String help

[Craig]

Hi all,

I need help with the indexof function, basically what I need it to do is when I find the first indexof, loop through until all instances of that char/string

Ex:

Say a user inputs:
- "Hello, my name is craig" into textbox1
- "a" into textbox2

I need the program to add each index of textbox2 ("a") from textbox1 into a listbox (it should return 11 and 20)

Thanks
