  • Dotnetnuke menu custom root

    - by Yobi21
    Is there anyway to use the built-in DNN Menu module to display a menu based at a different root node other than the current tab node? Given the following structure: Page1 -child1_1 -child1_2 Page3 Page2(hidden) -child2_1 -child2_2 In this scenario I will be having 2 menus on this skin. One will be normal navigation based off of the current node and the other will be a set of 'static' links to pages located outside the current node. When on Page1 the normal navigation will show Page1, Page3 and the children of Page1 nested under Page1. The 'static' links will use 'Page2' as their root and will show child2_1 and child2_2.

  • CSS - How can I center a div within a div?

    - by Spines
    I have an outer div that is 800px wide. I have an inner div that could be anywhere from 200 to 600px wide. I know how to center the inner div within the outer one if I set the inner one to have a specific width, but how do I center it since its a variable width? Is there a way to set the div to only be the width of the elements inside of it, rather than having it expand to fill its containing div?

  • hibernate many to many only save the new object and between table

    - by Joe
    I have the following tables: Student Student_Course Course Now when I create a student I only want to create a user and add a row to student_course. The "problem" I have is that when I set the set of courses in Student to cascade="save-update" that an update is also invoked on course. I was wondering if there was a way to prevent this.

  • Regex vs. string:find() for simple word boundary

    - by user576267
    Say I only need to find out whether a line read from a file contains a word from a finite set of words. One way of doing this is to use a regex like this: .*\y(good|better|best)\y.* Another way of accomplishing this is using a pseudo code like this: if ( (readLine.find("good") != string::npos) || (readLine.find("better") != string::npos) || (readLine.find("best") != string::npos) ) { // line contains a word from a finite set of words. } Which way will have better performance? (i.e. speed and CPU utilization)

  • Business Units vs Teams in CRM 2011

    - by GuruJ
    I've been told a few times that Business Units in CRM 2011 are "tricky" and shouldn't be set up lightly since they have irreversible consequences for a CRM 2011 implementation. On the other hand, teams in CRM 2011 seem much more flexible in managing record security. For what reason would I still choose to set up Business Units in CRM 2011? What can I do with Business Units that I can't with Teams (and vice versa)?

  • Creating a file/folder structure and zipping it up?

    - by makeee
    I have a directory of image files and I need a php script or shell script that will rename them, create a structure of nested directories, and then insert each image into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it. And then finally, I need the script to zip up the whole thing. There's probably not an existing php class that will do all this for me, but if anyone knows of a php class or other script available online that would handle a lot of this logic that would be great.

  • Getting data from the next row in Oracle cursor

    - by Chaotic_one
    Hi, I'm building nested tree and I need to get data for the next row in cursor, using Oracle. And I still need current row, so looping forward is not a solution. Example: OPEN emp_cv FOR sql_stmt; LOOP FETCH emp_cv INTO v_rcod,v_rname,v_level; EXIT WHEN emp_cv%NOTFOUND; /*here lies the code for getting v_next_level*/ if v_next_level > v_level then /*code here*/ elsif v_next_level < v_level then /*code here*/ else /*code here*/ end if; END LOOP; CLOSE emp_cv;

  • Changing the block size of a dfs file in Hadoop

    - by Sam
    I found that my map tasks is currently inefficient when parsing one particular set of files (total 2 TB). I'd like to change the block size of files in the Hadoop dfs (from 64MB to 128 MB). I can't find how to do it in the documentation for only one set of files and not the entire cluster, does anyone know the command that would change the block size when I upload it (ie copy from local to the dfs)? Thanks!

  • Hibernate (JPA) Entity with Static collection as a member

    - by Kyle Partridge
    Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database? I know I could just query this, but I was wondering if there was a more elegant solution, as it seems like something that other people may have come across.

  • How to modify complex argument strings in Perl

    - by mmccoo
    I have a cmdline that I'm trying to modify to remove some of the arguments. What makes this complex is that I can have nested arguments. Say that I have this: $cmdline = "-a -xyz -a- -b -xyz -b- -a -xyz -a-" I have three different -xyz flags that are to be interpreted in two different contexts. One is the -a context and the other is the -b context. I want to remove the "a" -xyz's but leave the ones in the "b" -xyz. How can I most effectively do this in Perl?

  • A 3-D grid of regularly spaced points

    - by Jack
    I want to create a list containing the 3-D coords of a grid of regularly spaced points, each as a 3-element tuple. I'm looking for advice on the most efficient way to do this. In C++ for instance, I simply loop over three nested loops, one for each coordinate. In Matlab, I would probably use the meshgrid function (which would do it in one command). I've read about meshgrid and mgrid in Python, and I've also read that using numpy's broadcasting rules is more efficient. It seems to me that using the zip function in combination with the numpy broadcast rules might be the most efficient way, but zip doesn't seem to be overloaded in numpy.

