• trying to decide between asp.net and jsp

  - by Amir

  Hey Guys, I am wondering if anyone can shed some lights on the situation. I am about to start a project and trying to figure out what solution is best to go with asp.net or java jsp pages I have personally worked alot with .net and am really happy with the framework and Visual studio as IDE I find it easy to work with and there is a massive community support behind .net, i can get alot done quickly I have not every written anything use java jsp, there will be a learning curve here , so my experience is limited here. however after seeing jira i am very impressed with its capabilities, it has changed alot since the old days ( java 1.2 ) that i used to work with, and the fact that it runs under linux is a huge plus, so i am trying to decide is the learning curve, worth the price ? so given the situation above what would you recommended? Thanks, Amir

• What does the obscure javascript error b(e.target).zIndex is not a function mean?

  - by stormist

  To give more information I am using the modular form here: http://jqueryui.com/demos/dialog/#modal-form b(e.target).zIndex is not a function [Break on this error] (function(a){a.widget("ui.mouse",{opti...is._unrotate}return this}})})(jQuery); /js/jquery-ui.min.js I also seem to be getting the error "Too much recursion" too much recursion [Break on this error] 3||a.nodeType===8)){if(a.setInterval&&...this.special[o]||{};if(!t){t=e[o]={}; https://my.dev.peer1.com/js/jquery/jquery-1.4.min.js I know its not much to go on but I was hoping someone might have experience with similar issues.

• How do I manage library symbols with linked classes in Flash CS4 to compile/debug in Flash Builder 4

  - by wpjmurray

  I'm building a video player using Flash CS4 (hereby referred to as "Flash") to create the graphic symbols and compiling and debugging with Flash Builder 4 ("FB4"). Here are the steps I take in my current workflow: --Create the graphic symbols in Flash. I've created a few different symbols for the player, but I'll focus on just the play/pause button ("ppbutton") here. --In the Library panel, I go to the ppbutton symbol's Linkage properties and link to a class named assets.PlayPauseButtonAsset that extends MovieClip. I do not actually have an assets package nor do I have a class file for PlayPauseButtonAsset as Flash will create them for me when I publish. --In Flash's Publish settings, I set the project to export a SWC that will be used in FB4, called VideoPlayerAssets.swc. --After the SWC is created, I create my FB4 project called "VideoPlayer" and add the SWC to my path. FB4 creates the class VideoPlayer in the default package automatically. --In VideoPlayer.as, I import assets.*, which imports all of the symbol classes I created in Flash and are available via VideoPlayerAssets.swc. I can now instantiate the ppbutton and add to the stage, like this: var ppbutton:PlayPauseButtonAsset = new PlayPauseButtonAsset(); addChild(ppbutton); At this point ppbutton doesn't have any functionality because I didn't create any code for it. So I create a new class called video.controls.PlayPauseButtonLogic which extends assets.PlayPauseButtonAsset. I add some logic, and now I can use that new class to put a working ppbutton on the stage: var ppbutton:PlayPauseButtonLogic = new PlayPauseButtonLogic(); addChild(ppbutton); This works fine, but you may be asking why I didn't just link the ppbutton symbol in Flash to the video.controls.PlayPauseButtonLogic class in the first place. The reason is that I have a designer creating the UI in Flash and I don't want to have to re-publish the SWC from Flash every time I make a change in the logic. Basically, I want my designer to be able to make a symbol in Flash, link that symbol to a logically named class in Linkage properties, and export the SWC. I do not want to have to touch that .fla file again unless the designer makes changes to the symbols or layout. I'm using a versioning system for the project as well and it's cleaner to make sure only the designer is touching the .fla file. So, finally, here's the issue I'm running into: --As the design gets more complex, the designer is nesting symbols to position the video controls on the control bar. He creates a controlbar symbol and links it to assets.ControlBarAsset. The controlbar symbol contains the ppbutton symbol. --The designer publishes the SWC and ControlBarAsset is now available in FB4. I create new class called video.controls.ControlBarLogic that extends assets.ControlBarAsset so I can add some logic to the controlbar, and I add the controlbar to the stage: var controlbar:ControlBarLogic = new ControlBarLogic(); addChild(controlbar); --This works, but the ppbutton doesn't do anything. That's because ppbutton, while inside controlbar, is still only linked to PlayPauseButtonAsset, which doesn't have any logic. I'm no longer instantiating a ppbutton object because it's part of controlbar. That's where I'm stuck today. I can't seem to simply re-cast controlbar's ppbutton as PlayPauseButtonLogic as I get a Type error. And I don't want to have to make a class that has to instantiate each of the video player controls, the place them at their x and y values on the stage according to how the designer placed them, as that would require me to open the .fla and check the various properties of a symbol, then add those values to the code. If the designer made a change, I'd have to go into the code each time just to update those properties each time. Not good. How do I re-cast nested symbols to use the logic classes that I create that extend the asset classes? Remember, the solution is not to link Flash symbols to actual classes so I don't have to keep recompiling the SWC, unless there's a way to do that without having to re-compile the SWC. I want the designer to do his thing, publish the SWC, and be done with it. Then I can take his SWC, apply my logic to his assets, and be able to debug and compile the final SWF.

