  • How can I spoof a jndi lookup for a datasource without a app server

    - by Wiszh
    I want to test some new functionality which is part of an internal web app. This new code uses a database connection normally provided by an app server (tomcat). I do not want to recreate the entire web app on my local machine to test the new code, since I only need to run one function. Does anyone know how I can 'spoof' a Context, or Datasource, to retrieve the database config, without actually creating a web app instance on a server? Thanks

  • How to dispose of a NET COM interop object on Release()

    - by mhenry1384
    I have a COM object written in managed code (C++/CLI). I am using that object in standard C++. How do I force my COM object's destructor to be called immediately when the COM object is released? If that's not possible, call I have Release() call a MyDispose() method on my COM object? My code to declare the object (C++/CLI): [Guid("57ED5388-blahblah")] [InterfaceType(ComInterfaceType::InterfaceIsIDispatch)] [ComVisible(true)] public interface class IFoo { void Doit(); }; [Guid("417E5293-blahblah")] [ClassInterface(ClassInterfaceType::None)] [ComVisible(true)] public ref class Foo : IFoo { public: void MyDispose(); ~Foo() {MyDispose();} // This is never called !Foo() {MyDispose();} // This is called by the garbage collector. virtual ULONG Release() {MyDispose();} // This is never called virtual void Doit(); }; My code to use the object (native C++): #import "..\\Debug\\Foo.tlb" ... Bar::IFoo setup(__uuidof(Bar::Foo)); // This object comes from the .tlb. setup.Doit(); setup-Release(); // explicit release, not really necessary since Bar::IFoo's destructor will call Release(). If I put a destructor method on my COM object, it is never called. If I put a finalizer method, it is called when the garbage collector gets around to it. If I explicitly call my Release() override it is never called. I would really like it so that when my native Bar::IFoo object goes out of scope it automatically calls my .NET object's dispose code. I would think I could do it by overriding the Release(), and if the object count = 0 then call MyDispose(). But apparently I'm not overriding Release() correctly because my Release() method is never called. Obviously, I can make this happen by putting my MyDispose() method in the interface and requiring the people using my object to call MyDispose() before Release(), but it would be slicker if Release() just cleaned up the object. Is it possible to force the .NET COM object's destructor, or some other method, to be called immediately when a COM object is released? Googling on this issue gets me a lot of hits telling me to call System.Runtime.InteropServices.Marshal.ReleaseComObject(), but of course, that's how you tell .NET to release a COM object. I want COM Release() to Dispose of a .NET object.

  • What is a best free way to make form resizeable in Delphi 7?

    - by Tofig Hasanov
    I need my form in Delphi to be resizeable, and all components and controls should stretch proportionally, along with font sizes etc. Right now in order to resize components I write a code inside "OnResize" event, and manually calculate all components' sizes and fonts. I would like to have more simple solution, which I can apply to different applications without rewriting this code for each form. I found some components on the web, but they are shareware. Can you suggest something?

  • Why isn't JML implemented as Annotations in Java?

    - by devoured elysium
    Contrary to Code Contracts in C#, in JML Code Contracts are just text that's used in the form of comments in the header of a method. Wouldn't it be better to have them exposed as Annotations, then? That way even when compiling the information would persist on the .class's metadata, contrary to comments, that get erased. Am I missing something? Thanks

  • How do I print out objects in an array in python?

    - by Jonathan
    I'm writing a code which performs a k-means clustering on a set of data. I'm actually using the code from a book called collective intelligence by O'Reilly.

  • How can I obtain a list of modified files within a 'changeset' range from team foundation server thr

    - by Colin W
    I'm trying to create a tool which will help my team perform code reviews on a more regular basis without it's usual massive overhead. At the moment the manual process involves using Team Foundation Sidekicks to identify the Changesets and then exporting that to excel to filter the results to find which items need to be reviewed (e.g. code files). I've heard mention of using a TFS API, but found very little help online possibly because I was asking google 'the wrong questions'.
