• Insert xelements using LINQ Select?

  - by Simon Woods

  I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

• Setting a value into a object using reflection

  - by marionmaiden

  Hello I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime. For example, what I have is this: public class a{ private typeA attr1; private typeB attr2; public typeA getAttr1(){ return attr1; } public typeB getAttr2(){ return attr2; } public void setAttr1(typeA at){ attr1 = at; } public void setAttr2(typeB at){ attr2 = at; } } public class typeA{ public typeA(){ // doesn't matter } } public class typeB{ public typeB(){ // doesn't matter } } So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this: a test = new a(); a.setAttr1(new typeA()); But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.

• Cyclic References and WCF

  - by Kunal

  I have generated my POCO entities using POCO Generator, I have more than 150+ tables in my database. I am sharing POCO entities all across the application layers including the client. I have disabled both LazyLoading and ProxyCreation in my context.I am using WCF on top of my data access and business layer. Now, When I return a poco entity to my client, I get an error saying "Underlying connection was closed" I enabled WCF tracing and found the exact error : Contains cycles and cannot be serialized if reference tracking is disabled. I Looked at MSDN and found solutions like setting IsReference=true in the DataContract method atttribute but I am not decorating my POCO classes with DataContracts and I assume there is no need of it as well. I won't be calling that as a POCO if I decorate a class with DataContract attribute Then, I found solutions like applying custom attribute [CyclicReferenceAware] over my ServiceContracts.That did work but I wanted to throw this question to community to see how other people managed this and also why Microsoft didn't give built in support for figuring out cyclic references while serializing POCO classes

• Cannot access new product attributes in grid display

  - by russjman

  I added a couple new attribute to my products(a boolean "yes/no" fields). They are variables to enable/disable the price from displaying on the product detail page, and grid view. I managed to get it work on the product info page. But on product grid page I cant seem to access those variable. Specifically, the template i am working with is catalog/product/list.phtml. Ive tried adding them in the xml file like this layout/catalog.xml: <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml"> <action method="addAttribute"><name>DisplayPrice</name></action> <action method="addAttribute"><name>CustomOrder</name></action> </block> and I am trying to access the attributes like so in catalog/product/list.phtml: <?php echo $_product->getDisplayPriceName()? "Yes" : "No" ; echo $_product->getCustomOrderName()? "Yes" : "No" ;?> ive also added in the Mage config file app/code/core/Catalog/etc/config.xml: <frontend> <!---- stuff before this --> <product> <collection> <attributes> <name /> <url_key /> <price /> <special_price /> <custom_order /> <!--new attribute --> <display_price /> <!--new attribute --> <special_from_date /> <special_to_date /> <short_description /> <thumbnail /> <small_image /> <image_label /> <thumbnail_label /> <small_image_label /> <tax_class_id /> <status /> <news_from_date /> <news_to_date /> <created_at /> <updated_at /> </attributes> </collection> </product> </frontend> At this point im shooting in the dark. I dont know enough about the Magento backend to know where else i need to go or look. ANY feed back will be greatly appreciated. thanks in advance.

• Are Sphinx & thinking_sphinx really stable? Not indexing Columns

  - by seb

  I'm encountering strange behaviour from thinking_sphinx/sphinx. My define_index block is about 100 lines, so quite a lot of columns i'm indexing. For full-text searching I only need about 10 attributes, for sorting and filtering I have another approximately 50 columns, mostly floats and integers. By filtering I mean using the "with" or "without" options. Searching does not really work consistently. All of a sudden, one attribute fails to filter. Or if I add a new one, it does not work. Only after a lot of tinkering it suddenly starts working. I cannot really reproduce it. Steps I that sometimes lead me to success where: rm -rf db/sphinx change the attribute definition e.g. has some_attribute = has some_attribute, :sortable = true or = has some_attribute, :sortable = true, :as = "some_attribute" restarting the server assigning a new :as name = has some_attribute, :as = "some_attribute_new" (yes, I did rake ts:rebuild or rake ts:in after every step) Does anybody else encounter similar problems?

• Java webapp: where/how to automatically set each picture's width/height

  - by NoozNooz42

  For several reasons, a lot of "webmaster guides" (like Google and Yahoo!'s webmaster guides/guidelines) repeats several times that it is better to always put the width and height attribute of the img tag. One of the most obvious reason is that the elements in the page won't seem to be "jumping around" to a new location after every picture is loaded (always setting the correct width/height sure gets rid of this behavior). And there are other reasons to follow these guidelines / best practices. So: if we consider that these are indeed good practices if there are a lot of pictures and they are changing often if pictures aren't changing between two .war re-deploy (that is: there's no user-contributed picture) if we don't want to manually edit all these width/height attributes How do we automatically/programmatically serve HTML pages where every img tag have their width/height attribute correctly set as the best practice recommend?

• How to Look Up Email by Full Name in Active Directory?

