  • Decrement all int values in Dictionary

    - by Jon
    I have a Dictionary<string,int> and I simply want to decrement the value in my dictionary by one. I have this but not sure if its best practice. foreach (KeyValuePair<string, int> i in EPCs) { EPCs[i.Key] = i.Value - 1; }

  • What scripts should not be ported from bash to python?

    - by Jack
    I decided to rewrite all our Bash scripts in Python (there are not so many of them) as my first Python project. The reason for it is that although being quite fluent in Bash I feel it's somewhat archaic language and since our system is in the first stages of its developments I think switching to Python now will be the right thing to do. Are there scripts that should always be written in Bash? For example, we have an init.d daemon script - is it OK to use Python for it? We run CentOS. Thanks.

  • is this possible: c# collection of Type with constrains, or collection of generic type?

    - by Jon
    I'm trying to store types in a collection, so that i can later instantiate objects of the types in the collection. But I'm not sure how to do this the best way. What i have so far: List<Type> list = new List<Type>(); list.Add(typeof(MyClass)); var obj = (MyClass)Activator.CreateInstance(list[0]); I would like to have some constrains on the Type, or better yet, just a generic type in the collection instead of an instantiated Type object. Is this possible?

  • How do virtual destructors work?

    - by Jack
    I am using gcc. I am aware how the virtual destructors solve the problem when we destroy a derived class object pointed by a base class pointer. I want to know how do they work? class A { public: A(){cout<<"A constructor"<<endl;} ~A(){cout<<"A destructor"<<endl;} }; class B:public A { public: B(){cout<<"B constructor"<<endl;} ~B(){cout<<"B destructor"<<endl;} }; int main() { A * a = new B(); delete a; getch(); return 0; } When I change A's destructor to a virtual function, the problem is solved. What is the inner working for this. Why do I make A's destructor virtual.

  • Where are global variables stored in memory?

    - by Jack
    Are they stored in the heap or there is separate area where they are stored? Similarly where are static variables stored in memory. They can't be stored in frames as they will get destroyed when the function returns. PS - Can someone suggest a good book that talks about memory mapping for C/C++.

  • how to dynamically (re)position an element according to the bottom of the page using JS / Jquery?

    - by jon
    Hi All, the back story: i have a tab section on a page which when navigated through displays sections (divs) of varying height. the result, is that certain inputs (which are strangely positioned for reasons i can't change) on this page reposition themselves problematically. the proposed solution: as the page height changes, have these problem inputs repositioned according to the page bottom (from which their appropriate distances are always a constant). what i'm thinking is that i need some js that does something like, page height change triggers input position from bottom to = x. there are two inputs if that's at all relevant. :) if only there was css for this (i know there is under normal circumstances, but trust me -- not in this case). thanks for your time & help i've been struggling with this for weeks!

  • How do I get Nunit to run selenium tests against different servers?

    - by Jon
    I have an Nunit test which uses selenium RC to run tests against our UI. I want to run the tests against 2 different servers, which means having the call to selenium.open() with 2 different servers. However, I don't want to have 2 different Nunit test suites that do the same thing but against different servers. I need a way of passing parameters from Nant or the Nunit driver program to specific which server to test against. Is there anyway to do this?

  • What is the best way to include a php file as a template?

    - by Jon
    I have simple template that's html mostly and then pulls some stuff out of SQL via PHP and I want to include this template in three different spots of another php file. What is the best way to do this? Can I include it and then print the contents? Example of template: Price: <?php echo $price ?> and, for example, I have another php file that will show the template file only if the date is more than two days after a date in SQL.

