css - C# WebBrowser: draw circle? -
i'm writing 1 simple visualisation app , have 1 little problem: webbrowser.version returns build: 9600 major: 11 , despite can't use modern css3 features draw circle. below html code , output get. tried various methods found on google , nothing seems work. deleted unnecessary code, left part not working in webbrowser.
oh, btw, works when opened in standalone ie. tried `border-radius: 50%
<!doctype html> <html lang="en" xmlns="http://www.w3.org/1999/xhtml"> <head> <meta charset="utf-8" /> <title>main window</title> <style> .circle { border-radius: 10px; width: 20px; height: 20px; background: blue; } </style> </head> <body> <div class="circle"></div> </body> </html>
this because webbrowser class emulates ie , therefore have hkey setting version of ie used in emulation.
below couple of suggestions or alternatives.
meta tag
<meta http-equiv="x-ua-compatible" content="ie=10" /> add above html , try , force browser show content in ie10.
hkey change on machine
find below hkey's
hkey_local_machine\software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation hkey_local_machine\software\wow6432node\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation and change or add app values so
feature_browser_emulation "myappname.exe"=10000 hkey change in code
to same above within code, use following:
registrykey registrybrowser = registry.localmachine.opensubkey (@"software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation", true); registrybrowser.setvalue("myappname.exe", 10000, registryvaluekind.dword);
