• Can I modify an ASP.NET AJAX History Point?

  - by Nick

  I'm using ASP.NET 3.5 with AJAX and have enabled history on the Script Manager. I have 2 pages, Default.aspx and Default2.aspx. I'm using the AJAX History on the Default.aspx page and saving history points on the server-side. There are some dropdowns on Default.aspx that I don't want to save a history point for each change but would like to save the latest state so that when I click on a link on Default.aspx that navigates to Default2.aspx, when I click the back button on Default2.aspx to return I want the dropdowns to reflect what they were prior to clicking on the hyperlink. So what I'd like to do is modify the history point that I originally set on one of my ajax async postbacks on the client-side before the page navigates away to Default2.aspx. There is a location.hash javascript property that looks like it may do what I want but when I modify the value the Script Manager Navigate event is firing. Is there a way to prevent this event from firing? And would this then do the job?

• I created a Python egg!!! Now... what do I do with it?

  - by froadie

  I've finally figured out how to create a Python egg and gotten it to work. Now... what do I do with it? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)

• JUnit Theories: Why can't I use Lists (instead of arrays) as DataPoints?

  - by MatrixFrog

  I've started using the new(ish) JUnit Theories feature for parameterizing tests. If your Theory is set up to take, for example, an Integer argument, the Theories test runner picks up any Integers marked with @DataPoint: @DataPoint public static Integer number = 0; as well as any Integers in arrays: @DataPoints public static Integer[] numbers = {1, 2, 3}; or even methods that return arrays like: @DataPoints public static Integer[] moreNumbers() { return new Integer[] {4, 5, 6};}; but not in Lists. The following does not work: @DataPoints public static List<Integer> numberList = Arrays.asList(7, 8, 9); Am I doing something wrong, or do Lists really not work? Was it a conscious design choice not to allow the use Lists as data points, or is that just a feature that hasn't been implemented yet? Are there plans to implement it in a future version of JUnit?

• Problem with sending "SetCookie" first in php code

  - by Camran

  According to this manual: http://us2.php.net/setcookie I have to set the cookie before anything else. Here is my cookie code: if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; //20 days $ad_arr = unserialize($_COOKIE['watched_ads']); $arr_elem = count($ad_arr); if (in_array($ad_id, $ad_arr) == FALSE){ if ($arr_elem>10){ array_shift($ad_arr); } $ad_arr[]=$ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } else { $expir = time()+1728000; //20 days $ad_arr[] = $ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } As you can see I am using variables in setting the cookie. The variables comes from a mysql_query and I have to do the query first. But then, if I do, I will get an error message: Cannot modify header information - headers already sent by ... The error points to the line where I set the cookie above. What should I do?a

• How do I swap triangle icons when doing expanding/collapsing divs with Javascript/CSS

  - by SL

  I have a div that I want to toggle between displaying or not when a user clicks on a piece of text. I have a javascript function that toggles a div on or off. That works fine. What I don't know how to do is to have a triangle that points to the right or down depending on whether the div is open. My HTML looks like this: <a onclick="toggleDiv('myDiv');">Click here to expand or close div</a> <div id="myDiv" style="display:none"> ... </div> How do I add one of those triangles and have it point the right way, ideally with just HTML, Javascript, and CSS? The triangle would appear to the left of the "Click here..." string. Thanks.

• Using directory traversal attack to execute commands

  - by gAMBOOKa

  Is there a way to execute commands using directory traversal attacks? For instance, I access a server's etc/passwd file like this http://server.com/..%01/..%01/..%01//etc/passwd Is there a way to run a command instead? Like... http://server.com/..%01/..%01/..%01//ls ..... and get an output? EDIT: To be clear here, I've found the vuln in our company's server. I'm looking to raise the risk level (or bonus points for me) by proving that it may give an attacker complete access to the system

• jQuery: Load body of page into variable

  - by Nathan G.

  I'm using jQuery to load the result of a PHP script into a variable. The script is passed something that the user typed with a GET request. I want to take just what the script spit out into its <body> tag. Here's what I've tried: JS: function loader() { var typed = $('#i').val(); //get what user typed in $.get("script.php", {i: typed}, function(loaded) {dataloaded = loaded;}); alert($(dataloaded).find('body')) } But it just displays [Objec object]. How can I get a useful value that is just the contents of the body of a loaded page? I know the PHP works, I just need the JS. The script echos something like 1!!2 (two numbers separated by two exclamation points). Thanks!

• Java: Is it possible to take a GUI Panel and output it into a picture?

  - by user369748

  So I have this chart that's a little special. Kind of like an XY plot of points but my boss wanted to look like a bunch of boxes rather than dots connected by lines. And I basically made a chart using gridlayout and a whole bunch of cells that I'll be colouring in black or white depending on the data. Now he sorta wants it to be outputted to a image file. Is there any way to save a Panel into a picture? He wants to display not only the data but also save a visual representation of the data into an image file.

