I need a good reference for how to use standard Libraries in Ruby. What confuses me about current libraries is that they don't describe or give examples like say Java's. Yet this is where examples are much more needed (in Ruby), because I am not familiar with how the called method will yield! So I am left with having to look at the sourc...
I have recently re-organised our source control and found one of our solutions no longer builds. The only error that we get is: Error 65 Unknown build error, 'The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 ch...
Hello my StackOverflow friends. I have been doing wxPython tutorials and reading the documentation, so far I like it. I wanted to make a simple app first. What this app would do is send a command to a micro controller to turn a relay on or off. I have a global variable to get the COM port to be used (Instead of hardcoding COM1 in for...
I am working on an .NET library project, containing a bunch of interfaces which can be consumed by a service, which I am also creating. Users of the service will provide implementations of the interfaces from the library, which are then injected into the service application. My library relies on a third-party library, which I will of co...
I wanted to add System.Data.Linq to my Silverlight 3.0 app, but the only references that are available to me are listed as version 2.0.50727 or lower. Shouldn't I have access to more than that? In my project's properties, my Target Silverlight Version is set to "Silverlight 3.0" (the only option), and I'm using Visual Studio 2010 Beta 2...
Hey folks, I've got an ASP.NET web site project that for some reason is insisting on referencing both mscorlib 1.0.5 and mscorlib 2.0, and I can't figure out why. I've analyzed all the referenced DLLs using NDepend, and they all appear to only reference mscorlib 2.0. I've got a couple web references, but I can't imagine why that would c...
I am working on a project that consists of several ESB Applications deployed on a JBoss Application Server. Each ESB Application processes messages (validate, enrich...) through several actions (they extend AbstractActionLifecycle); Some of those actions are identical for all applications. To avoid code duplication I moved all actio...
[SOLVED] - The mistake was mine, that I didn't link World (world_) to the entity, so that was null. Thanks for the explanation everyone! As you may know by now, I'm making a game engine/framework, and I've got stuck linking stuff with references to each other. Example: public void Attach(Entity Entity) { entity_ = Entity; en...
Pointers-to-pointers and references-to-pointers seem overly complicated at first, especially for newbies. What is the best and most useful reason you used one in a c/c++ project you worked on? This can help people better understand pointers and how to use them effectively. Edited: Included C as well as C++ ...
I've came across the following code, ok, not exactly but close. The point of interest is the second line in the (heavily abbreviated code). Why does one have to intialize someReference 'someReference' ? Other then be able to use . operator instead of -> ? ptrThis is just as good, no? (it's inside the thread method, if that makes any diff...
I'm writing a Clone function for a non serializeable object.For most objects I don't care if they are shallow copied as I won't be making any changes to them. I start with a MemberwiseClone and this copies all the values and few objects like configuration dictionary over just fine but they are pointers. EAVEntity newClone = (EAVEntity...
Suppose I have a class class Foo { public: ~Foo() { delete &_bar; } void SetBar(const Bar& bar) { _bar = bar; } const Bar& GetBar() { return _bar; } private: Bar& _bar; } And my usage of this class is as follows (assume Bar has a working copy constructor) Foo f; f.SetBar(*(new Bar)); const Bar* bar =...
I've tried to do that. HasManyToMany<YechidotDoarInGroup>(x => x.Col_yig) .Table("PigToYig") .ChildKeyColumn("YIG_GROUP_RECID") .ParentKeyColumn("PIG_GROUP_RECID"); but I've got ORA-00942: table or view does not exist I am trying to establish HasManyToMany conn...
I'm trying to design a simple cache that follows the following rules: Entries have a unique key When the number of entries in the cache exceeds a certain limit, the older items are evicted (to keep the cache from getting too large). Each entry's data is immutable until the entry is removed from the cache. A 'reader' can access an entry...
Hi, I am using two classes in my C++ application. The code is as follows: class MyMessageBox { public: void sendMessage(Message *msg, User *recvr); Message receiveMessage(); list<Message> dataMessageList; }; class User { public: MyMessageBox *dataMsgBox; }; The msg is a pointer to a derived class object of Message cl...
In C++ a pointer is a pointer to an address of memory where another variable is stored and in C# a reference is some how same. What is the difference between these two? ...
Hi there, I just stumbled upon something i don't quite understand. I know that variables in ruby are references. So that awesome stuff is possible. But when i pass a variable to a method, it behaves strangely: my_var_a = "nothing happend to me" my_var_b = "nothing happend to me" def parse_set(my_var_set) my_var_set = "my value chang...
The way I understand it, SSIS script tasks can't use a reference unless it's in the GAC. With this assumption: I've tried downloading the .net 2.0 sdk x64 (developing on 64 bit machine) that should have gacutil, still not there. I've tried installing the dll using a console app using the System.EnterpriseServices.Internal.Publish.Ga...
For some reason ss.transition() does not affect the appropriate DOM elements after ss.goTo() is triggered by an onclick. The ss.transition() call under //Init does work as expected. I assume this is a scope problem. Little help? var ss = {}; ss.goTo = function(i) { ss.old = ss.current; ss.current = ss.slides[i]; ss.transiti...
Possible Duplicate: Why this is a pointer and not a reference? Are there use-cases that I'm missing that make "this" as a pointer more useful than a reference? If not, are there any language design implications/considerations involved in having it as a pointer? Thank you. ...
