  • Spring.NET & Immediacy CMS (or how to inject to server side controls without using PageHandlerFactor

    - by Simon Rice
    Is there any way to inject dependencies into an Immediacy CMS control using Spring.NET, ideally without having to use to ContextRegistry when initialising the control? Update, with my own answer The issue here is that Immediacy already has a handler defined in web.config that deals with all aspx pages, & so it's not possible add an entry for Spring.NET's PageHandlerFactory in web.config as per a normal webforms app. That rules out making the control implement ISupportsWebDependencyInjection. Furthermore, most of Immediacy's generated pages are aspx pages that don't physically exist on the drive. I have changed the title of the question to reflect this. What I have done to get Dependency Injection working is: Add the usual entries to web.config for Spring.NET as outlined in the documentation, except for the adding the entry to the <httpHandlers> section. In this case I've got my object definitions in Spring.config. Create the following abstract base class that will deal with all of the Dependency Injection work: DIControl.cs public abstract class DIControl : ImmediacyControl { protected virtual string DIName { get { return this.GetType().Name; } } protected override void OnInit(EventArgs e) { if (ContextRegistry.GetContext().GetObject(DIName, this.GetType()) != null) ContextRegistry.GetContext().ConfigureObject(this, DIName); base.OnInit(e); } } For non-immediacy controls, you can make this server side control inherit from Control or whatever subclass of that you like. For any control with which you wish to use with Spring.NET's Inversion of Control container, define it to inherit from DIControl & add the relelvant entry to Spring.config, for example: SampleControl.cs public class SampleControl : DIControl, INamingContainer { public string Text { get; set; } protected string InjectedText { get; set; } public SampleControl() : base() { Text = "Hello world"; } protected override void RenderContents(HtmlTextWriter output) { output.Write(string.Format("{0} {1}", Text, InjectedText)); } } Spring.config <objects xmlns="http://www.springframework.net"> <object id="SampleControl" type="MyProject.SampleControl, MyAssembly"> <property name="InjectedText" value="from Spring.NET" /> </object> </objects> You can optionally override DIName if you wish to name your entry in Spring.config differently from the name of your class. Provided everything's done correctly, you will have the control writing out "Hello world from Spring.NET!" when used in a page. This solution uses Spring.NET's ContextRegistry from within the control, but I would be surprised if there's no way around that for Immediacy at least since the page objects themselves aren't accessible. However, can this be improved at all from a Spring.NET perspective? Is there maybe an Immediacy plugin that already does this that I'm completely unaware of? Or is there an approach that does this in a more elegant way? I'm open to suggestions.

  • Where would you document standardized complex data that is passed between many objects and methods?

    - by Eli
    Hi All, I often find myself with fairly complex data that represents something that my objects will be working on. For example, in a task-list app, several objects might work with an array of tasks, each of which has attributes, temporal expressions, sub tasks and sub sub tasks, etc. One object will collect data from web forms, standardize it into a format consumable by the class that will save them to the database, another object will pull them from the database, put them in the standard format and pass them to the display object, or the update object, etc. The data itself can become a fairly complex series of arrays and sub arrays, representing a 'task' or list of tasks. For example, the below might be one entry in a task list, in the format that is consumable by the various objects that will work on it. Normally, I just document this in a file somewhere with an example. However, I am thinking about the best way to add it to something like PHPDoc, or another standard doc system. Where would you document your consumable data formats that are for many or all of the objects / methods in your app? Array ( [Meta] => Array ( //etc. ) [Sched] => Array ( [SchedID] => 32 [OwnerID] => 2 [StatusID] => 1 [DateFirstTask] => 2011-02-28 [DateLastTask] => [MarginMonths] => 3 ) [TemporalExpressions] => Array ( [0] => Array ( [type] => dw [TemporalExpID] => 3 [ord] => 2 [day] => 6 [month] => 4 ) [1] => Array ( [type] => dm [TemporalExpID] => 32 [day] => 28 [month] => 2 ) ) [Task] => Array ( [SchedTaskID] => 32 [SchedID] => 32 [OwnerID] => 2 [UserID] => 5 [ClientID] => 9 [Title] => Close Prior Year [Body] => [DueTime] => ) [SubTasks] => Array ( [101] => Array ( [SchedSubTaskID] => 101 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Review Profit and Loss by Class [Body] => [DueDiff] => 0 ) [102] => Array ( [SchedSubTaskID] => 102 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Review Balance Sheet [Body] => [DueDiff] => 0 ) [103] => Array ( [SchedSubTaskID] => 103 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Review Current Year for Prior Year Expenses to Accrue [Body] => Look at Journal Entries that are templates as well. [DueDiff] => 0 ) [104] => Array ( [SchedSubTaskID] => 104 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Review Prior Year Membership from 11/1 - 12/31 to Accrue to Current Year [Body] => [DueDiff] => 0 ) [105] => Array ( [SchedSubTaskID] => 105 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Enter Vacation Accrual [Body] => [DueDiff] => 0 ) [106] => Array ( [SchedSubTaskID] => 106 [ParentST] => 105 [RootT] => 32 [UserID] => 2 [Title] => Email Peter requesting Vacation Status of Employees at Year End [Body] => We need Employee Name, Rate and Days of Vacation left to use. We also need to know if the employee used any of the prior year's vacation. [DueDiff] => 43 ) [107] => Array ( [SchedSubTaskID] => 107 [ParentST] => [RootT] => 32 [UserID] => 2 [Title] => Grants Receivable at Year End [Body] => [DueDiff] => 0 ) [108] => Array ( [SchedSubTaskID] => 108 [ParentST] => 107 [RootT] => 32 [UserID] => 2 [Title] => Email Peter Requesting if there were and Grants Receivable at year end [Body] => [DueDiff] => 43 ) ) )

