Hello,

I've been testing the potential of the tool and I'm enjoying it, but... when it comes to SQL, I think it's more complicated (backend). Is there a demo that shows the access to Mysql/Other with the main data access features, the typical CRUD?

Is PHP mastery necessary?

Is it possible to work with binary files?

Thanks

Hi @xpto. have you checked the includd samples under My Documents\VisualNeoWeb\Sample Apps ? (Some of them are compiled and published here)
In VisualNEO YouTube channel you will find a step by step simple database app.

Is PHP mastery necessary?

Not at all. neoPhp is an included plugin with many ready to use facilities.

Is it possible to work with binary files?

What do you mean exactly?

Best regards.

Thanks for the answer.

Example binary file in VB6:

Dim f As Long

f = FreeFile()

Open "C:\abc.dat" For Binary As #f

Put #f, , "This is the Test file."

Close #f

It would only be for local processing in situations where it is necessary to store data, but a complete SQL Database is not always necessary.

@xpto VisualNEO Web can read local binary data into a variable (using a File Input object) and save (download) it as a file. But, for security reasons, it's probably not possible to save data locally as you expect. Anyway take a look at the neoFileSystem plugin (only works on Chrome and Edge).
On the other side, you can send Base64 encoded files to the server and save them server side using neoPhpFileWriteFromBase64.

Regards.
