  • JQuery UI Sortable

    - by RussP
    Can someone please help me with this one: When using UISortables where - and how do I put "serialize" into the JQuery function? I have 4 columns class '.columm' and each wit a unique id - col1,col2,col3 & col4. I can get the drag & drop bit to work I now need to put the "final" positions into a serialized array. Here is my code: $(".column").sortable({ revert: true, scroll: true, appendTo: 'body', connectWith: '.column', delay:200, stop: function() { $(".column").each(function(){ var test = $(this).attr('id'); alert(test); // //var myArray = $(this).sortable("serialize"); }) }, revertDuration:50000, scope:'scope', opacity: 0.80, }); You will see alert test. I have done this to see if I can get the col id's into an alert and I can, but where do i put .sortable( "serialize" , [options] ) and how do I do that for the 4 columns to create 1 single serialized array? having done that how/where do you set the order when you next load the page? (OK yes, I do intent to "store" the serialized array) Help please - thanks

  • How can I split abstract testcases in JUnit?

    - by Willi Schönborn
    I have an abstract testcase "AbstractATest" for an interface "A". It has several test methods (@Test) and one abstract method: protected abstract A unit(); which provides the unit under testing. No i have multiple implementations of "A", e.g. "DefaultA", "ConcurrentA", etc. My problem: The testcase is huge (~1500 loc) and it's growing. So i wanted to split it into multiple testcases. How can organize/structure this in Junit 4 without the need to have a concrete testcase for every implementation and abstract testcase. I want e.g. "AInitializeTest", "AExectueTest" and "AStopTest". Each being abstract and containing multiple tests. But for my concrete "ConcurrentA", i only want to have one concrete testcase "ConcurrentATest". I hope my "problem" is clear. EDIT Looks like my description was not that clear. Is it possible to pass a reference to a test? I know parameterized tests, but these require static methods, which is not applicable to my setup. Subclasses of an abstract testcase decide about the parameter.

  • scala: how to rewrite this function using for comprehension

    - by opensas
    I have this piece of code with a couple of nasty nested checks... I'm pretty sure it can be rewritten with a nice for comprehension, but I'm a bit confused about how to mix the pattern matching stuff // first tries to find the token in a header: "authorization: ideas_token=xxxxx" // then tries to find the token in the querystring: "ideas_token=xxxxx" private def applicationTokenFromRequest(request: Request[AnyContent]): Option[String] = { val fromHeaders: Option[String] = request.headers.get("authorization") val tokenRegExp = """^\s*ideas_token\s*=\s*(\w+)\s*$""".r val tokenFromHeader: Option[String] = { if (fromHeaders.isDefined) { val header = fromHeaders.get if (tokenRegExp.pattern.matcher(header).matches) { val tokenRegExp(extracted) = header Some(extracted) } else { None } } else { None } } // try to find it in the queryString tokenFromHeader.orElse { request.queryString.get("ideas_token") } } any hint you can give me?

  • Pass structured data from C++ app to ASP.NET web service.

    - by Odrade
    I have Visual C++ application that needs to communicate with a ASP.NET web service. Specifically, the app needs to pass structured data (e.g. objects that contain lists of structures, etc) as a parameter to one of the service methods. The C++ application is already generating an xml document that contains this data. The document is generating using an xml library, so it should always well-formed. What is a good method for passing this data to the web service? I'm thinking about passing the document to the web service as a string parameter, then deserializing to a .NET object based on an xsd. But, I hear that passing an xml doc as a string parameter is not recommended. So, my questions: What are the pitfalls associated with sending the document as a string parameter, assuming that the document itself is always well-formed? Assuming the above is a bad idea, what are some good alternate approaches?

