  • How to Execute Page_Load() in Page's Base Class?

    - by DaveDev
    I have the following PerformanceFactsheet.aspx.cs page class public partial class PerformanceFactsheet : FactsheetBase { protected void Page_Load(object sender, EventArgs e) { // do stuff with the data extracted in FactsheetBase divPerformance.Controls.Add(this.Data); } } where FactsheetBase is defined as public class FactsheetBase : System.Web.UI.Page { public MyPageData Data { get; set; } protected void Page_Load(object sender, EventArgs e) { // get data that's common to all implementors of FactsheetBase // and store the values in FactsheetBase's properties this.Data = ExtractPageData(Request.QueryString["data"]); } } The problem is that FactsheetBase's Page_Load is not executing. Can anyone tell me what I'm doing wrong? Is there a better way to get the result I'm after? Thanks

  • Is it okay if my ViewModel 'creates' bindable user controls for my View?

    - by j0rd4n
    I have an entry-point View with a tab control. Each tab is going to have a user control embedded within it. Each embedded view inherits from the same base class and will need to be updated as a key field on the entry-point view is updated. I'm thinking the easiest way to design this page is to have the entry-point ViewModel create and expose a collection of the tabbed views so the entry-point View can just bind to the user control elements using a DataTemplate on the tab control. Is it okay for a ViewModel to instantiate and provide UI elements for its View?

  • C# DDD Populate Immutable Objects

    - by Russel
    Hi I have a immutable Customer class in my domain assembly. It contains the following GET properties : id, firstname and lastname. I have a CustomerRepository class in my persistence assembly. In turn, this CustomerRepository class should populate and return a Customer object using a remote web-serivce. My Customer class contains no setter properties and it contains a private constructor. The reason - I dont want the UI developer to get the wrong idea - He should not be able to create or change a Customer object. My question: How do I get my CustomerRepository to populate my Customer object. Reflection? Or should I sacrifice my design and enable a public constructor for constructing the customer object?

    - by zwang
    I have a really hard design problem in my swing application. Generally Speaking, I have a JTable and a JLabel to display. The label is right below the JTable. When the height of these two components doesn't exceed a threshold, then the jtable and label displays as normal. Then height of these two components will increase as the number of records filled in the table increases. When the height of these two components exceeds a threshold, I want there is a scrollbar in the JTable and the height of these two components will be the threshold. Is this design Possible? I have draft to illustate my UI design requirement. But I don't know how to post it in this forum. And any reply are appreciate. Best Regards, Zheng.

  • Silverlight 4 Multithread

    - by DavyMac23
    I'm trying to update my Silverlight 4 UI approx every 1/2 second with new data. I've hooked into a WCF service using net.tcp binding and issuing callbacks from the server. To make sure I get the data from the service as quickly as possible I've started up my proxy on a backround worker inside of my Silverlight App. My question is, how do I get the results from the callback and update the ObservableCollection that is bound to a datagird? I've tried a number of different ways and keep getting the dreaded cross-thread error.

  • NHibernate auditing in disconnected mode

    - by Ciaran
    I'm developing an app with a Silverlight UI, transferring my domain objects over WCF and persisting them via NHibernate. I'm therefore working with NHibernate in a disconnected mode. I'm already using the NHibernate PreUpdate and PreInsert EventListeners to perform some metadata operations (updating Create/Update date, created/updated by etc) and they are working fine. I now have a requirement to perform data logging on some of my domain objects. So I will need to have an audit table that has a before-save and after-save state of certain entities. I had wanted to use the @event.Persister.OldState and @event.Persister.NewState to perform this logging, but because I am in a disconnected scenario (using different Sessions from when data is retrieved to when it is persisted), @event.Persister.OldState is null when I am saving my changes back to the database. How is anyone else doing data logging in a disconnected scenario with NHibernate?

  • How to override the attr_protected?

    - by KandadaBoggu
    I have STI implementation as follows: class Automobile < ActiveRecord::Base end class Car < Automobile end class Truck < Automobile end class User < ActiveRecord::Base has_many :automobiles accepts_nested_attributes_for :automobiles end I am creating a list of automobiles for a user. For each automobile, the UI sets the type field and the properties associated with the automobile.While form submission, the type field is ignored as it is a protected attribute. How do I work around this issue? Is there a declarative way to unprotect a protected attribute?

  • How to write gSOAP server using VC++ (VS2008)?

    - by Falcon
    Hi, I have downloaded gSOAP2.8 from sourceforge. I want to use it for writting a gsoap based server. I need to be able to invoke my C++ code from PHP UI. E.g. My php page would show something like: $res = a + b = ? [Submit] When submit button is clicked I want these parameters to be passed to my c++ function lets say compute_sum() ... and this function should be invoked with these parameters, and the results given back to my php page. I want to write this gsoap based c++ server. Can someone please help me with getting started with it? I need to know: 1] What kind of c++ code it should it be? (Windows console app, or a windows service) 2] How do I launch this server? (Would it need to be a webservice, hosted over something like apache?) Please advise and guide. Regards, Falcon

  • Binding to a List<object> in silverlight problem.

