• ASP control event handler not firing on postback?

  - by Polaris878

  Hello, I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago. We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too... Thanks

• jQuery.keypad Performance Issues

  - by John Duff

  I am working on a Kiosk Touch Screen application and using the JQuery.keypad plugin and noticing some major performance issues. If you click a number of buttons in rapid succession the CPU gets pegged, the button clicks don't keep up with the clicking and some button presses even get lost. On my dev machine this isn't as noticeable, but on the Kiosk itself with 1 gig of ram it's painful. Trying the demo keypad at http://keith-wood.name/keypad.html#inline the one with multiple targets (which is the case with mine) has the exact same issues. Does anyone have any suggestions on how we might be able to improve this? The Kiosk runs in Firefox only so something specific to that would work. I'm using v1.2.1 of jquery.keypad and just upgraded to v1.4.2 of jquery.

• System.Web.HttpException in asp.net mvc 2 on images and javascript files

  - by Rippo

  Hi I am getting the following errors reported by ELMAH on my asp.net mvc 2 site for javascript files, images etc. System.Web.HttpException: The remote host closed the connection I have done some research and it appears that the user/bot is clicking a link on the site before the page has fully loaded. Now this error never occurs on a controller action but always on a file that is on disk. e.g. /Content/CmsImages/logo.png /Content/CmsImages/MemberImages/Photo-001605.jpg /Content/jquery.tickertype.js So this means that all static files are being routed through the mvc pipeline. What options do I have?

• WCF: generic list serialized to array

  - by OpticalDelusion

  So I am working with WCF and my services return types that contain generic lists. WCF is currently converting these to arrays over the wire. Is there a way I configure WCF to convert them back to lists afterwards? I know there is a way by clicking advanced when you add a service reference but I am looking for a solution in configuration files or something similar. [DataContract(IsReference = true)] public class SampleObject { [DataMember] public long ID { get; private set; } [DataMember] public ICollection<AnotherObject> Objects { get; set; } } It is very odd, also, because one service returns it as a list and the other as an array and I am pretty sure they are configured identically.

• Single click to activate last tab in windows 7 internet explorer (like FF)

  - by Kirk Hings

  Windows 7 annoyance: the jump lists are fine for hovering over the taskbar items, great go ahead and show me previews of all the open instances and maybe I'll pick the exact one I want. However this works different between IE and FF. Hovering over the FF icon just shows me the single FF window, not any of the tabs I have open. Clicking it means my FF window opens and I'm at the last tab I was on. Great, normal behavior, one click and I'm in. Hovering over the IE icon shows me all the tabs in my single IE window. Ok, but I just want to go back to my last active IE tab. I can't! I am forced to click twice to go back to any IE tab. Sure it's a minor annoyance, but as I'm developing throughout the day I find it more and more annoying. Any ideas to fix so I can just click the IE taskbar icon once and it pulls up the last tab I was on?

• @@TRANCOUNT and a current connection

  - by AspOnMyNet

  Assume I connect to SQL server 2008 via SQL Server Management Studio ( SSMS ) and open new window W1 by clicking on New Query tab and write the following inside W1: BEGIN TRANSACTION; If I execute this statement 5 times, and then write (inside W1) SELECT @@TRANCOUNT; , then the value returned will be 5. But if I open another window W2 ( inside the same SSMS instance and thus on the same connection ) and write inside W2 SELECT @@TRANCOUNT; then value returned will be 0. @@TRANCOUNT variable returns the number of active transactions for the current connection. Both W1 and W2 windows were opened on the same connection, so shouldn’t ( according to the above quote ) in both W1 and W2 variable @@TRANCOUNT hold the same value? thanx

