  • Mysql data convert

    - by Sergio
    Is it possible to do DATE_SUB( ".$date." , INTERVAL 100 DAY ) if the type of the column where the date is stored is varchar(255) or I need to convert that column to "DATE" type?

  • Silverlight Data Access - how to keep the gruntwork on the server

    - by akaphenom
    What technologies are used / recommended for HTTP Rpc Calls from Silverlight. My Server Side stack is JBoss (servlets / json_rpc [jabsorb]), and we have a ton of business logic (object creation, validation, persistence, server side events) in place that I still want to take advantage of. This is our first attempt at bringing an applet style ria to our product, and ideally we keep both HTML and Silverlight versions. For better or worse the powers that be have pushed us down the silverlight path, and while flex / java fx / silverlight is an interesting debate, that question is removed from the equation. We just have to find a way to get silverlight to behave with our classes. Should I be defining .NET Class representation of our JSON objects and the methodology to serialize / deserialize access to those objects? IE "blah.com/dispenseRpc?servlet=xxxx&p1=blah&p2=blahblah creating functions that invoke the web request and convert the incomming response string to objects? Another way would be to reverse engineer the .NET wcf(or whatever) communications and implement the handler on the Java side that invokes the correct server side code and returns what .NET expects back. But that sounds much trickier. T

  • Serializing data from a RSS feed in ASP.NET/C#

    - by DotnetDude
    I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?

  • Validating method arguments with Data Annotation attributes

    - by schemer
    The "Silverlight Business Application" template bundled with VS2010 / Silverlight 4 uses DataAnnotations on method arguments in its domain service class, which are invoked automagically: public CreateUserStatus CreateUser(RegistrationData user, [Required(ErrorMessageResourceName = "ValidationErrorRequiredField", ErrorMessageResourceType = typeof(ValidationErrorResources))] [RegularExpression("^.*[^a-zA-Z0-9].*$", ErrorMessageResourceName = "ValidationErrorBadPasswordStrength", ErrorMessageResourceType = typeof(ValidationErrorResources))] [StringLength(50, MinimumLength = 7, ErrorMessageResourceName = "ValidationErrorBadPasswordLength", ErrorMessageResourceType = typeof(ValidationErrorResources))] string password) { /* do something */ } If I need to implement this in my POCO class methods, how do I get the framework to invoke the validations OR how do I invoke the validation on all the arguments imperatively (using Validator or otherwise?).

  • Finding duplicate files by content across multiple directories

    - by gagneet
    I have downloaded some files from the internet related to a particular topic. Now I wish to check if the files have any duplicates. The issue is that the names of the files would be different, but the content may match. Is there any way to implement some code, which will iterate through the multiple folders and inform which of the files are duplicates?

  • FluentMigrator tutorials

    - by Paja
    Are there any tutorials for FluentMigrator? Some "Getting Started..." tutorial would be just awesome. All I was able to find was FluentMigrator.Tests (unit tests), inside FluentMigrator source, which are not as helpful as "Getting Started..." would be.

  • Python list comprehension to return edge values of a list

    - by mvid
    If I have a list in python such as: stuff = [1, 2, 3, 4, 5, 6, 7, 8, 9] with length n (in this case 9) and I am interested in creating lists of length n/2 (in this case 4). I want all possible sets of n/2 values in the original list, for example: [1, 2, 3, 4], [2, 3, 4, 5], ..., [9, 1, 2, 3] is there some list comprehension code I could use to iterate through the list and retrieve all of those sublists? I don't care about the order of the values within the lists, I am just trying to find a clever method of generating the lists.

  • EnvDTE Retrieving the data type from a CodeElement

    - by chrischu
    I am using EnvDTE to generate some code in my latest project. I have a reference to a CodeClass-Object for a given C#-Class but now I wanted to loop through all of its members (in codeClass.Members) and check their types. However I can't manage to retrieve the type of the given member from the CodeElement-Object that I get when looping through codeClass.Members. How can I retrieve the type (int, string etc.)? PS: Reflection is not an option for my usecase.

  • Finding values from a table that are *not* in a grouping of another table and what group that value

    - by Bkins
    I hope I am not missing something very simple here. I have done a Google search(es) and searched through stackoverflow. Here is the situation: For simplicity's sake let's say I have a table called "PeoplesDocs", in a SQL Server 2008 DB, that holds a bunch of people and all the documents that they own. So one person can have several documents. I also have a table called "RequiredDocs" that simply holds all the documents that a person should have. Here is sort of what it looks like: PeoplesDocs: PersonID DocID -------- ----- 1 A 1 B 1 C 1 D 2 C 2 D 3 A 3 B 3 C RequiredDocs: DocID DocName ----- --------- A DocumentA B DocumentB C DocumentC D DocumentD How do I write a SQL query that returns some variation of: PersonID MissingDocs -------- ----------- 2 DocumentA 2 DocumentB 3 DocumentD I have tried, and most of my searching has pointed to, something like: SELECT DocID FROM DocsRequired WHERE NOT EXIST IN ( SELECT DocID FROM PeoplesDocs) but obviously this will not return anything in this example because everyone has at least one of the documents. Also, if a person does not have any documents then there will be one record in the PeoplesDocs table with the DocID set to NULL. Thank you in advance for any help you can provide, Ben

  • NSPredicate acting strange in NSFetchedResultsController

    - by Scott Langendyk
    I feel as if this should be very simple, but it's behaving strangely. I have 3 entities, with a relationship as such Entity A <-- Entity B <<-- Entity C I have an NSFetchedResults controller and I'm trying to filter the results of Entity A using the following predicate. [NSPredicate predicateWithFormat:@"NONE entityB.entityC == %@", self.entityC]; When I try and run the app, the output shows no results. I can alter the predicate slightly to: [NSPredicate predicateWithFormat:@"ANY entityB.entityC == %@", self.entityC]; And it shows me only the results that I want it to filter out. Why is this happening?

