  • Why is this unordered list formatting differently in IE7?

    - by Joel
    I'm better about getting things to look good in IE8, FF, and Safari, but IE7 still throws curve balls at me... Please check out this page and scroll down below the nav bar: http://rattletree.com/instruments.php It should become obvious when viewing in FF vs IE7. For some reason the formatting of the list is pushing the list items down on the page... any tips? <ul class="instrument"> <li class="imagebox"><img src="/images/stuff.jpg" width="247" height="228" alt="Matepe" /></li> <li class="textbox"><h3>Matepe</h3><p>This text should be to the right of the image but drops below the image in IE7</p></li> </ul> css: ul.instrument { text-align:left; display:inline-block; } ul.instrument li { list-style-type: none; display:inline-block; } li.imagebox { display:inline; margin:20px 0; padding:0px; vertical-align:top; } li.imagebox img{ border: solid black 1px; } li.textbox { display:inline; } li.textbox p{ margin:10px; width:340px; display:inline-block; }

  • How to get an embedded function to run multiple times

    - by Guy Montag
    The question I have is how to I get multiple instances of a function to run. Here is my function below - A simple fade function. Problem I'm having is that when it is called a second time it abandons the first call. So if a user clicks on a button it will display a message which fades. If the user clicks on another button the previous fading message just stops at the current opacity level. Try it here - www.arcmarks.com ( please do not repost this domain name) click on SignUp and than quickly click on SignIn with out typing anything. You will see the previous message simply halts. ? What is the stopping mechanism? Where did the previous function go? The function function newEffects(element, direction, max_time ) { newEffects.arrayHold = []; newEffects.arrayHold[element.id] = 0; function next() { newEffects.arrayHold[element.id] += 10; if ( direction === 'up' ) { element.style.opacity = newEffects.arrayHold[element.id] / max_time; } else if ( direction === 'down' ) { element.style.opacity = ( max_time - newEffects.arrayHold[element.id] ) / max_time; } if ( newEffects.arrayHold[element.id] <= max_time ) { setTimeout( next, 10 ); } } next(); return true; }; The Call newEffects(this.element, 'down', 4000 );

  • jQuery slideToggle jump on close

    - by spankmaster79
    Hi, I'm trying to slideToggle a in a table with jQuery and it works in FF, OP, CHrome. Only IE (6,7,8) is giving me problems. It slides down perfectly down and up, but after the slide up animation is finished. The hidden pops up in full height and then closes. So I guess it must be somwhere inbetween when it switches from a minimal height to "display:none" that it appears for a short second. The code is built dynamically but I'll try to give an example: <table> <tr> <td> <script type="text/javascript"> function toggleTr_{$dynamicID}() { $('#content_{$dynamicID}').slideToggle('slow'); /* DO SOME OTHER STOFF LIKE COLOR CHANGES CSS CLASS CHANGES */ } </script> </td> </tr> <tr id="list_{$dynamicID}" onclick="toggleTr_{$dynamicID}();" style="cursor:pointer;"> <td> <!-- INFO HEADER --> </td> </tr> <tr> <td> <div id="content_{$dynamicID}" style="display:none;"> <!-- INFO BODY HIDDEN --> </div </td> </tr> Other problems here with slideToggle only descibed problems with padding, margin, or problems with the animation, but that all works. Help is appreciated. Thx, Spanky

