  • jQuery WCF Service MVC2 VS2010 .NET 4.0 call with parameters fails

    - by AUSTX_RJL
    In Visual Studio 2010 I created a new Ajax enabled WCF Service [ServiceContract(Namespace = "TestWCFAjax.Bridge")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class Bridge { [OperationContract] public string DoWork() { return "jQuery WCF call without parameters from MVC2 works." ; } [OperationContract] public string DoWork1(string parm) { return parm + " jQuery WCF call with parameters from MVC2 fails"; } In the Home Controllers Index.aspx view I add the jQuery: function CallWebMethod() { $.ajax( { type: "POST", contentType: "application/json; charset-utf-8", url: "http://localhost:1452/Bridge.svc/DoWork1", dataType: "json", data: '{"parm":"test"}', error: jqueryError, success: function (msg) { alert("back"); var divForResult = document.getElementById("test"); divForResult.innerHTML = "Result: <b>" + msg.d + "</b>"; } }) } function jqueryError(request, status, error) { alert(request.responseText + " " + status + " " + error); } (using the built-in Web Server in VS 2010) When I call DoWork, it works fine. When I call DoWork1 it always returns "error undefined" and the WCF call never happens. I've tried every combination of: [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] I can think of and it does not help. I must be missing something simple. There are MANY posting about how to make this work, and other than the "no parameter" version, none have worked for me. Can anyone post a sample MVC2 jQuery 1.4 .NET 4.0 WCF VS2010 working sample or spot the likely error? Thanks.

  • LINQ - IEnumerable.Join on Anonymous Result Set in VB.NET

    - by user337501
    I've long since built a way around this, but it still keeps bugging me... it doesnt help that my grasp of dynamic LINQ queries is still shakey. For the example: Parent has fields (ParentKey, ParentField) Child has fields (ChildKey, ParentKey, ChildField) Pet has fields (PetKey, ChildKey, PetField) Child has a foreign key reference to Parent on Child.ParentKey = Parent.ParentKey Pet has a foreign key reference to Child on Pet.Childkey = Child.ChildKey Simple enough eh? Lets say I have LINQ like this... Dim Q = FROM p in DataContext.Parent _ Join c In DataContext.Child On c.ParentKey = p.ParentKey Consider this a "base query" on which I will perform other filtering actions. Now I want to join the Pet table like this: Q = Q.Join(DataContext.Pet, _ Function(a) a.c.ChildKey, _ Function(p As Pet) p.ChildKey, _ Function(a, p As Pet) p.ChildKey = a.c.ChildKey) The above Join call doesnt work. I sort of understand why it doesnt work, but hopefully it'll show you how I tried to accomplish this task. After all this was done I would have appended a Select to finish the job. Any ideas on a better way to do this? I tried it with the PredicateBuilder with little success. I might not know how to use it right but it felt like it wasnt gonna handle the joining.

  • How to manually check a YUI radio "button".

    - by alex
    <script type="text/javascript"> (function () { var ButtonGroup = YAHOO.widget.ButtonGroup; var onCheckedButtonChange = function (p_oEvent) { }; YAHOO.util.Event.onContentReady("mediaFilterButtonsFieldset", function () { var oButtonGroup = new ButtonGroup("mediaFilterButtons"); oButtonGroup.on("checkedButtonChange", onCheckedButtonChange); }); }()); </script> <div id="resultInfo"> <form id="button-example-form" name="button-example-form" method="post"> <fieldset id="mediaFilterButtonsFieldset"> <div id="mediaFilterButtons" class="yui-buttongroup ie7filter" style="z-index:11;"> <div id="mediaFilterLabel">Go to</div> <input id="radio1" class="filter_but" type="radio" name="0" value="First" checked rel="0" > <input id="radio2" class="filter_but" type="radio" name="2" value="Second" rel="2"> <input id="radio3" class="filter_but" type="radio" name="1" value="Third" rel="1"> </div> </fieldset> </form> </div> These are my YUI buttons. They're just 3 radio buttons turned into "buttons"--literally. My question is this: After people click the third button, I cannot manually check the first button anymore. How can I manually check "radio1"? I tried JQuery: $("#radio1").attr("checked",true); But this didn't work. The third button still remained pressed down.

