  • jquery pagination plugin doesn't quite work right for me...

    - by Pandiya Chendur
    My page has the following jquery statements, <script type="text/javascript"> $(document).ready(function() { getRecordspage(1, 5); }); </script> It works fine but how to add callback function to my pagination( callback://)? function getRecordspage(curPage, pagSize) { $.ajax({ type: "POST", url: "Default.aspx/GetRecords", data: "{'currentPage':" + curPage + ",'pagesize':" + pagSize + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(jsonObj) { var strarr = jsonObj.d.split('##'); var jsob = jQuery.parseJSON(strarr[0]); var divs = ''; $.each(jsob.Table, function(i, employee) { divs += '<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>'; }); $("#ResultsDiv").append(divs).show('slow'); $(".pager").pagination(strarr[1], { // callback function call to this method current_page: curPage-1, items_per_page: '5', num_display_entries : '5', next_text: 'Next', prev_text: 'Prev', num_edge_entries: '1' }); } }); } On the initial page load i get all divs with page numbers generated but when i click the next page number nothing happens because callback is not configured....Because my callback function has to call the same method with the current anchor tag which is clicked... Any suggestion how to get this done.......

  • I just wanted to DES 4096 bytes of data with a 128 bits key...

    - by badp
    ...and what the nice folks at OpenSSL gratiously provide me with is this. :) Now, since you shouldn't be guessing when using cryptography, I come here for confirmation: what is the function call I want to use? What I understood A 128 bits key is 16 byte large, so I'll need double DES (2 × 8 byte). This leaves me with only a few function calls: void DES_ede2_cfb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num, int enc); void DES_ede2_cbc_encrypt(const unsigned char *input, unsigned char *output, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int enc); void DES_ede2_cfb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num, int enc); void DES_ede2_ofb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num); In this case, I guess the function I want to call DES_ede2_cfb64_encrypt, although I'm not so sure -- I definitely don't need padding here and I'd have to care about what ivec and num are, and how I want to generate them... What am I missing?

  • How to debug python del self.callbacks[s][cid] keyError when the error message does not indicate where in my code the error is

    - by lkloh
    In a python program I am writing, I get an error saying Traceback (most recent call last): File "/Applications/Canopy.app/appdata/canopy-1.4.0.1938.macosx- x86_64/Canopy.app/Contents/lib/python2.7/lib-tk/Tkinter.py", line 1470, in __call__ return self.func(*args) File "/Users/lkloh/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/backends/backend_tkagg.py", line 413, in button_release_event FigureCanvasBase.button_release_event(self, x, y, num, guiEvent=event) File "/Users/lkloh/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/backend_bases.py", line 1808, in button_release_event self.callbacks.process(s, event) File "/Users/lkloh/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/cbook.py", line 525, in process del self.callbacks[s][cid] KeyError: 103 Do you have any idea how I can debug this/ what could be wrong?

  • Response Redirect - Open Link in New Window

    - by bacis09
    First, I've taken the time to review this question which seems to be the most similar, however, the solution that seems to have been selected will not work in my scenario.Not to mention I worry about some of the comments claiming it to be brittle or an inadequate solution. http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window -We have an XML document which basically contains all of the information for a Side menu. -We have numerous URLS which are stored in a constants class. -One of the elements in a string of XML (well call it label) is used to determine if the menu item is created as a LinkButton or a Label. -Links use a custom user control that is used standard for all links across the application (why suggestion on similar thread doesn't work - I don't want all links to open in a new window - just one) -One of the elements in a string of XML (well call it function) is used in a Switch statement to generate our links using Response Redirect. It may look something like this. switch (function) { case goto 1: string url; if (user_group == 1) { url = Constants.CONSTANT1 } else { url = Constants.CONSTANT2 } Response.Redirect(url) case goto 2: ...... default: ...... break; } Given this scenario, I'm trying to find the best way to quickly open a New Window, when a specific case in this switch statement is met. Can it be done with Response Redirect (this seems to be arguable - people say no it can't, yet other people say they have made it work)? If not, what alternative can work here?

