• Best practices to develop and maintaing code for complex JQuery/JQueryUI based applications

  - by dafi

  I'm working on my first very complex JQuery based application. A single web page can contain hundreds of JQuery related code for example to JQueryUI dialogs. Now I want to organize code in separated files. For example I'm moving all initialization dialogs code $("#dialog-xxx").dialog({...}) in separated files and due to reuse I wrap them on single function call like dialogs.js function initDialog_1() { $("#dialog-1").dialog({}); } function initDialog_2() { $("#dialog-2").dialog({}); } This simplifies function code and make caller page clear $(function() { // do some init stuff initDialog_1(); initTooltip_2(); }); Is this the correct pattern? Are you using more efficient techniques? I know that splitting code in many js files introduces an ugly band-bandwidth usage so. Does exist some good practice or tool to 'join' files for production environments? I imagine some tool that does more work than simply minimize and/or compress JS code.

• Building a complex view with Three20 - resources?

  - by psychotik

  I'm using three20 for most of my iPhone app. One of the views I need to create is relatively complex. It needs a top bar (under the nav bar) with some controls and label, an image view below this bar (which occupies most of the body) and another bottom bar with more controls and labels (above the tab bar control). I don't have much UI experience - my only experience with anything UI is laying stuff out using CSS, etc on websites. Apple's online doc seems to assume that the reader knows a bunch about rectangles, layouts, frames, etc or is using InterfaceBuilder. And three20 isn't too well documented either. So my question is: Is it possible to design something like what I describe in IB and then still have a three20-based app use it? If so, any tips/pointers on how would be much appreciated. Can you point me to some documentation that explain how views/controls etc are rendered. I'm pretty sure I can figure it out if I find some decent explanation/tutorial for it.

• Complex derived attributes in Django models

  - by rabidpebble

  What I want to do is implement submission scoring for a site with users voting on the content, much like in e.g. reddit (see the 'hot' function in http://code.reddit.com/browser/sql/functions.sql). My submission model currently keeps track of up and down vote totals. Currently, when a user votes I create and save a related Vote object and then use F() expressions to update the Submission object's voting totals. The problem is that I want to update the score for the submission at the same time, but F() expressions are limited to only simple operations (it's missing support for log(), date_part(), sign() etc.) From my limited experience with Django I can see 4 options here: extend F() somehow (haven't looked at the code yet) to support the missing SQL functions; this is my preferred option and seems to fit within the Django framework the best define a scoring function (much like reddit's 'hot' function) in my database, and have Django use the value of that function for the value of the score field; as far as I can tell, #2 is not possible wrap my two step voting process in a suitably isolated transaction so that I can calculate the voting totals in Python and then update the Submission's voting totals without fear that another vote against the submission could be added/changed in the meantime; I'm hesitant to take this route because it seems overly complex - what is a "suitably isolated transaction" in this case anyway? use raw SQL; I would prefer to avoid this entirely -- what's the point of an ORM if I have to revert to SQL for such a common use case as this! (Note that this coming from somebody who loves sprocs, but is using Django for ease of development.) Before I embark on this mission to extend F() (which I'm not sure is even possible), am I about to reinvent the wheel? Is there a more standard way to do this? It seems like such a common use case and yet in an hour of searching I have yet to find a common solution...

