Yes, the process causes the same kind of headache for a built-in camera vs
an external USB camera. Here is the summary of taking pictures in VFP from
my sensor session last year:

CameraCaptureUi
- Only available in Windows Store Apps

MediaCapture
- Crashes, probably due to driver issue

TWAIN
- Complicated, hard to get drivers

Windows Image Aqcuisition
- Kind of works, but low resolution and camera keeps disappearing

HTML 5 getUserMedia
- Works in Edge and Chrome, but can‘t easily embed those


TWAIN is covered in the article from Mile Lewis, Windows Image Acquisition
is the news2news solution that is also on the FoxPro wiki. Using the camera
application gives much better pictures, but zero control over the image
taking process and picture location.

My experience with the API is hit and miss depending on the hardware.

I occasionally look for another solution.

Hello Chris and Darren

I have not yet had time to check out your responses, but I want to thank
you for the quick responses.

Do you think the process is the same for an in-built camera as it is for a
usb camera?

RE: Command button to take a photo

[Darren]

If you have an image on a form similar to the situation in the link below
then it is a relatively simple matter to use the API to define a rectangle
and capture that as a bitmap image file. Also relatively easy to convert to
other image formats using for example the offering in gdiplus. I am sure a
number of other options exist too. So yes - possible.
