  • Jquery autocomplete webservices - what am i doing wrong??

    - by dzajdol
    I created a class for JSON responses: public class PostCodeJson { public String Text { get; private set; } public String Value { get; private set; } #region Constructors /// <summary> /// Empty constructor /// </summary> public PostCodeJson() { this.Text = String.Empty; this.Value = String.Empty; } /// <summary> /// Constructor /// </summary> /// <param name="_text"></param> /// <param name="_value"></param> public PostCodeJson(String _text, String _value) { this.Text = _text; this.Value = _value; } #endregion Constructors } and function returns list of this class using in webservices method: [WebMethod] public List<PostCodeJson> GetPostCodesCompletionListJson(String prefixText, Int32 count) { return LibDataAccess.DBServices.PostCodes.GetPostCodeJson(prefixText, count); } And in aspx i do this that: <script> $(document).ready(function() { $("#<%=pc.ClientID %>").autocomplete( baseUrl + "WebServices/Autocomplete.asmx/GetPostCodesCompletionListJson", { parse: function(data) { var array = new Array(); for (var i = 0; i < data.length; i++) { var datum = data[i]; var name = datum.Text; var display = name; array[array.length] = { data: datum, value: display, result: datum.Value }; } return array; }, dataType: "xml" }); }); </script> and when you enter something in the box i got an error: Request format is unrecognized for URL unexpectedly ending in '/GetPostCodesCompletionListJson What am I doing wrong??

  • Form dependency manager

    - by user225269
    Need help in form dependency manager javascript: As you can see the checkbox below depends on either of the two criteria (the info=student or the info=all). I've come up with the code below based on this: DEPENDS ON name [BEING value] [OR name [BEING value]] CONFLICTS WITH name [BEING value] from this site: http://www.dynamicdrive.com/dynamicindex16/formdependency.htm Here's the code: <tr> <td> <input type="hidden" name="yr"> <label> <input type="checkbox" name="yr" value="year" class="DEPENDS ON info BEING student OR info BEING all"> Year</label> </td> </tr>

  • Searches (and general querying) with HBase and/or Cassandra (best practices?)

    - by alexeypro
    I have User model object with quite few fields (properties, if you wish) in it. Say "firstname", "lastname", "city" and "year-of-birth". Each user also gets "unique id". I want to be able to search by them. How do I do that properly? How to do that at all? My understanding (will work for pretty much any key-value storage -- first goes key, then value) u:123456789 = serialized_json_object ("u" as a simple prefix for user's keys, 123456789 is "unique id"). Now, thinking that I want to be able to search by firstname and lastname, I can save in: f:Steve = u:384734807,u:2398248764,u:23276263 f:Alex = u:12324355,u:121324334 so key is "f" - which is prefix for firstnames, and "Steve" is actual firstname. For "u:Steve" we save as value all user id's who are "Steve's". That makes every search very-very easy. Querying by few fields (properties) -- say by firstname (i.e. "Steve") and lastname (i.e. "l:Anything") is still easy - first get list of user ids from "f:Steve", then list from "l:Anything", find crossing user ids, an here you go. Problems (and there are quite a few): Saving, updating, deleting user is a pain. It has to be atomic and consistent operation. Also, if we have size of value limited to some value - then we are in (potential) trouble. And really not of an answer here. Only zipping the list of user ids? Not too cool, though. What id we want to add new field to search by. Eventually. Say by "city". We certainly can do the same way "c:Los Angeles" = ..., "c:Chicago" = ..., but if we didn't foresee all those "search choices" from the very beginning, then we will have to be able to create some night job or something to go by all existing User records and update those "c:CITY" for them... Quite a big job! Problems with locking. User "u:123" updates his name "Alex", and user "u:456" updates his name "Alex". They both have to update "f:Alex" with their id's. That means either we get into overwriting problem, or one update will wait for another (and imaging if there are many of them?!). What's the best way of doing that? Keeping in mind that I want to search by many fields? P.S. Please, the question is about HBase/Cassandra/NoSQL/Key-Value storages. Please please - no advices to use MySQL and "read about" SELECTs; and worry about scaling problems "later". There is a reason why I asked MY question exactly the way I did. :-)