• ASP.Net MVC vs ASP.Net for Complex workflows

  - by Grant Sutcliffe

  I have just become involved in migrating a series of complex workflows with InfoPath UIs to Web-based UIs. I am new to ASP.Net MVC but have started to evaluate it as the technology versus classic ASP.Net for the job. As is typical of most workflows, in each state there are a number of business rules that determine (a) who can view what content; (2) who can edit what content; (3) what the user action options might be (Edit; Reject; Approve), etc. In essence, there is a lot of logic that needs to be applied to each request before presenting the appropriate view. Being more experienced in ASP.Net, I know that presenting the form(s) as required can be easily achieved through code behind pages (enable / disable / hide fields). I have not seen how this can be achieved with ASP.Net MVC (but am realising that new thinking is required of me when working with MVC - ‘Give only the content on a particular View + limited user action options’). Therefore, if using ASP.Net MVC, it looks like I would need to create a lot of views. Much of the content in each view would be the same. Only field enabled status or buttons would differ in most instances for these views in each state. For example: Step01Initiate (‘Has Save’ button); Step01OriginatorView (has ‘Edit’ Button) ; Step01OriginatorEdit (has ‘Save’ button); Step01Review (has ‘Accept’ / ‘Reject’ buttons); Step01ReviewReject (for reviewer notes; has ‘Save’ / ‘Cancel’ buttons). With workflows of up to six states, this would result in a lot of views. I can see the advantages of choosing ASP.MVC (1) ‘thin’ Views in terms of content; and (2) with logic consolidation in Controllers and different Models. Am I thinking along the right lines in terms of applying the MVC – ‘plenty of views’; or is there a better way to achieve my goal (using ASP.Net MVC or classic ASP.Net)?

• Managing/Storing complex application form

  - by mickyjtwin

  I am developing an online application form, which can be of two categories, either domestic/international. Each different type has commong questions, and also specific questions. They are approx 6 pages/steps of questions. The application form can also be saved at the end of each step, and can be completed at a later date. Some questions will vary depending on answers to previous questions, so there are some complex business rules. In terms of storage of results, would it be best to store the answers in and XML field in SQL? What would be the best way to reference a question to an answer. There is no need for the form to be dynamic in rendering questions etc. e.g. <Application id="123" type="Domestic"> <Answers> <EmailAddress>[email protected]</EmailAddress> <HomePhone>555-5555</HomePhone> <Suburb>MySuburb</Suburb> <Guardians> <Guardian type="Mother"> <FirstName>Mom</FirstName> </Guardian> </Guardians> <Answers> </Application>

• Unit test complex classes with many private methods

  - by Simon G

  Hi, I've got a class with one public method and many private methods which are run depending on what parameter are passed to the public method so my code looks something like: public class SomeComplexClass { IRepository _repository; public SomeComplexClass() this(new Repository()) { } public SomeComplexClass(IRepository repository) { _repository = repository; } public List<int> SomeComplexCalcualation(int option) { var list = new List<int>(); if (option == 1) list = CalculateOptionOne(); else if (option == 2) list = CalculateOptionTwo(); else if (option == 3) list = CalculateOptionThree(); else if (option == 4) list = CalculateOptionFour(); else if (option == 5) list = CalculateOptionFive(); return list; } private List<int> CalculateOptionOne() { // Some calculation } private List<int> CalculateOptionTwo() { // Some calculation } private List<int> CalculateOptionThree() { // Some calculation } private List<int> CalculateOptionFour() { // Some calculation } private List<int> CalculateOptionFive() { // Some calculation } } I've thought of a few ways to test this class but all of them seem overly complex or expose the methods more than I would like. The options so far are: Set all the private methods to internal and use [assembly: InternalsVisibleTo()] Separate out all the private methods into a separate class and create an interface. Make all the methods virtual and in my tests create a new class that inherits from this class and override the methods. Are there any other options for testing the above class that would be better that what I've listed? If you would pick one of the ones I've listed can you explain why? Thanks

• XmlAttribute/XmlText cannot be used to encode complex type

  - by Conrad C

  I want to serialize a class Ticket into xml. I get the error :"XmlAttribute/XmlText cannot be used to encode complex type" because of my customfield class. This is how the xml for customfields should look like ( the attribute array is nesseray but I don't understand how to create it): <custom_fields type="array"> <custom_field name="Standby Reason" id="6"> <value/> </custom_field> <custom_field name="Close Date" id="84"> Class Ticket public class Ticket { [XmlElement("custom_fields")] public CustomFields Custom_fields { get; set; } Class CustomFields [Serializable] public class CustomFields { [XmlAttribute("array")] public List<CustomField> custom_field { get; set; } Class CustomField [Serializable] public class CustomField { [XmlIgnore] public string Name { get; set; } [XmlElement] public int Id { get; set; } [XmlElement] public string Value { get; set; }