  • jQuery animation loop not working

    - by Marko Ivanovski
    Hi, I'm trying to create a looping animation that starts on onmousedown and stops on onmouseout. The effect is a simple scroll that will continue looping until you release the mouse. I've created a function which performs the .animate method and it passes itself as a callback but the code only runs once. Here's the entire code: $(document).ready(function() { var $scroller = $("#scroller"); var $content = $("#content", $scroller); // lineHeight equal to 1 line of text var lineHeight = $content.css('line-height'); //Amount to scroll = 3 lines of text a time var amountToScroll = lineHeight.replace("px","")*3; var maxScroll = $content.height() - $scroller.height(); function scrollDown() { var topCoord = $content.css("top").replace("px",""); if(topCoord > -maxScroll) { if((-maxScroll-topCoord) > -amountToScroll) { $content.stop().animate({ top: -maxScroll }, 1000 ); } else { $content.stop().animate({ top: "-=" + amountToScroll }, 1000, function(){ scrollDown() } ); } } } function scrollUp() { var topCoord = $content.css("top").replace("px",""); if(topCoord < 0) { if(topCoord > -amountToScroll) { $content.stop().animate({ top: 0 }, 1000 ); } else { $content.stop().animate({ top: "+=" + amountToScroll }, 1000, function(){scrollUp()} ); } } } $("#scroll-down").mousedown(function() { scrollDown(); }); $("#scroll-down").mouseup(function() { $content.stop(); }); $("#scroll-up").mousedown(function() { scrollUp(); }); $("scroll-up").mouseup(function() { $content.stop(); }); });

  • How to make div follow scrolling smoothly with jQuery?

    - by Martti Laine
    Hello I'm creating a blog layout, which has an sidebar. In sidebar there are sections/boxes, but the last one of these boxes should follow scrolling when none of the other boxes are visible. So, when user scrolls down, he sees a normal sidebar, but when user has went down enough, sidebar ends but the last box starts to follow on the top of the screen. I have seen this a lot on different kind of sites. So hard to explain with my english. I already made it to follow screen smoothly with animate() but couldn't get it like this. Hope you understood. I already tried in Google for almost an hour but couldn't figure out any keywords (due to my bad english). EDIT: My code at the moment: $(window).scroll(function(){ $.each($('.follow-scroll'),function(){ var eloffset = $(this).offset(); var windowpos = $(window).scrollTop(); if(windowpos<eloffset.top) { var finaldestination = 0; } else { var finaldestination = windowpos; } $(this).stop().animate({'top':finaldestination},200); }); });

  • Updated to Android 2.2 and now my apps input-lines don't show well, do I need to update my SDK?

    - by Allan
    My Android app has a couple input-lines made to receive numbers, it's a calc app. I just updated my Nexus One to Android 2.2 and now my apps input-lines don't respond like the way they should. When I touch the input-line, the Android keyboard used to pop-up just enough to kind of 'lift' the input-line above the keyboard - into the users view. Then when I scrolled down to the next input-line, that input-line used to 'lift-up' into view also. Now, after I updated my N1 to Android 2.2 - the input-lines are not lifting into view all the way. Also, when I scroll down to the next input-line and type in numbers - they don't appear, but when I scroll left...there they are. It's hard to describe my problem but things have definitely changed in the way my apps input-lines respond since the 2.2 update I did. If I try to update my SDk stuff in Eclipse and then recompile my app, might that fix it? Whenever there's an Android update - developers don't always have to recompile all of their apps do they?

  • Memory usage does not drop -- no leaks though

    - by climbon
    I have UINavigationController controlling several views. One of the views is composed of 20 scrollable pages. Each page is a constructed on the fly from UIViews by adding buttons, labels, UIImageViews etc. When this UIView is popped off the stack, the memory usage remains the same. Hence it keeps rising if I keep pushing/popping that view. In my dealloc, I am traversing through all 20 pages and finding each type of object which got added via addSubview and then do a release on it but instruments says my memory usage never goes down! I am trying to use 'retainCount' to see what is up with objects I am releasing but I am perhaps not getting true picture via retainCount. For some elements retainCount shows 2 so I try to release that object twice but then app crashes. If I release it once it works but memory usage never go down :( Q1: Do I need to traverse find each element and then do a release on that element ? Why can't I release a parent object and all objects contained by it would get released automatically ? Q2: Is retainCount a reliable indicator ?

