In my application, which will be installed on a tablet or laptop, I need a command button which will take a photograph.
As I understand it, these photos will always automatically be stored in a specific folder. Is this possible? Is there someone who has done this and willing to share the source?

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.

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?

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.
