• Adding Service Reference to a WCF Service in Silverlight project defaulting to XmlSerialization for

  - by Shravan

  Hi, I am adding a WCF Service Reference in a Silverlight project, it is generating code with XmlSerialization attributes for DataMembers than SOAP Serialization. But, if the same WCF service reference is added in an ASP.Net project, is generating code with SOAP Serialization attribtues. Can anybody let me know what could be the cause for it, and how can I force reference to generate SOAP Serialization? XmlSerialization - [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1")] SOAP Serialization - [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")] These are the attributes in the code generated for types, which I am looking into when saying it is using XmlSerialization/SOAP Serialization

• Returning references while using shared_ptrs

  - by Goose Bumper

  Suppose I have a rather large class Matrix, and I've overloaded operator== to check for equality like so: bool operator==(Matrix &a, Matrix &b); Of course I'm passing the Matrix objects by reference because they are so large. Now i have a method Matrix::inverse() that returns a new Matrix object. Now I want to use the inverse directly in a comparison, like so: if (a.inverse()==b) { ... }` The problem is, this means the inverse method needs to return a reference to a Matrix object. Two questions: Since I'm just using that reference in this once comparison, is this a memory leak? What happens if the object-to-be-returned in the inverse() method belongs to a boost::shared_ptr? As soon as the method exits, the shared_ptr is destroyed and the object is no longer valid. Is there a way to return a reference to an object that belongs to a shared_ptr?

• Reference to a pointer question

  - by Yogesh Arora

  Please refer to the code below. In this code i am storing the const char* returned by test.c_str() into a reference. My question is Will the data be correctly refering to the contents of test. I am thinking that ptr returned by test.c_str() will be a temporary and if i bound it to a reference that reference will not be valid. Is my thinking correct class RefPtrTest { std::string test; StoringClass storingClass; public: RefPtrTest(): test("hello"), storingClass(test.c_str()) { } } where StoringClass is class StoringClass { const char*& data; public: StoringClass (const char*& input): data(input) { } }

• C++0x rvalue references and temporaries

  - by Doug

  (I asked a variation of this question on comp.std.c++ but didn't get an answer.) Why does the call to f(arg) in this code call the const ref overload of f? void f(const std::string &); //less efficient void f(std::string &&); //more efficient void g(const char * arg) { f(arg); } My intuition says that the f(string &&) overload should be chosen, because arg needs to be converted to a temporary no matter what, and the temporary matches the rvalue reference better than the lvalue reference. This is not what happens in GCC and MSVC. In at least G++ and MSVC, any lvalue does not bind to an rvalue reference argument, even if there is an intermediate temporary created. Indeed, if the const ref overload isn't present, the compilers diagnose an error. However, writing f(arg + 0) or f(std::string(arg)) does choose the rvalue reference overload as you would expect. From my reading of the C++0x standard, it seems like the implicit conversion of a const char * to a string should be considered when considering if f(string &&) is viable, just as when passing a const lvalue ref arguments. Section 13.3 (overload resolution) doesn't differentiate between rvalue refs and const references in too many places. Also, it seems that the rule that prevents lvalues from binding to rvalue references (13.3.3.1.4/3) shouldn't apply if there's an intermediate temporary - after all, it's perfectly safe to move from the temporary. Is this: Me misreading/misunderstand the standard, where the implemented behavior is the intended behavior, and there's some good reason why my example should behave the way it does? A mistake that the compiler vendors have somehow all made? Or a mistake based on common implementation strategies? Or a mistake in e.g. GCC (where this lvalue/rvalue reference binding rule was first implemented), that was copied by other vendors? A defect in the standard, or an unintended consequence, or something that should be clarified?

• Pass a captured named regular expression to URL dictionary in generic view

  - by Trent Jurewicz

  I am working with a generic view in Django. I want to capture a named group parameter in the URL and pass the value to the URL pattern dictionary. For example, in the URLConf below, I want to capture the parent_slug value in the URL and pass it to the queryset dictionary value like so: urlpatterns = patterns('django.views.generic.list_detail', (r'^(?P<parent_slugs>[-\w])$', 'object_list', {'queryset':Promotion.objects.filter(category=parent_slug)}, 'promo_promotion_list'), ) Is this possible to do in one URLConf entry, or would it be wiser if I create a custom view to capture the value and pass the queryset directly to the generic view from my overridden view?

• How to pass event to method?

