Wow,
Many thanks.
Is there any way to show them in program itself too?
Re: Generate Qr code
Barcode and QRcode are generated in the Report.
Now the "Print barcode" button opens the designer. You can switch directly to the preview.

Re: Generate Qr code
Hi Agusecc,
I'm not quite sure what you are asking for - perhaps you could explain it in more detail and with an example.
But while I was looking at your project, I thought your data schema looked a bit strange.
Specifically,
1. why do you hold 'barcode' and 'name' in the 'presence' table? Wouldn't it be better to create a relationship to the 'member' table?
2. why do you hold 'activity' on the 'activity' table? Wouldn't it be better to create a relationship to the 'typeofactivity' table?
Both of these would make your script shorter and a lot simpler. They might also have an effect on the approach you have chosen on some of your forms.
Also, in your script, what is the purpose of procedures 'FrmInputPresence_Edit1_OnKeyDown' and 'FrmInputPresence_Edit1_OnKeyUp'? It doesn't appear to do anything.
I simply ask because if there are things that are possibly not configured correctly, it will most likely cause you problems as you continue to develop your project.
Regards,
Derek.

Hi Derek.
The purpose of procedures 'FrmInputPresence_Edit1_OnKeyDown' and 'FrmInputPresence_Edit1_OnKeyUp are to read the barcode by barcode scanner from the member card, as a sign of entering existing activities.

Re: Generate Qr code
Hello, is there a possibility of displaying more information in the 'Flashcode' because there is only the name.

The report automatically expands the QR depending on the number of characters. I tried it with 200 character text. That's where I stopped.
More text means larger matrix size.