  • Conditional Validation using JQuery Validation Plugin

    - by Steve Kemp
    I have a simple html form that I've added validation to using the JQuery Validation plugin. I have it working for single fields that require a value. I now need to extend that so that if a user answers Yes to a question they must enter something in the Details field, otherwise the Details field can be left blank. I'm using radio buttons to display the Yes/No. Here's my complete html form - I'm not sure where to go from here: <script type="text/javascript" charset="utf-8"> $.metadata.setType("attr", "validate"); $(document).ready(function() { $("#editRecord").validate(); }); </script> <style type="text/css"> .block { display: block; } form.cmxform label.error { display: none; } </style> </head> <body> <div id="header"> <h1> Questions</h1> </div> <div id="content"> <h1> Questions Page 1 </h1> </div> <div id="content"> <h1> </h1> <form class="cmxform" method="post" action="editrecord.php" id="editRecord"> <input type="hidden" name="-action" value="edit"> <h1> Questions </h1> <table width="46%" class="record"> <tr> <td width="21%" valign="top" class="field_name_left"><p>Question 1</p></td> <td width="15%" valign="top" class="field_data"> <label for="Yes"> <input type="radio" name="Question1" value="Yes" validate = "required:true" /> Yes </label> <label for="No"> <input type="radio" name="Question1" value="No" /> No </label> <label for="Question1" class="error">You must answer this question to proceed</label> </td> <td width="64%" valign="top" class="field_data"><strong>Details:</strong> <textarea id = "Details1" class="where" name="Details1" cols="25" rows="2"></textarea></td> </tr> <tr> <td valign="top" class="field_name_left">Question 2</td> <td valign="top" class="field_data"> <label for="Yes"> <input type="radio" name="Question2" value="Yes" validate = "required:true" /> Yes </label> <label for="No"> <input type="radio" name="Question2" value="No" /> No </label> <label for="Question2" class="error">You must answer this question to proceed</label> </td> <td valign="top" class="field_data"><strong>Details:</strong> <textarea id = "Details2" class="where" name="Details2" cols="25" rows="2"></textarea> </td> </tr> <tr class="submit_btn"> <td colspan="3"> <input type="submit" name="-edit" value="Finish"> <input type="reset" name="reset" value="Reset"> </td> </tr> </table> </form> </div> </body> </html>

  • c# inheriting generic collection and serialization...

    - by Stecy
    Hi, The setup: class Item { private int _value; public Item() { _value = 0; } public int Value { get { return _value; } set { _value = value; } } } class ItemCollection : Collection<Item> { private string _name; public ItemCollection() { _name = string.Empty; } public string Name { get {return _name;} set {_name = value;} } } Now, trying to serialize using the following code fragment: ItemCollection items = new ItemCollection(); ... XmlSerializer serializer = new XmlSerializer(typeof(ItemCollection)); using (FileStream f = File.Create(fileName)) serializer.Serialize(f, items); Upon looking at the resulting XML I see that the ItemCollection.Name value is not there! I think what may be happening is that the serializer sees the ItemCollection type as a simple Collection thus ignoring any other added properties... Is there anyone having encountered such a problem and found a solution? Regards, Stécy

  • CM_Get_Device_ID gets correct values from win7 but not xp

    - by Jon W. Jones
    When using CM_Get_Device_ID(...) I am getting the correct value from windows 7. When using windows xp I am getting an incorrect value. For Example, on xp I get "USB\VID_2132&PID_0001\5&36FF4167&0&7" and on 7 I get "USB\VID_2132&PID_0001\413031000576". The value after the \ on PID is our serial number and it is correct on 7 but xp keeps giving back what appears to be a nonsensical value. My question is has anyone else encountered this and know of a workaround?

  • Efficiently storing a list of prime numbers

    - by eSKay
    This article says: Every prime number can be expressed as 30k±1, 30k±7, 30k±11, or 30k±13 for some k. That means we can use eight bits per thirty numbers to store all the primes; a million primes can be compressed to 33,334 bytes "That means we can use eight bits per thirty numbers to store all the primes" This "eight bits per thirty numbers" would be for k, correct? But each k value will not necessarily take-up just one bit. Shouldn't it be eight k values instead? "a million primes can be compressed to 33,334 bytes" I am not sure how this is true. We need to indicate two things: VALUE of k (can be arbitrarily large) STATE from one of the eight states (-13,-11,-7,-1,1,7,11,13) I am not following how 33,334 bytes was arrived at, but I can say one thing: as the prime numbers become larger and larger in value, we will need more space to store the value of k. How, then can we fix it at 33,334 bytes?

