Facebook评论文本框，按Enter键 [英] Facebook Comment Textbox, Pressing Enter Key

问题描述

我正在制作带浏览器的桌面应用程序，其中发布评论



需要按Enter键才能发表评论



现在我正在使用以下代码

i am making a desktop app with browser, which posts comment

the Enter button is required to be pressed to post the comment

right now i am using folowing code

txt = "how r u";
            string initial = "";
            HtmlDocument Document = (HtmlDocument)e.Argument;
            foreach (HtmlElement hform in Document.GetElementsByTagName("form"))
            {
                if (hform.GetAttribute("action") == "/ajax/ufi/modify.php")
                {
                    foreach (HtmlElement hbtnComment in hform.GetElementsByTagName("input"))
                    {
                        if (hbtnComment.GetAttribute("value") == "Comment")
                        {
                            hbtnComment.InvokeMember("click");
                            System.Threading.Thread.Sleep(1000);
                            Application.DoEvents();
                            break;
                        }
                    }

                    HtmlElement htxtArea = hform.GetElementsByTagName("textarea")[0];
                    initial = htxtArea.InnerText;
                    htxtArea.Focus();
                    System.Threading.Thread.Sleep(200);
                    Application.DoEvents();
                    htxtArea.InnerHtml = txt;// +"<input id=\"abc\" type=\"submit\">";
                    System.Threading.Thread.Sleep(200);
                    Application.DoEvents();
                    SendKeys.SendWait("{ENTER}");
                    System.Threading.Thread.Sleep(200);
                    Application.DoEvents();
}
}

此代码存在的问题是，它使用的是SendKeys函数，需要应用程序保持焦点，如果应用程序被最小化，那么这个代码不起作用



所以任何人都可以帮助我告诉我们如何让文本区域感觉到Enter按键已被按下

the problem with this code is, that it using SendKeys function, which requires the application to remain in focus, if the application is minimized then this code doesnt work

so kindly anyone who can help me in telling how we can make the text area feel that Enter key has been pressed
