  • creating proxy object in groovy

    - by IttayD
    Hi, I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor: def p = toProxy(1) assert p == 1 assert p * 2 == 2 assert p.underlying == 1 def p2 = toProxy(objWithMethodFoo) p2.foo() p2.underlying.foo() I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.

  • Is there a way to check if a var is using setInterval() ?

    - by chadley
    For instance, I am setting an interval like timer = setInterval(fncName, 1000); and if i go and do clearInterval(timer); it does clear the interval but is there a way to check that it cleared the interval? I've tried getting the value of it while it has an interval and when it doesn't but they both just seem to be numbers.

  • Need one login for two different sites

    - by Eric
    I am tasked to create a web site using Django. It will be a 'sister' site to an existing Plone site. The same Apache instance will be the front end to the sites which allows me to use the same domain name. However, the owners want the users to be able to log into one and still be logged into the other one. How can this be accomplished? Thanks! :)

  • Auto add magnifying icon to thumbnails

    - by Jason
    Hi, I'm looking to add a centered magnifying glass icon to my portfolio gallery. Like the effect at http://jquerystyle.com/gallery. I know I can do this with css at each instance, but I would like to find a way to do it automatically. Any jquery plugins that do this? Thanks!

  • MS Access Dropdown List/Combo Box

    - by noblethrasher
    This should probably be pretty simple but my Google-Fu is as yet unable to find an answer. I simply want to create a dropdown list in Access so that upon selection I can perform some action based on the value of the selection. For instance, I have a list of people and I would like to populate the combo box so that their names appear in the list but the "value" is set to their ID (the primary key).

  • Extending a Java Swing class in Clojure

    - by mikera
    I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods. I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances. What's the recommended way of doing this?

  • VB.Net calling New without assigning value

    - by dcp
    In C# I can do this: new SomeObjectType("abc", 10); In other words, I can call new without assigning the created instance to any variable. However, in VB.Net it seems I cannot do the same thing. New SomeObjectType("abc", 10) ' syntax error Is there a way to do this in VB.Net?

  • Methods in Ruby: objects or not?

    - by Mladen Jablanovic
    Inspired by this discussion, after some googling I wasn't able to find an answer to a pretty simple question regarding methods in Ruby: are they objects or not? There are different opinions here and there, and I would really like to hear, let's say, an in-depth explanation. I'm aware of Object#method method, which takes a method name and returns a Method instance, but, on the other hand, there's a similar thing you can do with blocks to make them into Proc instances, and blocks aren't objects, so what makes methods any different?

  • Create a class that inherets DrawableGameComponent in XNA as a CLASS with custom functions

    - by user3675013
    using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Media; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; namespace TileEngine { class Renderer : DrawableGameComponent { public Renderer(Game game) : base(game) { } SpriteBatch spriteBatch ; protected override void LoadContent() { base.LoadContent(); } public override void Draw(GameTime gameTime) { base.Draw(gameTime); } public override void Update(GameTime gameTime) { base.Update(gameTime); } public override void Initialize() { base.Initialize(); } public RenderTarget2D new_texture(int width, int height) { Texture2D TEX = new Texture2D(GraphicsDevice, width, height); //create the texture to render to RenderTarget2D Mine = new RenderTarget2D(GraphicsDevice, width, height); GraphicsDevice.SetRenderTarget(Mine); //set the render device to the reference provided //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. return Mine; //I'm hoping that this returns the same instance and not a copy. } public void draw_texture(int width, int height, RenderTarget2D Mine) { GraphicsDevice.SetRenderTarget(null); //Set the renderer to render to the backbuffer again Rectangle drawrect = new Rectangle(0, 0, width, height); //Set the rendering size to what we want spriteBatch.Begin(); //This uses spritebatch to draw the texture directly to the screen spriteBatch.Draw(Mine, drawrect, Color.White); //This uses the color white spriteBatch.End(); //ends the spritebatch //Call base.draw after this since it doesn't seem to recognize inside the function //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. } } } I solved a previous issue where I wasn't allowed to access GraphicsDevice outside the main Default 'main' class Ie "Game" or "Game1" etc. Now I have a new issue. FYi no one told me that it would be possible to use GraphicsDevice References to cause it to not be null by using the drawable class. (hopefully after this last bug is solved it doesn't still return null) Anyways at present the problem is that I can't seem to get it to initialize as an instance in my main program. Ie Renderer tileClipping; and I'm unable to use it such as it is to be noted i haven't even gotten to testing these two steps below but before it compiled but when those functions of this class were called it complained that it can't render to a null device. Which meant that the device wasn't being initialized. I had no idea why. It took me hours to google this. I finally figured out the words I needed.. which were "do my rendering in XNA in a seperate class" now I haven't used the addcomponent function because I don't want it to only run these functions automatically and I want to be able to call the custom ones. In a nutshell what I want is: *access to rendering targets and graphics device OUTSIDE default class *passing of Rendertarget2D (which contain textures and textures should automatically be passed with a rendering target? ) *the device should be passed to this function as well OR the device should be passed to this function as a byproduct of passing the rendertarget (which is automatically associated with the render device it was given originally) *I'm assuming I'm dealing with abstracted pointers here so when I pass a class object or instance, I should be recieving the SAME object , I referenced, and not a copy that has only the lifespan of the function running. *the purpose for all these options: I want to initialize new 2d textures on the fly to customize tileclipping and even the X , y Offsets of where a WHOLE texture will be rendered, and the X and Y offsets of where tiles will be rendered ON that surface. This is why. And I'll be doing region based lighting effects per tile or even per 8X8 pixel spaces.. we'll see I'll also be doing sprite rotations on the whole texture then copying it again to a circular masked texture, and then doing a second copy for only solid tiles for masked rotated collisions on sprites. I'll be checking the masked pixels for my collision, and using raycasting possibly to check for collisions on those areas. The sprite will stay in the center, when this rotation happens. Here is a detailed diagram: http://i.stack.imgur.com/INf9K.gif I'll be using texture2D for steps 4-6 I suppose for steps 1 as well. Now ontop of that, the clipping size (IE the sqaure rendered) will be able to be shrunk or increased, on a per frame basis Therefore I can't use the same static size for my main texture2d and I can't use just the backbuffer Or we get the annoying flicker. Also I will have multiple instances of the renderer class so that I can freely pass textures around as if they are playing cards (in a sense) layering them ontop of eachother, cropping them how i want and such. and then using spritebatch to simply draw them at the locations I want. Hopefully this makes sense, and yes I will be planning on using alpha blending but only after all tiles have been drawn.. The masked collision is important and Yes I am avoiding using math on the tile rendering and instead resorting to image manipulation in video memory which is WHY I need this to work the way I'm intending it to work and not in the default way that XNA seems to handle graphics. Thanks to anyone willing to help. I hate the code form offered, because then I have to rely on static presence of an update function. What if I want to kill that update function or that object, but have it in memory, but just have it temporarily inactive? I'm making the assumption here the update function of one of these gamecomponents is automatic ? Anyways this is as detailed as I can make this post hopefully someone can help me solve the issue. Instead of tell me "derrr don't do it this wayyy" which is what a few people told me (but they don't understand the actual goal I have in mind) I'm trying to create basically a library where I can copy images freely no matter the size, i just have to specify the size in the function then as long as a reference to that object exists it should be kept alive? right? :/ anyways.. Anything else? I Don't know. I understand object oriented coding but I don't understand this XNA It's beggining to feel impossible to do anything custom in it without putting ALL my rendering code into the draw function of the main class tileClipping.new_texture(GraphicsDevice, width, height) tileClipping.Draw_texture(...)

