[WB] Loading external files

Hello to All

I need to load and save some files in a longblob field in a table on a MySql db.

I know in Windev there is the "fselect" function to show you and browse your pc directories and then select a file and load/save its content .
But....How to do the same in Webdev??

I aware this could be a stupid question, but i didn't found useful information on help.

Thanks in advance.
