I think I did it wrong because it's not working.

Can you help me?
