If you know DirectX programming, I could use your help, or simply need to pick your brain. Specifically, I'm looking at the DirectInput functions for reading joysticks. I need to sample the joystick <B>way</b> faster than the normal 30 or 60 times a second. More like 120 times a second.

I don't mean to question your design decisions, but I'm curious where this is going. Are you planning on using DirectX functions to implement USB-attached card reader support?
I like Stripe Snoop for a variety of reasons. One of these is that's it works under Windows and Linux. This post seems to indicate that some functions will be OS-dependent. Is that what's happening or am I reading this wrong?
Thanks for your help.

Seeing as how my many system is a Linux system, I want Stripe Snoop to remain as OS-Independent as possible.
The first step to a USB based reader is to stop directly reading from a specific I/O port, because you cannot access USB device this way. To access USB devices, you need to use the functions provided by the OS. I was examining the functions windows uses, specifically the functions windows uses to access Joysticks. These functions are part of DirectX. I tried to use these functions, but found they were too slow. I was looking for people with experience with DirectX or game programming in general, who have done fast access of joysticks, to help me out.

Hmmm. I'll take a look at that. Any special/outstanding webpages/books/tutorials on SDL programming you would recommend? I have some X programming chapters in a few books, but its mainly how to create windows and simple apps in GTK+ and QT.

hey, why dont you use SDL? i love it!! and to all you have to do is include the DLL files that you get with it for it to run on Windows.

yeah, i have this excellent book called Focus on SDL by Ernest Pazera. here is an amazon link http://www.amazon.com/exec/obidos/tg/detail/-/1592000304/qid=1105945848/sr=8-1/ref=pd_csp_1/102-4683368-6421739?v=glance&s=books&n=507846 but i bought mine off ebay for 99 cents. there are some for that cheap right now, i've just checked. Other than SDL, I know Qt would be another alternative. I have some SDL and Qt expierence if you ever need help.
