Hook function sequence and hook into the order of the hook chain, on the other hand, after the hook chain hook function to deal with first. So, just make sure to install the keyboard hook at the end of the hook chain can always. This implementation can use the following way:

Whenever password box gains focus, install the keyboard hook, when focus away to remove it. So when the password in the password box can guarantee the hook function processing first, and will continue to deliver or send this message not simulated keyboard message.

Keyboard hook to ordinary hooks, so other programs if installed the lower hook, it is possible to the keyboard hook to deal with it before processing. This also can adopt the same way, make oneself of the low-level hook at the end of the hook chain.
