• Google Document export via API

  - by micco

  After using Zend_GData to retrieve a document list feed, I can use the content URLs in the form: http://docs.google.com/document/edit?id=<docid>&hl=en but the source URLs in the form http://docs.google.com/feeds/download/documents/Export?docId=<docid>&exportFormat=html are returning 404 errors. That URL should return the content of the document in the requested format but it is returning 404. This problem is mentioned without resolution on a Google API forum. As indicated in that forum post, this problem only seems to affect new documents. My code works perfectly retrieving old documents, but new ones are 404. Has something changed in the way Google references new documents or in the way permissions are assigned? The code I'm using is essentially the same as the code on this page but this does not seem to be an issue specific to PHP/Zend_Gdata.

• Android App crashing on one device only

  - by Daniel1402

  I am working on a new game that works perfectly on my test devices, 7-inch tablets and smartphones. But it crashes on my Galaxy Tab2 10-inch tablet with an Out of memory error. It always crashes when I start to play a second game! I have spent a full week checking the codes and I cannot figure out what is wrong. When I play from the menu screen, everything works fine. When I want to replay a game level from the level screen, the game will crash on the second launch. The level screen is made of 3 fragments, each with 32 buttons (4kB in size). I tried to keep only one fragment in memory with viewPager.setOffscreenPageLimit(1); but it does not solve the problem. Could someone stir me in some direction as to where to look for the potential problem? Why is the 10-inch tablet the only one to crash? Thanks.

• MySqlConnection really not close

  - by stighy

  Hi guys, i've a huge problem. Take a look to this sample code private sub FUNCTION1() dim conn as new mysqlconnection(myconnstring) conn.open ---- do something FUNCTION2() ---- conn.close end sub private sub FUNCTION2() dim conn as new mysqlconnection(myconnstring) .... conn.open -- do something conn.close end sub Despite i close regulary all my connection, they remains "open" on the mysql server. I know this because i'm using MySQL Administration tool to check how many connection i open "line by line" of my source code. In fact i get a lot of time "user has exceeded the 'max_user_connections' resource (current value: 5)" My hoster permit ONLY 5 connection, but i think that if i write GOOD source code, this cannot be a problem. So my question is: why that "damn" connections remain open ?? Thank you in advance!

• Ruby does not run code correctly

  - by seefour

  I run this basic code in Ruby (on Windows): def hello () puts 'test' end hello and the Interpreter throws me this error: app.ru:1: syntax error, unexpected tIDENTIFIER, expecting $end hello puts 'test' It seems like Ruby is skipping lines? I've tried various encoding formats, other code and it still gives me an error similar to this. Why is it happening? EDIT The suggestions were to either use different editors or semi-colons to see if the lines were an issue. The version is also new - 1.9.3p327, so that shouldn't have been a problem. Parentheses aren't a problem either.

• Counter variable for class

  - by George

  I am having problem getting this piece of code to run. The class is Student which has a IdCounter, and it is where the problem seems to be. (at line 8) class Student: def __init__(self): # Each student get their own student ID idCounter = 0 self.gpa = 0 self.record = {} # Each time I create a new student, the idCounter increment idCounter += 1 self.name = 'Student {0}'.format(Student.idCounter) classRoster = [] # List of students for number in range(25): newStudent = Student() classRoster.append(newStudent) print(newStudent.name) I am trying to have this idCounter inside my Student class, so I can have it as part of the student's name (which is really an ID#, for example Student 12345. But I have been getting error. Traceback (most recent call last): File "/Users/yanwchan/Documents/test.py", line 13, in <module> newStudent = Student() File "/Users/yanwchan/Documents/test.py", line 8, in __init__ idCounter += 1 UnboundLocalError: local variable 'idCounter' referenced before assignment I tried to put the idCounter += 1 in before, after, all combination, but I am still getting the referenced before assignment error, can you explain to me what I am doing wrong?

• PyQt4.QtCore doesn't contain many of its classes and attributes

  - by toc777

  Hi everyone, I have built PyQt4 from source and everything went smoothly until I tried to use some of the classes and attributes located in QtCore. For some reason QtCore is missing a lot of functionality and data that should be there. For example from PyQt4.QtCore import QT_VERSION_STR is an import error. There were no errors or warnings given when building the packages and I have also tried with the PyQt packages from yum but I have the same problem. Has anyone else encountered this problem before? Thanks.

• IIS 6 Private Key certificate access

  - by gaizkile

  Hi, We have a Web asp.net application running in the framework 2.0 and hosted in an IIS 6 server, and the OS is windows server 2003. The web application is suing a client certificate to be authenticated by a web service. We have impersonalized the application pool with de user “Network Service”. The problem is when we have to access to the private key of the certificate that is stored in the machine key/my storage. The user Network Service cannot access the key. We have given privileges to the Network Service user using the winhttpcertcfg.exe tool, however the result is the same. When we impersonalize the application pool with the local administrator the result is successfully. Therefore we think that the problem is the privileges of the user. If someone could give us some information about, we would be gratefully. Thanks in advance

• ruby on rails sub directory inside in the 'Views' main directory

  - by Kum

  Hello, am a newbie in ruby on rails and am stuck with a simple problem of routing. I have my controller 'sub' and the 'Views' folder containing the add,edit,new erb files. In my routes file, i have 'map.resources :subs'. Until now, everything is fine. Problem: I moved the add,edit,new erb files into a subfolder called 'admin' inside the 'Views' main directory. I have no idea how to call those erb files from that 'admin' subdir. By default, it is looking for /app/views/subs/index.html.erb, and i want it to look in /app/views/subs/admin/index.html.erb Please can anyone tell me how to do this. Many many thanks

• How do I make TODO comments show up in the task list for C++ projects in Visual Studio 2010?

