C#/.NET Macro Recording and Playback

I'm in charge of taking an Excel VBA app and turning it into a stand alone piece of softwar开发者_高级运维e. The main point of the functionality is to be able to record macros and play them back, think Website testing, mass SAP entries, anything a macro would be good for. I am not looking to re-invent the wheel, but I won't have the ability to install 3rd party macro recorders either. Which libraries or toolkits would you recommend I look at before getting started? Someone has recommended AutoHotkey to me, but as far as I can tell, it is standalone and doesn't exactly work inside of an application.

I found a sample Global Mouse and Keyboard library here, that in my initial testing seems to be compatible with at least .NET 3.5 (and probably others). The demo applications show the proper use of tracking events and also contains a demo macro recorder. So far, this is the option that I'm pursuing, but if anyone else knows of better toolkits/libraries let me know!

It's open source, by the way.
