  • Django/Python: Save an HTML table to Excel

    - by kchau
    I have an HTML table that I'd like to be able to export to an Excel file. I already have an option to export the table into an IQY file, but I'd prefer something that didn't allow the user to refresh the data via Excel. I just want a feature that takes a snapshot of the table at the time the user clicks the link/button. I'd prefer it if the feature was a link/button on the HTML page that allows the user to save the query results displayed in the table. Is there a way to do this at all? Or, something I can modify with the IQY? I can try to provide more details if needed. Thanks in advance.

  • When Does the File Download Dialog Open? - HTML, Javascript

    - by sahs-i-muhterem
    Hello, I have a html page, and when I click a file link on the page, the file download dialog pops up, and this file dialog locks the page. I mean without selecting one of the choices(Open, Save, Cancel) I can't do anything on the page (which is normal). What I need is if javascript can check whether the page is locked or not. (or whether the file dialog is popped?) p.s. don't say "put an onclick event to the link", because the server may respond very slowly (like 30 seconds after clicking)

What i want to know how to show content(mysql) inside a div when you click on a link. There will be 8-10 links and clicking on each should fetch its corresponding products.

  • Problem with files consists of spaces and single quotes?

    - by Vijay
    I'using the following code to create thumbnails using ffmpeg but it was working fine for the files which have no spaces or any quotes.. But when the file has a space (like 'sachin knock.flv') or files which have quotes (like sachin's_double_cent.mp4) it doesn't work.. What can i do to get those files work accurately? One restriction is that i can't rename files as they are lump some.. My code is <?php error_reporting(E_ALL); extension_loaded('ffmpeg') or die('Error in loading ffmpeg'); $link = mysql_connect('localhost', 'root', ''); if (!$link) { die('Not connected : ' . mysql_error()); } $db_selected = mysql_select_db('db', $link); $max_width = 120; $max_height = 72; $path ="/home/rootuser/public_html/temp/"; $qry="select id, input_file, output_file from videos where thumbnail='' or thumbnail is null;"; $res=mysql_query($qry); while($row = mysql_fetch_array($res,MYSQL_ASSOC)) { $orig_str = array(" "); $rep_str = array("\ "); $outfile = $row[output_file]; // $infile = $row[input_file]; $infile1 = str_replace($orig_str, $rep_str, $outfile); $tmp = explode(".",$infile1); $tmp_name = $tmp[0]; $imgname = $tmp_name.".png"; $srcfile = "/home/rootuser/public_html/uploaded_vids/".$outfile; echo exec("ffmpeg -i ".$srcfile." -r 1 -ss 00:00:05 -f image2 -s 120x72 ".$path.$imgname); $nname = "./temp/".$imgname; $fileo = fopen($nname,"rb"); if($fileo) { $imgData = addslashes(file_get_contents($nname)); echo $imgdata; $qryy="update videos set thumbnail='{$imgData}' where input_file='$outfile'"; $ress=mysql_query($qryy); } else echo "Could not open<br><br>"; unlink('$nname'); } ?>

  • JSF 2.0: Preserving component state across multiple views

    - by tlind
    The web application I am developing using MyFaces 2.0.3 / PrimeFaces 2.2RC2 is divided into a content and a navigation area. In the navigation area, which is included into multiple pages using templating (i.e. <ui:define>), there are some widgets (e.g. a navigation tree, collapsible panels etc.) of which I want to preserve the component state across views. For example, let's say I am on the home page. When I navigate to a product details page by clicking on a product in the navigation tree, my Java code triggers a redirect using navigationHandler.handleNavigation(context, null, "/detailspage.jsf?faces-redirect=true") Another way of getting to that details page would be by directly clicking on a product teaser that is shown on the home page. The corresponding <h:link> would lead us to the details page. In both cases, the expansion state of my navigation tree (a PrimeFaces tree component) and my collapsible panels is lost. I understand this is because the redirect / h:link results in the creation of a new view. What is the best way of dealing with this? I am already using MyFaces Orchestra in my project along with its conversation scope, but I am not sure if this is of any help here (since I'd have to bind the expansion/collapsed state of the widgets to a backing bean... but as far as I know, this is not possible). Is there a way of telling JSF which component states to propagate to the next view, assuming that the same component exists in that view? I guess I could need a pointer into the right direction here. Thanks! Update 1: I just tried binding the panels and the tree to a session-scoped bean, but this seems to have no effect. Also, I guess I would have to bind all child components (if any) manually, so this doesn't seem like the way to go. Update 2: Binding UI components to non-request scoped beans is not a good idea (see link I posted in a comment below). If there is no easier approach, I might have to proceed as follows: When a panel is collapsed or the tree is expanded, save the current state in a session-scoped backing bean (!= the UI component itself) The components' states are stored in a map. The map key is the component's (hopefully) unique, relative ID. I cannot use the whole absolute component path here, since the IDs of the parent naming containers might change if the view changes, assuming these IDs are generated programmatically. As soon as a new view gets constructed, retrieve the components' states from the map and apply them to the components. For example, in case of the panels, I can set the collapsed attribute to a value retrieved from my session-scoped backing bean.

  • Browser back button broken between hidden div's

    - by Linda
    First of all, these pages will never be on the web but will be in internal memory. They are a group of linked documents---an ebook. http://www.anmldr.com/testdivs When I click on the link in the first div, the second div becomes visible and the first div is hidden. The problem is with the browser's back button. If you then click on the back button, the URL updates but the first div does not show again. How can I correct the back button so that the first div shows? The link from the second div to the first div works fine but it is the browser back button that I do not know how to work with. Thanks, Linda P.S. These are using CSS3 so it is better to use a WebKit based browser.

