• Why do I randomly get a "error to use section registered as allowDefinition='MachineToApplication'"

  - by Jedidja

  I have seen a few questions on SO about a similar error when deploying a website, but I seem to randomly get this error when building an ASP.NET MVC website in Visual Studio. Performing a clean usually fixes it, but is there any way to avoid this completely? It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. d:...\obj\debug\package\packagetmp\web.config Note that it is complaining about the root web.config, not the one from the Views subdirectory.

• How to calculate a RTOS task's time

  - by Adnan

  Hello all, I have written a code in c for Arm7 using RTOS. There are multiple tasks who's priority is set to same level. So the tasks executes on round-robin base. There is an exception that one task (Default) has set to lower priority then the other task in rtos. So that if no task is running, the default or lower priority task runs. Now i want to calculate the exact total timing (time duration) for that default task runs. Can any one give some idea what to do .... and how to do in code.. Regards Dani

• How to validate HTTP request headers before receiving request body using WCF

  - by anelson

  I'm implementing a REST service using WCF which will be used to upload very large files. The HTTP headers in this request will communicate information which will be validated prior to allowing the upload to proceed (things like permissions, available disk space, etc). It's possible this validation will fail resulting in an error response. I'd like to do this validation prior to the client sending the body of the request, so it has a chance to detect failure before uploading potentially gigabytes of data. RESTful web services use the HTTP 1.1 Expect: 100-continue in the request to implement this. For example Amazon S3's REST API can validate your key and ACLs in response to an object PUT operation, returning 100 Continue if all is well, indicating you may proceed to send your data. I've rummaged around the WCF documentation and I just can't see a way to accomplish this without doing some pretty low-level hooking into the HTTP request processing pipeline. How would you suggest I solve this problem?

• Exceptions & Interrupts

  - by Betamoo

  When I was searching for a distinction between Exceptions and Interrupts, I found this question Interrupts and exceptions on SO... Some answers there were not suitable (at least for assembly level): "Exception are software-version of an interrupt" But there exist software interrupts!! "Interrupts are asynchronous but exceptions are synchronous" Is that right? "Interrupts occur regularly" "Interrupts are hardware implemented trap, exceptions are software implemented" Same as above! I need to find if some of these answers were right , also I would be grateful if anyone could provide a better answer... Thanks!

• How to serialize a collection of base type and see the concrete types in easy to read XML

  - by Jason Coyne

  I have a List which is populated with objects of various concrete types which subclass BaseType I am using the WCF DataContractSerializer <Children> <BaseType xmlns:d3p1="http://schemas.datacontract.org/2004/07/Tasks" i:type="d3p1:ConcreteTypeA"></BaseType> <BaseType xmlns:d3p1="http://schemas.datacontract.org/2004/07/Tasks" i:type="d3p1:ConcreteTypeB"></BaseType> </Children> Is there any way to get this to generate <Children> <ConcreteTypeA/> <ConcreteTypeB/> </Children> ? The real goal is to let users generate some XML to load into memory, and the users are of a skill level that asking them for the original XML is not going to be successful.

• Google Maps - user to pinpoint a location

  - by JohnB

  Hi, Is it possible to allow users of my website to mark places on a map I display using Google Maps API? I need to then save that location coordinates to a db. I've been looking through the google maps API, I found that I can use the web service to do searches like this: http://maps.google.com/maps/geo?q=Maine,+United+States&output=json&oe=utf8\&sensor=false&key=my_key But I am not sure it's working on a house number level (which I need it to) and I'm not sure how to display a 'did you mean?' to the user when he misspells the address.. Anyone have an idea? Thanks,

• ASP.net displaying data from SQL data source

  - by c11ada

  hey all, im using linq2SQL to grab information from my SQL database, i have a gridview which shows all the top level information, in this case a list of groups (i.e admin, users and so on) when a user clicks say the admin group, i want to be able to show each member in that group, i have the following code which grabs the information from the database, DataClassesDataContext dc = new DataClassesDataContext(); GridViewRow row = GridView1.SelectedRow; var query1 = from p in dc.Users where p.groups.GroupID == Int32.Parse(row.Cells[1].Text) select new { p.Name, p.Address, p.Contact Number, p.Bio, }; i no i can use gridview again to display the results of the query, but this doesnt really look nice as it shows too much information at one, how would i go about having some sort of display which will show just one user at a time giving me the chance to click next and back ? thanks

