I realize this has nothing to do with VB but I usually get good
answers here and I'm hoping someone here might have some ideas on
this.

I have a situation where I want to take digital photos (snapshots -
not video) of the contents of boxes as they move along on a conveyor
system. I'm thinking that the photo would be taken at the same time
that I scan in a barcode that's on the side of the box. I'd then
associate the barcode with the .jpg image file and store it on a
computer's hard drive for later manual viewing.

Does anyone know of a camera that can be set up such that I can take
the picture under computer control and that can then immediately send
the resulting picture to the computer?

Any thoughts or suggestions will be greatly appreciated.

I'm doing a similar project for someone who wants to take photos of prints
coming off a print press. I'm using a video camera and simply grab a frame
when I need it. I'm using dot net though as this (DirectShow) is difficult
in vb6. It uses an external trigger so the operator can trigger when the pic
is taken.

The other option is to use a consumer level digital camera which is one
option I was going to investigate for the print press. Aquiring the picture
is easy but I haven't yet worked out how to trigger the camera from
software, although I haven't really tried that hard. Again this is difficult
in vb6 (WIA) but there is a com library with reduced functionality that is
quite good, you can use this library to aquire pictures but I don't think it
will trigger the shutter. It does have a method call for this but it throws
an error with the camera I have (I suspect the method is for scanners only).
