I just started this blog. I will import the existing stuff from hjgode.de/dev  from time to time. But now, here is my first post.
Microsoft decided to discontinue GAPI. That is OK for me, as I only use GXOpenInput and GXCloseInput to disable the hijacking of function keys and to have a kiosk application that dies the user not reach the OS.
I discovered this at community.intermec.com. There is a message linking to http://blogs.msdn.com/windowsmobile/archive/2009/05/06/just-say-no-to-gapi-what-you-need-to-know-about-allkeys-and-input-management.aspx .
I will test the function of BOOL AllKeys(BOOL bEnable) and if it works like GXOpenInput() I hace no concerns about using it instead.