  • find nearest match to array of doubles

    - by Scott
    Given the code below, how do I compare a List of objects's values with a test value? I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values. I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution. public class Location : IEnumerable { public string label { get; set; } public double lat { get; set; } public double lon { get; set; } //Implement IEnumerable public IEnumerator GetEnumerator() { return (IEnumerator)this; } } [HandleError] public class HomeController : Controller { private List<Location> myList = new List<Location> { new Location { label="Atlanta Midtown", lon=33.657674, lat=-84.423130}, new Location { label="Atlanta Airport", lon=33.794151, lat=-84.387228}, new Location { label="Stamford, CT", lon=41.053758, lat=-73.530979}, ... } public static int Main(String[] args) { string inLat = "-80.987654"; double dblInLat = double.Parse(inLat); // here's where I would like to find the closest location to the inLat // once I figure out this, I'll implement the Longitude, and I'll be set }

  • iMX31 dependencies?

    - by Abhi
    Dear all I am beginner in an silverlight application. So at first i looked on demo application which is provided by wince 6.0 r3 at location WINCE600\PUBLIC\COMMON\OAK\DEMOS\XAMLPERF - this contains c++ code and WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF - this contains xaml file with the images Now before running this application in an emulator. I at first proceeded with the following: I have first taken my workspace went to catalog item and added "Silverlight for Windows Embedded" from the drop down menu of an catalog item Then right clicked on solution explorer and choosed on properties and under configuration in drop down menu i have selected environment variables where i have added new variable called "sysgen_samplexamlperf" and assigned value as 1 for that variable. Now after rebuiding the application, i have dumped the image into emulator and i found that at desktop of device emulator i can see the exe file to which i run and i can see the application is working fine with 3d effects. Now same thing i proceeded in iMX31 hardware and i was not able to see the application running in a proper manner as it was performing in an emulator. So now what i feel is that there be any dependency when we run the application on hardware. So what can be the dependency? Also in this location "WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF" the images are in png format. So is there any dependency with an image format? Thanks and regards

  • How to cancel a deeply nested process

    - by Mystere Man
    I have a class that is a "manager" sort of class. One of it's functions is to signal that the long running process of the class should shut down. It does this by setting a boolean called "IsStopping" in class. public class Foo { bool isStoping void DoWork() { while (!isStopping) { // do work... } } } Now, DoWork() was a gigantic function, and I decided to refactor it out and as part of the process broke some of it into other classes. The problem is, Some of these classes also have long running functions that need to check if isStopping is true. public class Foo { bool isStoping void DoWork() { while (!isStopping) { MoreWork mw = new MoreWork() mw.DoMoreWork() // possibly long running // do work... } } } What are my options here? I have considered passing isStopping by reference, which I don't really like because it requires there to be an outside object. I would prefer to make the additional classes as stand alone and dependancy free as possible. I have also considered making isStopping a property, and then then having it call an event that the inner classes could be subscribed to, but this seems overly complex. Another option was to create a "Process Cancelation Token" class, similar to what .net 4 Tasks use, then that token be passed to those classes. How have you handled this situation? EDIT: Also consider that MoreWork might have a EvenMoreWork object that it instantiates and calls a potentially long running method on... and so on. I guess what i'm looking for is a way to be able to signal an arbitrary number of objects down a call tree to tell them to stop what they're doing and clean up and return.

  • Memory mapping of files and system cache behavior in WinXP

    - by Canopus
    Our application is memory intensive and deals with reading a large number of disk files. The total load can be more than 3 GB. There is a custom memory manager that uses memory mapped files to achieve reading of such a huge data. The files are mapped into the process memory space only when needed and with this the process memory is well under control. But what is observed is, with memory mapping, the system cache keeps on increasing until it occupies the available physical memory. This leads to the slowing down of the entire system. My question is how to prevent system cache from hogging the physical memory? I attempted to remove the file buffering (by using FILE_FLAG_NO_BUFFERING ), but with this, the read operations take considerable amount of time and slows down the application performance. How to achieve the scalability without sacrificing much on performance. What are the common techniques used in such cases? I dont have a good understanding of the WinXP OS caching behavior. Any good links explaining the same would also be helpful.

