  • How to create a template to display data from a class in WPF

    - by Dave Colwell
    Hey I have a data layer which is returning lists of classes containing data. I want to display this data in my form in WPF. The data is just properties on the class such as Class.ID, Class.Name, Class.Description (for the sake of example) How can i create a custom control or template an existing control so that it can be given one of these classes and display its data in a data-bound fashion. Thanks :)

  • Use the keyword class as a variable name in C++

    - by Leif Andersen
    I am having trouble writing C++ code that uses a header file designed for a C file. In particular, the header file used a variable name called class: int BPY_class_validate(const char *class_type, PyObject *class, PyObject *base_class, BPY_class_attr_check* class_attrs, PyObject **py_class_attrs); This works in C as class isn't taken as a keyword, but in C++, class is. So is there anyway I can #include this header file into a c++ file, or am I out of luck? Thank you.

  • How much to put in a Repository class?

    - by chobo
    When using the repository pattern is it recommended to have one Repository class for each database table? Would I also map one service layer class to one repository class. I'm having a hard time trying to understand how much stuff one repository or service layer class should have. Thanks!

  • Point one style class to another?

    - by user246114
    Hi, I have a css class like: .foo { background-color: red; } then I have a class specified for a list: .list1 li { background-color: tan; } is it possible to set one style class to just point to another? Something like: .list1 li { .foo; } not sure how to articulate that - I just want the .list li style to be whatever I define for the .foo class. Thanks

  • RSpec - mocking a class method

    - by Chris Kilmer
    I'm trying to mock a class method with rspec: lib/db.rb class Db def self.list(options) Db::Payload.list(options) end end lib/db/payload.rb class Db::Payload def self.list(options={}) end end In my spec, I'm trying to setup the expectation Db::Payload.list will be called when I call Db.list: describe Db do before(:each) do @options = {} Db::Payload.should_receive(:list).with(@options) end it 'should build the LIST payload' do Db.list(@options) end end The problem is that I am always receiving the following error: undefined method `should_receive' for Db::Payload:Class Any help understanding this error would be most appreciated :-)

  • Struct inside a class

    - by Balakrishnan
    I have a class definition of the form class X { public: //class functions private: A_type *A; //other class variables }; and struct A_type is defined as struct A_type { string s1,s2,s3; }; Inside the constructor, I allocate appropriate memory for A and try A[0].s1="somestring"; It shows segmentation fault. Is this kind of declaration invalid, or am I missing something

  • C++ class is not recognizing string data type

    - by reallythecrash
    I'm working on a program from my C++ textbook, and this this the first time I've really run into trouble. I just can't seem to see what is wrong here. Visual Studio is telling me Error: identifier "string" is undefined. I separated the program into three files. A header file for the class specification, a .cpp file for the class implementation and the main program file. These are the instructions from my book: Write a class named Car that has the following member variables: year. An int that holds the car's model year. make. A string that holds the make of the car. speed. An int that holds the car's current speed. In addition, the class should have the following member functions. Constructor. The constructor should accept the car's year and make as arguments and assign these values to the object's year and make member variables. The constructor should initialize the speed member variable to 0. Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make and speed member variables. There are more instructions, but they are not necessary to get this part to work. Here is my source code: // File Car.h -- Car class specification file #ifndef CAR_H #define CAR_H class Car { private: int year; string make; int speed; public: Car(int, string); int getYear(); string getMake(); int getSpeed(); }; #endif // File Car.cpp -- Car class function implementation file #include "Car.h" // Default Constructor Car::Car(int inputYear, string inputMake) { year = inputYear; make = inputMake; speed = 0; } // Accessors int Car::getYear() { return year; } string Car::getMake() { return make; } int Car::getSpeed() { return speed; } // Main program #include <iostream> #include <string> #include "Car.h" using namespace std; int main() { } I haven't written anything in the main program yet, because I can't get the class to compile. I've only linked the header file to the main program. Thanks in advance to all who take the time to investigate this problem for me.

