  • XAML ComboBox SelectionChanged Fires OnLoad

    - by griegs
    If I have a ComboBox that has a SelectionChanged event, it fires when I'm loading the control. So at page load I set the SelectedValue and the SelectionChanged event fires which is not what I want to happen. What is the accepted apporach to stopping this?

  • jQuery Cycle plugin IE6/7 issues

    - by Aaron Moodie
    I've implemented a slideshow using the Cycle plugin, which is working in all browsers except IE6&7, where the images just show up in a list, and the #page_copy div is not hiding. I've been going through the code all day without any luck, and not exactly sure how or what I should be looking for. What would be the best way to go about debugging this issue? I know that the #page_copy div is hiding when I remove the rest of the code, and I've tried the reverse (which had no result) <script type="text/javascript" charset="utf-8"> jQuery.fn.fadeToggle = function(speed, easing, callback) { return this.animate({opacity: 'toggle'}, speed, easing, callback); }; $(document).ready(function() { $('#page_copy').hide(); $('a#info_close_button').click(function() { $('#page_copy').fadeOut(200); return false; }); $('a#info_button').click(function() { $('#page_copy').fadeToggle(200); return false; }); }); $(window).load(function() { // vertically center single image var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } }); // wait until images have loaded before starting cycle $(window).load(function() { // front image rotator $('#images').cycle({ fx: 'fade', speed: 300, next: '.next', prev: '.prev', containerResize: 0, timeout: 0, delay: -2000, before: onBefore }); }); // hide all but the first image when page loads $(document).ready(function() { $('#images img:gt(0)').hide(); }); // callback fired when each slide transition begins function onBefore(curr,next,opts) { var $slide = $(next); var w = $slide.width(); var h = $slide.height(); $slide.css({ marginTop: (620 - h) / 2, marginLeft: (650 - w) / 2 }); }; </script>

  • jQuery ajax() returning json object to another function on success causes error

    - by Michael Mao
    Hi all: I got stuck in this problem for an hour. I am thinking this is something relates to variable scoping ? Anyway, here is the code : function loadRoutes(from_city) { $.ajax( { url: './ajax/loadRoutes.php', async : true, cache : false, timeout : 10000, type : "POST", dataType: 'json', data : { "from_city" : from_city }, error : function(data) { console.log('error occured when trying to load routes'); }, success : function(data) { console.log('routes loaded successfully.'); $('#upperright').html(""); //reset upperright box to display nothing. return data; //this line ruins all //this section works just fine. $.each(data.feedback, function(i, route) { console.log("route no. :" + i + " to_city : " + route.to_city + " price :" + route.price); doSomethingHere(i); }); } }); } The for each section works just fine inside the success callback region. I can see Firebug console outputs the route ids with no problem at all. For decoupling purpose, I reckon it would be better to just return the data object, which in JSON format, to a variable in the caller function, like this: //ajax load function function findFromCity(continent, x, y) { console.log("clicked on " + continent + ' ' + x + ',' + y); $.ajax( { url: './ajax/findFromCity.php', async : true, cache : false, timeout : 10000, type : "POST", dataType : 'json', data : { "continent" : continent, "x" : x, "y" : y }, error : function(data) { console.log('error occured when trying to find the from city'); }, success : function(data) { var cityname = data.from_city; //only query database if cityname was found if(cityname != 'undefined' && cityname != 'nowhere') { console.log('from city found : ' + cityname); data = loadRoutes(cityname); console.log(data); } } }); } Then all of a sudden, everything stops working! Firebug console reports data object as "undefined"... hasn't that being assigned by the returning object from the method loadRoutes(cityname)? Sorry my overall knowledge on javascript is quite limited, so now I am just like a "copycat" to work on my code in an amateur way.

  • Flash -> ByteArray -> AMFPHP -> Invalid Image !??