  • jQuery $.ajax Not Working in IE8 but it works on FireFox & Chrome

    - by Sam3k
    I have the following ajax call which works perfectly in Firefox and Chrome but not IE: function getAJAXdates( startDate, numberOfNights, opts ) { var month = startDate.getMonth() + 1; var day = startDate.getDate(); var year = startDate.getFullYear(); var d = new Date(); var randNum = Math.floor(Math.random()*100000000); $.ajax({ type : "GET", dataType : "json", url : "/availability/ajax/bookings?rand="+randNum, cache : false, data : 'month='+month+'&day='+day+'&year='+year+'&nights='+numberOfNights, contentType : 'application/json; charset=utf8', success : function(data) { console.log('@data: '+data); insertCellData(data, opts, startDate); }, error:function(xhr, status, errorThrown) { console.log('@Error: '+errorThrown); console.log('@Status: '+status); console.log('@Status Text: '+xhr.statusText); } }); } I know for a fact that all the variables are passing the right content and $.ajax is indeed passing all the paramater/values. This is what I get on error: LOG: @Error: undefined LOG: @Status: parsererror LOG: @Status Text: OK I'm aware of the cache issue on IE and implemented a random paramater to clear it up. Finally these are the headers that are sent back from the backend: header('Content-Type: application/json; charset=utf8'); header("Cache-Control: no-cache"); header("Expires: 0"); header('Access-Control-Max-Age: 3628800'); header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE');

  • HTML 5 Video OnEnded Event not Firing

    - by Eric J.
    I'm trying to react to the HTML 5 onended event for the video tag without success. In the code snippet below I added the mouseleave event to be sure the jQuery code is correct and that event does activate the alert() box. The video plays just fine but onended does not cause my alert() to fire off. Testing in Chrome, updated today to version 5.0.375.55. <html> <head> <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script> <script> $(document).ready(function(){ $("#myVideoTag").bind('mouseleave onended', function(){ alert("All done, function!"); }); }); </script> </head> <body> <video id="myVideoTag" width="640" height="360" poster="Fractal-zoom-1-04-Snowflake.jpg" controls> <source src="Fractal-zoom-1-04-Snowflake.mp4" type="video/mp4"></source> <source src="Fractal-zoom-1-04-Snowflake.ogg" type="video/ogg"></source> </video> <body> <html>

  • Thread-safe data structures

    - by Inso Reiges
    Hello, I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call. After i implemented this it became apparent, that what i really need is atomicity across several API calls. For example if a caller needs to check the existence of an element before trying to insert it he can't do that atomically even if each single API call is atomic: if(!data_structure.exists(element)) { data_structure.insert(element); } The example is somewhat awkward, but the basic point is that we can't trust the result of exists call anymore after we return from atomic context (the generated assembly clearly shows a minor chance of context switch between the two calls). What i currently have in mind to solve this is exposing the lock through the data structure's public API. This way clients will have to explicitly lock things, but at least they won't have to create their own locks. Is there a better commonly-known solution to these kinds of problems? And as long as we're at it, can you advise some good literature on thread-safe design? Thank you.

  • JQuery Validate: only takes the last addMethod?

    - by Neuquino
    Hi, I need to add multiple custom validations to one form. I have 2 definitions of addMethod. But it only takes the last one... here is the code. $(document).ready(function() { $.validator.addMethod("badSelectionB",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_B_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $.validator.addMethod("badSelectionA",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_A_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $("#inscripcionForm").validate( { rules : { nombre : "required", apellido : "required", dni : { required: true, digits: true, }, mail : { required : true, email : true, }, comision_A_6: { badSelectionA:true, }, comision_B_6: { badSelectionB: true, } }, messages : { nombre : "Ingrese su nombre.", apellido : "Ingrese su apellido.", dni : { required: "Ingrese su dni.", digits: "Ingrese solo números.", }, mail : { required : "Ingrese su correo electrónico.", email: "El correo electrónico ingresado no es válido." } }, }); }); Do you have any clue of what is happening?

