  • WCF DataContract class with methods

    - by jmlaplante
    This is more of a philosophical/best-practice sort of question rather than a technical problem. Are there any strong arguments against writing a DataContract class with methods that are to be used server-side only? Or what about additional properties that are not decorated with the DataMember attribute? For example: [DataContract] public class LogEntry { [DataMember] public string Message { get; set; } [DataMember] public string Severity { get; set; } public string SomeOtherProperty { get; set; } ... public void WriteToDatabase() { ... } } Not doing it seems like an awful lot of extra work that I would prefer to avoid, although using extension methods could make it easier. But, as a good developer, I am wondering if it is bad practice to do so.

  • How can I find all attributes with single quotes in a Sublime Text 2 document and replace with double quotes?

    - by Brandon Durham
    I'm feeling particularly nit-picky today. I'm working in some HTML docs that have single quotes around all attribute values through the docs, like this: <div class='classone classtwo'> I'd love to be able to do a find-and-replace in each doc and replace with double quotes, like this: <div class="classone classtwo"> Many elements in the document will have multiple attributes: <div class='classone classtwo' data-scripts='lazyload'> And some will have the correct double quotes: <div class='classone classtwo' data-scripts="lazyload"> What's the best way to replace all single quotes wrapping values with double?

  • Fastest way to compress a database or .bak file and transfer it

    - by Nai
    As per the question title. I wonder if there are special programmes or commands that makes zipping up a .bak file and transferring it super quick. I read abour xp_cmdshell here but I'm not sure about the speed. My .bak file is about 12 gigs at the moment. Related to this is the possibility of using Red Gate's SQL Data Compare to just transfer the differential data across the network pipeline but I have never used SQL Data Compare before and I'm not sure how it goes about doing INSERTS on tables with Primary Keys and such. Also, not sure about the speed. Does anyone have any experience with this programme or similar programmes? Cheers!

  • Lookup Field as a Site Column via CAML

    - by Rob Windsor
    I'm trying to create a Lookup Field as a Site Column via CAML. The list I want to use as the source of the lookup is created in the Feature Receiver so I don't know it's ID. I've read several blog posts that indicate that I can just put the path to the list in the List attribute. It seems from the comments on these post that this solution works for some people but not for others. I'm in the latter group. When I try to associate a content type that uses the lookup site column I: "Exception from HRESULT: 0x80040E07" <Field ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" StaticName="Test_x0020_Lookup_x0020_Column" DisplayName="Test Lookup Column" Type="Lookup" Required="FALSE" List="Lists/Test" ShowField="Title" PrependId="TRUE" Group="Test Site Columns" /> <ContentType ID="0x0100B6D92594DDCE8E479D0EB0C414C463B0" Name="Test Lookup Content Type" Version="0" Group="Test Content Types"> <FieldRefs> <FieldRef ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" Required="TRUE" /> </FieldRefs> </ContentType>

  • Can expiration policies be configured in entlib caching application block?

    - by stesoc
    Hi, Is there a way to tell a CacheManager that every item added will have the same expiration policy? For example in: <cachingConfiguration defaultCacheManager="DefaultCacheManager"> <cacheManagers> <add name="TestCM" expirationPollFrequencyInSeconds="60" maximumElementsInCacheBeforeScavenging="1000" numberToRemoveWhenScavenging="10" backingStoreName="Null Storage" type="Microsoft.Practices.EnterpriseLibrary.Caching.CacheManager, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> I expected to have some attribute like expirationPolicy="AbsoluteTime" or "SlidingTime" and a expirationValue="..." for specifying the timespan to use. Thanks, s.

  • Stripes link event triggering validation that is incorrect.

    - by Davoink
    I have stripes:link tag in a jsp with an event attribute: <stripes:link href="${actionBean.context.currentStage.stripesForwardAction}" addSourcePage="true" event="showTab2Link"> This triggers the validation to trigger on nested properties: @ValidateNestedProperties({ @Validate(field="county", required=true, minlength=2, maxlength=2, mask="\\d\\d"), @Validate(field="parish", required=true, minlength=3, maxlength=3, mask="\\d\\d\\d"), @Validate(field="holding", required=true, minlength=4, maxlength=4, mask="\\d\\d\\d\\d") }) However this would been fine if the actual values it is validation are not present, but they are present within the html and when debugging the bean. Why would the stripes:link trigger this? If I change it to an stripes:submit then it is fine. thanks, Dave

  • Is it possible to use Dependency Injection/IoC on an ASP.NET MVC FilterAttribute ?

