  • IE7/IE8 javascript drop down menu used to redirect not working

    - by Robbiegod
    The error I see from IE7/IE8 in Jquery v1.7.2 and v.1.7.1 - i tried both: SCRIPT438: Object doesn't support property or method 'apply' My Code: <form> <select id="stateD" OnChange="showState()"> <option value="none" selected="selected">==========</option> <option value="http://www.google.com">google</option> <option value="http://www.yahoo.com">Yahoo</option> </select> </form> My Javascript - I have this pasted just below the webform: <script type="text/javascript"> function showState(){ oStates = document.getElementById("stateD"); var jLink = $("#stateD :selected").val(); if (jLink == undefined || jLink == "none" ){ alert("Please Select a State"); } else{ document.location.href=jLink}; } </script> I'm not using 2 libraries so i don't get why its having a problem. All that is supposed to happen is you select a url from the drop down menu and it auto sends you to that url that is in the value of the option tag. Works everywhere else, not sure why IE has to be such a jerk today. I'd post a url but i can't at the moment. its private. has anyone encountered this issue before?

  • Powershell Select-Object from array not working

    - by Andrew
    I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

  • The question about the basics of LINQ to SQL working

    - by Alex
    I just started learning LINQ to SQL, and so far I'm impressed with the easy of use and good performance. I used to think that when doing LINQ queries like from Customer in DB.Customers where Customer.Age > 30 select Customer Get all customers from the database ("SELECT * FROM Customers"), move them to the Customers array and then make a search in that Array using .NET methods. This is very inefficient, what if there are hundreds of thousands of customers in the database? Making such big SELECT queries would kill the web application. Now after experiencing how actually fast LINQ to SQL is, I start to suspect that when doing that query I just wrote, LINQ somehow converts it to a SQL Query string SELECT * FROM Customers WHERE Age > 30 And only when necessary it will run the query. So my question is: am I right? And when is the query actually run? The reason why I'm asking is not only because I want to understand how it works in order to build good optimized applications, but because I came across the following problem. I have 2 tables, one of them is Books, the other has information on how many books were sold on certain days. My goal is to select books that had at least 50 sales/day in past 10 days. It's done with this simple query: from Book in DB.Books where (from Sale in DB.Sales where Sale.SalesAmount >= 50 and Sale.DateOfSale >= DateTime.Now.AddDays(-10) select Sale.BookID).Contains(Book.ID) select Book The point is, I have to use the checking part in several queries and I decided to create an array with IDs of all popular books: var popularBooksIDs = from Sale in DB.Sales where Sale.SalesAmount >= 50 and Sale.DateOfSale >= DateTime.Now.AddDays(-10) select Sale.BookID; BUT when I try to do the query now: from Book in DB.Books where popularBooksIDs.Contains(Book.ID) select Book It doesn't work! That's why I think that we can't use thins kinds of shortcuts in LINQ to SQL queries, like we can't use them in real SQL. We have to create straightforward queries, am I right?

  • Catching KeyboardInterrupt when working with PyGame

    - by Sebastian P.
    I have written a small Python application where I use PyGame for displaying some simple graphics. I have a somewhat simple PyGame loop going in the base of my application, like so: stopEvent = Event() # Just imagine that this eventually sets the stopEvent # as soon as the program is finished with its task. disp = SortDisplay(algorithm, stopEvent) def update(): """ Update loop; updates the screen every few seconds. """ while True: stopEvent.wait(options.delay) disp.update() if stopEvent.isSet(): break disp.step() t = Thread(target=update) t.start() while not stopEvent.isSet(): for event in pygame.event.get(): if event.type == pygame.QUIT: stopEvent.set() It works all fine and dandy for the normal program termination; if the PyGame window gets closed, the application closes; if the application finishes its task, the application closes. The trouble I'm having is, if I Ctrl-C in the Python console, the application throws a KeyboardInterrupt, but keeps on running. The question would therefore be: What have I done wrong in my update loop, and how do I rectify it so a KeyboardInterrupt causes the application to terminate?

