• How to use Preprocessor directives in MVC aspx pages

  - by Zuber

  I am using MinifyJS.tt which is a T4 template to minify all my JS files automatically. In my aspx files, I am referencing all the javascript files. Now, I want to add a condition (maybe compiler directive) to use the original JS file when I am debugging the application, and to use the minified JS files when I simply run the application without debug. I tried using #if in the aspx page, but that did not seem to work. Can we make use of preprocessor directives in aspx pages? Is there an alternative way to achieve my goal?

• .NET - downloading multiple pages from a website with a single DNS query

  - by lampak

  I'm using HttpRequest to download several pages from a website (in a loop). Simplifying it looks like this: HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create( "http://sub.domain.com/something/" + someString ); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //do something I'm not quite sure actually but every request seems to resolve the address again (I don't know how to test if I'm right). I would like to boost it a little and resolve the address once and then reuse it for all requests. I can't work out how to force HttpRequest into using it, though. I have tried using Dns.GetHostAddresses, converting the result to a string and passing it as the address to HttpWebRequest.Create. Unfortunately, server returns error 404 then. I managed to google that's probably because the "Host" header of the http query doesn't match what the server expects. Is there a simple way to solve this?

• .NET MVC - Storing database result during single page result?

  - by ropstah

  Fairly simple issue which is solved in PHP by using a static variable. private static $pages; public function Pages() { if($pages == null) { $pages = new PageCollection(); $pages->findAll(); } } Everywhere in my code I use Pages()::someFindFunction() to make sure the results are fetched only once, and I use that same collection. I want the same in my .NET MVC application: use something like: <%=MySite.Pages.findById(1).Title%> In the code below, if I use a private variable, or if I use a public class with shared variables (doesn't matter) they are both persisted during the entire application. I want them to load the same way PHP does, once per request. Now where do I store the .NET equivalent of private static $pages, so that the code below works? //what to do with $pages?? Public Module MySite Public Function Pages() As PageCollection If $pages Is Nothing Then $pages.loadAll() End If Return $pages End Function End Module

• cakephp filter index pages according to foreign keys

  - by Marki

  Hi there, I'm pretty new to CakePHP and was missing a crucial feature not generated as scaffold: filtering. What do I have to do to provide dropdowns or multi-selects on the index pages for each field that is a (foreign) key, thereby allowing to filter the table ("OR" inside multi-select, "AND" between different multi-selects, if any)? From what my websearch has shown me there are many more people trying to accomplish the same thing, although I couldn't find anything that would work for me because either they have text fields and do wildcard filtering, or the plugins they propose only work for 1.2 whereas i now started with 1.3 etc. etc. Can someone alleviate the confusion and maybe present some working code or direct me to the definitive guide[tm] where this matter has been solved? Thx

• How to stretch a table over multiple pages.

  - by lexu

  I have a Table (multiple rows, multiple columns, see below ) that is longer than one page. How can I tell LaTeX to continue on the next page. Adding a \newpage didn't work Manualy 'ending' and 'reopening' the table works, but is very tedious, since the table will be many pages long. \begin{tabular}{lp{13cm}} AAAAAAAAAA & FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR\ BBBBBBBBBB & FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR\ CCCCCCCCCC & FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR\ ...

• Limit JavaScript and CSS files on ASP.NET MVC 2 Master Page based on Model and View content

  - by Zack Peterson

  I want to include certain .js and .css files only on pages that need them. For example, my EditorTemplate DateTime.ascx needs files anytimec.js and anytimec.css. That template is applied whenever I use either the EditorFor or EditorForModel helper methods in a view for a model with a DateTime type value. I've put this condition into the <head> section of my master page. It checks for a DateTime type property in the ModelMetadata. <% if (this.ViewData.ModelMetadata.Properties.Any(p => p.ModelType == typeof(DateTime))) { %> <link href="../../Content/anytimec.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/anytimec.js" type="text/javascript"></script> <% } %> This has two problems: Fails if I have nested child models of type DateTime Unnecessarily triggered by views without EditorFor or EditorForModel methods (example: DisplayForModel) How can I improve this technique?