• Gradle java.util.logging.Logger output in unit tests

  - by Misha Koshelev

  Dear All: Sorry this is probably a very simple question. I am using gradle http://www.gradle.org/ for my development environment. It works quite well! I have written a simple unit test that uses HtmlUnit and my own package. For my own package, I use java.util.Logger. HtmlUnit seems to use commons logging: http://htmlunit.sourceforge.net/logging.html I would like to see console output of my logging messages from java.util.Logger However, it seems that even messages at the info level are not displayed in my Unit Test Results GUI (System.err link), although the HtmlUnit messages are all displayed. Please let me know if you have suggestions. Thank you! Misha

• SQL 05 full-text query fails "Specified module could not be found."

  - by Dan Bailiff

  I'm running SQL 2005 on Windows XP. I have a database table that has full text searching enabled. I was able to build and even re-build the index. However, when I try to query it like this: Select * from fulltext_english WHERE CONTAINS(page_data, 'causes') I get this error: Msg 7619, Level 16, State 1, Line 1 The execution of a full-text query failed. "The specified module could not be found." Did I miss something on the install? Is this a dll issue? I've googled and binged for days and can't find anything similar to this message. Thanks!

• cakephp VS codeigniter VS zend framework

  - by i need help

  Very possibly very related: What PHP framework would you choose for a new application and why? Zend or CakePHP? Which one is better? Some people say CakePHP is better for php 4, what do you think? In my case, I would like the following: Lesser code to write, have really strong library and plugin base. Always have new library etc added in from contributor, eg: google map and etc... Ability to use together with the templating system like smarty. Have ACL that can control all the permission level issue. Load class when needed, unload when not needed. Load class once and use globally. Can run in windows environment (I am using xampp to run my php in windows.) After the site done, I will upload all codes into windows 2008 server (using php 5)

• Using OpenGL drawing operations in an object-oriented setting?

  - by Lion Kabob

  I've been plowing through basic shaders and whatnot for an application I'm writing, and I've been having trouble figuring out a high-level organization for the drawing calls. I'm thinking of having a singleton class which implements a number of basic drawing operations, taking data from "user" classes and passing that to the appropriate opengl calls. I'm wondering how people do this when writing their own applications, as the internet is chock full of basic "Your first shader" tutorials, but very little on suggested organization of drawing code. My particular environment is targeted at iPad/OpenGL ES 2.0, but I think the question stands for most environments.

• Asp.Net MVC style routing in Django

  - by Andrew Hanson

  I've been programming in Asp.Net MVC for quite some time now and to expand a little bit beyond the .Net world I've recently began learning Python and Django. I am enjoying Django but one thing I am missing from Asp.Net MVC is the automatic routing from my urls to my controller actions. In Asp.Net MVC I can build much of my application using this single default route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); In Django I've found myself adding an entry to urls.py for each view that I want to expose which leads to a lot more url patterns than I've become used to in Asp.Net MVC. Is there a way to create a single url pattern in Django that will handle "[Application]/view/[params]" in a way similar to Asp.Net MVC? Perhaps at the main web site level?

• How to check if an apply-template filled variable is a string or (possibly) empty node in XSLT?

  - by calavera.info

  I need a test which would evaluate to true in two cases: There is a string inside which contains any non white space characters There is any node (which can be possibly empty) on a variable that is filled with apply-template call result. I tried test="normalize-space($var)" but this doesn't cover the empty tag possibility. I also tried simply this: test="$var" but this evaluate to true even for white space only strings. By the way "$var/*" produces an error "Expression ...something I don't remember... node-set" which is I think because of apply-template variable instantiation. Is there any (which means even multi level decision) solution for this? EDIT: I forgot to say that it's for XSLT 1.0 and preferably without any exslt extensions or similar.

• How do I serve nested static content on Heroku?

  - by Matthew Murdoch

  I have a rails application with static content in the public directory (e.g. public/index.html) and additional static content in nested subdirectories (e.g. public/one/two/index.html). All the static content is served correctly if I run it locally via script/server but when I upload it to Heroku the top-level page loads correctly but the nested content returns a 404. I've found a number of resources (for example this question) which discuss static content in rails but they all seem to assume a fairly simple structure with a single directory containing all the files. Is there any way I can fix this?

