• is struts2 Framework dead? if so, which direction to go from here?

  - by Omnipresent

  I've been working in struts2 framework for the past year and a half. As I look around SO it seems like struts2 questions get the least amount of hits. At first I thought it was because the SO community is not much into struts2, but this is the case in other forums as well. Only the struts2 mailing list is pretty active. I think struts2 is slowly becoming a dinosaur framework and I want to move on. I've dabbled a little with other stuff like RoR, Grails, Django, .NET MVC but I've never really committed and made a pact with myself to sit down and learn these. Maybe its the fact that I dont know the languages that these frameworks are built on. Spending a day or two with RoR makes me want to choke some of the JAR files and struts2 html tags and .NET MVC looks promising but not knowing c# ties me back. My question is, have you been on the same path? Did anyone used to do struts2 before and now changed to something new? What would you suggest I learn after Struts2? And lastly, as a developer how do you motivate yourself to learn a new framework, or a language? for me, just typing the code provided in the book is dead boring.

• I want to merge two PostScript Documents, pagewise. How?

  - by Peter Miehle

  hello, i have a tricky question, so i need to describe my problem: i need to print 2-sided booklets (a third of a paper) on normal paper (german A4, but letter is okay also) and cut the paper afterwards. The Pages are in a Postscript Level 2 File (generated by an ancient printer driver, so no chance to patch that, except ps2ps) generated by me with the ancient OS's Printing driver facilities (GpiMove, GpiLine, GpiText etc). I do not want to throw away two-thirds of the paper, so my idea is: Take file one, two and three, merge them (how?) on new double-sided papers by translate/move file two and three by one resp. two thirds and print the resulting new pages. If it helps, I can manage to print one page of the booklet per file. I cannot "speak" postscript natively, but I am capable of parsing and merging and manipulating files programmaticly. Maybe you can hint me to a webpage. I've read through the manuals on adobe's site and followed the links on www.inkguides.com/postscript.asp Maybe there are techniques with PDF that would help? I can translate ps2pdf. Thanks for help Peter Miehle PS: my current solution: i.e. 8 pages: print page 1, 4 and 7 on page one, 2,5,8 on page two and 3,6,blank on page three, cut the paper and restack. But i want to use a electrical cutting machine, which works better with thicker stacks of paper.

• Switching between iScroll and standard WebView Scrolling functionality

  - by Jonathan

  I'm using iScroll 4 for my rather heavy iPhone web/Phonegap app and trying to find a way to switch between iScrolls scrolling functionality and standard "native" webview scrolling, basically on click. Why I want this is described below. My app has several different subpages all in one file. Some subpages have input fields, some don't. As we all know, iScroll + input fields = you're out of luck. I've wrapped iScrolls wrapper div (and all its functionality) around the one sub page where scrolling is crucial, and where there are no input fields. The other sections, I've simply placed outside this div, which gives these no scrolling functionality at all. I've of course tried wrapping all inside the wrapper and enabling/disabling scroll (shown below) but that didn't work me at all: myScroll.disable() myScroll.enable() By placing some sub pages outside the main scrolling area / iscroll div, I've disabled both iScrolls and the standard webview scrolling (the latter - which i guess iScroll does) which leaves me with only basic basic scrolling, hence basically no scrolling at all. One can move around vertically, but once you let go of the screen with, the "scrolling" stops. Quite naturally but alas so nasty. Therefore, I'm searching for a way to enable standard webview scrolling on the sub pages placed outside of iScroll's wrapper div. I've tried different approaches such as the one above and by using: document.removeEventListener('touchmove', preventDefault, false); document.removeEventListener('touchmove', preventDefault, true); But with no success. Sorry for not providing you guys with any hard code or demos to test out for yourselves, it's simply too much code and it would be presented so out of its context, nobody would be able to debug it. So, is there a way n javascript to do this, switching between iScroll scrolling functionality and standard "native" webview scrolling? I would rather not rebuild the entire DOM framework so a solution like the one described above would be preferable.