  • JQuery .each() backwards

    - by Jack Mills
    Hi, I'm using JQuery to select some elements on a page and then move them around in the DOM. The problem I'm having is I need to select all the elements in the reverse order that JQuery naturally wants to select them. For example: <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> <li>Item 4</li> <li>Item 5</li> </ul> I want to select all the li items and use the .each() command on them but I want to start with Item 5, then Item 4 etc. Is this possible? Thanks

  • 2 basic but interesting questions about .NET

    - by b-gen-jack-o-neill
    Hi, when I first saw C#, I thought this must be some joke. I was starting with programming in C. But in C# you could just drag and drop objects, and just write event code to them. It was so simple. Now, I still like C the most, becouse I am very attracted to the basic low level operations, and C is just next level of assembler, with few basic routines, so I like it very much. Even more becouse I write little apps for microcontrollers. But yeasterday I wrote very simple control program for my microcontroller based LED cube in asm, and I needed some way to simply create animation sequences to the Cube. So, I remembered C#. I have practically NO C# skills, but still I created simple program to make animation sequences in about hour with GUI, just with help of google and help of the embeded function descriptions in C#. So, to get to the point, is there some other reason then top speed, to use any other language than C#? I mean, it is so effective. I know that Java is a bit of similiar, but I expect C# to be more Windows effective since its directly from Microsoft. The second question is, what is the advantage of compiling into CIL, and than run by CLR, than directly compile it into machine code? I know that portability is one, but since C# is mainly for Windows, wouldn´t it be more powerfull to just compile it directly? Thanks.

  • Update all but one result?

    - by Jack M.
    I'm trying to update a table to remove all but the first instance of a group. Basically, I have a table with vehicle data related to an insurance policy. Each policy should only have one power_unit. Everything else should be a towed unit. Unfortunately, a bug has been duplicating power units, and now I need to clean this up. There are ~10k records in the database, and ~4k of them have doubled up power units. The important bits of my table (call it test1 for now) are: +------------+---------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+---------+------+-----+---------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | policy_id | int(10) | NO | | NULL | | | power_unit | int(1) | NO | | 0 | | +------------+---------+------+-----+---------+----------------+ And some sample data: +----+-----------+------------+ | id | policy_id | power_unit | +----+-----------+------------+ | 1 | 1 | 1 | | 2 | 1 | 1 | | 3 | 1 | 1 | | 4 | 2 | 1 | | 5 | 2 | 1 | | 6 | 2 | 1 | | 7 | 4 | 1 | | 8 | 4 | 1 | | 9 | 4 | 1 | | 10 | 5 | 1 | | 11 | 5 | 1 | | 12 | 6 | 1 | +----+-----------+------------+ Basically I'd like to end up where policy_id 1 has only one power_unit=1. Same for policy_id 2, 3, 4, etc. For policy_id 6, nothing should change (there is only one entry, and it is a power_unit already). I don't know if this is possible, but it was an intriguing problem for me, so I thought you guys might find it the same.

  • How do i change everything behind a certain point in a Jagged array?

    - by Jack Null
    Say I have a jagged array, and position 2,3 is taken by int 3. Every other spot is filled with int 0. How would I fill all the positions behind 2,3 with a 4? 0 0 0 0 0 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 to this: 4 4 4 4 4 4 4 4 4 4 4 4 4 3 0 0 0 0 0 0 0 Ive tried variations of this: int a = 2; int b = 3; for (int x = 0; x < a; x++) { for (int y = 0; y < board.space[b].Length; y++) { board.space[x][y] = 4; } }

  • PHP: Need help with simple XML.

    - by Jack
    I am beginner in PHP. I am trying to parse this xml file. <relationship> <target> <following type="boolean">true</following> <followed_by type="boolean">true</followed_by> <screen_name>xxxx</screen_name> <id type="integer">xxxx</id> </target> </relationship> I need to get the value of the field 'following type="boolean" ' and here's my code - $xml = simplexml_load_string($response); foreach($xml->children() as $child) { if ($child->getName() == 'target') { foreach($child->children() as $child_1) if ( $child_1->getName() == 'following') { $is_my_friend = (bool)$child_1; break; } break; } } but I am not getting the correct output. I think the ' type="boolean" ' part of the field is creating problems. I know this might be a very trivial problem. Kindly bear with my ignorance. Please help.
