I saw Veer’s answer. I think it’s right, but it did not I work for me. Maybe I am using .NET 4 and am using 64x OS so kindly check this.
You may put in setup or check it in start-up of your application:
private void Form1_Load(object sender, EventArgs e)
{
var appName = Process.GetCurrentProcess().ProcessName + ".exe";
SetIE8KeyforWebBrowserControl(appName);
}
private void SetIE8KeyforWebBrowserControl(string appName)
{
RegistryKey Regkey = null;
try
{
// For 64 bit machine
if (Environment.Is64BitOperatingSystem)
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
else //For 32 bit machine
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
// If the path is not correct or
// if the user haven't priviledges to access the registry
if (Regkey == null)
{
MessageBox.Show("Application Settings Failed - Address Not found");
return;
}
string FindAppkey = Convert.ToString(Regkey.GetValue(appName));
// Check if key is already present
if (FindAppkey == "8000")
{
MessageBox.Show("Required Application Settings Present");
Regkey.Close();
return;
}
// If a key is not present add the key, Key value 8000 (decimal)
if (string.IsNullOrEmpty(FindAppkey))
Regkey.SetValue(appName, unchecked((int)0x1F40), RegistryValueKind.DWord);
// Check for the key after adding
FindAppkey = Convert.ToString(Regkey.GetValue(appName));
if (FindAppkey == "8000")
MessageBox.Show("Application Settings Applied Successfully");
else
MessageBox.Show("Application Settings Failed, Ref: " + FindAppkey);
}
catch (Exception ex)
{
MessageBox.Show("Application Settings Failed");
MessageBox.Show(ex.Message);
}
finally
{
// Close the Registry
if (Regkey != null)
Regkey.Close();
}
}
You may find messagebox.show, just for testing.
Keys are as the following:
11001 (0x2AF9) – Internet Explorer 11. Webpages are displayed in IE11
edge mode, regardless of the!DOCTYPE
directive.11000 (0x2AF8) – Internet Explorer 11. Webpages containing
standards-based!DOCTYPE
directives are displayed in IE11 edge mode.
Default value for IE11.10001 (0x2711)– Internet Explorer 10. Webpages are displayed in IE10 Standards
mode, regardless of the!DOCTYPE
directive.10000 (0x2710)– Internet Explorer 10. Webpages containing standards-based
!DOCTYPE

value for Internet Explorer 10.9999 (0x270F) – Internet Explorer 9. Webpages are displayed in IE9
Standards mode, regardless of the!DOCTYPE

directives are displayed in IE9 mode.8888 (0x22B8) – Webpages are displayed in IE8 Standards mode,
regardless of the!DOCTYPE
directive.8000 (0x1F40) – Webpages containing standards-based
!DOCTYPE
directives are displayed in IE8 mode.7000 (0x1B58) – Webpages containing standards-based
!DOCTYPE
directives are displayed in IE7 Standards mode.
Reference: MSDN: Internet Feature Controls
I saw applications like Skype use 10001. I do not know.
NOTE
The setup application will change the registry. You may need to add a line in the Manifest File to avoid errors due to permissions of change in registry:
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
UPDATE 1
This is a class will get the latest version of IE on windows and make changes as should be;
public class WebBrowserHelper
{
public static int GetEmbVersion()
{
int ieVer = GetBrowserVersion();
if (ieVer > 9)
return ieVer * 1000 + 1;
if (ieVer > 7)
return ieVer * 1111;
return 7000;
} // End Function GetEmbVersion
public static void FixBrowserVersion()
{
string appName = System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetExecutingAssembly().Location);
FixBrowserVersion(appName);
}
public static void FixBrowserVersion(string appName)
{
FixBrowserVersion(appName, GetEmbVersion());
} // End Sub FixBrowserVersion
// FixBrowserVersion("<YourAppName>", 9000);
public static void FixBrowserVersion(string appName, int ieVer)
{
FixBrowserVersion_Internal("HKEY_LOCAL_MACHINE", appName + ".exe", ieVer);
FixBrowserVersion_Internal("HKEY_CURRENT_USER", appName + ".exe", ieVer);
FixBrowserVersion_Internal("HKEY_LOCAL_MACHINE", appName + ".vshost.exe", ieVer);
FixBrowserVersion_Internal("HKEY_CURRENT_USER", appName + ".vshost.exe", ieVer);
} // End Sub FixBrowserVersion
private static void FixBrowserVersion_Internal(string root, string appName, int ieVer)
{
try
{
//For 64 bit Machine
if (Environment.Is64BitOperatingSystem)
Microsoft.Win32.Registry.SetValue(root + @"\Software\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", appName, ieVer);
else //For 32 bit Machine
Microsoft.Win32.Registry.SetValue(root + @"\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", appName, ieVer);
}
catch (Exception)
{
// some config will hit access rights exceptions
// this is why we try with both LOCAL_MACHINE and CURRENT_USER
}
} // End Sub FixBrowserVersion_Internal
public static int GetBrowserVersion()
{
// string strKeyPath = @"HKLM\SOFTWARE\Microsoft\Internet Explorer";
string strKeyPath = @"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer";
string[] ls = new string[] { "svcVersion", "svcUpdateVersion", "Version", "W2kVersion" };
int maxVer = 0;
for (int i = 0; i < ls.Length; ++i)
{
object objVal = Microsoft.Win32.Registry.GetValue(strKeyPath, ls[i], "0");
string strVal = System.Convert.ToString(objVal);
if (strVal != null)
{
int iPos = strVal.IndexOf('.');
if (iPos > 0)
strVal = strVal.Substring(0, iPos);
int res = 0;
if (int.TryParse(strVal, out res))
maxVer = Math.Max(maxVer, res);
} // End if (strVal != null)
} // Next i
return maxVer;
} // End Function GetBrowserVersion
}
using of class as followed
WebBrowserHelper.FixBrowserVersion();
WebBrowserHelper.FixBrowserVersion("SomeAppName");
WebBrowserHelper.FixBrowserVersion("SomeAppName",intIeVer);
you may face a problem for in comparability of windows 10, may due to your website itself
you may need to add this meta tag
<meta http-equiv="X-UA-Compatible" content="IE=11" >
Enjoy 🙂