  - by tomaszs

  I would like to create a method that takes as a argument an event an adds eventHandler to it to handle it properly. Like this: I have 2 events: public event EventHandler Click; public event EventHandler Click2; Now i would like to pass particular event to my method like this (pseudocode): public AttachToHandleEvent(EventHandler MyEvent) { MyEvent += Item_Click; } private void Item_Click(object sender, EventArgs e) { MessageBox.Show("lalala"); } ToolStripMenuItem tool = new ToolStripMenuItem(); AttachToHandleEvent(tool.Click); Is it possible or do I not understand it good? Edit: I've noticed with help of you that this code worked fine, and returned to my project and noticed that when I pass event declared in my class it works, but when I pass event from other class id still does not work. Updated above example to reflect this issue. What I get is this error: The event 'System.Windows.Forms.ToolStripItem.Click' can only appear on the left hand side of += or -=

• Creating reference movies for iPhone on the fly

  - by Mad Oxyn

  We are working on an online mobile video app. The videos we want to play on mobile phones are being generated by a server, as there can be dynamic content in the server (based on user input). Now for iPhone we would like to play the video in the best possible resolution based on the connection speed at the time of downloading the movie. This can be done using reference movies. However, because our videos are being generated on the fly, we need to generate this reference movie on the fly as well. Is there a way to generate reference movies on the fly on a Linux server using some command line tool, PHP or Java? Or on a DOS server maybe? Any help will be much appreciated.

• How to pass Remote Interface (aidl) throughout Activities ?

  - by Spredzy

  Hi All, I am developing an application using services and Remote interface. I have a question about passing the reference of my Remote interface throughout Activities. In my first Activity, I bind my service with my activity, in order to get a reference to my interface I use private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName arg0, IBinder service) { x = X.Stub.asInterface(service); } @Override public void onServiceDisconnected(ComponentName arg0) { // TODO Auto-generated method stub } }; x being the reference to my interface. Now I would like to access this interface from another activity, I see two ways to do it but I don't know which one is the "proper" way to do it : passing x with my intent when I call the new Activity redo this.bindService(new Intent(y.this,z.class), mConnection, Context.BIND_AUTO_CREATE); in the onCreate() of my new Activity What would you advice me to do ?

• Alternates to C++ Reference/Pointer Syntax

  - by Jon Purdy

  What languages other than C and C++ have explicit reference and pointer type qualifiers? People seem to be easily confused by the right-to-left reading order of types, where char*& is "a reference to a pointer to a character", or a "character-pointer reference"; do any languages with explicit references make use of a left-to-right reading order, such as &*char/ref ptr char? I'm working on a little language project, and legibility is one of my key concerns. It seems to me that this is one of those questions to which it's easy for a person but hard for a search engine to provide an answer. Thanks in advance!

• Fast way to pass a simple java object from one thread to another

  - by Adal

  I have a callback which receives an object. I make a copy of this object, and I must pass it on to another thread for further processing. It's very important for the callback to return as fast as possible. Ideally, the callback will write the copy to some sort of lock-free container. I only have the callback called from a single thread and one processing thread. I only need to pass a bunch of doubles to the other thread, and I know the maximum number of doubles (around 40). Any ideas? I'm not very familiar with Java, so I don't know the usual ways to pass stuff between threads.

• When are referenced Assemblies loaded?

  - by Daniel

  I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

• MVC Pass textbox to controller if not in a form tag

  - by user1679820

  I am working on and Microsoft MVC3 project and cannot pass a parameter which has been edited to the controller. It will only pass back the original set parameter For example: @Ajax.ActionLink("share file", InviteController.Actions.Result, InviteController.Name, new { message = Model.Message }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "popup", OnSuccess = "$('#popup').dialog('open')" }, new { id = "popup-button" }) <label>Personal Message <span class="optional-message">(optional)</span></label> @Html.TextAreaFor(x => x.Message) </div> This will pass the to the following controller but the 'message' parameter has the original message and not the updated message: public ActionResult Result(FormCollection coll, string message) { I'd love if someone could give me some advice. Many Thanks

• Getting Reference to Calling Activity from AsyncTask (NOT as an inner class)

  - by stormin986

  Is it at all possible, from within an AsyncTask that is NOT an inner class of the calling Activity class, to get a reference to the instance of Activity that initiated execution of the AsyncTask? I am aware of this thread, however it doesn't exactly address how to reference the calling Activity. Some suggest passing a reference to the Activity as a parameter to the AsyncTask constructor, however, it's reported that doing so will always result in a NullPointerException. So, I'm at a loss. My AsyncTask provides robust functionality, and I don't want to have to duplicate it as an inner class in every Activity that wants to use it. There must be an elegant solution.

