  • Why does my Android App crash when loading image from gallery the 2nd time?

    - by Sebastian
    Hi folks, I've written an app, thats loading images either using the android gallery app or by taking a photo using the cam. When I now load an image using the gallery, everything is fine. When the code is being executed a second time (for loading another image), the application crashes. try { Uri data = intent.getData(); ContentResolver cr = this.getContentResolver(); Bitmap mBitmap = null; mBitmap = Media.getBitmap(cr, data); imageView.setImageBitmap(mBitmap); } catch(Exception e){ showToast(this, "Failed loading image from gallery"); return; } The code crashes at the line mBimap = Media.getBitmap(cr, data);. Everything is initialized, there are no null values etc. The strange thing is: no exception is thrown, I don't get into the catch block to determine whats going wrong. Does anyone have an idea about this? Am I not allowed to "re-use" the content resolver? Do I have to free it after the first usage or something like this?

  • posting a variable with jquery and receiving it on other page

    - by Billa
    I want to post a varible "id" to a page. I'm trying following code, but I cant get the id value, it says "undefined". function box(){ var id=$(this).attr("id"); $("#votebox").slideDown("slow"); $("#flash").fadeIn("slow"); $.ajax({ type: "POST", //I want to post the "id" to the rating page. data: "id="+$(this).attr("id"), url: "rating.php", success: function(html){ $("#flash").fadeOut("slow"); $("#content").html(html); } }); } This function is called in following code. In the following code too, the id is posted to the page "votes.php", and it works fine, but in the above code when I'm trying to post the id to the rating.php page, it does not send. $(function(){ $("a.vote_up").click(function(){ the_id = $(this).attr('id'); $("span#votes_count"+the_id).fadeOut("fast"); $.ajax({ type: "POST", data: "action=vote_up&id="+$(this).attr("id"), url: "votes.php", success: function(msg) { $("span#votes_up"+the_id).fadeOut(); $("span#votes_up"+the_id).html(msg); $("span#votes_up"+the_id).fadeIn(); var that = this; box.call(that); } }); }); }); rating.php <? $id = $_POST['id']; echo $id; ?> The html part is: <a href='javascript:;' class='vote_up' id='<?php echo $row['id']; ?>'>Vote Up!</a> I'll appriciate any help.

  • How do I avoid having JSONP returns cached in an HTML5 offline application?

    - by Kent Brewster
    I had good luck with cached offline apps until I tried including data from JSONP endpoints. Here's a tiny example, which loads a single movie from the new Netflix widget API: <!DOCTYPE html> <html manifest="main.manifest"> <head> <title>Testing!</title> </head> <body> <p>Attempting to recover a title from Netflix now...</p> <script type="text/javascript"> function ping(r) { alert('API reply: ' + r.catalog_title.title.regular); } var cb = new Date().getTime(); var s = document.createElement('SCRIPT'); s.src = 'http://movi.es/7Soq?v=2.0&output=json&expand=widget&callback=ping&cacheBuster=' + cb; alert('SCRIPT src: ' + s.src); s.type = 'text/javascript'; document.getElementsByTagName('BODY')[0].appendChild(s); </script> </body> </html> ... and here's the contents of my manifest, main.manifest, which contains no files and is only there so my browser knows to cache the calling HTML file. CACHE MANIFEST Yes, I've confirmed that my server is sending the manifest down with the correct content type, text/cache-manifest. The app works fine--meaning both alerts show--the first time I run it, but subsequent runs, even with the attempt at cache-busting in line 10, seem to be attempting to load the script from cache no matter what the query string is. I see the alert showing the script source, but the callback never fires. If I remove the manifest link from line 2 and reset my browser--being Safari and the iPhone Simulator--to clear cache, it works every time. I've also tried alerting the number of SCRIPT tags in the page, and it's definitely seeing both the existing and dynamically-created tag in all cases.