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

  • Streaming audio not working in Android

    - by user320293
    Hi, I'm sure that this question has been asked before but I've been unable to find a solid answer. I'm trying to load a streaming audio from a server. Its a audio/aac file http://3363.live.streamtheworld.com:80/CHUMFMAACCMP3 The code that I'm using is private void playAudio(String str) { try { final String path = str; if (path == null || path.length() == 0) { Toast.makeText(RadioPlayer.this, "File URL/path is empty", Toast.LENGTH_LONG).show(); } else { // If the path has not changed, just start the media player MediaPlayer mp = new MediaPlayer(); mp.setAudioStreamType(AudioManager.STREAM_MUSIC); try{ mp.setDataSource(getDataSource(path)); mp.prepareAsync(); mp.start(); }catch(IOException e){ Log.i("ONCREATE IOEXCEPTION", e.getMessage()); }catch(Exception e){ Log.i("ONCREATE EXCEPTION", e.getMessage()); } } } catch (Exception e) { Log.e("RPLAYER EXCEPTION", "error: " + e.getMessage(), e); } } private String getDataSource(String path) throws IOException { if (!URLUtil.isNetworkUrl(path)) { return path; } else { URL url = new URL(path); URLConnection cn = url.openConnection(); cn.connect(); InputStream stream = cn.getInputStream(); if (stream == null) throw new RuntimeException("stream is null"); File temp = File.createTempFile("mediaplayertmp", ".dat"); temp.deleteOnExit(); String tempPath = temp.getAbsolutePath(); FileOutputStream out = new FileOutputStream(temp); byte buf[] = new byte[128]; do { int numread = stream.read(buf); if (numread <= 0) break; out.write(buf, 0, numread); } while (true); try { stream.close(); } catch (IOException ex) { Log.e("RPLAYER IOEXCEPTION", "error: " + ex.getMessage(), ex); } return tempPath; } } Is this the correct implementation? I'm not sure where I'm going wrong. Can someone please please help me on this.

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post.

  • Sharepoint alerts not working when multiple people are in an item

    - by csm8118
    We use Sharepoint Services 3.0 as a project tracking tool. We have a list set up that contains your basic information (description, etc.) plus we have a "assigned person" column that is of type Person or Group that we use to associate list items with individuals. This column supports multiple selections. We would like to set up alerts such that each person gets an alert email only if they are assigned to a list item. The approach we have taken is to set up a view on this list that is filtered to show list items where the assigned person equals [Me], and then to create an alert on this list that is set to send an email when someone changes an items that appears in the view. This works well when there is only one person in the assigned person column. It does not work when there is more than one person in the assigned person column. Does anybody know why this wouldn't work, or what I can do to troubleshoot? Is there a better way to achieve the end result? We could make several "assigned person" columns and not allow multiple selections, but that seems kind of kludgy.

  • MYSQL LIMIT not working as expected - Java

The problem is if I need to set a minLength validation rule in the model, it doesn't work since the Auth component hashes the password therefore it's always more than my minlength password and it passes even if it's blank. How do I fix this issue? Thanks in advance!

