I just wrote this because I said I would here.

CTRL + ALT + h = Hide/unhide the active window.
CTRL + ALT + q = Kill ToggleHide, if there is a window hidden it will be shown.

The code is not commented, because it's fairly straight-forward.
It's released under the GPL, because I don't see anyone use this in any personal project. So just share if you modify/extend.

Very Nice

, havn't tested because I'm unfamiliar with the programming language (I'm unfamiliar with anything non-vb oriented

, and please don't make an issue about that..), not as functional as Cloak.. but thats because its not a full program

(if you did make a full program I'm sure it would beat Cloak into the ground

), I don't have the option to hide the active window though... and that seems like a VERY good idea, I'm gonna put that in the next version. Great job again

What other features does Cloak have?

You don't? Which window does it hide then?

Thanks for the feedback.

brownhead · May 9th, 2006, 12:05 AM

Cloak can set the translucency of a window (not hard, just another API... Cloak is a simple project, theres no denying that, it really wasn't that hard to make), the title (SetWindowText API), and a bit more advanced hotkeys..
You target windows by selecting them, not by pushing a button and whatever window you have focused on will dissappear.
G'day to ya

Minor correction + some defines to reduce size to 2.5 KB and only one instance of the program at a time.

Great job again

Cloak is a simple project, theres no denying that, it really wasn't that hard to make), the title (SetWindowText API), and a bit more advanced hotkeys.. You target windows by selecting them, not by pushing a button and whatever window you have focused on will dissappear. G'day to ya
