• Is there a script that can dynamically list the contents of a folder?

  - by user294756

  I am redesigning my company's intranet site in Wordpress and one of the things they need is an archive of company memos. There are over 300 memos saved in one location and I'm wondering if there is a jQuery script that I can run that will read the contents of a local (network) folder and auto-generate a list of the contents of that folder dynamically (and generate those names as a hyperlink to that file, but if I can list the files, I can get include the hyperlink tag myself). I can always manually create the list of hyperlinks (would take a couple days to do so) but if I can generate it dynamically, whenever a new memo is added, the script will automatically include it making the site much easier to maintain. Is this at all possible? I know that this can probably be done in PHP, but the page I need to do this on is not a php page, it is one of the subpages that is created in wordpress that does not have a php file extension and can't run php code (that I know of) Thanks in advance for any and all assistance.

• Query for multiple joins

  - by Shailaja

  i have 3 tables named dataset,dataelem and transformdataelem with column names as below: main.Dataset ------------ datasetID (PK) applicationID main.Dataelem ------------- dataelemID(PK) datasetID(FK) dataelemname biztermID main.Transformdataelem ---------------------- OutputdataelemID InputdataelemID My requirement is: All tables are referenced. Extract all the dataelemId rows from dataelem table where applicationID of dataset table is equal to 1044 and biztermid shud be null. Then whatever resultant dataelemIDs from the above query should be matched with outputdataelemID of Transformdataelem table and we shud get the respective input dataelemId's. Again with these matched inputdataelemID's we shud get the dataelemname's from datelem table.

• Is it possible to access the line of code where a method is called from within that method?

  - by Dan Tao

  Disclaimers: I am not interested in doing this in any real production code. I make no claim that there's a good reason why I'm interested in doing this. I realize that if this is in any way possible, it must involve doing some highly inadvisable things. That said... is this possible? I'm really just curious to know. In other words, if I have something like this: int i = GetSomeInteger(); Is there any way from within GetSomeInteger that the code could be "aware of" the fact that it's being called in an assignment to the variable i? Again: no interest in doing this in any sort of real scenario. Just curious!

• Flex: Load images and swf's dynamically

  - by Lizzan

  I'm building a slide-show like application in Flex and I'm trying to load images dynamically. The images are in a folder outside the application folder. This is the folder structure: /Bildvisare-debug/ Bildvisare.html Bildvisare.swf /Images/ 01_02_01_01_B.jpg 01_02_01_01_T.JPG I'm reading the image names from an XML file and get them with a path of ../Images/01_03_01_01_B.jpg. In my mxml-file I've got an SWFLoader named picture and I try to load the images with the following code: this.picture.source = images[currentImg]; //E.g. ../Images/01_03_01_01_B.jpg this.picture.load(); The problem is that the images never show up, I only get the icon for a missing image. Can anyone help?

• Reference to an instance method of a particular object

  - by Andrey

  In the following code, if i try to pass method reference using the class name, works. But passing the reference variable compiler gives an error, i do not understand why? public class User { private String name; public User(String name) { this.name = name; } public void printName() { System.out.println(name); } } public class Main { public static void main(String[] args) { User u1 = new User("AAA"); User u2 = new User("BBB"); User u3 = new User("ZZZ"); List<User> userList = Arrays.asList(u1, u2, u3); userList.forEach(User::printName); // works userList.forEach(u1::printName); // compile error } } Thanks,

• How do you extend a Ruby module with macro-like metaprogramming methods?

  - by Ian Terrell

  Consider the following extension (the pattern popularized by several Rails plugins over the years): module Extension def self.included(recipient) recipient.extend ClassMethods recipient.class_eval { include InstanceMethods } end module ClassMethods def macro_method puts "Called macro_method within #{self.name}" end end module InstanceMethods def instance_method puts "Called instance_method within #{self.object_id}" end end end If you wished to expose this to every class, you can do the following: Object.send :include, Extension Now you can define any class and use the macro method: class FooClass macro_method end #=> Called macro_method within FooClass And instances can use the instance methods: FooClass.new.instance_method #=> Called instance_method within 2148182320 But even though Module.is_a?(Object), you cannot use the macro method in a module: module FooModule macro_method end #=> undefined local variable or method `macro_method' for FooModule:Module (NameError) This is true even if you explicitly include the original Extension into Module with Module.send(:include, Extension). How do you add macro like methods to Ruby modules?