    - by undefined
    Hi, Im loading images into Flash and using JPGEncoder to encode the image to a ByteArray and send this to AMF PHP which writes out the bytearray to a file. This all appears to work correctly and I can download the resulting file in Photoshop CS4 absolutely fine. When i try to open it from the desktop or open it back in Flash it doesnt work... Picasa my default image browser says "Invalid" Here is the code i use to write the bytearray to a file - $jpg = $GLOBALS["HTTP_RAW_POST_DATA"]; file_put_contents($filename, $jpg); That's it ... I use the NetConnection class to connect and call the service, do I need to say Im sending jpg data? I assumed that JPGEncoder took care of that. How can I validate the bytearray before writing the file? Do I need to set MIME type or something .. excuse the slightly noob questions, a little knowledge can be a dangerous thing. Thanks --------------------------------------- PART II ------------------------------------------ Here is some code - 1) load the image into Flash player item.load(); function _onImageDataLoaded(evt:Event):void { var tmpFileRef:FileReference=FileReference(evt.target); image_loader=new Loader ; image_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, _onImageLoaded); image_loader.loadBytes(tmpFileRef.data); } function _onImageLoaded(evt:Event):void { bitmap=Bitmap(evt.target.content); bitmap.smoothing=true; if (bitmap.width>MAX_WIDTH||bitmap.height>MAX_HEIGHT) { resizeBitmap(bitmap); } uploadResizedImage(bitmap); } function resizeBitmap(target:Bitmap):void { if (target.height>target.width) { target.width=MAX_WIDTH; target.scaleY=target.scaleX; } else if (target.width >= target.height) { target.height=MAX_HEIGHT; target.scaleX=target.scaleY; } } function uploadResizedImage(target:Bitmap):void { var _bmd:BitmapData=new BitmapData(target.width,target.height); _bmd.draw(target, new Matrix(target.scaleX, 0, 0, target.scaleY)); var encoded_jpg:JPGEncoder=new JPGEncoder(90); var jpg_binary:ByteArray=encoded_jpg.encode(_bmd); _uploadService=new NetConnection(); _uploadService.objectEncoding=ObjectEncoding.AMF3 _uploadService.connect("http://.../amfphp/gateway.php"); _uploadService.call("UploadService.receiveByteArray",new Responder(success, error), jpg_binary, currentImageFilename); } Many thanks for you help

  • Youtube video processing on iPhone

    - by Chonch
    Hey In my iPhone app, I want to load a video from youtube, perform some basic image processing on it and display it to the user. I am using openCV to do my image processing, and I know I can use it for grabbing all of the frames from the video as well (cvRetrieveFrame). My only problem is that cvRetrieveFrame expects to get its source of type CvCapture* which can be created either by a camera source or by a file name. How can I set a youtube video file as the source for CvCapture*? Thanks,

  • Cache the result of a MySQLdb database query in memory

    - by ensnare
    Our application fetches the correct database server from a pool of database servers. So each query is really 2 queries, and they look like this: Fetch the correct DB server Execute the query We do this so we can take DB servers online and offline as necessary, as well as for load-balancing. But the first query seems like it could be cached to memory, so it only actually queries the database every 5 or 10 minutes or so. What's the best way to do this? Thanks.