• SQL Server database backup: Network Service file access

  - by Keith Maurino

  When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder. BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak' My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to? NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.

• Entity Framework Vote of No Confidence - relevant in .NET 4?

  - by Asaf R

  Hi, I'm deciding on an ORM for a big project and was determined to go for ADO.NET Entity Framework, specifically its new version that ships with .NET 4. During my search for information on EF I stumbled upon ADO .NET Entity Framework Vote of No Confidence which I'm not sure how to take. The Vote of No Confidence was written sometime in 2008 to convince Microsoft to listen to specific criticism for EF v1. It's not clear whether the claims made in the Vote of No Confidence are still valid (in .NET 4) and if they're serious enough to use other solutions. NHibernate is a mature alternative, but I don't know what problems it brings. I'm generally more inclined towards a Ms solution, mainly because I can count on integration with VS and on their developer support. I would appreciate examples of how the problems mentioned in the Vote of No Confidence affect in real world projects. More importantly, are the claims made there still relevant in EF for .NET 4? Thanks, Asaf

• How to implement SAML SSO

  - by A_M

  How is SAML SSO typically implemented? I've read this about using SAML with Google Apps, and the wikipedia entry on SAML. The wikipedia entry talks about responding with forms containing details of the SAMLRequest and SAMLResponse. Does this mean that the user has to physically submit the form in order to proceed with the single sign on? The google entry talks about using redirects, which seems more seemless to me. However, it also talks about using a form for the response which the user must submit (although it does talk about using JavaScript to automatically submit the form). Is this the standard way of doing this? Using redirects and JavaScript for form submission? Does anyone know of any other good resources about how to go about implementing SSO between a Windows Domain and a J2EE web application. The web application is on a separate network/domain. My client wants to use CA Siteminder (with SAML).

  I create a child console application with _process = new Process(); _process.StartInfo.FileName = @"cmd.exe"; _process.StartInfo.UseShellExecute = false; _process.StartInfo.RedirectStandardInput = true; _process.StartInfo.RedirectStandardOutput = true; _process.StartInfo.CreateNoWindow = true; _proccess.Start(); Now I can go to c:\aaa _process.StandardInput.Write("cd c:\\aaa\xD\xA"); But normally user can type c:\ + TAB + ENTER. How can I do the same? This does not work: _process.StandardInput.Write("cd c:\\\0x9\xD\xA");

• avaudioplayer interferes with mpmovieplayer on ipad

  - by user175826

  my app plays video and audio. however, i have a problem where once i play an audio file using avaudioplayer, the video refuses to play. when i play the video first, everything is fine. but if the audio is played first, any time i try to play the video it simply pops up the video player but will not play the actual video (you can use the scroller to go to any point in the video, but no playback will happen). this issue does not come up on the iphone, nor on the ipad simulator. clearly there is some resource conflict here, probably related to the audio, and i'd welcome some input on how to address it.

• phantom error "error parsing XML: unbound prefix"

  - by Brad Hein

  The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check). My environment is: Fedora Eclipse Platform Version: 3.4.2 Based on build id: 20090211-1700 My target is Android API level 5. The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error. Screenshot: http://i50.tinypic.com/2i89iee.jpg Who should I report this to?

• How to create multiple SOAP webservice clients in same netbeans 6.8 project

  - by James Black

  I have a project that is largely just to help one application make connections to an SAP server, for real-time updates. So the first web service client works fine, but I try to create a second and it seems to hang and I expect part of the problem is that it is trying to create a new Service class, but the namespace for all the webservices are identical, but the wsdl is obviously different, so it can't create the client. I can do it manually, by just having Service1, Service2, etc, or making some other change, but the issue is that Netbeans should be able to do this easily. I can't use Eclipse as the wsimport parameters that Netbeans uses works, in Eclipse I would need to do too much to make it work, so I will go with the easier tool. I don't want to create a new project for each webservice, as that just seems to be perpetuating a design error. So, how can I easily create multiple webservice clients that will all have the same target namespace, using Netbeans 6.8+?

