how make my c# web browser to support html5

OK, found the answer (at least for the case of hosting the Webbrowser control in C++)

You must add a registry entry to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

For 32bit OS


*******OR*******

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

For 64bit OS

and this entry must be a DWORD, with the name being the name of your executable, that hosts the Webbrowser control; i.e.:

myappname.exe (DON'T USE "Contoso.exe" as in the MSDN web page...it's just a placeholder name)

Then give it a DWORD value, according to the table on:

http://msdn.microsoft.com/en-us/library/ee330730(v=vs.85).aspx#browser_emulation

I changed to 11001 decimal or 0x2AF9 hex --- (IE 11 EMULATION)

WHY that isn't the DEFAULT value (When you have IE 11 installed -- or whatever version), instead of IE 7 or 8, I'll never know...

PROBLEM SOLVED (at least in this case!)
