  • Is there a more efficient way to set variables on a RadioButton's CheckChanged event?

    - by C Patton
    I have 16 radio buttons in an application of mine.. I have to set a variable based on which one was selected.. and I've produced some very ugly code doing this.. private void Foo_CheckedChanged(object sender, EventArgs e) { convertSource = 1; } private void Bar_CheckedChanged(object sender, EventArgs e) { convertSource = 2; } private void Baz_RadioButton_CheckedChanged(object sender, EventArgs e) { convertSource = 3; } Now, I've been thinking about it and to be honest I thought there might have been a way to do it with a switch.. I just can't conceptualize it in my mind. If anyone could show me a more efficient way of doing this, I'd really appreciate it. It's just really bugging me that such a simple thing as this is taking up fifty to seventy lines of code. thanks, cpatton

  • Check if 'onload' would have fired already?

    - by thomasrutter
    Hello, I have a situation where I'd like to set an onload handler for a script element, but it is possible that the script element has already loaded before I do so. If it's already loaded, I'd like to detect that and run my handler immediately. What would be a reliable way of checking a script element's onload state after the fact? BTW I know that IE uses readyState instead of an onload event so I don't need help for that.

  • How to coach a developer with dyslexia to improve his spelling and grammar capabilities?

    - by Uwe Keim
    Just having read this question regarding developers with dyslexia, I still have some open questions on how to deal with it: I am working on a project sinc approx. 6 month with a new developer who just finished university. I see that the code quality is high, what he's missing is the ability to write texts (even short ones) in an error-free manner (both, syntax and grammar errors). He is working on some UI stuff (VS.NET 2010, ASP.NET 4) and, beside coding, has to write short text for labels, buttons, grid view headers, page titles, etc. Since even those texts have errors inside, no matter how much I try to discuss the need for a professional, text-error-free UI, he seems to not manage to get this right, although he really tries. So my questions are: Are there any hints how he (or I) should proceed to enhance the text quality? Do you know any tools (like inline spell checkers) for VS.NET to highlight syntax and grammar errors? (We are working on a German-only UI, if this is important to know)

  • The Webbrowser DocumentComplited event wont fire c#

    - by Igal B.
    Hi. I have a problem using C# Webbrowser control. the problem is with the event DocumentComplited. Usually the event works fine. the problem is with this page:http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html when I (automatically) press on "add" the control navigates to:http://www.voiproblem.com/emulators/Netgear/WGR614v6/pforward.html. but it never firing the DocumentComplited event. I build a simple application that does the same and there it works fine. I mean when the app invokes InvokeMember("click") it does go to the DocumentComplited event. in my real app it doesnt. anyone can help me to figure it up what is the problem? thanks. <code> private void button1_Click(object sender, EventArgs e) { webBrowser1.Navigate("http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html"); } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { HtmlElement elm = webBrowser1.Document.GetElementById("Add"); if (elm != null) webBrowser1.Document.GetElementById("Add").InvokeMember("click"); } </code>

  • ModalPopupExtender OnShow Event

    - by Thomas
    When clicking a button, I have a ModalPopupExtender (Panel) that gets displayed. I can't seem to trigger any event during that process. Adding an event to the button that opens the ModalPopupExtender doesnt work, as it never triggers. Adding the button as a trigger in my UpdatePanel also doesnt work. Scenario: I have a gridview with a button outside of the gridview. Clicking the button opens up a ModalPopupExtender which needs to display the checkboxes clicked on the gridview. I have the code to get the checkboxes clicked on the Gridview, however I cant seem to use an event during the process of opening the ModalPopupExtender.

  • Why wont this JS code work if its all on the same line?

    - by culov
    I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

  • Test whether image loaded correctly with JavaScript

    - by johkar
    I have an image deployed on several application servers (green up arrow: uparrow.gif). I have an application server status page where I list out all the servers and with a corresponding image where the image's source is the uparrow.gif for that server. If the image does not load (server down) I would like to switch to a red down arrow (downarrow.gif). Is there a way to check whether an image loaded or not with straight JavaScript (no JS libraries etc)? I would imagine I would set an interval for it to continue checking if the user were on the page. Thanks.

  • Winforms panel event after scroll

    - by Charlie boy
    Hello I have a panel in wich I do a bounch af rater complex drawing in the paint event. Since the drawing-code is kind of heavy, it gets rather twitchy when I scroll the panel, since the paint event is raised in such short intervals. My question is really this; Can i capture evnts such as "on scroll start" and "on scroll end" on a winforms control? If so, I could then just pause the drawing-code until the scroll is complete. Thanks in advance!