• django authentication .htaccess static

  - by Uszy Wieloryba

  In my app users can upload files for other users. To make the uploaded files accesible only for the addresse I need some kind of static files authentication system. My idea, is to create the apache hosted directory for each user and to limit access to this derectory using .htaccess. This means that each time new django user is created, I need to create a directory and the appropriate .htaccess file in it. I know I should do it using post_save signals on User model but I don't know how to create the .htaccess in the user's directory from python level. Can you help me with that? Or perhaps you have better solution to my problem?

  - by swati

  ello Everyone, I am new to using apache logger .

• How to set timeout with python-mechanize?

  - by Michal Cihar

  I'm using python-mechanize to scrape some web sites, which sometime simply don't respond to requests and these requests stay open too long, so I need to limit timeout for these requests. While using urlopen method, the timeout can be set using timeout parameter, but I have not found easy way for doing it with high level API such as submit or click methods. Ideally the timeout would be set just once for whole browser class and all calls would honor that. It would be probably possible to customize this by passing custom request_class to every click and submit call, but this would just pollute the code, so I'm looking for nicer solution for setting timeout for mechanize's browser class (and no, I don't want to change default socket timeout using socket.setdefaulttimeout).

• linq hierarchy problem

• Applet in different directory than .html page

  - by Jorge Matos

  Hello all, I'm trying to use a different directory to contain the applets and other directory with .html pages. Both are in the same level, that is, none is a sub-directory of the other. For that I was trying to use the parameter codebase, however, no matter what I put in codebase value (relative, absolute path) I always get a class not found error. I googled and found some people with the same problem, but no answers:( Does anybody knows how to accomplish this? I'm using JRE 1.6_20. Cheers, Jorge

• Performance Tricks for C# Logging

  - by Charles

  I am looking into C# logging and I do not want my log messages to spend any time processing if the message is below the logging threshold. The best I can see log4net does is a threshold check AFTER evaluating the log parameters. Example: _logger.Debug( "My complicated log message " + thisFunctionTakesALongTime() + " will take a long time" ) Even if the threshold is above Debug, thisFunctionTakesALongTime will still be evaluated. In log4net you are supposed to use _logger.isDebugEnabled so you end up with if( _logger.isDebugEnabled ) _logger.Debug( "Much faster" ) I want to know if there is a better solution for .net logging that does not involve a check each time I want to log. In C++ I am allowed to do LOG_DEBUG( "My complicated log message " + thisFunctionTakesALongTime() + " will take no time" ) since my LOG_DEBUG macro does the log level check itself. This frees me to have a 1 line log message throughout my app which I greatly prefer. Anyone know of a way to replicate this behavior in C#?

• How do I actually use Authorization Services?

  - by abrahamvegh

  I've been searching and experimenting for nearly four hours now, so I'm gonna just ask straight up: How can I correctly use the Authorization Services API to show the user a system-level authorization window, the same one you see when you click a lock icon in System Preferences? From what I can tell, there is no way to do it using Cocoa if you want to do it programmatically, and if your goal is to call an executable that normally needs to be called via sudo (in my case, /usr/bin/pmset) you're up a creek without a paddle. I challenge you, I implore you: Please, enlighten me. Thank you. :)

• Developer workload management software: recommendations?

  - by PaddyC

  In my place, we use two issue tracking tools, one for production bugs, and another for issues on projects in development. These tools are good for managers. However, at an individual level, other work can also arrive through desk visits, email, or the phone, and those allocating the work aren't always interested in issue tracking systems. I've recently rolled off an 18-month project where I got into a cycle of overtime, and I found that I didn't always have good visibility of all work assigned to me. As a result, I was always very busy, and felt constantly laden down with work, but didn't have the clear data to show my manager (or, ironically, the time to stop and gather the information!). A handwritten list, updated at the end of each day, is a good start, but can anyone recommend better tools to help me get a clear view of my own workload? Ideally, I'm thinking of software tools for developers, which could incorporate estimates, but all suggestions welcome. Thanks, Paddy

• Defend zero-based arrays

  - by DrJokepu

  A question asked here recently reminded me of a debate I had not long ago with a fellow programmer. Basically he argued that zero-based arrays should be replaced by one-based arrays since arrays being zero based is an implementation detail that originates from the way arrays and pointers and computer hardware work, but these sort of stuff should not be reflected in higher level languages. Now I am not really good at debating so I couldn't really offer any good reasons to stick with zero-based arrays other than they sort of feel like more appropriate. I am really interested in the opinions of other developers, so I sort of challenge you to come up with reasons to stick with zero-based arrays!