  • Java queue and multi-dimension array

    - by javaLearner.java
    First of all, this is my code (just started learning java): Queue<String> qe = new LinkedList<String>(); qe.add("b"); qe.add("a"); qe.add("c"); qe.add("d"); qe.add("e"); My question: Is it possible to add element to the queue with two values, like: qe.add("a","1"); // where 1 is integer So, that I know element "a" have value 1. If I want to add a number let say "2" to element a, I will have like a = 3. If this cant be done, what else in java classes that can handle this? I tried to use multi-dimention array, but its kinda hard to do the queue, like pop, push etc. (Maybe I am wrong) How to call specific element in the queue? Like, call element a, to check its value. [Note] Please don't give me links that ask me to read java docs. I was reading, and I still dont get it. The reason why I ask here is because, I know I can find the answer faster and easier.

  • How do I automatically update hundreds of images in an HTML page using jquery?

    - by Chris
    I have an HTML page where I want to refresh a lot of images every 30 seconds after the HTML page has been downloaded. I understand how to do this with Jquery and a single image, but I want to use about 200 custom urls to determine the current image to display for over 200 images. I need to find an efficient way to have jquery call the custom url associated with each image to download the url for the needed image as it changes, and then update the image in the page when it changes. Current hyperlink example to demonstrate the custom urls. <A href="/urlThatReturnsCurrentImageURL/1234/4567">link to url for image</A> Each custom url will return an image tag like this (or any other text that makes this simpler for jquery) <img src="/static/someImage.jpg"> What is the simplest way to have jquery call the custom url for each image to download the image url, image html, or some other text that jquery can use to download the right image every 30 seconds? Please keep in mind that I will have about 200 of these on a page.

  • How can I achieve this kind of relationship (inheritance, composition, something else)?

    - by Tim
    I would like to set up a foundation of classes for an application, two of which are person and student. A person may or may not be a student and a student is always a person. The fact that a student “is a” person led me to try inheritance, but I can't see how to make it work in the case where I have a DAO that returns an instance of person and I then want to determine if that person is a student and call student related methods for it. class Person { private $_firstName; public function isStudent() { // figure out if this person is a student return true; // (or false) } } class Student extends Person { private $_gpa; public function getGpa() { // do something to retrieve this student's gpa return 4.0; // (or whatever it is) } } class SomeDaoThatReturnsPersonInstances { public function find() { return new Person(); } } $myPerson = SomeDaoThatReturnsPersonInstances::find(); if($myPerson->isStudent()) { echo 'My person\'s GPA is: ', $myPerson->getGpa(); } This obviously doesn't work, but what is the best way to achieve this effect? Composition doesn't sond right in my mind because a person does not “have a” student. I'm not looking for a solution necessarily but maybe just a term or phrase to search for. Since I'm not really sure what to call what I'm trying to do, I haven't had much luck. Thank you!

  • .htaccess trickery multi-language website

    - by user1658741
    I have a website right now that uses two languages (french and english) The way it works right now is that if someone goes to mysite.com/folder/file.php for example, file.php is simply a script that figures out which language to use, get's it's own path and filename(file.php) and serves up mysite.com/en/folder/file.php (if the language is english). However what shows up in the URL is still mysite.com/folder/file.php. For any folder and any file the same script is used. If I want to add a new file I have to add the file to the folder the user types into the browser as well to the en and fr folders. Could I do some .htaccess trickery so that whatever URL is typed, one .php file gets open that checks the language and what folder/file was requested and then serves up the correct language file? here's the php file that is served up for any files in the URL. <?php // Get current document path which is mirrored in the language folders $docpath = $_SERVER['PHP_SELF']; // Get current document name (Used when switching languages so that the same current page is shown when language is changed) $docname = GetDocName(); //call up lang.php which handles display of appropriate language webpage. //lang.php uses $docpath and $docname to give out the proper $langfile. //$docpath/$docname is mirrored in the /lang/en and /lang/fr folders $langfile = GetDocRoot()."/lang/lang.php"; include("$langfile"); //Call up the proper language file to display function GetDocRoot() { $temp = getenv("SCRIPT_NAME"); $localpath=realpath(basename(getenv("SCRIPT_NAME"))); $localpath=str_replace("\\","/",$localpath); $docroot=substr($localpath,0, strpos($localpath,$temp)); return $docroot; } function GetDocName() { $currentFile = $_SERVER["SCRIPT_NAME"]; $parts = Explode('/', $currentFile); $dn = $parts[count($parts) - 1]; return $dn; } ?>

