I am creating a Map Rotation Randomizer for my Call of Duty clan, and I am having an issue with understanding how to randomize the text from the list and placing it into another textbox.

Here's what it looks like right now:



All textboxes are multi-line.

When I click a button for a game (CoD4, MW2, WaW), it places the map list into the left textbox like:

mp_bloc
mp_broadcast
mp_crossfire
etc.

When I click the button with ">>>", I want it to randomize that list and place it into the right textbox like:

map mp_bloc map mp_broadcast map mp_crossfire

or if I click it again:

map mp_crossfire map mp_bloc map mp_broadcast

and so on. I think I need to create an array, but I've never worked with those before as I'm still new to learning programming. I'm not even sure what controls I need to put on the form for that, if it even requires any.

If you need the code list or something let me know. Thank you in advance.
