Javier, Since noone else responded, I give you my one cent worth. Yes you can program Win CE, it uses a subset of the WIn32 API. That's almost the extent of my knowledge . I do believe you'll have to buy a tool specifically designed for Win CE. Microsoft makes an add on for both VB and Vc++ for WinCE. Also I noticed that MobilePlanet ( www.mobileplanet.com ) sells a few development tools for WinCE. As far as, can you program the IR port, my only suggestion is to check MS's site and see if you can find an overview of the CE API. You might find the answer you need. Good luck.
