webbrowser using ie10 c# winform -

i want force webbrowser use ie10 in c# winform application. know there other questions i've read lot of them , don't know i'm wrong.

this code:

registrykey registrybrowser = registry.localmachine.opensubkey            (@"software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation", true);         registrybrowser.setvalue("myappname", 0x02710, registryvaluekind.dword); //even qword 

i've tried different ways set value like:

registrybrowser.setvalue("myappname", 1000, registryvaluekind.dword); //even qword , string registrybrowser.setvalue("myappname", 1000); //even 0x02710 

i write in costructor of main project before initializecomponent(). i've got admin permission set in .manifest file

thanks all, blackshawarna

edit: discovered registrykey.setvalue(...); created key in path:

(@"software\wow6432node\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation")  

even if instruction said: registry.localmachine.opensubkey (@"software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation", true);

i think happens because ie10 works on 32bit mode. don't understand why writes in path if specified 1 and, above all, why application doesn't work if open registry.localmachine.opensubkey(@"software\wow6432node....");

if run program in x64 mode, going properties/build/x64, won't write key in original path.

i had same problem app wrote value "hkey_local_machine\software\wow6432node\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation".

i changed localmachine currentuser , works.

string executablepath = environment.getcommandlineargs()[0]; string executablename = system.io.path.getfilename(executablepath);  registrykey registrybrowser = registry.currentuser.opensubkey    (@"software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation", true);  if (registrybrowser == null) {     registrykey registryfolder = registry.currentuser.opensubkey         (@"software\microsoft\internet explorer\main\featurecontrol", true);     registrybrowser = registryfolder.createsubkey("feature_browser_emulation"); } registrybrowser.setvalue(executablename, 0x02710, registryvaluekind.dword); registrybrowser.close(); 

the executablename "myappname.exe"

note: if webbrowser controls inside dll need specify hosting exe's name whatever might be, eg system.appdomain.currentdomain.friendlyname
