Keyboard hooking problem

Hi everyone,

I am making a key logger using the set Windows key hook. I have been stuck in a weird problem with the hooks.

My code is working fine when I try typing in notepad or any thing like that, but whenever I type something on the Internet i.e. in the address bar or chatting every character is repeated twice.

I have debugged the code and get to know that Windows key hook is sending the message twice in case I am typing on the Internet browsers.

So why is it sending the message twice in case of the Internet? Does anybody have any clue regarding this?

It would be very helpful for me.

As I never faced with such thing, and a Web browser is nothing but a regular application, no different from any other, its hard to say anything without seeing you code. Could you make a simplest possible code sample, minimalistic, just to demonstrate the problem?

By the way, does it happen in all browsers or just one; which one? Please check up.

Solution 1

Check if the code parameter in the keyboard hook procedure is HC_ACTION.
Do the processing only if code is HC_ACTION.
