  • Render asp.net repeater as-and-when chunks of html is ready (streaming)

    - by sash
    The problem is to render huge reports. Basically we have lots of data that get rendered in html reports (mostly using repeater or gridview). As it so happens, the data started out small and now we have tons of it. There are lots of such reports already built so total rewrite is not an option. Heck, the business is not even letting us page the data. Now server memory is shooting up each time we try to render some reports. So the question is - is there some way we can bind data to repeater and have it stream html to browser as and when chunks are ready? That way we hope to not bring all that data into app server at once. I'm thinking we'll use a datareader or something to get parts of data and render it to browser. Any pointers, links, ideas?

  • Within an aray of objects can one create a new instance of an object at an index?

    - by David
    Here's the sample code: class TestAO { int[] x; public TestAO () { this.x = new int[5] ; for (int i = 0; i<x.length; i++) x[i] = i; } public static void main (String[]arg) { TestAO a = new TestAO (); System.out.println (a) ; TestAO c = new TestAO () ; c.x[3] = 35 ; TestAO[] Z = new TestAO[3] ; Z[0] = a ; Z[1] = (TestAO b = new TestAO()) ; Z[2] = c ; } } When i try to compile this i get an error message at the line Z[1] which reads as follows: TestAO.java:22: ')' expected Z[1] = (TestAO b = new TestAO()) ; ^ What i'm trying to do here is create an instance of the object TestAO that i want to be in that index within the assignment of the value at that index instead of creating the instance of the object outside of the array like i did with a. Is this legal and i'm just making some syntax error that i can't see (thus causing the error message) or can what i'm trying to do just not be done?

  • Markdown to text/plain and text/html for multipart email

    - by fphilipe
    I’m looking for a solution to send DRY multipart emails in Rails. With DRY I mean that the content for the mail is only defined once. I’ve thought about some possible solutions but haven’t found any existing implementations. The solutions I’ve thought about are: load the text from I18n and apply Markdown for the html mail and apply Markdown with a special output type for the text mail where links are put in parenthesis after the link text bold, italic and other formatting that doesn't make sense are removed ordered and unordered lists are maintained generate only the html mail and convert that to text according to the above conditions Is there any available solution out there? Which one is probably the better way to do it?

  • Moved X-cart site to Sub Directory - Need Help setting up Redirects

    - by Rich G
    I recently moved an x-cart site from a root directory to a sub directory, and also built a new Wordpress site under the root directory. The problem I am having is that I am trying to figure out a redorect combo that will show the search engines that the product pages are now under the sub directory (/store) but do not want the search engines to exclude the brand new site under the Root directory. I was thinking that if I could just have redirect any .html file (all of the product pages link to .html pages) that it would redirect to the same page just under the sub directory. The reason I cannot do everything one by one is because there are about 50k+ products that would need be changed. Any information and help would be greatly appreciated! Thank you in advanced!

  • How do I confirm a pdf loaded correctly with Watir webdriver testing

    - by Mike Rose
    This is a general type question that I dont know what code I could post that would help get an answer. So I apologize in advance, but if some piece of code would help, please let me know and Ill add it. The question is, how do I confirm that a pdf loaded in a web browser when using Ruby/Cucumber/Watir Webdriver? My test clicks on a random link that should load a pdf in a new browser window, so I cant check the url because it will vary with each test. Any ideas how I can make sure the correct pdf loads after clicking the link that should load it?

  • WPF webbrowser - get HTML downloaded?

    - by Mathias Lykkegaard Lorenzen
    I'm listening to the WPF webbrowser's LoadCompleted event. It has some navigation arguments which provide details regarding the navigation. However, e.Content is always null. Am I paying attention to the wrong event here? How can I fetch the HTML that was just downloaded as string? I tried some things which I would consider hacks, but they return a string of HTML, even though that was not the string downloaded. For instance, with that method when I go to a page which just sends me the string abc, I get the result <document><body>abc</body></document> or something similar. I would prefer not getting into any more hacks than nescessary to get this running.

