  • NSTableView binding problem

    - by Niklas Ottosson
    I have only just started with XCode (v3.2.2) and Interface Builder and have run into a problem. Here is what I have done: I have made a class to be the datasource of a NSTableView: @interface TimeObjectsDS : NSControl { IBOutlet NSTableView * idTableView; NSMutableArray * timeObjects; } @property (assign) NSMutableArray * timeObjects; @property (assign) NSTableView * idTableView; - (id) init; - (void) dealloc; - (void) addTimeObject: (TimeObj *)timeObject; - (int) count; // NSTableViewDataSource Protocol functions - (int)numberOfRowsInTableView:(NSTableView *)tableView; - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row: (int)row; I have then bound my NSTableView in the View to this datasource like so: I have also bound the View NSTableView to the Model idTableView variable in Interface Builder seen above In the init function I add a element to the mutable array. This is displayed correctly in the NSTableView when I run the application. However when I add another element to the array (of same type as in init) and try to call [idTableView reloadData] on the View nothing happens. In fact the Model idTableView is null. When printing the variable with NSLog(@"idTableView: %@", idTableView) I get "idTableView: (null)" Im runing out of ideas how to fix this. Any ideas to what I could do to fix the binding?

  • How do I best display CheckBoxes in SQL Server Reporting Services?

    - by Yadyn
    One of the many quirks of Reporting Services we've run across is the complete and utter lack of a CheckBox control or even something remotely similar. We have a form that should appear automatically filled out based on information pulled from a database. We have several bit datatype fields. Printing out "True" or "False" just looks silly, as this is supposed to look like a form that has been auto-filled out, so we want to have a series of checkboxes and labels that are either checked or unchecked. We are running SSRS 2005 but I'm not aware of SSRS 2008 having added a CheckBox control. Even if it did, we'd need to have an alternative for the time being. The best we've found so far is: use Wingdings use images use text boxes with borders and print a blank/space or a capital X All three approaches require IIF expression shenanigans. The Wingdings approach seemed to work acceptably, and was the most aesthetically pleasing except that for whatever reason it didn't always print correctly. More importantly, PDF exports, also for whatever reason, converted all fonts (generally) to Arial and so we got funky letters instead of the Windings dingbats. Images, being a pixel-based raster, don't do so well when printed along side vector stuff like text. Unless handled carefully, they tend to stretch, pixelate, and do other unprofessional looking things. While these methods do work (some with limitations as mentioned above) none of them are particularly elegant. Are we missing something obvious? Not so obvious? Does someone at Microsoft have a good reason why such a control was not provided in SSRS 2000, let alone 2 versions and 8 years later? This can't be the first time this issue has come up...

  • Troubles Iterating Over A HashMap with JSF, MyFaces & Facelets

    - by Lee Theobald
    Hi all, I'm having some trouble looping over a HashMap to print out it's values to the screen. Could someone double check my code to see what I'm doing wrong. I can't seem to find anything wrong but there must be something. In a servlet, I am adding the following to the request: Map<String, String> facetValues = new HashMap<String, String>(); // Filling the map req.setAttribute(facetField.getName(), facetValues); In one case "facetField.getName()" evaluates to "discipline". So in my page I have the following: <ui:repeat value="${requestScope.discipline}" var="item"> <li>Item: <c:out value="${item}"/>, Key: <c:out value="${item.key}"/>, Value: <c:out value="${item.item}"/></li> </ui:repeat> The loop is ran once but all the outputs are blank?!? I would have at least expected something in item if it's gone over the loop once. Checking the debug popup for Facelets, discipline is there and on the loop. Printing it to the screen results in something that looks like a map to me (I've shortened the output) : {300=0, 1600=0, 200=0, ... , 2200=0} I've also tried with a c:forEach but I'm getting the same results. So does anyone have any ideas where I'm going wrong? Thanks for any input, Lee

