  • Are "proxy properties" good style?

    - by erlando
    I have a class with a string property that's actually several strings joined with a separator. I'm wondering if it is good form to have a proxy property like this: public string ActualProperty { get { return actualProperty; } set { actualProperty = value; } } public string[] IndividualStrings { get { return ActualProperty.Split(.....); } set { // join strings from array in propval .... ; ActualProperty = propval; } } Is there any risks I have overlooked?

  • MODX parse error function implode (is it me or modx?)

    - by Ian
    Hi, I cannot for the life of me figure this out, maybe someone can help. Using MODX a form takes user criteria to create a filter and return a list of documents. The form is one text field and a few checkboxes. If both text field and checkbox data is posted, the function works fine; if just the checkbox data is posted the function works fine; but if just the text field data is posted, modx gives me the following error: Error: implode() [function.implode]: Invalid arguments passed. I've tested this outside of modx with flat files and it all works fine leading me to assume a bug exists within modx. But I'm not convinced. Here's my code: <?php $order = array('price ASC'); //default sort order if(!empty($_POST['tour_finder_duration'])){ //duration submitted $days = htmlentities($_POST['tour_finder_duration']); //clean up post array_unshift($order,"duration DESC"); //add duration sort before default $filter[] = 'duration,'.$days.',4'; //add duration to filter[] (field,criterion,mode) $criteria[] = 'Number of days: <strong>'.$days.'</strong>'; //displayed on results page } if(!empty($_POST['tour_finder_dests'])){ //destination/s submitted $dests = $_POST['tour_finder_dests']; foreach($dests as $value){ //iterate through dests array $filter[] = 'searchDests,'.htmlentities($value).',7'; //add dests to filter[] $params['docid'] = $value; $params['field'] = 'pagetitle'; $pagetitle = $modx->runSnippet('GetField',$params); $dests_array[] = '<a href="[~'.$value.'~]" title="Read more about '.$pagetitle.'" class="tourdestlink">'.$pagetitle.'</a>'; } $dests_array = implode(', ',$dests_array); $criteria[] = 'Destinations: '.$dests_array; //displayed on results page } if(is_array($filter)){ $filter = implode('|',$filter);//pipe-separated string } if(is_array($order)){ $order = implode(',',$order);//comma-separated string } if(is_array($criteria)){ $criteria = implode('<br />',$criteria); } echo '<br />Order: '.$order.'<br /> Filter: '.$filter.'<br /> Criteria: '.$criteria; //next: extract docs using $filter and $order, display user's criteria using $criteria... ?> The echo statement is displayed above the MODX error message and the $filter array is correctly imploded. Any help will save my computer from flying out the window. Thanks

  • How do you get the host address and port from a System.Net.EndPoint?

    - by cyclotis04
    I'm using a TcpClient passed to me from a TcpListener, and for the life of me I can't figure out a simple way to get the address and port it's connected to. The best I have so far is _client.Client.RemoteEndPoint.ToString(); which returns a string in the form FFFF::FFFF:FFFF:FFF:FFFF%00:0000. I've managed to extract the address and port using Regular Expressions, but this seems like overkill. What am I missing?

  • Google Maps API 3 How to call initialize without putting it in Body onload

    - by Bex
    Hi I am using the google maps API and have copied the examples and have ended up with a function called "initialize" that is called from the body onload. I am using the maps in a few different user controls, which are placed within content place holders, so the body tag is in the master page. Is there a way of calling initialize directly in the usercontrol rather than having to place an onload on the masterpage? Ideally I want my user control to be a stand alone control that I can just slot into pages without trying to access the master page body onload. I have tried calling the Initialize function from my page load of the user control (by adding a start up script), but the map doesn't appear. Any suggestions? My code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">/script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> var map; var geocoder; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(51.8052184317649, -4.965819906250006); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); $.ajax({ type: "POST", url: "/GoogleMapsService.asmx/GetPointers", contentType: "application/json; charset=utf-8", dataType: "json", beforeSend: function () { $(".loadingData").html("<p>Loading data..</p>"); }, complete: function () { $(".loadingData").html(""); }, cache: true, success: mapPoints, error: onError }); } function onError(xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(xhr.responseText); } function mapPoints(response) { if (response.d != null) { if (response.d.length > 0) { for (var i = 0; i < response.d.length; i++) { plotOnMap(response.d[i].Id, response.d[i].Name, response.d[i].Lat, response.d[i].Long, response.d[i].ShortDesc) } } } } and on my test master page: <body onload="initialize()"> <form runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager> <asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder> </form> </body>

    - by mikep

  • Tuples vs. Anonymous Types vs. Expando object. (in regards to LINQ queries)

    - by punkouter
    I am a beginner who finally started understanding anonymous types. (see old post http://stackoverflow.com/questions/3010147/what-is-the-return-type-for-a-anonymous-linq-query-select-what-is-the-best-way-t) So in LINQ queries you form the type of return value you want within the linq query right? It seems the way to do this is anonymous type right? Can someone explain to me if and when I could use a Tuple/Expando object instead? They all seem very simliar?

  • Grouped Select in Rails

    - by Neil Middleton
    Simple question really - how do I use the select(ActionView::Helpers::FormOptionsHelper) with grouped options? I have got it working with a select_tag (ActionView::Helpers::FormTagHelper) but I would really like to have it using a select tag to match the rest of the form. Is this possible? My options look like this: [ ['Group 1', ["Item 1", "Item 2", "Item 3"]], ['Group 2',["Item 1", "Item 2", "Item 3", "Item 4"]] ] whilst my view is currently: %tr#expense %td = f.text_field :value = f.hidden_field :type, :value => mode

  • get rid of red X in IE for non-existing images

    - by hubertg
    I have a 3rd website (Confluence) which references images which are secured by a login. If the current user is logged in the image is shown if not the image url would redirect to a login form. Example When you enter this url in the browser a redirect to the login page is done. The problem now: IE shows a the dreaded red X icon for the image even though there should be just nothing (like in Firefox). Anyone knows how to get around this?

  • Hibernate cascade debug options

    - by Chris
    I have run into various StackOverflowErrors which occur during cascading. These have been extremely time consuming in debugging because I don't know which properties are being cascaded to cause this recursive behavior. Does anyone know of a log setting or some other form of debugging which could tell me specifically what properties are being cascaded?