• asp.net webservice user management across pages

  - by nakori

  I'm developing a site that will display confidential readonly information, with data fetched from a WCF service. My question: What is the best approach to user management across different information pages. The service returns a collection with customer info after a secure login. My idea is to have a Customer object class that is stored in session. Is it possible to use things like HttpContext.Current.User.Identity.IsAuthenticated followed by HttpContext.Current.Session["UserId"] without using a database with role-based security? Would I be better off with a combination of local database, Linq to SQL or datasets rather than using just class objects for data fetched from service? thanks, nakori

• Refresh a control on the master page after postback

  - by Andreas

  Hi all! What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this: <div> <asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc"> </asp:BulletedList> </div> When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this: blstValidationErrorMessage.DataSource = validationMessageCollection; blstValidationErrorMessage.DataBind(); The save button is located inside an updatepanel: asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional" Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed. So my question is, how do i make the bulletlist refresh after the postback? Thanks in advance.

• Favicon for all the pages in my website

  - by Senthil Kumar

  I've learned that the way to add favicon for a web page is to have the following lines in the page. <link rel="SHORTCUT ICON" type="image/x-icon" href="http://mysite.com/faviconfilename.ico"/> <link rel="icon" type="image/x-icon" href="http://mysite.com/faviconfilename.ico" /> Should i add this code in each and every page my site has?? I use Apache - tomcat clustering to serve pages. Is there any other easy way to do this?

• Reportviewer - Print report - matrix report expanding horizontally to multiple pages, avoid repeating row header

  - by abc0077

  I am generating a matrix report dynamically using report viewer version 9.0 in visual studio 2010. If i export save and print then it works normally. If there more columns report expands horizontally across mutiple pages. If i give Print option available in the toolbar of the report viewer. The columns are moved to second page which is correct but the row headers (product 1, product 2) should not be repeated in the second page.In the second page report should have all details except the product information. I am also interested to know whether it is the functionality of this version report viewer.

• passing values to pages

  - by Indranil Mutsuddy

  Hello friends, What i am trying here is to pass values to other pages. When i include the following code private void Button1_Click(object sender, System.EventArgs e) { // Value sent using HttpResponse Response.Redirect("WebForm5.aspx?Name="+txtName.Text); } if (Request.QueryString["Name"]!= null) Response.write( Request.QueryString["Name"]); everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong?? Now I tried the same thing using session i.e. Session["MemberId"] = this.TxtEnterMemberId.Text; if (MemberSex.Equals("M")) Response.Redirect("PatientDetailsMale.aspx",false ); Page_load event of the other page if (Session["MemberId"] != null) mid = Session["MemberId"].ToString(); IT Works..Could u guys explain the behaviour please? P.S. Can anyone give a breif in layman words about SessionId and its usage. Thanking you, Indranil

• Detect IE setting: check for newer versions of stored pages "never"

  - by xx

  I understand there isn't a way to interrogate a users IE settings directly due to security reasons, but is there a way to derive this answer with some other mechanism? I would like to stop a user from using my site if the setting "Check for newer versions of stored pages" is set to "Never". Any suggestions? Is there a way I could test for this using javascript? An example of what I am trying to accomplish is this: While it is not possible to check IE settings to see if you are running a popup blocker, that is a way to "test" for a popup blocker via javascript. I am looking for something similiar but for the cache setting, not the popup blocker.

• Fetch pages translated by Google? (PHP)

  - by mathon12

  Hi, I have a bunch of big txt files (game walkthroughs) that I need translating from English to French. My first instinct was to host them on a server and use a PHP script to automate the translation process by doing a file_get_contents() and some URL manipulation to get the translated text. Something like: http://translate.google.com/translate?hl=fr&sl=en&u=http://mysite.com/faq.txt I found it poses two problems: 1) there are frames 2) the frame src values are relative (ie src="/translate_c?....") so nothing loads. Is there any way to fetch pages translated via Google in PHP (without using their AJAX API as it's really not suitable here)?

• how to store dynamically generated pages in html?

  - by Dharmik Bhandari

  I'm working on ASP.net MVC3 Web application that is facing scalability issue. For improving performance I want to store dynamically generated pages in html and serve them from generated html directly rather then querying database for each page request. I'm sure this will dramatically increase performance. Can any one share any hint / example / tutorial on how to do it? And what are challenges? I would also like to know how others are handling performance issue for large e-commerce sites with at-least thousand categories and 200k products with at least 200-500 concurrent visitors? What are the best approaches? Thanks in advance.