• Establish draggable content constraints depending on position

  - by drukelly

  Asking all jQuery experts! How would I go about setting up constraints for a draggable element depending on its positioning? I have a basic example here. I thought it would be as simple as adding an option, containment. Ideally, I want it to drag within the following box: top: 0px left: 0px top: -263px left: -272px top: 0px left: -272px top: -263px left: 0px Is there a way to drag the element within the parameters above so you don't the extra white space? I appreciate the help!

• Is NetNamedPipeBinding binding guaranteed to work only on the same machine?

  - by Asaf R

  Hi, I've created a Windows Service that uses WCF for communications to it. The service should be used be called only from the same machine. If I can guarantee that there's no way to communicate with it from another machine, I can consider it secured. Since I'm using communications on a single machine, I opted to used NetNamedPipeBinding. This bindings documentation says it's Optimized for on-machine communications, but does not give any guarantees. My questions is, does NetNamedPipeBinding provide on-machine-only guarantees? If not what binding does, or how would you go implementing a custom bindings that does provide such guarantees? Thanks, Asaf

• Do not fetch app.manifest each time

  - by Kristof

  For creating an offline version of a bunch of linked web pages I use an app.manifest-file that lists all the web pages for offline caching. I would like it that the app.manifest file is not fetched every time when a user jumps from one web page to another. Most of the web pages will never be updated once the application is on the iPhone. Also the target audience is abroad so roaming costs could add up while users are using my "web app". Searching the internet made me think in the direction of forcing an offline mode in Mobile Safari using Javascript but I don't know if this is the right way to go or if it is even possible. Does anyone have any other and/or better ideas and suggestions on how to do this?

• I want to port my delicious bookmarks to my website

  - by puneet

  I started building a app that will automatically download my delicious bookmarks, and save to a database, so they I can view them on my own website in my favoured format. I am forced to use oAuth, as I have a yahoo id to login to delicious. The problem is I am stuck at the point where oAuth requires a user to manually go and authenticate. Is there a code/ guidelines available anywhere I can follow? All I want is a way to automatically save my bookmarks to my database. Any help is appreciated. I can work on java, .net and php. Thanks.

• Consuming an iCal/.ics file in YQL

  - by Josh

  How would one consume an iCal/.ics file in YQL? Given an .ics such as: http://www.hebcal.com/export/ba/8a35a5efbb27548bc0272b94b8de96.ics?subscribe=1&v=1&year=2010&month=x&nh=on&tag=fp.ql&c=off How would I go about using YQL to select certain events based on fields, etc. I've tried the standard formats, and the only format that seems to even parse the file is HTML - which puts it all in a <p>, and removes the line returns that give the file meaning. I've had some success with using Yahoo Pipes' Fetch Feed Source, but was wondering if it's possible to do this entirely in YQL. Any ideas?

• What URL scheme would be better for "nested" resources in a RESTful application?

  - by Luke404

  Let's say we want a RESTful web service to manage some logically nested resources, where each instance of resource 'B' is logically contained by an instance of resource 'A'. The first example that comes to mind, working as a sysadmin, is email accounts and their domains: [email protected] [email protected] [email protected] ... What URL scheme would you suggest? At first I'd try: /domain/[domainname] /domain/[domainname]/account/[accountname] is that in line with RESTful principles? or should I go with something like: /domain/[domainname] /account/[account@domainname]/ or anything else?

• Project Active Executable can no longer be iPhone 3.2

  - by Rudiger

  I don't know how much you can help me because its under the NDA, but I recently updated to the OS 4 beta 3 xcode version. My project worked fine under 3.2 but under 4.0 parts are a not quite right I assume because it is still being developed. Every other installation of the beta sdk I could go into the project settings and select the iPhone 3.2 sdk and then change the target iPhone OS in the top left of Xcode but not this one. If I select 3.2 it still loads on 4.0 it seems I only have the 4.0 simulator. Under Active Target there is only 4.0. Any ideas how to get the 3.2 Simulator back?