  • Discovering a functional algorithm from a mutable one

    - by Garrett Rowe
    This isn't necessarily a Scala question, it's a design question that has to do with avoiding mutable state, functional thinking and that sort. It just happens that I'm using Scala. Given this set of requirements: Input comes from an essentially infinite stream of random numbers between 1 and 10 Final output is either SUCCEED or FAIL There can be multiple objects 'listening' to the stream at any particular time, and they can begin listening at different times so they all may have a different concept of the 'first' number; therefore listeners to the stream need to be decoupled from the stream itself. Pseudocode: if (first number == 1) SUCCEED else if (first number >= 9) FAIL else { first = first number rest = rest of stream for each (n in rest) { if (n == 1) FAIL else if (n == first) SUCCEED else continue } } Here is a possible mutable implementation: sealed trait Result case object Fail extends Result case object Succeed extends Result case object NoResult extends Result class StreamListener { private var target: Option[Int] = None def evaluate(n: Int): Result = target match { case None => if (n == 1) Succeed else if (n >= 9) Fail else { target = Some(n) NoResult } case Some(t) => if (n == t) Succeed else if (n == 1) Fail else NoResult } } This will work but smells to me. StreamListener.evaluate is not referentially transparent. And the use of the NoResult token just doesn't feel right. It does have the advantage though of being clear and easy to use/code. Besides there has to be a functional solution to this right? I've come up with 2 other possible options: Having evaluate return a (possibly new) StreamListener, but this means I would have to make Result a subtype of StreamListener which doesn't feel right. Letting evaluate take a Stream[Int] as a parameter and letting the StreamListener be in charge of consuming as much of the Stream as it needs to determine failure or success. The problem I see with this approach is that the class that registers the listeners should query each listener after each number is generated and take appropriate action immediately upon failure or success. With this approach, I don't see how that could happen since each listener is forcing evaluation of the Stream until it completes evaluation. There is no concept here of a single number generation. Is there any standard scala/fp idiom I'm overlooking here?

  • When should I use static methods in a class and what are the benefits?

    - by NAVEED
    I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

  • Why is this c# snippet legal?

    - by Sir Psycho
    Silly question, but why does the following line compile? int[] i = new int[] {1,}; As you can see, I haven't entered in the second element and left a comma there. Still compiles even though you would expect it not to.

  • How do I store multiple copies of the same field in Django?

    - by Alistair
    I'm storing OLAC metadata which describes linguistic resources. Many of the elements of the metadata are repeatable -- for example, a resource can have two languages, three authors and four dates associated with it. Is there any way of storing this in one model? It seems like overkill to define a model for each repeatable metadata element -- especially since the models will only have one field: it's value.

  • NotifyIcon behaviour on Windows 7 with MouseClick, MouseDoubleClick events

    - by binball
    I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :)

  • shopping cart to email

    - by marc-andre menard
    I use simplecartjs to make a shopping cart on my website where you can select element and send it to your cart... next step, will be the checkout process, but for business reason, no checkout process will append, and a simple form with name and email and date for order pickup will be ask. Now the order must be send to an email address (at the company) that will fullfill the order. The question : how to send the content of the cart to an email body or as attachement ?

  • What is the best way to limit text input entry to numbers, lowercase letters, and certain symbols?

    - by Adam Maras
    Without using jQuery, what is the best way to limit text entry of a textbox to numbers, lowercase letters and a given set of symbols (for example - and _)? If the user enters an uppercase letter, I would like it to be automatically converted to a lowercase letter, and if the user enters a symbol not within the given set, I would like to be able to instantly show a validation error (show some element adjacent to or below the text box). What's the cleanest cross-browser way of doing this without the aid of jQuery?