  - by Chris Simmons

  I'm trying to get my TODO comments to show up in the task list in Visual Studio 2010 for a C++ project, but they don't. I looked at this, but see no caveats other than the TODO comments need to be in the currently-open file. For example, creating a new Win32 console app places this: // TODO: reference additional headers your program requires here in a new file, stdafx.h. However, there's nothing in the task list. I have "Comments" chosen from the drop-down in the task list, but it's always empty. And it's not this problem; I can open the file and be looking at the TODO comment in the code editor and no task is shown. This is not a problem for C# projects as TODO comments show up as designed in those projects; this appears to be an issue specific to C++ projects. What else can I check?

• Long URLs (Bitly and TinyURL)

  - by Sixfoot Studio

  I'm sitting with a problem where I need to pass more than 2000 characters from my Flash application to an HTML page which reads the information and displays the correct options made in the Flash app the person came from. All's good but on the final stage, when the user needs to post their choices to a form, the character cannot be sent because the string is too long. Is there a way to use a service such as Bitly or TinyURL to send these long string and for them to be "deconstruction" on the other end when the form is sent? Otherwise, is there another solution to this problem? Many thanks!

• Host unavailable when user is logged off

  - by aksamit

  I am facing a problem that I discovered while I was implementing a small client/host application. The client side runs Windows 7 64-bit and machine never turns off but user is automatically logged off after 30 minutes of inactivity. When user is automatically logged off the host becomes unreachable, first I thought the problem was isolated to my application, but after som investigation I discoverd that resources and vnc server is also unavailable. The question might be a bit off limit for this forum but I can't find any reasonable explanation somewhere else. Does anyone know how I can keep user being logged off automatically but with the host still reachable on the network?

• Two part form in Rails

  - by samuel02

  I have some two nested resources, so that a Product can have many Bookings. On one page in a different controller I want to create a new booking and since it's a "general" booking I want a select menu to appear in a modal window where the user is able to pick one of the existing products and then go to the booking page. How can I do this? I have no problem setting up the modal and the "New booking" page is already there. What I need is a form that generates a list of existing products, picks the selected product id and then gets /products/:product_id/bookings/new . Any help appreciated! I realize my title does not describe my problem very good so better suggestions are highly welcome!

• looping thru a list of checkboxes and saving the values, not working properly

  - by Erez

  Hello all, I'm having a bit of a problem with this code. The program gives me a list of checkboxes but a user ID. then u user can change his selection and push the save button (id="btnSaveUserIntersts") and i am trying to save in the hidden textbox all the values of the checkboxes that was choosen.

• update dialog title for each click

  - by Scarface

  Hey guys I have a quick question, I have a dialog box that has multiple links with different attributes. Each time a link is clicked, the attribute src is printed inside of the dialog box so that each link has a unique output in the dialog. My problem is simply that only the first src title is in every box and I would like to change that as well with each click. I separated the line containing title to show the problem. If anyone has any ideas I would appreciate it. <a class="open" src="something" title="Click to play">link</a> <a class="open" src="something else" title="Click to play">link2</a> $('.open').click(function() { src=$(this).attr('src'); $('#show').html(''+src+''); $(\"#show\").dialog({hide: 'clip', width: 400,height: 150,position: 'center', show: 'clip',stack: true,title: ''+src+'', minHeight: 25, minWidth: 100, autoOpen: false,resizable:false}); $('#show').dialog('open'); })

• WPF: Can't get to original source from ExecutedRoutedEventArgs

  - by Ikhail

  I have a problem getting to the original source of a command using ExecutedRoutedEventArgs. I'm creating a simple splitbutton, in which a menu will appear below a dedicated button, as another button is pressed. When I click a menuitem in the appearing menu a command is fired. This command is registered on the splitbutton. And the idea is to get to the menuitem beeing clicked, by using the ExecutedRoutedEventsArgs. Ok, now the problem. If I choose to have the popup menu shown by default (IsOpen="True") and I click one of the menuitems I can get to the originalsource (thus the menuitem) from the ExecutedRoutedEventArgs - no problem. However, if I first click the button to show the menu and THEN click on a menuitem, the originalsource of the command will be the button instead of the MenuItem! Here's the controltemplate for the splitbutton: <ControlTemplate TargetType="{x:Type usc:SplitButton}"> <StackPanel Orientation="Horizontal"> <Button Name="mybutton"> <StackPanel> <Popup usc:SplitButton.IsPopup="True" IsOpen="True" Name="myPopup" PlacementTarget="{Binding ElementName=mybutton}" StaysOpen="False" Placement="Bottom"> <Border BorderBrush="Beige" BorderThickness="1"> <Menu Width="120"> <MenuItem Header="item1" Command="usc:SplitButton.MenuItemClickCommand" /> <MenuItem Header="item2" /> <MenuItem Header="item3" /> </Menu> </Border> </Popup> <TextBlock Text="MySplitbutton" /> </StackPanel> </Button> <Button Content="OK" Command="usc:SplitButton.ShowMenuCommand" /> </StackPanel> </ControlTemplate> The OK button fires a ShowMenuCommand on the SplitButton, which sets the IsOpen property on the Popup to True. Any ideas why the OK button (after having activated the menu) is the OriginalSource when a menuitem is clicked? Thanks.

