  • UITableView Inactive Until Scroll iPhone

    - by dubbeat
    HI, I'm trying to find the cause of some annoying behaviour with my UITableView. In each cell of my table (10 of them ) I asynchronously load an image. The problem is, is that if I don't touch the app at all the imageviews will permanently show a loading icon. However as soon as I scroll a cell off the screen and back on again the image shows straight away. What could be causing this "stuck in the mud" behaviour? Is there a way to force whatever gets called when the list is scrolled to make the needed update happen? #define ASYNC_IMAGE_TAG 9999 #define LABEL_TAG 8888 // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { PromoListItem *promo = [promoList objectAtIndex:indexPath.row]; static NSString *CellIdentifier = @"Cell"; AsyncImageView *asyncImageView = nil; UILabel *label = nil; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; CGRect frame; frame.origin.x = 0; frame.origin.y = 0; frame.size.width = 100; frame.size.height = 100; asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease]; asyncImageView.tag = ASYNC_IMAGE_TAG; [cell.contentView addSubview:asyncImageView]; frame.origin.x = 110; frame.size.width =100; label = [[[UILabel alloc] initWithFrame:frame] autorelease]; label.tag = LABEL_TAG; [cell.contentView addSubview:label]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } else { asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG]; label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG]; } NSURL *url = [NSURL URLWithString:promo.imgurl]; [asyncImageView loadImageFromURL:url]; label.text = promo.artistname; return cell; }

  • Nothing gets displayed when debugging Microsoft Surface

    - by leftend
    I am trying to write my first Microsoft Surface application, and am doing the development on the Surface unit itself. I successfully re-created the quick "Photos" application that is shown on the PDC Video, however, now that I'm trying to create my own app - nothing actually shows up when I run it. I'm mainly just adding ScatterViews right now - and they show up fine in the designer, but as soon as I hit F5 - the shell is shown on the surface - but none of the ScatterViews show up. Here's my xaml code so far. Am I missing something?? <s:SurfaceWindow x:Class="SurfaceUITreeDemo.TreeDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="http://schemas.microsoft.com/surface/2008" Title="WYITT Tree Demo" AllowsTransparency="False" Background="Beige"> <s:SurfaceWindow.Resources> <ImageBrush x:Key="WindowBackground" Stretch="None" Opacity="0.6" ImageSource="pack://application:,,,/Resources/TreeDemoBackground.jpg"/> </s:SurfaceWindow.Resources> <Grid Background="{StaticResource WindowBackground}" > <s:ScatterView Name="test"> <Image Source="C:\dev\Network-Alt-icon.png"/> </s:ScatterView> <s:ScatterView Height="100" Margin="456,160,348,0" Name="scatterView1" VerticalAlignment="Top" Background="Black"> <s:ScatterViewItem Height="100" Width="150"> <Image Source="C:\dev\Network-Alt-icon.png"/> </s:ScatterViewItem> <s:ScatterViewItem></s:ScatterViewItem> ScatterView </s:ScatterView> </Grid> </s:SurfaceWindow>

  • DisplayObject snapshot in flex 3

    - by simplemagik
    i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas? The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"? <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.graphics.ImageSnapshot; private function SnapshotButtonHandler():void { var snapshot:ImageSnapshot = ImageSnapshot.captureImage(AppCanvas); var file:FileReference = new FileReference(); file.save(snapshot.data, "canvas.png"); } ]]> </mx:Script> <mx:Canvas id="AppCanvas" width="800" height="300" backgroundColor="0xFFFFFF"> <mx:Box x="750" y="100" width="100" height="100" backgroundColor="0xCCCCCC" /> </mx:Canvas> <mx:Button id="SnapshotButton" label="take snapshot" click="SnapshotButtonHandler()" /> </mx:Application>

  • Can I load a UIImage from a URL?

