  • set border for table with overflow is auto

    - by lucky
    Hi All, I would like to have a border for the table with class name as "wanttosetborder". Without the div it is setting border for this table. With the div tag, it is setting border till the last row before div tag,(i.e a line after H2 is displayed) after that no border is displayed. Please find the code below. <html> <head> <head> <style type="text/css"> #user{width: 50px;height:150px;overflow:auto;position:absolute} </style> </head> </head> <body> <TABLE class="wanttosetborder" CELLPADDING=1 cellspacing="1" border="1"> <tr><td>ABC</td></tr> <tr><td>H2</td></tr> <tr> <td> <div id="user"> <table> <?php for($i=1; $i<=10;$i++) { ?> <tr><td>123</td> </tr> <?php }?> </table> </div> </td> </tr> </TABLE> </body> </html>

  • Does running IIS7 in classic mode affect MVC output caching?

    - by Bob
    I have a need to run an application in classic mode for backwards compatibility with a specific application, and am trying to understand what kind of impact that will have on the performance of an MVC application that is running on the site. If we put a few static file maps (for .js, .css, .png, etc) above the ASP.NET wildcard map to reduce the amount of processing by the ASP.NET handler, will we be approaching the integrated mode in terms of performance? The thing i'm primarily concerned with is any effect this might have on output caching. I understand that integrated mode might (?) allow for the output cache to handle non ASP.NET content, but that isn't really a concern. We're more interested in ensuring that the MVC application has full use of the output cache. Empirically i've found that the two configurations operate on par when things go well, but if the page references resources that are not available, the integrated mode tends to fail much more quickly than the classic mode (e.g. 500 ms vs 10 seconds), reducing 'hang time' on the page load. Thanks for any feedback.

    - by Surya sasidhar
    hi, in my application i am using datalist to display the images, i put properties of repeatcolumn=4 and reapeatdirection=horizontal.

  • How can I bind another DependencyProperty to the IsChecked Property of a CheckBox?

    - by speedmetal
    Here's an example of what I'm trying to accomplish: <Window x:Class="CheckBoxBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel> <CheckBox Name="myCheckBox">this</CheckBox> <Grid> <Grid.Resources> <Style TargetType="ListBox"> <Style.Triggers> <Trigger Property="{Binding ElementName=myCheckBox, Path=IsChecked}" Value="True"> <Setter Property="Background" Value="Red" /> </Trigger> </Style.Triggers> </Style> </Grid.Resources> <ListBox> <ListBoxItem>item</ListBoxItem> <ListBoxItem>another</ListBoxItem> </ListBox> </Grid> </StackPanel> </Window> When I try to run it, I get this XamlParseException: A 'Binding' cannot be set on the 'Property' property of type 'Trigger'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject. So how can I bind a property on the ListBox to the IsChecked property of a CheckBox?

  • Angular ng-style not changing with property

    - by ganaraj
    For the life of me I cant seem to figure out why the style property is not getting updated. In my larger application it seems to work fine. http://jsfiddle.net/ganarajpr/C2hRa/4/ Here is a fiddle which shows the issue I am currently facing. You will notice that the width and height are getting updated in the div when you change the input. But the style itself doesnt seem to be updating. Anyone can tell me what I am doing wrong here? I have tried all the following scenarios using $scope.$apply.. - Throws an error stating $apply already in progress.. $rootScope.$apply - same as above. Setting another variable in a service which is $watched in the other controller. - no change seen. It would be really cool if someone can get me an answer to this. Also would be really happy if you can tell me why exactly it is not getting updated.

  • Questions about serving static files from a servlet

    - by Geo
    I'm very new to servlets. I'd like to serve some static files, some css and some javascript. Here's what I got so far: in web.xml: <servlet> <description></description> <display-name>StaticServlet</display-name> <servlet-name>StaticServlet</servlet-name> <servlet-class>StaticServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>StaticServlet</servlet-name> <url-pattern>/static/*</url-pattern> </servlet-mapping> I'm assuming in the StaticServlet I'd have to work with request.getPathInfo to see what was requested, get a mime type, read the file & write it to the client. If this is not the way to go, or is not a viable way of doing things, please suggest a better way. I'm not really sure where to place the static directory, because if I try to print new File(".") it gives me the directory of my Eclipse installation. Is there a way to find out the project's directory?

