• Ubuntu installation does not recognize previous partitions

  - by Hawkcannon

  I have been attempting to install Ubuntu (10.04, Lucid Lynx) on my computer. I wasn't ready to take the pure-Linux plunge yet, so I reserved a partition on which I would install Ubuntu. I ran the installer and answered the 'minor' questions (keyboard layout, time zone, etc.), but had trouble when I reached the partitioning. I have several partitions, but Ubuntu only saw one of them, which was not the ext3 partition that I had set up. I tried deleting the partition in hope that the installer would find and utilize the empty space, but it only saw the original partition. I do not have an external hard drive to use, and I cannot clear any existing partitions. Am I running the installer incorrectly, or is there a more serious problem?

• Generate PDF - how to create paged HTML content beforehand?

  - by Alt_Doru

  My task is to create ready-to-print invoices from a .NET web app. I am already generating the printer-friendly HTML for an invoice - it consists of an invoice header (that will actually need to appear on each printed page) and invoice positions (that may span multiple printed pages). Now, my task is to generate a PDF server-side, populate a header on each of its pages, then populate its pages with invoice positions. I need to generate the PDF from the existing HTML data - by simply passing HTML input to the PDF generator library. I've started using ABCPDF - I am using the AddImageHtml method. The problem I have is that ABCPDF seems to expect me to supply HTML content already paged. So, it won't work correctly when I feed it HTML content that would span on more than 1 PDF page. So, my question is - do you have any suggestions on making this work with ABCPDF? Or, more generally speaking, what other tools/approaches would you use for this - generating PDF doc with headers/footers from HTML input? Thanks

• Can't get to Pex download (or visual studio 2010)

  - by Vaccano

  I know this is probably not a "True" stackoverflow question, but here it is anyway: Is anyone able to get to the MSDN Download of Visual Studio 2010? I just get "Your search did not match any products." when I click on the New Downloads-Visual Studio 2010 link. I was able to download Visual Studio on Monday. But it is gone now. That is not really my issue though. That page is also where the pex download is. With that page down I can't download pex either. (I checked with a co-worker (who is having the same issue) before posting. So I know it is not just me.)

• Is it ever a bad idea to publish a sitemap for a blog?

  - by mipadi

  I have a blog, and I have been considering publishing a sitemap for it, which would include the index page, archives page, and an entry for each individual blog post. Is this ever a bad idea? Is it a good (or useful) idea? I'm particularly interested in the <changefreq> element: I edit posts from time to time, and while that's not a common occurrence, I don't want to set a particularly infrequent change frequency that prevents search engines like Google from indexing the edits. (The sitemaps protocol says that search engines may still crawl the pages more frequently, but has no further details on the matter.)

• Javascript/jQuery height calculation

  - by danit

  Im looking for a way, in javascript, to calculate the size of the browser (px) then calculate the size of a <div> taking away 50px from that full screen size: E.g. Browser screen size: 800px (Height) Existing <div> that is always 50px (Height) Leaves 750px (Height) for the remaining <div> to fill the page. Then take that 750px and apply it as inline style: <div style="height: 50px"> <img src="banner.png" /> </div> <div style="height: x"> This fills the remainder of the page </div>

• Wordpress: Create a customized role / user

  - by Mestika

  Hi, I’m farely new to Wordpress but are working on putting a page together which has a very simple purpose. I’m creating it for a customer with little or none IT experience so I want to create a user he can use to login and edit his pages – and nothing more. No settings, no comments, no posts, no links, no nothing, just create, delete and edit pages and maybe edit his own profile or at least his E-mail and password. I can see that wordpress has some predefined roles for users but none of them completely does what I want and they either has to little or to many rights. I’ve been looking at the wordpress page http://codex.wordpress.org/Roles_and_Capabilities but can’t seem to get a clear answer. Is it in any way possible for me to create my own user role (e.g. customer) where I can set the rights I want for him? Thanks Sincerely Mestika

• multiple partial views mvc 2

  - by nik1

  Hello World! Hi guys, I have a master page with two partial viewson it both of which submit to the AccountController. When I click Submit on either of the partial views the following happens: If I declare the partial views like Html.BeginForm("PartialAction1","Account") it redirects to that partial view on clicking submit instead bringing back the default HomeContoller Index view with validation errors. If I declare the partial view forms as Html.BeginForm() then it returns to the default index view of the home controller. But it actually fires both partial view actions inside the AccountController and thus returns validation errors for both partial views simultaneously. What I want is version 2 above with only one action firing instead of two. Am I missing, hopefully, something very simple? I hoping someone can help me or point me in the right direction. Here's the code from my master page for the partial views Html.Action("Login1","Account") Html.Action("Login2", "Account") Many Thanks!