  • POST from edit/create partial views loaded into Twitter Bootstrap modal

    - by mare
    I'm struggling with AJAX POST from the form that was loaded into Twitter Bootstrap modal dialog. Partial view form goes like this: @using (Html.BeginForm()) { // fields // ... // submit <input type="submit" value="@ButtonsRes.button_save" /> } Now this is being used in non AJAX editing with classic postbacks. Is it possible to use the same partial for AJAX functionality? Or should I abstract away the inputs into it's own partial view? Like this: @using (Ajax.BeginForm()) { @Html.Partial("~/Views/Shared/ImageEditInputs.cshtml") // but what to do with this one then? <input type="submit" value="@ButtonsRes.button_save" /> } I know how to load this into Bootstrap modal but few changes should be done on the fly: the buttons in Bootstrap modal should be placed in a special container (the modal footer), the AJAX POST should be done when clicking Save which would first, validate the form and keep the modal opened if not valid (display the errors of course) second, post and close the modal if everything went fine in the view that opened the modal, display some feedback information at the top that save was succesful. I'm mostly struggling where to put what JS code. So far I have this within the List view, which wires up the modals: $(document).ready(function () { $('.openModalDialog').click(function (event) { event.preventDefault(); var url = $(this).attr('href'); $.get(url, function (data) { $('#modalContent').html(data); $('#modal').modal('show'); }); }); }); The above code, however, doesn't take into the account the special Bootstrap modal content placeholder (header, content, footer). Is it possible to achieve what I want without having multiple partial views with the same inputs but different @using and without having to do hacks with moving the Submit button around?

  • Why does Internet Explorer break "pegman" display in Google Maps API v3?

    - by Chad
    On my site here, the SteetView control, aka "Pegman", works great under Firefox. Under IE (7 in this case, but tested on 8 as well - same result) it breaks the display of the pegman control. Here's my map code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; directionsDisplay = new google.maps.DirectionsRenderer(); var milBase = new google.maps.LatLng(35.79648921414565, 139.40663874149323); var mapOpts = { streetViewControl: true, zoom: 12, center: milBase, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU }, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map($("#dirMap").get(0), mapOpts); directionsDisplay.setMap(map); var basePoly = new google.maps.Polygon({ paths: [new google.maps.LatLng(35.724496338474104, 139.3444061279297), new google.maps.LatLng(35.74748750802863, 139.3363380432129), new google.maps.LatLng(35.75765724051559, 139.34303283691406), new google.maps.LatLng(35.76545779822543, 139.3418312072754), new google.maps.LatLng(35.767547103447725, 139.3476676940918), new google.maps.LatLng(35.75835374997911, 139.34955596923828), new google.maps.LatLng(35.755149755962755, 139.3567657470703), new google.maps.LatLng(35.74679090345495, 139.35796737670898), new google.maps.LatLng(35.74762682821177, 139.36294555664062), new google.maps.LatLng(35.744422402303826, 139.36346054077148), new google.maps.LatLng(35.74860206266584, 139.36946868896484), new google.maps.LatLng(35.735644401200986, 139.36843872070312), new google.maps.LatLng(35.73843117306677, 139.36174392700195), new google.maps.LatLng(35.73592308277646, 139.3531608581543), new google.maps.LatLng(35.72686543236113, 139.35298919677734), new google.maps.LatLng(35.724496338474104, 139.3444061279297)], strokeColor: "#ff0000", strokeOpacity: 0.8, strokeWeight: 2, fillColor: "#FF0000", fillOpacity: 0.35 }); basePoly.setMap(map); var marker = new google.maps.Marker({ position: new google.maps.LatLng(35.79648921414565, 139.40663874149323), map: map, title: "Ruby International" }); function calcRoute() { var start = new google.maps.LatLng(35.74005964772476, 139.37083393335342); var end = new google.maps.LatLng(35.79648921414565, 139.40663874149323); var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } }); } The only real difference from my code and Google's code is that I use jQuery's document ready function instead of the body onload event to initialize my map. Can't imagine that's the cause though (works in v2 of the maps). Have I found a bug or is there something wrong in my code? Thanks in advance!

  • Interpolation and Morphing of an image in labview and/or openCV

    - by Marc
    I am working on an image manipulation problem. I have an overhead projector that projects onto a screen, and I have a camera that takes pictures of that. I can establish a 1:1 correspondence between a subset of projector coordinates and a subset of camera pixels by projecting dots on the screen and finding the centers of mass of the resulting regions on the camera. I thus have a map proj_x, proj_y <-- cam_x, cam_y for scattered point pairs My original plan was to regularize this map using the Mathscript function griddata. This would work fine in MATLAB, as follows [pgridx, pgridy] = meshgrid(allprojxpts, allprojypts) fitcx = griddata (proj_x, proj_y, cam_x, pgridx, pgridy); fitcy = griddata (proj_x, proj_y, cam_y, pgridx, pgridy); and the reverse for the camera to projector mapping Unfortunately, this code causes Labview to run out of memory on the meshgrid step (the camera is 5 megapixels, which apparently is too much for labview to handle) I then started looking through openCV, and found the cvRemap function. Unfortunately, this function takes as its starting point a regularized pixel-pixel map like the one I was trying to generate above. However, it made me hope that functions for creating such a map might be available in openCV. I couldn't find it in the openCV 1.0 API (I am stuck with 1.0 for legacy reasons), but I was hoping it's there or that someone has an easy trick. So my question is one of the following 1) How can I interpolate from scattered points to a grid in openCV; (i.e., given z = f(x,y) for scattered values of x and y, how to fill an image with f(im_x, im_y) ? 2) How can I perform an image transform that maps image 1 to image 2, given that I know a scattered mapping of points in coordinate system 1 to coordinate system 2. This could be implemented either in Labview or OpenCV. Note: I am tagging this post delaunay, because that's one method of doing a scattered interpolation, but the better tag would be "scattered interpolation"

