    Smile Application A interacting with application B

    Hi,

    Yesterday I started creating an application that would interact with an psx emulator and then send key combinations to it when the user presses key X, like a shortcut...

    I did it today.. well, sort of... I created a hook to the target application, and then wrote a function in a dll that should listen to windows messages sent to the emulator, filter it, compare it to key X, and if true, send a key combination to the target application, or else let the key pass unchanged. Some kind of code injection I believe...

    It kinda works to a certain extend... As you probably guessed this increased the amont of processing windows has to do for each message, making the target application horribly slow and almost making everything useless...

    I thought about creating an application that would just send keys to the top window, but this way I would not be able to send the key combination only when the user presses key X... I also thought of hooking the application to the target, send the key combination without waiting for any messages and then unhook it, kind of a "send combination to window X" button.

    I dont know, at least until now, of any other way to do it... I need someway of doing it faster and better...

    Im just asking for directions... It may be something simple, but this is the first time I doing it. What technique should I use? Have you ever done something similar before? If so, what is the best approach? There must be some technique used in order to accomplish this kind of thing...

    Thanks.
