  • Can the get of a property be abstract and the set be virtual?

    - by K. Georgiev
    I have a base class like this: public class Trajectory{ public int Count { get; set; } public double Initial { get; set { Count = 1; } } public double Current { get; set { Count ++ ; } } } So, I have code in the base class, which makes the set-s virtual, but the get-s must stay abstract. So I need something like this: ... public double Initial { abstract get; virtual set { Count = 1; } } ... But this code gives an error. The whole point is to implement the counter functionality in the base class instead in all the derived classes. So, how can I make the get and set of a property with different modifiers?

  • Howto write a class where a property can be accessed without naming it.

    - by SchlaWiener
    I have a (dump) question regarding VB/C# I often use third party classes where I can access a child object with only specifying the id or key. Example: Instead of writing: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row.Items[1]; // DataRow has no Items property Object result = row.Items["colName"]; // Also not possible I use this code to access the members: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row[1]; Object result = row["colName"]; Can someone tell me how a class has to look like to support this syntax? My own class has a Dictionary that I want to access this way. MyClass["key"]; // <- that's what I want MyClass.SubItems["key"]; // <- that's how I use it now

  • How to make some functions of a class as private for third level of inheritance.

    - by Shantanu Gupta
    I have created a class say A which has some functions defined as protected. Now Class B inherits A and class C inherits B. Class A has private default constructor and protected parameterized constructor. I want Class B to be able to access all the protected functions defined in Class A but class C can have access on some of the functions only not all the functions and class C is inheriting class B. How can I restrict access to some of the functions of Class A from Class C ? Class A { private A(){} protected A(int ){} protected calc(){} protected allow(){} } Class B : A {} // calc() and allow() should be accessible here CLass C:B { // calc() should not be accessible here but allow() should be accessible here. }

  • Can you create ACLs with open vSwitch on XenServer 5.6FP1 without using the DVS appliance?

    - by bwizzy
    I have a pool of XenServer hosts running the Free version of XenServer 5.6 FP1. I was wondering if I change the network backend to use Open vSwitch if I can specify ACLs on individual network VIFs without needing to use the DVS appliance (distributed virtual switch) which requires an Advanced License or higher. Basically I'm looking for a way to isolate VMs on my network so that if a user had root access on the command line they couldn't access other servers they should not be able to (without using a VLAN).

  • Relevance of 'public' constructor in abstract class.

    - by Amby
    Is there any relevance of a 'public' constructor in an abstract class? I can not think of any possible way to use it, in that case shouldn't it be treated as error by compiler (C#, not sure if other languages allow that). Sample Code: internal abstract class Vehicle { public Vehicle() { } } The C# compiler allows this code to compile, while there is no way i can call this contructor from the outside world. It can be called from derived classes only. So shouldn't it allow 'protected' and 'private' modifiers only. Please comment.

  • Use Google Tasks in Thunderbird?

    - by BenA
    I'm using the GDataProvider along with Lightning to access my Google Calendar from Thunderbird. However I'd also like to have access to my Google Tasks as well. Does anybody know if this is possible at present? The GDataProvider wiki suggests that they will support this eventually (they've been stuck waiting for a Tasks API), but I'm wondering if anybody has managed to get this working any other way?

  • R: How can I use apply on rows of a data.frame and get out $column_name?

    - by John
    I'm trying to access $a using the following example: df<-data.frame(a=c("x","x","y","y"),b=c(1,2,3,4)) > df a b 1 x 1 2 x 2 3 y 3 4 y 4 test_fun <- function (data.frame_in) { print (data.frame_in[1]) } I can now access $a if I use an index for the first column: apply(df, 1, test_fun) a "x" a "x" a "y" a "y" [1] "x" "x" "y" "y" But I cannot access column $a with the $ notation: error: "$ operator is invalid for atomic vectors" test_fun_2 <- function (data.frame_in) { print (data.frame_in$a) } >apply(df, 1, test_fun_2) Error in data.frame_in$a : $ operator is invalid for atomic vectors Is this not possible?

  • How do API Keys and Secret Keys work?

    - by viatropos
    I am just starting to think about how api keys and secret keys work. Just 2 days ago I signed up for Amazon S3 and installed the S3Fox Plugin. They asked me for both my Access Key and Secret Access Key, both of which require me to login to access. So I'm wondering, if they're asking me for my secret key, they must be storing it somewhere right? Isn't that basically the same thing as asking me for my credit card numbers or password and storing that in their own database? How are secret keys and api keys supposed to work? How secret do they need to be? Are these applications that use the secret keys storing it somehow? Thanks for the insight.