  • jQuery urlencode/decode patch help

    - by jeerose
    Hi Gang, I'm using this jQuery urlencode and urldecode plugin - very simple and easy to use but it doesn't, in its original form, remove + from the string. The one comment on the home page suggests a patch but I don't know how to implement it. Can anyone help me out? The Page: http://www.digitalbart.com/jquery-and-urlencode/ //URL Encode/Decode $.extend({URLEncode:function(c){var o='';var x=0;c=c.toString(); var r=/(^[a-zA-Z0-9_.]*)/; while(x<c.length){var m=r.exec(c.substr(x)); if(m!=null && m.length>1 && m[1]!=''){o+=m[1];x+=m[1].length; }else{if(c[x]==' ')o+='+';else{var d=c.charCodeAt(x);var h=d.toString(16); o+='%'+(h.length<2?'0':'')+h.toUpperCase();}x++;}}return o;}, URLDecode:function(s){var o=s;var binVal,t;var r=/(%[^%]{2})/; while((m=r.exec(o))!=null && m.length>1 && m[1]!=''){ b=parseInt(m[1].substr(1),16); t=String.fromCharCode(b);o=o.replace(m[1],t);}return o;} }); The proposed Patch: function dummy_url_decode(url) { // fixed -- + char decodes to space char var o = url; var binVal, t, b; var r = /(%[^%]{2}|\+)/; while ((m = r.exec(o)) != null && m.length > 1 && m[1] != '') { if (m[1] == '+') { t = ' '; } else { b = parseInt(m[1].substr(1), 16); t = String.fromCharCode(b); } o = o.replace(m[1], t); } return o; } Thanks!

  • WCF deadlock when using callback channel

    - by mafutrct
    This is probably a simple mistake, but I could not figure out what was wrong. I basically got a method like this: [ServiceBehavior ( ConcurrencyMode = ConcurrencyMode.Reentrant, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true) ] public class Impl : SomeContract { public string Foo() { _CallbackChannel.Blah(); return ""; } } Its interface is decorated: [ServiceContract ( Namespace = "http://MyServiceInterface", SessionMode = SessionMode.Required, CallbackContract = typeof (WcfCallbackContract)) ] public interface SomeContract { [OperationContract] string Foo (); } The service is hosted like this: ServiceHost host = new ServiceHost (typeof (Impl)); var binding = new NetTcpBinding (); var address = new Uri ("net.tcp://localhost:8000/"); host.AddServiceEndpoint ( typeof (SomeContract), binding, address); host.Open (); The client implements the callback interface and calls Foo. Foo runs, calls the callback method and returns. However, the client is still struck in the call to Foo and never returns. The client callback method is never run. I guess I made a design mistake somewhere. If needed, I can post more code. Any help is appreciated.

  • Object oriented design suggestion

    - by pocoa
    Here is my code: class Soldier { public: Soldier(const string &name, const Gun &gun); string getName(); private: Gun gun; string name; }; class Gun { public: void fire(); void load(int bullets); int getBullets(); private: int bullets; } I need to call all the member functiosn of Gun over a Soldier object. Something like: soldier.gun.fire(); or soldier.getGun().load(15); So which one is a better design? Hiding the gun object as a private member and access it with getGun() function. Or making it a public member? Or I can encapsulate all these functions would make the implementation harder: soldier.loadGun(15); // calls Gun.load() soldier.fire(); // calls Gun.fire() So which one do you think is the best?

