  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.

  • Set DetailsView as selected row of GridView

    - by Nix
    I am afraid this is a brain fart question. But I have searched around and have not been able to find the answer. I am creating a GridView/DetailsView page. I have a grid that displays a bunch of rows, when a row is selected it uses a DetailsView to allow for Insert/Update. My question is what is the best way to link these? I do not want to reach out to the web service again, all the data i need is in the selected grid view row. I basically have 2 separate data sources that share the same "DataObjectTypeName", the first data source retrieves the data, and the other to do the CRUD. What is the best way to transfer the Selected Grid View row to the Details View? Am I going to have to manualy handle the Insert/Update events and call the data source myself? <asp:GridView ID="gvDetails" runat="server" DataKeyNames="ID, Code" DataSourceID="odsSearchData" > <Columns> <asp:BoundField DataField="RowA" HeaderText="A" SortExpression="RowA" /> <asp:BoundField DataField="RowB" HeaderText="B" SortExpression="RowB" /> <asp:BoundField DataField="RowC" HeaderText="C" SortExpression="RowC" /> ....Code... <asp:DetailsView ID="dvDetails" runat="server" DataKeyNames="ID, Code" DataSourceID="odsCRUD" GridLines="None" DefaultMode="Edit" AutoGenerateRows="false" Visible="false" Width="100%"> <Fields> <asp:BoundField DataField="RowA" HeaderText="A" SortExpression="RowA" /> <asp:BoundField DataField="RowB" HeaderText="B" SortExpression="RowB" /> <asp:BoundField DataField="RowC" HeaderText="C" SortExpression="RowC" /> ...

  • Jquery tooltip plugin qTip doesn't seem to set width properly

    - by ooo
    i have an asp.net mvc site and here is a dynamic tooltip using qTip Here is my code: $('a.showNutritionInfo').each(function() { $(this).qtip({ content: { text: '<img src="../../images/ajax-loader1.gif" alt="" />', style: { width: 450 }, url: '/Tracker/NutritionInfo/' + $(this).attr('id'), method: 'get' } }); }); this works perfectly EXCEPT the width attribute listed above is ignored. No matter what i put in that width attribute, i get the same size width tooltip which is about half of the width that i need. the height is perfectly fine. any ideas? is this a bug in the product ?

  • Is there a way to set a handler function for when a set of events has happened in JavaScript?

    - by allyourcode
    eg I have two concurrent AJAX requests, and I need the result from both to compute a third result. I'm using the Prototype library, so it might look something like this: var r1 = new Ajax.Request(url1, ...); var r2 = new Ajax.Request(url2, ...); function on_both_requests_complete(resp1, resp2) { ... } One way would be to use polling, but I'm thinking there must be a better way.

  • Insert something .after a set of elements if the first in the set has a certain class.

    - by Adripants
    I would like to add a label AFTER a group of radio inputs IF the first has a certain class <label>Has the strategy and all of it's relevant background documents been uploaded</label> <label for="Radio1"><input type="radio" name="uploaded" class="required cat1" id="Radio1">Yes</label> <label for="Radio2"><input type="radio" name="uploaded" id="Radio2">No</label> Radio1 has the class, but I'd like to insert a label after the last (in this case Radio2) I thought I could use this: $('input[type="radio"].cat1').siblings('input:last').after('<label>Hi!</label>'); But it doesn't work.

    I have a table Course and every Course has many Resources. Course ========== course_id Resource ========== course_id number I want something like a seperate autoincrement for each course_id. Or, in other words, I want to auto-enumerate the resources for a given course. For example, the resource table could look something like: course_id | number ================== 1 | 1 1 | 2 2 | 1 1 | 3 1 | 4 2 | 2 2 | 3 and so on. I want to do this in SQL, using IBM DB2.

  • Rails 3 namespacing requires model to be defined twice?

    - by RSG
    I'm pulling my hair out trying to understand namespacing in Rails 3. I've tried following a few different tutorials, and the only way I can get my models to work is if I define my model in both the base directory and my namespace directory. If I only define the model in the namespace directory it expects it to define both Model and Namespace::Model, as below: LoadError (Expected .../app/models/plugins/chat.rb to define Chat): or LoadError (Expected .../app/models/plugins/chat.rb to define Plugins::Chat): I'm sure I'm missing something obvious, but I could really use a pointer in the right direction. Here are the relevant excerpts. /models/plugins/chat.rb class Plugins::Chat include ActiveModel::Validations include ActiveModel::Conversion extend ActiveModel::Naming ... end /controllers/plugins/chats_controller.rb class Plugins::ChatsController < Plugins::ApplicationController load_and_authorize_resource ... end /config/routes.rb namespace :plugins do resources :chats end /config/application.rb config.autoload_paths += Dir["#{config.root}/app/models/**/"]

  • Can HTML checkboxes be set to readonly?

    - by Electrons_Ahoy
    I thought they could be, but as I'm not putting my money where my mouth was (so to speak) setting the readonly attribute doesn't actually seem to do anything. I'd rather not use Disabled, since I want the checked check boxes to be submitted with the rest of the form, I just don't want the client to be able to change them under certain circumstances.

