• Asp.Net error reporting with stacktrace

  - by Helo

  I have an Asp.Net web site set up to log errors using Log4Net (in global.asax) and redirect users to a custom error page (set up in web.config with: ). On this error page the users have the opportunity to write about what they did when the error occurred and post the description back to us to help fix the problem. My question is this: How do i connect the error stacktrace to the users error report? It appears that .Net has handled the error when it was written to the log file and the custom error page has no information about the stacktrace. If only I could see the stacktrace from the custom error page code-behind my problem would be solved.

• Detecting and reloading updated application parameters at runtime

  - by VeeKayBee

  I am working on an ASP.NET web application(using .NET 4.5 and C#).The application deals with lot of units (for measuring like KG,Litre,KM etc). So based on the selected unit we have to implement some allowed range.This values can be configured without much effort. We identified two solutions for this Keeping a configuration xml. Suppose the values in xml, does it requires an iisreset or any other thing which can take the site down for some time, if we are changing the xml file to change some validation. Keeping in Db, then use SQL dependency caching. So an update to DB can reflect the caching values.SO i believe if we change the values, it will update the cache. How much complex is this and does it effect the performance ? It will be great helpful, if we have some other method to achieve this. Thanks in advance.

• Delay garbage collection?

  - by GeoffreyF67

  I'm using chrome (the dev version for my mac). I was looking at the timeline for my page loading and I saw that there is a 150ms delay due to some garbage collection taking place while loading the page. http://cl.ly/cce10619c698a5b276e2 It's the yellow line. I was curious if there's any way to stop this, delay it, whatever so I get the page to load faster? G-Man

• How to handle printing of HTML pages?

  - by Jaran

  In my portfolio site I have listed my projects under separate tabs (tab menu). This works well except for printing which requires the user to click on a tab, print, click on the next tab and print the same page again to get everything. Being a portfolio I'd assume that visitors want to print all of the content. Is there a general way to create a different style when printing a web page? Or should I just add a printer icon on my page which redirects the user to a different page where all the data is in a big chunk and then prompt the user's browser to start printing?

• strange Django problem

  - by Pounds

  Sorrt to bother you everyone, but I really suffer a strange problem. I am working on a Django project for a company. This project worked very well before today. Today I found a page can not show images (and their corrsponding links). I checked source code of THAT PAGE, I found there are images and links, I just can not find them on the page. I checked the auth of the server and I am sure I can write things to the database. In fact, I think it is not database mistake because I can find what I want in the page source code, I just can not find them on the page. Oh my Gosh, I am going to be crazy... Has anyone suffered similar problem? What kind of problem could it be? Please help me! Thank you very much! PS: I can not provide any source code of the project because some business limit...I am really sorry...

• Wrong values reported by pyPDF for various box regions

  - by romor

  Using pyPdf, for most files I get matched results concerning various box's dimensions compared to what Acrobat reports. However for some files I get different values reported by pyPdf and Acrobat, like: pyPdf: artBox: 595.3 x 841.9 bleedBox: 595.3 x 841.9 cropBox: 595.3 x 841.9 trimBox: 517.3 x 754 Acrobat: artBox: 439.35 x 666.13 pt bleedBox: 439.35 x 666.13 pt cropBox: 439.35 x 666.13 pt trimBox: 439.35 x 666.13 pt I thought it's units issue, but then ratio between widths and heights doesn't match also, not mentioning trimBox mismatch Correct results are those reported by Acrobat of course. Does someone know why is this and is there a way I get correct dimensions by using pyPdf? Thanks couple of minutes later... After reading this question: Are PDF box coordinates relative or absolute? I figured I didn't considered uper left corner to be different then 0 (zero). It turned out that box starts at 77.95 x 87.87, so if we reduce reported values of trimBox by this values correct result is obtained. artBox: 0 x 0 bleedBox: 0 x 0 cropBox: 0 x 0 trimBox: 77.95 x 87.87 Other boxes seem with misleading values or I misinterpret them. Snippet: from pyPdf import PdfFileReader pdfread = PdfFileReader(file('my.pdf', 'rb')) page = 1 width = pdfread.getPage(page).trimBox[2]-pdfread.getPage(page).trimBox[0] height = pdfread.getPage(page).trimBox[3] - pdfread.getPage(page).trimBox[1] print width, height

• Click behaviour - Difference in IE and FF ?!

