Re: REQUEST: webcast or tutorial on Gapi with .net

For P/Invoke example take a look at
http://www.alexfeinman.com/download...oc=GAPITest.zip

I don't remember if the 4 keys can be intercepted via GAPI, but it's either
that or RegisterWindowKey.

I'm x-posting this to dotnet.framework group, as this conversation
obviouslly belongs there rather than here

I've got an article coming out on Intel.com on GAPI and .NET CF. One's an
intro and one's an optimized batched EVC++
DLL for Compact Framework Apps...

Sorry... Posted too quickly. I'll post the URLs to the embedded gaming
articles to be published on Intel's IDS/IDF sites as soon as I know the
URLs.

I'll post what I have in terms of projects to show how well a game can run