• Representing complex scheduled reoccurance in a database

  - by David Pfeffer

  I have the interesting problem of representing complex schedule data in a database. As a guideline, I need to be able to represent the entirety of what the iCalendar -- ics -- format can represent, but in a database. I'm not actually implementing anything relating to ics, but it gives a good scope of the type of rules I need to be able to model. I need to allow allow representation of a single event or a reoccurring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November annually, or the 25th of December annually, or every two weeks starting November 2 and continuing until September 8 the following year. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For example, given January 15, 2010 at 10:00 AM through January 15, 2010 at 11:00 AM, find all schedules that match at least part of that time. (i.e. a schedule that covers 10:30 - 11:00 still matches.) Any suggestions? I looked at http://stackoverflow.com/questions/1016170/how-would-one-represent-scheduled-events-in-an-rdbms but it doesn't cover the scope of the type of reoccurance rules I'd like to model.

• Modeling complex hierarchies

  - by jdn

  To gain some experience, I am trying to make an expert system that can answer queries about the animal kingdom. However, I have run into a problem modeling the domain. I originally considered the animal kingdom hierarchy to be drawn like -animal -bird -carnivore -hawk -herbivore -bluejay -mammals -carnivores -herbivores This I figured would allow me to make queries easily like "give me all birds", but would be much more expensive to say "give me all carnivores", so I rewrote the hierarchy to look like: -animal -carnivore -birds -hawk -mammals -xyz -herbivores -birds -bluejay -mammals But now it will be much slower to query "give me all birds." This is of course a simple example, but it got me thinking that I don't really know how to model complex relationships that are not so strictly hierarchical in nature in the context of writing an expert system to answer queries as stated above. A directed, cyclic graph seems like it could mathematically solve the problem, but storing this in a relational database and maintaining it (updates) would seem like a nightmare to me. I would like to know how people typically model such things. Explanations or pointers to resources to read further would be acceptable and appreciated.

• Strange behavior with complex Q object filter queries in Django

  - by HWM-Rocker

  Hi I am trying to write a tagging system for Django, but today I encountered a strange behavior in filter or the Q object (django.db.models.Q). I wrote a function, that converts a search string into a Q object. The next step would be to filter the TaggedObject with these query. But unfortunately I get a strange behavior. when I search (id=20) = Q: (AND: ('tags__tag__id', 20)) and it returns 2 Taged Objects with the ID 1127 and 132 when I search (id=4) = Q: (AND: ('tags__tag__id', 4)) and it returns also 2 Objects, but this time 1180 and 1127 until here is everything fine, but when i make a little bit more complex query like (id=4) or (id=20) = Q: (OR: ('tags__tag__id', 4), ('tags__tag__id', 20)) then it returns 4(!) Objects 1180, 1127, 1127, 132 But the object with the ID 1127 is returned twice, but thats not the behaviour I want. Do I have to live with it, and uniqify that list or can I do something different. The representation of the Q object looks fine for me. But the worst is now, when I search for (id=20) and (id=4) = Q: (AND: ('tags__tag__id', 20), ('tags__tag__id', 4)) then it returns no object at all. But why? The representation should be ok and the object with the id 1127 is tagged by both. What am I missing? Here are also the relevant parts of the classes, that are involved: class TaggedObject(models.Model): """ class that represent a tagged object """ tags = generic.GenericRelation('ObjectTagBridge', blank=True, null=True) class ObjectTagBridge(models.Model): """ Help to connect a generic object to a Tag. """ # pylint: disable-msg=W0232,R0903 content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') tag = models.ForeignKey('Tag') class Tag(models.Model): ...