  • 2 jQuery plugins don't seem to work together

    - by Carbonara
    I have 2 plugins, amongst several others, that are loaded together. All of them work together correctly expect 2. By commenting out bits of code etc I've narrowed it down to the two plugins. These are the 2 plugins in question jQuery Tools tabs and NewsTicker I have tried calling them as follows as per their instructions $(document).ready(function(){ $().newsTicker({ newsList: "#news", startDelay: 10, placeHolder1: " []" }); $("ul.tabs").tabs("div.panes > div"); }); With the calls this way around the ticker works but the tabs do not. If I swap the calls round then the tabs work but the ticker does not. Both plugins work if the other call is commented out. Any ideas what could be wrong here or could something in the code of one of the plugins be affecting the other. Both plugins work ok when several other plugins are also called in the same script. I'm just wondering if I'm calling them in the wrong way or something being fairly new to jQuery

  • jquery Plugins/Validation using submitHandler

    - by Eyla
    Greeting, I'm using jquery Plugins/Validation library. I want to allow validation on submitting but I'm not sure where I should insert the code: I know that I can user submitHandler for that but after reading the document I had hard time to implement it so I need your help guys. jquery validation is working ok but the problem that the form still submitted even there are invalid inputs. here is my validation function and I want to know how can I make it to not submit the form if there is invalid input. by the way, I'm using asp.net button for submitting the form. here is my code: $(document).ready(function() { $("#aspnetForm").validate({ rules: { "<%=txtHomePhone.UniqueID %>": { phonehome: true }, "<%=txtMobileHome.UniqueID %>": { mobilephone: true }, "<%=txtFaxHome.UniqueID %>": { faxhome: true }, "<%=txtEmailHome.UniqueID %>": { email: true }, "<%=txtZipCodeHome.UniqueID %>": { ziphome: true }, //work "<%=txtPhonework.UniqueID %>": { phonework: true }, "<%=txtMobileWork.UniqueID %>": { mobilework: true }, "<%=txtFaxWork.UniqueID %>": { faxwork: true }, "<%=txtEmailWork.UniqueID %>": { email: true }, "<%=txtWebSite.UniqueID %>": { url: true }, "<%=txtZipWork.UniqueID %>": { zipwork: true } }, errorElement: "mydiv", wrapper: "mydiv", // a wrapper around the error message errorPlacement: function(error, element) { offset = element.offset(); error.insertBefore(element) error.addClass('message'); // add a class to the wrapper error.css('position', 'absolute'); error.css('left', offset.left + element.outerWidth()); error.css('top', offset.top - (element.height() / 2)); } });

  • Force Postback from code behind? Or reload JavaScript from an Asynchronous Postback?

    - by sah302
    Hi all, I've got a Jquery UI dialog that pops up to confirm the creation of an item after filling out a form. I have the form in an update panel due to various needs of the form, and especially because I want validation being done on the form without reloading the page. JavaScript appears to not reload on an asynchronoous postback. This means when the form is a success and I change the variable 'formSubmitPass' to true, it does not get passed to the Javascript via <%= formSubmitPass %. If I add a trigger to the submit button to do a full postback, it works. However I don't want the submit button to do a full postback as I said so I can validate the form within the update panel. How can I have this so my form validates asynchronously, but my javaScript will properly reload when the form is completed successfully and the item is saved to the database? Javascript: var formSubmitPass = '<%= formSubmitPass %>'; var redirectUrl = '<%= redirectUrl %>'; function pageLoad() { $('#formPassBox').dialog({ autoOpen: false, width: 400, resizable: false, modal: true, draggable: false, buttons: { "Ok": function() { window.location.href = redirectUrl; } }, open: function(event, ui) { $(".ui-dialog-titlebar-close").hide(); var t = window.setTimeout("goToUrl()", 5000); } }); if(formSubmitPass == 'True') { $('#formPassBox').dialog({ autoOpen: true }); } So how can I force a postback from the code behind, or reload the JavaScript on an Asynchronous Postback, or do this in a way that will work such that I can continue to do Async form validation? Edit: I change formSubmitPass at the very end of the code behind: If errorCount = 0 Then formSubmitPass = True upForm.Update() Else formSubmitPass = False End If So on a full postback, the value does change.

