  • Can can I reference extended methods/params without having to cast from the base class object return

    - by Greg
    Hi, Is there away to not have a "cast" the top.First().Value() return to "Node", but rather have it automatically assume this (as opposed to NodeBase), so I then see extended attributes for the class I define in Node? That is is there a way to say: top.Nodes.First().Value.Path; as opposed to now having to go: ((Node)top.Nodes.First().Value).Path) thanks [TestMethod()] public void CreateNoteTest() { var top = new Topology(); Node node = top.CreateNode("a"); node.Path = "testpath"; Assert.AreEqual("testpath", ((Node)top.Nodes.First().Value).Path); // *** HERE *** } class Topology : TopologyBase<string, Node, Relationship> { } class Node : NodeBase<string> { public string Path { get; set; } } public class NodeBase<T> { public T Key { get; set; } public NodeBase() { } public NodeBase(T key) { Key = key; } } public class TopologyBase<TKey, TNode, TRelationship> where TNode : NodeBase<TKey>, new() where TRelationship : RelationshipBase<TKey>, new() { // Properties public Dictionary<TKey, NodeBase<TKey>> Nodes { get; private set; } public List<RelationshipBase<TKey>> Relationships { get; private set; } }

  • How to auto-increment reference number persistently when NSManagedObjects created in core-data.

    - by KayKay
    In my application i am using core-data to store information and saving these data to the server using web-connectivity i have to use MySql. Basically what i want to do is to keep track of number of NSManagedObject already created and Whenever i am adding new NSManagedObject, based on that counting it will assign the class a Int_value which will act as primary_key in MySql. For examaple, there are already 10 NSManagedobjects, and when i will add new one it will assign it "11" as primary_key. these value will have to be increasing because there is no deleting of NSManagedObject. From my approach its about static member in applicationDelegate whose initial value can be any integer but should be incremented by one(like auto-increment) everytime new NSManagedObject is created and also it should be persistent. I am not clear how to do this, please give me suggestions. Thanks in advance.

  • When getting substring in .Net, does the new string reference the same original string data or does

    - by Elan
    Assuming I have the following strings: string str1 = "Hello World!"; string str2 = str1.SubString(6, 5); // "World" I am hoping that in the above example str2 does not copy "World", but simply ends up being a new string that points to the same memory space only that it starts with an offset of 6 and a length of 5. In actuality I am dealing with some potentially very long strings and am interested in how this works behind the scenes for performance reasons. I am not familiar enaugh with IL to look into this.

  • How do I get the ID or reference of the listview row I am clicking a checkbox in?

    - by danielea
    I have an ASP.NET 2.0 ListView control (aka:parent) and configured inside this ListView I have another ListView (aka:child). For each row the parent has there is potentially a child ListView control which can have 1-3 rows. Each row has two checkboxes (a select checkbox and a deny checkbox). I need to process these checkboxes in JavaScript so that if one select is chosen on any of the rows all other select checkboxes are unchecked AND the deny checkbox for that row only is unchecked. The rows which were NOT selected CAN have the deny checkboxes checked. What is the best approach to this?

  • How do I pass a reference type to Control.Invoke / display a form centered on the main form

    - by Rubio
    I'm on a thread other than the UI thread and need to display a modal form that's centered on the application's main form. What I usually do is use the width and height of the main form and the modal form to calculate the location, then use the PointToScreen method of the main form to get the location of the modal form. Since I'm on another thread I need to use Control.Invoke to call this method. I just can't figure out how to pass a parameter of type Point to Control.Invoke (params object[]). Value types and String works fine. Or, if someone can find a better way to display a form centered on the main form regardless of thread, that would be great. MessageBox seems to be able to do this (although not modally).

  • In Objective C, is there a way to call reference a typdef enum from another class?

    - by Adrian Harris Crowne
    It is my understanding that typedef enums are globally scoped, but if I created an enum outside of the @interface of RandomViewController.h, I can't figure out how to access it from OtherViewController.m. Is there a way to do this? So... "RandomViewController.h" #import <UIKit/UIKit.h> typedef enum { EnumOne, EnumTwo }EnumType; @interface RandomViewController : UIViewController { } and then... "OtherViewController.m" -(void) checkArray{ BOOL inArray = [randomViewController checkArray:(EnumType)EnumOne]; }

  • Fluent NHibernate: Entity from one table, but reference will map to another tables?