  • jQuery .trigger() or $(window) not working in Google Chrome

    - by Jonathan
    I have this jQuery ajax navigation tabs plugin that I created using some help from CSS-Tricks.com and the jQuery hashchange event plugin (detects hash changes in browsers that don't support it). The code is little long to post it here but it goes something like this: Part 1) When a tab is clicked, it gets the href attribute of that tab and add it to the browsers navigation bar like '#tab_name': window.location.hash = $(this).attr("href"); Part 2) When the navigation bar changes (hash change), it gets the href change like this: window.location.hash.substring(1); (substring is to get only 'tab_name' without the '#'), and then call the ajax function to get the info to display. I want to automatically trigger the plugin to load the first tab when the page is accessed, so at the start of the code I put: if (window.location.hash === '') { // If no '#' is in the browser navigation bar window.location.hash = '#tab_1'; // Add #tab_1 to the navigation bar $(window).trigger('hashchange'); // Trigger a hashchange so 'Part 2' of the plugin calls the ajax function using the '#tab_1' added } The probles is that it works in FF but not in Chrome, I mean, everything works but it seems like the $(window).trigger('hashchange'); is not working because it doesnt get the first tab.. Any suggestions??

  • jQueryUI Modal confirmation dialog on form submission

    - by DavidYell
    I am trying to get a modal confirmation dialog working when a user submits a form. My approach, I thought logically, would be to catch the form submission. My code is as follows, $('#multi-dialog-confirm').dialog({ autoOpen: false, height: 200, modal: true, resizable: false, buttons: { 'Confirm': function(){ //$(this).dialog('close'); return true; }, 'Cancel': function(){ $(this).dialog('close'); return false; } } }); $('#completeform').submit(function(e){ e.preventDefault(); var n = $('#completeform input:checked').length; if(n == 0){ alert("Please check the item and mark as complete"); return false; }else{ var q = $('#completeform #qty').html(); if(q > 1){ $('#multi-dialog-confirm').dialog('open'); } } //return false; }); So I'm setting up my dialog first. This is because I'm pretty certain that the scope of the dialog needs to be at the same level as the function which calls it. However, the issue is that when you click 'Confirm' nothing happens. The submit action does not continue. I've tried $('#completeform').submit(); also, which doesn't seem to work. I have tried removing the .preventDefault() to ensure that the form submission isn't completely cancelled, but it doesn't seem to make a difference between that and returning false. Not checking the box, show and alert fine. Might change to dialog at some point ;), clicking 'Cancel' closes the dialog and remains on the page, but the elusive 'Confirm' buttons seems to not continue with the form submission event. If anyone can help, I'd happily share my lunch with you! ;)

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • Convert Google Analytics cookies to Local/Session Storage

    - by David Murdoch
    Google Analytics sets 4 cookies that will be sent with all requests to that domain (and ofset its subdomains). From what I can tell no server actually uses them directly; they're only sent with __utm.gif as a query param. Now, obviously Google Analytics reads, writes and acts on their values and they will need to be available to the GA tracking script. So, what I am wondering is if it is possible to: rewrite the __utm* cookies to local storage after ga.js has written them delete them after ga.js has run rewrite the cookies FROM local storage back to cookie form right before ga.js reads them start over Or, monkey patch ga.js to use local storage before it begins the cookie read/write part. Obviously if we are going so far out of the way to remove the __utm* cookies we'll want to also use the Async variant of Analytics. I'm guessing the down vote was because I didn't ask a question. DOH! My questions are: Can it be done as described above? If so, why hasn't it been done? I have a default HTML/CSS/JS boilerplate template that passes YSlow, PageSpeed, and Chrome's Audit with near perfect scores. I'm really looking for a way to squeeze those remaining cookie bytes from Google Analytics in browsers that support local storage.

