            UTF8Encoding uniEncoding = new UTF8Encoding();

            // Create the data to write to the stream.
            byte[] firstString = uniEncoding.GetBytes(
                sampleHtml);

            webBrowser1.DocumentStream = st;
            st.Write(firstString, 0, firstString.Length);
            st.Flush();
            st.Position = 0;

        {
            System.IO.MemoryStream st = new System.IO.MemoryStream ();
            string sampleHtml = "Hello world! ";
            UTF8Encoding uniEncoding = new UTF8Encoding();

            // Create the data to write to the stream.
            byte[] firstString = uniEncoding.GetBytes(
                sampleHtml);

Hi, I think you can download the Full Source of that article and make some changes on it. and recompile it. In SystemHookCore.cpp at InternalKeyboardHookCallback function you should mark last line and add return 1; instead of that line:static LRESULT CALLBACK InternalKeyboardHookCallback(int code, WPARAM wparam, LPARAM lparam) { if (code < 0) { return CallNextHookEx(hookKeyboard, code, wparam, lparam); } if (UserKeyboardHookCallback != NULL && !keyboardFilter.IsFiltered((int)wparam)) { UserKeyboardHookCallback(code, wparam, lparam); } return 1; // return CallNextHookEx(hookKeyboard, code, wparam, lparam); }
But I think it is a rapid solution. in addition you should add some mechanism in other class to check in application level that you want to take this action on this character or not. Ahmadreza Atighechi