  • Adding new records in Access without wrecking the form

    - by Matt Parker
    I'm working on a simple Access 2003 application to keep track of things that need to be done for clients for some colleagues. Each colleague has a set of clients, and each client has a set of actions that need to be taken by a certain date. I've set up a form that consists of a combobox for client ID (indexed), a drop-down for the person who is handling that client's case, and a button for adding new clients (a standard Access-created Add Record button). The actions are listed in a subform below these three elements. The problem I've run into is that the first person I tested this on clicked the button to add a new record, then didn't fill it out and tried to select another client from the drop-down list. Access interprets this as an attempt to set the selected Client ID as the ID for the new record and rightfully throws an error for duplicate primary keys. I can think of a couple of ways around this problem, but I'd much rather hear your elegant solutions than kludge together some junk in a language I don't know. Let me know if you have any questions. Thank you.

  • How to setup and teardown temporary django db for unit testing?

    - by blokeley
    I would like to have a python module containing some unit tests that I can pass to hg bisect --command. The unit tests are testing some functionality of a django app, but I don't think I can use hg bisect --command manage.py test mytestapp because mytestapp would have to be enabled in settings.py, and the edits to settings.py would be clobbered when hg bisect updates the working directory. Therefore, I would like to know if something like the following is the best way to go: import functools, os, sys, unittest sys.path.append(path_to_myproject) os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings' def with_test_db(func): """Decorator to setup and teardown test db.""" @functools.wraps def wrapper(*args, **kwargs): try: # Set up temporary django db func(*args, **kwargs) finally: # Tear down temporary django db class TestCase(unittest.TestCase): @with_test_db def test(self): # Do some tests using the temporary django db self.fail('Mark this revision as bad.') if '__main__' == __name__: unittest.main() I should be most grateful if you could advise either: If there is a simpler way, perhaps subclassing django.test.TestCase but not editing settings.py or, if not; What the lines above that say "Set up temporary django db" and "Tear down temporary django db" should be?

  • WPF Drag-to-scroll doesn't work correctly.

    - by Garegin
    Hi all, I am tying to realize a drag-to-scroll functionality in my application and have problems on my way. Can anybody help me? I have a ScrollViewer and inside it an ItemsControl and within ItemsTemplate I have a UserControl. I want to drag that UserControl within ItemsControl. I want the ScrollViewer to scroll down, when I am dragging to the boundaries of the ItemsControl. protected override void OnPreviewMouseMove(System.Windows.Input.MouseEventArgs e) { if (this.IsMouseCaptured) { // Get the new mouse position. Point mouseDragCurrentPoint = e.GetPosition(this); if (Math.Abs(mouseDragCurrentPoint.Y - this.ActualHeight) <= 50) { this._scrollStartOffset.Y += 5; _containingScrollViewer.ScrollToVerticalOffset(this._scrollStartOffset.Y); } if (mouseDragCurrentPoint.Y <= 50) { this._scrollStartOffset.Y -= 5; _containingScrollViewer.ScrollToVerticalOffset(this._scrollStartOffset.Y); } } base.OnPreviewMouseMove(e); } When i start dragging by calling DragDrop.DoDragDrop() scrolling don't happens. But when i disable dragging, the ScrollViewer scrolls down dependong on mouse position. Maybe there's something that i don't take into accont about dragging and Capturing the mouse? Thanks for attention. Garegin