• Location inheritInChildApplications kill debugger?

  - by chobo2

  Hi I am wondering is this normal when you add this into your web.config <location path="." inheritInChildApplications="false"> </location> The debugger should stop working. Like when I add this to my site and try to run in debug mode it won't activate any of my debug points nor will it lock up Visual studios 2008. I can have it running and still make edits to my C# code. I take the line away and I get the debug mode back and it locks up VS2008.

• Understanding a lighttpd.conf file?

  - by AP257

  Hi all, I've been given a lighttpd.conf that someone else wrote and need help working out how to serve it. I'm 90% of the way there but stuck... The index.html page appears, but links and CSS files don't point to the right place. To clarify, the links and CSS files are all pointing to a 'file:///' URL. So styles.css in the HTML header points to file:///html/styles.css, whereas it should be going to http://url.com/styles.css Maybe url.rewrite or url.redirect isn't working properly? server.document-root = "~/html" server.port = 28001 mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) url.rewrite = ( "^(.*)/($|\?.*)" => "$1/index.html", "^(.*)/([^.?]+)($|\?.*)$" => "$1/$2.html" ) $HTTP["scheme"] == "http" { url.redirect = ( "^/platform/index.html$" => "/platform", "^/about/company.html$" => "/about/company",, ) }

• Change IP where domain is pointing

  - by Christian Sciberras

  This is probably a very strange request. I need to programmaticaly (via code) change the IP where a domain name is pointing to. IE: xyz.com points to 100.100.100.100 setIP('xyz.com','100.100.100.100'); I know this [code] is practically impossible, however, what I need is to do this via domain host API etc or other possible ways you might think of. I'd be happy even if it weren't anything more then sending an email to the DNS owner/host. Do you know of anything the like or which might help? (nb: considered throwing this at ServerFault, but felt it more at home here ;) ) Cheers!

• Nesting arrays into NSDictionary object (Objective-C)

  - by antalbud

  I would like to define tasks using NSDictionary, which I'd like to save in a plist file (I didn't have much luck with Core Data so far), but got stuck at two points: -- When using initWithObjectsAndKeys: I can change the data type to number or boolean, using NSDate's numberWithInt: and numberWithBool: methods, respectively. I can't seem to find the method to change the type to date though. I couldn't find anything like that in the documentation. -- The second problem I ran into was with the nested arrays. How can I add them to the dictionary? I have uploaded a picture to here of what I am trying to achieve. Thank you in advance!

• Output of Iterable.sliding as Tuple

  - by ziggystar

  The method sliding on collections returns a sliding window of given size in the form of X[Iterable[A]] with X being the type of the collection and A the element type. Often I need two or three elements and I prefer to have them named. One ugly workaround for sliding(2) is the following: points.sliding(2).foreach{ twoPoints => val (p1,p2) = (twoPoints.head,twoPoints.last) //do something } This sucks and only works for two elements. Also note that (a,b) = (twoPoints(0),twoPoints(1)) doesn't work. Help me!

• hook to save action in eclipse plugin

  - by 4485670

  I want to create a Google Closure Compiler plugin for eclipse. I already have a popup menu entry to compile a Javascript file to its minified version. But it would be more than helpful if every time you save a *.js that minified version would be generated automatically. I read/heard about natures and builders, extension points and IResourceChangeListener. But I did not manage to figure out what I should use and especially how to get it to work. Is there a working example of a plugin that does "the same kind of thing" so I can work from that or a tutorial to write such? With the answer below I searched for projects that use the IResourceChangeListener and came up with this code: manifest: http://codepaste.net/3yahwe plugin.xml: http://codepaste.net/qek3rw activator: http://codepaste.net/s7xowm DummyStartup: http://codepaste.net/rkub82 MinifiedJavascriptUpdater: http://codepaste.net/koweuh There in the MinifiedJavascriptUpdater.java which holds the code for the IResourceChangeListener the "resourceChanged" function is never reached.

• How can I select the first child of all the children of a jQuery object?

  - by sawa

  I have a <tr> which includes several <td>s, each of which includes exactly one <div>, which may have further structure: <tr id="foo"> <td><div>...</div></td> <td><div>...</div></td> ... <td><div>...</div></td> </tr> Given a jQuery selector obj = $('#foo'), how can I get a selector that points to all the <div>s directly under a <td> under the <tr> (but nothing within the <div>s)? Probably chldren() and/or find() may be relevant, but I am not sure.

• MySQL Database || Tables Issue

  - by user1780103

  I'm trying to write up a script where the user is able to purchase an amount of points for dollars. I want the transaction to be inserted into MySQL. I keep facing a: "Column count doesn't match value count at row 1" error. And I have no idea what I'm doing wrong. I have written up this: mysql_query("INSERT INTO paypal_donations VALUES (NULL, ".$account_id.", ".$char_id.", ".$price.", ".$dp.", NOW(), NOW(), 'Started', 0, 0, '', '');") or die(mysql_error()); But I don't know what to execute in MySQL, since I've never worked with it before. Could anyone write up a quick script that I can insert into MySQL for it to work.

