webbrowser using ie10 c# winform

Question

I want to force the webbrowser to use IE10 in my c# winform application. I know there are other questions like this but i've already read a lot of them and i don't know where i'm wrong.

This is my code:

RegistryKey registrybrowser = Registry.LocalMachine.OpenSubKey
           (@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
        registrybrowser.SetValue("myAppName", 0x02710, RegistryValueKind.DWord); //Even with QWord

I've tried different ways to set the value like:

registrybrowser.SetValue("myAppName", 1000, RegistryValueKind.DWord); //Even with QWord and String
registrybrowser.SetValue("myAppName", 1000); //even with 0x02710

I write it in the costructor of my main project before InitializeComponent(). I've got Admin permission set in the .manifest file

Thanks to all, BlackShawarna

EDIT: I discovered that the RegistryKey.SetValue(...); created a key in another path:

(@"SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION") 

even if my instruction said: Registry.LocalMachine.OpenSubKey (@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);

I think it happens because IE10 works on 32bit mode. However I don't understand why it writes in that path even if i specified another one and, above all, why my application doesn't work even if I open Registry.LocalMachine.OpenSubKey(@"Software\Wow6432Node....");

If I run my program only in x64 mode, going to properties/build/x64, it won't write the key in my original path.

Answer 1

I had the same problem that my app wrote the value to "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION".

I changed LocalMachine to CurrentUser and now it 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 is something like "myAppName.exe"

Note: If the WebBrowser Controls inside a DLL you need to specify the hosting EXE's name whatever that might be, eg System.AppDomain.CurrentDomain.FriendlyName

Answer 2

FEATURE_BROWSER_EMULATION "myAppName.exe"=10000 (or 0x02710) and not 1000.

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

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

It works for me