  • Rails transaction: save data in multiple models.

    my models class Auction belongs_to :item belongs_to :user, :foreign_key => :current_winner_id has_many :auction_bids end class User has_many :auction_bids end class AuctionBid belongs_to :user end current usage An item is displayed on the page, the user enters an amount and clicks bid. Controller code might look something like this: class MyController def bid @ab = AuctionBid.new(params[:auction_bid]) @ab.user = current_user if @ab.save render :json => {:response => 'YAY!'} else render :json => {:response => 'FAIL!'} end end end desired functionality This works great so far! However, I need to ensure a couple other things happen. @ab.auction.bid_count needs to be incremented by one. @ab.user.bid_count needs to be incremented by one @ab.auction.current_winner_id needs to be set to @ab.user_id That is, the User and the Auction associated with the AuctionBid need values updated as well in order for the AuctionBid#save to return true.

  • IronPython/C# Float data comparison

    - by Gopalakrishnan Subramani
    We have WPF based application using Prism Framework. We have embedded IronPython and using Python Unit Test framework to automate our application GUI testing. It works very well. We have difficulties in comparing two float numbers. Example class MyClass { public object Value { get; set;} public MyClass() { Value = (float) 12.345; } } In IronPython When I compare the MyClass Instance's Value property with python float value(12.345), it says it doesn't equal This statement raises assert error self.assertEqual(myClassInstance.Value, 12.345) This statement works fine. self.assertEqual(float(myClassInstance.Value.ToString()), 12.345) When I check the type of the type(myClassInstance.Value), it returns Single in Python where as type(12.345) returns float. How to handle the C# float to Python comparison without explicit conversions?

    I have a json array say { "People": { "Person": [ {"FirstName": "John", "LastName": "Smith"} {"FirstName": "Joe", "LastName": "Bloggs"} {"FirstName": "Wendy", "LastName": "Deng"} ] } } And I want to convert this into a javascript array (something like this) var persons = [ ["FirstName", "John", "LastName", "Smith"], ["FirstName", "Joe", "LastName", "Bloggs"], ["FirstName", "Wendy", "LastName": "Deng"] ]; How do I accomplish this? Hope my question makes sense and I realise the javascript array initialization may not be the correct way to put it. Thanks.

  • MySQL - How do I inner join sorting the joined data

    - by Gary
    I'm trying to write a report which will join a person, their work, and their hourly wage at the time of work. I cannot seem to figure out the best way to join the person's cost when the date is less than the date of the work. Let's say a person cost $30 per hour at the start of the year then got a $10 raise o Feb 5 and another on Mar 1. 01/01/2010 $30.00 (per hour) 02/05/2010 $40.00 03/01/2010 $45.00 The person put in hours several days which span the rasies. 01/05/2010 10 hours (should be at $30/hr) 01/27/2010 5 hours (again at $30) 02/10/2010 10 hours (at $40/hr) 03/03/2010 5 hours (at $45/hr) I'm trying to write one SQL statement which will pull the hours, the cost per hour, and the hours*cost. The cost is the hourly rate last entered into the system so the cost date is less than the work date, ordered by cost date limit 1. SELECT person.id, person.name, work.hours, person_costs.value, work.hours * person_costs.value AS value FROM person INNER JOIN work ON (person.id = work.person_id) INNER JOIN person_costs ON (person.id = person_costs.person_id AND person_costs.date < work.date) WHERE person.id = 1234 ORDER BY work.date ASC The problem I'm having, the person_costs isn't ordered by date in descending order. It's pulling out "any" value (naturally sorted by record position) which matches the condition. How do I select the first person_cost value which is older than the work date? Thanks!

  • batch update SharePoint data

    - by Faiz
    Hi, I need to import user profile information to a sharepoint list. Also, the user profile information will be periodically updated to the list , therefore i think i should use a timer job to update the information. Importing for the first time works without any issues. But can you suggest what can be the best way to update information. The update should take care of updating existing records in profile , mark as orphaned for the records that are deleted from user profile and add new records in user profile to the list. Thanks

  • Inserting Large volume of data in SQL Server 2005

    - by Manjoor
    We have a application (written in c#) to store live stock market price in the database (SQL Server 2005). It insert about 1 Million record in a single day. Now we are adding some more segment of market into it and the no of records would be double (2 Millions/day). Currently the average record insertion per second is about 50, maximum is 450 and minimum is 0. To check certain conditions i have used service broker (asynchronous trigger) on my price table. It is running fine at this time(about 35% CPU utilization). Now i am planning to create a in memory dataset of current stock price. we would like to do some simple calculations. I want to know different views of members on this. Please provide your way of dealing with such situation.