• how do I repaint an applet while moving a sprite?

  - by Nagrom_17

  I have a little java applet where I create 2 threads, one thread repaints and the other moves an image from a point to where the user clicks. The problem is that when I call the move function it loops until the image is where the user clicks but it wont repaint until I break out of the loop even though the thread doing the moving and the thread doing the painting are separate. shortened version of key points: my program is an applet using the paint() method I have 2 threads one moves an image and the other paints that image when I am moving the image it is in a while loop the painting thread is still calling repaint() but that is as far as the call goes, it never repaints thank you for your time.

• Subtracting months/years from boost::posix_time::ptime

  - by Zack

  I have a boost::posix_time::ptime that points to March 31st 2010 like this: ptime p(date(2010, Mar, 31)); I would like to subtract a month (and possibly years) from this date. From the docs I see these two operators: ptime operator-(time_duration) and ptime operator-(days) but none of them can work with months/years. If I try and do: time_duration duration = hours(24 * 30); ptime pp = p - duration; I'm getting March 1st and if I'm trying: ptime pp = p - days(30); I'm still getting March 1st, while I'd like to get February 28th. How can I achieve my desired result? (I would like to get the desired result also when subtracting a month from March 28, 29, 30)

• See queries that hit SQL

  - by Shaded

  I have a really basic stupid easy question about sql... and I'll probably get -100 points... but here it goes anyway... Is there a way using sql 2008 Management Studio to look at the queries that hit the server? I'm trying to debug a program and I get messages like "Incorrect syntax near the keyword 'AND'". Since the queries are being dynamically generated it's a hassle to figure out what is going to the server. Any help is appreciated!

• Entity diagram with tables that have foreign keys that point to a non-PK column do not show relation

  - by Jason Coyne

  I have two tables parent and child. If I make a foreign key on child that points to the primary key of parent, and then make an entity diagram, the relationship is shown correctly. If I make the foreign key point to a different column, the relationship is not shown. I have tried adding indexes to the column, but it does not have an effect. The database is sqlite, but I am not sure if that has an effect since its all hidden behind ADO.net. How do I get the relationship to work correctly?

• AS3/AIR: Managing Run-Time Image Data

  - by grey

  I'm developing a game with AS3 and AIR. I will have a large-ish quantity of images that I need to load for display elements. It would be nice not to embed all of the images that the game needs, thereby avoiding having them all in memory at once. That's okay in smaller projects, but doesn't make sense here. I'm curious about strategies for loading images during run time. Since all of the files are quite small and local ( in my current project ) loading them on request might be the best solution, but I'd like to hear what ideas people have for managing this. For bonus points, I'm also curious about solutions for loading images on-demand server-side as well.

• Access Ruby on Rails 'public' directory without relative path

  - by huntca

  I have a flash object I wish to load and I belive the best place to store that asset is in the public directory. Suppose it's stored in public/flash, there must be a better way to path to the swf than what I've done below. Note the 'data' element, it has a relative path. def create_vnc_object haml_tag :object, :id => 'flash', :width => '100%', :height => '100%', :type => 'application/x-shockwave-flash', :data => '../../flash/flash.swf' do haml_tag :param, :name => 'movie', :value => '../../flash/flash.swf' end end Is there some rails variable that points to public?

• What key concepts and nuances in C++ you know?

  - by Narek

  What kind of key points and concepts should a person know from C++ (and from programming in general) to be considered that he/she possesses C++ (and programming, in general) skills good. e.g. //Even if sizeof(T) may not be equal to 1, this code steps over array elements T v[]; for(T *p = v ; *p != 0 ; p++) cout<<*p<<endl; P.S. I hope by exchanging this info we will help each other to know C++ and programing thechnics better by doing explicit our notion that we got from practice.

• Replacing characters in Ruby string according to some rule

  - by Kyle Kaitan

  In Ruby, I have a string of identical characters -- let's say they're all exclamation points, as in !!!!. I would like to replace the characters at certain indices with '*' if the integer corresponding to that index meets some criteria. For example, let's say I want to replace all the characters whose indices are even numbers and are greater than 3. In the string !!!!!!!! (8 characters long), that results in !!!!*!*! (indices 4 and 6 have been replaced). What's the most compact way to do this?

• Matplotlib Contour Clabel Location

  - by jotimaz

  I would like to control the location of matplotlib clabels on a contour plot, but without utilizing the manual=True flag in clabel. For example, I would like to specify an x-coordinate, and have labels created at the points that pass through this line. I see that you can get the location of the individual labels using get_position(), but I am stuck at that. Any help would be greatly appreciated. Thanks! EDIT: The above image is an example plot that I would like to apply this method to. The default label positions are inconvenient -- the flat areas between Day 2 and Day 4 would be more visually appealing.