• LaTeX limitation?

  - by Jayen

  Hi, I've hit an annoying problem in LaTeX. I've got a tex file of about 1000 lines. I've already got a few figures, but when I try to add another figure, It barfs with: ! Undefined control sequence. <argument> ... \sf@size \z@ \selectfont \@currbox l.937 \begin{figure}[t] If I move the figure to other parts of the file, I can get similar errors on different lines: ! Undefined control sequence. <argument> ... \sf@size \z@ \selectfont \@currbox l.657 \paragraph {A Centering Algorithm} If I comment out the figure, all is ok. %\begin{figure}[t] % \caption{Example decision tree, from Reiter and Dale [2000]} % \label{fig:relation-decision-tree} % \centering % \includegraphics[keepaspectratio=true]{./relation-decision-tree.eps} %\end{figure} If I keep just the begin and end like: \begin{figure}%[t] % \caption{Example decision tree, from Reiter and Dale [2000]} % \label{fig:relation-decision-tree} % \centering % \includegraphics[keepaspectratio=true]{./relation-decision-tree.eps} \end{figure} I get: ! Undefined control sequence. <argument> ... \sf@size \z@ \selectfont \@currbox l.942 \end {figure} At first, I thought maybe LaTeX has hit some limit, and I tried playing with the ulimits, but that didn't help. Any ideas? i've got other figures with graphics already. my preamble looks like: \documentclass[acmcsur,acmnow]{acmtrans2n} \usepackage{array} \usepackage{lastpage} \usepackage{pict2e} \usepackage{amsmath} \usepackage{varioref} \usepackage{epsfig} \usepackage{graphics} \usepackage{qtree} \usepackage{rotating} \usepackage{tree-dvips} \usepackage{mdwlist} \makecompactlist{quote*}{quote} \usepackage{verbatim} \usepackage{ulem}

• How to improve the use of Delphi Frames

  - by Brian Frost

  I've used frames in Delphi for years, and they are one of the most powerful features of the VCL, but standard use of them seems to have some risk such as: It's easy to accidentally move or edit the frame sub-components on a frame's host form without realising that you are 'tweaking' with the frame - I know this does not affect the original frame code, but it's generally not what you would want. When working with the frame you are still exposed to its sub-components for visual editing, even when that frame is years old and should not be touched. So I got to thinking.... Is there a way of 'grouping' components such that their positions are 'locked'? This would be useful for finished forms as well as frames. Often other developers return code to me where only the form bounds have changed and even they did not intend any change. Is there any way of turning a frame and its components into a single Delphi component? If so, the frame internals would be completely hidden and its useability would increase further. I'm interested in any thoughts... Brian.

• Turing Model Vs Von Neuman model

  - by Santhosh

  First some background (based on my understanding).. The Von-Neumann architecture describes the stored-program computer where instructions and data are stored in memory and the machine works by changing it's internal state, i.e an instruction operated on some data and modifies the data. So inherently, there is state msintained in the system. The Turing machine architecture works by manipulating symbols on a tape. i.e A tape with infinite number of slots exists, and at any one point in time, the Turing machine is in a particular slot. Based on the symbol read at that slot, the machine change the symbol and move to a different slot. All of this is deterministic. My questions are Is there any relation between these two models (Was the Von Neuman model based on or inspired by the Turing model)? Can we say that Turing model is a superset of Von Newman model? Does functional Programming fit into Turing model. If so how? (I assume FP does not lend itself nicely to the Von Neuman model)

• Why does Cut/Paste of form components sometimes stop working in Delphi 2007 IDE?