  • CSS for mobile sometimes reverts back to original

    - by Jessie
    So most of the time my stylesheets appear properly. The standard/original one always works flawlessly, however it seems sometimes the mobile one is disregarded when looked at from a mobile device I have them designated as follows: <link runat="server" href="CustomStyleSheets/Menu.css" rel="stylesheet" type="text/css" /> <link href="CustomStyleSheets/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 799px)" /> I'm using a Droid X to view the page, in portrait mode, so the device width shouldn't be exceeding the max-width specified above, but sometimes, randomly, it still reverts back to the original css page. Any way to keep it from doing so?

  • How can one put together multiple arrays into one string?

    - by Noor
    I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

  • PHP regular expression

    - by Ferol
    such text: $text = ' href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; // $text = ' text... <a href="http://yahoo.com" target="_blank"> link text </a> text... text... <br> text...'; and such regular expression: preg_match_all('/^(.*)(<.+>)(.*)(<\/.+>)(.*)$/',$text,$matches); what I want, - to check if text matches the regular expression. If yes, then $matches should contain parts of string above, if not (as I guess) it should contain four zero-length arrays. something is wrong, but I can't find, what actually is?

    - by madmik3
    I'm trying to link to a static library and I keep getting linker errors. I've found a few sites that post examples but I have not been able to see what I am doing wrong. First I create a project that will link to my lib add existing files find my .xcodeproj file select "Copy items into destination groups folder"... Select my host project as Add To Targets. Then I add a direct dependency to my host app expand targets double click MyHost.app click + under direct dependencies select my lib Then I set build flags double click MyHost application icon in Groups and Files. click the build tab then I set the OtherLinerFlag to -ObjC then I set Header Search Paths to my header file location for my static library. I pass the compile stage but any classes in my static lib cause linker error: literal-pointer@_OBJC@_cls_refs@SomeClass in MyHost.o thanks!

  • Win32 Window Menu is appearing along left side instead of across top of window

    - by Khat
    I think I may be using a wrong window style or something or maybe just adding the menu to the window incorrectly. I'll post a link to an image here so you can see what I mean about the menu not diplaying correctly: http://img707.imageshack.us/img707/4828/wtfmenu.jpg And here's a link to the code that creates the menu and the window: http://pastebin.com/CBrSVXUD I'm sure I'm missing something simple and dumb in the labyrinth of styles, settings and etc that are part and parcel for the Win32 API. Has anyone seen this before and know what I'm doing wrong? I just want a 'normal' menu bar along the top, snug against the title bar. Thanks in advance for any advice.

  • Rails - Ability to Enable/Disable Links on a View?

    - by AnApprentice
    Hello, I have a UserMailer View that has several link_to's like so: <%= link_to('XXXXXXXX Link Title', item_url(@item, :only_path => false), :style => 'color:#5196E3;text-decoration:underline;') %> The page has several different links. I'd like to know if there is a way to globally set in the view to enable or disable the links. If enabled, the above would run like normal, if not the block above would just show the text (XXXXXXXX Link Title) and not be linked? Any ideas other than wrapping every link_to inside a IF statement? Thanks

  • Encrypt URL in asp.net

    - by Zerotoinfinite
    Hi All, My site is in asp.net 3.5 and C#. I am sending link to my user through mail, now I want to send each user a specific URL. so instead of sending the clear text I want to send link with encrypted string URL, which I will decrypt on my home page. Like instead of www.mysite.aspx\mypage?userId=12 i'll send www.mysite.aspx\mypage?UserId=)@kasd12 and the same i'll decrypt on my page so that I'll get the userId = 12. Please let me know if my approach is correct and not and how can I encrypt & decrypt the string in simplest and easier manner. Thanks in advance.

  • How to set the content of the $script_for_layout in cakephp?

    - by sipiatti
    Hi, I am learning cakephp in an autodidact manner and I am a complete newbie :) I am creating a simple application. Some logic work so now I going to dive into designing views and layouts. I read the docs and the tutorial but I could not find where to set the content of $script_for_layout. Especially I want to set a $html-css to create link in pages to the stylesheet. I found out that I could do it in directly in the layout template but I would like to create the same link in all pages/views/layouts to the stylesheet so I hope there is a simple way, and avoid to do this in all layouts and/or controllers

  • Rails: common approach for handling exceptions in restful actions on objects that have been destroye

    - by Greg
    It is very common in Rails for an objects_controller controller to have RESTful edit and destroy actions like so: def edit @object = Object.find(params[:id]) end def destroy @object = Object.find(params[:id]) @object.destroy redirect_to :back end With an associated view that provides edit and destroy links like so: <%= link_to "Edit the Object", edit_object_path(object) %> <%= link_to "Delete", object, :confirm => 'Are you sure?', :method => :delete %> And it is easy to blow this up. If I open two browser windows, A and B, destroy an object with the "Delete" link in browser A and then press the "Edit" link in browser B, the find() in the edit action throws an exception. Obviously there are several ways to deal with this in the edit action: catch the exception and recover gracefully use @object = find(:first, "conditions... etc. and test the @object before going further But seeing as this is such a common pattern, I would love to know how other folks deal with this situation.

  • HTTPS and FormAssembly

    - by Mark
    We are using a FormAssembly page to collect feedback - it's hosted within an IFrame on the side of our site's master page. The thing is, that some parts of our site are HTTPS - viewing and posting the form is ok in HTTPS, but the problem comes with the "thank you" page - we are using the configurable custom thank you page (configured within FormAssembly iteself). Is there are way we can send the desired response page up (perhaps via a hidden field within the posted form?) - this way we can send the HTTPS link for the HTTPS version of the form and the normal HTTP link for the HTTP form? Thanks!
