Title: Hide Webcam after photo is taken
Post by: rjolda on May 21, 2025, 12:46:25 PM

Hi all,
Using NT14.21 , Clarion11.
I have a form with a Display Field - DisplayPhoto which displays the photo when the picture is taken. 
On the same screen I have a TakePhoto button and a Webcam field which uses the environment Camera to take a photo (AON:ThisPicture)  and display it in the DisplayPhoto field.
My TakePhoto Button has the embed:
  p_web.SSV('PhotoDone', 'YES') ! we use this to display buttons - 1= we have taken picture -display ?Crop Photo button
 this button is set to Reset the valued of AON:ThisPicture ( which is the field equate that stores the picture)

My Webcam field (equate AON:ThisPicture) has the following hide statement:   p_web.GSV('PhotoDone') ='YES'

What I am finding is that the photo is taken and displays, the webcam display is gone and then the screen flickers and the webcam is back on display as if the webcam is set to ALWAYS display no matter what the programmer (like me) is trying to do.

Anyone with insights on this?
THanks,
Ron

Hi, are you refreshing the AON:ThisPicture control when pressing the TakePhoto Button?

Hi Bruce,
My Webcam field (equate AON:ThisPicture) has the following hide statement:
Hide if Clarion:  p_web.GSV('PhotoDone') ='YES'

I have the AON:ThisPicture value in the Reset box for TakePhoto button.  The Take Photo button also sets: p_web.SSV('PhotoDone') ='YES')

HI
With Bruce's help I found out that the TakePicture button is dedicated to javascript which runs and WILL NOT SEND a value to the server. 
By putting the hide condition and then the refresh fields in the WEBCAM field!  That was the trick.
