How to fill text area and click on button using c#? -

-

i having problem filling text area , click on button using c# code... please give me example if have dont care if using webbrowser or watin or whatever...

<textarea class="textarea" placeholder="say something" style="overflow: hidden;"></textarea>    <div class="comment-submit-container"> <button class="comment-submit" type="submit">post comment</button> <img class="comment-submit-loading" width="16" height="16" src="www.notimportantlink.com" alt=""> </div>

this have tried using class..basically stackoverflow

webbrowser1.documenttext = "text classes"; webbrowser1.documentcompleted += new webbrowserdocumentcompletedeventhandler(webbrowser1_documentcompleted);  void webbrowser1_documentcompleted(object sender, webbrowserdocumentcompletedeventargs e)         {              foreach (htmlelement txt in webbrowser1.document.getelementsbytagname("textarea"))             {                 if (txt.getattribute("classname") == "textarea")                 {                     txt.setattribute("value", "adsasdassd");                    // messagebox.show("uneseno");                 }             }        foreach (htmlelement btn in webbrowser1.document.getelementsbytagname("button"))             {                 if (btn.getattribute("classname") == "comment-submit")                 {                     btn.invokemember("click");                     messagebox.show("kliknuto");                 }             }           }

as can see in html code there no id or name..

in watin can use find.byclass or index find elements

this flash button, not click it, proof of concept

var ie = new ie(); ie.goto(@"[link goes here"); ie.textfield(find.byclass("textarea")).typetext("words go here"); ie.button(find.byclass("comment-submit")).flash(2);

if class textarea not unique, can return elements of type , refernce index. eg: ie.textfields[0].typetext("words go here index");

or combine find criteria ie.textfield(find.byclass("textarea") && find.byindex(0)).typetext("words go here compound find");

.

html used

<html> <title>this title.</title> <body> <textarea class="textarea" placeholder="say something" style="overflow: hidden;"></textarea> <div class="comment-submit-container"> <button class="comment-submit" type="submit">post comment</button> <img class="comment-submit-loading" width="16" height="16" src="www.notimportantlink.com" alt=""> </div> </body> <html>

tested on watin 2.1, ie9, win7 64bit

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
