• latex page number position

  - by anton

  I am working on a long document in latex with documentclass book. I need the page number to always be in the upper right corner of each page, even if that page is the first page of a chapter (right now on 1st pages of chatpers, the page number is bottom-centered, on all other pages it's top-right). I control the position of the page number with fancyheader: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{} \chead{} \rhead{\thepage} \lfoot{} \cfoot{} \rfoot{} \renewcommand{\headrulewidth}{0pt} Also, I don;t know if the problem is realted but my chapters do not start from the top of the page. There is a white area, then comes chapter X, then a newline with the chapter line. What I also want is the chapter to start from the top of the page. The main question here is how I can get the page number to always appear in the upper right corner, I mention the thing with the chapter title position only in case that might be related. Thanks.

• How to obtain printed page count if no web-gui or driver-gui is available to show it

  - by Macgreggor at your service

  I am curious if windows print servers can keep a count of the printed pages sent to it? Can an individual PC (WinXP+)? Is there some secret command you can send it (with telnet, dos, etc)? I searched & couldn't find any questions similar to this here so lets keep this open-ended for future people who are curious. Is this more suited towards server fault? Maybe, but this is more about printers & local PC's have print servers now-a-days. Anyhow in my situation I have the following printers (yes old) I am curious on page-counts: HP Laserjet 1300 (using some kind of PC-card to LPT/Parallel adapter, then a network adapter on top of that [Netgear PS101 print server]) Canon Faxphone L80 Epson LX-300+

• Stange stream of HTTP GET requests in apache logs, from amazon ec2 instances

  - by Alexandre Boeglin

  I just had a look at my apache logs, and I see a lot of very similar requests: GET / HTTP/1.1 User-Agent: curl/7.24.0 (i386-redhat-linux-gnu) libcurl/7.24.0 \ NSS/3.13.5.0 zlib/1.2.5 libidn/1.18 libssh2/1.2.2 Host: [my_domain].org Accept: */* there's a steady stream of those, about 2 or 3 per minute; they all request the same domain and resource (there are slight variations in user agent version numbers); they come form a lot of different IPv4 and IPv6 addresses, in blocs that belong to amazon ec2 (in Singapore, Japan, Ireland and the USA). I tried to look for an explanation online, or even just similar stories, but couldn't find any. Has anyone got a clue as to what this is? It doesn't look malicious per say, but it's just annoying me, and I couldn't find any more information about it. I first suspected it could be a bot checking if my server is still up, but: I don't remember subscribing to such a service; why would it need to check my site twice every minute; why doesn't it use a clearly identifying fqdn. Or, should I send this question to amazon, via their abuse contact? Thanks!

• When should I use a UserControl instead of a Page?

  - by dthrasher

  I notice that many of the WPF MVVM frameworks seem to avoid using the NavigationWindow and Page controls in favor of composing pages using nested UserControls. The NavigationWindow and Page provide easy ways to enable back and forward navigation in the journal as well as providing an easy way to pass data among pages. Most MVVM frameworks I've seen re-implement these features in various ways. Is there a specific reason to avoid using NavigationWindow and Page?

• Access container page of a component in .net based CT

  - by Huston Lopes

  We are developing a .net based CT based on Broker query Mechanism (filter): ComponentPresentationAssembler cpAssembler = new ComponentPresentationAssembler(Page ID,Page object); In order to pass the page ID, I need to get the access of page on which the component is present. How can I access the page from package? Since this a CT, a component object would be available in page and not a page object. Tried the following piece of code, but without success: string pageURI = _package.GetValue("Page.ID"); Page objPage = (Page)_engine.GetSession().GetObject(pageURI); This is not working as there is no page object. What are the alternatives so that we can access the parent page of component from CT?

• Jquery / PHP - pre-loading next page before navigating to it.