• How to Declare Complex Nested C# Type for Web Service

  - by TheArtTrooper

  I would like to create a service that accepts a complex nested type. In a sample asmx file I created: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class ServiceNest : System.Web.Services.WebService { public class Block { [XmlElement(IsNullable = false)] public int number; } public class Cell { [XmlElement(IsNullable = false)] public Block block; } public class Head { [XmlElement(IsNullable = false)] public Cell cell; } public class Nest { public Head head; } [WebMethod] public void TakeNest(Nest nest) { } } When I view the asmx file in IE the test page shows the example SOAP post request as: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <TakeNest xmlns="http://schemas.intellicorp.com/livecompare/"> <nest> <head> <cell> <block xsi:nil="true" /> </cell> </head> </nest> </TakeNest> </soap:Body> </soap:Envelope> It hasn't expanded the <block> into its number member. Looking at the WSDL, the types all look good. So is this just a limitation of the post demo page creator? Thanks.

• Hashing the state of a complex object in .NET

  - by Jan

  Some background information: I am working on a C#/WPF application, which basically is about creating, editing, saving and loading some data model. The data model contains of a hierarchy of various objects. There is a "root" object of class A, which has a list of objects of class B, which each has a list of objects of class C, etc. Around 30 classes involved in total. Now my problem is that I want to prompt the user with the usual "you have unsaved changes, save?" dialog, if he tries to exit the program. But how do I know if the data in current loaded model is actually changed? There is of course ways to solve this, like e.g. reloading the model from file and compare against the one in memory value by value or make every UI control set a flag indicating the model has been changed. Now instead, I want to create a hash value based on the model state on load and generate a new value when the user tries to exit, and compare those two. Now the question: So inspired of that, I was wondering if there exist some way to generate a hash value from the (value)state of some arbitrary complex object? Preferably in a generic way, e.g. no need to apply attributes to each involved class/field. One idea could be to use some of .NET's serialization functionality (assuming it will work out-of-the-box in this case) and apply a hash function to the content of the resulting file. However, I guess there exist some more suitable approach. Thanks in advance.

• using .append to build a complex menu

  - by gneandr

  To build a menu block which should be switchable with hide/unhide of the menu items, I'm using .append html. The code idea is this: navigat += '<h3 class="infoH3"> <a id="' + menuID +'"' + ' href="javascript:slideMenu(\'' + menuSlider + '\');">' + menuName + '</a></h3>'; navigat += '<div id="' + menuSlider + '" style="display:none">'; navigat += ' <ul>'; navigat += ' <li>aMenu1</li>' navigat += ' <li>aMenu2</li>' navigat += ' <li>aMenu3</li>' navigat += ' </ul>'; navigat += '<!-- menuName Slider --></div>'; $("#someElement").append (navigat); This is doing well .. so far. But the point is:: I use JS to read the required menu items (eg. 'aMenu1' together with title and/or link info) from a file to build all that, eg. for 'aMenu1' a complex is composed and $("#someElement").append(someString) is used to add that the 'someElement'. At the moment I build those html elements line by line. Also OK .. as far as the resulting string has the opening and closing tag, eg. "<li>aMenu2</li>". As can be seen from above posted code there is a line "<div id="' + menuSlider + '" style="display:none">". Appending that -- AFAIS -- the .append is automatically (????) adding "</div>" which closes the statement. That breaks my idea of the whole concept! The menu part isn't included in the 'menuSlider '. QQ: How to change it -- NOT to have that "</div" added to it?? Günter