  - by OlliD

  Hey folks, i just came to the conclusion that a project i am currently working on might have a "logical" error in functionality. Currently I'am using server technology with PHP/MySQL and JQuery. Within the page there's a normal link reference with tag <a href="contentpage?page=xxx">next step</a> The pain point now seems to be the given jquery click event on the same element. The intension was to save the (current) content of the page (- form elements) via another php script using the php session command. For any reason, IE can handle the click event of Jquery right before executing the standard html command, that reloads the current page again with the new page parameter. By using FF the behaviour is different. I assume, that FF first execute the html command and afterwards execute the javascript code which handles the click event. Therefore the resultset here is wrong respectivly empty. My question now is whether you made the same experience and how you handled / wordarrounded this problem. I'd be thankful fur any of your tips or further feedback. Maybe you also have a solution on how to rethink about the current architecture. Regards, Oliver

• How to specify HTTP expiration header? (ASP.NET MVC+IIS)

  - by Marek

  I am already using output caching in my ASP.NET MVC application. Page speed tells me to specify HTTP cache expiration for css and images in the response header. I know that the Response object contains some properties that control cache expiration. I know that these properties can be used to control HTTP caching for response that I am serving from my code: Response.Expires Response.ExpiresAbsolute Response.CacheControl or alternatively Response.AddHeader("Expires", "Thu, 01 Dec 1994 16:00:00 GMT"); The question is how do I set the Expires header for resources that are served automatically, e.g. images, css and such?

• What is the best way to lazy load doubleclick ads that use document.write?

  - by user560585

  Ads requested through via doubleclick often get served from an ad provider network that returns javascript that in turn performs document.write to place ads in the page. The use of document.write requires that the document be open, implying that the page hasn't reached document.complete. This gets in the way of deferring or lazy loading ad content. Putting such code at page bottom is helpful but doesn't do enough to lower all-important "page-loaded" time. Are "friendly iframes" the best we have? Is there any other alternative such as a clever way to override document.write?

• WordPress website getting hung up for 10-15 seconds

  - by synergy989

  Problem I have a website (which loads fine): http://testupg.videve.com/ Go to the blog section (and it begins to load, gets hung up, then loads): http://testupg.videve.com/blog/ It's all one WordPress install. The only pages that are getting hung up are the blog page itself and any article page. The video pages load fine etc. What Have I done and noticed. If I disable all plugins, the blog page loads fine. I narrowed it down to DisplayBuddy plugins (Featured posts, Carousel, Slider)...as soon as I enable any single one of them, the site loads slow. The thing that doesn't make sense is, I disabled the sidebar (deleted it from the template) and the article page still loaded slow and it has ZERO instances of this plugin. I disable the plugin and the article page loads fine. How on earth can this be? I am hoping this case above can give just a little bit of insight! One other thing. The video pages use a custom taxonomy so I am wondering if its something to do with the default wordpress taxonomy. Any help is GREATLY appreciated, I have been at this thing for hours and it's time to call in some support. Cheers

• Drop Down Box (select) set URL on postback?

  - by jamone

  I have a page with a ASP.NET DropDownBox control (HTML select) that's populated with some dynamic record values. When the user selects a record the entire contents of the page is updated to reflect the selection. If a user clicks a link and leaves the page and tries to go back, it pulls up the default unselected list, and they have to reselect it again. How would be the best way to retain their selection? I currently have the page set so if the url contains PageName.aspx?recordID=5 it will select the correct dropDown option. However I'm not sure how to change the URL's query string based on the selection.

  - by Amr Mekkawy

  I'm working on a php project.. And I started building the admin login system and have already finished it and it works properly on my machine (local server) where I'm developing the project.. But when I moved it to a (web server) it didn't work properly as it was working on (local server). the problem that showed up is that when the admin get authentication to log in to the admin area, once he clicks any link in the page or even he reloads the page that page disappear and the login page appear again which mean the admin forced to log out even he didn't.

• non-cached RSLs in Flex?

