  • Printing entire array in C#

    - by DMan
    I have a simple 2D array: int[,] m = {{0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} }; How can I print this out onto a text file or something? I want to print the entire array onto a file, not just the contents. For example, I don't want a bunch of zeroes all in a row: I want to see the {{0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} }; in it.

  • Advanced Array Sorting in Ruby

    - by Ruby Beginner
    I'm currently working on a project in ruby, and I hit a wall on how I should proceed. In the project I'm using Dir.glob to search a directory and all of its subdirectories for certain file types and placing them into an arrays. The type of files I'm working with all have the same file name and are differentiated by their extensions. For example, txt_files = Dir.glob("**/*.txt") doc_files = Dir.glob("**/*.doc") rtf_files = Dir.glob("**/*.rtf") Would return something similar to, FILECON.txt ASSORTED.txt FIRST.txt FILECON.doc ASSORTED.doc FIRST.doc FILECON.rtf ASSORTED.rtf FIRST.rtf So, the question I have is how I could break down these arrays efficiently (dealing with thousands of files) and placing all files with the same filename into an array. The new array would look like, FILECON.txt FILECON.doc FILECON.rtf ASSORTED.txt ASSORTED.doc ASSORTED.rtf etc. etc. I'm not even sure if glob would be the correct way to do this (all the files with the same file name are in the same folders). Any help would be greatly appreciated!

  • Custom array sort in perl

    - by ABach
    I have a perl array of to-do tasks that looks like this: @todos = ( "1 (A) Complete online final @evm4700 t:2010-06-02", "3 Write thank-you t:2010-06-10", "4 (B) Clean t:2010-05-30", "5 Donate to LSF t:2010-06-02", "6 (A) t:2010-05-30 Pick up dry cleaning", "2 (C) Call Chris Johnson t:2010-06-01" ); That first number is the task's ID. If a task has ([A-Z]) next to, that defines the task's priority. What I want to do is sort the tasks array in a way that places the prioritized items first (and in order): @todos = ( "1 (A) Complete online final @evm4700 t:2010-06-02", "6 (A) t:2010-05-30 Pick up dry cleaning", "4 (B) Clean t:2010-05-30", "2 (C) Call Chris Johnson t:2010-06-01" "3 Write thank-you t:2010-06-10", "5 Donate to LSF t:2010-06-02", ); I cannot use a regular sort() because of those IDs next to the tasks, so I'm assuming that some sort of customized sorting subroutine is needed. However, my knowledge of how to do this efficiently in perl is minimal. Thanks, all.

  • Declaring more than one SPIM array causes a syntax error

    - by Zack
    Below is the beginning of a chunk of SPIM code: .data a: .space 20 b: .space 20 .text set_all: sw $ra,0($sp) li $t0,0 li $t1,10 ............ Unfortunately, the second array I declare ('b') causes the SPIM interpreter to spit out: spim: (parser) syntax error on line 3 of file spim.out b: .space 20 ^ Similar code works when I only have one array -- it seems to be the second that screws it up. I've prodded at it but can't figure out what it is about that statement that makes it break. Any thoughts? Thanks for any insight.

  • coding an array in a class library and make a call to it C#

    - by eddy
    I'm new to C#, so this may be a basic question. What I need to do is put an array such as the one below in a class library and then make a call to it. So I'd want the aproprate picture to appear via the class and this array. I know there's a much simpler way to make certain pictures appear, but this is a requirement for the project. It's an asp.NET website in C#. string[] PictureArray; PictureArray = new string[3]; PictureArray[0] = "~/pics/grl.jpg"; PictureArray[1] = "~/pics/pop.jpg"; PictureArray[2] = "~/pics/str.jpg"; PictureArray[3] = "~/pics/unk.jpg";

  • Wrapping allocated output parameters with a scoped_ptr/array

    - by Danra
    So, I have some code which looks like this: byte* ar; foo(ar) // Allocates a new[] byte array for ar ... delete[] ar; To make this safer, I used a scoped_array: byte* arRaw; scoped_array ar; foo(arRaw); ar.reset(arRaw); ... // No delete[] The question is, Is there any existing way to do this using just the scoped_array, without using a temporary raw array? I can probably write an in-place "resetter" class, just wondering if the functionality exists and I'm missing it. Thanks, Dan

  • Basic Array Iteration in Ruby

    - by michaelmichael
    What's a better way to traverse an array while iterating through another array? For example, if I have two arrays like the following: names = [ "Rover", "Fido", "Lassie", "Calypso"] breeds = [ "Terrier", "Lhasa Apso", "Collie", "Bulldog"] Assuming the arrays correspond with one another - that is, Rover is a Terrier, Fido is a Lhasa Apso, etc. - I'd like to create a dog class, and a new dog object for each item: class Dog attr_reader :name, :breed def initialize(name, breed) @name = name @breed = breed end end I can iterate through names and breeds with the following: index = 0 names.each do |name| dog = Dog.new("#{name}", "#{breeds[index]}") index = index.next end However, I get the feeling that using the index variable is the wrong way to go about it. What would be a better way?

