This is so much easier with the Vision Toolkit, but it is expensive for such a simple task, so here goes:
1. You want to use Snap, which will acquire a single image. Look at the IMAQ examples, which will show you how to create an image, Snap it, convert it to an array, and display it using an intensity graph.
2. Instead of using an intensity graph, you could use a picture control to display the array. You can also save Windows bitmaps using the picture control pallette. If it is a gray image, it will be saved as a standard 8 bit image. If it is color, it will be save in 24 bit format.
