webserver example 79

[harold peters]

Has anyone ever got  example 79 to work (camera, barcode, QR scanning)? I am trying to implement QR scanning in a webserver app without success (clarion 11.1 Nettalk 14.37)

seems to work here. Note that it *has* to be on a secure connection (or 127.0.0.1).

HI Harold,
I have QR code scanning and camera taking pictures using a NT web server.  Using Easy Cam to do some of this.  If you test locally 127.0.0.1 with you barcode scanner connected, then it will work fine.  No security certificate needed.  I would suggest you do this on your local machine first to get it going ( run your web server on local machine with qr reader connected).    You essentially have 2 options - read it through a USB interface (HID) and get text returned into a text box or use a USB-Serial interface.  I did a small show and tell on this about 2 years ago on net talk webinar.  If you use the HID (USB) interface, then you can test your code reader in any text box - just open something in notepad and scan something and the HID interface will place it right into the active document.
