Hello, I would like some help with hooking the GetForegroundWindow() function. So that the OS will notify the program when there is a change in windows, without having to poll 60 times a minute and hog the cpu. As far as I know, this is the most efficient way of being notified. I have never done hooks before, so assistance with this is greatly appreciated.
Thanks for the help in advance.
If you've never investigated hooks before, how do you know they're the most efficient option? Setting a hook in a function in every process might not be calling 60 times a second, it might be 0, 50, or 200 on top of the extra memory and performance impact the hook has.
Anyway, why do you want to do this? Your window will get notifications when the user starts and stops interacting with it, that is usually enough for all but the most insidious programs.
I'm making a keylogger that notifies when the user changes windows. I'd make a game but it wouldn't look pretty... :)
So if this isn't the most efficient way, then what way is?
The keylogger isn't meant for anything malicious, just to make for fun.
I'm pretty sure you'll want something more constructive on your CV if you want to get a job later on.
What do you mean more constructive Salem? And if I want a job later on?Quote:

Again, my purpose is to receive the title of the current foreground window when the user changes windows. Of course this is trying to hook it. Are there better ways of receiving this information (as Salem may have suggested)?
Dude, I think you better quit while you aren't banned.
Consider this just a bit of friendly advice; the last person who open claimed "I'm making a keylogger" was quickly removed.
Your claim of intentions aren't all that relevant. We don't know that you don't have malicious intentions.

Ok thanks for the warning. I quit this and there is no need for any reply. I understand where your coming from completely, so that's it then.