• How to include javascript/css once with Struts 1.x

  - by Felix

  If this is the wrong approach, please suggest something better, but my current efforts have been trying to find something that exists for a single page load, such that I can cache which javascript/css files have been included so as to only include them once. I thought in a TagSupport subclass I could use (HttpServletRequest)pageContext.getRequest().getParameterMap().put(srcKey,true) but the request is per jsp, not per page load so it was a failure. I could set up a filter in web.xml, but it seems I would have to search the response for duplicates and rewrite the response...pain. I could try to store things in the session, but there are headaches with clearing values... Any help would be appreciated.

• Help creating image from LVM

  - by jackhab

  I need to duplicate CentOS hard drive image for multiple stations. The HD has the following layout: Disk /dev/sdb: 250GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 250GB 250GB primary lvm I saved /dev/sdb1 to file with fsarchiver but for sdb2 I get: /fsarchiver savefs an2.fsa /dev/sdb2 oper_save.c#1006,filesystem_mount_partition(): can't detect and mount filesystem of partition [/dev/sdb2], cannot continue. removed an2.fsa Although fsarchiver probe simple correctly detects sdb2 as LVM2_member. Is fsarchiver correct tool for this job? What's wrong? I'm on Ubuntu 9.1 with fsarchiver 0.6.8 and lvm tools installed. Thanks.

• jQuery jScrollPane - it simply won't work! :'(

  - by Jack Webb-Heller

  Hey folks, OK - I'll admit, I'm quite a beginner in this jQuery-department. I've probably made some amateur mistake, but hey, you gotta learn somewhere! :) So I'm using jScrollPane: http://www.kelvinluck.com/assets/jquery/jScrollPane/jScrollPane.html I want to use it style the scrollable area in my second column. Specifically, I would like to apply and format the scrollbars on the div #ajaxresults My page is... rather jQuery heavy. I don't know if any variables are conflicting or something... in fact I really have no idea at all why this isn't working. Take a look at my problematic page: http://furnace.howcode.com In the header, I've set this to go: <!-- Includes for jScrollPane --> <script type="text/javascript" src="http://localhost:8888/js/jquery.mousewheel.min.js"></script> <script type="text/javascript" src="http://localhost:8888/js/jScrollPane.js"></script> <link rel="stylesheet" type="text/css" media="all" href="http://localhost:8888/stylesheets/jScrollPane.css" /> <script type="text/javascript"> $(function() { $('#ajaxresults').jScrollPane(); }); </script> (I've changed localhost on the server copy though) Nothing ever seems to work with the #ajaxresults div. I've set, as the jScrollPane docs say, overflow:auto on it but still no luck. I find that when jScrollPane DOES seem to 'run' it just moves the div down about 100 pixels. Try it for yourself. Perhaps someone could help? There's quite a few jQuery plugins there so I don't know if something's colliding/crashing etc... Please note the site is still in development between myself and a friend, which explains the personal messages we submit to each other ('Hi Donnie!' etc. :D ). Also, when you view the page nothing may appear in the second column for a few seconds - it's just fetching the data via Ajax. So give it a little time. Thanks very much! Jack

• Javascript library to reliably delay-load java applets

  - by paleozogt

  I'd like to delay-load a Java Applet in the same way that SwfObject loads Flash SWFs-- you supply it a div id and it replaces the div's contents. This would allow the whole page to load before the Applet starts. However, I'd also like to use a best-practices Javascript library like deployJava.js or applet-fu. The problem with these libraries is that they only use document.writeln-- if you use them after the DOM loads they will clobber the page. Are there any Applet-loading JavaScript libraries that allow for delay-loading?

• Problem with Efficient Gridview paging without datasource control

  - by Ronnie Overby

  I am trying to do efficient paging with a gridview without using a datasource control. By efficient, I mean I only retrieve the records that I intend to show. I am trying to use the PagerTemplate to build my pager functionality. In short, the problem is that if I bind only the records that I intend to show on the current page, the gridview doesn't render its pager template, so I don't get the paging controls. It's almost as if I MUST bind more records than I intend to show on a given page, which is not something I want to do.

