• list of uids / names of System Preferences > Accounts

  - by neoneye

  How can I obtain an array with uid and names? I could iterate from 0 to 99999 and do a getpwnam(). However most machines have less than 5 accounts, so it's not optimal. I don't know what framework is responsible for this and thus I have no clue what to search for. Is there a more optimal solution that can traverse the accounts?

• Handover document for complete systems

  - by viraptor

  Hi, I need to create a handover document for a fairly large system consisting of all the stuff you'd expect from a telecom deployment: many servers, database clusters which copy some data between them in specific ways, tons of log files, both off-the-shelf and locally developed software, scripts, network configurations, local know-how, etc. It's really got as many sysadmin-typical elements, as development ones. The target of this document are in the first place sysadmins who take over the day-to-day operation tasks and some problem resolving, and in the second place people who want to learn about the system in general. Is there some place I can learn about how to write something like that? It could just as easily be a 10 page "what's where", as a 500 pages book about "all things telephony". Maybe it should be more than one document really. Please link some useful resources / books I could use for this task. PS: this is intended to be internal only, customer interactions etc. are out of scope here

• Value was either too large or too small for an Int16 error

  - by Barlow Tucker

  I am working on fixing a bug in VB that is giving this error. I am new to VB, so there is some syntax that I am not fully understanding. The code that is throwing the error says: .Row(itemIndex).Item("parentIndex") = CLng(oID) + 1000000 I understand that adding 1000000 is too much for an int16. I can't change that value (not right now anyway). What I don't understand, and can't seem to find, is what .Row is referring too. Any ideas?

• Proper error handling in a custom Zend_Autoloader?

  - by Pekka

  I'm building a custom autoloader based on Zend Framework's autoloading (related question here). The basic approach, taken from that question, is class My_Autoloader implements Zend_Loader_Autoloader_Interface { public function autoload($class) { // add your logic to find the required classes in here } } and then binding the new autoloader class to a class prefix. Now what I'm unsure about is how to handle errors inside the autoload method (for example, "class file not found") in a proper, ZF compliant way. I'm new to the framework, its conventions and style. Do I quietly return false and let the class creation process crash? Do I output an error or log message somehow (which would be nice to pinpoint the problem) and return false? If so, what is the Zend way of doing that? Do I trigger an error? Do I throw an exception? If so, what kind?

I don't understand why they don't destroy on their own as usually they do.

• Getting meaningful error messages from fstream's in C++

  - by Hassan Syed

  What is the best way to get meaningful file access error messages, in a portable way from std::fstreams ? The primitiveness of badbits and failbits is getting to be bit annoying. I have written my own exception hierarchies against win32 and POSIX before, and that was far more flexible than the way the STL does it. I am getting "basic::ios_clear" as an error message from the what method of a downcasted catch (std::exception) of a fstream which has exceptions enabled. This doesn't mean much to me, although I do know what the problem is I'd like my program to be a tad more informative so that when I start deployment a few months later my life will be easier. Is there anything in Boost to extract meaningful messages out of the ofstream's implementation cross platform and cross STL implementation ?

• Inheriting System.Windows.Controls.Panel

  - by modosansreves

  I use the Panel to provide custom layout of UIElements. For this, I override MeasureOverride and ArrangeOverride. In ArrangeOverride proper locations are given to Children. In my application, there is a bunch of rather heavy (by number of visuals) children inside the panel, but only 2 of them are located inside the visible region at a time. Working with my application I feel like all the visuals are drown. I need to introduce a kind of 'virtualization' and make the children render (or take CPU cycles) selectively. How do I?

• JQuery JEditable stay in edit mode on error

  - by Justin

  I'm successfully using jeditable to submit via a function using jQuery.ajax and the async : false option , but am having an issue aborting if an error is returned. How can I get the edit box to stay activated and / or revert back to the original value if there are errors? I'm returning http status codes. so something like async : false .ajax submit here... if (xhr.status == 200) { return value; else { alert ('returned error'); // keep edit box activated but available for another try, or revert back to original value } I tried not returning a value from the function, which keeps the edit box activated and ready for another submit, but then the ESC key doesn't work anymore and if I click outside the edit area, the edit box stays. Thanks in advance!

• MSVC++ 6.0: Fatal error C1509 "Too many exception handler states in function"

  - by sep332

  I'm working on a project that uses a lot of generated files for a GUI. After some recent updates, I get this error. If I remove some controls (the new ones or some old ones, doesn't seem to matter which), the error goes away. I've temporarily worked around the problem, but I'd like a more permanent solution. I've seen mentioned on the web that there's a fix for this in VS.Net 2003, but I can't find anything for 6.0. Does anyone know of a hotfix or service pack that fixes this?

• Gridview with row being edited causing error when form submitted

  - by Chris Phelps

  Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

• Incorrect error

  - by jspooner

  If you assign an invalid date (like December 39th) to a datetime column ActiveRecord returns a "can't be blank" error when is should probably return an error like "Not a valid date" My question. Is this expected rails behavior, a bug or, something that I could patch? class ExerciseLog < ActiveRecord::Base validates_presence_of :scheduled_datetime end Fire up the console. e = Log.new # lets set a date for Dec 39th which obviously doesn't exist e.scheduled_datetime = "2010-12-39" e.save => false # this is the confusing message since our form did post a valid date e.errors.on(:scheduled_datetime) => "can't be blank" e.scheduled_datetime = "2010-12-30" e.save => true I discovered this issue when I accidentally transposed the month and day values. btw This is in Rails 2.3.5

• Windows Installer (C#) error code 2869

  - by KP

  I have a project, in VS 2005, which has a console application and a setup project associated to install the application. I also have an installer class in the console application that the setup project will use to do some validation before installation. Those tasks are checking the database connection string and checking some directory locations to make sure they exist prior to installation. I am getting an error code of 2869 when I try to install the application. All the code is written in C#. I have googled for this error code on Windows XP, but only found articles that deal with Vista and Windows 7. Any ideas what might be happening? Is there a workaround?
