  • Evaluating creation of GUI via file vs coding

    - by nevets1219
    I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.

  • Dynamic creation of a pointer function in c++

    - by Liberalkid
    I was working on my advanced calculus homework today and we're doing some iteration methods along the lines of newton's method to find solutions to things like x^2=2. It got me thinking that I could write a function that would take two function pointers, one to the function itself and one to the derivative and automate the process. This wouldn't be too challenging, then I started thinking could I have the user input a function and parse that input (yes I can do that). But can I then dynamically create a pointer to a one-variable function in c++. For instance if x^2+x, can I make a function double function(double x){ return x*x+x;} during run-time. Is this remotely feasible, or is it along the lines of self-modifying code?

  • How does KMS (Windows Server 2008 R2) differentiate clients?

    - by Joe Taylor
    I have recently installed a KMS Server in our domain and deployed 75 new Windows 7 machines using an image I made using Acronis True Image. There are 2 variations of this image rolled out currently. When I go to activate the machines it returns that the KMS count is not sufficient. On the server with a slmgr /dlv it shows: Key Management Service is enabled on this machine. Current count: 2 Listening on Port: 1688 DNS publishing enabled KMS Priority: Normal KMS cumulative requests received from clients: 366 Failed requests received: 2 Requests with License status unlicensed: 0 Requests with License status licensed: 0 Requests with License status Initial Grace period: 1 Requests with License statusLicense expired or hardware out of tolerance: 0 Requests with License status Non genuine grace period: 0 Requests with License status Notification: 363 Is it to do with the fact that I've used the same image for all the PC's? If so how do I get round this. Would changing the SID help? OK knowing I've been thick whats the best way to rectify the situation. Can I sysprep the machines to OOBE on each individual machine? Or would NewSID work?

  • benefit os having a factory for object creation?

    - by ajsie
    im trying to understand the factory design pattern. i dont understand why it's good to have a middleman between the client and the product (object that the client wants). example with no factory: $mac = new Mac(); example with a factory: $appleStore = new AppleStore(); $mac = $appleStore->getProduct('mac'); how does the factory pattern decouple the client from the product? could someone give an example of a future code change that will impact on example 1 negative, but positive in example 2 so i understand the importance of decoupling? thanks

  • Jquery - removing an image before the client browser attempts to download it

    - by ajbrun
    Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?

  • Meaning of NEXT in Linked List creation in perl

    - by seleniumnewbie
    So I am trying to learn Linked Lists using Perl. I am reading "Mastering Algorithms with Perl" by Job Orwant. In the book he explains how to create a linked list I understand most of it, but I just simply fail to understand the command/index/key NEXT in the second last line of the code snippet. $list=undef; $tail=\$list; foreach (1..5){ my $node = [undef, $_ * $_]; $$tail = $node; $tail = \${$node->[NEXT]}; # The NEXT on this line? } What is he trying to do there? Isn $node a scalar, which stores the address of the unnamed array. Also even if we are de-referencing $node, should we not refer to the individual elements by an index number example (0,1). If we do use "NEXT" as a key, is $node a reference to a hash? I am very confused. Something in plain English will be highly appreciated.

  • Best way to develop a level from Top down image using 3dmax

    - by fire'fly
    I have to create a game level from a top down view of an area. I used a plane converted to an editable poly to do the job. I used edges to create the top view of roads, walkways and parks so that i can extrude/edit them later. My problem is the curves in the road look blocky I tried appying mesh smooth modifier on the final model but that interfered with material mapping. Again i tried it on the plane without the extrusions and still the modifier does not work(The roads loose their shape). I know one way to solve the problem is to add more vertices on the curve and transform their location to create a more natural curve but i have a lot of curves so before doing it manually i need to know if there is a tool that refines the curves. Also i need to know if there is a better or proper way of doing the task.

  • Intercept creation of activities when the application is restored

    - by Johan Bilien
    Most of our activities access a user-specific model. All these activities inherit from a ModelActivity base class, which provides a getModel() call. When one of these activities detect that the user has signed out (through the AccountManager callback), it sticks to its existing model, but prepares to exit back to the root activity (which is not user-specific) by starting its intent with FLAG_ACTIVITY_CLEAR_TOP. If however the user deletes an account while the app is not running, we run into trouble when the activity is restored. Now the activity needs to handle there not being a model, which makes the code more complicated and bug-prone. Ideally we would intercept the application restore process before the activity is created. Then we would check whether we have an account and a model, and if not clear up the saved stack of activities, and restart from our root activity instead of the last saved activity. But as far as I can tell the first place where we can run code is in the onCreate callback of the activity. Is there a way to run some code when the application is restored from background-saving, but before the saved activity is created?

  • Create a Texture2D from larger image

    - by Dialock
    I am having trouble with the basic logic of this solution: Xna: Splitting one large texture into an array of smaller textures in respect to my specific problem (specifically, I'm looking at the second answer.) How can I use my source rectangle that I already use for drawing to create a new Texture2D? spriteBatch.Draw(CurrentMap.CollisionSet, currentMap.CellScreenRectangle(x, y), CurrentMap.TileSourceRectangle(currentMap.MapCells[x, y].TileDepths[4]), Color.FromNonPremultiplied(0,0,0, 45), 0.0f, Vector2.Zero, SpriteEffects.None, 0.91f); I know I want a method that I started so: //In Update Method of say the player's character. Texture2D CollisionTexture = ExtractTexture(MapManager.CurrentMap.CollisionSet, MapManager.TileWidth, MapManager.TileHeight); // In MapManager Class who knows everything about tiles that make up a level. public Texture2D ExtractTexture(Texture2D original, int partWidth, int partheight, MapTile mapCell) { var dataPerPart = partWidth * partheight; Color[] originalPixelData = new Color[original.Width * original.Height]; original.GetData<Color>(originalPixelData); Color[] newTextureData = new Color[dataPerPart]; original.GetData<Color>(0, CurrentMap.TileSourceRectangle(mapCell.TileDepths[4]), originalPixelData, 0, originalPixelData.Count()); Texture2D outTexture = new Texture2D(original.GraphicsDevice, partWidth, partheight); } I think the problem is I'm just not understanding the overload of Texture2D.GetData< Part of my concern is creating an array of the whole texture in the first place. Can I target the original texture and create an array of colors for copying based on what I already get from the method TileSourceRecatangle(int)?

  • Having trouble applying style to SVG using JavaScript upon object creation

    - by Jack Roscoe
    Hi, I have a function which creates an SVG text object using JavaScript. As soon as the object is created, I want it to have the style attribute which in CSS would be text-anchor: left. Currently, it doesn't work. I have tried many variations, and I also read that when using styles in JavaScript you must remove any '-' dashes and format the attribute name in camel casing (is this true?). Can anybody spot my mistake? Here's my code: RenderTextBox:function() { this.textBox = paper.text(this.x, this.y, this.htmlTextBox); this.textBox.style.textAnchor="left"; }