  • Looking for an appropriate design pattern

    - by user1066015
    I have a game that tracks user stats after every match, such as how far they travelled, how many times they attacked, how far they fell, etc, and my current implementations looks somewhat as follows (simplified version): Class Player{ int id; public Player(){ int id = Math.random()*100000; PlayerData.players.put(id,new PlayerData()); } public void jump(){ //Logic to make the user jump //... //call the playerManager PlayerManager.jump(this); } public void attack(Player target){ //logic to attack the player //... //call the player manager PlayerManager.attack(this,target); } } Class PlayerData{ public static HashMap<int, PlayerData> players = new HashMap<int,PlayerData>(); int id; int timesJumped; int timesAttacked; } public void incrementJumped(){ timesJumped++; } public void incrementAttacked(){ timesAttacked++; } } Class PlayerManager{ public static void jump(Player player){ players.get(player.getId()).incrementJumped(); } public void incrementAttacked(Player player, Player target){ players.get(player.getId()).incrementAttacked(); } } So I have a PlayerData class which holds all of the statistics, and brings it out of the player class because it isn't part of the player logic. Then I have PlayerManager, which would be on the server, and that controls the interactions between players (a lot of the logic that does that is excluded so I could keep this simple). I put the calls to the PlayerData class in the Manager class because sometimes you have to do certain checks between players, for instance if the attack actually hits, then you increment "attackHits". The main problem (in my opinion, correct me if I'm wrong) is that this is not very extensible. I will have to touch the PlayerData class if I want to keep track of a new stat, by adding methods and fields, and then I have to potentially add more methods to my PlayerManager, so it isn't very modulized. If there is an improvement to this that you would recommend, I would be very appreciative. Thanks.

  • Jquery Works in FF but not IE at all

    - by Shawn
    I set up the SimpleModal plugin to work from our Ad server(Real 24/7). Essentially, attempting to make an interstitial ad. I serve a popupAd.js file from the Ad Server to our homepage(index.php), Here is the code for popupAd.js: $(document).ready(function() { $.modal('<iframe src="/welcomeAd.htm" height="525" width="562" style="border:0;" scrolling="no"/>', { closeHTML: "<a href='#' title='Close' align='right' style='color:#666>(X) Continue to website</a>", containerCss: { backgroundColor: '#fff', borderColor: "#0063dc", height: 525, padding: 0, width: 562, }, overlayCss:{ backgroundColor:"#fff", }, opacity:100, overlayClose: true }); }); This opens a modal window on the homepage which then loads welcomeAd.htm which contain nothing other than the ad call to the creative. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> <html> <head> <title>Company Name</title> <!------ AD SERVER SETUP begin ------> <!------ OAS SERVER SETUP end ------> </head> <body style="margin: 0; padding: 0; width: 100%; height: 100%"> <script type="text/javascript" language="JavaScript"> <!-- AD SERVER CALL; //--> </script> </body> </html> This all works in FF but does nothing in IE, of which I am running IE7. Also, the closeHTML doesn't show up in Safari, though, the ad does.