  • Forward DB requests after a DB move in SQL Server

    - by Nissan Fan
    I've moved database from one SQL Server instance on a machine to another machine completely. Is there any way to forward requests to the new server automatically so it doesn't require client config changes? Keep in mind it's only one DB out of many on the original server so I can't just forward all requests.

  • binlog_format = STATEMENT and CURRENT_TIMESTAMP with MySQL replication

    - by xma
    Hi, can a MySQL slave instance have different row values for the same ID when binlog_format is set to STATEMENT and we insert something like: insert into foo values(CURRENT_TIMESTAMP) As I understand it, the slave read the SQL statement and execute it thus, if the replication is lagging, could lead to differences for the same row. Right or wrong ? How can I avoid this situation ? Thank you.

  • how can protected members of base class be accessed during unit test?

    - by amateur
    I am creating a unit test in mstest with rhino mocks. I have a class A that inherits class B. I am testing class A and create an instance of it for my test. The class it inherits, "B", has some protected methods and protected properties that I would like to access for the benefit of my tests. For example, validate that a protected property on my base class has the expected value. Any ideas how I might access these protected properties of class B during my test?

  • What does CPU Time consist of? [closed]

    - by Sid
    What does CPU time exactly consist of? For instance, is the time taken to access a page from the RAM (at which point, the CPU is most likely idling) part of the CPU time? I'm not talking about fetching the page from the disk here, just fetching it from the RAM. Thanks

  • At what point in the render process of a web page can we interact with that page

    - by Bamerza
    I'd like to measure to distinct user experience points during the rendering of an HTML page: 1) Point which user sees the first painting of the page 2) Point at which user can interact with the page - meaning sees 75% of it or can actually register a button click or link click I am pretty certain these UX interactions can start before the HTML code is fully rendered, so would that instance be the JS func "OnLoad" or some other distinct measureable value/function? If it helps, we can even narrow the answer down to webkit based browsers.

  • Message reason why Execute method failed

    - by waanders
    I use the DAO method Execute to delete some records. If this fails this is clear by checking RecordsAffected (it will be 0). But is it possible to get the error message (for instance, to log or to show to the user)? I've try to delete the records by hand in the Table grid I get a clear dialog message, e.g. "The record cannot be deleted or changed because tabel x includes related records".

    When I try to compile with sbt some code containing an instance of a Table from this library I get this error: java.lang.AssertionError: assertion failed: unsatisfiable cyclic dependency in 'class Toolkit' It seems to work with Java so I don't understand why it fails in Scala. Here is the toolkit class: http://code.google.com/p/table-layout/source/browse/branches/v1/tablelayout/src/com/esotericsoftware/tablelayout/Toolkit.java As long as I get this error I'm totally stopped in my project :(.

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

  • Possible reasons and resolutions for time out

    - by ming yeow
    I cannot SSH into my instance - Operation timed out. What could be the reasons why, and what can I do to resolve it? Rebooting normally takes a long time to take effect, and might just makes things worst UPDATE: It is not about permissions - i can log in normally just fine. I suspect it might be because of memory issues