• Localizing other pages in Settings.bundle

  - by joneswah

  I have other pages within my app preferences which are stored as separate files within the settings.bundle. It has come time to localize my app and I can only seem to get the Root values to localize. I was wondering whether there was a trick? The following image shows that my second screen is stored within a file called "MyPrefs.plist" and I have created a corresponding named file "MyPrefs.strings" in the en.lproj directory. Mirroring the same naming and location as the Root.plist and Root.strings. The values with the Root.plist are converted as expected but not in the extra screen. Is there any trick to localizing secondary screens with the settings.bundle?

• Using GET instead of POST to delete data behind authenticated pages

  - by Matt Spradley

  I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?

• Problem opening Solr *.jsp pages with urllib2.urlopen.

  - by nestling

  I'm trying to open a page at http://localhost:8983/solr/admin/stats.jsp but urllib2.urlopen returns a blank string. It works fine for solr/ and solr/admin, but for all the pages above /solr/admin/ I get nothing but a blank string. 76]: t = urllib2.urlopen('http://localhost:8983/solr/admin/stats.jsp') 77]: s = t.read() 78]: s 78]: 79]: type(s) 79]: <type 'str'> 80]: urllib2.urlopen('http://localhost:8983/solr/admin/registry.jsp').read() 80]: In [84]: urllib2.urlopen('http://localhost:8983/solr/admin/schema.jsp').read() Out[84]: I know this isn't a problem with urllib2, but beyond that I am at a loss. I wish solr (or jetty) had an easy to get to log file, so that perhaps it could tell me its side of the story.

• Cuda program results are always zero in HW, correct in EMU??

  - by Orion Nebula

  Hi all! I am having a weird problem .. I have written a CUDA code which executes correctly in emulation and all results show up.. however, when executed on hardware "G210" .. the results in the result memory are always 0 I am passing two vectors to the kernel, one with random variables the other is initialized to zero, the code copies the first vector to shared memory, does some swapping and other operations and then writes back the results on the second vector (the one with the initial 0's) I am using double precision, the -arch sm13 flag is used, all memory allocation also use sizeof(double) .. I have checked if the kernel is invoked, it does .. so no problems here .. the cudaMemCpy has no problems .. what could be the problem .. :( why would it work in emulation but not on HW I am quite confused .. any ideas?

• Examples of when to use PageAsyncTask (Asynchronous asp.net pages)

  - by Tony_Henrich

  From my understanding from reading about ASP.NET asynchronous pages, the method which executes when the asynchronous task begins ALWAYS EXECUTES between the prerender and the pre-render Complete events. So because the page's controls' events run between the page's load and prerender events, is it true that whatever the begin task handler (handler for BeginAsync below) produces, it can't be used in the controls' events? So for example, if the handler gets data from a database, the data can't be used in any of the controls' postback events? Would you bind data to a data control after prerender? PageAsyncTask pat = new PageAsyncTask(BeginAsync, EndAsync, null, null, true); this.RegisterAsyncTask(pat);

• How to see what objects lie in which generation in YourKit?

  - by prams

  I am using YourKit (11.0) to try to profile my j2ee app. The app uses java 6 and running on 64-bit linux (centos). I was told that YourKit possibly tells us which objects exist in which generation (eden, old, etc) at any given point of time. On a side note, I am trying to chase a problem where memory usage keeps increasing until a major collection happens (every 4 hrs) and I am suspicious about few particular objects, so I am interested to know where those objects lie at different times. Fortunately I know lot of memory is being consumed in one particular area of code (so other objects are possibly directly being put into the old gen), but don't exactly know how much of that memory is being put into eden space, how much is being collected by the minor collections, etc. Thanks.

• Java Web App: Passing form parameters across multiple pages

  - by digiarnie

  Hi, what is the best practice or best way of passing form parameters from page to page in a flow? If I have a flow where a user enters data in a form and hits next and repeats this process until they get to an approval page, what ways could I approach this problem to make the retention of data as simple as possible over the flow? I guess you could put all the information as you go in the session but could you get into memory issues if a lot of people are using your app and going through the flow at the same time?

• SSRS mysterious extra pages

  I have two reports that are setup with the same page dimensions- A4 portrait, with page margins of 1cm. When I run the reports seperately and print them they both come out as expected: fitting into the width constraint of the page. However, when I include one report as a subreport in the other and then run and print the "master" report I start to experience problems. Even though both reports appear I get extra blank pages appearing every other page in the output. I'm sure I'm missing a simple trick - probably with the page sizes of the two reports but I can't figure it out - any pointers? I don't mind changing the setup of the subreport as it will never be run as a seperate eport in the wild, I only included that step to prove that it did indeed fit within the page!
