  • How to perform ant path mapping in war task?

    - by eljenso
    I have several JAR file pattern sets, like <patternset id="common.jars"> <include name="external/castor-1.1.jar" /> <include name="external/commons-logging-1.2.6.jar" /> <include name="external/itext-2.0.4.jar" /> ... </patternset> I also have a war task containing a lib element: ... Like this however, I end up with a WEB-INF/lib containing the subdirectories from my patterns: WEB-INF/lib/external/castor-1.1.jar WEB-INF/lib/external/... Is there any way to flatten this, so the JAR files appear top-level under WEB-INF/lib, regardless of the directories specified in the patterns? I looked at mapper but it seems you cannot use them inside lib.

  • How to convert DateTime string into a Format string

    - by AMissico
    With .NET, I have "Thursday, April 10, 2008 1:30:00 PM" and I want "dddd, dd MMMM, yyyy h:m:s t", "6:09:01 PM" and want ""hh:mm:ss tt", "Fri 29 Aug" and want "ddd d MMM", and so on. It seems I should be able to use DateTimeFormatInfo in some way. I figured I can format the date with each pattern returned by GetAllDateTimePatterns, and when the original date string and the formated date string match then I have the format. Yet, I want to generate custom formats, not the standard formats. I want the format string. I do not want the date. I have both the DateTime value and the formatted string value for the date. I need <formatString> as in ToString(<formatString>).

  • Routing classic asp and through an MVC application

    - by Matthias
    We are starting to convert a large classic asp application into MVC (using C#). An additional requirement is, that all classic routes get "translated" to MVC ones ('mydomain.com/productdetail.asp?id=13' should become 'mydomain.com/products/13') even before we start writing the first controller or view. So basically, we want to use the routing from MVC but have the classic asp handle the response. An these are my questions: How to use the new nice urls but have the classic asp handle the construction of the html result? Within the classic asp page, the new MVC url pattern should be used for links. What is the best way of translating the old urls to the new ones and make the accessible within the classic asp site (using COM I guess). When an old/classic url is requested, how would I correctly handle that request so that browsers/searchengines would understand that the page has moved to the new url? Thanks in advance!

  • Js/Jquery bind Datatable or Datalist

    - by Robin Rieger
    Scenario I have a input box for post codes. When you put in a postcode it makes a call to a web service and gets all the suburb names back and binds them to a list, like an input dropdown list. This works when I return a List<string> from the web service for just the names. No problem. The problem arises when I go to save the values to the db. When it gets saved I cannot save the name of the suburb in the suburb column in the db. I have to save the id of that suburb for the foreign key constraint. So then I changed the List<> thing slighty and cheated and returned the following. <ArrayOfString> <string>8213</string> <string>BROOKFIELD</string> <string>8214</string> <string>CHAPEL HILL</string> <string>8215</string> <string>FIG TREE POCKET</string> etc.... The reason for this is so I can have the value of the item in the drop down as the id and hence can save that in the code behind on save. To do this, I did the following: $(result).each(function (index, value) { var suburbname; var pattern = new RegExp('[0-9*]'); var m = pattern.exec(value); if (m == null) { suburbname = value var o = new Option(suburbname, suburbid); /// jquerify the DOM object 'o' so we can use the html method $(o).html(suburbname); $(document.getElementById('<%= suburb.ClientID %>')).append($("<option></option>") .attr("value", suburbid) .text(suburbname)); } else { suburbid = value } That works as well... the drop down only has name and the value for those is the number The problem....? I am making assumptions above which I don't like... I.e. that the name never has a number it, that the web service will always return the id first to set the id before running the add to the dropdown for the first time. It just feels wrong.... :S (thoughts?) So, if I change the web service to return a datatable, to out the following (which is what the whole query returns): <Suburbs diffgr:id="Suburbs1" msdata:rowOrder="0"> <SuburbID>8213</SuburbID> <SuburbName>BROOKFIELD</SuburbName> <StateID>4</StateID> <StateCode>07</StateCode> <CountryCode>61</CountryCode> <TimeZones>10.00</TimeZones> <Postcode>4069</Postcode> </Suburbs> Is there a way of acheiving the same as above in js/jquery. So when the user inputs the postcode the webservice returns the datatable and then binds it to the select with the SuburbID going into the value and the name going into the text??? Any other ways I could return the data from the web service to solve this? Note: essentially I need the option to look like this: <option value="8213">BROOKFIELD</option> I also thought I could make a second call to get just the id on the bind of the text... but I kind of want to only make one call.... Thanks in adance, Cheers Robin .net, C#, js, jquery, web service..... Solution with guidance from Billy The adding to the select using the other method below did not work, but my original way did once I had the correct variables so just used that.... The service returns: <ArrayOfMyClass> <MyClass> <ID>8213</ID> <Name>BROOKFIELD</Name> </MyClass> ... etc The js is: (note: it is onchange of the postcode input box. it runs a web service and then on success runs the following) function OnCompleted(result) { var _suburbs = result; var i = 0; $(_suburbs).each(function () { var SuburbName = _suburbs[i].Name; var SuburbID = _suburbs[i].ID; $(document.getElementById('<%= suburb.ClientID %>')).append($("<option></option>") .attr("value", SuburbID) .text(SuburbName)); i = i + 1; });