  - by robsoft

  This is driving me crazy. I'm not going to take it anymore. I'm going to ask, even at the risk of eternal public humiliation! (If it's something really obvious or that I've done to the system myself). For reasons I've never quite had the patience to work out, every so often the form I'm working on in Delphi 2007's visual form editor goes 'pseudo-read-only'; I can add new components to the form, I can move/resize existing ones (and change any properties in the Object Inspector), and I can select a component and 'copy' it to the clipboard. But I'm completely unable to cut a component from the form, or paste a new copy down. I don't believe it's to do with the 'Lock Controls' Edit menu option as I can toggle this on or off and it has the effect it's supposed to - this disappearance of Cut & Paste happens on the right-click context menu, from the keyboard and from the main Edit menu - it's as if the form has become read only to thing to do with the clipboard. If I close the form in the IDE and then reopen it, everything starts working fine again (just as D1, D3, D5 and D7 always did for me, previously). I'm not going mad, as I'm sure I read something about why this happens on a newsgroup once and it's caught me out from time to time many many times in the last few months, but I've failed to find the newsgroup reference this evening and I've decided that, as more and more Delphi users seem to be making use of StackOverflow, it was worth asking here. Help - when I'm doing lots of form-work it drives me absolutely mad!

• Silverlight 4, Out of browser, Printing, Automatic updates

  - by minal

  I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

• Google Map GEO Results

  - by Lee

  Hey All I'm getting really frustrated with google geo results and hope someone can advise me the best was to go. I have created a AutoSuggest feature where you can start typing the address and google will repspond with suggestions. User then selects and address to move on. But before I want them to continue on the next page I want to validate their selection. I would have thought this will be easy as we are only checking against what google has already given. But when I do my validation lookup it displays no results. Some example code: Lets say I picked from the suggestion this address: Suffield, CT 06078, USA Then on validation I do a second lookup with this address ie. $string = "Suffield, CT 06078, USA"; echo 'http://maps.google.com/maps/geo?output=json&oe=utf8&gl=us&sensor=false&key=[MyKey]&q='.urlencode($string).''; It gives me Error code 602 (G_GEO_UNKNOWN_ADDRESS) How can it not be found when its given me the address ?? Any suggestions how I can get around this. Hope you can !

• Why ComboBox hides cursor when DroppedDown is set?

  - by Ivan Danilov

  Let's create WinForms Application (I have Visual Studio 2008 running on Windows Vista, but it seems that described situation takes place almost everywhere from Win98 to Vista, on native or managed code). Write such code: using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public class Form1 : Form { private readonly Button button1 = new Button(); private readonly ComboBox comboBox1 = new ComboBox(); private readonly TextBox textBox1 = new TextBox(); public Form1() { SuspendLayout(); textBox1.Location = new Point(21, 51); button1.Location = new Point(146, 49); button1.Text = "button1"; button1.Click += button1_Click; comboBox1.Items.AddRange(new[] {"1", "2", "3", "4", "5", "6"}); comboBox1.Location = new Point(21, 93); AcceptButton = button1; Controls.AddRange(new Control[] {textBox1, comboBox1, button1}); Text = "Form1"; ResumeLayout(false); PerformLayout(); } private void button1_Click(object sender, EventArgs e) { comboBox1.DroppedDown = true; } } } Then, run app. Place mouse cursor on the form and don't touch mouse anymore. Start to type something in TextBox - cursor will hide because of it. When you press Enter key - event throws and ComboBox will be dropped down. But now cursor won't appear even if you move it! And appears only when you click somewhere. There I've found discussion of this problem. But there's no good solution... Any thoughts? :)

• Why can a struct defined inside a function not be used as functor to std::for_each?

  - by Oswald

  The following code won't compile. The compiler complains about *no matching function for call to for_each*. Why is this so? #include <map> #include <algorithm> struct Element { void flip() {} }; void flip_all(std::map<Element*, Element*> input) { struct FlipFunctor { void operator() (std::pair<Element* const, Element*>& item) { item.second->flip(); } }; std::for_each(input.begin(), input.end(), FlipFunctor()); } When I move struct FlipFunctor before function flip_all, the code compiles. Full error message: no matching function for call to ‘for_each(std::_Rb_tree_iterator<std::pair<Element* const, Element*> >, std::_Rb_tree_iterator<std::pair<Element* const, Element*> >, flip_all(std::map<Element*, Element*, std::less<Element*>, std::allocator<std::pair<Element* const, Element*> > >)::FlipFunctor)’

• How many files in a directory is too many?