  • Problem retrieving values from Zend_Form_SubForms - no values returned

    - by anu iyer
    I have a Zend_Form that has 4 or more subforms. /** Code Snippet **/ $bigForm = new Zend_Form(); $littleForm1 = new Form_LittleForm1(); $littleForm1->setMethod('post'); $littleForm2 = new Form_LittleForm2(); $littleForm2->setMethod('post'); $bigForm->addSubForm($littleForm1,'littleForm1',0); $bigForm->addSubForm($littleForm2,'littleForm2',0); On clicking the 'submit' button, I'm trying to print out the values entered into the forms, like so: /** Code snippet, currently not validating, just printing **/ if($this-_request-getPost()){ $formData = array(); foreach($bigForm->getSubForms() as $subForm){ $formData = array_merge($formData, $subForm->getValues()); } /* Testing */ echo "<pre>"; print_r($formData); echo "</pre>"; } The end result is that - all the elements in the form do get printed, but the values entered before posting the form don't get printed. Any thoughts are appreciated...I have run around circles working on this! Thanks in advance!

  • how i print the values from NSArray objects in CGContextShowTextAtpoint()?

    - by Rajendra Bhole
    Hi, I developing an application in which i want to print the values on a line interval, for that i used NSArray with multiple objects and those object i passing into CGContextShowTextAtPoint() method. The code is. CGContextMoveToPoint(ctx, 30.0, 200.0); CGContextAddLineToPoint(ctx, 30.0, 440.0); NSArray *hoursInDays = [[NSArray alloc] initWithObjects:@"0",@"1",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12", nil]; int intHoursInDays = 0; for(float y = 400.0; y >= 200.0; y-=18, intHoursInDays++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, 28, y); CGContextAddLineToPoint(ctx, 32, y); CGContextSelectFont(ctx, "Helvetica", 12.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); NSString *arrayDataForYAxis = [hoursInDays objectAtIndex:intHoursInDays]; CGContextShowTextAtPoint(ctx, 10.0, y+20, [arrayDataForYAxis UTF8String], strlen((char *)arrayDataForYAxis)); CGContextStrokePath(ctx); } The above code is executed but it given me output is {oo, 1o,2o,...........11}, i want the output is {0,1,2,3...........11,12}. The above code given me one extra character "o" after single digit.I think the problem i meet near the parameters type casting of 5th parameter inside the method of CGContextShowTextAtpoint CGContextShowTextAtpoint(). How i resolve the problem of type casting for printing the objects of NSSArray in CGContextShowTextAtpoint() method??????????????

  • RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

    - by Ed
    I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

  • Vector of pointers to base class, odd behaviour calling virtual functions

    - by Ink-Jet
    I have the following code #include <iostream> #include <vector> class Entity { public: virtual void func() = 0; }; class Monster : public Entity { public: void func(); }; void Monster::func() { std::cout << "I AM A MONSTER" << std::endl; } class Buddha : public Entity { public: void func(); }; void Buddha::func() { std::cout << "OHMM" << std::endl; } int main() { const int num = 5; // How many of each to make std::vector<Entity*> t; for(int i = 0; i < num; i++) { Monster m; Entity * e; e = &m; t.push_back(e); } for(int i = 0; i < num; i++) { Buddha b; Entity * e; e = &b; t.push_back(e); } for(int i = 0; i < t.size(); i++) { t[i]->func(); } return 0; } However, when I run it, instead of each class printing out its own message, they all print the "Buddha" message. I want each object to print its own message: Monsters print the monster message, Buddhas print the Buddha message. What have I done wrong?

  • CURL & web.py: transfer closed with outstanding read data remaining

    - by Richard J
    Hi Folks, I have written a web.py POST handler, thus: import web urls = ('/my', 'Test') class Test: def POST(self): return "Here is your content" app = web.application(urls, globals()) if __name__ == "__main__": app.run() When I interact with it using Curl from the command line I get different responses depending on whether I post it any data or not: curl -i -X POST http://localhost:8080/my HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:42:41 GMT Server: CherryPy/3.1.2 WSGI Server Here is your content (Posting of no data to the server gives me back the "Here is your content" string) curl -i -X POST --data-binary "@example.zip" http://localhost:8080/my HTTP/1.1 100 Content-Length: 0 Content-Type: text/plain HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:43:47 GMT Server: CherryPy/3.1.2 WSGI Server curl: (18) transfer closed with outstanding read data remaining (Posting example.zip to the server results in this error) I've scoured the web.py documentation (what there is of it), and can't find any hints as to what might be going on here. Possibly something to do with 100 continue? I tried writing a python client which might help clarify: h1 = httplib.HTTPConnection('localhost:8080') h1.request("POST", "http://localhost:8080/my", body, headers) print h1.getresponse() body = the contents of the example.zip, and headers = empty dictionary. This request eventually timed out without printing anything, which I think exonerates curl from being the issue, so I believe something is going on in web.py which isn't quite right (or at least not sufficiently clear) Any web.py experts got some tips? Cheers, Richard