    - by cw
    Hello, Can someone suggest what I am doing wrong? Basically I have a List Items, when an item gets added to the list I am resetting the collection to the viewmodel property. The only way I can get it to work is if I null the member object out before reassigning the binding. Any suggestions on how to go about updating a UI when an item gets added to a List? public List<Item> RegisteredItems { get { return m_vRegisteredItems; } set { m_vRegisteredItems= null; NotifyPropertyChanged("RegisteredItems"); m_vRegisteredItems= value; NotifyPropertyChanged("RegisteredItems"); } }

  • Browser extensions to re-render the page using an updated version of my CSS file, without reloading the page itself

    - by Eduardo León
    I want to learn Web UI design. (I know, I know. Being a programmer puts me at a disadvantage. But I want to try anyway.) Thus, I would like to "debug" my CSS files. Once of the biggest annoyances I have found is that I cannot test a change in my CSS files without reloading the whole page. Sometimes, the page is too big. Sometimes, a lot of elements were brought to the page after lots of clicks, because my pages rely too heavily on AJAX. Sometimes, I just hate hitting Command+R all the time. Is there any extension for any of the major browsers (preferably Safari and/or Chrome) that re-renders the page using an updated version of the CSS file, without reloading the whole page itself?

  • MPMediaickerController memory leak identified by Leaks instrument

    - by Joe
    This is code from Apple's Addmusic example. MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker"); // The media item picker uses the default UI style, so it needs a default-style // status bar to match it visually [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES]; [self presentModalViewController: picker animated: YES]; [picker release]; I'm using this code in my app and the Leaks instrument highlights a leak on the line: [self presentModalViewController: picker animated: YES]; I think that this is because this line retains a reference to picker which cannot be subsequently released. Is there any way around this or is Leaks incorrectly identifying a leak?

  • Code reviews for larger ASP.NET MVC team using TFS

    - by Parrots
    I'm trying to find a good code review workflow for my team. Most questions similar to this on SO revolve around using shelved changes for the review, however I'm curious about how this works for people with larger teams. We usually have 2-3 people working a story (UI person, Domain/Repository person, sometimes DB person). I've recommended the shelf idea but we're all concerned about how to manage that with multiple people working the same feature. How could you share a shelf between multiple programmers at that point? We worry it would be clunky and we might easily have unintended consequences moving to this workflow. Of course moving to shelfs for each feature avoids having 10 or so checkins per feature (as developers need to share code) making seeing the diffs at code review time painful. Has anyone else been able to successfully deal with this? Are there any tools out there people have found useful aside from shelfs in TFS (preferably open-source)?

  • Dragged div change places with destination

    - by Cudos
    Hi. Maybe a bit complex to explain. I have a grid with 9 images 100 x 100 px like this (each number symbolize a picture): 1 2 3 4 5 6 7 8 9 What I want is that the user can drag and drop e.g. 9 over 1 and they change places like this: 9 2 3 4 5 6 7 8 1 Sortables from jquery UI will not work since their solution is using floats. That will "push" all the boxes to the right or left e.g.: 9 1 2 3 4 5 6 7 8 thanks in advance.

  • Using Session State in Public Class in ASP.NET?

    - by davemackey
    I'm trying to move some reusable portions of code into a class. This is working okay except when I attempt to use Session within this class. I get an error: "Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class." My code looks something like this: Public Class webHousing Inherits System.Web.UI.Page Public Sub GetUserInfo() Dim x as String x = 10 Session("x")= x End Sub End Class I've simplified this code significantly - but the basic problem is present - trying to set a session value from within a class. I found the following MSDN article1 but don't believe Public/Shared can be used on Session?

    Hi - I am looking for the best technology to provide customer ways to add our functionality through buttons on their websites. I know this can be done adding button to a body and attaching a click listener but I am stumped at a point where I need to resize my iframe (UI after they click a button) and it cannot be done from internal iframe. I wanted to check how getsatisfaction, invox, zendesk and other companies offer this functionality. is there a quick tip for this? I am just looking for modus operandi and not actual code. Many thanks.

  • mouse tracking on IE

    - by Gotys
    Consider the following snippet: $(document).bind('mousemove', function(e) { $('#someDiv').css({left: e.pageX+'px', top: e.pageY+'px'}); }); This should make #someDiv follow the mouse (tooltip), when the css value for "position" is set to absolute. Works as expected, except when you Zoom IN or OUT in IE7 ( dind't try other version of IE). Then the e.pageX gets completely off. The more you zoom in (using your mousewheel + CTRL), the more off the positioning gets. I've tried to break jQuery's UI demos (sliders) and it seems not even jQuery guys have this figured out. Is there any genius out there who knows how to fix this nasty thing? Thanks in advance!