  - by Danny

  I want to search for a user's email by using Active Directory. Available is the user's full name (ex. "John Doe" for the email with an email "[email protected]"). From what I've searched, this comes close to what I'm looking to do -- except that the Filter is set to "SAMAccountName", which is not what I have. Unless I'm misunderstanding, I just need to pick the right attribute and toss in the full name name in the same way. Unfortunately, I don't know what this attribute is, apparently no one has had to ask about searching for information in this manner, and that is a pretty big list (msdn * microsoft * com/en-us/library/ms675090(v=VS.85) * aspx, stackoverflow didn't let me link 2 hyperlinks because I don't have 10 rep) of attributes. Does anyone know how to obtain the user's email address through an Active Directory lookup by using the user's full name?

• Strange thing about .NET 4.0 filesystem enumeration functionality

  - by codymanix

  I just read a page of "Whats new .NET Framework 4.0". I have trouble understanding the last paragraph: To remove open handles on enumerated directories or files Create a custom method (or function in Visual Basic) to contain your enumeration code. Apply the MethodImplAttribute attribute with the NoInlining option to the new method. For example: [MethodImplAttribute(MethodImplOptions.NoInlining)] Private void Enumerate() Include the following method calls, to run after your enumeration code: * The GC.Collect() method (no parameters). * The GC.WaitForPendingFinalizers() method. Why the attribute NoInlining? What harm would inlining do here? Why call the garbage collector manually, why not making the enumerator implement IDisposable in the first place? I suspect they use FindFirstFile()/FindNextFile() API calls for the imlementation, so FindClose() has to be called in any case if the enumeration is done.

• JavaScript check field value based on variable value

  - by Nikita Sumeiko

  I have an anchor like this: <a href="#" rel="1 4 7 18 ">Anchor</a> Where 'rel' attribute values are ids of some items. Than I have a form with an input, where user should type an id and click submit button. On submit button click I need to check the value of input like this: var value = $('a').attr('rel'); if ( value == '1' || value == '4' || value == '7' || value == '18') { // however I need the line above are created dynamically based on 'value' var alert('The id exists'); return false; } else { return true; } So, the question is how to create a line below dynamically based on anchor 'rel' attribute values?! This is the line: if ( value == '1' || value == '4' || value == '7' || value == '18') {

• Restkit Serializing a Boolean from NSNumber

  - by angelokh

  One of managed objects has one attribute 'isMember' represented by NSNumber type. When serialize to Json post body by RestKit, it always give 0/1 instead of YES/NO or true/false. When mapping from json result to objects, RestKit is able to successfully turn YES/NO to NSNumber. What is the way to force serialize the boolean attribute to YES/NO or true/false? Serialize: 0 -> 0, 1 -> 1 Deserialize : YES/true -> 1, NO/false -> 0

• runtime loading of ValidateAntiForgeryToken Salt value

  - by p.campbell

  Consider an ASP.NET MVC application using the Salt parameter in the [ValidateAntiForgeryToken] directive. The scenario is such that the app will be used by many customers. It's not terribly desirable to have the Salt known at compile time. The current strategy is to locate the Salt value in the web.config. [ValidateAntiForgeryToken(Salt = Config.AppSalt)] //Config.AppSalt is a static property that reads the web.config. This leads to a compile-time exception suggesting that the Salt must be a const at compile time. An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type How can I modify the application to allow for a runtime loading of the Salt so that the app doesn't have to be re-salted and recompiled for each customer? Consider that the Salt won't change frequently, if at all, thereby removing the possibility of invalidating form

• WCF hosted in a Web application and compatibility mode

  - by DotnetDude

  I have a WCF service hosted in a web application (IIS). I need to expose 1 end point over wsHttp and the other over netTcp. I am on a IIS7 environment that makes it possible for me to host non HTTP based services. Anyways, when I browse the .svc file using a browser, I get the error: The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application By googling, I realized that WCF runs in two modes - Mixed and ASP.NET compatible. When I apply the attribute [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] However, it appears that once I apply this attribute to the Service Contract implementation, I cannot use a non HTTP binding. How do I set it up so that: I can support non HTTP endpoints I can host the service on a Web app I don't create multiple services one with aspnet compatibility turned on and the other turned off

• EF4 CTP5 Code First approach ignores Table attributes

  - by Justin

  I'm using EF4 CTP5 code first approach but am having trouble getting it to work. I have a class called "Company" and a database table called "CompanyTable". I want to map the Company class to the CompanyTable table, so have code like this: [Table(Name = "CompanyTable")] public class Company { [Key] [Column(Name = "CompanyIdNumber", DbType = "int")] public int CompanyNumber { get; set; } [Column(Name = "CompanyName", DbType = "varchar")] public string CompanyName { get; set; } } I then call it like so: var db = new Users(); var companies = (from c in db.Companies select c).ToList(); However it errors out: Invalid object name 'dbo.Companies'. It's obviously not respecting the Table attribute on the class, even though it says here that Table attribute is supported. Also it's pluralizing the name it's searching for (Companies instead of Company.) How do I map the class to the table name?

