• Store Business Rules in XML Document, Validate afterwards in Java, how?

  - by JavaPete

  Example XML Rules document: <user> <username> <not-null/> <capitals value="false"/> <max-length value="15"/> </username> <email> <not-null/> <isEmail/> <max-length value="40"/> </email> </user> How do I implement this? I'm starting from scratch, what I currently have is a User-class, and a UserController which saves the User object in de DB (through a Service-layer and Dao-layer), basic Spring MVC. I can't use Spring MVC Validation however in our Model-classes, I have to use an XML document so an Admin can change the rules I think I need a pattern which dynamically builds an algorithm based on what is provided by the XML Rules document, but I can't seem to think of anything other than a massive amount of if-statements. I also have nothing for the parsing yet and I'm not sure how I'm gonna (de)couple it from the actual implementation of the validation-process.

• Odd Things of ASP.NET MVC Deployment on IIS 6

  - by misaxi

  Recently, I am a bit interested in the deployment of ASP.NET MVC application on IIS6 because Phil Haack posted an easier way to deploy ASP.NET MVC application on ASP.NET 4. So I decided to see how different version of ASP.NET MVC works on different version of ASP.NET. First off, I created an ASP.NET MVC 2 project in Visual Studio 2010 and deploy it to IIS 6 on Windows Server 2003 (only .NET framework 3.5 installed). I set the application to run in ASP.NET 2.0 and no extra stuff. Because I just wanted to see what sort of error would occur. And as expected, some error was reported as following. Then, I set the Copy Local attribute of System.Web.Mvc assembly to true as following and deploy again. As a result, the application ran smoothly. I had read tons of materials talked about the mess of deploying MVC application on IIS 6. And I did fight to tackle the deploying issues in my previous project. At least, if had used Extensionless Url in your application, you should have configured wildcard mapping in IIS. But in this case, I even didn’t have chance to do so. What the heck was going on exactly? Did I discover a new continent?

• How to set up WebLogic 10.3.3. security for JAX_WS web services?

  - by Roman Kagan

  I have quite simple task to accomplish - I have to set up the security for web services ( basic authentication with hardcoded in WLES user id and password). I set the web.xml (see code fragment below) but I have tough time configuring WebLogic. I added IdentityAssertionAuthenticator Authentication Provider, set it as Required, modified DefaultAuthenticator as Optional and I went to deployed application's security and set the role to "thisIsUser" and at some point it worked, but not anymore (I redeployed war file and set web service security the same way but no avail.) I'd greatly appreciate for all your help. <security-constraint> <display-name>SecurityConstraint</display-name> <web-resource-collection> <web-resource-name>ABC</web-resource-name> <url-pattern>/ABC</url-pattern> </web-resource-collection> <auth-constraint> <role-name>thisIsUser</role-name> </auth-constraint> </security-constraint>

• Javascript get image height works in all browsers but firefox...please help?

  - by Calvin

  So I am fairly new to Javascript (a lot of experience in PHP), but I have this basic script that checks a link that redirects to a URL to see what the image height is. If it is a certain height then it adds one to a variable, otherwise nothing. I would easily do this in PHP but the images are on other servers and not my own so it doesn't work. Anyways, ehre is the script. Let me know if you have any tips. Works well and tested in Chrome, Safari, Opera, and IE. <script language='JavaScript'> window.onload = function() { var nstar = 0, urls = []; urls[0] = "http://optout.imiclk.com/cgi/nai_status.cgi?nocache="; urls[1] = "http://www.adbrite.com/mb/nai_optout_check.php?nocache="; urls[2] = "http://events.adchemy.com/visitor/auuid/nai-status?nocache="; function getImgSize(imgSrc){ var newImg = new Image(); newImg.src = imgSrc; return{height:newImg.height, width:newImg.width} } for(i=0,length=urls.length;i<length;i++){ if(getImgSize(urls[i]).height==43){nstar++;} } document.getElementById('tracknum').innerHTML = "<b>" + nstar + "</b>"; } </script>

• C# Linq Select Problem in Method Chain.

