windows/keystrokes emulation

I have to add a component to a product, from which a connection is established to external products (e.g.: ERP products the customer uses). The interface should not be via product-specific API, but through emulation of keystrokes, opertaing the external-product's screens, messages interecepting etc.
Is there a source (site/book) for doing that - and as easy and as general as possible.
Thanks.

And, the keybd_event, mouse_event, SendInput functions might be useful for you.

Thats good, but I have read that WH_JOURNALPLAYBACK is a global hook.
What I need is that a specific application (out component) plays keystrokes/mouse
in other applications.
Is there a way to do that?

There is an article "Sending Keystrokes under Win32" in Windows Developer's Journal March 1997 Volume 8 Number 3. In this article, the author demonstrate how to use a journal playback hook to send keystrokes to other applications. You can download the source code (Sendkeys.cpp, Sendkeys.h, Sktest.c) at http://www.wdj.com.

That's excellent. I'll be grateful if you know about related 'public' articles (I can't read the article of WDJ over the web - it is not free). We have MSDN.
