• Using WebMatrix and Visial Studio 2010 on a Razor project

  - by Terrence Koehn

  I am having problems using both WebMatrix and VS on a Razor project. I have downloaded and installed all updates from the official ASP.net web site. After getting the project to compile in VS I get the following error: "The type of page you have requested is not served because it has been explicitly forbidden. The extension '.cshtml' may be incorrect." Now when I open the project in WebMatrix I receive the same error. I can open/run other projects in WebMatrix without errors so apparently VS changed some configuration in my project? Fortunately I have found a work around but the problem is still not solved. 1) Create a new empty folder for site. 2) Copy contents of folder from failing site. 3) In WebMatrix use option "Site From Folder". Once I have the site up and running with the above steps I can delete the original folder, then rename the new folder (which is now working) to the orig name and the site will stop working again. There is some setting on my system tied to the original folder name that is stopping cshtml files from being served. What/Where is that setting? Thanks, Terrence Koehn

• questions about using svn

  - by ajsie

  i have set up a svn repository in a remote ubuntu server using webdav (http://ip/svn). but i have some questions: should i create one svn repository for each project folder? so i should use "svnadmin create" 5 times for 5 projects? or should i import them to seperate folders in the svn repository? should i after i have created a svn repo, import one project folder into it with "svn import" and then DELETE my original local folder thus only having it in the svn repo in the remote ubuntu server? is this safe or should i still have a local copy for some reason (cause i wont work in that one)? i use netbeans to check out projects from svn repo, then i edit the files and commit the changes. but how should i do to update the live web server content (in /var/www)? should i in my ubuntu server use "svn checkout" and check it out to /var/www or should i use netbeans to check out to a local folder and then upload the files to /var/www with ftp or webdav (and which one of them should i use)? so i got a svn repo and lets say 4 programmers are working with it, checking out and commiting. how do i check what is happening in the repo, which one made which changes, and all the changes from day 1 to day 213? does netbeans/eclipse letting me see this kind of information or do i download another application for it? i should have one svn user for each programmer in the ubuntu server? is this accomplished by using "htpasswd" 4 times for 4 programmers? how do i couple all these users to same group so that i could modify file access specific for the svn group and all its members?

• Use AJAX to reload captcha

  - by arik-so

  Hello! This question may have been asked already - but unfortunately, I could not find any satisfactory answers. I will just ask it for my concrete case and ask the admins not to delete the question for at least a few days so I can try it out... I have a page. It uses a captcha. Like so: <?php session_start(); // the captcha saves the md5 into the session ?> <img src="captcha.php" onclick="this.src = this.src" /> That was my first code. It did not work, because the browser condsidered it useless to reload an image if the source is the same. My current solution is to pass a get parameter: onclick="this.src = 'captcha.php?randomNumber='+ranNum" The JavaScript variable var ranNum is generated randomly every time the onclick event fires. It works fine, still, I don't like the possibility, if the - though improbable - case of two numbers being the same twice in a row. Although the random number varies between -50,000 and 50,000 - I still do not like it. And I don't think the method is right. I would like to know the 'righter' method, by means of AJAX. I know it's possible. I hope you know how it's possible ^^ In that case, please show me. Thanks in advance! By the way - if I spell cap(t)cha differently, never mind, the reference to the PHP file is right in my code: I use randomImage.php

• server/ client server connection

  - by user312054

  I have a server side program that creates a listening server side socket. The problem occurring is that it seems as if the client side sends a connect request it gets rejected if the server side socket is listening but connects if the server side program is not running. I can see the server side program getting the client request when debugging. It seems as if the client cannot connect to a listening socket. Any suggestions on a resolution? The server side accept code snippet is this. void CSocketListen::OnAccept(int nErrorCode) { CSocket::OnAccept(nErrorCode); CSocketServer* SocketPtr = new CSocketServer(); if (Accept(*SocketPtr)) { // add to list of client sockets connected } else { delete SocketPtr; } The client side code connect is like this. SOCKET cellModem; sockaddr_in handHeld; handHeld.sin_family = AF_INET; //Address family handHeld.sin_addr.s_addr = inet_addr("127.0.0.1"); handHeld.sin_port = htons((u_short)1113); //port to use cellModem=socket(AF_INET,SOCK_STREAM,0); if(cellModem == INVALID_SOCKET) { // log socket failure return false; } else { // log socket success } if (connect(cellModem,(const struct sockaddr*)&handHeld, sizeof(handHeld)) != 0 ) { // log socket connection success } else { // log socket connection failure closesocket(cellModem); }