    - by Pure.Krome
    Hi folks, I've got a simple custom FilterAttribute which I use decorate various ActionMethods. eg. [AcceptVerbs(HttpVerbs.Get)] [MyCustomFilter] public ActionResult Bar(...) { ... } Now, I wish to add some logging to this CustomFilter Action .. so being a good boy, I'm using DI/IoC ... and as such wish to use this pattern for my custom FilterAttribute. So if i have the following... ILoggingService and wish to add this my custom FilterAttribute .. i'm not sure how. Like, it's easy for me to do the following... public class MyCustomFilterAttribute : FilterAttribute { public MyCustomFilterAttribute(ILoggingService loggingService) { ... } } But the compiler errors saying the attribute which decorates my ActionMethod (listed above...) requires 1 arg .. so i'm just not sure what to do :(

  • resizing arrays when close to memory capacity

    - by user548928
    So I am implementing my own hashtable in java, since the built in hashtable has ridiculous memory overhead per entry. I'm making an open-addressed table with a variant of quadratic hashing, which is backed internally by two arrays, one for keys and one for values. I don't have the ability to resize though. The obvious way to do it is to create larger arrays and then hash all of the (key, value) pairs into the new arrays from the old ones. This falls apart though when my old arrays take up over 50% of my current memory, since I can't fit both the old and new arrays in memory at the same time. Is there any way to resize my hashtable in this situation Edit: the info I got for current hashtable memory overheads is from here How much memory does a Hashtable use? Also, for my current application, my values are ints, so rather than store references to Integers, I have an array of ints as my values.

  • Data Modeling Help - Do I add another table, change existing table's usage, or something else?

    - by StackOverflowNewbie
    Assume I have the following tables and relationships: Person - Id (PK) - Name A Person can have 0 or more pets: Pet - Id (PK) - PersonId (FK) - Name A person can have 0 or more attributes (e.g. age, height, weight): PersonAttribute _ Id (PK) - PersonId (FK) - Name - Value PROBLEM: I need to represent pet attributes, too. As it turns out, these pet attributes are, in most cases, identical to the attributes of a person (e.g. a pet can have an age, height, and weight too). How do I represent pet attributes? Do I create a PetAttribute table? PetAttribute Id (PK) PetId (FK) Name Value Do I change PersonAttribute to GenericAttribute and have 2 foreign keys in it - one connecting to Person, the other connecting to Pet? GenericAttribute Id (PK) PersonId (FK) PetId (FK) Name Value NOTE: if PersonId is set, then PetId is not set. If PetId is set, PersonId is not set. Do something else?

  • Inspecting a Word mail merge data source programmatically

    - by Guy Marom
    I want to iterate over all rows of a MS-Word mail merge data source and extract the relevant data into an XML. I'm currently using this code: Imports Microsoft.Office.Interop Do objXW.WriteStartElement("Recipient") Dim objDataFields As Word.MailMergeDataFields = DataSource.DataFields For Each FieldIndex As Integer In mdictMergeFields.Keys strValue = objDataFields.Item(FieldIndex).Value If Not String.IsNullOrEmpty(strValue) Then strName = mdictMergeFields(FieldIndex) objXW.WriteElementString(strName, strValue) End If Next objXW.WriteEndElement() If DataSource.ActiveRecord = LastRecord Then Exit Do Else DataSource.ActiveRecord = Word.WdMailMergeActiveRecord.wdNextDataSourceRecord End If Loop And it turns out to be a little sluggish (About 1 second for each row). Is there any way to do it faster? My fantasy is finding a function like MailMergeDataSource.ToDatatable and then inspecting the datatable.

  • Using Enums that are in an external dll C#

    - by user1443233
    I have a project I am working that will involve creating one DLL that will be used across multiple other sites. Inside this DLL we need to reference about 10 Enums. The values of these Enums however will be different for each site the DLL is used on. For example: MyBase.dll may have a class MyClass with an attribute of type MyEnum. MyBase.dll is then referenced in MySite. MyStie will also reference MyEnums.dll which will contain the values for the MyEnum type. Is there any way to accomplish this? While building MyBase.dll, I know what enums will exist in side of MyEnums.dll. The problem is I cannot build MyBase.dll without specifically referenceing the MyEnums.dll, which is not created until the MyBase.dll is used in a specific project. I hope that makes sense and hope I can find an answer here. Thanks.

  • Java - JDBC alternatives

    - by Mike
    Hello, this is just teorethical question. I use JDBC with my Java applications for using database (select, insert, update, delete or whatever). I make "manually" Java classes which will contain data from DB tables (attribute = db column). Than I make querys (ResultSet) and fill those classes with data. I am not sure, if this is the right way. But I've read lot of about JDO and another persistence solutions. Can you please recommend some? Which are modern? Will be used in the future? Some advantages of JDO over JDBC (in simple words). I've been able to google lot of this stuff, but opinions from the "first hand" are always best. Thank you for responses, Mike

  • Can I access the function body of an event listener using nodeJS jsdom

    - by Zhami
    I am using jsdom with nodeJS. I load in a large HTML document, and am using jQuery to navigate the DOM. I have a case where I have an element, and I need to access the function body of an event listener (onclick). The event listener was added in the source HTML: <a href="#" onclick="javascript:window.open('http://<rest-of-url>'); return false;"></a> The onclick attribute of the DOM element is undefined. btw: what I really want to do is get the URL (please note that <rest-of-url> is not what is in the source, a real URL spec is there) that is specified in the source.