• Complex Quary on cassandra

  - by Sadiqur Rahman

  I have heard on cassandra database engine few days ago and searching for a good documentation on it. after studying on cassandra I got cassandra is more scalable than other data engine. I also read on Amazon SimpleDB but as SimpleDB has a limitation 10GB/table and Google Datastore is slower than Amazon SimpleDB, I prefer not to use them (Google Datastore, Amazon SimpleDB). So for making our site scaled specially high write rates with massive data, I like to use Cassandra as out Data Engine. But before starting using cassandra I am confused on "How to handle complex data using casssandra". I am giving you the MySQL database structure below, Please read this and give me a good suggestion. Users Table hasColum ID Primary hasColum email Unique hasColum FirstName hasColum LastName Category Table hasColum ID Primary hasColum Parent hasColum Category Posts Table hasColum ID Primary hasColum UID Index foreign key linked to users-ID hasColum CID Index foreign key linked to Category-ID hasColum Title hasColum Post Index hasColum PunDate Comments hasColum ID primary hasColum UID Index foreign key linked to users-ID hasColum PID Index foreign key linked to Posts-ID hasColum Comment User Group hasColum ID primary hasColum Name UserToGroup Table (for many to many relation only) hasColum UID foreign key linked to Users-ID hasColum GID foreign key linked to Group-ID Finally for your information, I like to use SimpleCassie PHP Class http://code.google.com/p/simpletools-php/ So, it will be very helpful if you can give me example using SimpleCassie

• Drupal module for complex hours of operation / office hours

  - by Eronarn

  Background: I am building a website in Drupal that links together a wide variety of social service providers for the purposes of discovery, collaboration, and all that good stuff. The goal is to make a website that is simple to browse for consumers of these services and simple to update for providers of these services. The beta has been very well received, but I want to switch to a different information schema before the site goes live. Specific question: I am looking for a module (or other solution) that... Stores this data in Drupal (i.e., no GCal) Supports a wide variety of repeats Is intuitive for people editing the node (no Cron-style interfaces, please!) I have looked into several modules on drupal.org and none seem to meet all of these criteria. I've also searched here, and while this question is similar: http://stackoverflow.com/questions/2794149/drupal-create-a-node-with-employee-working-hours my needs are too complex for the offered solution. Some of these providers have "hours" such as "the third Wednesday of every month", or "open during Winter months", or separate hotline & office hours. Likewise, the Date Repeat module doesn't cut it as stands currently. I'm comfortable hacking what I need into an existing module - I just don't want to duplicate effort! If you have a suggestion on what module might be a good starting point, I'd appreciate that input, too. Thanks. <3

• Firing PropertyChanged event in a complex, nested type in WPF

  - by John

  Hey I have a question about the PropertyChanged vent firing in WPF whne it is used in a complex type. I have a class called DataStore and a list of Departments (an ObservableCollection), and each department again has a list of Products. Properties in the Product class that are changed also affect properties in the Department and DataStore class. How does each Product notify the Department it belongs to, and the DataStore (which is the mother class of all) that one or more of its properties have changed their values? Example: a product has a property NumberSoldToday and is bound. The Department has a property called TotalNumberOfProductsSold: public int TotalNumberOfProductsSold { get { int result = 0; foreach(Product p in this.products) result += p.NumberSoldToday; return result; } } And the data store has a property TotalProductsSold (for all departments): public int TotalProductsSold { get { int result = 0; foreach(Product p in this.deparments) result += p.TotalNumberOfProductsSold; return result; } } If all these properties are bound, and the innermost property changes, it must somehow notify that the value of the other 2 changed as well. How? The only way I can see this happening is to hook up the PropertyChanged event in each class. Th event must also fire when deleting, adding to the collection of products and deparments, respectively. Is there a better, more clever way to do this?

• Forcing size of a complex Flash object.

  - by John

  As I've found recently, setting width/height properties on a Sprite only forces the Sprite to fit the given dimensions by scaling the actual size, which is calculated by Flash based on the rendered content. This leaves me confused. If I have a custom Sprite subclass which draws using Graphics, how can I do layout before an initial render - the size will be zero until it is first drawn? For a more complex issue, let's say I have a 2D game world with objects spread over a wide area with world coordinates from (0,0) to (5000,5000), where each object has a size of maybe up to 100x100. I want to have a Flash component which is the "game window", and has a fixed size like 400x300, rendering part of the game world. So how do I force the game window size to 400x300 pixels? I can draw a 400x300 rectangle to get the size correct but then if I draw any objects which are partly in-view, they can screw this up. Is the right approach to provide a custom setSize(w,h) method which is used rather than width & height setters? But even so, is there no way to make a Sprite force to the size I want? Do you really have to catch it every render and re-scale it?