  - by Tim

  Hey all Using jQuery, is there a way to prevent going to the next page until the animation has finished AND the next page has completely loaded (including images)? The code below works but it is a bit clunky. You can see what I am trying to achieve here: http://bit.ly/aOeYgE The first three or so pages work. But when you click to go to the homepage a few times (after it's cached) you will see that it jumps, and the animation isn't very smooth. As you can see with the code below, the height is immediately set to 0, then when the page has loaded the height is set to 500px. When users navigate to a new page, the height should go back to 0, the next page content should load, and then upon loading the new window, the first bit of code will run again to set the width back to 500px. $(".content-center").css({"height": "0px"}); $(window).load(function() { if($('.content-center').is(':not(:animated)')) { $('.content-center').animate({height: "500px"}, 450); } }); $("a").click(function(event){ $(".content-center").animate({height: "0px"}, 500); if($('.content-center').is(':not(:animated)')) { navigate($(this).attr('href')); event.preventDefault(); } }); If anyone has any suggestions or alternative ideas to this code then it would be hugely appreciated. Many thanks Tim

• Is there a way to detect when a WSS default.aspx page is updated?

  - by Alan

  That is detect when the user makes web part changes and selects to exit editing the page. I want to be able to capture a page event, then create a SharePoint task to instruct a user to translate that page to another language (note that MOSS and variations is not an option because the client wants to use the free version of SharePoint). So the customer wants essentially the same WSS site in multiple languages.

• What conditions cause a web browser to display the "Page Expired" message?

  - by RichardHowells

  I assumed that sending a page out with an expiry (a la)... Response.Cache.SetExpires(System.DateTime.Now.AddSeconds(5)); Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetValidUntilExpires(true); ...would mean that if the user hit the back button they would see the expired page. It does not seem to work that way. I found that using the back button would simply show the old (IMO expired) page. In fact in experimenting with different combinations of caching/not caching and expiry times I NEVER managed to get the "Page Expired" message out of the browser. What conditions provoke that message? Server Environment ASP .Net. I've only tested in IE8 - I'm assuming that other browsers are consistent here.

• Consolidating multiple domain names

  - by Mike

  I have a client that has three separately hosted copies of their website, each on a separate domain name. The websites are all essentially the same, bar a few discrepancies caused by badly managed updates in the past. I will soon be launching a completely new website for them, at which point, all three domain names are to resolve to the same web server. One domain name will become the default domain name that they refer to in all their literature, and the other two will simply be used as catch-alls for old links, bookmarks, and so on. I would like to know what people consider the best route to achieve this. My plan so far is: Get the new site up and running on the new webserver. Change the relevant A record of the default domain name to point to the new webserver. a) Keep the existing hosting accounts in operation. Create a list of 301 redirects from old page names on the old site to new page names on the new site. or b) Configure CNAME records for the non-default domain names, each pointing to the new webserver. Create a list of 301 redirects on the new site that redirect from old page names to new page names. If my understanding is correct, 3a will help to maintain whatever search engine rankings the sites already have (I know it's not going to be perfect), while at the same time informing search engines that the old domain names are no longer in use. What's a good approach to take here?