    - by Andy
    Given the following tables: Product ----------- ProductId : int (PK) ProductVersion : int ProductHistory ----------- ProductId : int (PK) ProductVersion : int (PK) Item ----------- ItemId : int (PK) ProductId : int (FK) -- ProductId + ProductVersion relates to ProductHistory ProductVersion : int (FK) And the following classes: public class Product { } public class Item { public Product Product { get; set; } } What I want to happen is this; we get a Product from the Product table, assign it to Item.Product property. But that Item.Product property should map to ProductHistory. The idea is that only the latest version of a product is in the main Product table, so we allow customers to search against that table (so that if each product has 4 versions and there are 1000 products, we only need to query though 1000 products, not 1000 products * 4 versions of each). Any idea how to acomplish this? Thanks Andy

  • How to organize code using an optional assembly reference?

    - by apoorv020
    I am working on a project and want to optionally use an assembly if available. This assembly is only available on WS 2008 R2, and my ideal product whould be a common binary for both computers with and without the assembly. However, I'm primarily developing on a Windows 7 machine, where I cannot install the assembly. How can I organize my code so that I can (with minimum changes) build my code on a machine without the assembly and secondly, how do I ensure that I call the assembly functions only when it is present. (NOTE : The only use of the optional assembly is to instantiate a class in the library and repeatedly call a (single) function of the class, which returns a boolean. The assembly is fsrmlib, which exposes advanced file system management operations on WS08R2.) I'm currently thinking of writing a wrapper class, which will always return true if the assembly is not present. Is this the right way to go about doing this?

  • Converting Generic Type into reference type after checking its type using GetType(). How ?

    - by Shantanu Gupta
    i am trying to call a function that is defined in a class RFIDeas_Wrapper(dll being used). But when i checked for type of reader and after that i used it to call function it shows me error Cannot convert type T to RFIDeas_Wrapper. EDIT private List<string> GetTagCollection<T>(T Reader) { TagCollection = new List<string>(); if (Reader.GetType() == typeof(RFIDeas_Wrapper)) { ((RFIDeas_Wrapper)Reader).OpenDevice(); // here Reader is of type RFIDeas_Wrapper //, but i m not able to convert Reader into its datatype. string Tag_Id = ((RFIDeas_Wrapper)Reader).TagID(); //Adds Valid Tag Ids into the collection if(Tag_Id!="0") TagCollection.Add(Tag_Id); } else if (Reader.GetType() == typeof(AlienReader)) TagCollection = ((AlienReader)Reader).TagCollection; return TagCollection; } ((RFIDeas_Wrapper)Reader).OpenDevice(); , ((AlienReader)Reader).TagCollection; I want this line to be executed without any issue. As Reader will always be of the type i m specifying. How to make compiler understand the same thing.

  • Close TCP connection when owner process is already killed

    - by Otiel
    I have a Windows service that - when it starts - opens some WCF services to listen on the 8000 port. It happens that this service crashes sometimes. When it does, the TCP connection is not released, thus causing my service to throw an exception if I try to start it again: AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:8000 Some observations: When running CurrPorts or netstat -ano, I can see that the 8000 port is still in use (in LISTENING state) and is owned by the Process ID XXX that corresponded to my service process ID. But my service has already crashed, and does not appear in the Task Manager anymore. Thus I can't kill the process to free the port! Of course, running taskkill /PID XXX returns: ERROR: The process "XXX" not found. When running CurrPorts or netstat -b, I can see that the process name involved in creating the listening port is System, and not as MyService.exe (whereas it is MyService.exe when my service is running). I tried to use CurrPorts to close the connection, but I always get the following error message: Failed to close one or more TCP connections. Be aware that you must run this tool as admin in order to close TCP connections. (Useless to say, I do run CurrPorts as Administrator...) TCPView is not much help either: the process name associated to the 8000 port is <non-existent>, and doing "End process" or "Close connection" has no effect. I tried to see if there was not a child process associated with the PID XXX using Process Explorer, but no luck here. If I close my service properly (before it crashes), the TCP connection is correctly released. This is normal, as I close the WCF service hosts in the OnStop() event of my service. The only way I found to release the connection is to restart the server (which is not convenient in a production environment as you can guess). Waiting does not help, the TCP connection is never released. How can I close the connection without restarting the Windows server? PS: found some questions extremely similar to mine.

  • How do I use Eval() to reference values in a SortedDictionary in an asp Repeater?

    - by MatthewMartin
    I thought I was clever to switch from the memory intensive DataView to SortedDictionary as a memory efficient sortable data structure. Now I have no idea how get the key and value out of the datasource in the <%# or Eval() expressions. SortedDictionary<int, string> data = RetrieveNames(); rCurrentTeam.DataSource = data; rCurrentTeam.DataBind(); <asp:Repeater ID="rNames" runat="server"> <ItemTemplate> <asp:Label ID="lblName" runat="server" Text='<%# Eval("what?") %>' /> </ItemTemplate> </asp:Repeater> Any suggestions?

  • How do you store accented characters coming from a web service into a database?