  • UDP: Client started before Server

    - by Chris
    I have a bit of a glitch in my game just now, everything runs fine if the server is started before the client however when the client is started before the server they never connect. This is all UDP The problem happens when the client tries to call recvfrom() before the server has started, when this happens the client never finds the server and the server never finds the client. The resulted error is a wouldblock. If I stop the client using recvfrom and start the client before the server (the client is still sending data its just not receiving it) they both find each other no problem. Whats the solution for this? The way its seems just now is that the client cannot call recvfrom without a server being active or it all falls apart. Is there a check that can be done to see if data is sitting on a certain port(data the server would send)? Or is there a better way to do this? Some Code... Server Operation - UDPSocket is a class UDPSocket.Initialise(); UDPSocket.MakeNonBlocking(); UDPSocket.Bind(LOCALPORT); int n = UDPSocket.Receive(&thePacket); if (n > 0) UDPSocket.Send(&sendPacket); Client... UDP.Initialise(); UDP.MakeNonBlocking(); UDP.SetDestinationAddress(SERVERIP, SERVERPORT); serverStatus = UDP.Receive(&recvPacket); if (serverStatus > 0) { //Do some things UDP.Send(dPacket); //Try and reconnect with server } Thanks

  • Accessing Sub functions /procedures from DPR or other function / procedure in Delphi

    - by HX_unbanned
    Hello, stackoverflowers :) As much I know - Subroutines are with Private access mode to its parent unction / procedure, right? Is there any way to access them from "outer-world" - dpr or other function / procedure in unit? Also - which way takes more calcualtion and space to compiled file? for example: function blablabla(parameter : tparameter) : abcde; procedure xyz(par_ : tpar_); begin // ... end; begin // ... end; procedure albalbalb(param : tparam) : www; begin xyz(par_ : tpar); // is there any way to make this function public / published to access it therefore enabling to call it this way? end; // all text is random. // also, is there way to call it from DPR in this manner? // in C++ this can be done by specifing access mode and/or using "Friend" class .. but in DELPHI?

  • How do I delete duplicates between two excel sheets quickly vba

    - by MainTank
    I am using vba and I have two sheets one is named "Do Not Call" and has about 800,000 rows of data in column A. I want to use this data to check column I in the second sheet, named "Sheet1". If it finds a match I want it to delete the whole row in "Sheet1". I have tailored the code I have found from a similar question here: Excel formula to Cross reference 2 sheets, remove duplicates from one sheet and ran it but nothing happens. I am not getting any errors but it is not functioning. Here is the code I am currently trying and have no idea why it is not working Option Explicit Sub CleanDupes() Dim wsA As Worksheet Dim wsB As Worksheet Dim keyColA As String Dim keyColB As String Dim rngA As Range Dim rngB As Range Dim intRowCounterA As Integer Dim intRowCounterB As Integer Dim strValueA As String keyColA = "A" keyColB = "I" intRowCounterA = 1 intRowCounterB = 1 Set wsA = Worksheets("Do Not Call") Set wsB = Worksheets("Sheet1") Dim dict As Object Set dict = CreateObject("Scripting.Dictionary") Do While Not IsEmpty(wsA.Range(keyColA & intRowCounterA).Value) Set rngA = wsA.Range(keyColA & intRowCounterA) strValueA = rngA.Value If Not dict.Exists(strValueA) Then dict.Add strValueA, 1 End If intRowCounterA = intRowCounterA + 1 Loop intRowCounterB = 1 Do While Not IsEmpty(wsB.Range(keyColB & intRowCounterB).Value) Set rngB = wsB.Range(keyColB & intRowCounterB) If dict.Exists(rngB.Value) Then wsB.Rows(intRowCounterB).delete intRowCounterB = intRowCounterB - 1 End If intRowCounterB = intRowCounterB + 1 Loop End Sub I apologize if the above code is not in a code tag. This is my first time posting code online and I have no idea if I did it correctly.

  • How to access parents' members from a inner class in WPF?

