System.GotoURL(URL As String)

New in 2021r2

Supported for all project types and targets.

Uses the appropriate web browser application (based on the user’s Internet settings) to go to the HTTP URL specified.


Displays the supplied URL in the user's default web browser. If the browser is not open, it will launch the browser. Whether the URL opens in a new tab or a new window is controlled by the user's browser settings.

GotoURL is not global in a web app so you need to use WebControl.GotoURL or WebSession.GotoURL instead.

A URL is an address for Internet locations such as web sites, FTP and email addresses.

When used in a web app, if a web URL is passed, the current page is replaced with the page at the URL passed.

Some web browsers have a limit on the length of a URL. These are common prefixes:

URL Prefix Type Notes
http:// web site Displays in the default web browser.

ftp:// file transfer protocol Opens the default FTP application to download the specified file.