  • Javascript Mouseover bubbling from children

    - by Nicky De Maeyer
    Ive got the following html setup: <div id="div1"> <div id="content1">blaat</div> <div id="content1">blaat2</div> </div> it is styled so you can NOT hover div1 without hovering one of the other 2 divs. Now i've got a mouseout on div1. The problem is that my div1.mouseout gets triggered when i move from content1 to content2, because their mouseouts are bubbling. and the event's target, currentTarget or relatedTarget properties are never div1, since it is never hovered directly... I've been searching mad for this, but I can only find articles and solutions for problems who are the reverse of what I need. It seems trivial but I can't get it to work... The mouseout of div1 should ONLY get triggered when the mouse leaves div1. One of the possibilities would be to set some data on mouse enter and mouseleave, but I'm convinced this should work out of the box, since it is just a mouseout... EDIT: bar.mouseleave(function(e) { if ($(e.currentTarget).attr('id') == bar.attr('id')) { bar.css('top', '-'+contentOuterHeight+'px'); $('#floatable-bar #floatable-bar-tabs span').removeClass('active'); } }); changed the mouseout to mouseleave and the code worked...

  • Windows Phone 7 Developer Tools &ndash; January 2011 Update

    - by TechTwaddle
    Note: I am currently in the process of relocating my blog from http://www.geekswithblogs.net/techtwaddle to my new address at http://www.techtwaddle.net I suggest you point your feed readers to the new address as I slowly transition to my new shared-hosted, ad-free wordpress blog :) If you haven’t heard already, the Jan 2011 update of the windows phone 7 developer tools is out, er, in Feb. You can download the installation files from here, http://www.microsoft.com/downloads/en/details.aspx?FamilyID=49b9d0c5-6597-4313-912a-f0cca9c7d277 The performance increase with the new emulator is clearly noticeable and the first time deploy is real quick! The emulator image should also be a precursor to the windows phone 7 OS update that we’ve been waiting for ever. The emulator image includes copy-paste functionality which is enabled by default on all textboxes, password boxes and edit controls within web browser control, so existing apps get this feature for free. Go ahead and give the new tools a try. If you want to experiment more you might be interested in a unlocked emulator image, follow the link for more information. http://windowsphonehacker.com/latest_windows_phone_7_emulator_unlocked-02-05-11.php

  • How to call an programmatically generated event for wxRadioButton in wxWidgets ?

    - by Jakub Czaplicki
    I am trying to programmatically change a value of a wxRadioButton in a way the user would do it. A value change doesn't call the event corresponded to the button, and it make sense since the documentation says it clearly: wxRadioButton::SetValue void SetValue(const bool value) Sets the radio button to selected or deselected status. This does not cause a wxEVT_COMMAND_RADIOBUTTON_SELECTED event to get emitted. So the question is how can I call an programmatically generated event for a wxRadioButton ? I guess that it's something to do with: wxWindow window->AddPendingEvent(wxEvent *event ) A simple example would be greatly appreciated.

  • How can I share an OnEnter event for a TcxGrid ?

    - by Roland Bengtsson
    I want to standardize the behaviour on an Devexpress TcxGrid. So I have a unit ClientData with a event: procedure TClientData.grdOnEnter(Sender: TObject); begin mnuCxGridStandardMenu.Grid := TcxGrid(Sender); end; If I try to use that event from a TcxGrid.OnEnter event in another unit it refuse to work. If I paste in ClientData.grdOnEnter then a dialog says it is not an valid identifier. Is it possible to share an event for several units in Delphi 2007 ?

  • Access event.target in IE8 unobstrusive Javascript

    - by Mirko
    The following function gets the target element in a dropdown menu: function getTarget(evt){ var targetElement = null; //if it is a standard browser if (typeof evt.target != 'undefined'){ targetElement = evt.target; } //otherwise it is IE then adapt syntax else{ targetElement = evt.srcElement; } //return id of element when hovering over or if (targetElement.nodeName.toLowerCase() == 'li'){ return targetElement; } else if (targetElement.parentNode.nodeName.toLowerCase() == 'li'){ return targetElement.parentNode; } else{ return targetElement; } Needless to say, it works in Firefox, Chrome, Safari and Opera but it does not in IE8 (and I guess in previous versions as well). When I try to debug it with IE8 I get the error "Member not Found" on the line: targetElement = evt.srcElement; along with other subsequent errors, but I think this is the key line. Any help will be appreciated.

  • Why does a checkbox's "checked" attribute return the opposite of it's actual value on click event?

    - by Kappers
    I've got the following HTML <li><input type="checkbox" /><label>This is the label!</label></li> I bound a click event to the li, and let the click event bubble up to the li before doing anything else. $('li').each(function(i){ var item = $(this); var checkbox = $("input[type='checkbox']", item); item.bind('click', function(e){ var isChecked = checkbox.is(':checked'); console.log(isChecked); e.stopPropagation(); }); }); Starting with an unchecked checkbox, when the click event fires, isChecked returns true when I click on the checkbox, but returns false when I click on the label or li. Does anyone know why?