  • CQRS - Benefits

    - by Dylan Smith
    Thanks to all the comments and feedback from the last post I think I have a better understanding now of the benefits of CQRS (separate from the benefits of Event Sourcing). I’m going to try and sum it up here, and point out some areas where I could still use some advice: CQRS Benefits Sounds like the primary benefit of CQRS as an architecture is it allows you to create a simpler domain model by sucking out everything related to queries. I can definitely see the benefit to this, in general the domain logic related to commands is the high-value behavior in the software, but the logic required to service the queries would add a lot of low-value “noise” to the domain model that would dilute the high-value (command) behavior – sorting, paging, filtering, pre-fetch paths, etc. Also the most appropriate domain structure for implementing commands might not be the most optimal for implementing queries. To paraphrase Greg, this usually results in a domain model that is mediocre at both, piss-poor at one, or more likely piss-poor at both commands and queries. Not only will you be able to simplify your domain model by pulling out all the query logic, but at least a handful of commands in most systems will probably be “pass-though” type commands with little to no logic that just generate events. If these can be implemented directly in the command-handler and never touch the domain model, this allows you to slim down the domain model even more. Also, if you were to do event sourcing without CQRS, you no longer have a database containing the current state (only the domain model would) which makes it difficult (or impossible) to support ad-hoc querying and/or reporting that is common in most business software. Of course CQRS provides some great scalability benefits, not only scalability but I have to assume that it provides extremely low latency for most operations, especially if you have an asynchronous event bus. I know Greg says that you get a 3x scaling (Commands, Queries, Client) of your ability to perform parallel development, but IMHO, it seems like it only provides 1.5x scaling since even without CQRS you’re going to have your client loosely coupled to your domain - which is still a great benefit to be able to realize. Questions / Concerns If all the queries against an aggregate get pulled out to the Query layer, what if the only commands for that aggregate can be handled in a “pass-through” manner with the command handler directly generating events. Is it possible to have an aggregate that isn’t modeled in the domain model? Are there any issues or downsides to this? I know in the feedback from my previous posts it was suggested that having one domain model handling both commands and queries requires implementing a lot of traversals between objects that wouldn’t be necessary if it was only servicing commands. My question is, do you include traversals in your domain model based on the needs of the code, or based on the conceptual domain model? If none of my Commands require a Customer.Orders traversal, but the conceptual domain includes the concept of a set of orders belonging to a customer – should I model that in my domain model or not? I like the idea of using the Query side of the architecture as a place to put junior devs where the risk of them screwing something up has minimal impact. But I’m not sold on the idea that you can actually outsource it. Like I said in one of my comments on my previous post, the code to handle a query and generate DTO’s is going to be dead simple, but the code to process events and apply them to the tables on the query side is going to require a significant amount of domain knowledge to know which events to listen for to update each of the de-normalized tables (and what changes need to be made when each event is processed). I don’t know about everybody else, but having Indian/Russian/whatever outsourced developers have to do anything that requires significant domain knowledge has never been successful in my experience. And if you need to spec out for each new query which events to listen to and what to do with each one, well that’s probably going to be just as much work to document as it would be to just implement it. Greg made the point in a comment that doing an aggregate query like “Total Sales By Customer” is going to be inefficient if you use event sourcing but not CQRS. I don’t understand why that would be the case. I imagine in that case you’d simply have a method/property on the Customer object that calculated total sales for that customer by enumerating over the Orders collection. Then the application services layer would generate DTO’s off of the Customers collection that included say the CustomerID, CustomerName, TotalSales, or whatever the case may be. As long as you use a snapshotting implementation, I don’t see why that would be anymore inefficient in a DDD+Event Sourcing implementation than in a typical DDD implementation. Like I mentioned in my last post I still have some questions about query logic that haven’t been answered yet, but before I start asking those I want to make sure I have a strong grasp on what benefits CQRS provides.  My main concern with the query logic was that I know I could just toss it all into the query side, but I was concerned that I would be losing the benefits of using CQRS in the first place if I did that.  I want to elaborate more on this though with some example situations in an upcoming post.