  • Optimal search queries

    - by Macros
    Following on from my last question http://stackoverflow.com/questions/2788082/sql-server-query-performance, and discovering that my method of allowing optional parameters in a search query is sub optimal, does anyone have guidelines on how to approach this? For example, say I have an application table, a customer table and a contact details table, and I want to create an SP which allows searching on some, none or all of surname, homephone, mobile and app ID, I may use something like the following: select * from application a inner join customer c on a.customerid = a.id left join contact hp on (c.id = hp.customerid and hp.contacttype = 'homephone') left join contact mob on (c.id = mob.customerid and mob.contacttype = 'mobile') where (a.ID = @ID or @ID is null) and (c.Surname = @Surname or @Surname is null) and (HP.phonenumber = @Homphone or @Homephone is null) and (MOB.phonenumber = @Mobile or @Mobile is null) The schema used above isn't real, and I wouldn't be using select * in a real world scenario, it is the construction of the where clause I am interested in. Is there a better approach, either dynamic sql or an alternative which can achieve the same result, without the need for many nested conditionals. Some SPs may have 10 - 15 criteria used in this way

  • Use reflection to get the value of a property by name in a class instance

    - by TheMoot
    Lets say I have class Person { public Person(int age, string name) { Age = age; Name = name; } public int Age{get;set} public string Name{get;set} } and I would like to create a method that accepts a string that contains either "age" or "name" and returns an object with the value of that property. Like the following pseudo code: public object GetVal(string propName) { return <propName>.value; } How can I do this using reflection? I am coding using asp.net 3.5, c# 3.5

  • "Inlining" (kind of) functions at runtime in C

    - by fortran
    Hi, I was thinking about a typical problem that is very JIT-able, but hard to approach with raw C. The scenario is setting up a series of function pointers that are going to be "composed" (as in maths function composition) once at runtime and then called lots and lots of times. Doing it the obvious way involves many virtual calls, that are expensive, and if there are enough nested functions to fill the CPU branch prediction table completely, then the performance with drop considerably. In a language like Lisp, I could probably process the code and substitute the "virtual" call by the actual contents of the functions and then call compile to have an optimized version, but that seems very hacky and error prone to do in C, and using C is a requirement for this problem ;-) So, do you know if there's a standard, portable and safe way to achieve this in C? Cheers

  • Increase the length of Xcode's "recent project" list?

    - by Bogatyr
    I switch in Xcode between working on a lot of different projects frequently (some I'm actively working on, some are old projects where I'm looking up code I want to re-use or quote in SO answers :)), so that part of my "working set" of projects invariably ends up falling off the recent project list. I do use finder tabs for the full working set of current project folders, but I really like the fast switching available using the recent projects list. Is there a way to increase the length of this list so that I can see more recently opened projects?

  • What is the most efficient approach to fetch category tree, products, brands, counts by subcategory

    - by alex227
    Symfony 1.4 + Doctrine 1.2. What is the best way to minimize the number of queries to retrieve products, subcategories of current category, product counts by subcategory and brand for the result set of the query below? Categories are a nested set. Here is my query: $q = Doctrine_Query::create() ->select('c.*, p.product,p.price, b.brand') ->from('Category c') ->leftJoin('c.Product p') ->leftJoin('p.Brand b') ->where ('c.root_id = ?', $this->category->getRootId()) ->andWhere('c.lft >= ?', $this->category->getLft()) ->andWhere('c.rgt <= ?', $this->category->getRgt()) ->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $treeObject = Doctrine::getTable('Category')->getTree(); $treeObject->setBaseQuery($q); $this->treeObject = $treeObject; $treeObject->resetBaseQuery(); $this->products = $q->execute();

  • Change background color of JQuery slider

    I understand I can set the background color of the value from min to the current slider selection by doing a: #slider .ui-slider-range { background: #88ac0b; } How do I set the background color for the entire slider (not just from the min or max to the selected value)

  • list within a list

    - by atm atm
    I'm working on this problem, but I cannot figure out the second part. I tried using reverse list but it did not work out how I planned it. Given a list L (e.g. [1,2,3,4]), write a program that generates the following nested lists: L1 = [[1],[1,2],[1,2,3],[1,2,3,4]], L2 = [[4],[3,4],[2,3,4],[1,2,3,4]]. My code that I have so far: mylist=[,1,2,3,4] print("Orginal list L=",mylist) n=len(mylist) l1=[] l2=[] for x in range(1,n+1,1): l1.append(mylist[0:x]) print("L1=",l1) #prints final product of l1 mylist.reverse() #this is where i get messed up for x in range(1,n+1,1): l2.append(mylist[0:x]) print("L2=",l2)