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • jquery dialog is clearing my form fields and I need to return a value from a jquery dialog

    - by Seth
    1.) I have a jQuery dialog that is opened whenever a particular textbox is focused. The dialog's contents are loaded from ajax and the unique ID of the textbox that was focused is passed in the ajax call (like this): $('[name=start_airport[]],[name=finish_airport[]]').click(function(){   var id = $(this).attr('id');   if($('#use_advanced_airport_selector').attr('checked')) {     $('#advanced_airport_selector').dialog({       open : function() {         $(this).load('/flight-booker/advanced-airport-selector.php?callerID='+id);       }     });     $('#advanced_airport_selector').dialog('open');   } }); (where advanced_airport_selector is an empty div) THAT PART WORKS FINE. However, when I make my ajax call within my dialog, all my form values are reset! No matter what I do, when that dialog opens, all form values are reset (not just the value of the textbox that was focused). I simply don't understand what would cause this behavior! But that's only issue #1. 2.) I need to be able to return a value from that dialog box. I am passing the ID in the ajax query so that I can use a jquery selector to update the caller's value after certain actions are performed within the dialog box. However, I can't actually access that textbox because of DOM_ERRORS that I've never come across. It doesn't make any sense! There's way to much code to post, and it's really hard to explain, so sorry if I'm unclear as to what I'm asking.

  • Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

    - by Ori Osherov
    Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

  • Powershell Select-Object from array not working

    - by Andrew
    I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

  • How do I write in-code comments and documentation in a proper way? Is there any standard for this?

    - by hkBattousai
    I want to add documentation in my code by means of comment lines. Is there any standard format for this? For example, consider the code below: class Arithmetic { // This method adds two numbers, and returns the result. // dbNum1 is the first number to add, and dbNum2 is second. // The returning value is dbNum1+dbNum2. static double AddTwoNumbers(double dbNum1, double dbNum2); } For this example code, is there any better way of writing the comment lines?

  • Regex Remove Images with style tag from Html

    - by Mark Milford
    Hi I am new to Regex, however I decided it was the easiest route to what I needed to do. Basically I have a string (in PHP) which contains a whole load of HTML code... I want to remove any tags which have style=display:none... so for example <img src="" style="display:none" /> <img src="" style="width:11px;display: none" > etc... So far my Regex is: <img.*style=.*display.*:.*none;.* > But that seems to leave bits of html behind and also take the next element away when used in php with preg_replace.

  • Whats wrong with this method?

    - by David
    Here's the method: public static String CPUcolor () { System.out.println ("What color am I?") ; String s = getIns() ; System.out.println ("are you sure I'm "+s+"?

(Y/N) N What color am I? blue are you sure I'm blue? (Y/N) N What color am I? Yellow are you sure I'm Yellow? (Y/N) y I am Yellow I am blue I am red Why is it that the line's "I am blue" and "I am Blue" printed? Why are they printed in reverse order with red, the first entered, printed last?

  • Finding the right name for an include that is to be executed before HTML output

    - by Pekka
    I am defining naming conventions for a simple plugin framework. For example: index.php - the main plugin file info.php - returns an array with plugin information install.php - self-explanatory can you think of an elegant, short-hand name for a PHP file that contains the code that is to be executed before any HTML is output? Do any examples from other frameworks come to your mind? What I have been thinking of: head.php - misleading, could be mixed up with HTML <head> before_output.php - clumsy, too long init.php - not exactly correct start.php - current favourite

  • initWithCoder breaking my touch events (touchBegan, touchMoved, etc)

    - by Adam
    So I have a UIView that has been setup, and in each touch event handler I have an NSLog fire off a message to the console. - (void) touchesBegan:(NSSSet*)touches withEvent:(UIEvent*)event { NSLog(@"touchesBegan"); } And that pretty much works as expected. But once I implement initWithCoder (even blank) - (id)initWithCoder:(NSCoder*)coder { return self; } I no longer receive the message to my console (or can hit breakpoints obviously). This is my first app so I'm probably missing something dumb, but I've looked through various example apps and I don't appear to be missing any code that would re-enable touch events.