  - by SteMa

  I have a project that is for several customers, the only difference is in the DB, everything else looks the same, except for the main page's text. That is loaded from an external swf file. I created a library, compiled it as an swc, imported it and using it as an RSL. The problem is that if once I've opened the page, and afterwards update the rsl (because changes in the text are needed), than it's already cached by the browser (not the flashplayer's cache but we shouldn't discuss this please!) and the updated swf won't be loaded. If I use it as an external, the page won't even start up (the browser says it's loaded, but it's blank, not even the loading progess bar of flex appear) <local:MainPage includeIn="default" currentState="{MainPageState}" id="Page" width="100%" height="100%" /> this is the code on the main page, if I comment this out, than the whole thing loads, even with the use of the "external" link-type. If it helps, in the design view, I see the component, but I get a warning for the library: Design mode could not load MainPage.swc. It may be incompatible with this SDK, or invalid. (DesignAssetLoader.CompleteTimeout)

• Change the value of an existing onclick function

  - by Mark Peach

  I have a page that is pulling in via an iframe a page of html content from a pre-existing content management system, whose content I can not directly change. I want to use jquery to alter some of the links and button locations dynamically. For links within the page I was able to change the href attr values of <a href="/content.asp">more</a> from content.asp to content2.asp using $("a[href^='/content.asp']") .each(function() { this.href = this.href.replace("content.asp", "content2.asp"); }); But the page pulled in also has form buttons that contains javascript onclick functions e.g. <INPUT type="button" value="Add to basket" onClick="document.location='/shopping-basket.asp?mode=add&id_Product=1076';"> I basically want to use jquery to select any such buttons and change the shopping-basket.asp to shopping-basket2.asp How can I select these buttons/onclick functions and change the location string?

• (C#) download embedded flash from a given URL

How else can a flash file embedded in an html page be downloaded ? ty

• Should I aim for fewer HTTP requests or more cacheable CSS files?

  - by Jonathan Hanson

  We're being told that fewer HTTP requests per page load is a Good Thing. The extreme form of that for CSS would be to have a single, unique CSS file per page, with any shared site-wide styles duplicated in each file. But there's a trade off there. If you have separate shared global CSS files, they can be cached once when the front page is loaded and then re-used on multiple pages, thereby reducing the necessary size of the page-specific CSS files. So which is better in real-world practice? Shorter CSS files through multiple discrete CSS files that are cacheable, or fewer HTTP requests through fewer-but-larger CSS files?

• Inheritance in kohana

  - by Binaryrespawn

  Hi all, I have recently started to use Kohana and I know inheritance is in infancy stages at the moment. The work around is using a $_has_one annotation on the child class model. In may case i have "page" as the parent of "article". I have something like, protected $_has_one = array('mypage'=>array('model'=>'page', 'foreign_key'=>'id')); In my controller, I have an action which queries the database. In this query I am trying to access fields form the parent of "article" which is the "page". $n->articles=ORM::factory('article')->where('expires','=',0) ->where('articledate','<',date('y-m-d')) ->where('expirydate','>',date('y-m-d')) ->where('mypage->status','=','PUBLISHED') ->order_by('articledate','desc') ->find_all(); The status column resides in the page table and my query is generating an error to the effect of "cannot find status", clearly because it belongs to the parent. Any ideas ?

• Extra GET Request on META Refresh Redirect (CGI-C)

  - by Koray Alkan

  I have a form (on page form.html) submitting with POST method to a CGI-C page - let's call it form.cgi - and what form.cgi does is it redirects the user to the previous page (to form.html) with appending query strings using HTTP-EQUIV Refresh META after 5 seconds. However, if I monitor the Web server's access.log although I see the appropriate POST request for form.cgi there is an additional GET request for form.cgi again, after 5 seconds just before redirecting the user to form.html Has anyone faced with such an issue?

• <thead> and <tfoot> in Safari

  - by AJ

  I trying to print a page with multiple tables. The problem is that any of these tables may break and carry over to the next page. Have been trying to get the table header to repeat on the second page. Am currently using thead and setting the display property to table-header-group. This works just as expected in IE and firefox but the header will not repeat in Safari. Since we are using software that converts our page to a pdf document for printing...and the 3rd party software uses a Safari engine, we are stuck with this problem. Does anyone know a way / workaround to make headers repeat if the table spans multiple pages in Safari?