• sports league database design

  - by John

  Hello, I'm developing a database to store statistics for a sports league. I'd like to show several tables: - league table that indicates the position of the team in the current and previous fixture - table that shows the position of a team in every fixture in the championship I have a matches table: Matches (IdMatch, IdTeam1, IdTeam2, GoalsTeam1, GoalsTeam2) Whith this table I can calculate the total points of every team based on the matches the team played. But every time I want to show the league table I have to calculate the points. Also I have a problem to calculate in which position classified a team in the last 10 fixtures cause I have to make 10 queries. To store the league table for every fixture in a database table is another approach, but every time I change a match already played I have to recalculate every fixture from there... Is there a better approach for this problem? Thanks

• Warning on standard headers after upgrading to NetBeans 6.8...

  - by paul

  After upgrading to NetBeans 6.8 on my Mac, some standard headers generate a warning. The warning is "There are unresolved includes inside <string>". <string> is just an example and <iostream> and <map> have the same warning. The project builds and runs fine; however, I would like to resolve these warnings. Has anybody else seen this problem? And is there any way to make that warning go away? I also didn't see this problem when I upgraded to 6.8 on Linux.

• Creative Technical Interview Questions for Developers

  - by John Shedletsky

  I do a good number of in-person technical interviews for new developers. I like to ask technical questions where I ask people to either code something up or develop an algorithm to solve a task. I feel my current repertoire is uninspired. In my opinion, the ideal interview question has these qualities: Multiple solutions, where some are obviously better than others, and some that involve subtle trade-offs (discussing tradeoffs is a good way to gauge someone's experience, in my opinion). Novelty - asking the "insert this element into a linked list" question is only good for weeding out people who never did their homework. Elegant - I like questions where the core problem isn't hidden in a lot of details. Everyone should be able to understand the problem, even if everyone can't solve it on the whiteboard. Elegant questions are difficult without involving undue amounts of "domain knowledge" or getting too narrow. Have you been on either side of an interview where someone (maybe you!) asked a particularly good programming or algorithms question?

• UI Design - design pattern for city/country drop down? (ASP.NET MVC)

  - by JK

  What is the best way to do a city/country dropdown pair in ASP.NET MVC? I see lots of places with country above city, but that's unnatural: in real life we write city/country. I've used city, then country, but the problem is that the user then has to go backwards after changing the country. The other problem is what do you do about cities/countries not in your list? If city/country are both drop downs, then the user cant type their own city if it is missing. But if you have a dropdown and a textbox, that makes it unwieldy (you end up with 4 controls to enter 2 pieces of data). Are there any examples websites where the city/country dropdown pair are done in a very useable and clear manner?

• Add Page Parameter in Zend Framework Doesn't Work

  - by deerawan

  Hello guys, I've been trying to figure this out these days. I got a problem when I want to add 'page' parameter in my URL for my pagination. This is my router -addRoute('budi',new Zend_Controller_Router_Route(':lang/budi',array('controller' = 'budi', 'action' = 'index', 'page' = 1), array('lang'=$s, 'page' = '\d+'))) -addRoute('budi1',new Zend_Controller_Router_Route(':lang/budi/page/:page',array('controller' = 'budi', 'action' = 'index', 'page' = 1), array('lang'=$s, 'page' = '\d+'))) Then I access my URL http://localhost/learningsystem/en/budi but when I hover on my pagination links, the page parameter doesn't appear. The URL is still http://localhost/learningsystem/en/budi but if I enter same URL with index in the end like this one http://localhost/learningsystem/en/budi/index or like this one http://localhost/learningsystem/en/budi/page/1 the page parameter appears perfectly when I click the page 2 link http://localhost/learningsystem/en/budi/index/page/2 Actually, I don't want include 'index' or 'page' at first in my URL. Anyway, I use default pagination.phtml template from Zend. Anyone please help me to solve this problem? Thank you very much

• Can’t dup NilClass - how to trace to offender

  - by fullware

  This exception occurs often and intermittently when in development mode, and appears to get triggered by model associations. Does There are lots of references found by google but none seem to help to trace the problem to an offending class. Does anyone have any insight into how to trace the occurrence of this exception to it's cause? I've seen the posts on adding "unloadable" but I'm not sure I buy it--unless there's a way to trace it somehow to its cause. I'm not in favor of indiscriminately adding such things to every class in hopes the problem might go away. Rails 2.3.5.