    - by black sensei
    Hello Experts! I'm trying to do scheduled operation let's say to check for user's credit left via web service call and update the user interface. i've tried with quartz.net to implement the scheduling bit.i created an inner class in the window class i need to update.That inner class has the method that calls the webservice and the result needs to be displayed back to the UI. here is an example of what i did. public partial class Window2 : Window { private int i; public Window2() { InitializeComponent(); } public class Myclass :IJob { public void Execute(JobExecutionContext context) { string result = doMyOperation(); //i'll like to call parent label member of name lblNotif //is something like parent.lblNotif.Content = result; //possible? } public string doMyOperation() { //calling the wermethod to retreive user's balance return result = service.GetUsersBalace(user); } } } Well the quartz bit is working and this post is not about quartz. here are my questions Question 1 : How is it possible to access Window2 controls, for instace lable lblNotif? Question 2 : If my thinking about this is wrong, what is done as best practice to solve my kind of problem, where an application need to do an operation let's say every 5mn and update the the UI. Question 3 : i at first tried to use the backgroundworker and i felt like i can't do the scheduling bit with it.Is that correct or i'm wrong. thanks for those who commented already and sorry for those who didn't get the meaning of my post.I hope this will be a bit clearer.Thanks for reading

  • Dispose, when is it called?

    - by Snake
    Consider the following code: namespace DisposeTest { using System; class Program { static void Main(string[] args) { Console.WriteLine("Calling Test"); Test(); Console.WriteLine("Call to Test done"); } static void Test() { DisposeImplementation di = new DisposeImplementation(); } } internal class DisposeImplementation : IDisposable { ~DisposeImplementation() { Console.WriteLine("~ in DisposeImplementation instance called"); } public void Dispose() { Console.WriteLine("Dispose in DisposeImplementation instance called"); } } } The Dispose just never get's called, even if I put a wait loop after the Test(); invocation. So that quite sucks. I want to write a class that is straightforward and very easy to use, to make sure that every possible resource is cleaned up. I don't want to put that responsibilty to the user of my class. Possible solution: use using, or call Dispose myself(basicly the same). Can I force the user to use a using? Or can I force the dispose to be called? Calling GC.Collect(); after Test(); doesn't work either. Putting di to null doesn't invoke Dispose either. The Deconstructor DOES work, so the object get's deconstructed when it exits Test()

  • Maximize/Minimize is causing Close Button to be re-enabled after disabling it -- Why?

    - by Brainsick
    I have used P/Invoke to call GetSystemMenu and EnableMenuItem (win32api) to disable the close functionality. However, after minimizing or maximizing my Windows Forms application the button is re-enabled. Obviously minimizing or maximizing is causing the behavior, but how? I'm not sure where to look to prevent this behavior. Should I be preventing the maximize and minimize behavior or is there something particularly wrong with the way in which I P/Invoked the calls? Once the application (main form) has loaded, I call the static method from a button click. class PInvoke { // P/Invoke signatures [DllImport("user32.dll")] static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert); [DllImport("user32.dll")] static extern bool EnableMenuItem(IntPtr hMenu, uint uIDEnableItem, uint uEnable); // SysCommand (WM_SYSCOMMAND) constant internal const UInt32 SC_CLOSE = 0xF060; // Constants used with Add/Check/EnableMenuItem internal const UInt32 MF_BYCOMMAND = 0x00000000; internal const UInt32 MF_ENABLED = 0x00000000; internal const UInt32 MF_GRAYED = 0x00000001; internal const UInt32 MF_DISABLED = 0x00000002; /// <summary> /// Sets the state of the Close (X) button and the System Menu close functionality. /// </summary> /// <param name="window">Window or Form</param> /// <param name="bEnabled">Enabled state</param> public static void EnableCloseButton(IWin32Window window, bool bEnabled) { IntPtr hSystemMenu = GetSystemMenu(window.Handle, false); EnableMenuItem(hSystemMenu, SC_CLOSE, MF_BYCOMMAND | (bEnabled ?