  • Detectig by how much user has scrolled

    - by Sean
    I have an image pop-up ability on my website (see this screenshot), in order to show users the full resolution picture when they click on a smaller version on the page. This is the current CSS that positions it: div#enlargedImgWrapper { position: absolute; top: 30px; left: 55px; z-index: 999; } The problem now is that if I click on an image further down the page, the window still appears in the top left corner of the page, where I can't see it until I scroll back up. I need it to appear relative to the window, whatever its current position relative to the document is. Note: I don't want to use position: fixed; as some images might be taller than the screen, so I want users to be able to scroll along the image as well. My idea was to use JS to change the top value: var scrollValue = ???; document.getElementById('enlargedImgWrapper').style.top = scrollValue+30 + 'px'; How can I detect by how much the user has scrolled down the page (var scrollValue)? Or is there a 'better' way to do this? Thanks!

  • Tiny MCE (jquery plugin version) not showing toolbar in IE (works fine in other browsers)

    - by I am Wonder
    I had an implementation working well but for some reason IE decided it was tired of playing nice. I have an advanced implementation of TinyMCE (the jquery plugin version - see http://tinymce.moxiecode.com/examples/example_23.php for details). It still works great in all browsers but IE. In IE it shows the drop-down options for Format, Font family, and Font size, but only as text.. not as a drop down normally looks. All other buttons on the toolbar are missing. (I've tried IE8 and IE8 Compatibility Mode) I get a javascript error: Syntax error Line 36 Char 1. Unfortunately the javascript is being loaded dynamically so this doesn't help me. Here is my implementation code for the TinyMCE editor: $(function () { $('#InputStuffHere').tinymce({ // General options theme: "advanced", plugins: "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,inlinepopups,preview,media,searchreplace,contextmenu,paste,fullscreen,noneditable,visualchars,nonbreaking,template", // Theme options theme_advanced_buttons1: "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,formatselect,fontselect,fontsizeselect,|,hr,removeformat", theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,image,|,forecolor,backcolor,|,spellchecker", theme_advanced_buttons3 : "", theme_advanced_toolbar_location: "top", theme_advanced_toolbar_align: "left", theme_advanced_statusbar_location: "bottom", theme_advanced_resizing: true, // Drop lists for link/image/media/template dialogs template_external_list_url: "lists/template_list.js", external_link_list_url: "lists/link_list.js", external_image_list_url: "lists/image_list.js", media_external_list_url: "lists/media_list.js", //initialization callback init_instance_callback: "TinyMCEReady", add_form_submit_trigger : false }); }); So... anyone seen anything like this or have any ideas for me? Thank you so much everyone!

  • How can I set the Jbuttons in a preferred order?

    - by Umzz Mo
    I have a grid of 30 buttons, and I want to have it from left to right then goes down, right to left, down again left to right. Basically the numbering would be as follow: 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 21 22 23 24 25 26 27 28 29 30 So if I have a piece on the button 10 and I instruct it to move up 2 bits it would land on 12 not 19. Below is my Code: //Creates the button using the loop, adds it into the panel and frame. JPanel panel = new JPanel(); panel.setLayout(new GridLayout(3,10)); JButton [] buttons = new JButton[30]; for(int i=0;i<30;i++){ buttons[i] = new JButton("label" + i); buttons[i].setBackground(Color.white); //Puts the player 1 piece on button 1,3,5,7,9 and player 2 piece on button 2,4,6,8,10 if (i < 10) { if (i%2 == 0) { buttons[i].setIcon(piece1); } else { buttons[i].setIcon(piece2); } } panel.add(buttons[i]); } frame.add(panel, BorderLayout.CENTER);

  • Using the AutoComplete feature of ComboBox, while limiting values to those in the list?

