  • C#/Resharper 5 structural search, detect and warn if any non-virtual public methods on classes with

    - by chillitom
    Hi All, I'm using LinFu's dynamic proxy to add some advice to some classes. The problem is that the proxied objects can only intercept virtual methods and will return the return type's default value for non-virtual methods. I can tell whether a class is proxied or not based whether the class or any of it's method has an interception attribute, e.g. [Transaction] Is it possible to write a ReSharper 5 structural search that would warn if any non-virtual public methods are defined on a class with an interception attribute. E.g. Ok public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public virtual void AnotherMethod() { ... } } Bad public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public void AnotherMethod() // non-virtual method will not be called by proxy { ... } } Many Thanks.

  • Django foreign keys cascade deleting and "related_name" parameter (bug?)

    - by Wiseman
    In this topic I found a good way to prevent cascade deleting of relating objects, when it's not neccessary. class Factures(models.Model): idFacture = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Paiements(models.Model): idPaiement = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Lettrage(models.Model): idLettrage = models.IntegerField(primary_key=True) def delete(self): """Dettaches factures and paiements from current lettre before deleting""" self.factures_set.clear() self.paiements_set.clear() super(Lettrage, self).delete() But this method seems to fail when we are using ForeignKey field with "related_name" parameter. As it seems to me, "clear()" method works fine and saves the instance of "deassociated" object. But then, while deleting, django uses another memorized copy of this very object and since it's still associated with object we are trying to delete - whooooosh! ...bye-bye to relatives :) Database was arcitectured before me, and in somewhat odd way, so I can't escape these "related_names" in reasonable amount of time. Anybody heard about workaround for such a trouble?

  • Automate Testing on future only items business rules

    - by Titan
    I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

  • How can I limit access to a particular class to one caller at a time in an ASMX web service?

    - by MusiGenesis
    I have a web service method in which I create a particular type of object, use it for a few seconds, and then dispose it. Because of problems arising from multiple threads creating and using instances of this class at the same time, I need to restrict the method so that only one caller at a time ever has one of these objects. To do this, I am creating a private static object: private static object _lock = new object(); ... and then inside the web service method I do this around the critical code: lock (_lock) { using (DangerousObject do = new DangerousObject()) { do.MakeABigMess(); do.CleanItUp(); } } I'm not sure this is working, though. Do I have this right? Will this code ensure that only one instance of DangerousObject is instantiated and in use at a time? Or does each caller get their own copy of _lock, rendering my code here laughable?

  • How to add a property to a module in boost::python?

    - by Checkers
    You can add a property to a class using a getter and a setter (in a simplistic case): class<X>("X") .add_property("foo", &X::get_foo, &X::set_foo); But how to add a property to a module itself (not a class)? There is scope().attr("globalAttr") = ??? something ??? and def("globalAttr", ??? something ???); I can add global functions and objects of my class using the above two ways, but can't seem to add properties the same way as in classes.

  • How do I convert PDF to HTML programmatically?

    - by SoaperGEM
    Are there any classes, COM objects, command line utilities, or anything else that I can make an API for that can convert a PDF to an HTML document? Obviously the conversion might be a little rough since PDFs can contain a lot more than HTML can describe. I found a utility called pdftohtml on Source Forge, but quite honestly it does a horrible job with the conversion. I don't care if the software is free or commercial, but is there anything out there at all that I can incorporate with my own software to do this sort of conversion at least decently? I know Google's developed their own method of doing this, since you can click "View as HTML" on a PDF attached to an email through Gmail, but I was hoping there was something out available to the public. Remember, PDF to HTML. I'm NOT worried about HTML to PDF.

  • Passing empty list as parameter to JPA query throws error

    - by Tuukka Mustonen
    If I pass an empty list into a JPA query, I get an error. For example: List<Municipality> municipalities = myDao.findAll(); // returns empty list em.createQuery("SELECT p FROM Profile p JOIN p.municipality m WHERE m IN (:municipalities)") .setParameter("municipalities", municipalities) .getResultList(); Because the list is empty, Hibernate generates this in SQL as "IN ()", which gives me error with Hypersonic database. There is a ticket for this in Hibernate issue tracking but there are not many comments/activity there. I don't know about support in other ORM products or in JPA spec either. I don't like the idea of having to manually check for null objects and empty lists every time. Is there some commonly known approach/extension to this? How do you handle these situations?

  • XNA popup text dialog

    - by mazzzzz
    Hey guys, I am working on a game, and wanted to add a screen that would open when the user clicked on certain objects. The screen would be laid out to have an image on the left, a title on the top right, and text below the title. I have a few problems with this, 1) How would I create the popup box? (preferably with rounded edges) 2) How would I wrap the text (in front of the picture, but not outside the popup-box, I may even need vertical scroll bars) 3) How would I account for different screen resolutions (would they even make a difference?) Thanks for any and all help, Max

    My xml document reflects an Object. as referential Recursion is possible in objects and arrays. I need to reflect that in reproduced XML Structure too. Currently I am using Unique IDs to identify each node separately and a node like <recursion refer="IDREF"> and specifying the ID of the referenced Element. But in This way I need My Own Custom XPath resolver cause I want to let the users go deeper into the recursive node through the Identifying IDREF (Hope I am able to make you understand). So is there any better/liteweight solution ?? might be XPointer or XLink (I am not sure). Any help ??