  • How to create a column that can never be updated?

    - by Randy Minder
    In SQL Server 2008, is it possible to create a column that can have a value inserted into it, but can never be updated? In other words, the column can have an initial value inserted into it, but once it contains a non-null value, it can never be changed. If possible, I would prefer to do it without using a trigger. Thanks - Randy

  • How do I retrieve the zero-based index of the selected option in a select box?

    - by Ben McCormack
    Let's say I have the following in my HTML code: <select name="Currency" id="Currency"> <option value="0.85">Euro</option> <option value="110.33">Japanese Yen</option> <option value="1.2">Canadian Dollars</option> </select> Using jQuery, I can use $("#Currency").val() to give me the selectd value, and I can use $("#Currency :selected").text() to get the selected text. What do I need to do to get the zero-based index (in this case, 0, 1, or 2) of the current selection?

  • What's the order of execution when using IDataErrorInfo?

    - by Benny Jobigan
    Many times with WPF, we use INotifyPropertyChanged and IDataErrorInfo to enable binding and validation on our data objects. I've got a lot of properties that look like this: public SomeObject SomeData { get { return _SomeData; } set { _SomeData = value; OnPropertyChanged("SomeData"); } } Of course, I have an appropriate overridden IDataErrorInfo.this[] in my class to do validation. Question 1) In a binding situation, what happens? For example: User enters new data. Binding writes data to property. Property set method is executed. Binding checks this[] for validation. If the data is invalid, the binding sets the property back to the old value. Property set method is executed again. This is important if you are adding "hooks" into the set method, like: public string PathToFile { get { return _PathToFile; } set { if (_PathToFile != value && // prevent unnecessary actions OnPathToFileChanging(value)) // allow subclasses to do something or stop the setter { _PathToFile = value; OnPathToFileChanged(); // allow subclasses to do something afterwards OnPropertyChanged("PathToFile"); } } }

  • rich suggestions - why input is null? (seam framework)

    - by Cristian Boariu
    Hi, I'm trying to build a rich suggestions and i do not understand WHY the input value is null... I mean, why inputText value is not taken when i enter something. The .xhtml code: <h:inputText value="#{suggestion.input}" id="text"> </h:inputText> <rich:suggestionbox id="suggestionBoxId" for="text" tokens=",[]" suggestionAction="#{suggestion.getSimilarSpacePaths()}" var="result" fetchValue="#{result.path}" first="0" minChars="2" nothingLabel="No similar space paths found" columnClasses="center" > <h:column> <h:outputText value="#{result.path}" style="font-style:italic"/> </h:column> </rich:suggestionbox> and action class: @Name("suggestion") @Scope(ScopeType.CONVERSATION) public class Suggestion { @In protected EntityManager entityManager; private String input; public String getInput() { return input; } public void setInput(final String input) { this.input = input; } public List<Space> getSimilarSpacePaths() { List<Space> suggestionsList = new ArrayList<Space>(); if (!StringUtils.isEmpty(input) && !input.equals("/")) { final Query query = entityManager.createNamedQuery("SpaceByPathLike"); query.setParameter("path", input + '%'); suggestionsList = (List<Space>) query.getResultList(); } return suggestionsList; } } So, input beeing null, suggestionList is always empty... Why input's value is not posted?