• Spreading dynamic with community structure

  I have a data set which I hope to simulate the spreading dynamic with community structure. The steps I follow is import the data to a complex network with Networkx partition the network into some modules which are known as communities simulate the SIS model and draw plots with and without communities. Something confused me between step 2 and step 3. After partitioning, I get some communities which contains nodes number. The community numbers and nodes numbers are the only input to step 3, and how I simulate SIS with and without communities?

• Eclipselink read complex object model in an ordered way

  - by Raven

  Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

• Complex HashMap has different hashCode after serialization

  - by woezelmann

  I am parsing a xml file into a complex HashMap looking like this: Map<String, Map<String, EcmObject> EcmObject: public class EcmObject implements Comparable, Serializable { private final EcmObjectType type; private final String name; private final List<EcmField> fields; private final boolean pages; // getter, equals, hashCode } EcmObjectType: public enum EcmObjectType implements Serializable { FOLDER, REGISTER, DOCUMENT } EcmField public class EcmField implements Comparable, Serializable { private final EcmFieldDataType dataType; private final EcmFieldControlType controlType; private final String name; private final String dbname; private final String internalname; private final Integer length; // getter, equals, hashCode } EcmFieldDataType public enum EcmFieldDataType implements Serializable { TEXT, DATE, NUMBER, GROUP, DEC; } and EcmFieldControlType public enum EcmFieldControlType implements Serializable{ DEFAULT, CHECKBOX, LIST, DBLIST, TEXTAREA, HIERARCHY, TREE, GRID, RADIO, PAGECONTROL, STATIC; } I have overwritten all hashCode and equal methods by usind commons lang's EqualsBuilder and HashCodeBuilder. Now when I copy a A HashMap this way: Map<String, Map<String, EcmObject>> m = EcmUtil.convertXmlObjectDefsToEcmEntries(new File("e:\\objdef.xml")); Map<String, Map<String, EcmObject>> m2; System.out.println(m.hashCode()); ByteArrayOutputStream baos = new ByteArrayOutputStream(8 * 4096); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(m); ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray()); ObjectInputStream ois = new ObjectInputStream(bais); m2 = (Map<String, Map<String, EcmObject>>) ois.readObject(); System.out.println(m.hashCode()); System.out.println(m2.hashCode()); m.hashCode() is not equal to m2.hashCode() here is my output: -1639352210 -2071553208 1679930154 Another strange thing is, that eg. 10 times m has the same hashcode and suddenly on the 11th time the hashcode is different...

• Problem serializing complex data using WCF

  - by Gustavo Paulillo

  Scenario: WCF client app, calling a web-service (JAVA) operation, wich requires a complex object as parameter. Already got the metadata. Problem: The operation has some required fields. One of them is a enum. In the SOAP sent, isnt the field above (generated metadata) - Im using WCF diagnostics and Windows Service Trace Viewer: [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(TypeName="Consult-Filter", Namespace="http://webserviceX.org/")] public partial class ConsFilter : object, System.ComponentModel.INotifyPropertyChanged { private PersonType customerTypeField; Property: [System.Xml.Serialization.XmlElementAttribute("customer-type", Form=System.Xml.Schema.XmlSchemaForm.Unqualified, Order=1)] public PersonType customerType { get { return this.customerTypeField; } set { this.customerTypeField = value; this.RaisePropertyChanged("customerType"); } } The enum: [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")] [System.SerializableAttribute()] [System.Xml.Serialization.XmlTypeAttribute(TypeName="Person-Type", Namespace="http://webserviceX.org/")] public enum PersonType { /// <remarks/> F, /// <remarks/> J, } The trace log: <MessageLogTraceRecord> <HttpRequest xmlns="http://schemas.microsoft.com/2004/06/ServiceModel/Management/MessageTrace"> <Method>POST</Method> <QueryString></QueryString> <WebHeaders> <VsDebuggerCausalityData>data</VsDebuggerCausalityData> </WebHeaders> </HttpRequest> <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Header> <Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none"></Action> <ActivityId CorrelationId="correlationId" xmlns="http://schemas.microsoft.com/2004/09/ServiceModel/Diagnostics">activityId</ActivityId> </s:Header> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <filter xmlns="http://webserviceX.org/"> <product-code xmlns="">116</product-code> <customer-doc xmlns="">777777777</customer-doc> </filter> </s:Body> </s:Envelope> </MessageLogTraceRecord>