  • Exposing a C++ API to C#

    - by Siyfion
    So what I have is a C++ API contained within a *.dll and I want to use a C# application to call methods within the API. So far I have created a C++ / CLR project that includes the native C++ API and managed to create a "bridge" class that looks a bit like the following: ManagedBridge.h namespace ManagedAPIWrapper { public ref class Bridge { public: int bridge_test(void); int bridge_test2(api_struct* temp); } } ManagedBridge.cpp int Bridge::bridge_test(void) { return test(); } int Bridge::bridge_test2(api_struct* temp) { return test2(temp); } I also have a C# application that has a reference to the C++/CLR "Bridge.dll" and then uses the methods contained within. I have a number of problems with this: I can't figure out how to call bridge_test2 within the C# program, as it has no knowledge of what a api_struct actually is. I know that I need to marshal the object somewhere, but do I do it in the C# program or the C++/CLR bridge? This seems like a very long-winded way of exposing all of the methods in the API, is there not an easier way that I'm missing out? (That doesn't use P/Invoke!)

  • Can you explain this generics behavior and if I have a workaround?

    - by insta
    Sample program below: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace GenericsTest { class Program { static void Main(string[] args) { IRetrievable<int, User> repo = new FakeRepository(); Console.WriteLine(repo.Retrieve(35)); } } class User { public int Id { get; set; } public string Name { get; set; } } class FakeRepository : BaseRepository<User>, ICreatable<User>, IDeletable<User>, IRetrievable<int, User> { // why do I have to implement this here, instead of letting the // TKey generics implementation in the baseclass handle it? //public User Retrieve(int input) //{ // throw new NotImplementedException(); //} } class BaseRepository<TPoco> where TPoco : class,new() { public virtual TPoco Create() { return new TPoco(); } public virtual bool Delete(TPoco item) { return true; } public virtual TPoco Retrieve<TKey>(TKey input) { return null; } } interface ICreatable<TPoco> { TPoco Create(); } interface IDeletable<TPoco> { bool Delete(TPoco item); } interface IRetrievable<TKey, TPoco> { TPoco Retrieve(TKey input); } } This sample program represents the interfaces my actual program uses, and demonstrates the problem I'm having (commented out in FakeRepository). I would like for this method call to be generically handled by the base class (which in my real example is able to handle 95% of the cases given to it), allowing for overrides in the child classes by specifying the type of TKey explicitly. It doesn't seem to matter what parameter constraints I use for the IRetrievable, I can never get the method call to fall through to the base class. Also, if anyone can see an alternate way to implement this kind of behavior and get the result I'm ultimately looking for, I would be very interested to see it. Thoughts?

  • Generics Java and Shadowing of type parameters

    - by rubixibuc
    This code seems to work fine class Rule<T> { public <T>Rule(T t) { } public <T> void Foo(T t) { } } Does the method type parameter shadow the class type parameter? Also when you create an object does it use the type parameter of the class? example Rule<String> r = new Rule<String>(); Does this normally apply to the type parameter of the class, in the situation where they do not conflict? I mean when only the class has a type parameter, not the constructor, or does this look for a type parameter in the constructor? If they do conflict how does this change? SEE DISCUSSION BELOW if I have a function call x = <Type Parameter>method(); // this is a syntax error even inside the function or class ; I must place a this before it, why is this, and does everything still hold true. Why don't I need to prefix anything for the constructor call. Shouldn't Oracle fix this.

  • Perl, Net::Traceroute::PurePerl return value

    - by John R
    This is a sub routine that I copied from CPAN. It works fine as it is when I run it from the command line. I have a similar function from Net::Traceroute that also works fine AND allows me to return the string with a SOAP call. The problem comes when I try to return the ~string(?) from the function below with a SOAP call. sub tr { use Net::Traceroute::PurePerl; my $t = new Net::Traceroute::PurePerl( backend => 'PurePerl', # this optional host => 'www.whatever.com', debug => 0, max_ttl => 30, query_timeout => 2, packetlen => 40, protocol => 'udp', # Or icmp ); $t->traceroute; $t->pretty_print; return $t; #print $t; } The output looks like a string except the last part of the string looks like this: 28 * * * 29 * * * 30 * * * Net::Traceroute::PurePerl=HASH(0x11fa6bf0) I don't know what is different about Net::Traceroute::PurePerl that won't allow me to return the value with SOAP since the Net::Traceroute version does allow me to return it with SOAP.