  - by Kip

  Does it matter how many files I keep in a single directory? If so, how many files in a directory is too many, and what are the impacts of having too many files? (This is on a Linux server.) Background: I have a photo album website, and every image uploaded is renamed to an 8-hex-digit id (say, a58f375c.jpg). This is to avoid filename conflicts (if lots of "IMG0001.JPG" files are uploaded, for example). The original filename and any useful metadata is stored in a database. Right now, I have somewhere around 1500 files in the images directory. This makes listing the files in the directory (through FTP or SSH client) take a few seconds. But I can't see that it has any affect other than that. In particular, there doesn't seem to be any impact on how quickly an image file is served to the user. I've thought about reducing the number of images by making 16 subdirectories: 0-9 and a-f. Then I'd move the images into the subdirectories based on what the first hex digit of the filename was. But I'm not sure that there's any reason to do so except for the occasional listing of the directory through FTP/SSH.

• Question about 'git branching'

  - by michael

  Hi, I read this about git branch: http://book.git-scm.com/3_basic_branching_and_merging.html so I follow it and create 1 branch : experimental And I 1. switch to experimental branch (git checkout experimental) 2. make a bunch of changes 3. commit it (git commit -a) 4. switch to master branch (git checkout master) 5. make some changes and commit there 6. switch back to experimental (git checkout experimental) 7. merge master change to experimental (git merge master) 8. there are some conflicts but after I resolve them, I did 'git add myfile' And now i am stuck, I can't move back to master when I do $ git checkout master error: Entry 'res/layout/my_item.xml' would be overwritten by merge. Cannot merge. and I did: $ git rebase --abort No rebase in progress? and I did : $ git add res/layout/socialhub_list_item.xml $ git checkout master error: Entry 'res/layout/my_item.xml' would be overwritten by merge. Cannot merge. What can I do so that I can go back to my master branch? Thank you.

• externalizing junit stub objects.

  - by Ajay

  Hi!    In my project we created stub files for testing junits in java(factories) itself. However, we have to externalize these stubs. After seeing a number of serializers/deserializers, we settled on using XStream to serialize and deserialize these stub objects. XStream works like a charm. Its pretty good at what it claims to be. Previously, we had a single factory class say AFactory which produced all the stubs needed for testing different test cases. Now when externalizing each of the stub generated, we hit a road block. We had to create 1 xml file for each stub produced by the factory. For example, public final class AFactory{ public static A createStub1(){ /*Code here */} public static A createStub2(){ /*Code here */} public static A createStub3(){ /*Code here */} } Now, when trying to move this stubs to external files, we had to create 1 xml file for each stub created(A-stub1.xml, A-stub2.xml and A-stub3.xml). The problem with this approach is that, it leads to proliferation of xml stub files. I was thinking, how about keeping all the stubs related to a single bean class in a single xml file. <?xml version="1.0"?> <stubs class="A"> <stub id="stub1"> <!-- Here comes the externalized xml stub representation --> </stub> <stub id="stub2"> </stub> </stubs> Is there a framework which allows you keep all the stub in xml representation in a single xml file as above ? Or What do you guys suggest should be the right approach to adhere to ?

• What is the best practice for ouputting data from a collection on an ASP.net Page?

