  • Should enumerations be placed in a separate file or within another class?

    - by Icono123
    I currently have a class file with the following enumeration: using System; namespace Helper { public enum ProcessType { Word = 0, Adobe = 1, } } Or should I include the enumeration in the class where it's being used? I noticed Microsoft creates a new class file for DockStyle: using System; using System.ComponentModel; using System.Drawing.Design; namespace System.Windows.Forms { public enum DockStyle { None = 0, Top = 1, Bottom = 2, Left = 3, Right = 4,. Fill = 5, } }

  • test="" on a boolean always returns true

    - by user70448
    Why does <xsl:if test="<XPATH to boolean value here>"> ... </xsl:if> ALWAYS return true? Since boolean can be 0,1,"false" and "true" by definition, the ONLY way to test for a boolean value is to do string comparison against these. This can't be right.

  • Counting point size based on chart area during zooming/unzoomin

    - by Gacek
    Hi folks. I heave a quite simple task. I know (I suppose) it should be easy, but from the reasons I cannot understand, I try to solve it since 2 days and I don't know where I'm making the mistake. So, the problem is as follows: - we have a chart with some points - The chart starts with some known area and points have known size - we would like to "emulate" the zooming effect. So when we zoom to some part of the chart, the size of points is getting proportionally bigger. In other words, the smaller part of the chart we select, the bigger the point should get. So, we have something like that. We know this two parameters: initialArea; // Initial area - area of the whole chart, counted as width*height initialSize; // initial size of the points Now lets assume we are handling some kind of OnZoom event. We selected some part of the chart and would like to count the current size of the points float CountSizeOnZoom() { float currentArea = CountArea(...); // the area is counted for us. float currentSize = initialSize * initialArea / currentArea; return currentSize; } And it works. But the rate of change is too fast. In other words, the points are getting really big too soon. So I would like the currentSize to be invertly proportional to currentArea, but with some scaling coefficient. So I created the second function: float CountSizeOnZoom() { float currentArea = CountArea(...); % the area is counted for us. // Lets assume we want the size of points to change ten times slower, than area of the chart changed. float currentSize = initialSize + 0.1f* initialSize * ((initialArea / currentArea) -1); return currentSize; } Lets do some calculations in mind. if currentArea is smaller than initialArea, initialArea/currentArea > 1 and then we add "something" small and postive to initialSize. Checked, it works. Lets check what happens if we would un-zoom. currentArea will be equal to initialArea, so we would have 0 at the right side (1-1), so new size should be equal to initialSize. Right? Yeah. So lets check it... and it doesn't work. My question is: where is the mistake? Or maybe you have any ideas how to count this scaled size depending on current area in some other way?

  • How to represent "{{" in a django template?

    - by rxin
    I'm trying to output in bibtex format in Django and the template looks like this: @{{ pubentry.type }{, author = {{% for author in pubentry.authors.all %}{{ author.first_name }} {{ author.middle_name }} {{ author.last_name }}{% if not forloop.last %} and {% endif %} {% endfor %}}, title = {{{ pubentry.title }}}, journal = {{{ pubentry.journal }}} } The problem is with the "{{{" or "{{%". One way to go around the problem is to add a space after the first "{", but that kind of tamper the format. What's the right way to escape { in Django templates?

  • encryption of a single character

    - by SystemicPlural
    What is the minimum number of bits needed to represent a single character of encrypted text. eg, if I wanted to encrypt the letter 'a', how many bits would I require. (assume there are many singly encrypted characters using the same key.) Am I right in thinking that it would be the size of the key. eg 256 bits?

  • What is the lightest way to make a huge chess-like grid?

    - by Sotkra
    Hey there I'm working on a browser-game and I can't help but wonder about what's the lightest way to make the grid/board on which the game takes place. Right now, as a mere sample, I'll show you this: http://sotkra.com/game/ Now, as the grid gets bigger and bigger, the table and its td's create a very heavy filepage which in turn...sucks in more resources from the browser engine and computer. So, is a table with td's the most lightweight way to craft a huge grid-like board or is there something lighter that you recommend? Cheers Sotkra

    - by Tommy Coffee
    Here's what I' trying to do: Currently I am using this to create an array of all elements matching the class name of '.cookie'. Right now I am getting the text value of that element, which is not what I need: var getAllCookies = $('.cookie').text(); var cookiesArray = jQuery.makeArray(getAllCookies); alert(cookiesArray[0]); What I need is to find all elements of a certain class (.cookie), get that elements ID value and store that ID value inside of array.