  • How can I apply indexer to Dictionary VALUES (C#3.0)

    - by Newbie
    I have done a program string[] arrExposureValues = stock.ExposureCollection[dt] .Values.ToArray(); for(int i=0;i<arrExposureValues .length;i++) Console.WriteLine(arrExposureValues[i]); Nothing wrong and works fine. But is it possible to do something like the below for(int i=0;i<stock.ExposureCollection[dt].Count;i++) Console.WriteLine(stock.ExposureCollection[dt].Values[i]); This is just for my sake of knowledge (Basically trying to accomplish the same in one line). Note: ExposureCollection is a dictionary object Dictionary<DateTime, Dictionary<string, string>> First of all I have the doubt if it is at all possible! I am using C#3.0. Thanks.

    IEnumerable<String> existedThings = from mdinfo in mdInfoTotal select mdinfo.ItemNo; IEnumerable<String> thingsToSave = from item in lbXReadSuccess.Items.Cast<ListItem>() select item.Value; Here are two IEnumerable. I want to check whether a value in existedThings exist in thingsToSave. O.K. I can do that with 3 line code. bool hasItemNo; foreach(string itemNo in existedThings) hasItemNo= thingsToSave.Contains(itemNo); But, It looks dirty. I just want to know if there better solution.

  • Unit testing a 'legacy' WPF Application

    - by sc_ray
    The product I have been working on has been in development for the past six years. It started as a generic data entry portal into an insanely complex part WPF/part legacy application. The system has been developed for all these years without a single Unit test in its fold. Now, the point has been raised for a comprehensive unit testing framework. I have been recruited recently to work on this product and have been tasked to get the 'Testing' in order. Since the team that worked on the product for the last six years adopted 'Agile', the project lacks any documentation of the business rules or any design documents. I have been trying to write unit tests for some of the modules. But I am not sure what to Mock, how to setup my Test fixture and eventually what to Test for, since a casual glance of the methods does not reveal its intentions. Also, it has come to my attention that the code was not developed with a particular methodology in mind. Given the situation, I was wondering if the good people of Stackoverflow could provide me with some advise on how to salvage this situation. I have heard about the book 'Working with Legacy Code' that has something to say about this general situation but I was thinking about getting some pointers from individuals who have encountered similar situations within the technology stack(C#,VB,C++,.NET 3.5,WCF,SQL Server 2005).

  • How to customize the Combobox dropdown list?

    - by lp
    I have created a Combo box using HIComboBoxCreate(). When I have a long string in the dropdown list, it goes beyond the screen and the starting of the string is not visible. I want the string to be truncated with ellipsis in such a case. I have looked into the ComboBox attributes but couldn't find any that I can use to set this. I'm ready to write some extra code to do this, but I'm not sure if it possible. Can someone please help?

  • Java constructor using generic types

    - by user37903
    I'm having a hard time wrapping my head around Java generic types. Here's a simple piece of code that in my mind should work, but I'm obviously doing something wrong. Eclipse reports this error in BreweryList.java: The method initBreweryFromObject() is undefined for the type <T> The idea is to fill a Vector with instances of objects that are a subclass of the Brewery class, so the invocation would be something like: BreweryList breweryList = new BreweryList(BrewerySubClass.class, list); BreweryList.java package com.beerme.test; import java.util.Vector; public class BreweryList<T extends Brewery> extends Vector<T> { public BreweryList(Class<T> c, Object[] j) { super(); for (int i = 0; i < j.length; i++) { T item = c.newInstance(); // initBreweryFromObject() is an instance method // of Brewery, of which <T> is a subclass (right?) c.initBreweryFromObject(); // "The method initBreweryFromObject() is undefined // for the type <T>" } } } Brewery.java package com.beerme.test; public class Brewery { public Brewery() { super(); } protected void breweryMethod() { } } BrewerySubClass.java package com.beerme.test; public class BrewerySubClass extends Brewery { public BrewerySubClass() { super(); } public void androidMethod() { } } I'm sure this is a complete-generics-noob question, but I'm stuck. Thanks for any tips!

  • How to encrypt a RSAKey using another RSAKey?