  - by Gnought

  Note that the _src inherit IQueryable<U> and V inherit new(); I wrote the following statement, there is no syntax error. IQueryable<V> a = from s in _src where (s.Right - 1 == s.Left) select new V(); But if i re-wrote it as follows, the Visual Studio editor complains an error in the "Select" IQueryable<V> d = _src.Where(s => s.Right - 1 == s.Left).Select(s=> new V()); The Error is: The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly. Candidates are: System.Collections.Generic.IEnumerable<V> Select<U,V>(this System.Collections.Generic.IEnumerable<U>, System.Func<U,V>) (in class Enumerable) System.Linq.IQueryable<V> Select<U,V>(this System.Linq.IQueryable<U>, System.Linq.Expressions.Expression<System.Func<U,V>>) (in class Queryable) Could anyone explain this phenomenon, and what the solution is to fix the error?

• displaying a WPF Window from a System.Configuration.Install.Installer class

  - by cbeuker

  Greetings all, I have a question. I have created a WPF application. So, I naturally created an installer (Visual Studio Install project) for it. In the Commit section of the installer I want to launch a WPF window which is my configuration wizard. So I created a Installer class, overrode the Commit method and put the following in method: Application theApp = new Application; theApp.Run (new MyWPFWizardWindow()); I keep getting the error: The calling thread must be STA, because many UI components require this. No problems, this makes as it is a GUI application. But I can't, for the life of me, get the installer to fire up my window. I have tried putting [STAThread] on the method. I have tried firing up a thread and setting the ApartmentState to STA. I am guessing it's something really simple that I am over looking. Anyone have any thoughts? Thanks in advance.. cmb..

• JavaScript: Changing src-attribute of a embed-tag

  - by Mike

  I have the following scenario. I show the user some audio files from the server. The user clicks on one, then onFileSelected is eventually executed with both the selected folder and file. What the function does is change the source from the embedded object. So in a way, it is a preview of the selected file before accepting it and save the user's choice. A visual aid. HTML <embed src="/resources/audio/_webbook_0001/embed_test.mp3" type="audio/mpeg" id="audio_file"> JavaScript function onFileSelected(file, directory) { jQuery('embed#audio_file').attr('src', '/resources/audio/'+directory+'/'+file); }; Now, this works fine in Firefox, but Safari and Chrome simply refuse to change the source, regardless of Operating System. jQuery finds the object (jQuery.size() returns 1), it executes the code, but no change in the HTML Code. Why does Safari prevent me from changing the <embed> source and how can I circumvent this?

• MSBuild - How to build a .NET solution file (in an XML task script) from pre-written command line commands

  - by Devtron

  Hello. I have been studying MSBuild as I have the need to automate my development shop's builds. I was able to easily write a .BAT file that invokes the VS command prompt and passes my MSBuild commands to it. This works rather well and is kinda nifty. Here is the contents of my .BAT build file: call "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat" cd C:\Sandbox\Solution msbuild MyTopSecretApplication.sln /p:OutputPath=c:\TESTMSBUILDOUTPUT /p:Configuration=Release,Platform=x86 pause ^ This works well but I now have the need to use the MSBuild task for TeamCity CI. I have tried to write a few MSBuild scripts but I cannot get them to work the same. What is the equivalent build script to the command I am using in my .BAT file? Any ideas? I have tried using something like this, but no success (I know this is wrong): <?xml version="1.0"?> <project name="Hello Build World" default="run" basedir="."> <target name="build"> <mkdir dir="mybin" /> <echo>Made mybin directory!</echo> <csc target="exe" output="c:\TESTMSBUILDOUTPUT"> <sources> <include name="MyTopSecretApplication.sln"/> </sources> </csc> <echo>MyTopSecretApplication.exe was built!</echo> </target> <target name="clean"> <delete dir="mybin" failonerror="false"/> </target> <target name="run" depends="build"> <exec program="mybin\MyTopSecretApplication.exe"/> </target> What I simply need is an MSBuild XML build script that compiles a single solution for Release mode to a specified output directory. Any help?

• .net web service annoying issue

  - by JL

  Excuse the title, but it's best I just explain the problem. I have 2 projects in my solution A Class Library A Web Application, which consists of a web service (asmx). the web service has code sitting in the app_code folder, with a file [webservicename].cs Inside the webservice code behind class, I have a web method here is a sample example (its simplified): [WebMethod] public EnumTaskExportState ProcessTask() { var tm = new UploadTaskManager(); return tm.ProcessTask(); } Now at design time, in visual studio (2010 or 2008), when I right click on UploadTaskMananger, and then select "Go to definition". I get taken to AppData\Temp[some folder structure]...etc.... and it displays the public class definition. Instead I would like to have complete integration, so that I get taken directly to the actual class in the class library project. My guess is, this is happening because I am using the app_code route, and not a compiled file for the web service class. But I don't know any other way to do this. How can I fix this? Possibly do away with the need for the app_code directory?

