  • ASP.NET MVC, Cache individual User Control

    - by Alex
    How do I cache an individual user control with ASP.NET MVC? I also need the VaryByParam etc support that usually comes with ASPX Output Caching. I don't want to cache the entire action though, only one of my user controls in the view. An example would be nice :) Thank you!

  • Validating primitive types in ASP.NET MVC

    - by Alex
    I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

  • SkinId and Dynamic Control

    - by Alex
    Hi! I have some control that I add dynamically to my page: public partial class _Default : Page { protected override void CreateChildControls() { base.CreateChildControls(); var testControl = new TestControl { SkinID = "TestSkin" }; Controls.Add(testControl); } } I have the following skin file for this control: <cc:TestControl runat="server" SkinID="TestSkin" TestProperty="LALALA" /> But TestProperty is null (if control is static all works): public class TestControl : LinkButton { public string TestProperty { get; set; } protected override void OnPreRender(EventArgs e) { if (String.IsNullOrEmpty(TestProperty)) { throw new ArgumentNullException("TestProperty"); } } } Any ideas about how to fix it?

  • JSF - Random Number using Beans (JAVA)

    - by Alex Encore Tr
    I am trying to create a jsf application which, upon page refresh increments the hit counter and generates two random numbers. What should be displayed on the window may look something like this: On your On your roll x you have thrown x and x For this program I decided to create two Beans, one to hold the page refresh counter and one to generate a random number. Those look like this for the moment: CounterBean.java package diceroll; public class CounterBean { int count=0; public CounterBean() { } public void setCount(int count) { this.count=count; } public int getCount() { count++; return count; } } RandomNumberBean.java package diceroll; import java.util.Random; public class RandomNumberBean { int rand=0; Random r = new Random(); public RandomNumberBean() { rand = r.nextInt(6); } public void setNextInt(int rand) { this.rand=rand; } public int getNextInt() { return rand; } } I have then created an index.jsp to display the above message. <html> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <f:view> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Roll the Dice</title> </head> <body> <h:form> <p> On your roll # <h:outputText value="#{CounterBean.count} " /> you have thrown <h:outputText value="#{RandomNumberBean.rand}" />and <h:outputText value="#{RandomNumberBean.rand} " /> </p> </h:form> </body> </f:view> </html> However, when I run the application, I get the following message: org.apache.jasper.el.JspPropertyNotFoundException: /index.jsp(14,20) '#{RandomNumberBean.rand}' Property 'rand' not found on type diceroll.RandomNumberBean Caused by: org.apache.jasper.el.JspPropertyNotFoundException - /index.jsp(14,20) '#{RandomNumberBean.rand}' Property 'rand' not found on type diceroll.RandomNumberBean I suppose there's a mistake with my faces-config.xml file, so I will post this here as well, see if somebody can provide some help: faces-config.xml <?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd" version="2.0"> <managed-bean> <managed-bean-name>CounterBean</managed-bean-name> <managed-bean-class>diceroll.CounterBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> <managed-bean> <managed-bean-name>RandomNumberBean</managed-bean-name> <managed-bean-class>diceroll.RandomNumberBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> </faces-config>

  • Is there a way to transfer windows license to a different machine?

    - by Alex Khvatov
    I purchased a license and used Windows 7 Home Premium 32 bit OS for a while. But recently I bought a 64 bit version to take advantage of the larger RAM the machine had and hence reinstalled the OS and activated a new license for the 64-bit version. Now, I am in a need to install the 32 bit version on another machine. How do I go about reactivating a license on another machine? (again the license currently is not used) Am I going to have issues with Microsoft not letting me reactivate that license on a different machine? Thank you.

  • Making alarm clock with NSTimer

    - by Alex G
    I just went through trying to make an alarm clock app with local notifications but that didn't do the trick because I needed an alert to appear instead of it going into notification centre in iOS 5+ So far I've been struggling greatly with nstimer and its functions so I was wondering if anyone could help out. I want when the user selects a time (through UIDatePicker, only time) for an alert to be displayed at exactly this time. I have figured out how to get the time from UIDatePicker but I do not know how to properly set the firing function of nstimer. This is what I have attempted so far, if anyone could help... be much appreciated. Thank you Example (it keeps going into the function every second opposed to a certain time I told it too... not what I want): NSDate *timestamp; NSDateComponents *comps = [[[NSDateComponents alloc] init] autorelease]; [comps setHour:2]; [comps setMinute:8]; timestamp = [[NSCalendar currentCalendar] dateFromComponents:comps]; NSTimer *f = [[NSTimer alloc] initWithFireDate:timestamp interval:0 target:self selector:@selector(test) userInfo:nil repeats:YES]; NSRunLoop *runner = [NSRunLoop currentRunLoop]; [runner addTimer:f forMode: NSDefaultRunLoopMode];