• Extracting an interface from .NEt System classes

  - by Thomas

  When using Visual Studio it is easy to extract an interface from a class that I have written myself. I right click on the class and select 'Refactor' then select 'Extract Interface'. Let's assume for a second that I wanted to create a ConfigurationManager wrapper and write some tests around it. A quick way to do that would be to extract an interface from ConfigurationManager by right clicking it, then 'Go To Definition' and then from inside the class select 'Refactor' then select 'Extract Interface'. Then I would simply create my wrapper class, inherit from my newly created interface, and then implement it and I have a great starting point for my wrapper class. However, extracting an interface from any .NET system classes is not possible, probably because it's just meta data about the classes and not the classes themselves (or I am doing it wrong). Is there an easy way to do what I am trying to accomplish? I want to ensure I am not wasting time typing what I don't need to be typing. Thanks

• How do I make OneNote 2007 images searchable when inserted via code?

  - by Scott Bruns

  When I insert an image into OneNote 2007 using C# my images have 'Make Text in Image Searchable' set to Disabled. How do I insert an image with Make Text in Image Searchable enabled, or how do I enable this property after the image is imported. I have already imported a lot of images. How to I make the existing imported images searchable? I already know how to do this manually by right clicking the image and setting the language. The OCR works fine, I just need to do it automatically.

• WinForms / .Net interactive world map - how?

  - by FerretallicA

  In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?

• How to display the dynamically created elements for some time?

  - by Holicreature

  i have some rows of data displayed in a table and on mouse over of each row i've list two buttons inside a div element and then display it for some time. And i've associated some functions to be called on clicking the buttons that are dynamically created and displayed elements.. So what i did was i wrote a function which will create elements dynamically and place them exactly where i wanted using styles. And i wrote another function which will remove these dynamically added elements. I called them on mouseover and mouseout events of the row. now when i move mouse out the row to click the button they get disappeared bcoz of my mouseout function. So how can i proceed this? And what is the perfect method to create these kind of stuffs?

• Ajax and sophisticated graphics in Java web-app

  - by EugeneP

  In my opinion WWW will sooner or later come to full-blown AJAX web-sites, so that we wouldn't have page reloads every time you click somewhere. Now I want you to ask this. What tools and frameworks can one use to make a Java Web-application running on Tomcat have AJAX functionality like "in-place, with no page reloading" table sorting by clicking on its column header, multi-tabs that enable opening at once the new screen to the user without reloading a page, saving data in the database without reloading a page, and other similar things that we do not usually see on web pages. That's all should probably be based on AJAX. But how to integrate this AJAX functionality with existing java web-frameworks, let's say Spring MVC? Or maybe there are other frameworks that better suit such needs but that can be integrated with core Spring?

• Handle leaks with .NET System.Threading.Thread class

  - by Mahno

  I've a problem that number of Handles in my app is continuously growing. I did the debugging and recognize that this is caused by System.Threading.Thread class which is used for some routine. To simplify the debugging I’ve created a sample .NET application: ... private void button1_Click(object sender, EventArgs e) { Thread t = new Thread(DoWork); t.Start(); } public void DoWork(object parameter) { // Do something... } ... Each time I’m clicking the button, a thread is created using System.Threading.Thread class. The problem is that looks like the thread do not frees Handles because each click cause number of Handles growing by ~5. The question is: how can I manually free all Handles created by System.Threading.Thread class? Thanks in advance.

• Advice about testing an application before release?

  - by Troy

  I would like to get some tips from peer developers about how you go about testing an application you developed, prior to release to QA. Keep in mind, this is a small scale application (requirements are verbal), and so doing formal testing processes wont work, especially, since your boss told you to develop this app quick, push it out the door. Despite the time restraints, I would like to make sure it is bug free, however, numerous times in the past, I have had the app sent back to me because clicking the "Reset" button, messes up the other controls alignment etc. I know there are people out there that develop small scale apps fast, and send them out with minimal bugs. How can I achieve that? I researched this post, but it didnt quite answer my question. Testing your code before releasing to QA

• jquery hide all open divs and toggle

  - by Kyle

  I have 2 links and depending on which one they click on want to close all others and show only the information for that link. Example: <div class="shipping-container"> <a href="#" class="ups">Show UPS info</a> <a href="#" class="fedex">Show Fedex info</a> <div class="ups info" style="display:none">the info for ups</div> <div class="fedex info" style="display:none">the info for fedex</div> </div> Any ideas how I can do this with Jquery toggle for clicking one of the links and hide all others if there open. I only want to show info for one shipping method at a time. Also I would like an option for the user to click showall and all of them are displayed, if possible. Thanks in advance....