  - by bshacklett

  I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code: <% Dim objs as ArrayList = New ArrayList() For i = 0 To 2 Dim obj as Obj = New Obj() obj.setProp1("ASDF") obj.setProp2("FDSA") objs.Add(obj) Next i %> <table> <thead> <tr> <th scope="col">Property 1</th> <th scope="col">Property 2</th> </tr> </thead> <tbody> <% For Each obj As Obj In objs Dim objProp1 As String = obj.getProp1 Dim objProp2 As String = obj.getProp2 %> <tr> <td><% Response.Write(objProp1)%></td> <td><% Response.Write(objProp2)%></td> </tr> <% Next %> </tbody> </table> What is the ".net" way of doing this?

• String trouble in Rave Reports 8

  - by Jørn E. Angeltveit

  We are currently working with Delphi 2006, but we are now very ready to move on to Delphi 2010. The problem lies in our Rave reports, though... We just get to many string errors when running our reports with Rave 8. And they just don't make any sense. (The reports compile with no error, and we can even run them without any error in Rave 6.) For instance: //This event causes access violation (in rtl14.bpl) at run time { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)) + ' and then some more'; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; //This event works OK { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)); // + ' and then some more'; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; //This event works OK too { Event for Page1.OnBeforeReport } function Page1_OnBeforeReport(Self: TRavePage); var s: String; begin s := 'My text in param'; s := s + ' and som more text'; s := copy(s,1,length(s)) + s; RaveProject.SetParam('MyTestParam', s); end OnBeforeReport; We really want to stick to Rave, because we have a lot of reports (150+) with a lot of functionality (sql statements, events etc). Besides, we have customers who have designed their own custom reports as well. Does anybody know the reason for these errors? Is there any solution or workaround to these problems?

• How can I make an AJAX link work once it is moved out of the iFrame?

  - by KcYxA

  Hi, I am using an iFrame with a form that return some content with an AJAX link. I am then moving the returned content out of the iFrame into the main page. However, then the ajax link does not work and the error "Element is null" is created once the link is clicked. How can I move content from the iFrame and still have the AJAX link working? Here's the code returned by the iFrame: <span id="top"> <a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7"> <img src="/img/delete.bmp"/> </a> <script type="text/javascript"> parent.Event.observe('link8', 'click', function(event) { new Ajax.Updater('top','/item_pictures/delete/3', { asynchronous:true, evalScripts:true, onCreate:function(request, xhr) { document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">"; }, requestHeaders:['X-Update', 'top'] }) }, false); </script> </span>

• Java FileLock for Reading and Writing

  - by bobtheowl2

  I have a process that will be called rather frequently from cron to read a file that has certain move related commands in it. My process needs to read and write to this data file - and keep it locked to prevent other processes from touching it during this time. A completely separate process can be executed by a user to (potential) write/append to this same data file. I want these two processes to play nice and only access the file one at a time. The nio FileLock seemed to be what I needed (short of writing my own semaphore type files), but I'm having trouble locking it for reading. I can lock and write just fine, but when attempting to create lock when reading I get a NonWritableChannelException. Is it even possible to lock a file for reading? Seems like a RandomAccessFile is closer to what I need, but I don't see how to implement that. Here is the code that fails: FileInputStream fin = new FileInputStream(f); FileLock fl = fin.getChannel().tryLock(); if(fl != null) { System.out.println("Locked File"); BufferedReader in = new BufferedReader(new InputStreamReader(fin)); System.out.println(in.readLine()); ... The exception is thrown on the FileLock line. java.nio.channels.NonWritableChannelException at sun.nio.ch.FileChannelImpl.tryLock(Unknown Source) at java.nio.channels.FileChannel.tryLock(Unknown Source) at Mover.run(Mover.java:74) at java.lang.Thread.run(Unknown Source) Looking at the JavaDocs, it says Unchecked exception thrown when an attempt is made to write to a channel that was not originally opened for writing. But I don't necessarily need to write to it. When I try creating a FileOutpuStream, etc. for writing purposes it is happy until I try to open a FileInputStream on the same file.