  • Silverlight 4 ComboBox - Binding to Nullable data (tried TargetNullValue but not working as expected)

    - by Laurence
    (Please note - I am a Silverlight beginner and am looking for the simplest solution here, e.g. that doesn't involve writing/installing a replacement for the ComboBox control!) This is an issue with a Silverlight 4 application that uses the View Model (MVVM) approach. I have a simple form for editing a "Product" object. Product has a CategoryID property which is nullable (int?). A ComboBox is used to view and set the CategoryID - this is bound to an ObservableCollection of Categories. Product also has number of non-nullable properties bound to TextBoxes. I want the user to see "N/A" in the ComboBox for a product with no category, and to be use this "N/A" option to set CategoryID to null. So, I manually added a Category object with CategoryID=0 and CategoryName="N/A" to the collection; then I set TargetNullValue=0 in the SelectedValue Binding of the ComboBox. My thinking was - when the ComboBox SelectedValue was bound to a null CategoryID it would substitute zero, and therefore select the "N/A" option. When editing a Product with a non-null CategoryID, everything works. However when a null CategoryID is found, two problems occur: No option is selected in the ComboBox (its blank) The ComboBox binding seems broken from this point onwards - any Product I subsequently edit (incl. ones with a non-null CategoryID) have nothing selected in the ComboBox (its still populated with all categories - just no selected item). I've seen reports of problem #2 (here, here) but I was under the impression that #1 should have worked. What am I missing to get the "N/A" option to be selected? XAML for ComboBox: <ComboBox x:Name="cboCategory" ItemsSource="{Binding colCategories, Mode=OneWay}" SelectedValuePath="CategoryID" DisplayMemberPath="CategoryName" SelectedValue="{Binding CurrentProduct.CategoryID, Mode=TwoWay, TargetNullValue=0}" Height="24" Width="344"></ComboBox>

  • JQuery Dragging Outside Parent

    - by Andy
    I'm using JQuery's draggable(); to make li elements draggable. The only problem is when the element is dragged outside its parent, it doesn't show up. That is, it doesn't leave the confines of its parent div. An example is here: http://imgur.com/N2N1L.png - it's as if the z-index for everything else has greater priority (and the element slides under everything). Here's the code: $('.photoList li').draggable({ distance: 20, snap: theVoteBar, revert: true, containment: 'document' }); And the li elements are placed in DIVs like this: <div class="coda-slider preload" id="coda-slider-1"> <div class="panel"> <div class="panel-wrapper"> <h2 class="title" style="display:none;">Page 1</h2> <ul class="photoList"> <li> <img class="ui-widget-content" src="photos/1.jpg" style="width:100px;height:100px;" /> </li> </ul> </div> </div> I'm positive the problem is it won't leave its parent container, but I'm not sure what to do to get it out. Any direction or help would be appreciated GREATLY!

  • Silverlight 3: ListBox DataTemplate HorizontalAlignment

    - by Lee
    I have a ListBox with it's ItemTemplate bound to a DataTemplate. My problem is I cannot get the elements in the template to stretch to the full width of the ListBox. <ListBox x:Name="listPeople" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,0,0,0" Background="{x:Null}" SelectionMode="Extended" Grid.Row="1" ItemTemplate="{StaticResource PersonViewModel.BrowserDataTemplate}" ItemsSource="{Binding Mode=OneWay, Path=SearchResults}" > </ListBox> <DataTemplate x:Key="PersonViewModel.BrowserDataTemplate"> <ListBoxItem HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,5,5"> <Border Opacity=".1" x:Name="itemBorder" Background="#FF000000" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CornerRadius="5,5,5,5" MinWidth="100" Height="50"/> </Grid> </ListBoxItem> </DataTemplate> As you can see, I have added a border within the grid to indicate the width of the template. My goal is to see this border expand to the full width of the listbox. Currently its width is determined by its contents or MinWidth, which is the only thing at the moment keeping it visible at all.