• How do I change the application background color at run-time in a Flex 3.5 application?

  - by Adam Tuttle

  I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

• How do I parse data received in a memorystream?

  - by Kerberos42

  I'm new to using sockets. I have a very basic client that sends a request, and waits for a response. The response is one stream, but has two parts. The first part is prefixed with ANS and is a set of key/value pairs in this form: KEY:Value with each pair on a separate line. The second part of the response is prefixed by RCT and this is pre-formatted text that needs to be send directly to a printer. So what would be the best way to extract both parts of the response, and in the first part, get each Key:Value pair. I might not even need them all, but I have to look at each one to see what the values are then decide what to do with it. I'm currently writing the response out to a textbox just to understand what its doing, but now I need to actually do something with the data. Here's a data sample, as it is received: ANS Result: Data Received RCPRES:Q[81] TML:123 OPP: MRR:000000999999 <several dozen more KEY:Value pairs> RCTNov 05 2013 04:03 pm Trans# 123456 <pre-formatted text>

• Add two hexBinarys with XPATH 1.0

  - by fielding

  Hi, my xml document looks somewhat like that (Values are both xsl:hexBinary): <Offsets> <Offset> <Name>ErrorOffset</Name> <Value>DD</Value> </Offset> <Offset> <Name>OtherOffset</Name> <Value>FF</Value> </Offset> </Offsets> <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>02</Code> <Offset>ErrorOffset</Offset> </Value> now i want to transform this to a new xml file: <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>DF</Code> </Value> All that should happen is adding <Offset> to the basic <Value>. But plain + returns NaN and sum() expects only one parameter. XSLT and XPATH are quite nice, but it goes on my nerves that easy operations like adding two hex values just dont work as easy as it should.

• URL path changes between dev and published version

  - by Bob Horn

  I just got Scott Hanselman's chat app with SignalR working with ASP.NET MVC 4. After hours of configuration, trial and error, and getting different versions of Windows to talk to each other on my home network, it's all working except that I'm left with one issue that I'm not sure how to handle. This line of javascript has to change, depending on if I'm running the app through Visual Studio or the published (IIS) version: Works when running within VS: var connection = $.connection('echo'); Works with published version: var connection = $.connection('ChatWithSignalR/echo'); When I run within VS, the URL is: http://localhost:9145/ And the published version is: http://localhost/ChatWithSignalR If I don't change that line of code, and try to run the app within VS, using the javascript that has ChatWithSignalR in it, I get an error like this: Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:9145/ChatWithSignalR/echo/negotiate?_=1347809290826 What can I do so that I can use the same javascript code and have it work in both scenarios? var connection = $.connection('??????'); Note, this is in my Global.asax.cs: RouteTable.Routes.MapConnection<MyConnection>("echo", "echo/{*operation}");

• XSL(like) declarative language as MVC view over strongtyped model?

  - by Martin Kool

  As a huge XSL fan, I am very happy to use xsl as the view in our proprietary MVC framework on ASP.NET. Objects in the model are serialized under the hood using .NET's xml serializer, and we use quite atomic xsl templates to declare how each object or property should transform. For example: <xsl:template match="/Article"> <html> <body> <div class="article"> <xsl:apply-templates /> </div> </body> </html> </xsl:template> <xsl:template match="Article/Title"> <h1> <xsl:apply-templates /> </h1> </xsl:template> <xsl:template match="@*|text()"> <xsl:copy /> </xsl:template> This mechanism allows us to quickly override default matching templates, like having a template matching on the last item in a list, or the selected one, etc. Also, xsl extension objects in .NET allow us just the bit of extra grip that we need. Common shared templates can be split up and included. However Even though I can ignore the verbosity downside of xsl (because Visual Studio schema intellisense + snippets really is slick, praise to the VS-team), the downside of not having intellisense over strongtyped objects in the model is really something that's bugging me. I've seen ASP.NET MVC + user controls in action and really starting to love it, but I wonder; Is there a way of getting some sort of intellisense over XML that we're iterating over, or do you know of a language that offers the freedom and declarativeness of XSL but has the strongtype/intellisense benefits of say webforms/usercontrols/asp.net.mvc-view? (I probably know the answer: "no", and I'll find myself using Phil Haack's utterly cool mvc shizzle soon...)