  • iPhone: How to Determine Average Light/Dark of an Area of an UIImage

    - by TechZen
    I need to place labels with a transparent background over a variable-content UIImage. Readability will vary significantly depending on the relationship between the color of the label's text and the color/luminosity of the area of the image displayed under the label. Since the image will be constantly changing, the color of the label's text needs to change in sync. I have found several techniques for determining the color, perceived luminosity etc of a single pixel. However, I need to rather quickly (while a view loads) determine the rough perceived color/luminosity of an area of the UIImage under the frame of the UILabel. I presume I will also need to measure the alpha because the same color/luminosity looks different at different alpha values. Is there a way to calculate such a value for an area? Will I be reduced to simply summing pixels? If it comes to that, is there an algorithm to accomplish this? I've thought of two possible approaches: Perform some "folding" operations i.e. combining pixels from one half of the area to the other half. Then repeat until I get a single value. Would this be practical? How would you logically combine pixels to average their perceived color/luminosity? Sample a statistically significant number of pixels in the area and then combine them (somehow) to get a rough measure. I think this problem comes up a lot these days with people being so found of customizing backgrounds. Seems like something that would be worth my time to bang out a category or class to handle this and then share it around.

  • jquery lightbox multiple items to look like mac dashboard

    - by Don
    Hope the title says it all... I'm wondering if it's possible in any existing lightbox to pop up a look similar to the mac dashboard where multiple divs could be "on" in the front with the main webpage with a gray overlay. Basically something where a user clicks an icon on the main webpage to call, and then 4 separate content boxes are popped on top, but not in a window like a gallery. I'm thinking the top background used could be set to transparent and the individual items could be divs on the popped area, but before I reinvent the wheel, I thought I'd see if there's something like this that I just haven't found in my searches. UPDATE: 1/7/2011 I ended up using colorbox with a background behind my divs. It doesn't look like the mac with items having the bg behind them showing between them, but after talking to the designer I'm working with, that wasn't something they really needed anyhow. I think it MAY be possible changing some of the CSS though for the bg of the "popped" window. Colorbox seems to be pretty nice about making it clear what the CSS is doing and there are multiple example skins. Just my $0.02...

  • Clear tableView cell cache (or remove an entry)

    - by ManniAT
    Hi, I have the same question problem as described here http://stackoverflow.com/questions/2286669/iphone-how-to-purge-a-cached-uitableviewcell But my problem can't be solved with "resetting content". To be precise - I use a custom cell (own class). While running the application it is possible that I have to use a different "cell type". It's the same class - but it has (a lot of) differnt attributes. Of course I could always reset all the things at "PrepareForReuse" but that's not a good idea I guess (there are a lot things to reset). My idea - I do all these things in the constructor of the cell. And all the rows will use this "type of cell" later. When the (seldom) situation comes that I have to change the look of all rows I create a new instance of this kind of cell with different settings. And now I want to replace the queued cell with this new one. I tried it with simply calling the constructor with the same cellidentifier (in the hope it will replace the existing one) but that doesn't work. I also didn't find a "ClearReusableCells" or something like this. Is there a way to clear the cache - or to remove / replace a specific item? Manfred

  • getting data from dynamic schema

    - by coure2011
    I am using mongoose/nodejs to get data as json from mongodb. For using mongoose I need to define schema first like this var mongoose = require('mongoose'); var Schema = mongoose.Schema; var GPSDataSchema = new Schema({ createdAt: { type: Date, default: Date.now } ,speed: {type: String, trim: true} ,battery: { type: String, trim: true } }); var GPSData = mongoose.model('GPSData', GPSDataSchema); mongoose.connect('mongodb://localhost/gpsdatabase'); var db = mongoose.connection; db.on('open', function() { console.log('DB Started'); }); then in code I can get data from db like GPSData.find({"createdAt" : { $gte : dateStr, $lte: nextDate }}, function(err, data) { res.writeHead(200, { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }); var body = JSON.stringify(data); res.end(body); }); How to define scheme for a complex data like this, you can see that subSection can go to any deeper level. [ { 'title': 'Some Title', 'subSection': [{ 'title': 'Inner1', 'subSection': [ {'titile': 'test', 'url': 'ab/cd'} ] }] }, .. ]

