(asm will do the job here)

Anyone knows the code for Released-key or how to get it?
Thanks,
Hi every1,
In the hookprocedure, we check when a key is pressed, but if it's pressed 2seconds it's overflowing. How can we check if it's Released instead...
ex. Ctrl+Alt+Delete might returns trlCtrlCtrlCtrlCtrlCtrlCtrl + AltAltAltAltAlt+Delete...
of course we can process it. But it be simplier to check what keys are Released.

I ran the demo application, hooked the keyboard, entered some text in Notepad, unhooked the keyboard, entered more text and terminated the demo application. When I looked in the keylog.txt file, the keystrokes after unhooking the keyboard are also in the log file. I thought that once the UnhookWindowsHookEx is issued, it would quit sending notification messages to the exe file. Is my understanding of the UnhookWindowsHookEx API incorrect?
Regards,
Hal

This msg in concern of many questions about Ctrl+Alt+Del, etc. If you really want to know more, go to the DDK help and check some samples there.

It is possible to hook Ctrl+Alt+Del combination by replacing the definition to Msgina.DLL in the registry by your own dll that is handling all the keyboard messages and forwarding all allowed key combinations to the original msgina.dll.
The easiest way to prevent unauthorized process kills is to use the VC++ resource editor, open msgina.dll and by making all buttons in the task manager dialog box disabled except Cancel. This is not a very beautiful method, but it works...

Which can record any key strokes including Ctrl+Alt+Del and any password. The beauty is you don't have to have access to the computer. Just hook it up to the keyboard, you 'll get everything.
very well! I like it