• Mocking objects with complex Lambda Expressions as parameters

  - by iCe

  Hi there, I´m encountering this problem trying to mock some objects that receive complex lambda expressions in my projects. Mostly with with proxy objects that receive this type of delegate: Func<Tobj, Fun<TParam1, TParam2, TResult>> I have tried to use Moq as well as RhinoMocks to acomplish mocking those types of objects, however both fail. (Moq fails with NotSupportedException, and in RhinoMocks simpy does not satisgy expectation). This is simplified example of what I´m trying to do: I have a Calculator object that does calculations: public class Calculator { public Calculator() { } public int Add(int x, int y) { var result = x + y; return result; } public int Substract(int x, int y) { var result = x - y; return result; } } I need to validate parameters on every method in the Calculator class, so to keep with the Single Responsability principle, I create a validator class. I wire everything up using a Proxy class, that prevents having duplicate code: public class CalculatorProxy : CalculatorExample.ICalculatorProxy { private ILimitsValidator _validator; public CalculatorProxy(Calculator _calc, ILimitsValidator _validator) { this.Calculator = _calc; this._validator = _validator; } public int Operation(Func&lt;Calculator, Func&lt;int, int, int&gt;&gt; operation, int x, int y) { _validator.ValidateArgs(x, y); var calcMethod = operation(this.Calculator); var result = calcMethod(x, y); _validator.ValidateResult(result); return result; } public Calculator Calculator { get; private set; } } Now, I´m testing a component that does use the CalculatorProxy, so I want to mock it, for example using Rhino Mocks: [TestMethod] public void ParserWorksWithCalcultaroProxy() { var calculatorProxyMock = MockRepository.GenerateMock&lt;ICalculatorProxy&gt;(); calculatorProxyMock.Expect(x =&gt; x.Calculator).Return(_calculator); calculatorProxyMock.Expect(x =&gt; x.Operation(c =&gt; c.Add, 2, 2)).Return(4); var mathParser = new MathParser(calculatorProxyMock); mathParser.ProcessExpression("2 + 2"); calculatorProxyMock.VerifyAllExpectations(); } However I cannot get it to work! Any ideas about how this can be done? Thanks a lot!