  • Export Multiple Crystal Reports ASP.NET

    - by AProgrammer
    Hey all, I want to export 2 different reports when I click an Export button. The problem is the routine only fires once and I only get one report to print out. Am I doing something wrong?

  • Is there a programming toolkit for converting "any file type" to a TIFF image?

    - by Ryan
    Hello, I've written several variations of a program. The purpose of the program is to convert "any file type" to a TIFF image represenation of that file, as if it were being printed using a printer. I'm currently using a third party printer driver that I send files to, and it outputs a TIFF image. This is nice, but it requires me to use Office Interop files, and interact with each individual processing application in order to print the files. I had previously tried a toolkit, called Apose .NET, which did not rely on Office Interop, and did not require any printer driver. It did the conversion all on its own and would create a TIFF image. The problem with Aspose .NET was that it did not support a wide variety of input file types. Most notably, it can't do Visio files. My project calls for the ability to create a TIFF image for virtually "any file type". (excluding exes, music files, and stuff) I know that finding something that handles literally any file type is probably not a very feasible task, so I figure if it can at least handle all the Office file types, Adobe types, and other major standard file types, then I can write a custom extension parsing module that uses those processing applications to do the printing of any file type that can be viewed using those applications. So, does anyone know of a toolkit that can do this? Preferably one that does not rely on Office or a printer driver. It does not have to be free, or open source. Or, if you know of an amazing printer driver that does this, I'm open to that too. Thanks in advance, Ryan

  • Doctesting functions that receive and display user input - Python (tearing my hair out)

    - by GlenCrawford
    Howdy! I am currently writing a small application with Python (3.1), and like a good little boy, I am doctesting as I go. However, I've come across a method that I can't seem to doctest. It contains an input(), an because of that, I'm not entirely sure what to place in the "expecting" portion of the doctest. Example code to illustrate my problem follows: """ >>> getFiveNums() Howdy. Please enter five numbers, hit <enter> after each one Please type in a number: Please type in a number: Please type in a number: Please type in a number: Please type in a number: """ import doctest numbers = list() # stores 5 user-entered numbers (strings, for now) in a list def getFiveNums(): print("Howdy. Please enter five numbers, hit <enter> after each one") for i in range(5): newNum = input("Please type in a number:") numbers.append(newNum) print("Here are your numbers: ", numbers) if __name__ == "__main__": doctest.testmod(verbose=True) When running the doctests, the program stops executing immediately after printing the "Expecting" section, waits for me to enter five numbers one after another (without prompts), and then continues. As shown below: I don't know what, if anything, I can place in the Expecting section of my doctest to be able to test a method that receives and then displays user input. So my question (finally) is, is this function doctestable?

  • How to implement a python REPL that nicely handles asynchronous output?

    - by andy
    I have a Python-based app that can accept a few commands in a simple read-eval-print-loop. I'm using raw_input('> ') to get the input. On Unix-based systems, I also import readline to make things behave a little better. All this is working fine. The problem is that there are asynchronous events coming in, and I'd like to print output as soon as they happen. Unfortunately, this makes things look ugly. The " " string doesn't show up again after the output, and if the user is halfway through typing something, it chops their text in half. It should probably redraw the user's text-in-progress after printing something. This seems like it must be a solved problem. What's the proper way to do this? Also note that some of my users are Windows-based. TIA Edit: The accepted answer works under Unixy platforms (when the readline module is available), but if anyone knows how to make this work under Windows, it would be much appreciated!

