Using + And - Keys To Increment Textboxes?
Jun 11, 2009I have about 20 text boxes that I would be able to change via the + and - keys... So when I hit the + key it goes up, and the - subtracts one. How would I go about doing that?

Recored Arrow Keys And Then Tell Computer To Enter Arrow Keys?
May 23, 2010So I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.

Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.
