  • Perform Grouping of Resultset in Code

    - by NinjaBomb
    Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

  • .NET Thank you/confirmation page best practise

    - by sooty
    Hi, whats the best practise for implementing a confirmation page in .Net? I've used response.redirect("Thankyou.aspx") a lot in the past I've also used something like this for hiding form controls and outputting a message: outResult.Attributes.Remove("style") outResult.Attributes.Add("style", "display:block;") outEntry.Attributes.Remove("style") outEntry.Attributes.Add("style", "display:none;") For the above you have to consider post backs that may occur if the user click refresh though. Does anybody have a better option? thanks!

  • How to pre-check checkboxes in formtastic

    - by trustfundbaby
    I have a form I'm trying to set up ... Users can have many posts, and each post can have many people watching it. The Watch model is set up polymorphically as 'watchable' so it can apply to different types of models. It has a user_id, watchable_id, watchable_type and timestamps as attributes/fields. This is soley so that when people comment on a post, users watching the post can get an email about it. What I'm trying to do is show the user a list of users that they can tag on each post, which is not problem. This is what I'm using right now http://pastie.org/940421 The problem with this, is that when you go to edit an update/post ... all the checkboxes are prechecked ... I want it to pre-check only users who are currently watching the post.

  • how to wrap a function that only takes individual elements to make it take a list

    - by stevejb
    Hello, Say I have a function handed to me that I cannot change and must use as is. This function takes several objects in the form of oldFunction( object1, object2, object3, ...) where ... are other arguments. I want to write a wrapper to take a list of objects. My idea was this. sjb.ListWrapper <- function(myList,...) { lLen <- length(myList) myStr <- "" for( i in 1:lLen) { myStr <- paste(myStr, "myList[[", i , "]],",sep="") } myCode <- paste("oldFunction(", myStr, "...)") eval({myCode}) } However, the issue is that I want to use this from Sweave and I need the output of oldFunction to be printed. What is the right way to do this? Thanks.

  • Reducing time in C# Forms Control.set_Text(string) function

    - by awshepard
    Hoping for a quick answer (which SO seems to be pretty good for)... I just ran a performance analysis with VS2010 on my app, and it turns out that I'm spending about 20% of my time in the Control.set_Text(string) function, as I'm updating labels in quite a few places in my app. The window has a timer object (Forms timer, not Threading timer) that has a timer1_Tick callback, which updates one label every tick (to give a stop-watch sort of effect), and updates about 15 labels once each second. Does anyone have quick suggestions for how to reduce the amount of time spent updating text on a form, other than increasing the update interval? Are there other structures or functions I should be using?

  • ruby on rails: How do I access variable data in a url parameter passed to a model?

    - by bandhunt
    I have a variable called "account_type" passed from a rails form and need to access the value in the corresponding model. I can check if :account_type exists as a symbol, but where does the stored data come into play? Is there something I need to do in the controller? This code gives an undefined method 'account_type' error. validates_format_of :name, :with => /^[a-z0-9_]+$/i, :on => :create if account_type == 2 If I use a symbol then it doesn't give an error, but a symbol will never equal 2 validates_format_of :name, :with => /^[a-z0-9_]+$/i, :on => :create if :account_type == 2 It's confusing that you can validate the format of a symbol (like :name above) when :name only seems to be a reference with nothing stored in it. Thanks!

  • Workaround for richfaces combobox hotkey bug

    - by John
    Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

  • restful way for deleting a bunch of items

    - by keisimone
    In wiki article for REST it is indicated that if you use http://example.com/resources DELETE, that means you are deleting the entire collection. If you use http://example.com/resources/7HOU57Y DELETE, that means you are deleting that element. I am doing a WEBSITE, note NOT WEB SERVICE. I have a list that has 1 checkbox for each item on the list. Once i select multiple items for deletion, i will allow users to press a button called DELETE SELECTION. If user presses the button, a js dialog box will popup asking user to confirm the deletion. if user confirms, all the items are deleted. So how should i cater for deleting multiple items in a RESTFUL way? NOTE, currently for DELETE in a webpage, what i do is i use FORM tag with POST as action but include a _method with the value DELETE since this is what was indicated by others in SO on how to do RESTful delete for webpage.

  • Is this more suited for key value storage or a tree?

    - by JC
    I'm trying to figure out the best way to represent some data. It basically follows the form Manufacturer.Product.Attribute = Value. Something like: Acme.*.MinimumPrice = 100 Acme.ProductA.MinimumPrice = 50 Acme.ProductB.MinimumPrice = 60 Acme.ProductC.DefaultColor = Blue So the minimum price across all Acme products is 100 except in the case of product A and B. I want to store this data in C# and have some function where GetValue("Acme.ProductC.MinimumPrice") returns 100 but GetValue("Acme.ProductA.MinimumPrice") return 50. I'm not sure how to best represent the data. Is there a clean way to code this in C#?