  • DHCP and DNS services configuration for VOIP system, windows domain, etc

    - by Stemen
    My company has numerous physical offices (for purposes of this discussion, 15 buildings). Some of them are well-connected to our primary data center via fiber. Others will be connected to the data center by P2P T1. We are in the beginning stages of implementing an Avaya VOIP telephone system, and we will be replacing a significant portion of our network infrastructure in the process. In tandem with the phone system implementation, we are going to be re-addressing some of our networks, and consolidating most of our Windows domains into one (not all domains, just most). We currently have quite a few Windows domains, and they of course each have their own DNS zones. A few of those networks currently use DHCP, but the majority use static IP assignments for every device. I'm tired of managing static assignments -- I want to use DHCP configuration on everything except servers. Printers and etc will have DHCP reservations. The new IP phones will need to get IP addresses from DHCP, though they need to be in a separate VLAN from the computers/printers/etc. The computers and printers need to be registered in DNS. That's currently handled by the Windows DHCP servers on each of the respective domains. We need to place a priority on DHCP and DNS being available on a per-site basis (in case something were to interrupt the WAN connection) for computers and (primarily) phones. Smaller locations (which will have IP phones but not be a member of any Windows domain) will not have any Windows DNS/DHCP server(s) available. We also are looking for the easiest way to replace a part if it were to fail. That is to say, if a server/appliance/router hosting DHCP were to crash hard, and we couldn't extremely quickly recover the DHCP reservations and leases (and subsequently restore them onto a cold spare), we anticipate that bad things could happen. What is the best idea for how to re-implement DNS and DHCP keeping all of the above in mind? Some thoughts that have been raised (by myself or my coworkers): Use Windows DNS and DHCP servers, where they exist, and use IP helpers to route DHCP requests to some other Windows server if necessary. May not be acceptable if the WAN goes down and clients don't get a DHCP response. Use Windows DNS (everywhere, over WAN in some cases) and a mix of Windows DHCP and DHCP provided by Cisco routers. Every site would be covered for DHCP, but from what I've read, Cisco routers can't handle dynamic registration of DHCP clients to Windows DNS servers, which might create a problem where Cisco routers are used for DHCP. Use Windows DNS (everywhere, over WAN in some cases) and a mix of Windows DHCP and DHCP provided by some service running on an extremely low-price linux server. Is there any such software that would allow DHCP leases granted by these linux boxes to be dynamically registered on the Windows DNS servers? Come up with a Linux solution for both DNS and DHCP, and deploy low-price linux servers to every site. Requirements would be that the DNS zone be multi-master (like Windows DNS integrated with Active Directory), that DHCP be able to make dynamic DNS registrations in that zone, for every lease (where a hostname is provided and is thus possible), and that multiple servers be either authoritative for the same DHCP scope or at least receiving a real-time copy / replication / sync of the leases table so that if one server dies, we still know which MAC has what address. Purchase dedicated DNS/DHCP appliances, deploying to all sites. From what I read/see, this solves all of our technical problems. Then come the financial problems... I don't have a ton of money to spend on this. Or, some other solution that we've thus far overlooked and will consider upon recommendation. Can Cisco routers or Windows servers sync DHCP lease tables so that multiple servers can be authoritative (or active/passive for all I care) for the same scope, in case one of the partners were to fail? I've read online (repeatedly) that ISC's DHCP is able to maintain the same lease table across multiple servers, in order to solve this problem. Does anyone have any experience or advice to regarding that?

  • Email forwarding from my domain to gmail - FAIL

    - by pitosalas
    [There are numerous similar questions on ServerFault but I couldn't find one that was exactly on point] Background: I use Gmail for my email client. My email is [email protected]. However the email that people communicate to me with is [email protected]. I run the server that hosts www.example.com and other domains, at ServerBeach. Up to yesterday, I had SENDMAIL painlessly just forward emails to [email protected] to [email protected] and everything was fine, for several years in fact. Suddenly my email stopped working - that is, my gmail account stopped receiving emails via the forward from my server. Looking into it I found a bunch of emails sitting on my server with content like this: ... while talking to gmail-smtp-in.l.google.com.: RCPT To: <<< 450-4.2.1 The user you are trying to contact is receiving mail at a rate that <<< 450-4.2.1 prevents additional messages from being delivered.

But I don't know really what's going on nor do I see whatever emails might be involved. I've read stuff on zoneedit.com that sounds like they might have a solution in their service for what I am trying to do. I also read a lot about admining DNS and SENDMAIL and tried various things, but nothing works. Can you tell from my description what is going on that caused GMail's server to stop accepting email from my server and is there a way to stop it? What is the 'correct' way to configure things so that emails to [email protected] behave as if they were sent to [email protected]? Thanks so much!

  • Identifying the cause of my DNS failure (domain not propagating)

    - by thejartender
    I have set up a DNS server with the help of two helpful tutorials: http://linuxconfig.org/linux-dns-server-bind-configuration http://ulyssesonline.com/2007/11/07/how-to-setup-a-dns-server-in-ubuntu/ I am using: Ubuntu Bind9 and had issues I tried negating on my own thanks to a question I posted here earlier that pointed out my mistake of using rfc 1918 addresses in my previous SOA record: $TTL 3D @ IN SOA ns.thejarbar.org. email.

I read the ranges that are used under rfc 1918 and modified my routers resource pool to assign LAN devices IP(s) within the 30.0.0.0 range and now modified my SOA to: $TTL 600 @ IN SOA ns.thejarbar.org. email.

I can ping my nameserverver ns.thejarbar.organd it gives me the correct isp IP address, but my domain never seems to propagate to my nameserver. I have searched for a concise tutorial that covers setting up a DNS with a nameserver that hosts (my) or the site. I am fully aware that this is not recommended and am using this for my learning purposes. Getting to the question, due to the lack of information in tutorials I looked at (nothing about rfc 1918 and no example of swapping these with ISP IP) is my router modification going to help me as it does not seem to be. I have also tried as recommended using my ISP IP instead of the values I posted. My site never propagated to my nameserver. What could be causing this? I have run dig thejarbar.org @88.89.190.171 and get an authorative response. Can anyone assist me with the final steps I may be missing here?