  • Variable not implementing correctly from if statement

    - by swiftsly
    I have an if statement that is supposed to set the variable $pc162v to a link specified in the MySQL table if content exists in the $vid column of the row. The problem is, the PHP is detecting that there's a link in the MySQL, but isn't setting the $pc162v variable correctly. Here's the variable declarations: $pc162v = ""; $vid162 = '<embed width="420" height="236" src="'.$pc162v.'" type="application/x-shockwave-flash"></embed>'; Here's the section of the if statement: if (empty($row[7])) { $vid162 = ''; } else { $pc162v = $row[7]; } In my web browsers, the part of the code where the variable $vid162 is used, shows up as the following: <embed width="420" height="236" src="" type="application/x-shockwave-flash"> I have also tried setting $vid162 to: <embed width="420" height="236" src="<?php echo $pc162v; ?>" type="application/x-shockwave-flash"></embed> and that just makes the code in my web browser: <embed width="420" height="236" src="<?php echo $pc162v; ?>" type="application/x-shockwave-flash"> Hope someone has a solution! Thanks in advance.

  • Focus-dependent text change for TextBoxes in WPF

    - by Simon
    Hey there. I'm writing an application in WPF using the MVVM-pattern and will really often use TextBoxes. I don't want to use labels for the user to know user what the text box is for, i.e. I don't want something like this: <TextBlock> Name: </TextBlock> <TextBox /> Instead, I would like the TextBox to contain its own label. Statically, you would express it like this: <TextBox>Name</TextBox> If the cursor is displayed in the textbox, i.e. the TextBox gains focus, I want the description text to disappear. If the TextBox is left empty and it loses the focus, the description text should be shown again. It's similar to the search textbox of StackOverflow or the one of Firefox. (please tell me if your not sure what I mean). One TextBox's label may change at runtime, dependending on e.g. a ComboBox's selected element or a value in my ViewModel. (It's like in Firefox's search TextBox, if you select google from the search engins' menu, the TextBox's label changes to "Google", if you select "Yahoo" its set to "Yahoo"). Thus I want to be able to bind the label's content. Consider that I may already have a Binding on the Text-Property of the TextBox. How can implement such a behaviour and make it reusable for any of my TextBox's? Code is welcome but not needed; a description of what to do is enough. Thank you in advance.

  • WPF Binding to variable / DependencyProperty

    - by Peter
    I'm playing around with WPF Binding and variables. Apparently one can only bind DependencyProperties. I have come up with the following, which works perfectly fine: The code-behind file: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public string Test { get { return (string)this.GetValue(TestProperty); } set { this.SetValue(TestProperty, value); } //set { this.SetValue(TestProperty, "BBB"); } } public static readonly DependencyProperty TestProperty = DependencyProperty.Register( "Test", typeof(string), typeof(MainWindow), new PropertyMetadata("CCC")); private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show(Test); Test = "AAA"; MessageBox.Show(Test); } } XAML: <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Title="MainWindow" Height="350" Width="525" DataContext="{Binding RelativeSource={RelativeSource Self}}"> <Grid> <TextBox Height="31" HorizontalAlignment="Left" Margin="84,86,0,0" Name="textBox1" VerticalAlignment="Top" Width="152" Text="{Binding Test, Mode=TwoWay, diag:PresentationTraceSources.TraceLevel=High}"/> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="320,85,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> <TextBox Height="31" HorizontalAlignment="Left" Margin="84,138,0,0" Name="textBox2" Text="{Binding Test, Mode=TwoWay}" VerticalAlignment="Top" Width="152" /> </Grid> The two TextBoxes update one an other. And the Button sets them to "AAA". But now I replaced the Setter function with the one that is commented out (simulating some manipulation of the given value). I would expect that whenever the property value is changed it will be reset to "BBB". It does so when you press the button, that is when you set the property in code. But it does for some reason not affect the WPF Bindings, that is you can change the TextBox contents and thus the property, but apparently the Setter is never called. I wonder why that is so, and how one would go about to achive the expected behaviour.

  • Android XML Preference issue. Can't make it persistent

The value is still there. But that's it... if I click the Back button, and enter the again on the preferences screen, I already lost what was written. If you exit the application also doesn't save. Am I missing something here? Running on: Android 4.0.3 Asus TF300

    I'm writting a java class that tests uploading speed connection to a server. I want to check how many data can be send in 5 seconds. I've written a class which creates a URL, creates a connection, and sends data trough the outPutStream. There is a loop where I writte data to the stream for 5 seconds. However I'm not able to see when data has been send (I writte data to the output stream, but data is not send yet). How can I wait untill data is really sent to the server?