• Visual Studio 2008 project organization for executable and assembly

  - by user304582

  Hi - I am having a problem setting up the following in Visual Studio 2008: a parent project which includes the entrypoint Main() method class and which declares an interface, and a child project which has classes that implement the interface declared in the parent project. I have specified that Parent's Output type is a Console application, and Child's Output type is a Class library. In Child I have add a reference to the Parent as a project, and specified that Child depends on Parent and that the build order should be Parent, then Child. The build succeeds, and as far I can tell, the right things show up in the Child/bin/debug directory: Parent.exe and Child.dll. However, if I run Parent.exe, then at the point when it should load a class from the Child.dll, it fails with the error message: exception executing operation System.TypeLoadException: Could not load type 'Child.some.class' from assembly 'Parent, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. I guess I'm confused as to how to get the Parent and Child projects to play together. I plan on having more child projects that use the same framework that is set up in the Parent, and so I do not want to move the entrypoint class down into the Child project. If I try to specify that the Child project is also a Console application, then the build process fails because there is no Main() entrypoint class in the child (even though the Parent project is included as a reference). Any help would be welcome! Thanks, Martin

• Junit: splitting integration test and Unit tests.

  - by jeff porter

  Hello all, I've inherited a load of Junit test, but these tests (apart from most not working) are a mixture of actual unit test and integration tests (requiring external systems, db etc). So I'm trying to think of a way to actually separate them out, so that I can run the unit test nice and quickly and the integration tests after that. The options are.. 1: Split them into separate directories. 2: Move to Junit4 and annotate the classes to separate them. 3: Use a file naming convention to tell what a class is , i.e. AdapterATest and AdapterAIntergrationTest. 3 has the issue that Eclipse has the option to "Run all tests in the selected project/package or folder". So it would make it very hard to just run the integration tests. 2: runs the risk that developers might start writing integration tests in unit test classes and it just gets messy. 1: Seems like the neatest solution, but my gut says there must be a better solution out there. So that is my question, how do you lot break apart integration tests and proper unit tests?

• position content relative to a fluid width element set to position:fixed

  - by Star

  I have a layout with the following requirements An image on the left side, and content on the right side. The image is pinned to the bottom left of the viewport The image does not move when the user scrolls The image resizes to 100% height of the viewport, up to it's max height. (I don't want the image to distort in it's attempts to be larger than it actually is) The image retains it's aspect ratio, and resizes it's width according to the height resizing. The content begins to the right of the image, and moves as the image resizes with the browser viewport. Now, I've managed to achieve pretty much all but the last of these requirements. Have a look here: http://letteringmusic.com/ The image resizes quite nicely, but I can't get the content to float next to the image because image is position:fixed, and therefore out of the document flow. I'm not opposed to a javascript solution if that's the only way to get the result I want. Anybody know what I need to do to make this work? Thank you!!

• Reading Xml with XmlReader in C#

  - by Gloria Huang

  I'm trying to read the following Xml document as fast as I can and let additional classes manage the reading of each sub block. <ApplicationPool><Accounts><Account><NameOfKin></NameOfKin><StatementsAvailable><Statement></Statement></StatementsAvailable></Account></Accounts></ApplicationPool> I can't seem to format the above nicely :( However, I'm trying to use the XmlReader object to read each Account and subsequently the "StatementsAvailable". Do you suggest using XmlReader.Read and check each element and handle it? I've thought of seperating my classes to handle each node properly. So theres an AccountBase class that accepts a XmlReader instance that reads the NameOfKin and several other properties about the account. Then I was wanting to interate through the Statements and let another class fill itself out about the Statement (and subsequently add it to an IList). Thus far I have the "per class" part done by doing XmlReader.ReadElementString() but I can't workout how to tell the pointer to move to the StatementsAvailable element and let me iterate through them and let another class read each of those proeprties. Sounds easy!

• How do I manage application configuration in ASP.NET?