    - by progrmr
    I have a URL for an image (got it from UIImagePickerController) but I no longer have the image in memory (the URL was saved from a previous run of the app). Can I reload the UIImage from the URL again? I see that UIImage has a imageWithContentsOfFile: but I have a URL. Can I use NSData's dataWithContentsOfURL: to read the URL? EDIT based on @Daniel's answer I tried the following code but it doesn't work... NSLog(@"%s %@", __PRETTY_FUNCTION__, photoURL); if (photoURL) { NSURL* aURL = [NSURL URLWithString:photoURL]; NSData* data = [[NSData alloc] initWithContentsOfURL:aURL]; self.photoImage = [UIImage imageWithData:data]; [data release]; } When I ran it the console shows: -[PhotoBox willMoveToWindow:] file://localhost/Users/gary/Library/Application%20Support/iPhone%20Simulator/3.2/Media/DCIM/100APPLE/IMG_0004.JPG *** -[NSURL length]: unrecognized selector sent to instance 0x536fbe0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL length]: unrecognized selector sent to instance 0x536fbe0' Looking at the call stack, I'm calling URLWithString, which calls URLWithString:relativeToURL:, then initWithString:relativeToURL:, then _CFStringIsLegalURLString, then CFStringGetLength, then forwarding_prep_0, then forwarding, then -[NSObject doesNotRecognizeSelector]. Any ideas why my NSString (photoURL's address is 0x536fbe0) doesn't respond to length? Why does it say it doesn't respond to -[NSURL length]? Doesn't it know that param is an NSString, not a NSURL?

  • PHP DOMDocument Error Handling Problem

    - by Jon
    I'm having trouble trying to write an if statement for DOM that will check if $html is blank. However whenever the html page does end up blank, it just removes everything that would be below DOM (including what I had to check if it was blank). $html = file_get_contents("http://example.com/"); $dom = new DOMDocument; @$dom->loadHTML($html); $links = $dom->getElementById('dividhere')->getElementsByTagName('img'); foreach ($links as $link) { echo $link->getAttribute('src'); } All this does is grab an image url in the specified div, which works perfectly until the page is a blank html page. I've tried using SimpleHTMLDOM, which didn't work either (it didn't even fetch the image on working pages). Did I happen to miss something with this one or am I just missing something in both? include_once('simple_html_dom.php') $html = file_get_html("http://example.com/"); foreach($html->find('div[id="dividhere"]') as $div) { if(empty($div->src)) { continue; } echo $div->src; }

  • Amazon access key showing in URL for Carrierwave and Fog

    - by kcurtin
    I just switched from storing my images uploaded via Carrierwave locally to using Amazon s3 via the fog gem in my Rails 3.1 app. While images are being added, when I click on an image in my application, the URL is providing my access key and a signature. Here is a sample URL (XXX replaced the string with the info): https://s3.amazonaws.com/bucketname/uploads/photo/image/2/IMG_4842.jpg?AWSAccessKeyId=XXX&Signature=XXX%3D&Expires=1332093418 This is happening in development (localhost:3000) and when I am using heroku for production. Here is my uploader: class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick storage :fog def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end process :convert => :jpg process :resize_to_limit => [640, 640] version :thumb do process :convert => :jpg process :resize_to_fill => [280, 205] end version :avatar do process :convert => :jpg process :resize_to_fill => [120, 120] end end And my config/initializers/fog.rb : CarrierWave.configure do |config| config.fog_credentials = { :provider => 'AWS', :aws_access_key_id => 'XXX', :aws_secret_access_key => 'XXX', } config.fog_directory = 'bucketname' config.fog_public = false end Anyone know how to make sure this information isn't available?

  • internet explorer 7 iframe unloads when going back

    - by André
    Hi this is my first post here, so please be kind ;-) i'm implementing a browser history manager, just like rsh or yui browser history manager. The idea was not to constantly poll the url hash of a hidden iframe, but to capture the onscroll event of an iframe, when it scrolls to an anchor name on an urlhashchange. So on every click i add an new anchor to iframe and set the iframe's hash to the anchors name. When pressing the back or forward button the frame scrolls to the previous or next anchor and the onscroll event is fired. That works great on firefox 3.0+, IE6 and Opera but on IE7 when hiting the back button the frame unloads and loses all its anchors. If anyone has an idea why this is happening or even a fix for this "bug", please i'm slowly going insane over this. thanks in advance btw the onscroll idea comes from: http://www.zachleat.com/web/2008/08/21/onhashchange-without-setinterval/

