  • Visual Studio: How to override the default "Build Action" for certain extension types per project or solution?

    - by Lukasz Podolak
    I'm serving my asp.net mvc views from many assemblies and copying views to the main application on post-build event. This works, however, I realized, that when I change something in view and just hit F5, changes are not included. What I have to do to see changes is to: save, build<- explicitly clicking, and then hit F5. However, it's pretty annoying solution. I discovered that setting Build action to "Embedded Resource" on view solves the problem as well, however other devs may not remember that they have to do this after adding every view to the solution. Is there a way to override the default build action for certain file extensions, such as: *.aspx, *.ascx in project or (better) in solution ? What I've found is an ability to add this setting globally, per machine, but I do not want to do that (link: http://blog.andreloker.de/post/2010/07/02/Visual-Studio-default-build-action-for-non-default-file-types.aspx) Any ideas ?

  • How to accomplish covariant return types when returning a shared_ptr?

    - by Kyle
    using namespace boost; class A {}; class B : public A {}; class X { virtual shared_ptr<A> foo(); }; class Y : public X { virtual shared_ptr<B> foo(); }; The return types aren't covariant (nor are they, therefore, legal), but they would be if I was using raw pointers instead. What's the commonly accepted idiom to work around this, if there is one?

  • Why bother to limit the types imported from a python package?

    - by Fast Fish
    When using many IDEs that support autocompletion with Python, things like this will show warnings, which I find annoying: from eventlet.green.httplib import BadStatusLine When switching to: rom eventlet.green.httplib * The warnings go away. What's the benefit to limiting imports to a specific set of types you'll use? Is the parsing faster? Reduces collisions? What other point is there? It seems the state of python IDEs and the nature of the typing system makes it hard for many IDEs to fully get right when a type import works and when it doesn't.

  • why do we have to send the const " type " reference instead of just the types name to the constructo

    - by hamza
    i m trying to make a simple program ( & yes , it is a homework ) that can generate Dates , & like most of normal people : i made my Class attributes private , i tried to send the same type that i m working on to the constructor but the complier have not accept it , i did some research & i found out that in cases like that people generously send a const "type" reference to the constructor witch meant to me that have not understand OOP well so why do we have to send the const " type " reference instead of just the types name to the constructor ? & please give me some links or websites for beginners PS : sorry for my English

  • How to maintain fixed size of C variable types over different machines?

    - by Alex
    I've all this kind of functions. ssize_t fuc1(int var1, void *buf, size_t count); int func2(char *charPtr, int mode, int dev); short func3( long var2); problem is that data types in C has different sizes when compiled on different machines(64bit & 32bit). This is true for even void*. For some reasons. I need to ensure that these sizes all are same on every machine(64bit & 32bit). So, how should I modify these ?

  • Ruby on Rails: How can I authenticate different user types from one place?

    - by sscirrus
    Hi everyone! This is my first post on Stack Overflow. I am trying to build a system that authenticates three types of user with completely different site experiences: Customers, Employers, and Vendors. I'm thinking of using a polymorphic 'User' table (using AuthLogic) with username, password, and user_type (+ AuthLogic's other required fields). If this is a good way to go, how do I set this up so after authenticating an user_id with a user_type the standard way, I can direct the user to the page that's right for them? Thanks.

  • Should GSON ignore varying types if they're not used in a class?

    - by loeschg
    I'm making an API call that returns JSON which has a particular field which either returns false or a map depending on content. It's a field that I don't care about. I expected GSON to ignore this particular field, though it doesn't seem to be. The object generation fails with the following message: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 403560 I've seen this particular question (Gson deserialize json with varying value types). I want to make sure I need to make a custom deserializer before doing so. I'm wondering if I may have another issue. edit: Example: "anonymous_flag": { } vs "anonymous_flag": "yes" Another Edit: I actually had the field in my model object... I was referencing the wrong class. Judge away :)

  • SvcUtil and /dconly generates XSD's for data types NOT marked with the DataContract attribute.

    - by Bellerephon
    Has anyone ever encountered a problem with Svcutil and the /dconly option where it generates metadata for EVERY data type in an Assembly, even if it is NOT marked with with the [DataContract()] attribute? It also appears to be generating metadata for types only referenced in the code, such as XmlDictionaryReaderQuotas even though these are not a part of the physical assembly that I generated metadata on. Some info: Using the .NET 4.0 version of SvcUtil. Does not matter if class is empty or not. No references are specified in the command line for SvcUtil. Command line: "C:\In Progress Work (Prospective)\Prospective Server\Prospective Server\Management\Prospective.Server.Server.NET40.Debug.AnyCPU.dll" /nologo /t:metadata /d:"C:\In Progress Work (Prospective)\Prospective Server\Prospective Server\Management" /dconly

  • C++: How to use types that have not been defined?

