Raw data access

Hi,

I am trying to access the SpaceNavigator in a command line application.
As advised in other posts, I went the 'HID' / raw data way.

I am using the system API: GetRawInputData + WM_INPUT message.

Ok, so now I get a set of bytes that change when the device status changes. How do I interpret those ?

Or am I making it too hard and is there a simpler way to get the device axis and button state ?

Thanks

Julien Berta.

Hello jberta,

I'll have a look at this and get back to you shortly.

Hi Julien,

If you want to try another method, I've posted a HID example in this post

I will still look at WM_INPUT.

I've created an example of how to use WM_INPUT (RawInput). It is on the same ftp site. It takes about the same amount of code, but does handle disconnection and reconnection of new devices quite transparently.

All the same caveats about bypassing the 3DxWare driver...