  • How to get acts on taggable working

    - by Schipperius
    I am new to ruby on rails (and programming) and this is probably a really stupid question. I am using Rails 3.2 and trying to use acts_as_taggable_on to generate tags on articles and to have those tags show on article index and show pages as a clickable links. I have tags clickable on both the article show and index pages, but the links just go back to the index page and don't sort according to the tag name. I have scoured the Internet and pieced together the code below from various sources, but I am clearly missing something. Any help is greatly appreciated, as I have exhausted my seemingly limited knowledge! Thanks. Here is what I have: class ArticlesController < ApplicationController def tagged @articles = Article.all(:order => 'created_at DESC') @tags = Article.tag_counts_on(:tags) @tagged_articles = Article.tagged_with(params[:tags]) respond_to do |format| format.html # index.html.erb format.json { render :json => @articles } end end def index @article = Article.new @articles = Article.paginate :page => params[:page], :per_page => 3 @tags = Article.tag_counts_on(:tags) respond_to do |format| format.html # index.html.erb format.json { render json: @articles } end end module ArticlesHelper include ActsAsTaggableOn::TagsHelper end class Article < ActiveRecord::Base acts_as_ordered_taggable acts_as_ordered_taggable_on :tags, :location, :about attr_accessible :tag_list scope :by_join_date, order("created_at DESC") end article/index.html.erb <% tag_cloud(@tags, %w(tag1 tag2 tag3 tag4)) do |tag| %> <%= link_to tag.name, articles_path(:id => tag.name) %> <% end %> article/show.html.erb <%= raw @article.tags.map { |tag| link_to tag.name, articles_path(:tag_id => tag) }.join(" | ") %>

  • Working with fields which can mutate or be new instances altogether

    - by dotnetdev
    Structs are usually used for immutable data, eg a phone number, which does not mutate, but instead you get a new one (eg the number 000 becoming 0001 would mean two seperate numbers). However, pieces of information like Name, a string, can either mutate (company abc changing its name to abcdef, or being given a new name like def). For fields like this, I assume they should reside in the mutable class and not an immutable structure? My way of structuring code is to have an immutable concept, like Address (any change is a new address completely), in a struct and then reference it from a class like Customer, since Customer always has an address. So I would put CompanyName, or Employer, in the class as it is mutable. But a name can either mutate and so be the same 1 instance, or a new name setup and while the company still owning the first name too. Would the correct pattern for assigning a new instance (eg a new company name but the old name still owned by the company) be?: string name = ""; string newName = new string(); newName = "new"; name = newName; And a mutation just the standard assignment pattern? Thanks

  • Form iteration function not working properly

    - by Moses
    My function is supposed to iterate all forms in the document, and bind an onclick function to each 'calculate' element int he form. The problem is, the function that executes on any of the click events executes in the context of the the last i in the loop. Here is the JavaScript that I'm using: window.onload = function(){ calculateSavings(); } function calculateSavings(){ for (i = 0; i < document.forms.length; i++) { var e = document.forms[i]; e.calculate.onclick = function() { var hours = e.hours.value; var rate = e.rate.value; alert(hours * rate); } } } And here is the HTML it is attached to: <!doctype html> <html> <body> <form> <label for="hours">Hours: </label><input type="text" id="hours" name="hours"> <label for="rate">Rate: </label><input type="text" id="rate" name="rate"> <input type="button" name="calculate" value="Calculate"> <div id="savings"></div> </form> <form> <label for="hours">Hours: </label><input type="text" id="hours" name="hours"> <label for="rate">Rate: </label><input type="text" id="rate" name="rate"> <input type="button" name="calculate" value="Calculate"> <div id="savings"></div> </form> </body> </html> I'm sure this is a really basic question but the solution is completely eluding me at this point.

  • PHP using a passed value to open a dir, not working

    - by HadoukenGr
    This is my code <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Gallery</title> <script src="js/jquery-1.7.2.min.js"></script> <script src="js/lightbox.js"></script> <link href="css/lightbox.css" rel="stylesheet" /> </head> <body> <?php $value=$_GET["value"]; $handle = opendir("content/$value/gallery/"); while($file = readdir($handle)) { if($file !== '.' && $file !== '..') { do_something; } } ?> </body> </html> Passing value "?a??????", gives Warning: opendir(content/?a??????/gallery/): failed to open dir: No such file or directory. But if i do this : $handle = opendir("content/?a??????/gallery/"); it works fine. Something to do with character encoding? How could i solve this? Thank you.

  • Iframe auto-height not working when page changes in IE

    - by DisgruntledGoat
    I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?