  • Loading, listing, and using R Modules and Functions in PL/R

    - by Dave Jarvis
    I am having difficulty with: Listing the R packages and functions available to PostgreSQL. Installing a package (such as Kendall) for use with PL/R Calling an R function within PostgreSQL Listing Available R Packages Q.1. How do you find out what R modules have been loaded? SELECT * FROM r_typenames(); That shows the types that are available, but what about checking if Kendall( X, Y ) is loaded? For example, the documentation shows: CREATE TABLE plr_modules ( modseq int4, modsrc text ); That seems to allow inserting records to dictate that Kendall is to be loaded, but the following code doesn't explain, syntactically, how to ensure that it gets loaded: INSERT INTO plr_modules VALUES (0, 'pg.test.module.load <-function(msg) {print(msg)}'); Q.2. What would the above line look like if you were trying to load Kendall? Q.3. Is it applicable? Installing R Packages Using the "synaptic" package manager the following packages have been installed: r-base r-base-core r-base-dev r-base-html r-base-latex r-cran-acepack r-cran-boot r-cran-car r-cran-chron r-cran-cluster r-cran-codetools r-cran-design r-cran-foreign r-cran-hmisc r-cran-kernsmooth r-cran-lattice r-cran-matrix r-cran-mgcv r-cran-nlme r-cran-quadprog r-cran-robustbase r-cran-rpart r-cran-survival r-cran-vr r-recommended Q.4. How do I know if Kendall is in there? Q.5. If it isn't, how do I find out what package it is in? Q.6. If it isn't in a package suitable for installing with apt-get (aptitude, synaptic, dpkg, what have you), how do I go about installing it on Ubuntu? Q.7. Where are the installation steps documented? Calling R Functions I have the following code: EXECUTE 'SELECT ' 'regr_slope( amount, year_taken ),' 'regr_intercept( amount, year_taken ),' 'corr( amount, year_taken ),' 'sum( measurements ) AS total_measurements ' 'FROM temp_regression' INTO STRICT slope, intercept, correlation, total_measurements; This code calls the PostgreSQL function corr to calculate Pearson's correlation over the data. Ideally, I'd like to do the following (by switching corr for plr_kendall): EXECUTE 'SELECT ' 'regr_slope( amount, year_taken ),' 'regr_intercept( amount, year_taken ),' 'plr_kendall( amount, year_taken ),' 'sum( measurements ) AS total_measurements ' 'FROM temp_regression' INTO STRICT slope, intercept, correlation, total_measurements; Q.8. Do I have to write plr_kendall myself? Q.9. Where can I find a simple example that walks through: Loading an R module into PG. Writing a PG wrapper for the desired R function. Calling the PG wrapper from a SELECT. For example, would the last two steps look like: create or replace function plr_kendall( _float8, _float8 ) returns float as ' agg_kendall(arg1, arg2) ' language 'plr'; CREATE AGGREGATE agg_kendall ( sfunc = plr_array_accum, basetype = float8, -- ??? stype = _float8, -- ??? finalfunc = plr_kendall ); And then the SELECT as above? Thank you!

  • Django + FastCGI - randomly raising OperationalError

    - by ibz
    I'm running a Django application. Had it under Apache + mod_python before, and it was all OK. Switched to Lighttpd + FastCGI. Now I randomly get the following exception (neither the place nor the time where it appears seem to be predictable). Since it's random, and it appears only after switching to FastCGI, I assume it has something to do with some settings. Found a few results when googleing, but they seem to be related to setting maxrequests=1. However, I use the default, which is 0. Any ideas where to look for? PS. I'm using PostgreSQL. Might be related to that as well, since the exception appears when making a database query. Thanks.

  • Manually parse string as XAML Attribute

    - by bitbonk
    How does the XAML Parser convert the string "Red" in Foreground="Red" to a SolidColorBrush? Allthough I know the Types have System.ComponentModel.TypeConverter defined, I doupt that the WPF XAML parser acutally always uses those to convert the string to the brush. Are there any XAML APIs apart from XamlReader.Load (wich wants a valid xml string) that I could use to parse a single string as if it where an attibute for a certain property?

