PocketHAL / MFC example?

[clintsinger]

I have a full screen application (windowed on the desktop) that is required to be done in MFC. Does anyone have an example of how to override the default drawing capabilities of MFC and replace them with a PocketHAL implementation?

Cheers,
Clint

Why do you want to use MFC for a fullscreen app? That will only add overhead to your app.

Hi Thierry,

I made an attempt to try PocketHAL with MFC and ran into a linking problem. It seems that PocketHAL has linked to a couple libraries that MFC is trying to link to as well and this is causing a conflict. The errors are as follows:

The application I am writing has the UI portion borrowed from the fireworks sample so that there is no requirement on MFC to do the drawing, event processing etc, but I still need MFC because the rest of the application uses it extensively.

Is there some way to get a pockethal library that compiles nicely with MFC?

Hi Thierry,

I thought I'd mention that I am using PocketHAL .8 Alpha 3 on Windows XP for the MFC test. If that helps at all. The goal is the ability to compile the same application for the desktop and windows ce.