    - by Thierry Lam
    I have the following word that I fetch via a web service: André From Python, the value looks like: "Andr\u00c3\u00a9". The input is then decoded using json.loads: >>> import json >>> json.loads('{"name":"Andr\\u00c3\\u00a9"}') >>> {u'name': u'Andr\xc3\xa9'} When I store the above in a utf8 MySQL database, the data is stored like the following using Django: SomeObject.objects.create(name=u'Andr\xc3\xa9') Querying the name column from a mysql shell or displaying it in a web page gives: André The web page displays in utf8: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> My database is configured in utf8: mysql> SHOW VARIABLES LIKE 'collation%'; +----------------------+-----------------+ | Variable_name | Value | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database | utf8_unicode_ci | | collation_server | utf8_unicode_ci | +----------------------+-----------------+ 3 rows in set (0.00 sec) mysql> SHOW VARIABLES LIKE 'character_set%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec) How can I retrieve the word André from a web service, store it properly in a database with no data loss and display it on a web page in its original form?

  • Calling services from the Orchestrating layer in SOA?

    - by Martin Lee
    The Service Oriented Architecture Principles site says that Service Composition is an important thing in SOA. But Service Loose Coupling is important as well. Does that mean that the "Orchestrating layer" should be the only one that is allowed to make calls to services in the system? As I understand SOA, the "Orchestrating layer" 'glues' all the services together into one software application. I tried to depict that on Fig.A and Fig.B. The difference between the two is that on Fig.A the application is composed of services and all the logic is done in the "Orchestrating layer" (all calls to services are done from the "Orchestrating layer" only). On Fig.B the application is composed from services, but one service calls another service. Does the architecture on Fig.B violate the "Service Loose Coupling" principle of SOA? Can a service call another service in SOA? And more generally, can the architecture on Fig.A be considered superior to the one on Fig.B in terms of service loose coupling, abstraction, reusability, autonomy, etc.? My guess is that the A architecture is much more universal, but it can add some unnecessary data transfers between the "Orchestrating layer" and all the called services.

  • Why "Finalize method should not reference any other objects" ?

    - by mishal153
    I have been pondering why it is recommended that we should not release managed resources inside finalize. If you see the code example at http://msdn.microsoft.com/en-us/library/system.gc.suppressfinalize.aspx , and search for string "Dispose(bool disposing) executes in two distinct scenarios" and read that comment, you will understand what I mean. Only possibility I can think of is that it probably has something to do with the fact that it is not possible to predict when finalizer will get called. Does anyone know the right answer ? thanks, mishal

  • What is a good 64-bit NASM assembly reference?

    - by Xill
    I have been able to find plenty of 16 and 32-bit NASM assembly references like here, but the only thing I could find on 64-bit NASM was what was in the small section of the NASM manual here. Are there any good sites or books that would have a better explanation of 64-bit assembly (Windows or Linux/Unix) with some good code examples?

  • How can should I set up Flex 3 projects that reference common controls?

    - by Amy
    I'm not a flash developer, I'm having issues figuring out how I should set up these two projects that I have in Flex Builder. I've already created projA which has a .mxml that references several custom controls & skins from com.xxx.controls within projA I now have to build projB which also has a .mxml that will create a different .swf. I want to use some of the same controls from projA I currently build projA through the command line and nant and will need to do the same for projB. Should I create a new project to move all of the common controls into? How do I then use this library project in both the projects & compile via command? Thanks!

  • Access Violation When Accessing an STL Object Through A Pointer or Reference In A Different DLL or E