  • IComparable not included when serializing in WCF

    - by djerry
    Hey guys, I have a list i'm filling at server side. It's a list of "User", which implements IComparable. Now when WCF is serializing the data, i guess it's not including the CompareTo method. This is my Object class : [DataContract] public class User : IComparable { private string e164, cn, h323; private int id; private DateTime lastActive; [DataMember] public DateTime LastActive { get { return lastActive; } set { laatstActief = value; } } [DataMember] public int Id { get { return id; } set { id = value; } } [DataMember] public string H323 { get { return h323; } set { h323 = value; } } [DataMember] public string Cn { get { return cn; } set { cn = value; } } [DataMember] public string E164 { get { return e164; } set { e164 = value; } } public User() { } public User(string e164, string cn, string h323, DateTime lastActive) { this.E164 = e164; this.Cn = cn; this.H323 = h323; this.LastActive= lastActive; } [DataMember] public string ToStringExtra { get { if (h323 != "/" && h323 != "") return h323 + " (" + e164 + ")"; return e164; } set { ;} } public override string ToString() { if (Cn.Equals("Trunk Line") || Cn.Equals("")) if (h323.Equals("")) return E164; else return h323; return Cn; } public int CompareTo(object obj) { User user = (User)obj; return user.LastActive.CompareTo(this.LastActive); } } Is it possible to get the CompareTo method to reach the client? Putting [DataMember] isn't the solution as i tried it ( i know...). Thanks in advance.

  • Why does multiplying a double by -1 not give the negative of the current answer

    I am trying to multiply a double value by -1 to get the negative value. It continues to give me a positive value double man = Double.parseDouble(mantissa); double exp; if(sign.equals("plus")){ exp = Double.parseDouble(exponent); } else { exp = Double.parseDouble(exponent); exp = exp*-1; } System.out.println(man+" - "+sign+" - "+exp); The printed result is 13.93 - minus - 2.0 which is correct except that 2.0 should be -2.0

  • calll html button onclick event from asp server side login authenticate event

    - by CraigJSte
    Need to programmatically click an html button from a login event (code behind? the html button sends variables to Flash using method: no response - with no postback and uses ExternalInterface API via javascript. Going from SWF ASPX is great, but need to send User.Identity to SWF from ASPX via javascript after authenticate with login event which am having impossible time getting to work... (calling HTML event from Login button) tried scripting in javascript to login event with no luck, possibly because postback clears SWF variables - so perhaps keeping separate (login then html send) would work... Here is my relevant code: function sendToActionScript(value) { swfobject.getObjectById("Property").sendToActionScript(value); } </script> <object ..// SWF File embedded> </object <form id="form1" runat="server"> <asp:Login id="login1" OnAuthenticate="login1_Authenticate"/> </form> <form id="form" onsubmit="return false;"> <input type="text" name="input" id="input" value="" runat="server" /> <button id="btnInput" runat="server" causesvalidation="false" visible="true" style="width: 51px" onclick="sendToActionScript(this.form.input.value);" >Send</button><br /> </form> // CODE BEHIND protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { // do something to get User Id and Role //bind the string (user or role) to input.value //then call the HTML button onclick event to send it to SWF file. //which I could put in separate function and call from Login_Authenticate } Can anyone help me I am out of ideas.

  • Can I use a property placeholder with Spring EL?

    - by David Easley
    Before upgrading to Spring 3 I had this in my applicationContext.xml file: <bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor"> <property name="validateRequest" value="${validateRequest}" /> <property name="validateResponse" value="${validateResponse}" /> </bean> where ${validateRequest) and ${validateRequest) refer to properties that may or may not be defined in my properties file. In Spring 2, if these proeprties were not present in the properties file the setters on the bean were not called and so the defaults hard-coded in PolePayloadValidatingInterceptor were used. After upgrading to Spring 3, it seems the behaviour is different: If the properties are not present in the properties file I get the following exception: SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'annotationMapping' defined in class path resource [com/northgateis/pole/ws/applicationContext-ws.xml]: Could not resolve placeholder 'validateRequest' at org.springframework.beans.factory.config.PropertyPlaceholderConfigurer.processProperties(PropertyPlaceholderConfigurer.java:272) at org.springframework.beans.factory.config.PropertyResourceConfigurer.postProcessBeanFactory(PropertyResourceConfigurer.java:75) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:640) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:615) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:405) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:272) I tried dabbling with Spring EL but the following doesn't seem to work: <bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor"> <property name="validateRequest" value="${validateRequest?:true}" /> <property name="validateResponse" value="${validateResponse?:false}" /> </bean> The value after the Elvis operator is always used, even when the properties are defined in the proeprties file. Interesting that the syntax is accepted. Any suggestions?

  • Alright to truncate database tables when also using Hibernate?