  • Loading a Page into a jQuery Dialog

    - by Dave
    I tend to follow a fairly "modular" approach to building applications and I recently started working with jQuery. The application I'm working on is going to be fairly large so I'm trying to break pieces out into separate files/modules when possible. One example of this is a "User Settings" dialog. This dialog has a form, a few tabs, and quite a good number of input fields so I want to develop it in a separate HTML file (PHP actually, but it can be considered HTML for the purposes of this example). It's an entire page in and of itself with all the tags you would expect such as: <html><head></head><body></body></html> So I can now develop, what I want to be, the dialog separate from the base application. This dialog has it's own Javascript (A LOT of Javascript, in fact) in the head as well, with jQuery $(document).ready(){} capturing, etc. Everything works flawlessly in isolation. However, when I attempt to load the jQuery modal dialog with the page (inside of the main application page), as one might expect, trouble ensues. Here's a brief, very simple, example of what it looks like: editUserDialog.load ("editUser.php", {id : $('#userList').val(), popup : "true"}, function () { editUserDialog.dialog ("option", "title" , "Edit User"); editUserDialog.dialog ('open'); }); (I'm passing in a "popup" flag to the page so that the page can determine its context -- i.e. as a page or inside of the jQuery dialog). Question 1: When I moved the code from the "head" into "body" (in the editUser.php page) it actually worked for the most part. It seemed that jQuery was calling the $(document).ready() function in the context of the body of the loaded file and not the head. Is this a bad idea? Question 2: Is my process for building this application just totally flawed to begin with? I've scoured the net to attempt to find a "best practices" sort of document to building reasonably large applications using jQuery/PHP without a lot of success so maybe there's something out there someone else is aware of that I've somehow missed. Thanks for bearing with me while I attempt to describe the issues I've encountered and I hope I've accurately described the problem.

  • Brief white screen when loading PHP page?

    - by orbit82
    What would cause a brief flash of white screen while a PHP page is loading? I just noticed it today on a WordPress theme that I am building and am wondering if this is a cause for concern. As a page loads, the screen will flash white before showing the page content. Sometimes this happens on every single page load, other times it only happens intermittently.

  • TVirtualStringTree - resetting non-visual nodes and memory consumption

    - by Remy Lebeau - TeamB
    I have an app that loads records from a binary log file and displays them in a virtual TListView. There are potentially millions of records in a file, and the display can be filtered by the user, so I do not load all of the records in memory at one time, and the ListView item indexes are not a 1-to-1 relation with the file record offsets (List item 1 may be file record 100, for instance). I use the ListView's OnDataHint event to load records for just the items the ListView is actually interested in. As the user scrolls around, the range specified by OnDataHint changes, allowing me to free records that are not in the new range, and allocate new records as needed. This works fine, speed is tolerable, and the memory footprint is very low. I am currently evaluating TVirtualStringTree as a replacement for the TListView, mainly because I want to add the ability to expand/collapse records that span multiple lines (I can fudge it with the TListView by incrementing/decrementing the item count dynamically, but this is not as straight forward as using a real tree). For the most part, I have been able to port the TListView logic and have everything work as I need. I notice that TVirtualStringTree's virtual paradigm is vastly different, though. It does not have the same kind of OnDataHint functionality that TListView does (I can use the OnScroll event to fake it, which allows my memory buffer logic to continue working), and I can use the OnInitializeNode event to associate nodes with records that are allocated. However, once a tree node is initialized, it sees that it remains initialized for the lifetime of the tree. That is not good for me. As the user scrolls around and I remove records from memory, I need to reset those non-visual nodes without removing them from the tree completely, or losing their expand/collapse states. When the user scrolls them back into view, I can re-allocate the records and re-initialize the nodes. Basically, I want to make TVirtualStringTree act as much like TListView as possible, as far as its virtualization is concerned. I have seen that TVirtualStringTree has a ResetNode() method, but I encounter various errors whenever I try to use it. I must be using it wrong. I also thought of just storing a data pointer inside each node to my record buffers, and I allocate and free memory, update those pointers accordingly. The end effect does not work so well, either. Worse, my largest test log file has ~5 million records in it. If I initialize the TVirtualStringTree with that many nodes at one time (when the log display is unfiltered), the tree's internal overhead for its nodes takes up a whopping 260MB of memory (without any records being allocated yet). Whereas with the TListView, loading the same log file and all the memory logic behind it, I can get away with using just a few MBs. Any ideas?