  • Call function under object from string

    - by sam
    I have a script which creates a drag-and-drop uploader on the page from a div. My DIV will look something like <div class="well uploader" data-type="image" data-callback="product.addimage" data-multi="1"></div> Then I'll have a function something like var product = new function(){ /* Some random stuff */ this.addimage = function(image){ alert('W00T! I HAZ AN IMAGE!'); } /* More random stuff */ } When the upload is complete, I need to call the function in data-callback (In this example, product.addimage). I know with global functions you can just do window[callback]() but I'm not sure the best way to do this with functions under objects. My first thought was to do something like* var obj = window; var parts = callback.split('.'); for(part in parts){ obj = obj[parts[part]]; } obj(); but that seems a bit dirty, is there a better way without using eval because eval is evil? I haven't tested this so I have no idea if it will work

  • How to add text to path?

    - by Pritorian
    Hi all. Te question is how to add text to path element. For example, I have path: Path firstPath = new Path(); firstPath.Stroke = Brushes.Black; firstPath.StrokeThickness = 1; myCanvas.Children.Add(firstPath); LineGeometry firstLine = new LineGeometry(); firstPath.Data = firstLine; And somewhere I define line's Start and End point's. The path is binded to controls (for example - two ellipses) and when I drag one of them, the line is dynamically resized and moved to be pinned to both objects. And now I wand to add some text, that would fit to this line and follow it. Any recommendations how to do this?

  • Global Timer in Javascript with Multiple Callbacks

    - by Mike Beepo
    I want to create a global timer object in javascript and then be able to add callbacks to it on the fly. This way I can just use one global timer in my script to execute all actions at a certain interval rather than wasting resources by using multiples. This is how I want to be able to piece things together: var timer = new function() { clearInterval( this.interval ); //[1] At this point I want the Callbacks to be run var self = this; setTimeout(function() {self.timer()}, 200); } function otherObject = new function() { //When created I want to bind my object's function called cb to the global timer at [1] } otherObject.prototype.cb = function() { //Stuff that should be done every time the timer is run } var someObject = new otherObject(); How would I make it possible bind any number functions (most of which are functions within other objects) to run at the interval of my timer on the fly?

  • Simple object creation with DIY-DI?

    - by Runcible
    I recently ran across this great article by Chad Perry entitled "DIY-DI" or "Do-It-Yourself Dependency Injection". I'm in a position where I'm not yet ready to use a IoC framework, but I want to head in that direction. It seems like DIY-DI is a good first step. However, after reading the article, I'm still a little confused about object creation. Here's a simple example: Using manual constructor dependency injection (not DIY-DI), this is how one must construct a Hotel object: PowerGrid powerGrid; // only one in the entire application WaterSupply waterSupply; // only one in the entire application Staff staff; Rooms rooms; Hotel hotel(staff, rooms, powerGrid, waterSupply); Creating all of these dependency objects makes it difficult to construct the Hotel object in isolation, which means that writing unit tests for Hotel will be difficult. Does using DIY-DI make it easier? What advantage does DIY-DI provide over manual constructor dependency injection?

  • WPF Visual States and the transitions between them

    - by Mark
    I'm trying to define many different states in my app (around 7 in my case) and I have defined each one of them with a "Default Transition" of zero seconds, but the animation that accompanies each state goes for 1 second. When I fire up my app I have a button than goes through the states one by one, when I go "State1" - "State2" it looks perfect, but when I tell my app (which should be in State2 now) to go to "State3" it reverts all the objects in my scene back to their base state, and then animates to "State3", why doesnt it go from "State2" to "State3". I was hoping to only define each state's end position without defining a starting position as this would really take a long time to do. Can this be done? Any examples? Cheers, Mark

  • Exporting info from PS script to csv

    - by George
    Hi, This is a powershell/AD/Exchange question.... I'm running a script against a number of Users to check some of their attributes however I'm having trouble getting this to output to CSV. The script runs well and does exactly what I need it to do, the output on screen is fine, I'm just having trouble getting it to directly export to csv. The input is a comma seperated txt file of usernames (eg "username1,username2,username3") I've experimented with creating custom ps objects, adding to them and then exporting those but its not working.... Any suggestions gratefully received.. Thanks George $array = Get-Content $InputPath #split the comma delimited string into an array $arrayb = $array.Split(","); foreach ($User in $arrayb) { #find group memebership Write-Host "AD group membership for $User" Get-QADMemberOf $User #Get Mailbox Info Write-Host "Mailbox info for $User" Get-Mailbox $User | select ServerName, Database, EmailAddresses, PrimarySmtpAddress, WindowsEmailAddress #get profile details Write-Host "Home drive info for $User" Get-QADUser $User| select HomeDirectory,HomeDrive #add space between users Write-Host "" Write-Host "******************************************************" } Write-Host "End Script"

  • Memory leak - debugger and memory analyzer disagreeing

    - by Joe
    There is a memory leak in my android game - I've managed to narrow it down to a certain object, which has a list of objects to render on a texture. This object clears the list every time it draws though - so I can't work out how its managed to get thousands of elements in the list. I checked in the debugger and it doesn't have all these thousands of elements - usually about 2-20 which is what I'd expect... The game definitely slows down progressively only if I have rendering to texturing on. Here is a picture of Memory Analyzer showing 6,111 items: Memory Analyzer Here is a picture of the debugger showing 2: Debugger Can anyone help me find out whats wrong?