  • Commitment to Zend Framework - any arguments against?

    - by Pekka
    I am refurbishing a big CMS that I have been working on for quite a number of years now. The product itself is great, but some components, the Database and translation classes for example, need urgent replacing - partly self-made as far back as 2002, grown into a bit of a chaos over time, and might have trouble surviving a security audit. So, I've been looking closely at a number of frameworks (or, more exactly, component Libraries, as I do not intend to change the basic structure of the CMS) and ended up with liking Zend Framework the best. They offer a solid MVC model but don't force you into it, and they offer a lot of professional components that have obviously received a lot of attention (Did you know there are multiple plurals in Russian, and you can't translate them using a simple ($number == 0) or ($number > 1) switch? I didn't, but Zend_Translate can handle it. Just to illustrate the level of thorougness the library seems to have been built with.) I am now literally at the point of no return, starting to replace key components of the system by the Zend-made ones. I'm not really having second thoughts - and I am surely not looking to incite a flame war - but before going onward, I would like to step back for a moment and look whether there is anything speaking against tying a big system closely to Zend Framework. What I like about Zend: As far as I can see, very high quality code Extremely well documented, at least regarding introductions to how things work (Haven't had to use detailed API documentation yet) Backed by a company that has an interest in seeing the framework prosper Well received in the community, has a considerable user base Employs coding standards I like Comes with a full set of unit tests Feels to me like the right choice to make - or at least, one of the right choices - in terms of modern, professional PHP development. I have been thinking about encapsulating and abstracting ZF's functionality into own classes to be able to switch frameworks more easily, but have come to the conclusion that this would not be a good idea because: it would be an unnecessary level of abstraction it could cost performance the big advantage of using a framework - the existence of a developer base that is familiar with its components - would partly be cancelled out therefore, the commitment to ZF would be a deep one. Thus my question: Is there anything substantial speaking against committing to the Zend Framework? Do you have insider knowledge of plans of Zend Inc.'s to go evil in 2011, and make it a closed source library? Is Zend Inc. run by vampires? Are there conceptual flaws in the code base you start to notice when you've transitioned all your projects to it? Is the appearance of quality code an illusion? Does the code look good, but run terribly slow on anything below my quad-core workstation?

  • android - How to draw only the sprite from an image on the canvas

    - by user1320494
    this is the first time for me here, so I hope I'm doing this right :) My question is the following: how do I draw the sprite from an image on the canvas, so that I don't get the entire (squared) image to show, but only the parts of the image I want (= the sprite). For example, I have an image of a robot on a white background and I only want to see the robot, and not the white background. I hope someone here can help me with this problem, because it's giving me headaches of not knowing how to do it :P

  • WP7 PanoramaItem with Icon/Button next to Header

    - by Ramon Bosch
    Windows Phone 7's People hub has an "all" panorama item with "search" and a "new" buttons right next to the header/title. I can't seem to accomplish this with PanoramaItem in Visual Studio using the standard Panorama control. I don't know enough Silverlight/WPF either to be able to position something manually and control transitions/movement correctly. How can I set a button (or any object, for that matter) to go alongside the header of a wp7 PanoramaItem? Thanks!

  • Parsing line with delimiter in Python

    - by neversaint
    I have lines of data which I want to parse. The data looks like this: a score=216 expect=1.05e-06 a score=180 expect=0.0394 What I want to do is to have a subroutine that parse them and return 2 values (score and expect) for each line. However this function of mine doesn't seem to work: def scoreEvalFromMaf(mafLines): for word in mafLines[0]: if word.startswith("score="): theScore = word.split('=')[1] theEval = word.split('=')[2] return [theScore, theEval] raise Exception("encountered an alignment without a score") Please advice what's the right way to do it?