  • Can I access views when drawn in the drawRect method?

    - by GianPac
    When creating the content view of a tableViewCell, I used the drawInRect:withFont, drawAtPoint... and others, inside drawRect: since all I needed was to lay some text. Turns out, part of the text drawn need to be clickable URLs. So I decided to create a UIWebView and insert it into my drawRect. Everything seems to be laid out fine, the problem is that interaction with the UIWebView is not happening. I tried enabling the interaction, did not work. I want to know, since with drawRect: I am drawing to the current graphics context, there is anything I can do to have my subviews interact with the user? here is some of my code I use inside the UITableViewCell class. -(void) drawRect:(CGRect)rect{ NSString *comment = @"something"; [comment drawAtPoint:point forWidth:195 withFont:someFont lineBreakMode:UILineBreakModeMiddleTruncation]; NSString *anotherCommentWithURL = @"this comment has a URL http://twtr.us"; UIWebView *webView = [[UIWebView alloc] initWithFrame:someFrame]; webView.delegate = self; webView.text = anotherCommentWithURL; [self addSubView:webView]; [webView release]; } As I said, the view draws fine, but there is no interaction with the webView from the outside. the URL gets embedded into HTML and should be clickable. It is not. I got it working on another view, but on that one I lay the views. Any ideas?

  • Multiple grids in one area

    - by anon
    I'm currently creating a WPF application, using C# and XAML in Visual Studios 2010. I have a master grid. In that master grid I have a group bar which you can select different items. Depending on what you select, the middle of the master grid can be totally different. What I was wondering is, what's the best way to program the middle part? Right now, I have it set up in such a way that everything in the middle is dynamically programed in C#, and everything on the outside is programmed in XAML. In C# I programmed: for each group bar item, there is a grid that goes with it (so that different content can be displayed on it). Each grid is a child of the master grid. Each grid is visible or hidden when necessary. Is this the best way to approach this? The best example of this is in Outlook 2007, where you have your group bar on the right hand side. When you select different items on the group bar (mail, calendar, tasks) the right of the group bar completely changes.

  • XSD: Different sub-elements depending on attribute/element value

    - by AndiDog
    Another XSD question - how can I achieve that the following XML elements are both valid: <some-element> <type>1</type> <a>...</a> </some-element> <some-element> <type>2</type> <b>...</b> </some-element> The sub-elements (either <a> or <b>) should depend on the content of <type> (could also be an attribute). It would be so simple in RelaxNG - but RelaxNG doesn't support key integrity :( Is there a way to implement this in XSD? Note: XML schema version 1.1 supports <xs:alternative>, which might be a solution, but afaik no reference implementation (e.g. libxml2) supports this yet. So I'm searching for workarounds. The only way I've come up with is: <type>1</type> <some-element type="1"> <!-- simple <xs:choice> between <a> and <b> goes here --> <a>...</a> </some-element> <!-- and now create a keyref between <type> and @type -->

Back end handling where i can do all content handling as well as other admin task a console which will be capable of handling everything from ceating importing contents to everything. 2 USer end which is only an interface to the end user to use the application. to visualize the things its kinda e-commerce application one is back office management and other is user end of web-shop. since these two module will be very much interlinked but i don't want them to mix up i want them to develop independently since admin is one which is core and it will also going to serve user interface. my question is how i can develop two module independently but on the other hand i want them to co-operate to accomplish the task as a whole. Really sorry in advance if i am not making any sense. Thanks in advance

  • How to change tab background on viewpagerindicator tabs?