• Help Required on track active directory changes

  - by Faiasl Iqbal

  I am going to write a small software to track active directory changes. I need an expert opinion from you. I want to display information about What ( with before and after values), When, Where and Who of any change in AD. I am going to implement this by one of the following way 1. Change Notification Control 2. DirSync Control Both of these method give us the attribute that are changed and we can compare new values with some dump in SQL Server to get old values. My problem is how can I find “Who” has made this change. I have tried but there is no attribute “LastModifiedBy” in active directory. Please give your opinion how can I track who has made this change. --Faisal Iqbal

• Define variable in variable/parameter and use in javascript?

  - by Ross

  I want to defined a variable/parameter in CSS and access it by javascript. What is the best way of doing this? One option I thought of would be to place a cutsom attribute on the body element, then access that attribute via jQuery. A little more info: I'm defining colour sets in CSS. I've created a function with RaphaelJS to draw a gradient background on the page. I want this function to use a highlight colour (which is not used elsewhere on the DOM) which will be defined in the CSS along with the other colour elements. Thanks

• Sum value of XML attributes using PowerShell 2.0

  - by Yooakim

  I have a directory with XML files. I quickly want to go through them and sum upp the value stored in one attribute. I have figured out how to fidn the nodes I am interested in. For example: (Select-Xml -Path .\*.xml -XPath "//*[@Attribue = 'valueImlookingfor']").Count This command gives me the count of elements in all of the XML files in the current directory which has the value "valueImlookingfor" in the "Attribue". I want to sum up all the values of the "Attribute", not count them. What would be the best way to do this in PowerShell? I am new to PowerShell so this may be trivial but un-known to me... All tips are much appreciated :-)

• Error Serializing a CLR object for use in a WCF service

  - by user208662

  Hello, I have written a custom exception object. The reason for this is I want to track additional information when an error occurs. My CLR object is defined as follows: public class MyException : Exception { public override string StackTrace { get { return base.StackTrace; } } private readonly string stackTrace; public override string Message { get { return base.Message; } } private readonly string message; public string Element { get { return element; } } private readonly string element; public string ErrorType { get { return errorType; } } private readonly string errorType; public string Misc { get { return misc; } } private readonly string misc; #endregion Properties #region Constructors public MyException() {} public MyException(string message) : base(message) { } public MyException(string message, Exception inner) : base(message, inner) { } public MyException(string message, string stackTrace) : base() { this.message = message; this.stackTrace = stackTrace; } public MyException(string message, string stackTrace, string element, string errorType, string misc) : base() { this.message = message; this.stackTrace = stackTrace; this.element = element; this.errorType = errorType; this.misc = misc; } protected MyException(SerializationInfo info, StreamingContext context) : base(info, context) { element = info.GetString("element"); errorType = info.GetString("errorType"); misc = info.GetString("misc"); } public override void GetObjectData(SerializationInfo info, StreamingContext context) { base.GetObjectData(info, context); info.AddValue("element", element); info.AddValue("errorType", errorType); info.AddValue("misc", misc); } } I have created a copy of this custom xception in a WP7 application. The only difference is, I do not have the GetObjectData method defined or the constructor with SerializationInfo defined. If I run the application as is, I receive an error that says: Type 'My.MyException' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. If I add the DataContract / DataMember attributes to the class and its appropriate members on the server-side, I receive an error that says: Type cannot be ISerializable and have DataContractAttribute attribute. How do I serialize MyException so that I can pass an instance of it to my WCF service. Please note, I want to use my service from an Android app. Because of this, I don't want to do anything too Microsoft centric. That was my fear with DataContract / DataMember stuff. Thank you so much for your help!

• Redirect away from HTTPS with ASP.NET MVC App

  - by Amadiere

  I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

• Android Market Publishing Issues

  - by Steve

  I have an app which I have just updated to froyo to take advantage of the move to SD card feature. I am now trying to upload the update to the market but I keep getting the following error: "The file is invalid: W/ResourceType( 7193): Bad string block: last string is not 0- terminated ERROR getting 'android:label' attribute: attribute is not a string value". I changed the value in the manifest from "android:label="@string/app_name" " to "android:label="test" " and uploaded it, then it started complaining about the icon, saying that it wasn't a string. Anyone have any ideas? The application part of my manifest is shown below and I'm properly confused. The app compiles into an APK, it even installs and runs fine on my N1 (installing from SD card) it just won't upload to the market. Any help would be greatly appreciated, I have absolutely no idea what's wrong, seems like I've tried everything I can think of including re-installing eclipse. Cheers Steve

• CSS [custom?] attributes

  - by Michael

  radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

  I have a join model in a HABTM relationship with a through association (details below). I 'm trying to find a record....find the value of that records attribute...change the value and update the record but am having a hard time doing it. The model setup is this User.rb has_many :choices has_many :interests, :through => :choices Interest.rb has_many :choices has_many :users, :through => :choices Choice.rb belongs_to :user belongs_to :interest and Choice has the user_id, interest_id, score as fields. And I find the ?object? like so @choice = Choice.where(:user_id => @user.id, :interest_id => interest.id) So the model Choice has an attribute called :score. How do I find the value of the score column....and +1/-1 it and then resave? I tried @choice.score = @choice.score + 1 @choice.update_attributes(params[:choice]) flash[:notice] = "Successfully updated choices value." but I get "undefined method score"......What did i miss?
