How can I use IME mode(only English) when I want?

[GGongM]

Hi,
I'm trying to cefshrap with winform.
I want to receive input in English only when I click a specific text box on the web.

So I use imm32.dll

[DllImport("imm32.dll")]
internal static extern bool ImmReleaseContext(IntPtr hWnd, IntPtr hIMC);

[DllImport("imm32.dll")]
public static extern Boolean ImmSetConversionStatus(IntPtr hIMC, Int32 fdwConversion, Int32 fdwSentence);

private static ChromiumWebBrowser m_browser;
public static bool ChangeIME(bool toogle) {
IntPtr hWnd = m_browser.Handle;
IntPtr himc = ImmGetContext(hWnd);
if (!toggle) {
ret = ImmSetConversionStatus(himc, 0, 0); //IME - English
}
else {
ret = ImmSetConversionStatus(himc, 1, 0); //IME - Korean
}
ImmReleaseContext(hWnd, himc)
}

Get the handle of the ChromiumWebBrowser well and the return value after conversion is true, but it does not change.
So I tried with the handle of the main form that floated the web, but it's the same.

How can I get English input by changing IME mode like pressing 'Language toggle key' ?

Chromium handles IME. I'm not sure what you are attempting is possible.

Try asking on https://www.magpcss.org/ceforum/index.php

IntPtr hWnd = m_browser.Handle;

That's the WinForms hande, the CEF Browser handle is obtained by a different method, see https://github.com/cefsharp/CefSharp/blob/4699eb5e0e6ba71c4f06442c5abfce5e20012c72/CefSharp.WinForms/WebBrowserExtensions.cs#LL57C62-L57C62