  • two arrays defining 2d coordinates, as array indices, in matlab/octave

    - by Jason
    Hi, I have a 2D array, call it 'A'. I have two other 2D arrays, call them 'ix' and 'iy'. I would like to create an output array whose elements are the elements of A at the index pairs provided by x_idx and y_idx. I can do this with a loop as follows: for i=1:nx for j=1:ny output(i,j) = A(ix(i,j),iy(i,j)); end end How can I do this without the loop? If I do output = A(ix,iy), I get the value of A over the whole range of (ix)X(iy). Thank you, Jason

  • How to populate an array with recordset data

    - by Curtis Inderwiesche
    I am attempting to move data from a recordset directly into an array. I know this is possible, but specifically I want to do this in VBA as this is being done in MS Access 2003. Typically I would do something like the following to archive this: Dim vaData As Variant Dim rst As ADODB.Recordset ' Pull data into recordset code here... ' Populate the array with the whole recordset. vaData = rst.GetRows What differences exist between VB and VBA which makes this type of operation not work? What about performance concerns? Is this an "expensive" operations?

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • help with array

    - by JohnWong
    You will write a program that evaluates the integral of sin(x) using the left-hand rectangle rule with 2000 subintervals, over 10 intervals. The intervals to test are [0, 1), [1, 2), …, [8, 9), [9, 10). You will declare an array of type double that can hold 10 elements, and you will use this array to hold all 10 results you get from evaluating each interval. I am in testing my code, what should be the output? For example, [0, 1)? Any idea? Thanks.

  • How to write two-dimensional array to xml in Scala 2.8.0

    - by Shadowlands
    The following code (copied from a question from about a year ago) works fine under Scala 2.7.7, but does not behave correctly under Scala 2.8.0 (Beta 1, RC8). import scala.xml class Person(name : String, age : Int) { def toXml(): xml.Elem = <person><name>{ name }</name><age>{ age }</age></person> } def peopleToXml(people: Array[Person]): xml.Elem = { <people>{ for {person <- people} yield person.toXml }</people> } val data = Array(new Person("joe",40), new Person("mary", 35)) println(peopleToXml(data)) The output (according to 2.7.7) should be: <people><person><name>joe</name><age>40</age></person><person><name>mary</name><age>35</age></person></people> but instead comes out as: <people>\[Lscala.xml.Elem;@17821782</people> How do I get this to behave as it did in 2.7.x?

  • Sending an array of complex objects in the get string in C# ASP.NET MVC

    - by Mr Snuffle
    Hi, I want to send an array of objects in the get request string. I know this isn't the optimal solution, but I really just want to get this up and running. If I have a class, something like this public class Data { public int a { get; set; } public int b { get; set; } } public class RequestViewData { public IList<Data> MyData { get; set; } } I thought I could bind the MVC route to a web request like this http://localhost:8080/Request?MyData[0].a=1&MyData[0].b=2&MyData[1].a=3&[MyData[1].b=4 But all this does is create an array of two data objects without populating the values 1,2, 3 or 4. Is there a way to bind complex objects arrays?

  • Powershell Select-Object from array not working

    - by Andrew
    I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

  • Better method for flipping multidimensional array?

    - by sudowned
    I've retrieved some data from the database, which is in the following structure: [0] [item_id] = 197 [dice_chat_css] = "foo" [dice_image] = "bar.png" [1] [item_id] = 128 [dice_chat_css] = "foo" [dice_image] = "bar.png" The most convenient and computationally inexpensive way for me to pass this data to the rest of my (PHP) application is with item_id as the index, because it saves having to loop over the array to look up values. If this was a flat array, I could accomplish this trivially with array_flip, but since it isn't, it's my pick of using either the multidimensional array_flip listed in the comments on PHP.net, or roll my own logic: for ($i = 0; $i < sizeOf($r); $i++){ $s[$r[$i]['item_id']]['dice_image'] = $r[$i]['dice_image']; $s[$r[$i]['item_id']]['dice_chat_css'] = $r[$i]['dice_chat_css']; } I know it's simple, but it feels like I'm reinventing the wheel here. Is there an accepted, more optimized method available or am I being weird about this?