  • Javascript iframe caching issue

    - by Brian
    I hava an iframe which loads some javascript via javascript. In internet explorer only, this works if and only if IE has a cached copy of the javascript. This means that reloading the page (or otherwise triggering the script to run again, if it's stuck in a function or whatever) will cause this code to work, otherwise it will not. In particular, the document.write call fails to happen. Main Page: <iframe height = "200" width = "200" id = "happy"> </iframe> <script type="text/javascript"> var a = document.getElementById("happy"); scripttxt = '<a href="#" id="joy">JOY</a><'+'script type="text/javascript" src="fail.js"></'+'script>'; a.src = "about:blank"; a.contentWindow.document.open(); a.contentWindow.document.write("<h3>Preview:</h3>" + scripttxt + ""); a.contentWindow.document.close(); </script> fail.js: document.write(document.getElementById("joy")); I realize I could use conditional comments to have IE skip document.open() and document.close() in the script of Main Page, but having IE skip document.open() and document.close() feels a bit hacky (Edit)...and breaks other things in IE.

  • IE8 claims my page has an error, firefox doesn't, and I can't find any error. Help!

    - by Bears will eat you
    This is something of a follow-up question to my question here. You can find the HTML source in a text file here. When I load that page in IE8, I get the "Done, but with errors on page." message in my status bar. The detail view shows Expected identifier sms Line: 147 Code: 0 Char: 67 and I see absolutely no problems anywhere near there. In IE8, the page is still behaving erratically w/r/t the randomly losing focus as mentioned in my other question. When I load the same exact page in Firefox (using Firebug) the console shows no errors and the page works perfectly. Any thoughts on what's going on here? This is driving me nuts and making me want to give up on even trying to write an IE friendly page. Edit: Thanks for all the comments! This page is written as a JSP, so I edit in Eclipse. I found an Eclipse warning about the onblur event for the username field. I switched it from onblur="alert(document.activeElement + ' class:' + document.activeElement.class)" to onblur="alert(document.activeElement)" and that made the bizarre IE page error vanish. I had been trying to give more info (namely, its CSS class) about specifically which element is stealing focus - to my own detriment, apparently, since Javascript was interpreting the '.class' part in the Java(script) sense. And, no, the page doesn't validate. But the errors were mostly/all ones that just didn't make sense, such as Line 14, Column 41: Attribute "LANGUAGE" is not a valid attribute. Did you mean "language"? to which I say, WTF?! But I'm still stuck trying to figure out why, as I enter text in the username & password fields, focus randomly switches to a div (working on figuring out which div currently). Edit 2: It's the div between the two "global nav" comments, at the very top of the body. Still no idea why it's happening, though.

    - by Brian Ensink
    I have a WPF UserControl. The code behind file declares some RoutedUICommand objects which are referenced in the XAML. The application builds and runs just fine. However Expression Blend 3 cannot load the XAML in the designer and gives errors like this one: The member "ResetCameraCommand" is not recognized or accessible. The class and the member are both public. Building and rebuilding the project in Blend and restarting Blend hasn't helped. Any ideas what the problem is? Here are fragments of my XAML ... <UserControl x:Class="CAP.Visual.CameraAndLightingControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CAP.Visual;assembly=VisualApp" Height="100" Width="700"> <UserControl.CommandBindings> <CommandBinding Command="local:CameraAndLightingControl.ResetCameraCommand" Executed="ResetCamera_Executed" CanExecute="ResetCamera_CanExecute"/> </UserControl.CommandBindings> .... ... and the code behind C# namespace CAP.Visual { public partial class CameraAndLightingControl : UserControl { public readonly static RoutedUICommand ResetCameraCommand; static CameraAndLightingControl() { ResetCameraCommand = new RoutedUICommand("Reset Camera", "ResetCamera", typeof(CameraAndLightingControl)); }