• How can I keep gnu screen from becoming unresponsive after losing my SSH connection?

  - by Mikey

  I use a VPN tunnel to connect to my work network and then SSH to connect to my work PC running cygwin. Once logged in I can attach to a screen session and everything works great. Now, after a while, I walk away from my computer and sooner or later, the VPN tunnel times out. The SSH connection on each end eventually times out and then I eventually come back to my computer to do some work. Theoretically, this should be a simple matter of just restarting the VPN, reconnecting via SSH, and then running "screen -r -d". However apparently when the sshd daemon times out on the cygwin PC, it leaves the screen session in some kind of hung state. I can reproduce a similar hung state by clicking the close box on a cygwin bash shell window while it's running a screen session. Is there any way to get the screen session to recover once this has happened, so that I don't lose anything?

• 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?

• Is it possible to prevent a locally-running SWF (AS3) from downloading from my website?

  - by Matt

  I've got a crossdomain.xml file which allows SWFs running on only a certain few domains to download resources from my domain. However, one simple way around this is for a user to download the SWF to their local machine, and run it there (i.e. by double-clicking on it within Windows Explorer, not by running through http://localhost). It seems that when this happens, the crossdomain.xml file is ignored. I understand that in my actionscript, I can do this: if (Security.sandboxType.indexOf(Security.REMOTE) == -1) // running locally - don't allow However it is incredibly easy for someone to decompile the SWF and simply remove this line. Is it possible to do something on the server side to stop a locally running SWF to download from my site? I tried checking the referrer but this field often isn't populated. Does anyone have any other ideas? Thanks, Matt

• Link to specific page on Google Document Viewer on iPad

  - by Debarupa De

  I am thinking of using the Google Document Viewer to show PDF files that are hosted by our company server. The scenario is: A webpage will contain a menu with menu items that are actually different pages of a PDF file. After clicking a menu item, that particular page from the pdf will be displayed on that same web page This project is targeted for mobile devices (iPad, for now) Now, I am using an iFrame like below: But I don't know if linking to a specific page is possible or Google would like that because I tried the solutions posted on how to open specific page on Google's docs viewer and http://googlesystem.blogspot.com/2009/11/link-to-page-in-googles-document-viewer.html but all of them seem to be outdated. Is this even possible? Thanks for any help.

• jquery onclick function not firing with rails link_to_remote

  - by RahTha

  In the js file of the page, inside $(document).ready(function() {} i have $(".school a").live("click", function (e){ e.preventDefault(); ....; jsFunc(param1, param2, param3); }); Now the div with the class school has tags generated by rails link_to_remote with :url, :action, :before, :html. On clicking on this link it does all that it should do with regards to link_to_remote, but somehow the onclick event in the document.ready does not attach to it. Why would this be happening? The jsFunc all it does is post to a url async-ly, i figured out that stuffing that post url in the :before of the link_to_remote would work - but is there a more elegant way of just being able to use the attach functionality

• How do i handle a heavy page?

  - by Ulhas Tuscano

  I have been asked to design & develop a page in asp.net which contains 7 tabs.Each table contains 2 Editable gridview & clicking on gridview cell should open a popup & that popup will open a new popup ( I would say nested popup). even when i switch from one tab to another. It should hold the griddata & whenever user will finish all the operations he/she will click on save button which will save all the data contained in the tabs. The page is really too too too heavy. It will definitely take a long time to load as it contains gridview operations , popup related jobs, tab data & tab switching. I am finding the best way i can achieve this with an acceptable speed of operation. Any suggestions or help would be greatly appreciated.
