  • AS3 OOP MVC with PHP

    - by Pepe Sanchez
    Im new to ActionScript and Flex 3... im trying to develop an MVC 100% OOP application with Flex 3 using MXML,AS3 and PHP. M (PHP) V (MXML) C (AS3) The 3 layers i choose for my development. I have 10 AS3 classes that are object related between them and some inherit or implement interfaces. The only problem here is how to interact 100% OOP with my model. In this case my model has to be a PHP Class that needs to be called from AS3 (the controller). For example the AS3 class : Patient have a method called Save: public function Save(data:Array) : void { /* PHP call - model layer */ } I want to create an instance of my PHP Patient Model class that connects to the DB and insert the data array into it. What should i use ? how can i also return a variable to AS3 ? What happen to as3 if there is a cached Exception in PHP ? Thanks in advanced :)

  • UITableView issue when using separate delegate/dataSource

    - by Adam Alexander
    General Description: To start with what works, I have a UITableView which has been placed onto an Xcode-generated view using Interface Builder. The view's File Owner is set to an Xcode-generated subclass of UIViewController. To this subclass I have added working implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: and the Table View's dataSource and delegate are connected to this class via the File Owner in Interface Builder. The above configuration works with no problems. The issue occurs when I want to move this Table View's dataSource and delegate implementations out to a separate class, most likely because there are other controls on the View besides the Table View and I'd like to move the Table View-related code out to its own class. To accomplish this, I try the following: Create a new subclass of UITableViewController in Xcode Move the known-good implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: to the new subclass Drag a Table View Controller to the top level of the existing XIB in InterfaceBuilder, delete the View/TableView that are automatically created for this Table View Controller, then set the Table View Controller's class to match the new subclass Remove the previously-working Table View's existing dataSource and delegate connections and connect them to the new Table View Controller When complete, I do not have a working Table View. I end up with one of three outcomes which can seemingly happen at random: When the Table View loads, I get a runtime error indicating I am sending tableView:cellForRowAtIndexPath: to an object which does not recognize it When the Table View loads, the project breaks into the debugger without error There is no error, but the Table View does not appear With some debugging and having created a basic project just to reproduce this issue, I am usually seeing the 3rd option above (no error but no visible table view). I added some NSLog calls and found that although numberOfSectionsInTableView and numberOfRowsInSection are both getting called, cellForRowAtIndexPath is not. I am convinced I'm missing something really simple and was hoping the answer may be obvious to someone with more experience than I have. If this doesn't turn out to be an easy answer I would be happy to update with some code or a sample project. Thanks for your time! Complete steps to reproduce: Create a new iPhone OS, View-Based Application in Xcode and call it TableTest Open TableTestViewController.xib in Interface Builder and drag a Table View onto the provided view surface. Connect the Table View's dataSource and delegate outlets to File's Owner, which should already represent the TableTestViewController class. Save your changes Back in Xcode, add the following code to TableTestViewController.m: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Returning num sections"); return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"Returning num rows"); return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Trying to return cell"); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = @"Hello"; NSLog(@"Returning cell"); return cell; } Build and Go, and you should see the word Hello appear in the TableView Now to attempt to move this TableView's logic out to a separate class, first create a new file in Xcode, choosing UITableViewController subclass and calling the class TableTestTableViewController Remove the above code snippet from TableTestViewController.m and place it into TableTestTableViewController.m, replacing the default implementation of these three methods with ours. Back in Interface Builder within the same TableTestViewController.xib file, drag a Table View Controller into the main IB window and delete the new Table View object that automatically came with it Set the class for this new Table View Controller to TableTestTableViewController Remove the dataSource and delegate bindings from the existing, previously-working Table View and reconnect the same two bindings to the new Table Test Table View Controller we created. Save changes, Build and Go, and if you're getting the results I'm getting, note the Table View no longer functions properly Solution: With some more troubleshooting and some assistance from the iPhone Developer Forums at https://devforums.apple.com/message/5453, I've documented a solution! The main UIViewController subclass of the project needs an outlet pointing to the UITableViewController instance. To accomplish this, simply add the following to the primary view's header (TableTestViewController.h): #import "TableTestTableViewController.h" and IBOutlet TableTestTableViewController *myTableViewController; Then, in Interface Builder, connect the new outlet from File's Owner to Table Test Table View Controller in the main IB window. No changes are necessary in the UI part of the XIB. Simply having this outlet in place, even though no user code directly uses it, resolves the problem completely. Thanks to those who've helped and credit goes to BaldEagle on the iPhone Developer Forums for finding the solution.

  • How to throw a SqlException(need for mocking)

    - by chobo2
    Hi I am trying to test some exceptions in my project and one of the Exceptions I catch is SQlException. Now It seems that you can't go new SqlException() so I am not sure how I can throw a exception especially without somehow calling the database(and since it is unit tests it is usually advised not to call the database since it is slow). So I am using nunit and moq so I am not sure how to fake this. Edit Based on the answers they seem to all be based on ado.net I am using linq to sql. So that stuff is like behind the scenes. Edit @ Matt Hamilton System.ArgumentException : Type to mock must be an interface or an abstract or non-sealed class. at Moq.Mock`1.CheckParameters() at Moq.Mock`1..ctor(MockBehavior behavior, Object[] args) at Moq.Mock`1..ctor(MockBehavior behavior) at Moq.Mock`1..ctor() Posts to the first line when it tries to mockup var ex = new Mock<System.Data.SqlClient.SqlException>(); ex.SetupGet(e => e.Message).Returns("Exception message");

  • Custom form designer, move/resize controls using WinAPI

    - by jonny
    I have to fix some problems and enchance form designer written long ago for a database project. In Design Panel class code I encountered these lines private void DesignPanel_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { (sender as Control).Capture = false; switch (FMousePosition) { case MousePosition.mpNone: SendMessage((sender as Control).Handle, WM_SYSCOMMAND, 0xF009, 0); break;// Move case MousePosition.mpRightBottom: SendMessage((sender as Control).Handle, WM_SYSCOMMAND, 0xF008, 0); break;//RB case MousePosition.mpLeftBottom: SendMessage((sender as Control).Handle, WM_SYSCOMMAND, 0xF007, 0); // ... here are similar cases ... case MousePosition.mpLeft: SendMessage((sender as Control).Handle, WM_SYSCOMMAND, 0xF001, 0); break;//L } } } FMousePosition indicates whether mouse was over any edge of selected control. What confusing me is these windows messages: it seems there is no documentation on WM_SYSCOMMAND with parameters 0xF001-0xF009 (maybe it starts some kind of 'drag/resize sequence'). Any ideas? If my suggestion is right, then how can I cancel these sequences?

  • WPF Binding Failure performance hit vs Exception

    - by Aran Mulholland
    when we bind to heterogeneous collection of objects, not all objects have the same set of properties. in the output window we get a message like: System.Windows.Data Error: 39 : BindingExpression path error: 'RoundingFactor' property not found on 'object' ''MultiLineTextMarkingScheme' (HashCode=7262386)'. BindingExpression:Path=RoundingFactor;.......... This doesn't appear to be an exception, but we are concerned it has a performance impact. Should we be concerned and create a view model that has all the properties we wish to bind to (and have the properties that dont exist on the underlying element return null) or can we just leave it. This situation often occurs in a grid scenario where there might be large numbers of these binding failures.

  • C# - Repeating a method call using timers

    - by Jeremy Rudd
    In a VSTO add-in I'm developing, I need to execute a method with a specific delay. The tricky part is that the method may take anywhere from 0.1 sec to 1 sec to execute. I'm currently using a System.Timers.Timer like this: private Timer tmrRecalc = new Timer(); // tmrRecalc.Interval = 500 milliseconds private void tmrRecalc_Elapsed(object sender, System.Timers.ElapsedEventArgs e){ // stop the timer, do the task     tmrRecalc.Stop();         Calc.recalcAll();         // restart the timer to repeat after 500 ms     tmrRecalc.Start(); } Which basically starts, raises 1 elapse event after which it is stopped for the arbitrary length task is executed. But the UI thread seems to hang up for 3-5 seconds between each task. Do Timers have a 'warm-up' time to start? Is that why it takes so long for its first (and last) elapse? Which type of timer do I use instead?

  • INetCfgComponent::RaisePropertyUi arguments

    - by Soo Wei Tan
    I'm trying to do some COM interop and attempting to invoke the INetCfgComponent::RaisePropertyUi method. I've gotten to the point where I can enumerate devices and get a valid INetCfgComponent for the adapter that I want to display the UI for. However, I'm a COM newbie (let alone COM interop) so I have no idea what the third argument in RaisePropertyUi() is meant to be. I've tried passing in the INetCfgComponent object that I have, but that just results in a InvalidCastException. MSDN has the following to say about the argument: Pointer to the IUnknown interface. RaisePropertyUi retrieves from IUnknown the interface of the context in which to display a network component's property sheet. RaisePropertyUi uses this interface to restrict the display of the property sheet to the context of a connection.

  • Folder.Bind - "Id is malformed" - Exchange Web Services Managed API

    - by Michael Shimmins
    I'm passing the Folder.Id.UniqueId property of a folder retrieved from a FindFolders query via the query string to another page. On this second page I want to use that UniqueId to bind to the folder to list its mail items: string parentFolderId = Request.QueryString["id"]; ... Folder parentFolder = Folder.Bind(exchangeService, parentFolderId); // do something with parent folder When I run this code it throws an exception telling me the Id is manlformed. I thought maybe it needs to be wrapped in a FolderId object: Folder parentFolder = Folder.Bind(exchangeService, new FolderId(parentFolderId)); Same issue. I've been searching for a while, and have found some suggestions about Base64/UTF8 conversion, but again that did not solve the problem. Anyone know how to bind to a folder with a given unique id?

  • Importing AutoCAD/Solidworks drawings/objects into winforms?

    - by Dinoo
    Has anybody done anything like that? I need to import 3d objects, done in either AutoCAD or Solidworks, and draw them into a windows form. I only need the object to be viewed in 3D and moved around - no manipulation required. I am assuming I will need 2 libraries at least, one for a very simple 3D engine, and one to actually get what I need from the CAD/SW files. Autodesk has a SDK available for developing AutoCAD plugins using .NET, but I am not sure if you can use it the other way around - loading files into the .NET app. Any help, links, and ideas are appreciated.

  • How can you inject an asp.net (mvc2) custom membership provider using Ninject?

    - by AlDev
    OK, so I've been working on this for hours. I've found a couple of posts here, but nothing that actually resolves the problem. So, let me try it again... I have an MVC2 app using Ninject and a custom membership provider. If I try and inject the provider using the ctor, I get an error: 'No parameterless constructor defined for this object.' public class MyMembershipProvider : MembershipProvider { IMyRepository _repository; public MyMembershipProvider(IMyRepository repository) { _repository = repository; } I've also been playing around with factories and Initialize(), but everything is coming up blanks. Any thoughts/examples?

  • C# - Pass by value & Pass by Reference

    - by Lijo
    Hi Team, Could you please explain the following behavior of C# Class. I expect the classResult as "Class Lijo"; but actual value is “Changed”. We’re making a copy of the reference. Though the copy is pointing to the same address, the method receiving the argument cannot change original. Still why the value gets changed ? public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Person p = new Person(); p.Name = "Class Lijo"; Utilityclass.TestMethod(p); string classResult = p.Name; Response.Write(classResult); } } public class Utilityclass { public static void TestMethod(Person k) { k.Name = "Changed"; } } public class Person { private string name; public string Name { get { return name; } set { name = value; } } } Thanks Lijo

  • Is Objective C fast enough for DSP/audio programming

    - by morgancodes
    I've been making some progress with audio programming for iPhone. Now I'm doing some performance tuning, trying to see if I can squeeze more out of this little machine. Running Shark, I see that a significant part of my cpu power (16%) is getting eaten up by objc_msgSend. I understand I can speed this up somewhat by storing pointers to functions (IMP) rather than calling them using [object message] notation. But if I'm going to go through all this trouble, I wonder if I might just be better off using C++. Any thoughts on this?

  • WPF Custom TextBox ContextMenuOpening Problem

    - by Tom Allen
    I've got an issue with a custom control that I've written not firing it's ContextMenuOpening event when I hook it up programatically. The control is basically a wrapper for the standard TextBox: public class MyTextBox : TextBox { public MyTextBox() { this.ContextMenuOpening += new ContextMenuEventHandler(MyTextBox_ContextMenuOpening); } void MyTextBox_ContextMenuOpening(object sender, ContextMenuEventArgs e) { MessageBox.Show("ContextMenuOpening event fired"); } } There's nothing suspect either about the XAML: <local:MyTextBox Height="25" Width="300"/> For some reason though, I can never get the event to fire. I'm trying to intercept the context menu so I can alter it (it's context sensitive) and really am trying to avoid having to hook up the event everywhere the control is used - surely this is possible?

  • Axis/SOAP service styles and interoperability

    - by Thilo
    There are four "styles" of service in Axis. RPC services use the SOAP RPC conventions, and also the SOAP "section 5" encoding. Document services do not use any encoding (so in particular, you won't see multiref object serialization or SOAP-style arrays on the wire) but DO still do XML<-Java databinding. Wrapped services are just like document services, except that rather than binding the entire SOAP body into one big structure, they "unwrap" it into individual parameters. Message services receive and return arbitrary XML in the SOAP Envelope without any type mapping / data binding. If you want to work with the raw XML of the incoming and outgoing SOAP Envelopes, write a message service. So, if I use anything else except the first option(SOAP RPC Section 5), how does this impact interoperability? If someone says they want a SOAP service (including WSDL), does this mean that SOAP RPC conventions are expected? Can the other three styles still be used when the other end is not implemented with Axis?

  • Collision Detection - Java - Rectangle

    - by Trizicus
    I would like to know if this is a good idea that conforms to best practices that does not lead to obscenely confusing code or major performance hit(s): Make my own Collision detection class that extends Rectangle class. Then when instantiating that object doing something such as Collision col = new Rectangle(); <- Should I do that or is that something that should be avoided? I am aware that I 'can' but should I? I want to extend Rectangle class because of the contains() and intersects() methods; should I be doing that or should I be doing something else for 2D collision detection in Java?

  • How to follow user location with MapKit

    - by Bloudermilk
    I'm using MapKit to display the user's location relative to pins around them. I'd like to be able to mimic the functionality that Maps provides via the crosshair button in the lower left-hand corner of the screen. I'm already aware that MapKit provides a CLLocation object with the user's location via MKUserLocation, I just wanted to seek advice on how I should keep focus on that location. My initial inclination was to use an NSTimer to center the map on that coordinate every 500ms or so. Is there a better way to do this? Is there something built in to MapKit that I'm missing that will accomplish this? Thanks so much, Brendan