  • Sqlite + Java: table not updating

    - by Ben L
    I'm using a Java wrapper for SQLite called SQLiteJDBC - this may have some bearing on any answers... I have a table which I've displayed in a GUI, within that UI I have a button for the fields for an individual row of that table. When I save my changes I do this... Statement stmt = connection.createStatement(); stmt.execute("update 'tableName' set 'fieldName'=1 where userid=1"); int updateCount = stmt.getUpdateCount(); My connection is valid, I get no exceptions thrown and getUpdateCount() returns '1' indicating that one row has been updated. However my table is not updated. I've spent the last few hours trying to work out what's going on but I'm not having any luck. Help!!

  • .rdlc reporting bound to Object Data Source in Three layer Application

    - by Saeedouv
    Hi, i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated... just to make things more clear here, assume the following: i have a solution with the follwoing layers, UI Reporting(has NO Employees object) just a reference Business Logic Data Access Layer(Employees--GetEmployees(), all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.

  • Are SqlCipher open cursors a security concern?

    - by user1178479
    I'm using SqlCipher with content providers. Right now, when I want to lock the app I just clear out the cached password. However, the app can continue to work with any open cursors. This means that re-opening the app grants access to the sensitive data. I fix this issue on the surface by redirecting to a login screen if the app doesn't have passwords. However, I'm concerned if there are any security issues with these open cursors or if I should just continue to block UI access and not worry? SqlCipher's docs say that it reads/writes encrypted pages on the fly, as opposed to decrypting the entire DB, this makes me think that open cursors are still secure. The main concern here is that someone loses their phone and then a knowledgeable individual can use these open cursors to extract sensitive data.

  • Bug Tracker - Feature set - Comparison

    - by Blankman
    Hi, I have installed and played around with a few bug tracking apps, and just wanted to get some feedback and features that a typical (or not so typical) bug tracking software has. I want to make sure I am not overlooking a feature that might come in handy. So the biggest idea is around a bug, which is associated with: Bugs - product - product version - component (specific component of the product) - status - priority - assigned to - expected time to finish - time spent on it so far - created by - historical log of bug Forums Wiki I guess the above functionality is common to all, so what exactly differentiates them? Is it simply the UI and filtering/searching that you base a decision on? (I am comparing something like Jira with FogBugz)

  • Command Query Separation validating for retries

    - by Neil Barnwell
    So I'm comfortable with the basic concept of CQS, where you might have a command that writes to one database, and that updates the query database that you read from. However, consider the scenario where you are entering data, and want to prevent duplicates. Using new employee data entry an employee register as an example, working through a pile of application forms to key in the new employees' details: Take top sheet. Key in employee name and unique payroll number to UI. Submit. Put paper in "completed pile". Repeat. How would you now prevent the user from keying in the same payroll number again, say for instance if they get distracted and can't remember whether they've keyed one in already and the "message" hasn't got all the way back to the query db for the user to search?

  • Open source alternative to Sharepoint lists

    - by Thomas
    Sharepoint's lists functionality is powerful. Because I don't want all the other functionality of Sharepoint, I have been looking for an alternative (preferrable open source) without much success. Basically I want to have a platform or web application that: allows us to define custom datatypes (for different kinds of customer products) has the possibility to create views or forms to present to the user for reading, creating or updating the information of the items of a given datatype a ui to setup this configuration is not required but would be nice to have In an ideal scenario there is an API to get the data out afterwards for further processing.

  • iphone threading speed up startup of app

    - by BahaiResearch.com
    I have an app that must get data from the Sqlite database in order to display the first element to the User. I have created a domain object which wraps the DB access and is a thread safe singleton. Is this following strategy optimal to ensure the fastest load given the iPhone's file access and memory management capabilities in threaded apps: 1) In the AppDelegate's FinishedLaunching event the very first thing I do is create the domain singleton within a new thread. This will cause the domain object to go to Sqlite and get the data it needs without locking the UI thread. 2) I then call the standard Window methods to add the View and MakeKeyAndVisible etc. Is there an earlier stage in the AppDelegate where I should fire off the thread that creates the Domain Object and accesses Sqlite?

  • How To Collapse Just One Field in Django Admin?

    - by Apreche
    The django admin allows you to specify fieldsets. You properly structure a tuple that groups different fields together. You can also specify classes for certain groups of fields. One of those classes is collapse, which will hide the field under a collapsable area. This is good for hiding rarely used or advanced fields to keep the UI clean. However, I have a situation where I want to hide just one lonesome field on many different apps. This will be a lot of typing to create a full fieldset specification in every admin.py file just to put one field into the collapsed area. It also creates a difficult maintenance situation because I will have to edit the fieldset every time I edit the associated model. I can easily exclude the field entirely using the exclude option. I want something similar for collapse. Is this possible?