    - by Marcus
    Is it OK to truncate tables while at the same time using Hibernate to insert data? We parse a big XML file with many relationships into Hibernate POJO's and persist to the DB. We are now planning on purging existing data at certain points in time by truncating the tables. Is this OK? It seems to work fine. We don't use Hibernate's second level cache. One thing I did notice, which is fine, is that when inserting we generate primary keys using Hibernate's @GeneratedValue where Hibernate just uses a key value one greater than the highest value in the table - and even though we are truncating the tables, Hibernate remembers the prior value and uses prior value + 1 as opposed to starting over at 1. This is fine, just unexpected. Note that the reason we do truncate as opposed to calling delete() on the Hibernate POJO's is for speed. We have gazillions of rows of data, and truncate is just so much faster.

  • c#: Clean way to fit a collection into a multidimensional array?

    - by Rosarch
    I have an ICollection<MapNode>. Each MapNode has a Position attribute, which is a Point. I want to sort these points first by Y value, then by X value, and put them in a multidimensional array (MapNode[,]). The collection would look something like this: (30, 20) (20, 20) (20, 30) (30, 10) (30, 30) (20, 10) And the final product: (20, 10) (20, 20) (20, 30) (30, 10) (30, 20) (30, 30) Here is the code I have come up with to do it. Is this hideously unreadable? I feel like it's more hacky than it needs to be. private Map createWorldPathNodes() { ICollection<MapNode> points = new HashSet<MapNode>(); Rectangle worldBounds = WorldQueryUtils.WorldBounds(); for (float x = worldBounds.Left; x < worldBounds.Right; x += PATH_NODE_CHUNK_SIZE) { for (float y = worldBounds.Y; y > worldBounds.Height; y -= PATH_NODE_CHUNK_SIZE) { // default is that everywhere is navigable; // a different function is responsible for determining the real value points.Add(new MapNode(true, new Point((int)x, (int)y))); } } int distinctXValues = points.Select(node => node.Position.X).Distinct().Count(); int distinctYValues = points.Select(node => node.Position.Y).Distinct().Count(); IList<MapNode[]> mapNodeRowsToAdd = new List<MapNode[]>(); while (points.Count > 0) // every iteration will take a row out of points { // get all the nodes with the greatest Y value currently in the collection int currentMaxY = points.Select(node => node.Position.Y).Max(); ICollection<MapNode> ythRow = points.Where(node => node.Position.Y == currentMaxY).ToList(); // remove these nodes from the pool we're picking from points = points.Where(node => ! ythRow.Contains(node)).ToList(); // ToList() is just so it is still a collection // put the nodes with max y value in the array, sorting by X value mapNodeRowsToAdd.Add(ythRow.OrderByDescending(node => node.Position.X).ToArray()); } MapNode[,] mapNodes = new MapNode[distinctXValues, distinctYValues]; int xValuesAdded = 0; int yValuesAdded = 0; foreach (MapNode[] mapNodeRow in mapNodeRowsToAdd) { xValuesAdded = 0; foreach (MapNode node in mapNodeRow) { // [y, x] may seem backwards, but mapNodes[y] == the yth row mapNodes[yValuesAdded, xValuesAdded] = node; xValuesAdded++; } yValuesAdded++; } return pathNodes; } The above function seems to work pretty well, but it hasn't been subjected to bulletproof testing yet.

  • Adobe Flex Combobox as itemrenderer

    - by JonoB
    I have a flex combobox as a datagrid itemrenderer. However, after selecting an item in the combobox, its necessary to click out of the combo (i.e. into another cell or elsewhere in the app) for the value to be committed to the combo. Prior to this, the combo sits 'proud' of the datagrid and the value hasnt actually been committed. Is there a way to force the value to be immediately committed after an item has been selected and for the combo to 'lose focus'?

  • Position of least significant bit that is set

    - by peterchen
    I am looking for an efficient way to determine the position of the least significant bit that is set in an integer, e.g. for 0x0FF0 it would be 4. A trivial implementation is this: unsigned GetLowestBitPos(unsigned value) { assert(value != 0); // handled separately unsigned pos = 0; while (!(value & 1)) { value >>= 1; ++pos; } return pos; } Any ideas how to squeeze some cycles out of it? (Note: this question is for people that enjoy such things, not for people to tell me xyzoptimization is evil.) [edit] Thanks everyone for the ideas! I've learnt a few other things, too. Cool!