  • Filtering custom fields on wordpress admin page

    - by Kyril
    I'm currently working on a wordpress 2.9.2 plugin (my first) that creates additional custom fields that will later be read from the template. The plugin adds an additional meta box to the "Edit Post" screen which is responsible for manipulating these values. My problem is that the custom fields generated by the plugin also show up in the "Custom Fields" box. Ideally I would like for the custom fields generated by the plugin to be managed separately from any other custom fields for that same post/page. Is there a way that I can filter fields specific to my plugin to prevent them from being displayed in the "Custom Fields" box? I have yet to locate any action or filter that will let me capture and manipulate those values before they are rendered on "Edit Post".

But i can configure the device to send the data over port 80. so we wrote a genericservlet to capture this data on GAE. But it is not obtaining any values from the client. any suggestions to fix this issue?

  • How do I ensure only the headers are shown for the first item in an ItemsControl in WPF?

    - by Dan Ryan
    I am using MVVM binding an ObservableCollection of children to an ItemsControl. The ItemsControl contains a UserControl used to style the UI for the children. <ItemsControl ItemsSource="{Binding Documents}"> <ItemsControl.ItemTemplate> <DataTemplate> <View:DocumentView Margin="0, 10, 0, 0" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I want to show a header row for the contents of the ItemsControl but only want to show this once at the top (not for every child). How can I implement this behaviour in the DocumentView user control? Fyi I am using a Grid layout to style the child rows: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="34"/> <ColumnDefinition Width="100"/> <ColumnDefinition Width="*" /> <ColumnDefinition Width="60" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <TextBlock Grid.ColumnSpan="4" Grid.Row="0" Text="Should only show this at the top"></TextBlock> <Image Grid.Column="0" Grid.Row="1" Height="24" Width="24" Source="/Beazley.Documents.Presentation;component/Icons/error.png"></Image> <ComboBox Grid.Column="1" Grid.Row="1" Name="ContentTypes" ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainView}}, Path=DataContext.ContentTypes}" SelectedValue="{Binding ContentType}"/> <TextBox Grid.Column="2" Grid.Row="1" Text="{Binding Path=FileName}"/> <Button Grid.Column="3" Grid.Row="1" Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainView}}, Path=DataContext.RemoveFile}" CommandParameter="{Binding}">Remove</Button> </Grid>

  • Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

    - by Relequestual
    I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made.

  • Javascript (JQuery) keyboard hijack problem

    - by user266564
    I'm making a typing tutor program using javascript. Everything is going well except that if activates browser hotkeys which disrupts the functionality of the program. When I press the single quote in Firefox it triggers "Quick find (links only)" short cut and in all browsers when I press space the page scrolls down a page. Everything is working fine outside of this. Here's the code in the head: <script type="text/javascript"> $(document).ready(function() { executeType(); }); </script> And the code I am using to capture the keyboard (simplified, but tested): function executeType() { $(document).keydown(function(event) { alert(event.keyCode); }); }

  • Cleaning up a sparsebundle with a script

    - by nickg
    I'm using time machine to backup some servers to a sparse disk image bundle and I'd like to have a script to clean up the old back ups and re-size the image once space has been freed up. I'm fairly certain the data is protected because if I delete the old backups by right clicking, I have to enter a password to be able to delete them. To allow my script to be able to delete them, I've been running it as root. For some reason, it just won't run and every file it tries to delete I get rm: /file/: Operation not permitted Here is what I have as my script: #!/bin/bash for server in servername; do /usr/bin/hdiutil attach -mountpoint /path/to/mountpoint /path/to/sparsebundle/$server.sparsebundle/; /bin/sleep 10; /usr/bin/find /path/to/mountpoint -type d -mtime +7 -exec /bin/rm -rf {} \; /usr/bin/hdiutil unmount /path/to/mountpoint; /bin/sleep 10; /usr/bin/hdiutil compact /path/to/sparsebundle/$server.sparsebundle/; done exit; One of the problems I thought was causing this was it needed to have a mountpoint specified since the default mount was to /Volumes/Time\ Machine\ Backups/ that's why I created a mountpoint. I also thought that it was trying to delete the files to quickly after mounting and it wasn't actually mounted yet, that's why I added the sleep. I've also tried using the -delete option for find instead of -exec, but it didn't make any difference. Any help on this would be greatly appreciated because I'm out of ideas as to why this won't work.