  • Cascading persist and existing object

    - by user322061
    Hello, I am working with JPA and I would like to persist an object (Action) composed of an object (Domain). There is the Action class code: @Entity(name="action") @Table(name="action") public class Action { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) @Column(name="num") private int num; @OneToOne(cascade= { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @JoinColumn(name="domain_num") private Domain domain; @Column(name="name") private String name; @Column(name="description") private String description; public Action() { } public Action(Domain domain, String name, String description) { super(); this.domain=domain; this.name=name; this.description=description; } public int getNum() { return num; } public Domain getDomain() { return domain; } public String getName() { return name; } public String getDescription() { return description; } } When I persist an action with a new Domain, it works. Action and Domain are persisted. But if I try to persist an Action with an existing Domain, I get this error: javax.persistence.EntityExistsException: Exception Description: Cannot persist detached object [isd.pacepersistence.common.Domain@1716286].

  • java 6 web services share domain specific classes between server and client

    - by user173446
    Hi all, Context: Considering below defined Engine class being parameter of some webservice method. As we have both server and client in java we may have some benefits (???) in sharing Engine class between server and client ( i.e we may put in a common jar file to be added to both client and server classpath ) Some benefits would be : we keep specific operations like 'brushEngine' in same place build is faster as we do not need in our case to generate java code for client classes but to use them from the server build) if we later change server implementation for 'brushEngine' this is reflected automatically in client . Questions: How to share below detailed Engine class using java 6 tools ( i.e wsimport , wsgen etc )? Is there other tools for java that can achieve this sharing ? Is sharing a case that java 6 web services support is missing ? Can this case be reduced to other web service usage patterns? Thanks. Code: public class Engine { private String engineData; public String getData(){ return data; } public setData(String value){ this.data = value; } public void brushEngine(){ engineData = "BrushedEngine"+engineData; } }

  • HA for Resque & Redis

    - by Chris Go
    Trying to avoid SPOFs for Resque and Redis. Ultimately the client is going to be PHP via (https://github.com/chrisboulton/php-resque). After going through and finding some workable HA for nginx+php-fpm and MySQL (mysql master-master setup as a way to simply master-slave promotion), next up is Resque+Redis. Standard install of Resque uses localhost Redis (at DigitalOcean). I am heavily depending on Amazon Route 53 DNS failover to try to solve this. resque1.domain.com points to localhost redis (redis1.domain.com) = same server resque2.domain.com points to localhost redis (redis2.domain.com) = same server Do resque.domain.com with FAILOVER resque1 as primary and resque2 as secondary. What this means is that most of the time (99%), resque1 should be getting hit with resque2 as just a hot backup. This lets me just have to get 2 servers and makes sure that any hits to resque.domain.com goes somewhere The other way to do this is to break out resque and redis into 4 servers and do it as follows resque1.domain.com - redis.domain.com resque2.domain.com - redis.domain.com redis1.domain.com redis2.domain.com Then setup DNS Failover resque.domain.com - primary: resque1 and secondary: resque2 redis.domain.com - primary: redis1 and secondary: redis2 I'd like to get away for 2 servers if I can but is this 2nd setup much better or negligible? Thanks, Chris

  • SSL setup: UCC or wildcard certificates?

    - by quanza
    I've scoured the web for a clear and concise answer to my SSL question, but to no avail. So here goes: I have a web-service requiring SSL support for authentication pages. The root-level domain does not have the "www" - i.e., secure://domain.com - but localized pages use "language-code.domain.com", i.e. secure://ja.domain.com So I need at least a wildcard SSL certificate that supports secure://*.domain.com However, we also have a public sandbox environment at sandbox.domain.com, which we also need to support under localized domains - so secure://ja.sandbox.domain.com needs to also work. The previous admin managed to purchase a wildcard SSL certificate for .domain.com, but with a Subject Alternative Name for "domain.com". So, I'm thinking of trying to get a wildcard certificate with SANs defined as "domain.com" and ".*.domain.com". But now I'm getting confused because there seem to be separate SAN certificates, also called UCC certificates. Can someone clarify whether it's possible to get a wildcard certificate with additional SAN fields, and ultimately what the best way is to support: secure://domain.com secure://.domain.com secure://.*.domain.com with the fewest (and cheapest!) number of SSL certificates? Thanks!