  • stackoverflow tags and related tags

    - by parminder
    Hi Experts, I am working on a website where a user can add tags to their posted books. It is similar to stackover flow, but I am keeping my tags in differnt table. so here are the tables/class in linq to entities. Books { bookId, Title } Tags { Id Tag } BooksTags { Id BookId TagId } Here are few sample records. Books BookId Title 113421 A 113422 B Tags Id Tag 1 ASP 2 C# 3 CSS 4 VB 5 VB.NET 6 PHP 7 java 8 pascal BooksTags Id BookId TagId 1 113421 1 2 113421 2 3 113421 3 4 113421 4 5 113422 1 6 113422 4 7 113422 8 Question 1 : I need to write something in linq to entities queries which gives me data according to the tags say if I want bookIds where tagid =1 it should return bookid 113421 and 113422 as it exists in both the books, but If I ask data for tags 1 and 2 it should return only book 113421 as that is the only book where both the tags are present. Question 2 : I need tags and their count too to show in related tags, so in first case my related tags class should have following result. RelatedTags Tag Count 2 1 3 1 4 2 8 1 in the second case when two tags are requested the result should be like RelatedTags Tag Count 3 1 4 1 I have get the first thing working by converting a sql query in linqer, but that seems like a hell. so want to know if there is any better idea. I have used dyanmic where clause to include two tags. So if someone can help. It will be much appreciated. Thanks Parminder

  • How To Share Information Between Django and Javascript?

    - by Randy
    So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

  • Concatenating a string and byte array in to unmanaged memory.

    - by Scott Chamberlain
    This is a followup to my last question. I now have a byte[] of values for my bitmap image. Eventually I will be passing a string to the print spooler of the format String.Format("GW{0},{1},{2},{3},", X, Y, stride, _Bitmap.Height) + my binary data; I am using the SendBytesToPrinter command from here. Here is my code so far to send it to the printer public static bool SendStringPlusByteBlockToPrinter(string szPrinterName, string szString, byte[] bytes) { IntPtr pBytes; Int32 dwCount; // How many characters are in the string? dwCount = szString.Length; // Assume that the printer is expecting ANSI text, and then convert // the string to ANSI text. pBytes = Marshal.StringToCoTaskMemAnsi(szString); pBytes = Marshal.ReAllocCoTaskMem(pBytes, szString.Length + bytes.Length); Marshal.Copy(bytes,0, SOMTHING GOES HERE,bytes.Length); // this is the problem line // Send the converted ANSI string + the concatenated bytes to the printer. SendBytesToPrinter(szPrinterName, pBytes, dwCount); Marshal.FreeCoTaskMem(pBytes); return true; } My issue is I do not know how to make my data appended on to the end of the string. Any help would be greatly appreciated, and if I am doing this totally wrong I am fine in going a entirely different way (for example somehow getting the binary data concatenated on to the string before the move to unmanaged space. P.S. As a second question, will ReAllocCoTaskMem move the data that is sitting in it before the call to the new location?

  • Javascript/Canvas/Images scaling problem in Firefox

    - by DocTiger
    I have a problem with the context2d's drawImage function. Whenever I scale an image, it gets a dark border of one pixel, which is kind of ugly. That does only happen in Firefox, not in Opera or Webkit. Is this an antialiasing problem? For hours I studied the examples and available documentation without getting rid of it... I couldn't yet try it on another computer so maybe just maybe it's an issue with the graphics hardware/drivers. I have reproduced this effect with this minimal snippet, assuming exp.jpg is sized 200x200 pixels. <html> <body> <canvas id="canvas" width="400" height="400"></canvas> </body> <script type="text/javascript" src="../../media/pinax/js/jquery-1.3.2.min.js"></script> <script type="text/javascript" > context = $('#canvas')[0].getContext('2d'); img = new Image(); img.src = "exp.jpg"; //while (!img.complete); context.drawImage(img, 2,2,199,199); context.drawImage(img, 199,2,199,199); </script> </html>