  • Access/Download server files, not in site root, with PHP

    - by user271619
    Usually I save documents (images, mpegs, excel, word docs, etc...) for my friends or family on my website's root, inside a directory called /files/ or something similar. Nothing too uncommon. But, I have been playing with user session control, and allowing users to upload files to the dedicated /files/ directory. (the file names are saved in a db, with that user's ID) But, that means other people could try to guess and locate other people's files. I do randomize the file names, upon upload. And I stop the apache from displaying the /files/ directory content. However, I'd like to start saving the files outside of the website's root. This way it can't be accessible via the browser. I don't have any code to show, but I didn't want to even start on this endeavor if it's not able to be accomplished. I did find this snippet that shows how to display an image, from outside your website root: $file = $_GET['file']; $fileDir = '/path/to/files/'; if (file_exists($fileDir . $file)) { // Note: You should probably do some more checks // on the filetype, size, etc. $contents = file_get_contents($fileDir . $file); // Note: You should probably implement some kind // of check on filetype header('Content-type: image/jpeg'); echo $contents; } ? Maybe I can use this for any file type, but has anyone heard of a better way to allow users (logged in) to access their files from online, but not letting other users has similar access?

  • How do I POST/GET from rails to API with either ActiveResource or rest-client (preferred)?

    Hi, this is a pretty basic question but I'm not entirely clear how to do this. I am trying to use a third-party service that has RESTful service. The service is called Postful. But I'm not clear what exactly to do? I've looked at ActiveResource (http://api.rubyonrails.org/classes/ActiveResource/Base.html) and rest-client, but I'm still not clear exactly what steps, code, and files to create. http://www.postful.com/service/mail is one of the services (details found http://www.postful.com/developer/guide#rest ), but to upload an image I have to post the following (but I'm not sure how I actually do this?). Thanks! > http://www.postful.com/service/upload > > Be sure to include the Content-Type > and Content-Length headers and the > image itself as the body of the > request. > > POST /upload HTTP/1.0 Content-Type: > application/octet-stream > Content-Length: 301456 > > ... file content here ... > > If the upload is successful, you will > receive a response like the following: > > <?xml version="1.0" encoding="UTF-8"?> > <upload> > <id>290797321.waltershandy.2</id> > </upload>

  • How to show jQuery is working/waiting/loading ?

    - by Kim
    How do I show a loading picture and/or message to the user ? If possible, would I like to know how to make it full screen with grey-dimmed background. Kinda like when viewing the large picture from some galleries (sorry, no example link). Currently do I add a CSS class which has the image and other formating, but its not working for some reason. Results from the search do get inserted into the div. HTML <div id="searchresults"></div> CSS div.loading { background-image: url('../img/loading.gif'); background-position: center; width: 80px; height: 80px; } JS $(document).ready(function(){ $('#searchform').submit(function(){ $('#searchresults').addClass('loading'); $.post('search.php', $('#'+this.id).serialize(),function(result){ $('#searchresults').html(result); }); $('#searchresults').removeClass('loading'); return false; }); });

  • Does android maps support ground overlay?

    - by wmh1108
    I have a weather image I would like to use as an overlay in the google maps android api. I would like to achieve the same result that I get from using GroundOverlay in KML files, such as <GroundOverlay> <name>myimage</name> <Icon> <href>myimage.png</href> <viewBoundScale>0.75</viewBoundScale> </Icon> <LatLonBox> <north>75.6088</north> <south>5.0121</south> <east>182.2805</east> <west>120.6795</west> </LatLonBox> </GroundOverlay> The above will ensure that the 4 corners of my image stay anchored to the 4 lat/long points listed, regardless of scrolling, zooming etc.. Is there a way to accomplish this using the google api/maps provided for android?