  • ASP.NET: How to initialize when *user control* is initially loaded

    - by kendor
    I have an ASP.NET user control that I'm embedding in another user control. This works fine. I need to know the best logic/method for detecting when the control is loaded. In other words, I have some display initialization logic that needs to run when the control is initially displayed. Surely there is a pattern for this. The typical method is to put (!IsPostBack) logic in the Page_Load method of the control. This works great until you end up with a state when the Parent page has already posted back many times. My user control gets added to the page but its display does not intialize properly. I'm hoping to find a way that keeps this logic inside the control, versus various hacking around in the codebehind of the parent page.

  • ODBC Connection Pooling

    - by beansy
    I have inherited a suite of .Net c# applications from a developer which talk to an Informix database on a unix server. Instead of using the usual practices for managing the database connections (disposable pattern / "open late / close early"), the code seems to open one ODBC connection when each app loads and doesn't close it. Connection pooling is turned via the ODBC administrator. Is there any way of seeing how many ODBC connections are open? What is the effect of turning off connection pooling? Am I right in thinking the .NET framework will use connection pooling anyway?

  • To Wrap or Not to Wrap: Wrapping Data Access in a Service Facade

    - by PureCognition
    For a while now, my team and I have been wrapping our data access layer in a web service facade (using WCF) and calling it from the business logic layer. Meanwhile, we could simply use the repository pattern where the business logic layer consumes the data access layer locally through an interface, and at any point in time, we can switch things out for it to hit a service instead (if necessary). The question is: When is it a good time to wrap the data access layer in a service facade and when isn't it? Right now, it seems like the main advantage is that other applications can consume the service, but if they are internal applications written in .NET then they can just consume the .NET assembly instead. Are there other advantages of having the DAL be wrapped in a service that I am unaware of?

  • Regexing it up with IIS re-write module

    - by Michael Jasper
    I am developing a profile-based web application where each user is assigned there own url through their username & iis rewrite mod's magic. A typical user's profile url would be http://www.mymark.com/mike Each user is also created a blog in a multi-user wordpress installation. The wordpress url would look like this: http://www.mymark.com/blog/mike I am trying to use the rewrite module to create more canonical urls for the user (http://www.mymark.com/mike/blog), and have tried several regex variations that I have created through RegExr(a regex generation tool) and come up with this as the pattern to match (www.|)mymark.com/([^/]+)/blog but haven't had any success so far. What am I doing wrong here? Here is a screen shot of my re-write rule:

  • Design Patterns: What's the antithesis of Front Controller?

    - by Brian Lacy
    I'm familiar with the Front Controller pattern, in which all events/requests are processed through a single centralized controller. But what would you call it when you wish to keep the various parts of an application separate at the presentation layer as well? My first thought was "Facade" but it turns out that's something entirely different. In my particular case, I'm converting an application from a sprawling procedural mess to a clean MVC architecture, but it's a long-term process -- we need to keep things separated as much as possible to facilitate a slow integration with the rest of the system. Our application is web-based, built in PHP, so for instance, we have an "index.php" and an IndexController, a "account.php" and an AccountController, a "dashboard.php" and DashboardController, and so on.