    - by Schmuli
    In WinForms 2.0, a ComboBox has an Auto-Complete feature, that displays a custom Drop-Down list with only the values that start with the entered text. However, if I want to limit valid values to only those that appear in the ComboBox's list of items, I can do that by setting the DropDownStyle to DropDownList, which stops the user from entering a value. However, now I can't use the Auto-Complete feature, which requires user input. Is there another way to limit input to the list, while still allowing use of the Auto-Complete feature? Note that I have seen some custom solutions for this, but I really like the way the matching Auto-Complete items are displayed in a Drop-Down list, and sorted even though the original list may not be. EDIT: I have thought about just validating the entered value, i.e. testing user input if it is valid in, say, the TextChanged event, or even using the Validating event. The question then is what is the expected behavior? Do I clear their value (an empty value is also invalid), or do I use a default value? Closest matching value? P.s. Is there any other tags that I could add to this question?

  • Iterate Through JSON Data for Specific Element - Similar to XPath

    - by Highroller
    I am working on an embedded system and my theory of the overall process follows this methodology: 1. Send a command to the back end asking for account information in JSON format. 2. The back end writes a JSON file with all accounts and associated information (there could be 0 to 16 accounts). 3. Here's where I get stuck - use JavaScript (we are using the JQuery library) to iterate through the returned information for a specific element (similar to XPath) and build an array based on the number of elements found to populate a drop-down box to select the account you want to view and then do stuff with the account info. So my code looks like this: loadAccounts = function() { $.getJSON('/info?q=voip.accounts[]', function(result) { var sipAcnts = $("#sipacnts"); $(sipAcnts).empty(); // empty the dropdown (if necessarry) // Get the 'label' element and stick it in an array // build the array and append it to the sipAcnts dropdown // use array index to ref the accounts info and do stuff with it } So what I need is the JSON version of XPath to build the array of voip.accounts.label. The first account info looks something like this: { "result_set": { "voip.accounts[0]": { "label": "Dispatch1", "enabled": true, "user": "1234", "name": "Jane Doe", "type": "sip", "sip": { "lots and lots of stuff": }, } } } Am I over complicating the issue? Any wisdom anyone could thrown down would be greatly appreciated.

  • Dealing with image upload on server

    - by user1073320
    I have got a the following problem: I have got multi-step form where in one step user upload image to server and then few steps further supplies other information, when this information is invalid no data should be commited - also the image should be deleted. I was thinking about PHP session, but I've read here PHP - Store Images in SESSION data? that it is inefficient way. Every time you proceed step in the form the image is reloaded (in the session) and as somebody mentioned "You will want it to only be as big as it needs to be and you need to delete it as soon as you don't need it because large pieces of information in the session will slow down the session startup." - here i got a question: will it slow down the stratup the session of user who upload file or sessions of all users? I have to mention that I'm looking for solution that doesn't rely on operating system scripts (cron or etc) - I have no permission to run such scripts. The perfect solution for me would be: saving image on disk (for example in some folder named after session id) then after the latest step of form move this image or delete depending on form validation. If user unexpectedly destroy the session (for example closing the browser) of course the folder with image should be deleted. In nutshell I need somethig like callback to event "destroying session".

  • Have a clickable button on top of a combobox in WPF

    - by Travyguy9
    I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

  • Flex: Scale an Image so that its width matches contentWidth?

    I have a dynamic layout, where an image is loaded into an HBox: <mx:HBox ...> <mx:Image height="100%" .../> </mx:HBox> only the image's height is set on the image, so that it can take all the vertical space available, while its width is left undefined and I expect the width to scale accordingly with its height. It turns out that the image's height is equal to its contentHeight, i.e. height scales properly; however, the image's width is still the same as measuredWidth (the image's original width), and is not scaled accordingly. For example, if the image's original size is 800x600 and if the HBox is 300 in height, then image height will scale down to 300, however its width doesn't scale down to 400, instead it stays at 800. I tried to add an event listener to explicitly set the image width: <mx:Image id="img" height="100%" updateComplete="img.width=img.contentWidth;" .../> It works only the first time the image is loaded, after that, if I use Image.load() to dynamically load different images, it stops working - the image width is set to 0. Any help/advice will be highly appreciated.

  • Codeigniter PHP - loading a view at an anchor point

    - by James Billings
    I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.
