Download

I want to download the following files: mddiag.dat, mddiag.k1, mddiag.k2 and be able to select the destination folder.

Note: I have a window registry that can give me the folder where I want to save the download.

That is a problem with modern browsers, ;they do not give the option for you to select where to download to, they only download to a preset location. This cannot be overwritten through the web page for security reasons.

I have a download page that have a search bar to display de data
I want that a search some data and that the page refresh every 5 minutes to see if is new data
of that search

use data assist search to create the search form and add code to reload the results page.

see this page for details:
