• Spring Security - is Role and ACL security overkill?

  - by HDave

  I have a 3 tier application that requires security authorizations be placed on various domain objects. Whether I use Spring's ACL implementation or roll my own, it seems to me that ACL based security can only be used to authorize (service) methods and cannot be used to authorize URL or web service invocations. I think this because how could a web service call check the ACL before it has hydrated the XML payload? Also, all the examples for web access security in the Spring documentation are securing URL's based on Role. Is it typical to use Spring's roles to secure web presentation and web service calls, while at the same time using ACL's to secure the business methods? Is this overkill?

• iPhone to iPhone communication

  - by Dan

  Hi, I have been looking into communication methods between two iPhone devices and as I understand it there are two main methods to do this: Bluetooth and WiFi. However I wanted to know if anyone knows of any other way of sharing information between two iPhones? If I were in an area with no WiFi or mobile signal, and couldn't use Bluetooth for whatever reason, is there anything that could be done to broadcast data from one iPhone to another? I'm sure its a bit of a silly question, but if you don't ask, you don't get; and if someone knows of anything I might be able to look into with regards to this, I would be very appreciative. Thanks, Dan

• Identify which AlertDialog triggered onClick(DialogInterface dialog, int which)

  - by Kurian

  I'm creating a dialog as follows: @Override protected Dialog onCreateDialog(int id) { switch (id) { case DIALOG_1: return new AlertDialog.Builder(this) .setTitle(R.string.s_dlg1) .setPositiveButton(android.R.string.ok, this) .create(); case DIALOG_2: ... ... } return null; } @Override public void onClick(DialogInterface dialog, int whichButton) { if (dialog == ???) { ... } else if (dialog == ???){ ... } } How do I identify which dialog triggered the onClick method? I can't declare the interface methods as in-line when creating the dialog because I want to access variables in my class. Every other interface passes some sort of id to its methods to identify which object called the method, but I can't seem to do anything with 'DialogInterface dialog'.

• A definitive guide to Url Encoding in ASP .NET

  - by cbp

  I am starting to realise that there are about a bazillion different methods for encoding urls in .NET. I keep finding new ones. They all work slightly differently, but they all have essentially the same summary comments. Does anyone have a definitive matrix that shows the exact differences between the following methods: HttpUtility.UrlEncode HttpUtility.UrlPathEncode Server.UrlEncode Uri.EscapeUriString Uri.EscapeDataString ... are they any more? Also it would be good to match these up with use-cases e.g.: Urls in href attributes of a tags Urls to be displayed to the user in HTML Urls as querystring values (i.e. to be sent in GET requests) Urls to be sent in POST requests etc

• How do you set a variable value from another form?

  - by flavour404

  Hi, c# .Net 3.5 visual studio 2008, windows xp I have a main form in a project, given a specific set of circumstances another form is instantiated and displayed to the user: Form frmT = new frmTargetFolder(expName, this); frmT.Show(); As you can see, I am passing a reference to the new form from the current one. My question is, what do I have to do to a method so that it is exposed to the new form, the same for a variable? I have tried defining the functions as public, but I can't seem to access them, also I have written a Get and Set method for a variable, again how do I expose these functions and methods to other forms? public void hit() { MessageBox.Show("hit it"); } bool setOverRide { get { return OverRide; } set { OverRide = value; } } The main form is called frmDataXfer and the form, form which I am trying to call the functions and methods of frmDataXfer is called frmTargetFolder, an instance of which is created in the frmDataXfer and referenced as frmT. Thanks, R.

• C# can I lock a method parameter?

  - by 5YrsLaterDBA

  We have a class variable ArrayList binaryScanData in a class. In all methods having access to it, we put lock(binaryScanData) on it because it is shared. Now we want to move one of those methods out to another util class to make it a static method. We will pass that binaryScanData into the method like this: public static void convertAndSaveRawData(ref MemoryStream output, ref ArrayList binaryScanData) Our questions are followed: how can we sychoronize that binaryScanData? can we do the same as it is originally? ref is necessary? It will only be read in that convertAndSaveRawData method.

• Linux, static lib referring to other static lib within an executable

  - by andras

  Hello, I am creating an application, which consists of two static libs and an executable. Let's call the two static libs: libusefulclass.a libcore.a And the application: myapp libcore instantiates and uses the class defined in libusefulclass (let's call it UsefulClass) Now, if I link the application in the following way: g++ -m64 -Wl,-rpath,/usr/local/Trolltech/Qt-4.5.4/lib -o myapp src1.o src2.o srcN.o -lusefulclass -lcore The linker complains about the methods in libusefulclass not being found: undefined reference to `UsefulClass::foo()' etc. I found a workaround for this: If UsefulClass is also instantiated within the source files of the executable itself, the application is linked without any problems. My question is: is there a more clean way to make libcore refer to methods defined in libusefulclass, or static libs just cannot be linked against eachother? TIA P.S.: In case that matters: the application is being developed in C++ using Qt, but I feel this is not a Qt problem, but a library problem in general.

• How to disable Events for a while in Javascript or jQuery

  - by Tarik

  Hello, I am wondering if you guys know different approach to disable an event for a while. Let me elaborate this more : Lets say I have a div or button which has a subscriber to its onclick event. To prevent the double click when the the methods are doing some ajax things, these are the some of the ways we can do : Disable the button till the method finishes its job Unbind till the methods finishes its job and then bind it again. Use some kind of flagging system like boolean so it will prevent method from working more than once. So is there any other ways, maybe some javascript tricks or jQuery tricks which is more efficient and better practice. Thanks in advance.

• MVC2: Best Way to Intercept ViewRequest and Alter ActionResult

  - by Matthew

  I'm building an ASP.NET MVC2 Web Application that requires some sophisticated authentication and business logic that cannot be achieved using the out of the box forms authentication. I'm new to MVC so bear with me... My plan was to mark all restricted View methods with one or more custom attributes (that contain additional data). The controller would then override the OnActionExecuting method to intercept requests, analyze the target view's attributes, and do a variety of different things, including re-routing the user to different places. I have the interception and attribute analysis working, but the redirection is not working as expected. I have tried setting the ActionExecutingContext.Result to null and even have tried spooling up controllers via reflection and invoking their action methods. No dice. I was able to achieve it this way... protected override void OnActionExecuting(ActionExecutingContext filterContext) { filterContext.HttpContext.Response.Redirect("/MyView", false); base.OnActionExecuting(filterContext); } This seems like a hack, and there has to be a better way...

• Rename parameter in a WCF client interface

  - by user295479

  Hello everyone, I was wondering if there is a way to rename a parameter in a WCF client interface method ,just the same way I can rename methods or enumerations: Renaming methods: [System.Runtime.Serialization.DataMemberAttribute(Name = "intError")] public int ErrorCode {...} Renaming enumerations: public enum MyEnumeration: int { [System.Runtime.Serialization.EnumMemberAttribute()] None = 0, [System.Runtime.Serialization.EnumMemberAttribute(Value = "FirstOption")] First= 1, [System.Runtime.Serialization.EnumMemberAttribute()] SecondOption= 2, } Renaming parameters?? I want to rename an interface parameter named "error" which FxCop doesn't like. Any help will be appreciated. Thank you.

• How can a Delphi TForm / TPersistent object calculate its own deserialization time?

  - by mjustin

  For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

• Parameter passing become pointer for integer

  - by Kangkan

  I am working on a c/Linux app for a device. I consume a web service (in WCF/c#) and use gSOAP for the same. The issue is that the parameters in the service methods become pointers for simple data types like int, short etc also. I initially used the same service exposed as ASMX web service and the client proxy generated using gSOAP created methods with parameters passed as values. But once the service has been upgraded to WCF, all the parameters became pointers. Can somebody help?

• How Moles Isolation framework is implemented?

  - by Buu Nguyen

  Moles is an isolation framework created by Microsoft. A cool feature of Moles is that it can "mock" static/non-virtual methods and sealed classes (which is not possible with frameworks like Moq). Below is the quick demonstration of what Moles can do: Assert.AreNotEqual(new DateTime(2012, 1, 1), DateTime.Now); // MDateTime is part of Moles; the below will "override" DateTime.Now's behavior MDateTime.NowGet = () => new DateTime(2012, 1, 1); Assert.AreEqual(new DateTime(2012, 1, 1), DateTime.Now); Seems like Moles is able to modify the CIL body of things like DateTime.Now at runtime. Since Moles isn't open-source, I'm curious to know which mechanism Moles uses in order to modify methods' CIL at runtime. Can anyone shed any light?

• WCF - Compact Framework - Pull data from mobile client

  - by jagse

  Hello guys, I want to communicate xml serialized objects from the server to the client and the other way arround. Now it is (probably) easy to invoke methods from a mobile client (compact framework) using WCF, but is there a way so that the server can invoke methods on the client side or some other way to pull data from the client? I know that callback contracts are not available in the compact framework as you can see here: http://blogs.msdn.com/andrewarnottms/archive/2007/09/13/calling-wcf-services-from-netcf-3-5-using-compact-wcf-and-netcfsvcutil-exe.aspx Originally I thought of socket programming and of developing this by myself, then someone here mentioned WCF. But it seems like WCF only would work in a non mobile environment as I need callbacks. Anyone can help me with this? Is it possible to develop a two way communication with a desktop server and multiple mobile clients using WCF, or will I have to do socket programming? Thanks for any advice or any kind of help!

• Objective-C partial implementation of classes in separate files

  - by Aran Mulholland

  I am using core data and am generating classes from my data model. I implement custom methods in these classes, however when i regenerate i generate over the top so i end up copying and pasting a bit. What i would like to do is split my implementation files ('.m') so i can have one header file with multiple '.m' files. then i can keep my custom methods in one and not have to worry about erasing them when i regenerate. I use this technique in .NET a lot with its partial keyword. Is there anything similar in objective-C

• How to make and use first object in Objective C to store sender tag

  - by dbonneville

  I started with a sample program that simply sets up a UIView with some buttons on it. Works great. I want to access the sender tag from each button and save it. My first thought was to save it to a global variable but I couldn't get it to work right. I thought the best way would be to create an object with one property and synthesize it so I can get or set it as needed. First, I created GlobalGem.h: #import <Foundation/Foundation.h> @interface GlobalGem : NSObject { int gemTag; } @property int gemTag; -(void) print; @end Then I created GlobalGem.m: #import "GlobalGem.h" @implementation GlobalGem @synthesize gemTag; -(void) print { NSLog(@"gemTag value is %i", gemTag); } @end The sample code I worked from doesn't do anything I can see in "main" where the program initializes. They just have their methods and are set up to handle IBOutlet actions. I want to use this object in the IBOutlet methods. But I don't know where to create the object. In the viewDidLoad, I tried this: GlobalGem *aGem = [[GlobalGem alloc]init]; [aGem print]; I added reference to the .h file of course. The print method works. In the nslog I get "gemTag value is 0". But now I want to use the instance aGem in some of the IBOutlet actions. For instance, if I put this same method in one of the outlet actions like this: - (IBAction)touchButton:(id)sender { [aGem print]; } ...I get a build error saying that "aGem is undeclared". Yes, I'm new to objective c and am very confused. Is the instance I created, aGem, in the viewDidLoad not accessible outside of that method? How would I create an instance of a Class that I can store a variable value that any of the IBOutlet methods can access? All the buttons need to be able to store their sender tag in the instance aGem and I'm stuck. As I mentioned earlier, I was able to write the sender tag to a global variable I declared in the UIView .h file that came with the program, but I ran into issues using it. Where am I off?

• [C#] Namespace Orginization and Conventions

  - by Bob Dylan

  So I have a little bit of a problem. I working on a project in C# using The StackOveflow API. You can send it a request like so: http://stackoverflow.com/users/rep/126196/2010-01-01/2010-03-13 And get back something like this JSON response: [{"PostUrl":"1167342", "PostTitle":"Are ref and out in C# the same a pointers in C++?", "Rep":10}, {"PostUrl":"1290595", "PostTitle":"Where can I find a good tutorial on bubbling?", "Rep":10} ... So my problem is that I have some methods like GetJsonResponse() which return the above JSON and SaveTempFile() which saves that JSON response to a temporary file for later use. I not sure if I should create a class for them, or what namespace to put them under. Right now my current namespace hierarchy is like so: StackOverflow.Api.Json. So how should I organize these methods/classes/namespaces?

• Marshal struct to unmanaged array

  - by Pedro

  Hi guys, I have a C# struct to represent a cartesian vector, something like this: public struct Vector { private double x; private double y; private double z; //Some properties/methods } Now I have an unmanaged C dll that I need to call with P/Invoke. Some methods expect a double[3] parameter. The unmanaged C signature is something like void Cross(double a[3], double b[3], double c[3]); Is there any way to set up a P/Invoke signature so I can pass instances of my Vector struct and marshal them transparently to unmanaged double[3]? I would also need bidirectional marshaling as the unmanaged function needs to write the output to the argument array, so I guess I would need to marshal as LpArray. Any ideas? Thanks Pedro

• Handling button click in ASP.NET MVC 2 RTM

  - by Leniel Macaferi

  I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request.

• JAVA Classes in Game programming.

  - by Gabriel A. Zorrilla

  I'm doing a little strategy game to help me learn Java in a fun way. The thing is I visioned the units as objects that would self draw on the game map (using images and buffering) and would react to the mouse actions with listeners attached to them. Now, based on some tutorials I've been reading regarding basic game programming, all seems to be drawn in the Graphics method of my Map class. If a new unit emerges, i just update the Map.Graphics method, it's not as easy as making a new Unit object which would self draw... In this case, I'd be stuck with a whole bunch of Map methods instead of using classes for rendering new things. So my question is, is it possible to use classes for rendering units, interface objects, etc, or i'll have to create methods and just do some kind of structural programming instead of object oriented? I'm a little bit confused and I'd like to have a mental blueprint of how things would be organized. Thanks!

• Need to call COM component using reflection in .NET

  - by Usman

  I need to determine the COM component(unmanaged code) type and invoke the exposed interface's methods using reflection in C# at runtime. First What member of "Type" tells that type is COM component and we can take CLSID at runtime? Is Type.COMObject? I need to call methods of exposed interfaces as they called in unmanaged code using CoCreateInstance by passing CLSID and REFID ... I am using InvokeMember but it returns null or 0 as out parameter. How to pass out parameter in this case.? Is there any need to pass out parameter? As all my COM unmanaged code suppose to take last parameter as an OUT parameter and after executing it puts the result into that out param. But I've converted all my unmanaged COM code to .NET managed assemblies using tlbimp.exe.
