HTML picture supporting HTML5 and CANVAS

[maurodx]

I need to display an HTML page inside a Zenon Picture but from what I've discovered the element inside the HTML type picture is based on an old IE that doesn't support latest javascript/html capabilities.

Do you have some solutions regarding this?

Hello maurodx,

In fact, the HTML screen in zenon doesn't use a specific ("old") IE version or the default browser installed in the operating system.

Instead it uses the pre-installed rendering engine of Microsoft called "Microsoft Web Browser Control". This program emulates the Internet Explorer. The functionality of the implemented web browser like installed plugins, Javascript, activeX elements and so on, depends on which IE version is rendered by the Microsoft Web Browser Control.

You can find the entries in the Windows registry (64bit):

• HKEY_LOCAL_MACHINE (or HKEY_CURRENT USER)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULA TION.

For example, the value for the IE7 is (7000), for IE8 is (8000), for IE9 is (9000), for IE10 is (10000) and IE11 (11000).

You can enter this values manually, but pay attention which Windows version is in use. The registry path for 32bit version is:

• HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULA TION.

In Windows x64 insert the "zenrt32.exe" into the 32bit and 64bit registry paths with the decimal value e.g. 11000 (picture attached).

Then you can use javascript/HTML in the HTML screen.

I wish you good luck,