    - by user1736277
    I am using ViewpagerIndicator library by Jake Wharton. I am using the tabs code in conjunction with the ActionBarSherlock library. Everything works fine, but I'm trying to style the background of the tabs and can't figure out how. I would like a dark action bar with dark tabs and light fragments (tab content). The base theme I am using is Theme.Sherlock.Light.DarkActionBar. I extend this style by making it the parent of a style that sets attributes for the tabs (like text color, indicator color, etc). This results in dark actionbar, light tabs, and light fragments. I can't find anything that will change the background of the tabs themselves. The only way I can change it is by changing the whole app to dark (using Theme.Sherlock). Here's my code so far: <style name="vpiTheme" parent="Theme.Sherlock.Light.DarkActionBar"> <item name="vpiTabPageIndicatorStyle">@style/CustomTabPageIndicator</item> </style> <style name="CustomTabPageIndicator" parent="Widget.TabPageIndicator"> <item name="android:textColor">#FF000000</item> <item name="android:paddingTop">6dp</item> <item name="android:paddingBottom">6dp</item> <item name="android:paddingLeft">16dip</item> <item name="android:paddingRight">16dip</item> <item name="android:maxLines">2</item> </style>

  • grailsApplication access in Grails unit Test

    - by Reza
    I am trying to write unit tests for a service which use grailsApplication.config to do some settings. It seems that in my unit tests that service instance could not access the config file (null pointer) for its setting while it could access that setting when I run "run-app". How could I configure the service to access grailsApplication service in my unit tests. class MapCloudMediaServerControllerTests { def grailsApplication @Before public void setUp(){ grailsApplication.config= ''' video{ location="C:\\tmp\\" // or shared filesystem drive for a cluster yamdi{ path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\yamdi" } ffmpeg { fileExtension = "flv" // use flv or mp4 conversionArgs = "-b 600k -r 24 -ar 22050 -ab 96k" path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\ffmpeg" makethumb = "-an -ss 00:00:03 -an -r 2 -vframes 1 -y -f mjpeg" } ffprobe { path="C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\ffprobe" params="" } flowplayer { version = "3.1.2" } swfobject { version = "" qtfaststart { path= "C:\\FFmpeg\\ffmpeg-20121125-git-26c531c-win64-static\\bin\\qtfaststart" } } ''' } @Test void testMpegtoFlvConvertor() { log.info "In test Mpg to Flv Convertor function!" def controller=new MapCloudMediaServerController() assert controller!=null controller.videoService=new VideoService() assert controller.videoService!=null log.info "Is the video service null? ${controller.videoService==null}" controller.videoService.grailsApplication=grailsApplication log.info "Is grailsApplication null? ${controller.videoService.grailsApplication==null}" //Very important part for simulating the HTTP request controller.metaClass.request = new MockMultipartHttpServletRequest() controller.request.contentType="video/mpg" controller.request.content= new File("..\\MapCloudMediaServer\\web-app\\videoclips\\sample3.mpg").getBytes() controller.mpegtoFlvConvertor() byte[] videoOut=IOUtils.toByteArray(controller.response.getOutputStream()) def outputFile=new File("..\\MapCloudMediaServer\\web-app\\videoclips\\testsample3.flv") outputFile.append(videoOut) } }

  • Powershell - Using variables in -Include filter

    - by TheD
    (again!) My final question for the night. I have a function which uses the Get-ChildItem to work out the newest file within a folder. The reason being I need to find the latest incremental backup in a folder and script an EXE to mount it. However, within this same folder there are multiple backup chains for all different servers: i.e. SERVER1_C_VOL_b001_i015.spi SERVER2_D_VOL_b001_i189.spi SERVER1_C_VOL_b002_i091.spi SERVER1_E_VOL_b002_i891.spi (this is the newest file created) I want only to look at SERVER1, look at only the C_VOL and look at only b001 - nothing else. I have all these seperate components: the drive letter, the Server Name, the b00X number stored in array. How then can I go and use the Get-ChildItem with the -Include filter to only look at: .spi SERVER1 C_VOL b001 Given I have all of these separate components in an array taken from a text file: Get-Content .\PostBackupCheck-TextFile.txt | Select-Object -First $i { $a = $_ -split ' ' ; $locationArray += "$($a[0]):\$($a[1])\$($a[2])" ; $imageArray += "$($a[2])_$($a[3])_VOL_b00$($a[4])_i$($a[5]).spi" } I then go onto try and filter then and then get stuck: $latestIncremental = Get-ChildItem -Path ${shadowProtectDataLocation}\*.* -Include *.spi | Sort-Object LastAccessTime -Descending | Select-Object -First 1 I have the .spi filtered, but how can I also just include the C (for volume), the number for the b00x and the server name. Thanks!