• Shuffle array variables in a pre-specified order, without using extra memory of "size of input array"

  - by Eternal Learner

  Input : A[4] = {0,4,-1,1000} - Actual Array P[4] = {1,0,3,2} - Order to be reshuffled Output: A[4] = {4,0,1000,-1} Condition : Don't use an additional array as memory. Can use an extra variable or two. Problem : I have the below program in C++, but this fails for certain inputs of array P. #include<iostream> using namespace std; void swap(int *a_r,int *r) { int temp = *r; *r = *a_r; *a_r = temp; } int main() { int A[4] = {0,4,-1,1000}; int P[4] = {3,0,1,2}; int value = A[0] , dest = P[0]; for(int i=0; i<4;i++) { swap(&A[dest],&value); dest = P[dest]; } for(int i=0;i<4;i++) cout<<A[i]<<" "; }

• How to do insert one row from one table to another table(what has less columns)?

  - by chobo2

  Hi I am trying to find rows that are not in one table and insert them into another. The table I am trying to insert into has less columns then the other one. These columns are null but it would be cool if I could hardcode a value before I do the insert. But I am having so much trouble with just trying to get it to insert. I have something like this SELECT p.ProductId, p.ProductName INTO SomeTable FROM Product as p WHERE p.ProductName != 'iPad' I will get a error like this though Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "p.ProductId" could not be bound. I am not sure what I am doing wrong. I copied and pasted the names in so I don't think it is a spelling mistake. I am using ms sql 2005 express.

• Function argument treated as undeclared

  - by Mikulas Dite

  I've prepared this simple example which is not working for me #include <stdio.h> #include <stdlib.h> FILE *fp; char filename[] = "damy.txt"; void echo (char[] text) { fp = fopen(filename, "a"); fwrite(text, 1, strlen(text), fp); fclose(fp); printf(text); } int main () { echo("foo bar"); return 0; } It's supposed to write both to command window and to file. However, this gives compilation error - the text used in echo() is not declared. Does c need another declaration of the variable?

• the use of private keyword

  - by LAT

  Hi everyone I am new to programming. I am learning Java now, there is something I am not really sure, that the use of private. Why programmer set the variable as private then write , getter and setter to access it. Why not put everything in public since we use it anyway. public class BadOO { public int size; public int weight; ... } public class ExploitBadOO { public static void main (String [] args) { BadOO b = new BadOO(); b.size = -5; // Legal but bad!! } } I found some code like this, and i saw the comment legal but bad. I don't understand why, please explain me.

• C - memset segfault for statically allocated char array

  - by user1327031

  I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

• How do XAML files associate with cs files?

  - by LLS

  It seems that XAML files should have corresponding .cs files in a C# project. I know Visual Studio does all the things for us. I'm just curious how they are linked together? I mean, are they specified in the project file, or just because they have the same names? And also, App.xaml file specifies the startup file, but how does the compiler know? Is it possible to appoint another file other than App.xaml to do the same things as App.xaml does?

• Scalling connected lines

  - by Hristo

  Hello, I have some kind of a shape consisting of vertical, horizontal and diagonal lines. I have starting X,Y and ending X,Y (this is my input - just 2 points defining a line) of each line and I would like to make the whole shape scalable (just by changing the value of a scale ratio variable), so that I can still preserve the proper connection of the lines and the proportions as well. Just for getting a better idea of what I mean: it'd be as if I had the same lines in a vector editor. Would that be possible with an algorithm, and could you please, give me another possible solution if there is no such algorithm ? Thank you very much in advance!

• Dynamic SQL queries in code possible?

  - by SeanD

  Instead of hard coding sql queries like Select * from users where user_id =220202 can these be made dynamic like Select * from $users where $user_id = $input. Reason i ask is when changes are needed to table/column names i can just update it in one place and don't have to ask developers to go line by line to find all references to update. It is very time consuming. And I do not like the idea of exposing database stuff in the code. My major concern is load time. Like with dynamic pages, the database has to fetch the page content, same way if queries are dynamic first system has to lookup the references then execute the queries, so does it impact load times? I am using codeignitor PHP. If it it possible then the next question is where to store all the references? In the app, in a file, in the DB, and how?

