• Session sometimes timesout too quick

  - by kaivalya

  I am noticing session timeouts on my asp.net mvc web app randomly without browser being incative for for more than few minutes. My understanding is the default timeout should be 20mins. But sometimes I get a timeout in couple minutes or even less than that. For example after browsing on the site for a while I might get a session timeout when i refresh a page very soon after I enter the page. This is very random but I have seen this happen quite a few times now and I am not sure how I can trace this to see why I loose sessions every once in a while whithout browser being inactive long. I checked my web.config an no timeout value is defined there so I assume it should be 20mins. Hard to debug as this does not occur regularly..

  - by Adam Wright

  Hi, I'm looking for a jquery carousel to contain image with the following requirements: must run on auto must not pause must be able to pause on image hover must have external controls that once clicked change the direction of the carousel. must be able to fadeout buttons when the carousel is moving in that direction. I've looked at jcaursel and jcaousellite but both have a pause of in auto mode or you have to specify how many items to slide. I just want it to move continously like a news ticker. Any suggestions on how to achieve this or how to customise jcaurousel or jcarouselite?

• How to assign the value of document.cookie to your browser cookies?

  - by Ricket

  I'm a developer (and therefore a tester) of a website. Our site accepts any JavaScript or HTML from an user but I haven't been successful in explaining the danger of it, as obvious as it is. So I would like to prove it by logging in as my boss to prove to him that there is definitely a real danger here. I think this will put down any of his arguments and let us move onto filtering content like this. (note this question is not about filtering, or other suggestions on JavaScript tricks) I already know how to steal the value of the document.cookie variable with AJAX and a PHP file, but once you have that string of name=value;name=value;..., how do you apply it to your own browser? This is programming related because I am asking about tools which will help me debug my web program.

• XML-RPC in CodeIgniter is for creating a API?

  - by ajsie

  I have read some tutorials about creating an API and i wonder if XML-RPC and XML-RPC server in CodeIgniter are for creating this? If yes, what are the benefits of using these classes rather than im just using regular class/methods/params to create my API interface. This is what it said in the documentation: Quite simply it is a way for two computers to communicate over the internet using XML. One computer, which we will call the client, sends an XML-RPC request to another computer, which we will call the server. Once the server receives and processes the request it will send back a response to the client.

• How to delay user login until RunOnce is completed? [Win XP]

  - by Shaitan00

  Currently I have an application that runs at startup when a user log's in to the account (administrative), as well as something under HKLM...\Run which is also executed - but I need to run something once and BEFORE both these things are executed. My solution was to use HKLM...\RunOnce which is executed before the HKLM...\Run but the task can take 30-45 seconds which gives enough time for the user Startup to be executed and launch the application prematurely. I thought of maybe including a SLEEP but RunOnce doesn't block the user account load... Then I considered the group policies but they do not have a RunOnce equivalent that I can use... Also I am not sure if Group Policy is run at the right time (never used it before). Is there anyway to make my RunOnce delay the account startup of my application, or a better place where I can execute it before both HKLM...\Run and user Startup? Or any recommended alternatives? Any ideas or help would be much appreciated... Thanks,

• Html.ActionLink in a button

  - by Pomster

  I Am trying to connect to a method in my controller, with a button. I can connect though this link: @Html.ActionLink("Print", "Print", new { id = Model.SalesContractId}) But i Don't want a link, i want my button on my dialog to do it. I have tried the following: $('#btnDialogPrint').click(function () { location.href = '<%= Url.Action("Print", "Print", new { id = Model.SalesContractId}) %>'; }); But it just redirect me to a page that say bad request. namespace Contract.Controllers { public class ContractController : Controller { CompassEntities db = new CompassEntities(); public ActionResult Print(int id) { return View(""); // This can be removed and Print code may be added } Don't worry about the code inside i will get to that once i get inside this method. Could i maybe attach a link here? <input type="button" value="Print" id="btnDialogPrint" />

• Make text appear briefly in a JPanel

  - by Roo

  Hi, I am trying to make text appear briefly before it disappears. It would be along the lines of 1) Set color to black 2) wait x amount of seconds 3) set color to background color The method I call is repaint(), which then calls paintComponent(Graphics painter). repaint() is called only if I press the space-bar. I thought of trying repaint();Thread.sleep(1000);repaint(); (I do catch the Interrupt exception, just not shown), but it only calls paintComponent once per space-bar . Is there an easy way to do this or is this something that is a bit challenging?