• Write out to text file using T-SQL

  - by sasfrog

  I am creating a basic data transfer task using TSQL where I am retrieving certain records from one database that are more recent than a given datetime value, and loading them into another database. This will happen periodically throughout the day. It's such a small task that SSIS seems like overkill - I want to just use a scheduled task which runs a .sql file. Where I need guidance is that I need to persist the datetime from the last run of this task, then use this to filter the records next time the task runs. My initial thought is to just store the datetime in a text file, and update (overwrite) it as part of the task each time it runs. I can read the file in without problems using T-SQL, but writing back out has got me stuck. I've seen plenty of examples which make use of a dynamically-built bcp command, which is then executed using xp_cmdshell. Trouble is, security on the server I'm deploying to precludes the use of xp_cmdshell. So, my question is, are there other ways to simply write a datetime value to a file using TSQL, or should I be thinking about a different approach? EDIT: happy to be corrected about SSIS being "overkill"...

• Program always returns binary '>>' : no operator found which takes a left-hand operand of type error

  - by Tom Ward

  So I've been set a task to create a temperature converter in C++ using this equation: Celsius = (5/9)*(Fahrenheit – 32) and so far I've come up with this (I've cut out the 10 lines worth of comments from the start so the code posted begins on line 11, if that makes any sense) #include <iostream> #include <string> #include <iomanip> #include <cmath> using namespace std; int main () { float celsius; float farenheit; std::cout << "**************************" << endl; std::cout << "*4001COMP-Lab5-Question 1*" << endl; std::cout << "**************************" << endl << endl; std::cout << "Please enter a temperature in farenheit: "; std::cin >> farenheit >> endl; std::cout << "Temperature (farenheit): " << endl; std::cout << "Temperature (celsius): " << celsius << endl; std::cin.get(); return 0; } Everytime I try to run this program I get a heap of errors with this one appearing every time: 1m:\visual studio 2010\projects\week 5\week 5\main.cpp(26): error C2678: binary '' : no operator found which takes a left-hand operand of type 'std::basic_istream<_Elem,_Traits' (or there is no acceptable conversion) I've tried everything I can think of to get rid of this error but it reappears every time, any idea on how to fix this?

I have create an instance. scaner Comp = new scaner(listBox2, listBox1, listBox3, listBox4, listBox5); In scaner.cs file I use it like this. class scaner { public ListBox ls; public ListBox lsE; public ListBox lsIVars; public ListBox lsNumbers; public ListBox lsStrings; public scaner(ListBox ls, ListBox lsE, ListBox lsIVars, ListBox lsNumbers, ListBox lsStrings) { this.ls = ls; this.lsE = lsE; this.lsIVars = lsIVars; this.lsNumbers = lsNumbers; this.lsStrings = lsStrings; } } My question : How can i replaced this big code to more "comfortably" method. scaner Comp = new scaner(listBox2, listBox1, listBox3, listBox4, listBox5); IF i had more then 5 listbox's ,it will be awful. How can i acced form another class file "Listbox's" Thanks for answers.

• What is common between environments within a shell terminal session?

  - by Matt1776

  I have a custom shell script that runs each time a user logs in or identity is assumed, its been placed in /etc/profile.d and performs some basic env variable operations. Recently I added some code so that if screen is running it will reattach it without needing me to type anything. There are some problems however. If I log-in as root, and su - to another user, the code runs a second time. Is there a variable I can set when the code runs the first time that will prevent a second run of the code? I thought to write something to the disk but then I dont want to prevent the code from running if I begin a new terminal session. Here is the code in question. It first attempts to reattach - if unsuccessful because its already attached (as it might be on an interruped session) it will 'take' the session back. screen -r if [ -z "$STY" ]; then exec screen -dR fi Ultimately this bug prevents me from substituting user to another user because as soon as I do so, it grabs the screen session and puts me right back where I started. Pretty frustrating

• C++ universal data type

  - by Gokul

  I have a universal data type, which is passed by value, but does not maintain the type information. We store only pointers and basic data types(like int, float etc) inside this. Now for the first time, we need to store std::string inside this. So we decided to convert it into std::string* and store it. Then comes the problem of destruction. We don't like to copy the std::string every time. So i am thinking of an approach like this. Say the data type looks like this class Atom { public : enum flags { IS_STRING, IS_EMPTY, HAS_GOT_COPIED, MARKER }; private: void* m_value; std::bitset<MARKER> m_flags; public: ..... Atom( Atom& atm ) { atm.m_flags.set( HAS_GOT_COPIED ); ..... } ..... ~Atom() { if( m_flags.test(IS_STRING) && !m_flags.test(HAS_GOT_COPIED) ) { std::string* val = static_cast<std::string*>(m_value); delete val; } } }; Is this a good approach to find out whether there is no more reference to std::string*? Any comments.. Thanks, Gokul.