  • getting started with SMS developement

    - by I__
    i will have the following set up: people will be sending text messages to a server, and that server will be forwarding the messages to other phone numbers i am not sure what kind of framework i should use. should i develop an SMS gateway and use AT commands? should i just try to somehow use AIM or GCHAT to capture and send SMS messages? would there be a different more suitable configuration? are there already developed frameworks that are free which i can use? for example i know that i can send an SMS to almost anyone through gchat or aim by sending a message to "+" and the number of the person. is this scalable and can i use it for my own benefit? any sms developers out there?

  • changing sounds when objects meet

    - by blacksheep
    i'd like to change sounds when tapping on an image and drag another image over several others. it is not working properly: the "MoveImage" is not dragable, the tapping is working outside the "TouchImage" and the sounds do not change when tapping on it. (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)))) { [sound_E play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)))) { [sound_F play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)))) { [sound_D play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)))) { [sound_Dis play]; } } (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if (CGRectContainsPoint(myMoveImage.frame, location)){ CGPoint yLocation = CGPointMake(myMoveImage.center.x,location.y); myMoveImage.center = yLocation; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)) { E_NOTE.text = @"E"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)) { F_NOTE.text = @"F"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)) { D_NOTE.text = @"D"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)) { Dis_NOTE.text = @"D#"; } }

  • Attention JavaScript gurus: Need a hand with setInterval()

    - by alex
    I am trying to make a non interactive display for a real estate shop window. It's been a while since I've played with setInterval(). The first time my script steps through, it is fine. But when it tries to get the next property via getNextProperty(), it starts to go haywire. If you have Firebug, or an equivalent output of console.log(), you'll see it is calling things it shouldn't! Now there is a fair bit of JavaScript, so I'll feel better linking to it than posting it all. Store Display Offending JavaScript It is worth mentioning all my DOM/AJAX is done with jQuery. I've tried as best to make sure clearInterval() is working, and it seems to not run any code below it. The setInterval() is used to preload the next image, and then display it in the gallery. When the interval detects we are at the last image ((nextListItem.length === 0)), it is meant to clear that interval and start over with a new property. It has been driving me nuts for a while now, so anyone able to help me? It is probably something really obvious! Many thanks!

  • How can I work out what events are being waited for with WinDBG in a kernel debug session

    - by Benj
    I'm a complete WinDbg newbie and I've been trying to debug a WindowsXP problem that a customer has sent me where our software and some third party software prevent windows from logging off. I've reproduced the problem and have verified that only when our software and the customers software are both installed (although not necessarily running at logoff) does the log off problem occur. I've observed that WM_ENDSESSION messages are not reaching the running windows when the user tries to log off and I know that the third party software uses a kernel driver. I've been looking at the processes in WinDbg and I know that csrss.exe would normally send all the windows a WM_ENDSESSION message. When I ran: !process 82356020 6 To look at csrss.exe's stack I can see: WARNING: Frame IP not in any known module. Following frames may be wrong. 00000000 00000000 00000000 00000000 00000000 0x7c90e514 THREAD 8246d998 Cid 0248.02a0 Teb: 7ffd7000 Win32Thread: e1627008 WAIT: (WrUserRequest) UserMode Non-Alertable 8243d9f0 SynchronizationEvent 81fe0390 SynchronizationEvent Not impersonating DeviceMap e1004450 Owning Process 82356020 Image: csrss.exe Attached Process N/A Image: N/A Wait Start TickCount 1813 Ticks: 20748 (0:00:05:24.187) Context Switch Count 3 LargeStack UserTime 00:00:00.000 KernelTime 00:00:00.000 Start Address 0x75b67cdf Stack Init f80bd000 Current f80bc9c8 Base f80bd000 Limit f80ba000 Call 0 Priority 14 BasePriority 13 PriorityDecrement 0 DecrementCount 0 Kernel stack not resident.

Can anyone tell me how I might find out what event it's waiting for anything else I might do to further investigate the problem?
