Reading QRCodes

[reinaldocrespo]

Hello again Fiwinners;

Can anyone here read QR Codes?

This squared dot matrix dots and squares can store a lot of information. Given a QR code storing text, can we read it with fw or harbour? Is anyone here reading QR Codes?

Thank you.

Dear Reinaldo,

By the way, I found a great plugin for ChatGPT.
It creates a button that allows you to select a file and upload it as a knowledge base.
It uses async to read the file as text and split it into chunks of size 15,000, which are then sent.

Here is a video demonstrating how it works: https://www.youtube.com/watch?v=iR99LO28nzM

You can download the Chrome plugin, called "ChatGPT File Uploader," from this link: https://tinyurl.com/5n7rjhar

Reinaldo, sorry for off-topic, some time ago you share in this forum an class to twillio, to send sms, whatsapp, you still using this class? do you make updates to this? can you share?

best regards

Yes, sure.

I wrote methods to send texts and make phone calls but not to send via WhatsApp although it wouldn't be too hard to add. Keep in mind you will need a web hook set up to catch any incoming texts.

Here is that class:

#define ACCOUNT_SID  "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" //assigned by Twilio
#define AUTH_TOKEN   "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" //assigned by Twilio
#define TEL_FROM     "xxxxxxxxxxx"   //Your Twilio number


#INCLUDE "hbClass.ch"
#include "hbcurl.ch"

zbarimg is fantastic!

Reinaldo

Code: Select all  Expand view  RUN

c:\Program Files (x86)\ZBar\bin\zbarimg QRCODE.JPG  > TEXT.TXT

fast, accurate, never misses a beat

I loaded 2000 qr codes in my application so the name of the jpg and text in a short time

Thank to Antonio!

[Otto]

Marco,
>zbarimg is fantastic!
can you show an example how to use?

Thank you and best regards,
Otto

[MarcoBoschi]

Otto,
I create a BAT file and launch it (using __RUN)

Code: Select all  Expand view  RUN

cComando := '"c:\Program Files (x86)\ZBar\bin\zbarimg" ' + '"' + cFileJpg + '"' + + " > " + '"' + cFileTxt + '"'
cComando := cComando + crlf + "EXIT" + crlf

MEMOWRIT( "do_scan.bat" , cComando )

__RUN ( "START /MIN do_scan.bat" )
 

Then I read the content from file cFiletxt

Code: Select all  Expand view  RUN

IF FILE( cFileTxt )
   cLettura := MemoRead( cFileTxt )
ENDIF
 

Dear Otto zbarimg scan and decode image that I pass in command line
this is my last do_scan.bat

"c:\Program Files (x86)\ZBar\bin\zbarimg" "P:\Misuratori Fiscali\QR CODE\99MEY0xxxxx.jpg" > "P:\Misuratori Fiscali\QR CODE\TXT_LINK\99MEY0xxxxx.TXT"
EXIT

In command line after the name of file thad I have to decode I insert > and the name of file TXT to create containng the results of scan. Then I read this txt