  • How To Create Your Own x86 Operating System for Modern PC Computers

    I'd like to create a new operating system for x86 PC computers. I'd like it to be 64-bit but possibly run as 32-bit as well. I have these kinds of questions: What kinds of things do you start working on first? Knowing where to start in writing your own operating system seems to me to be a tricky subject, so I am interested in your input. Generally how to go about making your own 32-bit/64-bit operating system, or good resources that mention useful information about going about writing your own operating system for x86 computers. I don't care how old sources are as long as they are still relevant and useful to what I am doing. I know that I will want it to have kernel drivers that access peripheral hardware directly. Where should I look for advice and documentation for programming and understanding the interface to peripheral hardware the operating system will communicate with? I will need to understand how the operating system will receive input and interact with keyboards, mice, computer monitors, hard drives, USB, etc. etc. This is probably the area I know least about. I have the Intel instruction set manuals and have been getting more familiar with assembly programming, so the CPU side of things is what I know the most about. At this point I'm thinking that I'd like to implement the Linux system calls within my operating system so that programs that run on Linux can run on my operating system. I want my operating system to use the ELF binary format. I wonder what obstacles I have to overcome to achieve this Linux compatibility. Are the main things implementing the system calls that Linux provides, and using the ELF format? What else? I am also interested in people's thoughts about why it might not be a good idea to make your own operating system, and why it is a good idea to make your own operating system. Thank you for any input.

  • how to get all group images in facebook using FACEBOOK API

    - by From.ME.to.YOU
    Hello i'm trying to get all the images from a facebook group using facebook API i have a problem i can't get all the photos using $facebook->api_client->call_method('Photos.get', array('subj_id' => $uid)); http://wiki.developers.facebook.com/index.php/Photos.get what i'm using now is the method $albums = $facebook->api_client->photos_getAlbums($uid, NULL); http://wiki.developers.facebook.com/index.php/Photos.getAlbums and then loop for ever album on $facebook->api_client->call_method('Photos.get', array('subj_id' => $uid)); then i add every new array results to my big array $big_array = array_merge($big_array,$result_array_from_that_call); 2 problems occurs here : 1- sometimes this calls fails - i think because of too many calls per second - 2- the request takes a v.long time to process is there a better way to do that? Thanks guys Cheers EDIT :: i tried to get all the images using $facebook->api_client->call_method('Photos.get', array('subj_id' => $uid)); and using $uid as the group ID but that's doesn't work " don't know why maybe because all the images is listed in groups "

  • fortran 90 user defined type, passing by value ?

    - by user279137
    I have an issue in fortran 90. I have a user defined type and when I call one of the MPI subroutines the data looks to be passed by values (not address, as I thought it should). The output arguments aren't modified. It seems to be specific to the MPI calls I tried the same thing in a simple test, and I can change the passed in values in the calling scope. I'm not sure why this is because I thought fortran always pass by address. Any idea what could be going on? Just to be clear the commented snippet shows how the calls are made. The in the first call, c%NSubDomains, is an output argument and should be modified in the calling scope, but its not. WHen I call with an array rather than a member of user defined type it works, in the uncommented snippet. ! ! This doesn't work output values aren't modified ?? ! call MPI_Dims_create(c%NProcs,c%NDims,c%NSubDomains,iErr) nsubs(:)=0 call MPI_Dims_create(c%NProcs,c%NDims,nsubs,iErr) c%NSubDomains=nsubs Thanks

  • jQuery modal Dialog over iFrame

    - by Ram
    I am using jQuery UI dialog for modal popups. I have some iframes in my page as well. The iFrame (z-Index = 1500) sits on top of the parent page (z-index =1000). I open the modal dialog from the parent page. I am trying to set the z-index using $('modal').dialog('option','zIndex',3000); but this is not working. I also tried stack:true (to stack it on top), and .dialog( 'moveToTop' ) as well, but they don't seem to work. Here is the code: Parent page: using style sheet : from "css/ui-darkness/jquery-ui-1.7.2.custom.css" using scripts: jquery-1.3.2.min.js && jquery-ui-1.7.2.custom.min.js <script type="text/javascript" language="javascript"> function TestModal() { var modal = "<div id='modal'>Hello popup world</div>"; $(modal).dialog({ modal: true, title: 'Modal Popup', zIndex: 12000, // settin it here works, but I want to set it at runtime instead of setting it at design time close: function() { setTimeout(TestModal, 5000); $(this).remove(); } }); $('modal').dialog('option', 'zIndex', 11000); // these dont work $('modal').dialog('moveToTop'); // these dont work $('modal').dialog('option', 'stack', true); // these dont work } /** Run with defaults **/ $(document).ready(function() { TestModal(); }); </script> <div> Hello World <br /> </div> <iframe src="blocker.htm" width="100%" height="100%" frameborder="0" scrolling="no" name="myInlineFrame" style="z-index:10000;background-color:Gray;position:absolute;top:0px;left:0px" ALLOWTRANSPARENCY="false"> </iframe> iframe : blocker.htm .wrap{width:100%;height:100%} I am an iframe and I am evil
