Browser Engine

In order to use Edge as the browser engine, the WebView2 Runtime must be downloaded and installed. WebView2 Runtime is an Edge installation that is designed for embedding the engine in third party applications (R:BASE). It recommended to download and install the Evergreen Standalone Installer (x86 installer). Your operating system may already have WebView2 Runtime installed. To check if WebView2 Runtime is installed, use the CHECK_WEBVIEW2 parameter with the GETPROPERTY command (below). The "vWebView2Install" variable value will be either "OK" or "NOT FOUND".

 

GETPROPERTY APPLICATION CHECK_WEBVIEW2 'vWebView2Install'

SHOW VAR vWebView2Install

 

Web Browser Emulation

A PROPERTY APPLICATION parameter has been introduced to specify the Internet Explorer version to emulate, when displaying Web Browser controls in forms.

 

PROPERTY APPLICATION WEB_BROWSER_EMULATION <value>

 

The emulation value may be one of the following:

 

11000 = Internet Explorer 11

10000 = Internet Explorer 10

9000 = Internet Explorer 9

8000 = Internet Explorer 8

7000 = Internet Explorer 7

RESET = Resets the emulation value

 

Note: The WEB_BROWSER_EMULATION must be set before any instance of a Web Browser control is created. Any change to WEB_BROWSER_EMULATION after a Web Browser has been created will take effect the next time the R:BASE program is opened.

 

Examples:

 

PROPERTY APPLICATION WEB_BROWSER_EMULATION 11000

 

PROPERTY APPLICATION WEB_BROWSER_EMULATION RESET
