  • Most optimal way to convert to date

    - by IMHO
    I have legacy system where all date fields are maintained in YMD format. Example: 20101123 this is date: 11/23/2010 I'm looking for most optimal way to convert from number to date field. Here is what I came up with: declare @ymd int set @ymd = 20101122 select @ymd, convert(datetime, cast(@ymd as varchar(100)), 112) This is pretty good solution but I'm wandering if someone has better way doing it

  • QuestionOrAnswer model?

    - by Mark
    My site has Listings. Users can ask Questions about listings, and the author of the listing can respond with an Answer. However, the Answer might need clarification, so I've made them recursive (you can "answer" an answer). So how do I set up the database? The way I have it now looks like this (in Django-style models): class QuestionOrAnswer(Model): user = ForeignKey(User, related_name='questions') listing = ForeignKey(Listing, related_name='questions') parent = models.ForeignKey('self', null=True, blank=True, related_name='children') message = TextField() But what bugs me is that listing is now an attribute of the answers as well (it doesn't need to be). What happens if the database gets mangled and an answer belongs to a different listing than its parent question? That just doesn't make any sense. We can separate it with polymorphism: QuestionOrAnswer user message created updated Question(QuestionOrAnswer) shipment Answer(QuestionOrAnswer) parent = ForeignKey(QuestionOrAnswer) And that ought to work, but now ever question and answer is split into 2 tables. Is it worth this overhead for clearly defined models?

  • A better UPDATE method in LINQ to SQL

    - by Refracted Paladin
    The below is a typical, for me, Update method in L2S. I am still fairly new to a lot of this(L2S & business app development) but this just FEELs wrong. Like there MUST be a smarter way of doing this. Unfortunately, I am having trouble visualizing it and am hoping someone can provide an example or point me in the right direction. To take a stab in the dark, would I have a Person Object that has all these fields as Properties? Then what, though? Is that redundant since L2S already mapped my Person Table to a Class? Is this just 'how it goes', that you eventually end up passing 30 parameters(or MORE) to an UPDATE statement at some point? For reference, this is a business app using C#, WinForms, .Net 3.5, and L2S over SQL 2005 Standard. Here is a typical Update Call for me. This is in a file(BLLConnect.cs) with other CRUD methods. Connect is the name of the DB that holds tblPerson When a user clicks save() this is what is eventually called with all of these fields having, potentially, been updated-- public static void UpdatePerson(int personID, string userID, string titleID, string firstName, string middleName, string lastName, string suffixID, string ssn, char gender, DateTime? birthDate, DateTime? deathDate, string driversLicenseNumber, string driversLicenseStateID, string primaryRaceID, string secondaryRaceID, bool hispanicOrigin, bool citizenFlag, bool veteranFlag, short ? residencyCountyID, short? responsibilityCountyID, string emailAddress, string maritalStatusID) { using (var context = ConnectDataContext.Create()) { var personToUpdate = (from person in context.tblPersons where person.PersonID == personID select person).Single(); personToUpdate.TitleID = titleID; personToUpdate.FirstName = firstName; personToUpdate.MiddleName = middleName; personToUpdate.LastName = lastName; personToUpdate.SuffixID = suffixID; personToUpdate.SSN = ssn; personToUpdate.Gender = gender; personToUpdate.BirthDate = birthDate; personToUpdate.DeathDate = deathDate; personToUpdate.DriversLicenseNumber = driversLicenseNumber; personToUpdate.DriversLicenseStateID = driversLicenseStateID; personToUpdate.PrimaryRaceID = primaryRaceID; personToUpdate.SecondaryRaceID = secondaryRaceID; personToUpdate.HispanicOriginFlag = hispanicOrigin; personToUpdate.CitizenFlag = citizenFlag; personToUpdate.VeteranFlag = veteranFlag; personToUpdate.ResidencyCountyID = residencyCountyID; personToUpdate.ResponsibilityCountyID = responsibilityCountyID; personToUpdate.EmailAddress = emailAddress; personToUpdate.MaritalStatusID = maritalStatusID; personToUpdate.UpdateUserID = userID; personToUpdate.UpdateDateTime = DateTime.Now; context.SubmitChanges(); } }

  • Displaying success/failure messages from hidden iframe submit

    - by Erik Nelson
    I'm using the hidden iframe method to submit a form with a file upload field. I want to display a message back on the page using javascript and I'm not sure how to do this. If this was just a form with text fields I'd do an AJAX post and respond with a message I'd display in my callback function. I'm just not sure how to accomplish this same task with the hidden iframe method since it is a standard form post.

  • have PDF form, need to port to website

    - by Alex
    So here is what I have: a PDF form (job application) that a client is requesting to put on their website as a form and the data gets sent to them when an applicant on the site fills the form out. My idea is as follows: dissecting the PDF, taking its fields and making the HTML form, then processing on the server side, creating the new PDF and emailing as an attachment to the client. However, something tells me that there is a better, more effective way of doing it. Is that so?

  • Efficient storage/retrieval method for replayable comet style applications (Google Wave, Etherpad)

    - by Gareth Simpson
    I am considering a web application that would have the same kind of multi user, automatic saving, infinite undo / replay capabilities that you see in Google Wave and Etherpad (albeit on a drastically smaller scale and userbase). Before I go away and reinvent the wheel, is this something that has already been addressed as either a piece of technology or library, or even just a design pattern. I know this isn't necessarily the best Stack Overflow question as there is probably not a "right" answer, but my Google-fu has failed me and I'd just like a reading list! Ordinarily I would be developing under python/django but this is not a firm requirement just a preference :)

  • What Web design tool would make a good CityDesk replacement?