  • Perl, share package variable without Export

    - by Mike
    I'm creating a group of Perl scripts, and I would like to have one package store a group of constants. I don't want to export them using Exporter because there will be quite a few and I don't want to pollute the namespace. Since there will be so many, I don't want to require the user to be forced to manually specify which they will be using. I think the best way to just use the packagename::var syntax, however it doesn't seem to be working as I expect it to. I illustrate this problem in the below code This is settings.pm, the module that will hold the global settings #!/usr/bin/perl #settings.pm use strict; use warnings; package settings; our $foo="hello world"; 1; Below is the main script #!/usr/bin/perl #script.pl use strict; use warnings; use settings; print settings::$foo; It gives this error message instead or printing hello world Bad name after settings:: at ./script.pl line 8.

  • Function that prints something to std::ostream and returns std::ostream?

    - by dehmann
    I want to write a function that outputs something to a ostream that's passed in, and return the stream, like this: std::ostream& MyPrint(int val, std::ostream* out) { *out << val; return *out; } int main(int argc, char** argv){ std::cout << "Value: " << MyPrint(12, &std::cout) << std::endl; return 0; } It would be convenient to print the value like this and embed the function call in the output operator chain, like I did in main(). It doesn't work, however, and prints this: $ ./a.out 12Value: 0x6013a8 The desired output would be this: Value: 12 How can I fix this? Do I have to define an operator<< instead? UPDATE: Clarified what the desired output would be. UPDATE2: Some people didn't understand why I would print a number like that, using a function instead of printing it directly. This is a simplified example, and in reality the function prints a complex object rather than an int.

  • Manipulating jQuery to retrieve the onclick function of an item which lies directly below the curren

    - by Stevie Jenowski
    First off, I want to thank you for looking into my question as I really do appreciate your time. I've built a list of items using php by having a foreach loop cycle through an associative array printing the array data as parameters of an onclick function call and gives each item it cycles through an ID of $thecount. All items retrieved have the same parent div and calls the very same onclick function, only with 11 different parameters. My question is how do I go about calling the onClick("function();") of an item directly below the current focus, making it the new focus, only without a physical click? If this is confusing to you whatsoever, I'm essentially building a dynamic playlist, and I've already implemented the listener for when the player's current item has finished playing, Now I'm having trouble grasping how I'd go about having the next item in the list become the new focus while also calling it's specific onClick() function once the player returns that it has finished with the current file. All without any user interaction besides the initial play call. If it helps I'm using the most recent release of Longtails' JW Player and once again thank you very much for your time!

  • CS 50- Pset 1 Mario Program

    - by boametaphysica
    the problem set asks us to create a half pyramid using hashes. Here is a link to an image of how it should look- I get the idea and have written the program until printing the spaces (which I have replaced by "_" just so that I can test the first half of it. However, when I try to run my program, it doesn't go beyond the do-while loop. In other words, it keeps asking me for the height of the pyramid and does not seem to run the for loop at all. I've tried multiple approaches but this problem seems to persist. Any help would be appreciated! Below is my code- # include <cs50.h> # include <stdio.h> int main(void) { int height; do { printf("Enter the height of the pyramid: "); height = GetInt(); } while (height > 0 || height < 24); for (int rows = 1; rows <= height, rows++) { for (int spaces = height - rows; spaces > 0; spaces--) { printf("_"); } } return 0; } Running this program yields the following output- Enter the height of the pyramid: 11 Enter the height of the pyramid: 1231 Enter the height of the pyramid: aawfaf Retry: 12 Enter the height of the pyramid:

  • Bash script to log in over SSH

    - by user1042928
    Sorry if this seems like a dumb question but I am just learning bash scripting. For a school project we need to code an RTX that runs in Unix. It runs as a process in terminal and takes in user input and then prints it to the screen. I want to write a bash script to test that it can respond to lots of quick user input without overflowing or failing. My main problem is that once the RTX starts the bash script will stop on that line until the RTX terminates and only then print the loop to the terminal (instead of printing it to the RTX prompt as I intend it to). I have tried running the RTX in the background but that didn't work. I need to find a way to redirect input to the RTX while it is still running with a bash script. Google searches didn't come up with examples that I understood/could adapt. Any help is appreciated. #!/bin/bash # declare STRING variable STRING="RTX Worked =D" #Start the rtx in a new process, stuck on this line until rtx terminates. ./main #Somehow redirect io to the rtx. for i in `seq 1 100`; do echo $i echo " \n" done echo $STRING

  • Why does my ActivePerl program report 'Sorry. Ran out of threads'?