  • problem with parsing string from excel file

    - by ohana
    hi, i have ruby code to parse data in excel file using Parseexcel gem. I need to save 2 columns in that file into a Hash, here is my code: worksheet.each { |row| if row != nil key = row.at(1).to_s.strip value = row.at(0).to_s.strip if !parts.has_key?(key) and key.length 0 parts[key] = value end end } however it still save duplicate keys into the hash: "020098-10". I checked the excel file at the specified row and found the difference are " 020098-10" and "020098-10". the first one has a leading space while the second doesn't. I dont' understand is it true that .strip function already remove all leading and trailing white space? also when i tried to print out key.length, it gave me these weird number: 020098-10 length 18 020098-10 length 17 which should be 9....

  • ^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

    - by user293261
    Hello. I'm not really sure what to make of this. The key combination of ^← and ^→ have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy. On one user account, it works fine. On the other, it doesn't. This happened today and nothing significant comes to mind that would have caused some weird keybinding issue. If anyone has heard of or experienced anything like this, I would very much appreciate your advice! Thanks.

  • Is there an easier way to typecast with unknown types?

    - by Adam S
    Hi all. I am writing a function to recurse my XAML and add all the controls to a hashtable, with their names being the keys. Unfortunately it seems like I have to go through and list every possible type: void Recurse_Controls(object start) { string start_type = start.GetType().ToString(); if (start_type == "StackPanel") { ControlsByName.Add(((StackPanel)start).Name, start); foreach (object item in ((StackPanel)start).Children) { Recurse_Controls(item); } } if (start_type == "Grid") { ControlsByName.Add(((Grid)start).Name, start); foreach (object item in ((Grid)start).Children) { Recurse_Controls(item); } } } Is there a simpler way of doing this?

  • jQuery Validation Plugin + equalTo Not Working

    - by Tom Winchester
    Hey guys, Here is what I am currently using to attempt to validate a form. When I press submit with no values entered into the form, I get the error messages for each of the inputs as expected. However, no matter what I put in newpassword2 or newemail2 they never 'pass' validation. I've tried everything from copy and paste to making them one letter each to no success. Perhaps I am not using the equalTo attribute correctly... I've also verified that all the names of the selectors agree with the input id's on the form. Also, all of the inputs are contained within the form, so there aren't any outside of the form tags (I read that was an issue with someone else). $(document).ready(function() { $("#account_data").validate({ rules: { newpassword1: { required: true }, newpassword2: { equalTo: "#newpassword1" }, newemail1: { required: true, email: true }, newemail2: { equalTo: "#newemail1" } } }); }); Any help would be extremely appreciated! THANK YOU!!! -Tom-

  • Sorting of table column by string length not working as intended when done in IB via cocoa - binding

    - by Miraaj
    Hi all, I made a sample application displaying list of employees with their salaries over NSTableView using NSArrayController. Basic functionality is working as intended. Also sorting is working fine when Selector - compare or caseInsensitiveCompare is assigned in attribute pane for table column- employeeName. Problem occurs when I try to sort it by string length by setting selector in IB as - length, for the table column - employeeName. It does sorting by string length but does it inappropriately. It is doing sorting on alternate clicks ie. on first click it sorts the content in table in descending order by length. Then on second click it does not arrange contents in ascending order by length but sets arrow on top as in ascending. Then on third click it arranges contents in ascending order by length but sets arrow on top of table column as in descending and so on... Can anyone suggest if I am wrong somewhere? Thanks, Miraaj

  • How can I access variables outside of current scope in javascript?

    - by sekmet64
    I'm writing some application in javascript and cannot figure it out how to access the variables declared in my function, inside this jquery parse. Inside I can access global variables, but I don't really want to create global vars for these values. Basically I want to extract file names from an xml document in the simulationFiles variable. I check if the node attribute is equal with the simName and extract the two strings inside the xml elements, that part I think it's working. How can I extract those xml elements and append them to local variables? function CsvReader(simName) { this.initFileName = "somepath"; this.eventsFileName = "somepath"; $(simulationFiles).find('simulation').each(function() { if ($(this).attr("name") == simName) { initFileName += $(this).find("init").text(); eventsFileName += $(this).find("events").text(); } }); }

  • Set date format in ruby model (sinatra/datamapper)

    - by Gearóid
    Hi, I have a ruby model that contains a date attribue which I'd like to be able to pass in as a parameter in the format dd/MM/yyyy. However, my sqlite3 db stores the data in yyyy-MM-dd format so when a date like 20/10/2010 gets passed in, it will not be read to the database. I am using the Sinatra framework and using haml for the markup creation. Do I need to write a helper that takes the date string and converts it to the correct format for the db? Or can I set a format type on the models attribute? Thanks.
