Hello everyone.
In my country is requiring PC printed bills are adding a QR code.
Anyone know how to start something.

What is a QR code?

Hi, use this code......
/--------------------------------------------------------------------------------------------------
Function QRGenerator(cTexto, cPath, cBmp) // genera codigo qr
local cStr, cFile
LOCAL nResp

#Define DC_CALL_STD 0x0020

STATIC qrDLL

DEFAULT cPath := "BMP\"
DEFAULT cBmp := "QR.bmp"
DEFAULT cTexto := "SVITE SOFTWARE ADMINISTRATIVO"

IF !FILE("QRCodelib.Dll")
MsgStop("Sin Librería de Soporte","Improcedente")
Return(NIl)
EndIF

cStr := cTexto //"Texto a QR Code"
cFile := cPath + cBmp

qrDLL:=LoadLibrary("QRCodelib.Dll" )
nResp:=DllCall(qrDLL,DC_CALL_STD,"FastQRCode",cStr,cFile)
FreeLibrary(qrDLL)

RETURN (cFile)

Willy thanks for replying.
I have seen that there is a range of variants QRCodelib.Dll
And I found are extra, which you are using?
To avoid falling into bad experiences or headaches?

thanks

I found this same example, the forum fivewin brasil

Ottima funzione, molto utile !

E' possibile stampare il QRCode anche nei Report oltre che nelle printer

Good function to print a QrCode in oprn:...

Hi

How to read QR code data?

richard

In android I use barcode scanner
https://github.com/zxing/zxing

It works fine!
bye

Romeo,
Since I still use ReportPro in my programs I create a bmp file containing image of qrcode in a subfolder and from report I create an object
Picture source "File Name returned from an expression"
For instance in my table of articles there is a field named qrcode


Bye