  • How Can I Set Up a "Where" Statement with a PHP Array

    - by Ryan
    Am I able to apply "where" statements to PHP arrays, similar to how I would be able to apply a "where" statement to a MySQL query? For example, suppose I have the following array: $recordset = array( array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 1, 'clicks' => 123, 'users' => 4), array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 2, 'clicks' => 134, 'users' => 5), array('host' => 1, 'country' => 'fr', 'year' => 2010, 'month' => 3, 'clicks' => 341, 'users' => 2), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 1, 'clicks' => 113, 'users' => 4), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 2, 'clicks' => 234, 'users' => 5), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 3, 'clicks' => 421, 'users' => 2), array('host' => 1, 'country' => 'es', 'year' => 2010, 'month' => 4, 'clicks' => 22, 'users' => 3), array('host' => 2, 'country' => 'es', 'year' => 2010, 'month' => 1, 'clicks' => 111, 'users' => 2), array('host' => 2, 'country' => 'es', 'year' => 2010, 'month' => 2, 'clicks' => 2, 'users' => 4), array('host' => 3, 'country' => 'es', 'year' => 2010, 'month' => 3, 'clicks' => 34, 'users' => 2), array('host' => 3, 'country' => 'es', 'year' => 2010, 'month' => 4, 'clicks' => 1, 'users' => 1),); How can I limit the output to only show the keys and values related to 'host' 1 and 'country' fr? Any help would be great.

  • Inputs inside ListView doesn't change values from old to recently set on ItemUpdating event

    - by Tema
    Hi, I would appreciate if someone help me to understand this situation. I do not know why but when i edit selected ListView item (containing few TextBoxes) and then press Update button in the ItemUpdating event i always get old values instead of those which were typed recently. Why? I do not use Page_Load event so i do not need check on PostBack I try to get value before i bind data from DB to ListView, so it can't override recently typed values I tried to get TextBoxes values in different Event handlers - ItemCommand, ItemUpdating, ItemDataBound - result si always the same Collection NewValues and OldValues are always empty (i think this is because i don't use SqlDataSource control) The only one way i can get new values - is to check Request, but in this case i can't use control validators ... so probably it is bad idea to work with only request. This is the code of ItemUpdating method: ListViewItem editItem = AdminUsersListView.EditItem; Guid userId = new Guid((editItem.FindControl("UserId") as HiddenField).Value); Hashtable dataUpdate = new Hashtable { { "UserName", Request[ (editItem.FindControl("UserNameNew") as TextBox).UniqueID ] }, { "Email", Request[ (editItem.FindControl("Email") as TextBox).UniqueID ] }, { "IsApproved", Request[ (editItem.FindControl("IsApproved") as CheckBox).UniqueID ] == "on" }, { "IsLockedOut", Request[ (editItem.FindControl("IsLockedOut") as CheckBox).UniqueID ] == "on" } }; var x1 = dataUpdate["UserName"]; // this is corrent new value from Request var x2 = (editItem.FindControl("UserNameNew") as TextBox).Text; // this is WRONG! OLD! value from TextBox ... Why??? using (Entities entities = new Entities()) { aspnet_Membership membershipItem = entities.aspnet_Membership.Where(MBS => MBS.UserId == userId).FirstOrDefault(); membershipItem.Email = dataUpdate["Email"].ToString(); membershipItem.LoweredEmail = membershipItem.Email.ToLower(); membershipItem.IsApproved = Convert.ToBoolean(dataUpdate["IsApproved"]); membershipItem.IsLockedOut = Convert.ToBoolean(dataUpdate["IsLockedOut"]); entities.SaveChanges(); aspnet_Users userItem = entities.aspnet_Users.Where(USR => USR.UserId == userId).FirstOrDefault(); userItem.UserName = dataUpdate["UserName"].ToString(); userItem.LoweredUserName = userItem.UserName.ToLower(); entities.SaveChanges(); } AdminUsersListView.EditIndex = -1; AdminUsersListView.DataSource = _getDataList(); AdminUsersListView.DataBind(); Thanks, Art

  • calling a function from a set of overloads depending on the dynamic type of an object

    - by Jasper
    I feel like the answer to this question is really simple, but I really am having trouble finding it. So here goes: Suppose you have the following classes: class Base; class Child : public Base; class Displayer { public: Displayer(Base* element); Displayer(Child* element); } Additionally, I have a Base* object which might point to either an instance of the class Base or an instance of the class Child. Now I want to create a Displayer based on the element pointed to by object, however, I want to pick the right version of the constructor. As I currently have it, this would accomplish just that (I am being a bit fuzzy with my C++ here, but I think this the clearest way) object->createDisplayer(); virtual void Base::createDisplayer() { new Displayer(this); } virtual void Child::createDisplayer() { new Displayer(this); } This works, however, there is a problem with this: Base and Child are part of the application system, while Displayer is part of the GUI system. I want to build the GUI system independently of the Application system, so that it is easy to replace the GUI. This means that Base and Child should not know about Displayer. However, I do not know how I can achieve this without letting the Application classes know about the GUI. Am I missing something very obvious or am I trying something that is not possible?

  • can not find out if the div element is already set in body in chrome extension

    - by alpham8
    in my chrome extension I got an div, which I will add to the body of the current tab. I am listening to chrome.tabs.onUpdated. If this event is called, I execute a script inside content_scripts. In this function there I´ll wait till the document is ready with jQuery $(document).ready(...). I try to access $("#div").length and sometimes it returns 1 and sometimes 0. It should added to the body, if it´s not already there. For some strange reasons, the onUpdated event is called twice on each page reload. Actually I found no way to check safely if the div was already added.