  • Bound DataGridView not updating data source

    - by Max Yaffe
    I'm trying to bind a table of structures to a DataGridView. Loading and viewing the table is working fine but I can't edit a value and get it stored back into the table. Here's what I'm doing. I have a "primitive" data type, Real defined by public struct MyReal:IMyPrimative { public Double m_Real; //... public MyReal(String val) { m_Real = default(Double); Init(val); } //... } It gets used in a structure: public struct MyReal_Record : IMyRecord { public MyReal Freq { get; set;} MyReal_Record(String[] vals) { Init(vals); } } And the structure is used to define a table using a generic Binding List public class MyTable<S> : BindingList<S> where S: struct, IMyRecord { public Type typeofS; public MyTable() { typeofS = typeof(S); // ... } This table is used as a binding source for a grid, dynamically. private void miLoadFile_Click(object sender, EventArgs e) { MyModel.Table<Real_Record> RTable = new MyModel.Table<Real_Record>(); //... Table initialized here //set up grid with virtual mode dataGridView1.DataSource = RTable; } All of this works fine and I can create RTable, initialize it and display it in a grid. The grid allows editing and has events set for CellParsing and CellFormatting which look like: private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (e.DesiredType != typeof(String)) return; e.Value = e.Value.ToString(); } private void dataGridView1_CellParsing(object sender, DataGridViewCellParsingEventArgs e) { if (e.DesiredType != typeof(MyReal)) return; e.Value = new MyReal(e.Value.ToString()); e.ParsingApplied = true; this.dataGridView1.UpdateCellValue(e.ColumnIndex, e.RowIndex); } When I edit a value in a cell, I can change the text. On leaving the cell, CellParsing fires and the event handler is called. Everything seems to be correct going into the CellParsing handler. e.DesiredType is MyReal. e.Value is a string with the new value. After the new MyReal is created from the string, e.Value is set correctly. RowIndex and ColumnIndex are correct. ReadOnly is set false. However, when I leave the cell, the system restores the original value to the cell. I thought the UpdateCellValue would replace the value in the dataSource but I seem to be missing something. What did I miss? Thanks, Max

  • How to deal with databases for websites written in Java, more specifically Wicket?

    - by John
    Hi there. I'm new to website development using Java but I've got started with Wicket and make a little website. I'd like to expand on what I've already made (a website with a form, labels and links) and implement database connectivity. I've looked at a couple of examples, in example Mystic Paste, and I see that they're using Hibernate and Spring. I've never touched Hibernate or Spring before and to be honest the heavy use of annotations scare me a little bit as I haven't really made use of them before, with the exception of supressing warnings and overriding. At this point I have one Connection object which I set up in the WebApplication class upon initialization. I then retrieve this connection object whenever I need to perform queries. I don't know if this is a bad approach or not for a production web application. All help is greatly appreciated.

  • JQuery: can I submit values from inputs that aren't in a form?

    - by Alvaro
    Simple as that: I have some inputs that are rendered inside another form element, but I want to submit then individually. I tried "serializing" the div that contains them, but it didn't work. Is there an easy way to do this? My code: var form = $("#my_div"); var get_data = $(form).serialize(); /* Get #my_div inputs value */ $.get(self.url_form_rendering, get_data, function (data){ /* handle server response */ }) Serialize returns "", any ideas that don't involve redesigning the layout to avoid form nesting?

  • What exactly is REST architecture and how is it implemented in Rails?

    - by Jagira
    This is what I think of REST architecture. For every resource, there is an unique URI. We can manipulate that object using its URI and HTTP actions [POST, GET, PUT and DELETE]. The HTTP request transfers the representation of the state of that object. In all the texts I have read, REST is explained in a weird and confusing manner. One more thing, RESTFUL implementation in rails produces different urls for different purposes. Like /teams - for 'index' method... /teams/new - for 'new' method and so on. Ain't this moving away from rest, which defines that each resource has one unique URI???

  • C array initialization.

    - by chrisdew
    Why does static char *opcode_str[] = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; work, but static char **opcode_str = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; fails with SEGV when opcode_str[0] is printf'd? I think it's because the second listing has not allocated memory for the five element array of pointers, but I need a more comprehensive explanation. All the best, Chris.

  • Guidelines of when to use locking

    - by miguel
    I would like to know if there are any guidelineswhich a developer should follow as to when (and where) to place locks. For instance: I understand that code such as this should be locked, to avoid the possibility of another thread changing the value of SomeHeapValue unexpectedly. class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = inputValue_; } } My question is, however, how deep does one go with the locking? For instance, if we have this code: class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = GetSomeHeapValue(); } } Should we lock in the DoSummat(...) method, or should we lock in the GetSomeHeapValue() method? Are there any guidelines that you all keep in mind when strcturing multi-threaded code?