• Dojo load time extremely slow on iis

  - by Josh

  I am currently working on a project that is using Dojo as the js framework. Its a rather rich ui and as such is using (and thus loading) a lot of different .js files for the dojo plug-ins When run on an apache server running on a mac, the files (all around 1k) are served very quickly (1 or 2 ms) and the page loads pretty fast (<5 seconds) When run on IIS on Win 7, the files are served at an unbelievably slow rate (150ms - 1s), thus causing the page to take up to 3 minutes to load. I have searched the internet to try to find a solution and have come up empty. Anyone have any ideas?

• jQuery width() returns 0 for a span element created on the fly?

  - by Lyon

  Hi, I'm trying to determine the width of a string. I'm using the following code but it always return 0. It seems to be that as the span element is created and not already present in the page body, jQuery width() returns 0. Is there a way such that I can get the width of the text without resorting to creating dummy html code in the page? Thanks :) $('<span>test</span>').width(); // width = 0 $('span.width').width(); // returns a width value <body><span class="width">test</span></body>

• [Web] Eventlistener for form input on iphone?

  - by ketenshi

  I'm playing around with jQTouch to create a web app on the iPhone. I'm using the scrolling extension to create the effect of a fixed toolbar on the top of the page while still able to scroll the rest of the page via a scrollable div. Everything works fine except for when a user pulls up the keyboard in order to fill in form elements in the scrollable div. The whole body is pushed to top and the ugly url bar is shown. Is there a way to prevent this?

  Hi guys, I have a very basic query string which passes a ID to a receiving page. On that page, I need to dynamically call the YouTube API, giving my playlistID. I'm having to use PHP for this, and it's a little out of my comfort zone, so hopefully someone can wade in with a quick fix for me.

• Using EXSLT dates-and-times module in XSLT 1.0 yields unknown error

  - by danielle

  I added the EXSLT dates-and-times module in my XSLT 1.0 file by declaring: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" ... xmlns:date="http://exslt.org/dates-and-times" extension-element-prefixes="date"> This doesn't affect my resulting page, but when I try to call the actual date with: <xsl:value-of select="date:date-time()"/> I receive an "Error loading stylesheet: An unknown error has occurred ()" message when loading my page. Does anyone have a suggestion as to what I might be missing? Thanks in advance!

• Frame Redirect in C#

  - by Simon Linder

  I would like to execute a frame redirect in C# from my managed module for the IIS 7. When I call context.Response.Redirect(@"http://www.myRedirect.org");the correct page is shown but also the address is shown in the browser. And that is exactly what I do not want. So I want something like: private void OnBeginRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpContext context = app.Context; // make a frame redirect if a specified page is called if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html")) { // perform the frame redirect here, but how? // so something like context.Response.Redirect(@"http://www.myRedirect.org"); // but as I said that doesn't redirect as I want it to be } } Any ideas about that?

• architecture python question

  - by tom smith

  hi. creating a distributed crawling python app. it consists of a master server, and associated client apps that will run on client servers. the purpose of the client app is to run across a targeted site, to extract specific data. the clients need to go "deep" within the site, behind multiple levels of forms, so each client is specifically geared towards a given site. each client app looks something like main: parse initial url call function level1 (data1) function level1 (data) parse the url, for data1 use the required xpath to get the dom elements call the next function call level2 (data) function level2 (data2) parse the url, for data2 use the required xpath to get the dom elements call the next function call level3 function level3 (dat3) parse the url, for data3 use the required xpath to get the dom elements call the next function call level4 function level4 (data) parse the url, for data4 use the required xpath to get the dom elements at the final function.. --all the data output, and eventually returned to the server --at this point the data has elements from each function... my question: given that the number of calls that is made to the child function by the current function varies, i'm trying to figure out the best approach. each function essentialy fetches a page of content, and then parses the page using a number of different XPath expressions, combined with different regex expressions depending on the site/page. if i run a client on a single box, as a sequential process, it'll take awhile, but the load on the box is rather small. i've thought of attempting to implement the child functions as threads from the current function, but that could be a nightmare, as well as quickly bring the "box" to its knees! i've thought of breaking the app up in a manner that would allow the master to essentially pass packets to the client boxes, in a way to allow each client/function to be run directly from the master. this process requires a bit of rewrite, but it has a number of advantages. a bunch of redundancy, and speed. it would detect if a section of the process was crashing and restart from that point. but not sure if it would be any faster... i'm writing the parsing scripts in python.. so... any thoughts/comments would be appreciated... i can get into a great deal more detail, but didn't want to bore anyone!! thanks! tom