    - by Jen
    C++ requires all types to be defined before they can be used, which makes it important to include header files in the right order. Fine. But what about my situation: Bunny.h: class Bunny { ... private: Reference<Bunny> parent; } The compiler complains, because technically Bunny has not been completely defined at the point where I use it in its own class definition. This is not sufficient: class Bunny; class Bunny { ... private: Reference<Bunny> parent; } Apart from re-writing my template class Reference so it takes a pointer type (in which case I can use the forward declaration of Bunny), I don't know how to solve this. Any suggestions?

  • How can I check the type of an object against a list of types?

    - by RookieRick
    Given a collection IEnumerable<Type> supportedTypes What's the best way to check whether a given object is one of those types (or a derived type)? My first instinct was to do something like: // object target is a parameter passed to the method in which I'm doing this. if (supportedTypes.Count( supportedType => target is supportedType ) > 0) { // Yay my object is of a supported type!!! } ..but that doesn't seem to be working. Can I not use the "is" keyword in a lambda expression like this?

  • Why are Java primitive types' modifiers `public`, `abstract`, & `final`?

    - by oconnor0
    In the process of doing some reflection on Java types, I came across an oddity that I do not understand. Inspecting int for its modifiers returns public, abstract, and final. I understand public and final, but the presence of abstract on a primitive type is non-obvious to me. Why is this the case? Edit: I am not reflecting on Integer but on int: import java.lang.reflect.Modifier; public class IntegerReflection { public static void main(final String[] args) { System.out.println(String.format("int.class == Integer.class -> %b", int.class == Integer.class)); System.out.println(String.format("int.class modifiers: %s", Modifier.toString(int.class.getModifiers()))); System.out.println(String.format("Integer.class modifiers: %s", Modifier.toString(Integer.class.getModifiers()))); } } The output when run: int.class == Integer.class -> false int.class modifiers: public abstract final Integer.class modifiers: public final

  • Which file types are worth compressing (zipping) for remote storage? For which of them the compresse

    - by user193655
    I am storing documents in sql server in varbinary(max) fileds, I use filestream optionally when a user has: (DB_Size + Docs_Size) ~> 0.8 * ExpressEdition_Max_DB_Size I am currently zipping all the files, anyway this is done because the Document Read/Write work was developed 10 years ago where Storage was more expensive than now. Many files when zipped are almost as big as the original (a zipped pdf is about 95% of original size). And anyway unzipping has some overhead, that becomes twice when I need also to "Check-in"/Update the file because I need to zip it. So I was thinking of giving to the users the option to choose whether the file type will be zipped or not by providing some meaningful default values. For my experience I would impose the following rules: 1) zip by default: txt, bmp, rtf 2) do not zip by default: jpg, jpeg, Microsoft Office files, Open Office files, png, tif, tiff Could you suggest other file types chosen among the most common or comment on the ones I listed here?

  • Would it be useful to change java to support both static and dynamic types?

    - by James A. N. Stauffer
    What if a Java allow both static and dynamic types. That might allow the best of both worlds. i.e.: String str = "Hello"; var temp = str; temp = 10; temp = temp * 5; Would that be possible? Would that be beneficial? Do any languages currently support both and how well does it work out? Here is a better example (generics can't be used but the program does know the type): var username = HttpServletRequest.getSession().getAttribute("username");//Returns a String if(username.length() == 0) { //Error }

  • Why are types found on an imported namepace but not on a fully qualified namespace after retargeting the framework?

    - by Paul Ferguson
    We've just re-targeted a VB.NET project from .Net 2.0 to 3.5. Various framework types are now missing from our project. Wherever the type is referenced using a fully qualified namespace it's missing. If the relevant namespace is imported for the type; it's found. For example, this doesn't find the type Object, with compiler error "System.Object is not defined.": Public Class Foo Inherits System.Object End Class However, this works ok: Imports System Public Class Foo Inherits [Object] End Class I've already tried re-opening the solution with no success.

  • Java: Is it possible to have a generic class that only takes types that can be compared?

    - by mr popo
    I wanted to do something along the lines of: public class MyClass<T implements Comparable> { .... } But I can't, since, apparently, generics only accept restrictions with subclasses, and not interfaces. It's important that I'm able to compare the types inside the class, so how should I go about doing this? Ideally I'd be able to keep the type safety of Generics and not have to convert the T's to Object as well, or just not write a lot of code overall. In other words, the simplest the better.

  • EntityFramework 4.0: can you return different types depending on data in the database?

    - by user200341
    I have a Media table in the database. I also have an IMedia interface. I have two different media types that implements the same interface: 1) AudioMedia 2) PictureMedia What I wonder here, is if I can use EntityFramework (I'm using an EDMX file but I have my models in a separate library, with automatic code generation turned off), and depending on the data in the database, select what type to get (AutioMedia or PictureMedia). Since they are both implementing the same interface (could be changed to an abstract class if needed I suppose), I'm thinking that somewhere along the way you could specify what class it should be. I should perhaps point out that I have a class that inherits from ObjectContext to access the objects. Perhaps there is something that that can be done?

