browse with mod harbour

Hello friends,

I am showing an example of how you can simulate an xBrowser on the internet with mod harbour.
Silvio designed a template.
Here you can see that the Silvio EXE works locally and that we access the same database via the Internet.
The program was originally created with set exclusive on,
there is an access problem from the Internet if the local EXE is open.
I change that quickly in the program.
But it is important that you see that the record locking and the file locking are working properly.
The edit function has not yet been programmed in the EXE, so we are changing the data with the dBase editor.

You can see the same data offline and online.

Hi Otto.
Take a look at the scroller capabilities. Used with datatables is really fast.

Hello Massimo,
Thank you. Yes scrolling is very fast in datatables.
I use it in other programms like this one:

Code: Select all  Expand view

  t = $('#example').DataTable({
            "searching": false,
            "bInfo" : false,
            "order": [[ 0, 'desc' ]],
            "scrollY":       '20vh',
            "scrollCollapse": true,
            "paging":         false,

Best regards,
Otto
