  • Programming Entity Framework, 2nd Edition (EF4) Table of Contents

    We are closing in on finalizing the 2nd edition of Programming Entity Framework! Although the rough draft chapters are already available through Safari’s Rough Cuts program (here: http://oreilly.com/catalog/9780596807252) I have been editing and reshaping the content since those chapters were published. You can get the final print edition (August 15th or perhaps a bit earlier) at O’Reilly or pre-order it here on Amazon.com (here) (and elsewhere of course!) I believe that the book will...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How to have table span the entire height?

    - by Yogendra
    Hi All, I have a html table and I am trying to have it span the entire page height. For some reason I am not able to get this to work. I have set the html, body and table height to be 100%, but the table still does not occupy the entire 100%. Heres the code. It is very basic because I am just trying to have the table occupy the entire height. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %> <style type="text/css"> body,html { margin:0; padding:0; height:100%; } </style> <table border="2" cellpadding="0" cellspacing="0" style="height:100%; width:100%" > <tr> <td>ABCD</td> </tr> </table> </form> I tried for couple of hours and I could not get it to work. Any help is really appreciated.

  • JUnit for Functions with Void Return Values

    - by RobotNerd
    I've been working on a Java application where I have to use JUnit for testing. I am learning it as I go. So far I find it to be useful, especially when used in conjunction with the Eclipse JUnit plugin. After playing around a bit, I developed a consistent method for building my unit tests for functions with no return values. I wanted to share it here and ask others to comment. Do you have any suggested improvements or alternative ways to accomplish the same goal? Common Return Values First, there's an enumeration which is used to store values representing test outcomes. public enum UnitTestReturnValues { noException, unexpectedException // etc... } Generalized Test Let's say a unit test is being written for: public class SomeClass { public void targetFunction (int x, int y) { // ... } } The JUnit test class would be created: import junit.framework.TestCase; public class TestSomeClass extends TestCase { // ... } Within this class, I create a function which is used for every call to the target function being tested. It catches all exceptions and returns a message based on the outcome. For example: public class TestSomeClass extends TestCase { private UnitTestReturnValues callTargetFunction (int x, int y) { UnitTestReturnValues outcome = UnitTestReturnValues.noException; SomeClass testObj = new SomeClass (); try { testObj.targetFunction (x, y); } catch (Exception e) { UnitTestReturnValues.unexpectedException; } return outcome; } } JUnit Tests Functions called by JUnit begin with a lowercase "test" in the function name, and they fail at the first failed assertion. To run multiple tests on the targetFunction above, it would be written as: public class TestSomeClass extends TestCase { public void testTargetFunctionNegatives () { assertEquals ( callTargetFunction (-1, -1), UnitTestReturnValues.noException); } public void testTargetFunctionZeros () { assertEquals ( callTargetFunction (0, 0), UnitTestReturnValues.noException); } // and so on... } Please let me know if you have any suggestions or improvements. Keep in mind that I am in the process of learning how to use JUnit, so I'm sure there are existing tools available that might make this process easier. Thanks!

  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • lisp, differences in assignment functions

    - by johnc
    I'm pretty new to lisp, so apologies for what may be a simple question, Whilst I understand the difference between DEFVAR and DEFPARAMETER (defvar only sets undefined variables), and the LET is for local scope only, what is the is the use of SETF as opposed to the other, previously mentioned assignment functions?

  • what will EcmaScript 6 bring to the table for us

    - by user697296
    Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

  • Lambda functions

    - by Oden
    Hey, I'm really interested in the way of using lambda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function (like this) or is there more behind?

  • Synchronizing Mysql Table Schema [on hold]

    - by user1122069
    I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

  • Display two images side by side on an HTML Page

    - by user77735
    I am trying to place two images of the same size side-by-side. If I use a "table" then I am able to display both images side-by-side. But in my CSS Stylesheet I am using a custom format for the table and this shows on the page containing the images too. But I want to just display both images without any custom background or border etc. I tried using "div", "span", "ul" & "li" etc. but failed in each case. How can I place two images (of same size) in a single line, without using a "table"? If I have to use "table" for the same, then how can I use two (or more) different formatting for my tables using CSS? Thank you. Lalit Kumar Barik

  • How to pass objects to functions in C++?

    - by Rakesh K
    I am new to C++ programming, but I have experience in Java. I need guidance on how to pass objects to functions in C++. Do I need to pass pointers, references, or non-pointer and non-reference values? I remember in Java there are no such issues since we pass just the variable that holds reference to the objects. It would be great if you could also explain where to use each of those options.

    I am using pdf2swf (http://www.swftools.org/) to convert PDF's to .swf. I have written a flex application that loads the swf generated by pdf2swf. I want to enable select , copy and paste functions on the loaded swf. Is there a way to do this. Please note I am able to extract the text from the loaded swf using textSnapshot, which means the pdf2swf does not convert the text to shapes.

    hi, I'm having a problem with a simple program I wrote, I want to perform a certain function according to the users input. I've already used a dictionary as a replacement for a switch to do assignment but when I try to assign functions to the dictionary it doesn't execute them... The code: def PrintValuesArea(): ## do this def PrintValuesLength(): ## do that def PrintValuesTime(): ## do third PrintTables={"a":PrintValuesArea,"l":PrintValuesLength,"t":PrintValuesTime} PrintTables.get(ans.lower()) ## ans is the user input what did I do wrong? It looks the same as all the examples I've seen....

  • Adding procedural C openGL functions to an iPhone project

    - by user309595
    I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?