  • Index page in Magento is way too slow, what can I do?

    Weirdly, the index page of my magento commerce is very slow, while when you navigate the products, brands, searchs etc is very fast, but everytime you click on the banner to go for home or enter the website, it take ages to load I wonder what can I do about this? I don't know where to start, since I am new at magento. I thought I could go on and read the code, but that would take ages too, since magento is very big. Maybe I can analyze it somehow?

  • Set default form textfield value (webbrowser control/DOM Javscript)

    - by Khou
    Hi I would like my application to load a webpage and set default the form textfield value a predefine value. Requirements: -The application is a windows form, it is to use the web browser control, to load a web page. -Textfield values are define by within the application. -When textfield on the webpage matches the applications predefined elements, the predefine fixed value is set and can not be changed by the end user. Example If my application defines element "FirstName" equal to value "John", the text field for value for element "FirstName" will always equal "John" and this value can not be changed by the end user. Below is html/javascript code to perform this functionality, now how do I implement this in a windows form? (without having to modify the loaded webpage source code (if possible). HTML <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>page title</title> <script script type="text/javascript" src="demo1.js"></script> </head> <body onload="def(document.someform, 'name', 'my default name value');"> <h2 style="color: #8e9182">test form title</h2> <form name="someform" id="someform_frm" action="#"> <table cellspacing="1"> <tr><td><label for="name">NameX: </label></td><td><input type="text" size="30" maxlength="155" name="name" onchange="def(document.someform, 'name', 'my default name value');"></td></tr> <tr><td><label for="name2">NameY: </label></td><td><input type="text" size="30" maxlength="155" name="name2"></td></tr> <tr><td colspan="2"><input type="button" name="submit" value="Submit" onclick="showFormData(this.form);" ></td></table> </form> </body> </html> JAVASCRIPT function def(oForm, element_name, def_txt) { oForm.elements[element_name].value = def_txt; }

  • Ninject.Web.PageBase still resulting in null reference to injected dependency

    - by Ted
    I have an ASP.NET 3.5 WebForms application using Ninject 2.0. However, attempting to use the Ninject.Web extension to provide injection into System.Web.UI.Page, I'm getting a null reference to my injected dependency even though if I switch to using a service locator to provide the reference (using Ninject), there's no issue. My configuration (dumbed down for simplicity): public partial class Default : PageBase // which is Ninject.Web.PageBase { [Inject] public IClubRepository Repository { get; set; } protected void Page_Load(object sender, EventArgs e) { var something = Repository.GetById(1); // results in null reference exception. } } ... //global.asax.cs public class Global : Ninject.Web.NinjectHttpApplication { /// <summary> /// Creates a Ninject kernel that will be used to inject objects. /// </summary> /// <returns> /// The created kernel. /// </returns> protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); return kernel; } .. ... public class MyModule : NinjectModule { public override void Load() { Bind<IClubRepository>().To<ClubRepository>(); //... } } Getting the IClubRepository concrete instance via a service locator works fine (uses same "MyModule"). I.e. private readonly IClubRepository _repository = Core.Infrastructure.IoC.TypeResolver.Get<IClubRepository>(); What am I missing? [Update] Finally got back to this, and it works in Classic Pipeline mode, but not Integrated. Is the classic pipeline a requirement? [Update 2] Wiring up my OnePerRequestModule was the problem (which had removed in above example for clarity): protected override IKernel CreateKernel() { var module = new OnePerRequestModule(); module.Init(this); IKernel kernel = new StandardKernel(new MyModule()); return kernel; } ...needs to be: protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); var module = new OnePerRequestModule(); module.Init(this); return kernel; } Thus explaining why I was getting a null reference exception under integrated pipeline (to a Ninject injected dependency, or just a page load for a page inheriting from Ninject.Web.PageBase - whatever came first).