  • How can I use io.StringIO() with the csv module?

    - by Tim Pietzcker
    I tried to backport a Python 3 program to 2.7, and I'm stuck with a strange problem: >>> import io >>> import csv >>> output = io.StringIO() >>> output.write("Hello!") # Fail: io.StringIO expects Unicode Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unicode argument expected, got 'str' >>> output.write(u"Hello!") # This works as expected. 6L >>> writer = csv.writer(output) # Now let's try this with the csv module: >>> csvdata = [u"Hello", u"Goodbye"] # Look ma, all Unicode! (?) >>> writer.writerow(csvdata) # Sadly, no. Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unicode argument expected, got 'str' According to the docs, io.StringIO() returns an in-memory stream for Unicode text. It works correctly when I try and feed it a Unicode string manually. Why does it fail in conjunction with the csv module, even if all the strings being written are Unicode strings? Where does the str come from that causes the Exception? (I do know that I can use StringIO.StringIO() instead, but I'm wondering what's wrong with io.StringIO() in this scenario)

  • Change object on client side or on server side

    - by Polina Feterman
    I'm not sure what is the best practice. I have some big and complex objects (NOT flat). In that object I have many related objects - for example Invoice is the main class and one of it's properties is invoiceSupervisor - a big class by it's own called User. User can also be not flat and have department property - also an object called Department. For example I want create new Invoice. First way: I can present to client several fields to fill in. Some of them will be combos that I will need to fill with available values. For example available invoiceSupervisors. Then all the chosen values I can send to server and on server I can create new Invoice and assign all chosen values to that new Invoice. Then I will need to assign new supervisor I will pull the chosen User by id that user picked up on server from combobox. I might do some verification on the User such as does the user applicable to be invoice supervisor. Then I will assign the User object to invoiceSupervisor. Then after filling all properties I will save the new invoice. Second way: In the beginning I can call to server to get a new Invoice. Then on client I can fill all chosen values , for example I can call to server to get new User object and then fill it's id from combobox and assign the User as invoiceSupervisor. After filling the Invoice object on client I can send it to server and then the server will save the new invoice. Before saving server can run some validations as well. So what is the best approach - to make the object on client and send it to server or to collect all values from client and to make a new object on server using those values ?

  • Adding dynamic content with events in jquerymobile

    - by Christian Waidner
    Currently I'm stuck with a problem in jquerymobile: I'm adding items to a list dynamically and use enhanceWithin() in the end (so styling is correct). After this I like to add click-events for each list item but the problem is, that enhanceWithin runs asynchronous and so I always get the error message "cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'" When I delay the event-adding-code it works perfectly. Does anyone have an idea if there is a enhanceWithin.done event or anything else I can use? HTML: ... <div id="shoppinglist">Loading list...</div> ... Javascript: function updateList() { var result = ""; $.each(shoppinglistItems, function (index, item) { result += '<label><input type="checkbox" ' + item.checked + ' id="item_' + item.id + '">' + item.name + '</label>\n'; }); $('#shoppinglist').html(result).enhanceWithin(); // Change-Events an die Checkboxen knoten $('input[id*=item_]').unbind('change').bind('change', function (event) { var itemid = $(this).attr('id'); itemid = (itemid.split('_'))[1]; // Nur die Zahl extrahieren // Passendes Item aus der Liste der Items suchen und checken $.each(shoppinglistItems, function (index, item) { if (item.id == itemid) { item.checked = "checked"; item.timestamp = moment().format("YYYYMMDDHHmmss"); } }); updateList(); }); }