• Html newbie! background-image question

  - by Kevin Li

  Hi! I'm learning HTML and I wanted to practice by recreating a invoice sent to me by Electronics Expo. However, I used the background-image property and repeated it by repeat-x and now, the background stretches across the page so much that it has a horizontal bar to drag. http://htmlpocketreference.110mb.com/index.html You can see what I did in my link above. Also, I would really appreciate some advice on simplifying my CSS coding. It seems really messy and I have to move every element once something changes. -.- Thanks!

• C# Balloon Notification Popup over all other apps

  - by user1114503

  I have a balloon popup (from a notifyIcon) in C# that works perfectly, unless there is a fullscreen application on the users monitor, such as a power point presentation. In that case, the popup doesn't show at all. However, once that app exits or is minimized (or the taskbar brought to front) you can see the balloon popups again. Is there a way to make this popup show over all windows? Something like a form's "Top Most" setting? My code for the balloon is below if anyone needs it. notifyIcon1.BalloonTipText = "Issue found!"; notifyIcon1.ShowBalloonTip(5000); Thank you!

• UITableViewCell height with 0 rows

  - by Typeoneerror

  I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.

• Which is faster in memory, ints or chars? And file-mapping or chunk reading?

  - by Nick

  Okay, so I've written a (rather unoptimized) program before to encode images to JPEGs, however, now I am working with MPEG-2 transport streams and the H.264 encoded video within them. Before I dive into programming all of this, I am curious what the fastest way to deal with the actual file is. Currently I am file-mapping the .mts file into memory to work on it, although I am not sure if it would be faster to (for example) read 100 MB of the file into memory in chunks and deal with it that way. These files require a lot of bit-shifting and such to read flags, so I am wondering that when I reference some of the memory if it is faster to read 4 bytes at once as an integer or 1 byte as a character. I thought I read somewhere that x86 processors are optimized to a 4-byte granularity, but I'm not sure if this is true... Thanks!

• Processing large recordsets in Rails

  - by japancheese

  Hello, I'm trying to perform a daily operation on a larger than normal dataset (2m+ records). However, Rails seems to take a very long time performing operations on such a dataset. Operations like Dataset.all.each do |data| ... end take a very long time to complete (I assume this is because it can't fit all the items into memory at once, right?). Does anyone have any strategies on how I could handle this situation? I know SQL would probably speed up the process, but I'm looking to use the Rails environment as I can do many more complicated things to the data than I can with just SQL statements.

• SharePoint - Auto-increment dates in new records?

  - by ACal

  Hello, I have a list that's going to be updated with relatively static data weekly, and I wanted to create a workflow to do this automatically. The only field I'm having trouble with is Start Date. I want the new Start Date to be exactly one week after the previous week's (row's) Start Date, but I can't figure out how to capture this. I can't seem to find an easy way to get the value of the previous row. Now, theoretically, I could just have the workflow run once a week on a given day and use [Today] as the value for the field; however, a requirement is that the list can be populated a few weeks in advance if needed. Thanks in advance for any help you can provide!

  Hi, I am getting the error Fatal error: Cannot redeclare config() (previously declared in.../basics.php:58, in live server.

It only displays such error in live site. Please suggest solution for this. Help on this will be much appreciated.

• Problem when using \LaTeX \includegraphics with some PDF files

  - by brandstaetter

  I noticed some strange effects when including existing pdf graphics in my laTeX documents: Most file work flawlessly, but some PDFs that were created on a different machine (or from the web) cause the whole page on which they are embedded to become ever-so-slightly distorted. I only notice the difference in a side-by-side comparison, but once you see it, it's obvious. The text layout seems slightly broken, and when you zoom in you can see it better. I will try to make some screenshots to further elaborate, but in the meantime: Has anyone seen this before and how can I get rid of these distortions?

