[C#] Webbrowser - ie 버전 up

기존 .NET Framework에서 webbrowser는 IE 7버전이기에 js 오류가 날 수 있어 레지로 버전을 11로 향상 시킬 수 있다.

 

1. 레지등록 방법

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"프로그램이름.exe"=dword:00002ee1

xxx.reg로 만들어서 등록하면 해당 프로그램명은 ie 11로 사용
