  • static initialization confusion

    - by Happy Mittal
    I am getting very confused in some concepts in c++. For ex: I have following two files //file1.cpp class test { static int s; public: test(){s++;} }; static test t; int test::s=5; //file2.cpp #include<iostream> using namespace std; class test { static int s; public: test(){s++;} static int get() { return s; } }; static test t; int main() { cout<<test::get()<<endl; } Now My question is : 1. How two files link successfully even if they have different class definitions? 2. Are the static member s of two classes related because I get output as 7. Please explain this concept of statics.

  • c# Generics problem

    - by UpTheCreek
    Can anyone tell me why this does not work? I would have thought the constraint would make it valid. public class ClassA<T> where T : ICommon { public ClassA() { ClassB b = new b(); IEnumerable<T> alist = new IList<T>; b.items = alist; //Error: cannot convert from IEnumerable<T> to IEnumerable<ICommon>' } } public class ClassB { IEnumerable<ICommon> items { get; set;} .... }

  • whats a sure shot way to make sure objects appear correctly positioned on stage

    - by dubbeat
    Hi, I've being having a lot of trouble recently getting objects (UIComponents containing movieclips) to appear correctly in the right positions. For example, my current dilema is I have a container that is 3 layers deep. outer layer inner layer display layer This hiearachy was built in CS4 as a movieclip. In the display layer in CS4 I figured out where I want to place 16 different "box" movieclips. I dont want to create these boxes maunually at design time, instead I want to add them at run time. So I know what container I want to add my boxes to. I know what positions they "would" be at in CS4 environment. Whats the best way to add them in the correct locations with code? The "box" I'm trying to add in a movieclip held inside of a UIComponent. Is there a "rule of thumb" to do this type of thing? I'm sure I'm going to encounter this problem again and again and I'd like to just blow the problem out of the water once and for all with the "right way" to do this.

  • python unit testing os.remove fails file system

    - by hwjp
    Am doing a bit of unit testing on a function which attempts to open a new file, but should fail if the file already exists. when the function runs sucessfully, the new file is created, so i want to delete it after every test run, but it doesn't seem to be working: class MyObject_Initialisation(unittest.TestCase): def setUp(self): if os.path.exists(TEMPORARY_FILE_NAME): try: os.remove(TEMPORARY_FILE_NAME) except WindowsError: #TODO: can't figure out how to fix this... #time.sleep(3) #self.setUp() #this just loops forever pass def tearDown(self): self.setUp() any thoughts? The Windows Error thrown seems to suggest the file is in use... could it be that the tests are run in parallel threads? I've read elsewhere that it's 'bad practice' to use the filesystem in unit testing, but really? Surely there's a way around this that doesn't invole dummying the filesystem?

  • Extract Bullets and Tables information in Word doc from c#

    - by Siva
    Hi All, I need to create an word document based on the template in c#. I have tags for only the paragraphs. Is there any way to replace the bullets and tables that are already available in the template based on the user input. I was able to replace the paragraph with input text using the Replace command in the Word InterOp. Need help to do the rest of the items. Replace the bullets based on the user input Fill the tables with the input values Code for replacing the Paragraph based on the tag: FindAndReplace(wordApplication, "/date/", DateTime.Now.Date.ToString("MMM dd, yyyy")); FindAndReplace(){ wordApplication.Selection.Find.Execute(ref findText, ref matchCase, ref matchWholeWord, ref matchWildCards, ref matchSoundsLike, ref matchAllWordsForms, ref forward, ref wrap, ref format, ref replaceWithText, ref replace, ref matchKashida, ref matchDiacritics, ref matchAlefHamsa, ref matchControl); } Thanks in Advance.

  • Hibernate saveOrUpdate fails when I execute it on empty table.

    - by Vladimir
    I'm try to insert or update db record with following code: Category category = new Category(); category.setName('catName'); category.setId(1L); categoryDao.saveOrUpdate(category); When there is a category with id=1 already in database everything works. But if there is no record with id=1 I got following exception: org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1: Here is my Category class setters, getters and constructors ommited for clarity: @Entity public class Category { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; @ManyToOne private Category parent; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") private List<Category> categories = new ArrayList<Category>(); } In the console I see this hibernate query: update Category set name=?, parent_id=? where id=? So looks like hibernates tryis to update record instead of inserting new. What am I doing wrong here?

  • Accessing HttpRequest from Global.asax via a page

    - by Polymorphix
    I'm trying to get a property (ImpersonatePersonId) from a page in global.asax but get a HttpException saying 'Request is not available in this context'. I've been searching for some documentation on where in the pipeline the request is accessible, but as far as I can see all Microsoft can produce of documentation is one-liners like "PostRequestHandlerExecute: Occurs when the ASP.NET event handler finishes execution." which really doesn't give me much... I've tried placing the call in both Pre and PostRequestHandlerExceute but with the same result. I wonder if anyone with experience in this would be so kind as to tell me where the Request object is available. My code from global asax is below. ICanImpersonate page = HttpContext.Current.Handler as ICanImpersonate; ImpersonatedUser impersonatePerson = page != null ? page.ImpersonatePersonId : null; Response.Filter = new TagRewriter(Response, new TagProcessor(Context, impersonatePerson).Process); What I want to do is rewrite some HTML based on some request parameters.

  • Why doesn't the undo/redo panel appear when I start a shake gesture in iPhone Simulator?

    - by dontWatchMyProfile
    I've created an NSUndoManager for the Managed Object Context of Core Data, like this: NSUndoManager *undoManager = [[NSUndoManager alloc] init]; [undoManager setLevelsOfUndo:10]; [managedObjectContext setUndoManager:undoManager]; [undoManager release]; In the app delegate where the didFinishLaunching method is called, I did this: application.applicationSupportsShakeToEdit = YES; For some reason, I never get that undo/redo panel when I make a shake gesture in iPhone Simulator (from the menu). Must I enable undo/redo somewhere else, maybe in the Info.plist file?