  • Filtering spectrum using FIR filters

    - by Alex Hoppus
    If i have signal values x[T] and filter coefficients b[i], i can perform filtering using convolution. Suppose i have spectrum of x (after FFT) and i need to perform filtering using filters coefficients, how can i perform this? I heard that in frequency domain it will be multiplying, rather than convolution (time domain). But i can't find an equation to use it. I have 614000 values in y = fft(x[T]) vector and 119 filter coefficients (generated using fdatool), i can't multiply them directly ... Thanks.

Also is there a way I can send the tags to a "class" attribute instead of "name". It seems to not work in Safari.

  • MySQL select one field from table WHERE condition is in multiple rows

    - by Alex
    Tried to find the answer, but still couldn't.. The table is as follows: id, keyword, value 1 display 15.6 1 harddrive 320 1 ram 3 So what i need is something like this.. Select an id from this table where (keyword="display" and value="15.6") AND (keyword="harddrive" and value="320") There's also a possibility that there will be 3 or 4 such keyword conditions which should result into returning one id (one row) It seems there's something to deal with UNION but i didn't use it before so i can't figure it out Thanks in advance

  • What are the exact versions of stuff you had to install in order to be able to step-debug a Scala pr

    - by Alex R
    How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence the second part of my question, which is really the most important part: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

  • Running an application from an USB device...

    - by Workshop Alex
    I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

  • Multiple calls to /dev/stdin using python subprocess (*nix)

    - by Alex Leach
    Hi, I have a python subprocess call which I would like to link up to three pipes (two standard in and one standard out). I know that there is only one /dev/stdin, but there's all those other devices in /dev I don't know about, and don't know of any python os, sys or subprocess modules that will utilise them in a manner which allows me to give the device path to subprocess.Popen. The reason I ask is because I would like to pipe information from a mysql database or tar archive rather than a directory structure I currently have which has 28,000 directories in. The directory names alone uses a LOT of space! The alternative is to tar / gunzip the entire directory structure and manoeuvre through the compressed archive. With either solution, mysql or tar, I would still like to have two pipes into subprocess.Popen and one out, so that I can bypass the HDD. Any need for an example??

  • How to read in the XML file on a remote website using JSP?

    - by Alex
    Hi, I'm using java servlets and jsp in my application and I need to read the remote XML file and properly render it into HTML and display on a web page...What is the technology used for reading process?Should I use HTTPURLConnection class to read the contents of the xml file or there is some other way? And also,if I use servlet as a controller and JSP as a view,what would be the responsibility of servlet and jsp in this process?Should servlet just read the whole XML file and then just pass the read output to JSP which will just print it and render properly using XSL for example? I really hope to hear from any people who may help, With kind regards

  • Problem with using the XPATH functions

    - by Alex
    I've got a problem with using the XPATH functions. When I try to call some functions like lower-case or upper-case etc,they are not executed and I can't figure the problem out. I included the namespace xmlns:fn="http://www.w3.org/2005/xpath-functions" at the top of my XSL stylesheet and use fn namespace to call these functions but anyway nothing is working. Can anyone explain the reason and what I should do in order to be able to use the following functions? Cheers

  • Why does Perl lose foreign characters on Windows; can this be fixed (if so, how)?

    - by Alex R
    Note below how ã changes to a. NOTE2: Before you blame this on CMD.EXE and Windows pipe weirdness, see Experiment 2 below which gets a similar problem using File::Find. The particular problem I'm trying to fix involves working with image files stored on a local drive, and manipulating the file names which may contain foreign characters. The two experiments shown below are intermediate debugging steps. The ã character is common in latin languages. e.g. http://pt.wikipedia.org/wiki/Cão Experiment 1 Experiment 2 To get around my particular problem, I tried using File::Find instead of piped input. The issue actually gets worse: Debugging update: I tried some of the tricks listed at http://perldoc.perl.org/perlunicode.html, e.g. use utf8, use feature 'unicode_strings', etc, to no avail.