    - by Yan Cheng CHEOK
    I experience the following problem while using legacy VC6. I just cann't switch to modern compiler, as I am working on a legacy code base. http://support.microsoft.com/kb/172396 Since there are no way to export map, my planned workaround is using static linking instead of dynamic linking. I was wondering whether you all had encountered the similar situation? What is your workaround for this? Another workaround is to create wrapper class around the stl map, to ensure creation and accessing stl map, are within the same DLL space. Note that, fun0, which uses wrapper class will just work fine. fun1 will crash. Here is the code example : // main.cpp. Compiled it as exe. #pragma warning (disable : 4786) #include <map> #include <string> template <class K, class V> class __declspec(dllimport) map_wrapper { public: map_wrapper(); ~map_wrapper(); map_wrapper(const map_wrapper&); map_wrapper& operator=(const map_wrapper&); V& operator[](const K&); const V& operator[](const K&) const; const V& get(const K&) const; void put(const K&, const V&); int size() const; private: std::map<K, V> *m; }; __declspec(dllimport) void fun0(map_wrapper<std::string, int>& m); __declspec(dllimport) void fun1(std::map<std::string, int>& m); int main () { map_wrapper<std::string, int> m0; std::map<std::string, int> m1; m0["hello"] = 888; m1["hello"] = 888; // Safe. The we create std::map and access map both in dll space. fun0(m0); // Crash! The we create std::map in exe space, and access map in dll space. fun1(m1); return 0; } // dll.cpp. Compiled it as dynamic dll. #pragma warning (disable : 4786) #include <map> #include <string> #include <iostream> /* In map_wrapper.h */ template <class K, class V> class __declspec(dllexport) map_wrapper { public: map_wrapper(); ~map_wrapper(); map_wrapper(const map_wrapper&); map_wrapper& operator=(const map_wrapper&); V& operator[](const K&); const V& operator[](const K&) const; const V& get(const K&) const; void put(const K&, const V&); int size() const; private: std::map<K, V> *m; }; /* End */ /* In map_wrapper.cpp */ template <class K, class V> map_wrapper<K, V>::map_wrapper() : m(new std::map<K, V>()) { } template <class K, class V> map_wrapper<K, V>::~map_wrapper() { delete m; } template <class K, class V> map_wrapper<K, V>::map_wrapper(const map_wrapper<K, V>& map) : m(new std::map<K, V>(*(map.m))) { } template <class K, class V> map_wrapper<K, V>& map_wrapper<K, V>::operator=(const map_wrapper<K, V>& map) { std::map<K, V>* tmp = this->m; this->m = new std::map<K, V>(*(map.m)); delete tmp; return *this; } template <class K, class V> V& map_wrapper<K, V>::operator[](const K& key) { return (*this->m)[key]; } template <class K, class V> const V& map_wrapper<K, V>::operator[](const K& key) const { return (*this->m)[key]; } template <class K, class V> const V& map_wrapper<K, V>::get(const K& key) const { return (*this->m)[key]; } template <class K, class V> void map_wrapper<K, V>::put(const K& key, const V& value) { (*this->m)[key] = value; } template <class K, class V> int map_wrapper<K, V>::size() const { return this->m->size(); } // See : http://www.parashift.com/c++-faq-lite/templates.html#faq-35.15 // [35.15] How can I avoid linker errors with my template classes? template class __declspec(dllexport) map_wrapper<std::string, int>; /* End */ __declspec(dllexport) void fun0(map_wrapper<std::string, int>& m) { std::cout << m["hello"] << std::endl; } __declspec(dllexport) void fun1(std::map<std::string, int>& m) { std::cout << m["hello"] << std::endl; }

  • What is the correct way to reference RDFa namespaces in HTML5?

    - by Eivind Eidheim Elseth
    I'm setting up a HTML5 webpage and want to include RDFa. I try checking the syntax with the w3 validator, and check the extracted RDF using the w3 RDFa distiller. When I declare namespaces using xmlns:<ns>="<uri>" the validator complains that the attribute is not allowed there, and the specs say that xmlns is deprecated, but if I try the other suggested prefix="<ns> <uri>" the distiller doesn't discover the RDFa embedded on my page. Which way should I stick to?

  • Why isn't my Ruby object deleted when the last reference goes out of scope?

    - by Andrew Clegg
    Hi gurus, I've found a weird effect when trying to track down a memory leak in a Rails app. Can anyone explain what's going on here? Save this script as a plain Ruby script (Rails not necessary): class Fnord def to_s 'fnord' end end def test f = Fnord.new end test GC.start sleep 2 ObjectSpace.each_object do |o| puts o if o.is_a? Fnord end When I run this via ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] I get the following: bash $ ruby var_test fnord Although the variable f is out of scope, there are no other references to the single Fnord object, and I've garbage collected, the object still seems to exist. Is this a nefarious memory leak of some sort, or am I completely missing something about Ruby? Further, if I change the test method to this: def test f = Fnord.new f = nil end I get no output. But surely this should not change the semantics here? Many thanks!

  • What are good strategies for organizing single class per query service layer?

    - by KallDrexx
    Right now my Asp.net MVC application is structured as Controller - Services - Repositories. The services consist of aggregate root classes that contain methods. Each method is a specific operation that gets performed, such as retrieving a list of projects, adding a new project, or searching for a project etc. The problem with this is that my service classes are becoming really fat with a lot of methods. As of right now I am separating methods out into categories separated by #region tags, but this is quickly becoming out of control. I can definitely see it becoming hard to determine what functionality already exists and where modifications need to go. Since each method in the service classes are isolated and don't really interact with each other, they really could be more stand alone. After reading some articles, such as this, I am thinking of following the single query per class model, as it seems like a more organized solution. Instead of trying to figure out what class and method you need to call to perform an operation, you just have to figure out the class. My only reservation with the single query per class method is that I need some way to organize the 50+ classes I will end up with. Does anyone have any suggestions for strategies to best organize this type of pattern?
