I hope someone has a program example how to make a portrait picture with 
a webcam with my xBase V2 program.

In the past I was able to connect a flatbed scanner, there for I used 
eztwain3.ch from Atalasoft, but I am afraid that this firm has stopped 
in developing xBase tools.


Kind regards,
Frits Janse Kok

Also you can ask Jim Lee for his WEBCAM Class. Maybe Jimmy can upload this Class here.

You can find an example in:

    public.xbase++.activex
    Face extraction

Hi Diego,

I downloaded the Faces application and using ot4xb version 1.6.4.55 with 
Xbase 2.0 version 1079 built the Faces.exe.  I tried it on my Windows 10 
version 1607 Lenovo ThinkPad X1 Carbon and selected the "Integrated 
Camera" from the dropdown however mp1:= oDlg:oImage:currentResolution() 
returns NIL.  It appears that it is not successfully communicating with 
the built in camera.  I used the native windows "camera" application to 
confirm the camera's operation and also tried disabling my AV but the 
CurrentResolution() remains NIL and the camera image is black.

Any ideas?

Thanks... Jonathan

Hi Again,

I copied required files to my wife's laptop and ran it.  Initially I 
just got a green screen in the preview section but disabled her AV and 
it worked fine.  I then went back to my laptop and found that I had most 
likely not originally disabled the Kaspersky AV.  Works fine now!

Thanks... Jonathan

Hi Klaus and Diego,

Thank you very much for the information.
It was very helpfull.
Now I am able to use the webcam and take pictures.
I do not use the findface() part, because I only need a simple picture 
for a menbership card.

Regards,

Frits Janse Kok

what Windows Version are we talking about ?

i do have Problem with my Table PC (Lenovo 310 MiiX) under Windows 10 64Bit
and "Hello" WebCam.
Device-Box will open an show both CAM (Front/Rear) which i can select but i
can't Access it ?!
i do not have any Anti-Virus App (except Defender) on that Table PC.

---

i think i have read about VLC (VideoLan) and Video-Stream where you can take
a SnapShot.
have not tested it yet

---

i have test a Dot-Net Sample to access "Hello" WebCAM.
it work but i have not build interface to access it from "outside" ( Xbase++
using ActiveX )

---

so what i can say :
it depend on WebCAM and Windows Version where newer ("Hello" Type) may not 
work with AVI_CAP any more.