    - by Joshua Fox
    I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site. I have used CityDesk, but that is out-of-date, unsupported, and has certain problems. Of course there are lots of tools out there, but I cannot find anything similar to CityDesk: WYSIWYG as well as HTML coding a templating system not overdesigned like, say, Dreamweaver built for developers who understand HTML/JS/CSS but easier to use than hand-coding of PHP, Ruby, or other templates in a text editor supporting the editing of pages by non-developers preferably free I'd also like it to be CSS-aware; and to have lots of free templates available. Or alternatively, static template-based sites are often developed nowadays on the Web using a CMS like Django; is that the way to go? Edit: Namo, DreamWeaver, NetObjects Fusion, Coffee Cup, Evrsoft First Page, and Microsoft Expression might be candidates. I'll appreciate comments on these based on the criteria above.

  • How to Compute a Database Column in .NET

    - by Michael
    I have a Database named CarsType.accdb there are four fields in the data base Item_Name, Item_Num, Item_Qty, Item_Cost. I am able to get the database to display my data in VisualBasic but I am not sure how to get the total cost to appear in my label (lblTotalCost). I prefer doing it in VB versus writing in my access program. All I am wanting to do it multiply item_qty * Item_Cost How would I go about doing that?

  • MS Access ADODB.recordset character limit is 2036!? Can this be increased?

    - by souper-dragon
    In the following AccessVBA code, I am trying to write a record to a memo field called "Recipient_Display": oRec1.Fields("RECIPIENT_DISPLAY") = Left(sRecipientDisplayNames, Len(sRecipientDisplayNames) - 2) When the string contains 2036 characters, the write completes. Above this number I get the following error: Run-time error'-2147217887(80040e21)': Could not update; currently locked by another session on this machine. What is the significance of this number 2036 and is there a property I can adjust that will allow the above update to take place?

  • How can one prevent page breaks between Tables in SQL Reporting Services 2005?

    - by James
    I've been developing an SSRS 2005 report (a form letter) that contains two tables. The first "table" uses DataSet "A" to populate address fields on letterhead. The second table uses DataSet "B" to display a basic list of records that pertain to the addressed party. Even though the two tables are within the same page and all PageBreak* properties are set to "False", SSRS renders the report as two pages. How can I force both tables to render in series, without any forced page breaks?

  • functional dependencies vs type families

    - by mhwombat
    I'm developing a framework for running experiments with artificial life, and I'm trying to use type families instead of functional dependencies. Type families seems to be the preferred approach among Haskellers, but I've run into a situation where functional dependencies seem like a better fit. Am I missing a trick? Here's the design using type families. (This code compiles OK.) {-# LANGUAGE TypeFamilies, FlexibleContexts #-} import Control.Monad.State (StateT) class Agent a where agentId :: a -> String liveALittle :: Universe u => a -> StateT u IO a -- plus other functions class Universe u where type MyAgent u :: * withAgent :: (MyAgent u -> StateT u IO (MyAgent u)) -> String -> StateT u IO () -- plus other functions data SimpleUniverse = SimpleUniverse { mainDir :: FilePath -- plus other fields } defaultWithAgent :: (MyAgent u -> StateT u IO (MyAgent u)) -> String -> StateT u IO () defaultWithAgent = undefined -- stub -- plus default implementations for other functions -- -- In order to use my framework, the user will need to create a typeclass -- that implements the Agent class... -- data Bug = Bug String deriving (Show, Eq) instance Agent Bug where agentId (Bug s) = s liveALittle bug = return bug -- stub -- -- .. and they'll also need to make SimpleUniverse an instance of Universe -- for their agent type. -- instance Universe SimpleUniverse where type MyAgent SimpleUniverse = Bug withAgent = defaultWithAgent -- boilerplate -- plus similar boilerplate for other functions Is there a way to avoid forcing my users to write those last two lines of boilerplate? Compare with the version using fundeps, below, which seems to make things simpler for my users. (The use of UndecideableInstances may be a red flag.) (This code also compiles OK.) {-# LANGUAGE MultiParamTypeClasses, FunctionalDependencies, FlexibleInstances, UndecidableInstances #-} import Control.Monad.State (StateT) class Agent a where agentId :: a -> String liveALittle :: Universe u a => a -> StateT u IO a -- plus other functions class Universe u a | u -> a where withAgent :: Agent a => (a -> StateT u IO a) -> String -> StateT u IO () -- plus other functions data SimpleUniverse = SimpleUniverse { mainDir :: FilePath -- plus other fields } instance Universe SimpleUniverse a where withAgent = undefined -- stub -- plus implementations for other functions -- -- In order to use my framework, the user will need to create a typeclass -- that implements the Agent class... -- data Bug = Bug String deriving (Show, Eq) instance Agent Bug where agentId (Bug s) = s liveALittle bug = return bug -- stub -- -- And now my users only have to write stuff like... -- u :: SimpleUniverse u = SimpleUniverse "mydir"

  • How to implement table-per-concrete-type strategy using entity framework

    Hello Guys! I'm mapping a set of tables that share a common set of fields: So as you can see I'm using a table-per-concrete-type strategy to map the inheritance. But... I have not could to relate them to an abstract type containing these common properties. It's possible to do it using EF?

  • Keeping last record with Grouping

    - by yeahumok
    Hi All I have a report that groups by Company names. I have 2 formula fields (for two of the columns) that pulls the last record from a field. However, i noticed that when i run my reports, it does not show the last record for every group (even though this total line is in the Group Footer). Is there anyway in the formula field, i can specify that the last record must show for every group in my report?