    - by Tom Brito
    I know its not the usual thing to do. But the specification I'm implementing is discribed this way, and I cannot run out. I was trying to encrypt the modulus and exponent of the private key, but the following test code raises an exception because the byte array is 1 byte larger then the maximum allowed by RSA block: import java.security.KeyPair; import java.security.KeyPairGenerator; import java.security.NoSuchAlgorithmException; import java.security.NoSuchProviderException; import java.security.interfaces.RSAPrivateKey; import java.security.interfaces.RSAPublicKey; import javax.crypto.Cipher; import org.apache.commons.lang.ArrayUtils; public class TEST { public static KeyPair generateKeyPair() throws NoSuchAlgorithmException, NoSuchProviderException { KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA", "BC"); keyPairGenerator.initialize(1024); return keyPairGenerator.generateKeyPair(); } public static void main(String[] args) throws Exception { KeyPair keyPair = generateKeyPair(); RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate(); System.out.println("Priv modulus len = " + privateKey.getModulus().bitLength()); System.out.println("Priv exponent len = " + privateKey.getPrivateExponent().bitLength()); System.out.println("Priv modulus toByteArray len = " + privateKey.getModulus().toByteArray().length); byte[] byteArray = privateKey.getModulus().toByteArray(); // the byte at index 0 have no value (in every generation it is always zero) byteArray = ArrayUtils.subarray(byteArray, 1, byteArray.length); System.out.println("byteArray size: " + byteArray.length); RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic(); Cipher cipher = Cipher.getInstance("RSA", "BC"); cipher.init(Cipher.ENCRYPT_MODE, publicKey); byte[] encryptedBytes = cipher.doFinal(byteArray); System.out.println("Success!"); } } (obs. its just a test, i would never encrypt the private key with its pair public key) The byte array is 128 bytes, the exactly maximum allowed by a RSA block, so why the exception? And how to fix it?

  • INSERT SQL in Java

  • Regex whitespace and special characters

    - by Sam R.
    I have this regular expression: [^\\s\"']+|\"([^\"]*)\"|'([^']*)' which works for splitting a string by white spaces, and anything within a quotation is not delimited. However, I notice that if I put in a string that starts with "" no matches are found. How would I correct this? For example, if I enter " test 2". I want it to match to [, test, 2] Note: using java to compile the regex, here is some code Pattern pattern = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher matcher = pattern.matcher(SomeString); while (matcher.find()){ String temp = matcher.group(); //... Do something ... } Thanks.

  • only return random number when it is unique

    - by phil
    My brain is melting today and i cannot think how to do this simple bit of code. numberList is a string of numbers seperated by commas like '2, 34, 10' etc.. when i request a random number i need to check if the string has the number, if it does i want to keep requesting a random number until the random number is definitely not in the string. i cant think what kind of loop i would do to get this to work: Random r = new Random(); public int RandomPos(int max) { int i; do { i = r.Next(max) + 1; } while (!numberList.Contains(i.ToString())); return i; }

  • Overloading on return type ???

    - by Green Hyena
    scala> val shares = Map("Apple" -> 23, "MicroSoft" -> 50, "IBM" -> 17) shares: scala.collection.immutable.Map[java.lang.String,Int] = Map(Apple -> 23, MicroSoft -> 50, IBM -> 17) scala> val shareholders = shares map {_._1} shareholders: scala.collection.immutable.Iterable[java.lang.String] = List(Apple, MicroSoft, IBM) scala> val newShares = shares map {case(k, v) => (k, 1.5 * v)} newShares: scala.collection.immutable.Map[java.lang.String,Double] = Map(Apple -> 34.5, MicroSoft -> 75.0, IBM -> 25.5) From this example it seems like the map method is overloaded on return type. Overloading on return type is not possible right? Would somebody please explain what's going on here?