  • trouble accessing localhost from ie7 running on parallels (win xp) on mac os x

    - by Karl R
    I'm running the app engine devserver on localhost:8080, and want to access it from ie7 running on parallels. I've tried all of the tips here: http://stackoverflow.com/questions/61449/how-do-i-access-the-host-from-vmware-fusion And they seem like they should work, particularly accessing via the gateway ip address. I've also sudo ipfw add allow tcp from 8080 to 8089 for good measure. Still no dice. I can access the external internet from ie7. The connection settings on parallels are set to 'Shared networking'. I'm out of ideas.

  • Multithread Communication

    - by Robert
    I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the MainThread to have access to it. Any ideas on how to get around this?

  • Twitter API + OAuth - 401 error developing locally using reverse SSH tunnel

    - by oliland
    I'm developing a django application which lets users connect their Twitter account. As I'm developing locally, I have set up a reverse SSH tunnel so that the Twitter API has a valid callback url (myserver.net): ssh -nNTR :6969:localhost:8000 myserver.net On successful authentication, Twitter passes back its OAuth access tokens to myserver.net, which in turn attempts to access Twitter's API, which returns a 401 error. I assume that because the callback is different to the address which is accessing the API (myserver.net / localhost), Twitter denies me access. I have tried this: export http_proxy="http://myserver.net:3128" Where myserver.net:3128 is running a Squid Proxy server to tunnel Twitter's API requests from my development machine so they appear to be coming from myserver, but receive the same 401 error. When I deploy to a server with a proper hostname / static IP address it works fine. What else do I need to do?

  • Type problem when including tuple

    - by Person
    I'm using Visual Studio 2008 with Feature Pack 1. I have a typedef like this typedef std::tr1::tuple<std::string, std::string, int> tileInfo with a function like this const tileInfo& GetTile( int x, int y ) const. In the implementation file the function has the exact same signature (with the added class name qualifier) and I am getting a redefinition: different type modifiers error. It seems to be looking for an int& instead of a tileInfo& When I mouse over the type of the function in the header, i.e. tileInfo& it brings up a little bar saying static const int tileInfo. I think this may be the problem, but I'm not sure what to do. Any help is appreciated, thanks.

  • Can a browser maintain multiple sessions with one server?

    - by Blaine
    Is there a way to maintain multiple sessions with one server within the browser? Here is what I am trying to accomplish: User1 has exclusive access to ContentA and User2 has exclusive access to ContentB. I want to be able to allow User3 to login multiple times, to allow access to ContentA and ContentB. I admit that this scenario seems almost silly but it stems from the fact that I can't change the way the server handles content permissions. Any ideas on how I could accomplish this without touching the server? In say Safari on the iPhone?

  • Problem with Models on Master Page View.

    - by user342514
    Have a problem with master page views and models. In the first image, I have a simple view in which I am trying to access the Model properties. None of the model properties are available at this time (this is the problem). If I use a <%= Model.blah % then you can see that the model properties are available. Second photo. In the last photo you will now see that I can access the Model properties that I was trying to access in the first photo. An error will be thrown if viewing this page if you don't first do <%= with the model. CS1061: 'object' does not contain a definition for 'User' and no extension method 'User' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) http://yfrog.com/8b43656447p So why is this happening?

  • Get the tags of a document in Subversion

    - by Onno
    I was wondering if there is a way to easily see the tags of a specific file in Subversion using the command line and/or TortoiseSVN. Most version control system allow you to see easily access the tags/labels of a file. When using TortoiseSVN I can do this when I access the "Revision Graph". This however is a operation that takes around 44 minutes. I consider this very hard work just to know what tags have been created for the file. Is there another way to do it? Or is there no way to instantaneously access tag information. Thanks, Onno

  • Allow users to ssh to specific user through ldap and stored public keys

    - by iElectric
    I recently setup gitolite, where users access git repository with "gitolite" user through ssh. Now I would like to integrate that into LDAP. Each user has pubkey in LDAP and if he has "git" objectClass, he would be able to access "gitolite" user through ssh. I know it's possible to store public keys in LDAP, I'm not sure if it possible to allow authentication in "gitosis" account based on objectClass. EDIT: To clarify, with objectClass git, user "foobar" would be able to login as "gitolite" through ssh

  • Prevent Concurrent File Changes: Windows Server 2003

    - by ThinkBohemian
    I have a program installed that writes configurations to disk installed on Windows Server 2003. When two administrators log into the machine at the same time, the last admin to save will persist their configurations, while the first admin's saves will be lost. Is there any way I can restrict access to a only this program so that only one person can edit it at a time? If not, is it possible to restrict user access to only one program?

  • Host's sys admins - can they view files?

    - by FullTrust
    Hi, Just a quick question. When using shared hosting, can system admins (employed by the host) access your files and read your database connectionstring details? Can they also access your database, and view the files, without a connectionstring? I'm assuming there's a certain level of trust, but is this possible/common? Thanks