    - by Zaid
    Tom Christiansen's example code (à la perlthrtut) is a recursive, threaded implementation of finding and printing all prime numbers between 3 and 1000. Below is a mildly adapted version of the script #!/usr/bin/perl # adapted from prime-pthread, courtesy of Tom Christiansen use strict; use warnings; use threads; use Thread::Queue; sub check_prime { my ($upstream,$cur_prime) = @_; my $child; my $downstream = Thread::Queue->new; while (my $num = $upstream->dequeue) { next unless ($num % $cur_prime); if ($child) { $downstream->enqueue($num); } else { $child = threads->create(\&check_prime, $downstream, $num); if ($child) { print "This is thread ",$child->tid,". Found prime: $num\n"; } else { warn "Sorry. Ran out of threads.\n"; last; } } } if ($child) { $downstream->enqueue(undef); $child->join; } } my $stream = Thread::Queue->new(3..shift,undef); check_prime($stream,2); When run on my machine (under ActiveState & Win32), the code was capable of spawning only 118 threads (last prime number found: 653) before terminating with a 'Sorry. Ran out of threads' warning. In trying to figure out why I was limited to the number of threads I could create, I replaced the use threads; line with use threads (stack_size => 1);. The resultant code happily dealt with churning out 2000+ threads. Can anyone explain this behavior?

  • Munging non-printable characters to dots using string.translate()

    - by Jim Dennis
    So I've done this before and it's a surprising ugly bit of code for such a seemingly simple task. The goal is to translate any non-printable character into a . (dot). For my purposes "printable" does exclude the last few characters from string.printable (new-lines, tabs, and so on). This is for printing things like the old MS-DOS debug "hex dump" format ... or anything similar to that (where additional whitespace will mangle the intended dump layout). I know I can use string.translate() and, to use that, I need a translation table. So I use string.maketrans() for that. Here's the best I could come up with: filter = string.maketrans( string.translate(string.maketrans('',''), string.maketrans('',''),string.printable[:-5]), '.'*len(string.translate(string.maketrans('',''), string.maketrans('',''),string.printable[:-5]))) ... which is an unreadable mess (though it does work). From there you can call use something like: for each_line in sometext: print string.translate(each_line, filter) ... and be happy. (So long as you don't look under the hood). Now it is more readable if I break that horrid expression into separate statements: ascii = string.maketrans('','') # The whole ASCII character set nonprintable = string.translate(ascii, ascii, string.printable[:-5]) # Optional delchars argument filter = string.maketrans(nonprintable, '.' * len(nonprintable)) And it's tempting to do that just for legibility. However, I keep thinking there has to be a more elegant way to express this!

  • Margin on the top in LaTex

    - by Tim
    I am now writing a thesis which is required to have 1 and half inches on the left or binding side, and 1 inch on the other three sides. I just have my print-out checked in the binding office and I was told the margins are not okay, especially the one on the top is not enough, a little less than 1 inch. See the figure below: I wonder which commands are responsible for the margins on the four sides, especially for the one on the top? I provide links to two files I believe that control the layout and format of the thesis:jhu12.clo and thesis.cls. Or instead of modifying the LaTex files, is thre some setting when printing the pdf file to control these margins on the print-out? Thanks and regards! EDIT: This is the print-out of command \layout It shows "one inch + \voffset" for the top (the NO. 2 item). But the staff at the binding office use his ruler to show it is less than 1 inch. How to adjust the margins in LaTex then? Thanks!