  • MVC JsonResult with the [Authorize] attribute going to Logon but not displaying the view

    - by likestoski
    I am seeing odd behavior with MVC 3 methods that return a JsonResult when used with the Authorize attribute. What looks like happens is the Authorize is correctly evaluated when I am not logged in but instead of redirecting to the logon form the Json response is the logon form. Is there an addition attribute that directs the response to not return a value but instead redirect the user to the logon form, preferebly with the correct returnUrl value? What I did as a demo was to setup a new MVC3 site and added AspNetMembership to my DB using the aspnet_regsql.exe command. All that is setup and logging me in correctly. The behavior of the JsonResult doesn't seem right and I'm hoping I have just missed an attribute to make it work properly. Any help is greatly appreciated, thanks in advance. Here is the Account Controller (leaving out the Post action which is not part of this question). public class AccountController : Controller { public ActionResult LogOn() { return View(); } [Authorize] public JsonResult AuthorizedAction() { return Json("Only returns if I am authorized"); } } Here is the Html markup: <script src="@Url.Content("~/Scripts/jquery-ui-1.8.11.min.js")" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $("#btnTest").click(function () { $.ajax({ type: "POST", url: "Account/AuthorizedAction", data: {}, success: function (result) { $("#testMe").html(result); }, error: function (result) { $("#testMe").html('Something broke in the ajax request'); } }); }); }); </script> <input type="button" id="btnTest" value="Test me" /> <div id="testMe">I have initial text</div> The Result: 1) When logged in I get 'Only returns if I am authorized' in my test div 2) When not logged and I have a break point in my Logon() method I see this value Request["returnUrl"] "/Account/AuthorizedAction" The test div I have displays the logon form :) this seems like I'm just not handling this properly.

  • jQuery ajax response not operating correctly

    - by mmarceau
    Ok this is frustrating... The code below works "correctly" as far as sending the email address to the SaveEmail URL and it gets saved correctly each time I change the drop down. However it only outputs the "Successful" message once, no matter how many times I change the value in the drop down. The "data" that is returned is "Successful". I would like to show the message for a couple seconds, then fade it out. It works correctly the first time I change the drop down, after that the change happens and the value gets saved, but the "Successful" message doesn't display. jQuery code: $('#AgentEmails').change(function() { var NewAddress = $('#AgentEmails').val(); $.post('SaveEmail.aspx', { email: NewAddress }, function(data) { $('#SelectMsg').html("<b>" + data + "</b>").fadeOut(); }); }); HTML code: <select ID='AgentEmails' runat='server'> <option value="[email protected]">TEST</option> </select><span id='SelectMsg'></span> What needs to be changed in my code to make this operate correctly? Thanks for the help.

  • Postback of delimited text from javascript and parsing on server side

    - by Alt_Doru
    In my ASP.NET page, I have a Javascript object, like this: var args = new Object(); args.Data1 = document.getElementById("Data1").value; args.Data2 = document.getElementById("Data2").value; args.Data3 = document.getElementById("Data3").value; The object is populated on client side using user input data. I am passing the data to a C# method, through an Ajax request: someObj.AjaxRequest(argsData1 + "|" + argsData2 + "|" + argsData3) Finally, I need to obtain the data in my C# code: string data1 = [JS args.Data1] string data2 = [JS args.Data2] string data3 = [JS args.Data3] My question is what's the best solution for this? As i am concatenating bits of user input, I don't think it's best to use "|" as a delimiter. Also, it's not clear to me how to actually parse the data in my C# code to populate the three variables with the original data.

    I have the following function I modified based off someone elses function: function showCombinations($string, $nameString, $linkParts, $i){ $wordDivider = "/"; //the divider between the words/values if ($i >= count($linkParts)){ echo "<a href='".trim($string)."'>".trim($nameString)."</a>, "; } else { foreach ($linkParts[$i] as $currentTrait){ if ($currentTrait['name']=="urltext"){ $currentNameStringName=""; //ignore } else { $currentNameStringName=$currentTrait['name']; } if ($nameString!=""){ $currentNameString=$nameString." - ".$currentNameStringName; } else { $currentNameString=$nameString.$currentNameStringName; } showCombinations($string.$currentTrait['value'].$wordDivider, $currentNameString, $linkParts, $i + 1); } } } showCombinations('', '', $linkParts, 0); All I need to change this to do is, instead of "ECHO", I want it to build up the combination and so I can do: $result = showCombinations('', '', $linkParts, 0); echo $result; I need it this way because I have to modify that $result, not just echo it.