• Expression Too Complex In Access 2007

  - by Jazzepi

  When I try to run this query in Access through the ODBC interface into a MySQL database I get an "Expression too complex in query expression" error. The essential thing I'm trying to do is translate abbreviated names of languages into their full body English counterparts. I was curious if there was some way to "trick" access into thinking the expression is smaller with sub queries, or if someone else had a better idea of how to solve this problem. I thought about making a temporary table and doing a join on it, but that's not supported in Access SQL. Just as an FYI, the query worked fine until I added the big long IFF chain. I tested the query on a smaller IFF chain for three languages, and that wasn't an issue, so the problem definitely stems from the huge IFF chain (It's 26 deep). Also, I might be able to drop some of the options (like combining the different forms of Chinese or Portuguese) As a test, I was able to get the SQL query to work after paring it down to 14 IFF() statements, but that's a far cry from the 26 languages I'd like to represent. SELECT TOP 5 Count( * ) AS [Number of visits by language], IIf(login.lang="ar","Arabic",IIf(login.lang="bg","Bulgarian",IIf(login.lang="zh_CN","Chinese (Simplified Han)",IIf(login.lang="zh_TW","Chinese (Traditional Han)",IIf(login.lang="cs","Czech",IIf(login.lang="da","Danish",IIf(login.lang="de","German",IIf(login.lang="en_US","United States English",IIf(login.lang="en_GB","British English",IIf(login.lang="es","Spanish",IIf(login.lang="fr","French",IIf(login.lang="el","Greek",IIf(login.lang="it","Italian",IIf(login.lang="ko","Korean",IIf(login.lang="hu","Hungarian",IIf(login.lang="nl","Dutch",IIf(login.lang="pl","Polish",IIf(login.lang="pt_PT","European Portuguese",IIf(login.lang="pt_BR","Brazilian Portuguese",IIf(login.lang="ru","Russian",IIf(login.lang="sk","Slovak",IIf(login.lang="sl","Slovenian","IIf(login.lang="fi","Finnish",IIf(login.lang="sv","Swedish",IIf(login.lang="tr","Turkish","Unknown")))))))))))))))))))))))))) AS [Language] FROM login, reservations, reservation_users, schedules WHERE (reservations.start_date Between DATEDIFF('s','1970-01-01 00:00:00',[Starting Date in the Following Format YYYY/MM/DD]) And DATEDIFF('s','1970-01-01 00:00:00',[Ending Date in the Following Format YYYY/MM/DD])) And reservations.is_blackout=0 And reservation_users.memberid=login.memberid And reservation_users.resid=reservations.resid And reservation_users.invited=0 And reservations.scheduleid=schedules.scheduleid And scheduletitle=[Schedule Title] GROUP BY login.lang ORDER BY Count( * ) DESC; @ Michael Todd I completely agree. The list of languages should have been a table in the database and the login.lang should have been a FK into that table. Unfortunately this isn't how the database was written, and it's not really mine to modify. The languages are placed into the login.lang field by the PHP running on top of the database.

• Calling the same xsl:template for different node names of the same complex type

  - by CraftyFella

  Hi, I'm trying to keep my xsl DRY and as a result I wanted to call the same template for 2 sections of an XML document which happen to be the same complex type (ContactDetails and AltContactDetails). Given the following XML: <?xml version="1.0" encoding="UTF-8"?> <RootNode> <Name>Bob</Name> <ContactDetails> <Address> <Line1>1 High Street</Line1> <Town>TownName</Town> <Postcode>AB1 1CD</Postcode> </Address> <Email>[email protected]</Email> </ContactDetails> <AltContactDetails> <Address> <Line1>3 Market Square</Line1> <Town>TownName</Town> <Postcode>EF2 2GH</Postcode> </Address> <Email>[email protected]</Email> </AltContactDetails> </RootNode> I wrote an XSL Stylesheet as follows: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> <PersonsName> <xsl:value-of select="RootNode/Name"/> </PersonsName> <xsl:call-template name="ContactDetails"> <xsl:with-param name="data"><xsl:value-of select="RootNode/ContactDetails"/></xsl:with-param> <xsl:with-param name="elementName"><xsl:value-of select="'FirstAddress'"/></xsl:with-param> </xsl:call-template> <xsl:call-template name="ContactDetails"> <xsl:with-param name="data"><xsl:value-of select="RootNode/AltContactDetails"/></xsl:with-param> <xsl:with-param name="elementName"><xsl:value-of select="'SecondAddress'"/></xsl:with-param> </xsl:call-template> </xsl:template> <xsl:template name="ContactDetails"> <xsl:param name="data"></xsl:param> <xsl:param name="elementName"></xsl:param> <xsl:element name="{$elementName}"> <FirstLine> <xsl:value-of select="$data/Address/Line1"/> </FirstLine> <Town> <xsl:value-of select="$data/Address/Town"/> </Town> <PostalCode> <xsl:value-of select="$data/Address/Postcode"/> </PostalCode> </xsl:element> </xsl:template> </xsl:stylesheet> When i try to run the style sheet it's complaining to me that I need to: To use a result tree fragment in a path expression, either use exsl:node-set() or specify version 1.1 I don't want to go to version 1.1.. So does anyone know how to get the exsl:node-set() working for the above example? Or if someone knows of a better way to apply the same template to 2 different sections then that would also really help me out? Thanks Dave