  • How does make_pair know the types of its args?

    - by bobobobo
    The definition for make_pair in the MSVC++ "utility" header is: template<class _Ty1, class _Ty2> inline pair<_Ty1, _Ty2> make_pair(_Ty1 _Val1, _Ty2 _Val2) { // return pair composed from arguments return (pair<_Ty1, _Ty2>(_Val1, _Val2)); } I use make_pair all the time though without putting the argument types in angle brackets: map<string,int> theMap ; theMap.insert( make_pair( "string", 5 ) ) ; Shouldn't I have to tell make_pair that the first argument is std::string and not char* ? How does it know?

  • Is it possible to have file filters for multiple extension types?

    - by Jon Cage
    I'm using a standard Windows FileDialog to allow the user to select some files. I'd like to filter out only the file types I'm interested in though (lets call them *.a and *.b). Is there any way to do this without using *.*? I've tried the following but it fails to match any files at all: this->openFileDialog1->DefaultExt = L"*.a,*.b"; this->openFileDialog1->FileName = L"openFileDialog1"; this->openFileDialog1->Filter = L"My Data Files (*.a,*.b)|*.a,*.b";

  • Will having 2 MX records pointing to different mail server types cause delivery issues?

    - by Lyken
    I've inherited a setup where the mail server is exchange 2010. For some reason, I'm not sure why there is 2 MX records setup. One being the exchange server which is the higher priority while the external (non-exchange) server is the secondary mx record. I don't believe this was done for redundancy reasons as the other mail server is not set to route mail back to the exchange server (it's just the webhosts email for their hosting) The client has been experiencing disappearing email, however after my investigations its not actually disappearing, but exchange is successfully receiving the mail and then passing it on to the external server. It isn't happening all the time, just with some email messages from some domains. My question: Is exchange passing the mail on because it can see the secondary MX record and is configured (somewhere) to send mail out? If so, how do I stop it? Is it as easy as just removing the second MX record pointing to the external mail server and exchange will stop passing mail on? I'm not exchange expert so I'm kinda stumped. Exchange MX tools are saying everything is setup and configured correctly from an external point of view.

  • Is it generally a bad idea to have other types of virtual appliances installed along side a firewall

    - by MGSoto
    I want to run my Firewall/NAT software (pfsense) and an internal NAS (looking at freenas right now) for my SOHO on one machine. Right now I have them separated on two different machines, but I'd like to consolidate them. Is this generally a bad idea? I see the security concern where if the firewall or host OS is compromised, then your data is essentially screwed. But is it really a concern for me?

  • Why are there two types of Adobe Flash Player download / update?

    - by w3d
    Adobe Flash Player checks for updates at startup. If updates are required the Adobe dialog pops up with a [Download] button. Usually when I hit the [Download] button it downloads it straight away with a progress bar that zips across the dialog. I then get the option to install it. All good. However, sometimes when I hit the [Download] button it takes me to the website: https://get3.adobe.com/flashplayer/update/plugin/ Which presents me with an [Update now] button (and to install McAfee!). What is this for? Why didn't it download and install in the "usual" way? So, why are there apparently two different update methods for what appears to be the same thing? One is nice and swish and integrated into the updater, the other more long winded. In fact, I don't [Update now] when it takes me to the website, because I'm like "Hey, what's this?!"

  • Is there a faster way to change default apps associated with file types on OS X?

    - by Lri
    Is there anything more convenient than using RCDefaultApp or Magic Launch, or just repeatedly pressing the Change All buttons in Finder's information panels? I thought about writing a shell script that would modify the CFBundleDocumentTypes arrays in Info.plist files. But each app has multiple keys (sometimes an icon) that would need to be changed. lsregister can't be used to make specific modifications to the Launch Services database. $ `locate lsregister` -h lsregister: [OPTIONS] [ <path>... ] [ -apps <domain>[,domain]... ] [ -libs <domain>[,domain]... ] [ -all <domain>[,domain]... ] Paths are searched for applications to register with the Launch Service database. Valid domains are "system", "local", "network" and "user". Domains can also be specified using only the first letter. -kill Reset the Launch Services database before doing anything else -seed If database isn't seeded, scan default locations for applications and libraries to register -lint Print information about plist errors while registering bundles -convert Register apps found in older LS database files -lazy n Sleep for n seconds before registering/scanning -r Recursive directory scan, do not recurse into packages or invisible directories -R Recursive directory scan, descending into packages and invisible directories -f force-update registration even if mod date is unchanged -u unregister instead of register -v Display progress information -dump Display full database contents after registration -h Display this help
