MS VS 2005 - sample project

[mikeda]

hello...

i've got a big problem concerning the sample projects... i downloaded both of them and could compile them without any problems...

but when i tried to make a new console project based on those sample projects they simply don't do what I like them to do... (printing numbers which represent forces and momentums applied to the cap on the screen...)

I could compile them and where I'm printing the devicetype it's 6 (for spacenavigator) so the connection to the device should actually be established... but why do all the other values remain 0 even if i move the cap... ???

I'm asking kindly if anybody could explain me what I'm doing wrong... ?

Has anybody got a very basic hello world project which could be shared somehow ?