• What are various methods for discovering test cases

  - by NativeByte

  All, I am a developer but like to know more about testing process and methods. I believe this helps me write more solid code as it improves the cases I can test using my unit tests before delivering product to the test team. I have recently started looking at Test Driven Development and Exploratory testing approach to software projects. Now it's easier for me to find test cases for the code that I have written. But I am curios to know how to discover test cases when I am not the developer for the functionality under test. Say for e.g. let's have a basic user registration form that we see on various websites. Assuming the person testing it is not the developer of the form, how should one go about testing the input fields on the form, what would be your strategy? How would you discover test cases? I believe this kind of testing benefits from exploratory testing approach, i may be wrong here though. I would appreciate your views on this. Thanks, Byte

• How to write a generic USB Host Driver for Printers from various vendors?

  - by Ullas

  I want to develop a USB host on an embedded device that will talk to printers from various vendors. Drivers for the vendor specific printers would be available on PC which is ultimately communicating with printer but my device is facilitating this communication and needs to perform the basic handshaking/setup of the printer (i.e, it needs to know when the printer is connected, what are the socket IDs that needs to be opened for CTRL and DATA transmissions etc). All of these printers are supposed to comply with IEEE 1284.4 standards but I see that many of them vary quiet a bit. One approach I have is to take the USB traces of handshaking from each of these printers and write various sections of code respectively (I know, that sounds ridiculous!). Is there a generic way to do this? Is there any available forum where these standard informations are mentioned? For eg: EPSON uses 'EPSON-CTRL' and 'EPSON-DATA' for its control and data services which needs to be provided to get the socket ID for these services. I am pretty sure HPs, Canon's etc would have their own service names as well. As per the standards, this was supposed to be captured in IANA but I dont see anything there. Any help on this would be greatly appreciated. Thanks and regards, Ullas

• Why isn't obliterate an essential feature of Subversion?

  - by Dimitri C.

  For some years now, I'm waiting for Subversion to feature a "delete permanently" (obliterate) function. I hesitate to make the transition to Subversion (coming from Visual SourceSafe :p), because I think this is an essential feature, as otherwise I'd expect the repository to grow unstopably. However, for one reason or the other, the feature gets postponed over and over again. So I begin wondering if there is some other feature or workaround which makes the obliterate function dispensable. What do you do when you want to shrink the SVN central repository? Example 1: I check in a large third party library, and after a few weeks I realize it is not suited for my needs. I don't want that to store and backup that large amount of data forever. Example 2: I have 10 versions of 10 big third party libraries in the repository, but I only use the latest versions. Example 3: I accidentally checked in sensitive information (as suggested by John). Example 4: I accidentally checked in some big files that were never meant to be put in the repository.

• Is it a wise decision to go from dev to third line/Tier 3 dev support?

  - by dotnetdev

  Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

• PC to Macbook Pro Transition - Getting (re)started?

  - by Torus Linvald

  I'm in my second computer science course right now. I've enjoyed programming so far, but really have just scraped my way by. I've not done much programming outside of required class work. For similar reasons, I never really invested in downloading/learning software to help me program (IDE's, editors, compilers, etc). I know it sounds tedious, but my current setup is: notepad++ for coding; Filezilla to transfer .cpp & .h files to school's aludra/unix and compiling; unix tells me where my bugs are and I go back to notepad++ to debug; repeat until done. This isn't fun - and I know it could be easier. But I put it off knowing that I was soon going to switch to a Mac. And, tomorrow, I'm switching. So... How should I set up my Macbook for the best programming experience? What IDEs and editors and debuggers and so on should I download? How will Mac programming differ from PC? I'm open to all ideas and comments, even the most basic. (Background - I'm learning/programming in C++ right now. Next semester, my classes switch to Java. I'm also going to take a class in web development, with HTML/CSS/Javascript/PHP. My new laptop will be a late 2009 Macbook Pro with Leopard, or maybe Snow Leopard. Free would be preferrable for all programs.) Thank you all.