• How do you pass an enum by reference?

  - by Darkenor

  I have an enum with four keys I'm taking as input for an interface program and I'd like to pass the enum by value to the interface function, which has become quite long. The enum is like this: enum MYKEYS { W, S, O, L }; There's also a boolean array that I have to pass by reference, which is also a little tricky. bool key[4] = { false, false, false, false }; Does anyone know the proper syntax to pass both of these as reference in a function, similar to: function(int & anintreference);

• How to reference filtered ng-repeat items from a controller in AngularJS

  - by ParkerDigital

  I have some JSON data that is rendered out via the ng-repeat directive, and the results are then filtered via some checkboxes/drop-downs, and some custom filter functions in my controller. I now want to add a function to my controller that is triggered by an 'ng-change' on some of the checkboxes, that can reference the current list of items in my 'ng-repeat'. I realise I can reference these values from a custom filter, for example $scope.filterProvider = function(item), but this function is then called for each and every item in the ng-repeat, which isn't what I want - I want the function to just be called each time a checkbox is checked/unchecked, and I need that function to be able to reference the items in my ng-repeat...does that make sense to anyone?! And if so, does anyone know how I can do that? Thanks :-)

• How to pass bash script arguments to a subshell

  - by Ralf Holly

  I have a wrapper script that does some work and then passes the original parameters on to another tool: #!/bin/bash # ... other_tool -a -b "$@" This works fine, unless the "other tool" is run in a subshell: #!/bin/bash # ... bash -c "other_tool -a -b $@" If I call my wrapper script like this: wrapper.sh -x "blah blup" then, only the first orginal argument (-x) is handed to "other_tool". In reality, I do not create a subshell, but pass the original arguments to a shell on an Android phone, which shouldn't make any difference: #!/bin/bash # ... adb sh -c "other_tool -a -b $@"

• Digest authentication not working: endless cycles of asking for user/pass

  - by bcmcfc

  I'm trying to setup my SVN repository for access remotely. In doing so I have some settings under Apache's dav_svn.conf file. When navigating to hostname/svn, or using Tortoise to do the same it prompts for the user name and password as expected. However, when entering the correct user name and pass that were set in the password file linked to under AuthUserFile it just asks for the credentials again. I think I'm probably missing something simple? The server is running Ubuntu Server 9.10. Accessing SVN remotely does currently work if the authentication lines of dav_svn.conf are commented out. These are the contents of the dav_svn.conf file: <Location /svn> DAV svn SVNPath /home/svn/repo AuthType Digest AuthName "Subversion Repository" AuthDigestDomain /svn/ AuthUserFile /etc/svn_authfile Require valid-user </Location>

• How to reference other locations in making multi-boot live cd

  - by Nrew

  There is a tool in pen drive linux that allows you to boot directly with multiple iso files. And here is a sample in the menu.lst which allows you to choose which iso file you want to boot. title Fedora 13 find --set-root /Fedora-12-i686-L.iso map /ubuntu-10.04-desktop-i386.iso (0xff) map --hook root (0xff) kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent iso-scan/filename=/ubuntu-10.04-desktop-i386.iso splash initrd /casper/initrd.lz I'm just using it on my 8gb flash drive and the location of the iso file is in the flash drive itself. Is it possible to reference other locations. So that I could boot from it, without limitations. because the flash drive can only contain 8gb of data. Is it possible? Anyone here tried this before?

• Pass quoted argument string to Start-Process in PowerShell

  - by Luke Puplett

  Hello I'm trying to very simply run an executable and pass a file path in as the first argument. In DOS, this would be the command: import.exe "C:\Some Path\With\Spaces.txt" By placing the path in quotes, the path is correctly parsed as the first token into the executable. In PowerShell I'm using this: $feeds = dir 'T:\Documents\Company\Product Development\Data foreach ($feed in $feeds) { start -FilePath import.exe -ArgumentList $feed.FullName } The problem with the Start-Process cmdlet in PowerShell is that it uses a string array for arguments, so the path is broken up and sent to the executable as separate tokens. Quotes in PowerShell force $feed.FullName to be treated literally. Double quotes "" make PowerShell not see anything in the argument list. "The argument is null or empty." it tells me. I expect that this is a known headache and has had a known workaround from day one. Thanks Luke
