Where do I start?

[Mike Houghton]

I joined this forum because I need help (really). Am trying to interface my C++ app to a USB driver because all I really need it to do is capture a still from from a webcam in my own (C++) domain. Having used WinAPI for VB, it may be easier to do what I want with API in C++ ? If so, what do I need to buy to do it ? Any pointers...?

Welcome to the forum!

Do you have an API reference for the USB driver that you are using ? That would be the first place to start I would think. If you have a driver, you have to know how to access it's API.

If you mean native Windows USB drivers, for example, then you need to find the API functions that pertain to using the USB.

I've never done anything with USB, but have written drivers and programs to use drivers...so that would be step 1.

Thanks for the start. MS are trying to sell me MSDN membership for £2000 at the moment so I can have access to WinAPI. I have already bought DriverX USB module for C++ but without OEM camera info I cannot use it. Looks loke I have to go the API route.

Check out TWAIN. It has some APIs that could help you get started with webcam stuff (if your webcam supports it).