  • Accessing a dictionary value by custom object value in Python?

    - by Sam
    So I have a square that's made up of a series of points. At every point there is a corresponding value. What I want to do is build a dictionary like this: class Point: def __init__(self, x, y): self._x = x self._y = y square = {} for x in range(0, 5): for y in range(0, 5): point = Point(x,y) square[point] = None However, if I later create a new point object and try to access the value of the dictionary with the key of that point it doesn't work.. square[Point(2,2)] Traceback (most recent call last): File "<pyshell#19>", line 1, in <module> square[Point(2,2)] KeyError: <__main__.Point instance at 0x02E6C378> I'm guessing that this is because python doesn't consider two objects with the same properties to be the same object? Is there any way around this? Thanks

  • How does this ruby custom accessor work

    - by ennuikiller
    So the method below in class_eval dynamically creates accessors for attributes defined at runtime. It can be used, for example, to create configuration objects with attributes read from a config file (and unknown until runtime). I understanding all of it except for the else branch. If I am correct the else branch returns the attribute value (val[0]) if there is one value passed in *val. However the way its written I would expect it to return an array (val) if there is more then one value passed in *var. In particular, if I have something like the following: value = 5 then from reading the code I would expect "#{@value}" to be [=,5]. However "#{@value}" returns 5 and not the array [=,5]. How is this possible? class Module def dsl_accessor(*symbols) symbols.each do |sym| class_eval %{ def #{sym}(*val) if val.empty? @#{sym} else @#{sym} = val.size == 1 ? val[0] : val end end } end end end

  • Is there a faster alternative to using textures in XNA?

    - by Matthew Bowen
    I am writing a map editing program for a 2D game using XNA. To create a Texture2D for all of the tiles that a map requires takes too long. Are there any alternatives to using textures for drawing with XNA? I attempted to create just one texture per tile set instead of a texture for every tile in a tile set, but there is a limit to the size of textures and I could not fit all the tiles of a tile set into one texture. Currently the program contains all the would-be textures in memory as Bitmap objects. Is there a way to simply draw a Bitmap object to the screen in XNA? I have searched but I cannot find any information on this. This approach would avoid having to create textures altogether, however any tinting or effects I would have to do to the bitmap directly. Any help would be very much appreciated. Thanks

  • How to print non-ASCII characters in Python

    - by Roman
    I have a problem when I'm printing (or writing to a file) the non-ASCII characters in Python. I've resolved it by overriding the str method in my own objects, and making "x.encode('utf-8')" inside it, where x is a property inside the object. But, if I receive a third-party object, and I make "str(object)", and this object has a non-ASCII character inside, it will fail. So the question is: is there any way to tell the str method that the object has an UTF-8 codification, generically? I'm working with Python 2.5.4.

  • Using TortoiseHg to push to an authenticated git repository

    - by Nathan Palmer
    I'm trying to push a changeset from a local Mercurial repository created with TortoiseHg to a remote Git repository. I have hg-git installed and configured and it will pull just fine. But when I run the push it gives me this Command hg push git+ssh://git@dummyrepo:username/repo.git Result pushing to git+ssh://git@dummyrepo:username/repo.git importing Hg objects into Git creating and sending data abort: the remote end hung up unexpectedly There are several things I've done to get to this point. But I'm hoping to resolve this last thing because I find TortoiseHg to be much easier to work with than any of the Git tools out there (for windows.) Installed TortoiseHg Pulled down the hg-git from http://bitbucket.org/durin42/hg-git/ Configured mercurial.ini to point to the hg-git library Pulled down dulwich source from git://git.samba.org/jelmer/dulwich.git Compiled dulwich and put it into library.zip for TortoiseHg Configured TortoiseHg to use TortoisePlink.exe for ssh Added my private key to Pageant Any ideas what I could be missing?

  • MVC DateTime binding with incorrect date format

    - by Sam Wessel
    Asp.net-MVC now allows for implicit binding of DateTime objects. I have an action along the lines of public ActionResult DoSomething(DateTime startDate) { ... } This successfully converts a string from an ajax call into a DateTime. However, we use the date format dd/MM/yyyy; MVC is converting to MM/dd/yyyy. For example, submitting a call to the action with a string '09/02/2009' results in a DateTime of '02/09/2009 00:00:00', or September 2nd in our local settings. I don't want to roll my own model binder for the sake of a date format. But it seems needless to have to change the action to accept a string and then use DateTime.Parse if MVC is capable of doing this for me. Is there any way to alter the date format used in the default model binder for DateTime? Shouldn't the default model binder use your localisation settings anyway?