• Local Apache on Windows XP not finishing page requests

  - by asgeo1

  I have Apache 2.2.11 installed locally on my Windows XP (SP3) dev machine, which I setup about 3 months ago. I have just started having a strange problem in the last few week. Apache is serving some basic PHP applications like phpMyAdmin. When I make a page request, Apache appears to not finish serving all resources for that page. Firefox shows the "Transferring data from servername..." message, and the page never completes. The same problem happens in Internet Explorer too. I can sometimes tell which resource it is waiting on, because most of the page will render except for some image or similar resources. (Not sure why Firebug doesn't show this) It doesn't have the problem every page request - for page requests where most of the resources are cached in my browser, the page request will work with no problems. Or pages that are very light will work with no problems. However, if I "hard" refresh the page, I will have this problem (probably because it is requesting all page resources) Does anyone know what this could be? It is so strange that it has only just started happening - and I did not make any changes to my system (that I am aware of) I tried playing with the Apache ThreadsPerChild setting, but it did not seem to make a difference. UPDATE: I have been doing some more tests. I have been serving the most basic of pages, just a plain HTML file: <html> <body> <h1>testing</h1> </body> </html> If I request this page multiple times in a row, AND each request occurs immediately after the previous has completed, then 50% of the time the request will time out. However, if I put a 1-2 second gap between requests, then there is no problem. This correlates to what I have observed when the brower requests a real application page. When the browser has nothing cached, then all of the page resources are requested from the browser in a short amount of time - this appears to trigger the problem. UPDATE2: Nathan Long has helped me understand the issue a little better with the server-status page (see below). It is weird, it is like the server has a hickup sending data to the client. The client sits there waiting forever for data that never arrives. Closing the client process does not terminate the connection on the server - the server still has active threads for each previously attempted connection, but they just sit there - not sending any data and never terminating. (even though the client is now closed) Only a restart of the server seems to terminate them.

• Help Redirecting A Page to Another Page with adverts for 5 seconds, and then redirecting to another page.

  - by XcodeDev

  Hey, I am trying to redirect a page to another page, and that was working successfully. However I am trying to redirect the first page to another page with adverts. This page will then redirect to another page after five seconds. I am trying to do that by doing this: <?php include('ads.php'); ?> <?php sleep(2); $url = $_GET['url']; header("Location: ".$url.""); exit; ?> However it is showing the advert in ads.php perfectly, but it is not redirecting after five seconds. I am receiving this error in my web browser: Warning: Cannot modify header information - headers already sent by (output started at /home/nucleusi/public_html/adverts/ads.php:1) in /home/nucleusi/public_html/adverts/index.php on line 7 A typical link I would be redirecting to would be this: http://nucleusiphone.com/adverts/index.php/?url=http%3A%2F%2Fitunes.apple.com%2Fmx%2Falbum%2Fstill-got-the-blues%2Fid14135178%3Fi%3D14135158 Thanks in advanced.

• SQL SERVER – What is Page Life Expectancy (PLE) Counter

  - by pinaldave

  During performance tuning consultation there are plenty of counters and values, I often come across. Today we will quickly talk about Page Life Expectancy counter, which is commonly known as PLE as well. You can find the value of the PLE by running following query. SELECT [object_name], [counter_name], [cntr_value] FROM sys.dm_os_performance_counters WHERE [object_name] LIKE '%Manager%' AND [counter_name] = 'Page life expectancy' The recommended value of the PLE counter is 300 seconds. I have seen on busy system this value to be as low as even 45 seconds and on unused system as high as 1250 seconds. Page Life Expectancy is number of seconds a page will stay in the buffer pool without references. In simple words, if your page stays longer in the buffer pool (area of the memory cache) your PLE is higher, leading to higher performance as every time request comes there are chances it may find its data in the cache itself instead of going to hard drive to read the data. Now check your system and post back what is this counter value for you during various time of the day. Is this counter any way relates to performance issues for your system? Note: There are various other counters which are important to discuss during the performance tuning and this counter is not everything.

• Should each page of a Blog listing have its own Title

  - by RandomBen

  Should example.com/Blog?Page=1, example.com/Blog?Page=2, etc have the same title? I have done some research on this and SEOMoz's tools say I have duplicate titles and so does Google's Webmaster tools. If you look at top end examples like http://www.seobook.com/blog and http://www.seomoz.org/blog they both use the same title across all query of their ?Page=X URLs. So what is the better choice or does it even matter?