  • Controlling azure worker roles concurrency in multiple instance

    - by NER1808
    I have a simple work role in azure that does some data processing on an SQL azure database. The worker basically adds data from a 3rd party datasource to my database every 2 minutes. When I have two instances of the role, this obviously doubles up unnecessarily. I would like to have 2 instances for redundancy and the 99.95 uptime, but do not want them both processing at the same time as they will just duplicate the same job. Is there a standard pattern for this that I am missing? I know I could set flags in the database, but am hoping there is another easier or better way to manage this. Thanks

  • returning a memoryStream as a string

    - by WeNeedAnswers
    What is wrong with this statement? return new ASCIIEncoding().GetString(memoryStream.ToArray()); I know about the Dispose pattern, have checked out the underlying memoryStream and seen that there is nothing really happening in the dispose. So why shouldn't I allow one of my developers to do this. The aim is to make the code succinct and not create references that are not required, Hopefully getting the Garbage Collector to kick in soon as. Its just niggling me, I feel that the memoryStream lets the party down, when compared to what the other streams do and why they implement the IDispose. Can someone please give me a good reason not to allow the code above. I got a gut feeing about the code not being right but need some back up. :)

  • DTO and mapper generation from Domain Objects

    - by Nicolas
    I have plenty of java domain objects that I need to transform to DTOs. Please, don't start with the anti-pattern thing, the Domain Objects are what they are because of a long history, and I can't modify them (or not too much, see below). So, of course, we've passed the age of doing all that manually. I've looked around, and dozer seems the framework of choice for DTO mapping. But... what I'd really like is this: annotate classes and fields that I want in DTO, and run a tool that would generate the DTOs and the mappers. Does that sound too unreasonable? Does such a tool already exist?

  • LINQ to SQL repository - caching data

    - by creativeincode
    I have built my first MVC solution and used the repository pattern for retrieving/inserting/updating my database. I am now in the process of refactoring and I've noticed that a lot of (in fact all) the methods within my repository are hitting the database everytime. This seems overkill and what I'd ideally like is to do is 'cache' the main data object e.g. 'GetAllAdverts' from the database and to then query against this cached object for things like 'FindAdvert(id), AddAdvert(), DeleteAdvert() etc..' I'd also need to consider updating/deleting/adding records to this cache object and the database. What is the best apporoach for something like this? My knowledge of this type of things is minimal and really looking for advice/guidance/tutorial to point me in the right direction. Thanks in advance.

  • First time unit testing (in silverlight)

    - by Jakob
    Hi I've searched some other posts, but most of them assumed that people knew what they were doing in their unit testing, and frankly I don't. I see the idea behind unit testing, and I'm coding an silverlight application much in the blind right now, and I'd like to write some unit tests to kind of be sure I'm on the right path. I'd like to be able to use the SL4 vs 2010 silverlight unit test project template, to keep it simple and not use external tools. So what I need an answer for are questions like: what are the methods of unit testing? what are the differences between unit tests, and automated unit tests? How do I meaningfully unit test in silverlight? What should I be aware of while unit testing (in silverlight) ? Also should I implement some kind of IRepository pattern in my silverlight app to make unit testing easier?

  • Scala match question

    - by javier
    Hello to everyone. I came across with an error on my Scala code that I cannot solve by myself (I am new at Scala). I have the following code: def myFunction(list: List[Any]): String = { var strItems : String = ""; list.foreach(item => { strItems += item match { case x:JsonSerializable => x.toJson() case y:String => ("\"" + y + "\"") case _ => item.toString } if(item != list.last) strItems += ","; }) strItems; } The error I am getting is: error: pattern type is incompatible with expected type; found : String required: Unit case y:String = ("\"" + y + "\"") Any idea why? PS: is there a more performant way to code myFunction

  • Validate a string in a table in SQL Server

    - by Ashish Gupta
    I need to check If a column value (string) in SQL server table starts with a small letter and can only contain '_', '-', numbers and alphabets. I know I can use a SQL server CLR function for that. However, I am trying to implement that validation using a scalar UDF and could make very little here...I can use 'NOT LIKE', but I am not sure how to make sure I validate the string irrespective of the order of characters or in other words write a pattern in SQL for this. Am I better off using a SQL CLR function? Any help will be appreciated.. Thanks in advance

  • Any thoughts on A/B testing in Django based project?