• Is there a suggested solution structure for ASP.NET MVC Production Apps

  - by Eoin Campbell

  In general, I don't like to keep code (BaseClasses or DataAccess Code) in the App_Code directory of an ASP.NET Site. I'll usually pull this stuff out into a MySite.BusinessLogic & MySite.DataAccess DLL's respectively. I'm wondering should I be doing the same for ASP.NET MVC. Would it be better to Organise the solution something along the lines of MySite.Common - DLL - (Basic Functionality built on .NET System Dlls) MySite.DAL - DLL - (DataAccessLayer & DBML Files) MySite.Models - DLL - (MVC Models e.g. Repository Classes) MySite.Controllers - DLL (MVC Controllers which use Models) MySite - ASP.NET MVC Site. Or am I missing something... presumably, I'll lose some of the nice (Add View, Go To Controller, context menu items that have been added)

• WPF: Setting toolbar button sizes using a Style

  I have buttons on a toolbar in WPF. When I do the XAML: <ToolBar.Resources> <Style TargetType="{x:Type Button}"> <Setter Property="Width" Value="21"></Setter> <Setter Property="Height" Value="21"></Setter> </Style> </ToolBar.Resources> None of the buttons on the toolbar set their sizes accordingly. I have to go to each button and manually set their widths and heights to the desired values. Any idea why the Style on the toolbar does not work?

• Silverlight running in IE kiosk mode

  - by JimmySavile

  Hi, We are having a weird problem where by we are running a silveright application in IE8 kiosk mode, the shortcut is added to windows startup. The silverlight app runs on localhost. It all works fine until you reboot, IE displays "navigation to the webpage was canceled" when it loads. Yet the shortcut works fine, if you close IE and manually go into the startup folder and run the shortcut, or run the same shortcut from the desktop. I assume there is some sort of timing issue but have no idea what. Tried using 127.0.0.1 instead of localhost incase DNS hadn't been properly initialised at that point or something. Maybe an IIS initialisation problem? Anyone have any ideas? Thanks for your time

• MbUnit (gallio) and Visual Studio.Net Tests Not Completing or Debugging

  - by Davy

  Hi I'm using Gallio\MbUnit 3.1 with ReSharper and Visual Studio 2008. Everything is working well except this type of test: [Test] [Row("test@badEmail@_test.com")] [Row("test@badEmail@_test.")] public void IsValidEmail_Invalid_Emails_Should_Return_False(string invalidEmail) { Assert.IsFalse(AppHelper.IsValidEmail(invalidEmail), "Email validation failed for " + invalidEmail); } The test doesn't complete or go in to debug mode only when I pass in a parameter E.g. 'string invalidEmail'. If I remove that prameter it seems to work normally. It will run the test if I have: [Test] public void IsValidEmail_Invalid_Emails_Should_Return_False() { var invalidName = test@badEmail@_test.com"; Assert.IsFalse(AppHelper.IsValidEmail(invalidEmail), "Email validation failed for " + invalidEmail); } I appreciate that there may be better ways to achieve this test but I'm trying to work my way through a book and this is how it's explaining things. Any help is appreciated. Davy

• How do I get the "Install Missing Plugin" yellow bar to appear in firefox when flash is not installe

  - by Janak

  My rails website uses the open_flash_graph plugin to generate flash graphs for my clients. If a customer doesn't have flash installed, it doesn't display any messages, it simply doesn't show any graphs. I've noticed that if I go to other websites that need flash, I get a yellow bar at the top of my firefox window that offers to "Install Missing Plugin". I assume something in the HTML lets firefox know that this webpage needs flash. What code do I need to add to my website to make this work?

• Finding specific pixel colors of a BitmapImage

  - by Andrew Shepherd

  I have a WPF BitmapImage which I loaded from a .JPG file, as follows: this.m_image1.Source = new BitmapImage(new Uri(path)); I want to query as to what the colour is at specific points. For example, what is the RGB value at pixel (65,32)? How do I go about this? I was taking this approach: ImageSource ims = m_image1.Source; BitmapImage bitmapImage = (BitmapImage)ims; int height = bitmapImage.PixelHeight; int width = bitmapImage.PixelWidth; int nStride = (bitmapImage.PixelWidth * bitmapImage.Format.BitsPerPixel + 7) / 8; byte[] pixelByteArray = new byte[bitmapImage.PixelHeight * nStride]; bitmapImage.CopyPixels(pixelByteArray, nStride, 0); Though I will confess there's a bit of monkey-see, monkey do going on with this code. Anyway, is there a straightforward way to process this array of bytes to convert to RGB values?