  • Grails UrlMappings with .html

    - by Glennn
    I'm developing a Grails web application (mainly as a learning exercise). I have previously written some standard Grails apps, but in this case I wanted to try creating a controller that would intercept all requests (including static html) of the form: <a href="/testApp/testJsp.jsp">test 1</a> <a href="/testApp/testGsp.gsp">test 2</a> <a href="/testApp/testHtm.htm">test 3</a> <a href="/testApp/testHtml.html">test 4</a> The intent is to do some simple business logic (auditing) each time a user clicks a link. I know I could do this using a Filter (or a range of other methods), however I thought this should work too and wanted to do this using a Grails framework. I set up the Grail UrlMappings.groovy file to map all URLs of that form (/$myPathParam?) to a single controller: class UrlMappings { static mappings = { "/$controller/$action?/$id?"{ constraints { } } "/$path?" (controller: 'auditRecord', action: 'showPage') "500"(view:'/error') } } In that controller (in the appropriate "showPage" action) I've been printing out the path information, for example: def showPage = { println "params.path = " + params.path ... render(view: resultingView) } The results of the println in the showPage action for each of my four links are testJsp.jsp testGsp.gsp testHtm.htm testHtml Why is the last one "testHtml", not "testHtml.html"? In a previous (Stack Overflow query) Olexandr encountered this issue and was advised to simply concatenate the value of request.format - which, indeed, does return "html". However request.format also returns "html" for all four links. I'm interested in gaining an understanding of what Grails is doing and why. Is there some way to configure Grails so the params.path variable in the controller shows "testHtml.html" rather than stripping off the "html" extension? It doesn't seem to remove the extension for any other file type (including .htm). Is there a good reason it's doing this? I know that it is a bit unusual to use a controller for static html, but still would like to understand what's going on.

  • Tableview not updating correctly after adding person

    - by tazboy
    I have to be missing something simple here but it escapes me. After the user enters a new person to a mutable array I want to update the table. The mutable array is the datasource. I believe my issue lies within cellForRowAtIndexPath. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { TextFieldCell *customCell = (TextFieldCell *)[tableView dequeueReusableCellWithIdentifier:@"TextCellID"]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"]; if (indexPath.row == 0) { if (customCell == nil) { NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"TextFieldCell" owner:nil options:nil]; for (id currentObject in nibObjects) { if ([currentObject isKindOfClass:[TextFieldCell class]]) customCell = (TextFieldCell *)currentObject; } } customCell.nameTextField.delegate = self; cell = customCell; } else { if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; cell.textLabel.text = [[self.peopleArray objectAtIndex:indexPath.row-1] name]; NSLog(@"PERSON AT ROW %d = %@", indexPath.row-1, [[self.peopleArray objectAtIndex:indexPath.row-1] name]); NSLog(@"peopleArray's Size = %d", [self.peopleArray count]); } } return cell; } When I first load the view everything is great. This is what prints: PERSON AT ROW 0 = Melissa peopleArray's Size = 2 PERSON AT ROW 1 = Dave peopleArray's Size = 2 After I add someone to that array I get this: PERSON AT ROW 1 = Dave peopleArray's Size = 3 PERSON AT ROW 2 = Tom peopleArray's Size = 3 When I add a second person I get: PERSON AT ROW 2 = Tom peopleArray's Size = 4 PERSON AT ROW 3 = Ralph peopleArray's Size = 4 Why is not printing everyone in the array? This pattern continues and it only ever prints two people, and it's always the last two people. What the heck am I missing?

  • Can a standalone ruby script (windows and mac) reload and restart itself?

    - by user30997
    I have a master-workers architecture where the number of workers is growing on a weekly basis. I can no longer be expected to ssh or remote console into each machine to kill the worker, do a source control sync, and restart. I would like to be able to have the master place a message out on the network that tells each machine to sync and restart. That's where I hit a roadblock. If I were using any sane platform, I could just do: exec('ruby', __FILE__) ...and be done. However, I did the following test: p Process.pid sleep 1 exec('ruby', __FILE__) ...and on Windows, I get one ruby instance for each call to exec. None of them die until I hit ^C on the window in question. On every platform I tried this on, it is executing the new version of the file each time, which I have verified this by making simple edits to the test script while the test marched along. The reason I'm printing the pid is to double-check the behavior I'm seeing. On windows, I am getting a different pid with each execution - which I would expect, considering that I am seeing a new process in the task manager for each run. The mac is behaving correctly: the pid is the same for every system call and I have verified with dtrace that each run is trigging a call to the execve syscall. So, in short, is there a way to get a windows ruby script to restart its execution so it will be running any code - including itself - that has changed during its execution? Please note that this is not a rails application, though it does use activerecord.