• How to program a Sort feature

  - by Brian Roisentul

  I'm working on Ruby on rails 2.3.4 and I'm trying to develop a Sort feature on my website's search page(its url is /anuncios/buscar). What I tried is to create a "map" on routes file: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' Then, I wrote this on the view: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance(@announcements) %> And finally, I created a method in the controller, as is specified on the routes' line: def search_filer_relevance raise params.inspect end First of all, as I'm sorting search results, I'd like to keep them in their public variable called @announcements. Please help me do this. An the other thing is that when I click the link I get an error due its trying to access the Show action instead of search_filter_relevance as specified in routes. Why is this happening?

• What are parts of a PHP function named?

  - by MikeG

  I am having trouble figuring out a problem and it is because I don't know the correct terms to be searching for. Could someone please name all the parts of a PHP function and if I'm missing something please add it. function my_function( non_variable $variable_one, $variable_two = "", $variable_three ) { /* inside stuff (Statement?) */ } The answer I'm looking for would look something like this function: declaration my_function: name non_variable: Please Answer $variable_one: variable filled with non_variable The one I really need to know about are non_variable and $variable_one, Thanks!

• C# - Printing out groupnames, items and subitems in a loop?

  - by Nike

  What I'm trying to do, is to store all groupnames, items and subitems from a listview into a string. Take a look at the following screenshot. I'm kind of stuck though, with the loop. I'm pretty sure i can figure out how to actually store it in a variable though. The following code will loop through all of the listview Items: int countGroups = csslistview.Items.Count; foreach (ListViewItem lvi in csslistview.Items){ //code here countGroups++; } But i can't figure out how to loop through all of the Groups. I tried this, but it's not working: int countGroups = csslistview.Groups.Count; foreach (ListViewItem lvi in csslistview.Items){ //code here countGroups++; } I'm trying to echo it out as CSS, if you're wondering. The grouname is the id/class/tag, the item is the rule, and the subitem is the property. So, any ideas?

• Extending appengine's db.Property with caching

  - by Noio

  I'm looking to implement a property class for appengine, very similar to the existing db.ReferenceProperty. I am implementing my own version because I want some other default return values. My question is, how do I make the property remember its returned value, so that the datastore query is only performed the first time the property is fetched? What I had is below, and it does not work. I read that the Property classes do not belong to the instances, but to the model definition, so I guess that the return value is not cached for each instance, but overwritten on the model every time. Where should I store this _resolved variable? class PageProperty(db.Property): data_type = Page def get_value_for_datastore(self, model_instance): page = super(PageProperty, self).get_value_for_datastore(model_instance) self._resolved = page return page.key().name() def make_value_from_datastore(self, value): if not hasattr(self, '_resolved'): self._resolved = Page.get_by_name(value) return self._resolved

• Using Classes / OOP in PHP

  - by Alex Demchak

  I'm pretty proficient with PHP, outside of OOP - which I am just now starting to jump in to. I've been watching videos and reading tutorials, but they are all still pretty confusing... If I have FILE 1 (class.time.php) class Time { function GetTime(){ $time = date('H:i:s'); printf($time); } } and then in a nother php page I've got FILE 2 (page.php) I can do include('class.time.php'); and then anywhere in this page I can then do $time = new Time; //Calling the class and setting the class to a variable $time->GetTime(); //This is BASICALLY saying (run the 'GetTime' function in the 'Time Class' My main question is, is the comment above (This is BASICALLY saying.....) correct? or is there a better way to think of it?

• bash tools for parsing arguments

  - by BCS

  I have a bash script that uses a few variables (call them $foo and $bar). Right now the script defines them at the top with hard coded values like this: foo=fooDefault bar=barDefault .... # use $foo and $bar What I want is to be able to use the script like any of these: myscript # use all defaults myscript -foo=altFoo # use default bar myscript -bar=altBar # use default foo myscript -bar=altBar -foo=altFoo An ideal solution would allow me to just list the variable that I want to check for flags for. Is there a reasonably nice way to do this? I've seen getopt and I think it might do about 70% of what I'm looking for but I'm wondering if there is a tool or indium that builds on it or the like that gets the rest.
