我试图在Winforms Web浏览器控件中进行拼写检查.
这是我目前的C#代码:
try
{
String appname = Process.GetCurrentProcess().ProcessName + ".exe";
RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", RegistryKeyPermissionCheck.ReadWriteSubTree);
object ieVal = key.GetValue(appname, null);
MessageBox.Show(ieVal.ToString());
if (ieVal == null || (int)ieVal != 11001)
{
key.SetValue(appname, 11001, RegistryValueKind.DWord);
}
key.Close();
}
catch
{
MessageBox.Show("Registry stuff didn't work");
}
MessageBox.Show(webBrowser1.Version.ToString());
webBrowser1.DocumentText = "<html><head><body><div spellcheck=\"true\" style=\"width:100%; height:100%;\" contenteditable=\"true\"></div>"
+"<script>alert(navigator.userAgent);</script>"
+"</body></html>";
所以首先我设置正确的注册表项,以便浏览器模拟IE11
然后我添加一个div标签,其中spellcheck属性设置为true.
MessageBox.Show(webBrowser1.Version.ToString())节目的版本是:
11.0.9600.18525
在navigator.userAgent表明,JavaScript显示为:
Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
因此,似乎Web浏览器控件正在使用IE11.但是当我键入拼写检查时不起作用.
注意:当我用真正的IE运行那个html代码时,一切正常.
此外,navigator.userAgent实际浏览器上显示的是:
Mozilla/5.0 (Windows ….net c# spell-checking webbrowser-control internet-explorer-11
