USB Webcam commands control

I need to find where can get the commands control to programming a USB webcam (UVC webcam compliant and/or Non-UVC webcam compliant) with a programming language (C, Visual Basic, Visual C++). In this case the idea is develop a application that will control the webcam and the main idea is just take a FRAME every certain time, then the application shoud be able to display the image so the user should be able to see the picture

UVC (USB video class) is a standard, not _a_ camera.

To the OP: Unfortunately, I've only worked with the Linux driver and I gather from your post that you're using Windows. But you might want to look at

If nothing else, it will tell you what cameras follow the standard. Most cheap ones I've seen don't and require custom drivers (presumably with no standard API, if one at all).

QuickCam Messenger Vendor ID: 0x46D; Product ID: 0x8F0 this a NON-UVC Class, but I can use camara that uses the UVC standard.

I need to find the commands control, I mean commands like:

capture picture or take a pciture or send streaming video, basically the commads that the driver send to the device. The idea is develop an application (Visual C++) to take a pciture, but again I need the commands.

You absolutely do not. The entire point of installing a multi-gigabyte bloated operating system full of DLLs is to have access to APIs that insulate you from knowing or caring about the drivers underneath.