  - by GlennS

  I am having difficulty with managing configuration of an ASP.Net application to deploy for different clients. The sheer volume of different settings which need twiddling takes up large amounts of time, and the current configuration methods are too complicated to enable us to push this responsibility out to support partners. Any suggestions for better methods to handle this or good sources of information to research? How we do things at present: Various xml configuration files which are referenced in Web.Config, for example an AppSettings.xml. Configurations for specific sites are kept in duplicate configuration files. Text files containing lists of data specific to the site In some cases, manual one-off changes to the database C# configuration for Windsor IOC. The specific issues we are having: Different sites with different features enabled, different external services we have to talk to and different business rules. Different deployment types (live, test, training) Configuration keys change across versions (get added, remove), meaning we have to update all the duplicate files We still need to be able to alter keys while the application is running Our current thoughts on how we might approach this are: Move the configuration into dynamically compiled code (possibly Boo, Binsor or JavaScript) Have some form of diffing/merging configuration: combine a default config with a live/test/training config and a site-specific config

• Crystal Reports .Net Guidance

  We have been using .Net and Visual Studio for the last six years, and early on developed a number of web based reporting applications using the .Net version of Crystal Reports that was bundled with Visual Studio. My overall opinion of that product has been, to say the least, rather unimpressed. It seemed to be incredibly difficult and convoluted to use, we had to make security changes, install various extra software, and so on. Now, we are moving to VS2008 and version 3.5 of the .Net framework, and the time has come to redevelop some of these old applications. The developers who used (and somehow mastered) Crystal .Net have long gone, and I am facing a decision - do we stick with Crystal Reports or move to something else. We also have the "full" version of Crystal Reports XI at our disposal. The way we use the product is to product pdf versions of data extracted from various databases. While some apps use the inbuilt Crystal Reports viewer as well, this seems to be redundant now with the flexibility of grid views - but there is still the need to produce a pdf version of the data in teh grid for printing, or in Excel format to download. What is the concensus? Is Crystal Reports .Net worth persisting with, or should we work out how to use version XI? Alternatively, is there a simple and low cost way to generate pdf reports without using Crystal? What good sources of "how to" information have others found and recommend? Are there suitable books, designed for VS2008 / .Net 3.5 development that you have used and found of benefit? Thanks in advance.

• JQUERY: Setting Active state on animated menu tabs

  - by Tony

  I have image sprites that use JQuery to set the BG position on mouseover and mouseout events. When I set the active state BG position using JQUERY it works fine until I move my cursor away from the active 'tab' which then fires the mouseout event animation. What I want is the mouseClick event to stop the animation on the active tab but still allow the animation effect to work on the other tabs, and when another tab is clicked for the active state to be removed from the current tab to the new 'active' tab. JQuery $(function(){ /* This script changes main nav links hover state*/ $('.navigation a') .css( {backgroundPosition: "-1px -120px"} ) .mouseover(function(){ $(this).stop().animate({backgroundPosition:"(-1px -240px)"}, {duration:400}) }) .mouseout(function(){ $(this).stop().animate({backgroundPosition:"(-1px -120px)"}, {duration:400, complete:function (){ $(this).css({backgroundPosition: "-1px -120px"}) }}) }) }); $(document).ready(function(){ $("a").click(function(){ $(this).css({backgroundPosition: "-1px -235px"}); }); }); HTML <ul class="navigation"> <li><a href="#index" tabindex="10" title="Home" id="homeButton"></a></li> <li><a href="#about" tabindex="20" title="About us" id="aboutButton"></a></li> <li><a href="#facilities" tabindex="30" title="Our facilities and opening Times" id="facilitiesButton"></a></li> <li><a href="#advice" tabindex="40" title="Advice and useful links" c id="adviceButton"></a></li> <li><a href="#find" tabindex="50" title="How to find Us" id="findButton"></a></li> <li><a href="#contact" tabindex="60" title="Get in touch with us" id="contactButton"></a></li> </ul> You can see what I've got so far here Thanks in advance for any help