    - by Maddy
    We just now started doing the A/B testing for our Django based project. Can I get some information on best practices or useful insights about this A/B testing. Ideally each new testing page will be differentiated with a single parameter(just like Gmail). mysite.com/?ui=2 should give a different page. So for every view I need to write a decorator to load different templates based on the 'ui' parameter value. And I dont want to hard code any template names in decorators. So how would urls.py url pattern will be?

  • Do any browsers yet support HTML5's checkValidity() method?

    - by James A. Rosen
    The HTML5 spec defines some very interesting validation components, including pattern (for validating against a Regexp) and required (for marking a field as required). As best I can tell, however, no browser yet actually does any validation based on these attributes. I found a comparison of HTML5 support across engines, but there is no information about validation there. In the browsers I've tried (Firefox 3.5.8 and Safari 4.0.4), no object has a checkValidity() method, so I can't run the validations even though I can define them. Is there any support for this feature out there so I can experiment?

  • .NET Database Apps: Your Preferred Setup

    - by mdvaldosta
    I'm struggling to settle into a pattern for developing typical database driven apps in C# and Visual Studio. There are so many ways to set them up, using drag/drop datasets and adapters or writing the queries manually in ADO.NET or Linq to SQL, Linq to Entities, to bind or not to data bind etc etc. Where to store the connection string, in app.config or in a method or both etc etc. So many tutorials and all of them are different. Everytime I write something I start hating the way it looks and works, so I scrap it and start over. It's getting a bit tedious. Maybe it's alittle of the OCD in me. Would any of you professional developers out there share your method of setting up and structuring your database logic and maybe some sample code? It's really how to go about organizing the code and the method(s) of interacting with SQL that I'm trying to get into a routine with, one that works and won't get me laughed at by someone reviewing it.

  • Creating an SQL Compact file: Template or script?

    - by David Veeneman
    I am writing an application that writes to SQL Compact files that have a specific schema, and I am now implementing the New File use case. The simplest approach seems to be to use a Template pattern: first, create a template file that lives in the application directory. Then, when the user selects New File, the template is copied to the name and destination specified by the user in a New File dialog. The alternative is a scripted approach: Use the same New File dialog, but dispense with the template file. Instead, create an empty SQL Compact file using the name/destination specified by the user, and then execute a T-SQL script on it from managed code. At this point, I am leaning toward the Template approach, because it is simpler. Is there any reason I should not use that approach? Thanks for your help.

  • Another Java vs. Scala perspective - is this typical?

    - by Alex R
    I have been reading about Scala for a while and even wrote some small programs to better understand some of the more exoteric features. Today I decided to do my first "real project", translating some 60 lines of ugly Java code to Scala to rewrite it using the better pattern-matching features (why? because the Java version was becoming hard to maintain due to excessive combination of regex and conditionals). About halfway through the editing process, Eclipse thew up this error: I get the general impression that the Scala IDE in Eclipse is a lot buggier and less complete than its Java equivalent. Is this correct or do I just have a bad installation? Is there a better IDE for Scala?

  • How do you sort files numerically?

    - by Zachary Young
    Hello all, First off, I'm posting this because when I was looking for a solution to the problem below, I could not find one on stackoverflow. So, I'm hoping to add a little bit to the knowledge base here. I need to process some files in a directory and need the files to be sorted numerically. I found some examples on sorting--specifically with using the lamba pattern--at wiki.python.org, and I put this together: #!env/python import re tiffFiles = """ayurveda_1.tif ayurveda_11.tif ayurveda_13.tif ayurveda_2.tif ayurveda_20.tif ayurveda_22.tif""".split('\n') numPattern = re.compile('_(\d{1,2})\.', re.IGNORECASE) tiffFiles.sort(cmp, key=lambda tFile: int(numPattern.search(tFile).group(1))) print tiffFiles I'm still rather new to Python and would like to ask the community if there are any improvements that can be made to this: shortening the code up (removing lambda), performance, style/readability? Thank you, Zachary
