MouseTrap.au3

[somdcomputerguy]

This script uses the _MouseTrap UDF to keep the mouse within a pre-defined box area. I originally wrote it to keep my girlfriends grandkid from clicking 'outside the box' in whatever browser game he was playing. Then she found it useful, and I thought others might too, so here it is. There is one occasional bug/minor nuisance that I have found, that is when it's 'remembering' it's position and size, it sometimes gets the size wrong, and uses the apps size instead of the GUI size. I'm sure there are more 'bugs' in the code, but for the most part it usually works correctly.. Using it is fairly easy, position and/or resize the GUI (arrow keys, CTRL+SHFT arrow keys), start it (F10), ESC quits. I hope others find this useful.

It should be obvious by looking at the code, but I'll say it anyway, if one chooses to run this script, it does write to disk when 'remembering'.

I've updated the code. I don't know if anybody is actually using this, but it does run better (As in the 'minor bug/annoyance' was another 'goof by me'). I've gotten rid of all the hotkeys, and I've also found that reading the help file enables an AutoIt created GUI to be resized with a mouse, and controls to keep a position in that GUI when being resized..