• How to use SharePoint modal dialog box to display Custom Page Part1

  - by ybbest

  In the part1 of this series, I will show you how to use the modal dialog box to display the custom page and close the page. You can download solution here. 1. Firstly, I create custom action on the list item ECB called Display Custom Page. To do so, you need to create an element item in SharePoint project and copy the following xml to the element file. <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <CustomAction Id="ReportConcern" RegistrationType="ContentType" RegistrationId="0x010100866B1423D33DDA4CA1A4639B54DD4642" Location="EditControlBlock" Sequence="107" Title="Display Custom Page" Description="To Display Custom Page in a modal dialog box on this item"> <UrlAction Url="javascript: function CallDETCustomDialog(dialogResult, returnValue) { SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK); } var options = { url: '{SiteUrl}' + '/_layouts/YBBEST/TitleRename.aspx?List={ListId}&amp;ID={ItemId}', title: 'Rename title', allowMaximize: false, showClose: true, width: 500, height: 300, dialogReturnValueCallback: CallDETCustomDialog }; SP.UI.ModalDialog.showModalDialog(options);" /> </CustomAction> </Elements> 2. In your code behind, you can implement a close dialog function as below. This will close your modal dialog box once the button is clicked. protected void CloseDialog() { if (HttpContext.Current.Request.QueryString["IsDlg"] == null) return; if (!ClientScript.IsStartupScriptRegistered("CloseDialogFunction")) { const string script = "<script type='text/javascript'>" + "SP.UI.ModalDialog.commonModalDialogClose(1, 1);" + "</script>"; ClientScript.RegisterStartupScript(GetType(), "CloseDialogFunction", script); } }

• dynamic urls and links on one web page

  - by John

  I am trying to figure out how to create dynamic links and urls on a static webpage. What I want to do is the following: I have a single webpage for example: MYWEBPAGEdotCOM/INDEX.HTML that will always look the same, except for one link on the page. the link would be on the page for example: LINK TO AFFILIATE: affiliatedotCOM/my-affiliate_code_here_DYNAMIC_REFERER the only thing would change is the "DYNAMIC_REFERER" with every dynamic url on this page: MYWEBPAGEdotCOM/INDEX.PHP_id=test1 MYWEBPAGEdotCOM/INDEX.PHP_id=test2 MYWEBPAGEdotCOM/INDEX.PHP_id=test3 MYWEBPAGEdotCOM/INDEX.PHP_id=test4 which would only hange the dynamic link on the page to: affiliatedotCOM/my-affiliate_code_here_test1 affiliatedotCOM/my-affiliate_code_here_test2 affiliatedotCOM/my-affiliate_code_here_test3 affiliatedotCOM/my-affiliate_code_here_test4 Can someone tell me how I could go about doing this? I just dont want to have to make 100's of pages, as this would prevent me from having to do so.

• Visual web page designer for Django?

  - by Robert Oschler

  I'm just starting my Django learning so pardon me if any part of this question is off-base. I have done a lot of web searching for information on the equivalent of a visual web page designer for Django and I don't seem to be getting very far. I have experience with Delphi (Object Pascal), C, C++, Python, PHP, Java, and Javascript and have created and maintained several web sites that included MySQL database dependent content. For the longest time I've been using one of the standard WYSIWIG designers to design the actual web pages, with any needed back end programming done via Forms or AJAX calls that call server side PHP scripts. I have grown tired of the quirks, bugs, and other annoyances associated with the program. Also, I find myself hungry for the functionality and reliability a good MVC based framework would provide me so I could really express myself with custom code easily. So I am turning to Django/Python. However, I'm still a junkie for a good WYSIWIG designer for the layout of web pages. I know there are some out there that thrive on opening up a text editor, possibly with some code editor tools to assist, and pounding out pages. But I do adore a drag and drop editor for simple page layout, especially for things like embedded images, tables, buttons, etc. I found a few open source projects on GitHub but they seem to be focused on HTML web forms, not a generic web page editor. So can I get what I want here? The supreme goal would be to find not only a web page editor that creates Django compatible web pages, but if I dare say it, have a design editor that could add Python code stubs to various page elements in the style of the Delph/VCL or VB design editors. Note, I also have the Wing IDE Professional IDE, version 2.0. As a side note, if you know of any really cool, fun, or time-saving Python libraries that are designed for easy integration into Django please tell me about them. -- roschler