  • Design Pattern for Server Emulator

    - by adisembiring
    I wanna build server socket emulator, but I want implement some design pattern there. I will described my case study that I have simplified like these: My Server Socket will always listen client socket. While some request message come from the client socket, the server emulator will response the client through the socket. the response is response code. '00' will describe request message processed successfully, and another response code expect '00' will describe there are some error while processing the message request. IN the server there are some UI, this UI contain check response parameter such as. response code timeout interval While the server want to response the client message, the response code taken from input parameter response form UI check the timeout interval, it will create sleep thread and the interval taken from timeout interval input from UI. I have implement the function, but I create it in one class. I feel it so sucks. Can you suggest me what class / interface that I must create to refactor my code.

  • My site was recently attacked. What do I do?

    - by ChrisH
    This is a first for me. One of the sites I run was recently attacked. Not at all an intelligent attack - pure brute force - hit every page and every non-page with every extension possible. Posted with garbage data to every form and tried to post to some random urls too. All tod, 16000 requests in one hour. What should I do to prevent/alert this kind of behavior? Is there a way to limit the request/hr for a given ip/client? Is there a place I should be reporting the user to? They appear to be from China and did leave what seems like a valid e-mail.

  • Insert string from database into an aspx and have databinding expressions within that text evaluated

    - by Christopher Edwards
    Well, as you can see I want something quick-and-dirty! How can I get a string from a db that has aspx databinding syntax in it and have the databinding expressions evaluated? So I have text such as this stored in the DB:- Hello <%=User.Name %> I haven't seen you since <%=User.LastVisit %> And I want it to be inserted here say:- ... <body> <form id="form1" runat="server"> <div> <asp:FormView ID="FormView1" DataSourceID="DataSource1" runat="server"> <ItemTemplate> <-- insert stuff here! --> ... But with the databinding expressions evaluated. I'd rather not build a full parsing, templating and evaluation engine...

  • Table and column naming conventions when plural and singular forms are odd or the same

    - by Superstringcheese
    In my search I found mostly arguments for whether to use plurality in database naming conventions, and ways to handle it in either case. I have decided I prefer plural table names, so I don't want to argue that. I need to represent an animal's species and genus and so on in a database. The plural and singular form for 'species' are the same, and the plural of 'genus' is 'genera'. I think I can get by with: Table: Genera | Column: Genus But I'm unsure how I should handle: Table: Species | Column: Species If I really wanted to be lazy about this I'd just name them 'species specie' and 'genuses genus', but I would prefer to read them in their correct forms. Any advice would be appreciated.

  • WCF: Proxy open and close - whaaa?

    - by MikeMalter
    I am maintaing a windows form application using WCF and are using net.tcp internally. The lifecycle of our connections is GET/USE/CLOSE. We are having a problem with the application pool crashing with no trace. In looking at netstat, I can see when I come into the application as we have a login service. However, even though we are creating the proxy in a using statement, the connection in netstat does not go away until I physically close the application. Is this right? Should I be doing something diffent on the client to force the connection to close? So if the connection stays open, does it stay open for the duration of the openTimeout setting and then gets torn down? Thanks.

  • CMS common Architecture

    - by Shalan
    Hi there, I know this is a weird question to ask, but I would like to know if there is any documentation/blog-article out there that explains the architecture of a Website content management system? More particularly, I am interested to learn more about how "widgets" are implemented. I can't remember which system it was that I've seen tis one, but in the "Page Layout view" it had the ability to allow the end user to select a widget (thumbnail gallery, contact form, etc) from a list, and drag and drop it onto custom areas of the page. I know that this is not directly a programming question, but please could I seek advice/feedback on this. Thanks!

  • Test if element already has jQuery datepicker

    - by macca1
    I have a form with many input elements. Some are date fields with a jQuery UI datepicker alraedy attached: $("#someElement").mask("9?9/99/9999").datepicker({showOn: 'button', buttonText:'Click here to show calendar', duration: 'fast', buttonImageOnly: true, buttonImage: /images/calicon.gif' }); Then I have a key command bound to this function: function openCalendar() { var selection = document.activeElement; // { Need to test here if datepicker has already been initialized $(selection).datepicker("show"); // } } This works great for elements which already have the datepicker on them. However any other fields will throw a javascript error. I'm wondering the best way to test to see if datepicker has already been initialized on that field.

  • Rails HABTM Scoping to current subdomain

    - by Rabbott
    I have the following associations: class User < ActiveRecord::Base has_and_belongs_to_many :brands, :join_table => 'brands_users' has_and_belongs_to_many :companies, :join_table => 'companies_users' end class Brand < ActiveRecord::Base belongs_to :company has_and_belongs_to_many :users, :join_table => 'brands_users' end class Company < ActiveRecord::Base has_and_belongs_to_many :users, :join_table => 'companies_users' has_many :brands, :order => :name end While editing a user I am using the checkbox list of brands. So that I can assign users 'access' to brands, the brands that show up are only the brands that belong to the current company (defined by the subdomain [using subdomain_fu]). The problem I am running into is that when using the default HABTM functionality and the checkbox list, upon save, Rails removes ALL user-brand associations, then re-adds just the ones for the form I just submitted.. How do I scope that to only remove associations of brands who belong to the current company, defined in the subdomain?
