You can use the Kodak/Wang image controls if the camera has a TWAIN driver. There is an atricle on the Wiki that would help you get it setup. There is a form in the files section here that should help.
Since you mention image of an eye, if you are trying to do biometric identification you are going to need something better than the typical digital camera.
>Is it possible to capture images directly from a digital camera and store it in VFP 7. I have'nt the faintest idea as to how to get started on this. for example, Optical Shots of the eye.
