  • Value object or not for 3d points ?

    - by Stefano Borini
    I need to develop a geometry library in python, describing points, lines and planes in 3d space, and various geometry operations. Related to my previous question. The main issue in the design is if these entities should have identity or not. I was wondering if there's a similar library out there (developed in another language) to take inspiration from, what is the chosen design, and in particular the reason for one choice vs. the other.

  • Question about ITextUndoHistory returned from TryGetHistory

    - by nick.ueda
    Everytime the IWpfTextView's TextBuffer changes I am trying to get the history's redostack and undostack and simply checking the count. When doing this I am encountering a "Method not supported exception" when trying to access the two stacks. Am I retrieving the history incorrectly or does VS not want me seeing/editing the contents of the stacks? I can post the code if necessary... Thanks, Nick

  • How is "Make Object ID" implemented in the .NET debugger?

    - by Omer Raviv
    Hi, I would like know how this feature is implemented in VS - I understand it holds some sort of weak-reference to the object in the debugged-application's memory, but how exactly is it accomplished? I know simply tracking the address (as in native code) wouldn't work, because the GC might move the object about, invalidating the address. Thanks.

  • add more than 30 days with Calendar's add() method in Java

    - by Haes
    Hi, I'm not quite sure what field to use when adding more than 30 days to a Java Calendar object. Is there any difference in between Calendar.DAY_OF_MONTH and Calendar.DAY_OF_YEAR? Example: GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_YEAR, 90); vs GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_MONTH, 90); Thanks.

  • May we have Ruby and Rails performance statistics? We're persuading the business to use Rails!

    - by thekingoftruth
    We're convincing our Products officer that we want to use JRuby on Rails, and we're having a hard time coming up with some statistics which show that: Coding time is less using Rails vs. say Struts or Zend Framework or what have you. Ruby (and JRuby in particular) performance isn't horrible (anymore). Rails performance isn't bad either. If you can get us some good stats quickly, we might have a chance!

  • Visual Studio Web Development - General Question?

    - by elviraHiggins
    Hi, I like using Visual Basic for C++. I'm a student I noticed the web development feature in it, and I was wondering if it is any good for web design, maybe if someone has used it or does use it if they can give a few words on weather or not it's worth learning? I have been using Dreamweaver as my platform for web design. So pretty much I'm asking Dreamweaver VS Visual Studio for webdesign, pros and cons?

  • Zend Framework - Can view helpers be user inside of partials?

    - by Bob Spryn
    Working on implementing view helpers and partials to create a group of reusable display objects. Previously addressed in my question here: http://stackoverflow.com/questions/2389531/zend-framework-when-to-use-viewscripts-partials-vs-view-helpers Wondering if partials can call view helpers of their own, and if they can whether those helpers will have access to the original view (since the partials don't).

  • Learn C# now or finish up with Java and then learn C#?

    - by Sahat
    Ok here is my situation. I've studied Java in my college for 2 semesters. But you know they teach you jack in there, just the basics. We skipped half of our textbook and even then our professors don't teach from section to section of each chapter. I don't blame them. It's hard as it is for new students to understand even the basic concepts of programming. Now this is a community college we are talking about and not Stanford, MIT or Berkeley. So like I said I've done 2 semester of Java. I really like our textbook because it has some challenging projects to do at the end of each chapter. This textbook is pretty clear and i have no problem understanding it (although 2-D and 3-D Arrays have given me some trouble). I have tried reading a few C# books such as Pro C# 2008 and .NET 3.5 and C# 4.0 in a Nutshell. I found these books to be dry and overloaded with information that put me to sleep (No offense to the authors of those 2 wonderful, according to amazon ratings, books). Would you suggest I finish my Java textbook, brush up my knowledge of Arrays, Polymorphism, and etc that are universal to most programming languages. And then switch to C#, plus the syntax is very similar so it should be easy to switch. Or should I just start learning C# right now from the very beginning? If it's the latter then could you recommend some free online resources that will keep me engaged and at the same time teach me everything I need to know about C#. Someone has recommended me to learn .NET first, but I found it to be not the brightest idea. .NET is just a big monster full of libraries. How am I going to apply it if I don't even know the C# or VB!? Anyway back to my question: Master Java and switch to C# or just go with C#? DISCLAIMER: I don't want to start .NET vs J2EE or C# vs Java flame war. I am going with C#. I've decided that I want to work in a Microsoft shop in the future. .NET is what I want to learn. Thanks! Will be waiting for the answers.

    When I make a setup project in VS 2008, and select <Setup Project>, Properties, PreRequisites then i can select SqlExpress2005 to be automatically included. What I am looking for is a walkthrough of how to get SqlExpress2008 included in the same manner. Second choice would be how to get (or make) a MergeModule (MSM) file to do the same.