• Detect double-tap on UISlider?

  - by Randy

  I can detect single/double-taps in specific views with: NSSet *myTouches = [event touchesForView:mySpecificView.view]; but I want to detect a double-tap on the button of a slider and can't find any reference to it. Is there a replacement for "touchesForView:" where I can enter the name of my slider? usage: I have three sliders with their default value being directly in the center of the slider. Once the position of the slider has changed, I want a quick way to individually reset each slider to its default position. I currently have each slider's containing view set to respond to a double-tap, updating each slider. It works fine, but doesn't seem natural. ie.I can't double-tap on the slider itself because the slider intercepts the taps and doesn't pass them on to the surrounding view. thanks in advance

• Xcode File management. What is best practice?

  - by ian1971

  I've been using Xcode for a while now. One thing that always bugs me is the way it handles files. I like to have my files all in nested folders rather than one big physical folder, but when you create a group in Xcode by default it does not create a folder just a virtual folder within the project. I can see that virtual folders are great for linking code in arbitrary places into your project but once you get beyond a few classes I find the one big folder approach really painful. And then if you try to fix it later it takes ages and is easy to break your build. Is it possible to change this behaviour so that by default it creates a physical folder? Or am I doing it wrong and trying to cling to some other way of working? How do other people work with files in Xcode?

• AutoComplete textbox and "Hide Pointer While Typing" in windows

  - by Joe

  How can the "Hide Pointer While Typing" option be disabled by application? I'm having an issue with the cursor hiding and not getting it back without pressing escape or losing window focus. The application has been written in C# and uses WPF. A technology specific answer is not required because it'll likely be possible using any technology. Here's the scenario: A user can type in a TextBox and an AutoComplete list shows up below the box. Once the user starts typing though, he/she can no longer select an item from the drop down because there is no mouse cursor. I noticed that Firefox does not have this behavior. For example, while typing in a URL in the address bar the mouse cursor never disappears. There are other places I've seen this behavior so I know it must be possible. Any help is greatly appreciated!

• Java splitting string by custom regex match

  - by slikz

  I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?

• Occasional conversion error using SUM function

  - by user153777

  My app uses sql2000 and a select statement it uses will sometimes fail. Once a week or so the select returns the error 'Error Converting data type varchar to numeric' SQL: sum(case when ISNULL(form_prsn_id, -1) = irpd_prsn_id then convert(dec(11,2), case when valu_value = '' then '0' else isnull (valu_value,'0') end)* case when fmdt_deduction_flag = 'Y' then -1 else 1 end else 0 end) as client_sum The valu_value field is a varchar and stores some numeric and some varchar. But including my join and where clause filter it will always select numeric or empty string. When it is failing I can remove the SUM, see the data and know that its numeric. So why would the SUM function sometimes (say 5% of time) fail on data that is numeric. I wonder if SQL somehow "looks ahead" to ensure it could convert to decimal on more than just the rows returned without the sum. Note I have discovered a fix where I include ( where isNumeric(valu_value) = 1 ) Thanks

• Using Boost statechart, how can I transition to a state unconditionally?

  - by nickb

  I have a state A that I would like to transition to its next state B unconditionally, once the constructor of A has completed. Is this possible? I tried posting an event from the constructor, which does not work, even though it compiles. Thanks. Edit: Here is what I've tried so far: struct A : sc::simple_state< A, Active > { public: typedef sc::custom_reaction< EventDoneA > reactions; A() { std::cout << "Inside of A()" << std::endl; post_event( EventDoneA() ); } sc::result react( const EventDoneA & ) { return transit< B >(); } }; This yields the following runtime assertion failure: Assertion failed: get_pointer( pContext_ ) != 0, file /includ e/boost/statechart/simple_state.hpp, line 459