• Handle row deletion in UITableViewController

  - by Kamchatka

  Hello, I hava a UINavigationController. The first level is a UITableViewController, the second level just shows details on one of the items of the table view. In this detail view, I can delete the item. It deletes the underlying managed object. When I pop back to the view, I have a crash. I understand why, it's because I didn't update the cached array that contains the data. I looked at several tutorials and I don't exactly understand how am I supposed to handle deletion. Maybe I don't understand exactly where I should fetch the objects in the model. Should I do a query for every cellForRowAtIndexPath and take the item in the result at position indexPath.row? It doesn't look efficient. Should I check for changes somewhere and recache the whole query in an array. I would think CoreData would provide something more natural but I couldn't find it so far. Thanks in advance.

• Cucumber-rails on jruby installs gem into my apps root directory with bundler

  - by brad

  Just installed cucumber 0.7.2 and cucumber-rails 0.3.1 with jruby-1.4.0 on OSX. When I run a bundle install, it places a cucumber-rails directory in my main app with all of the gem code/dependencies. First off, this is definitely not what I want and I'm not sure why this happens for cucumber-rails only. Second, if I delete this folder and just manually install cucumber-rails, when I run script/generate feature blah I get /Users/bradrobertson/.rvm/rubies/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:344:in `refresh!': source index not created from disk (RuntimeError) from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/vendor_gem_source_index.rb:34:in `refresh!' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/vendor_gem_source_index.rb:29:in `initialize' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/gem_dependency.rb:21:in `new' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/rails/gem_dependency.rb:21:in `add_frozen_gem_path' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:298:in `add_gem_load_paths' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:132:in `process' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from /Users/bradrobertson/Repos/app/source/trunk/config/environment.rb:13 from /Users/bradrobertson/Repos/app/source/trunk/config/environment.rb:1:in `require' from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/commands/generate.rb:1 from /Users/bradrobertson/.rvm/gems/jruby-1.4.0/gems/rails-2.3.5/lib/commands/generate.rb:3:in `require' from script/generate:3 Similarly running rake cucumber I get rake aborted! source index not created from disk So something obviously doesn't work. If I add that cucumber-rails directory back in, then my rake cucumber actually runs. Can someone tell me why it would need to install the gem right in my rails app? I've never seen this before. setup jruby-1.4.0 cucumber-0.7.2 cucumber-rails 0.3.1 bundler 0.9.23 webrat 0.7.1

• How to exit grid with ctrl-TAB when grid is on a tabpage (onkeydown works when grid not on tabpage)

  - by Charles Hankey

  winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid : Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs) If e.KeyCode = Windows.Forms.Keys.Tab andalso e.control = True then SetFocusToNextControl(True) End if Mybase.OnKeyDown(e) End Sub This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well. FWIW I tried a different combination like ctrl-E and got pretty much the same result with focus disappearing from the grid but not going anywhere I could detect. The sub still saw the e.control as controlkey. Oddly, ctrl-X, ctrl-A etc all work in the grid and a ctrl-Delete combo I put in the subclass for deleting a row works fine. Once again - grid directly on form and it all works. I'm definitely over my head on this one. Guidance much appreciated. vb or c# fine. TIA

• Meaning of Execute_priv on mysql.db table

  - by Ben Reisner

  I created user 'restriceduser' on my mysql server that is 'locked down'. The mysql.user table has a N for all priveledges for that account. The mysql.db table has Y for only Select, Insert, Update, Delete, Create, Drop; all other privileges are N for that account. I tried to create a stored procedure and then grant him access to run only that procedure, no others, but it does not work. The user receives: Error: execute command denied to user 'restricteduser'@'%' for routine 'mydb.functionname' The stored procedure: CREATE DEFINER = 'restriceduser'@'%' FUNCTION `functionname`(sIn MEDIUMTEXT, sformat MEDIUMTEXT) RETURNS int(11) NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER COMMENT '' BEGIN .... END; The grant statement I tried: GRANT EXECUTE ON PROCEDURE mydb.functionname TO 'restricteduser'@'%'; I was able to work around by modifying his mysql.db entry with update mysql.db set execute_priv='Y' where user='restricteduser' This seems to be more then I want, because it opens up permissions for him to run any stored procedure in that database, while I only wanted him to have permissions to run the designated function. Does anyone see where my issue may lie?

• Using Facebook Login to create a user?

  - by andbeyond

  I've read this SO post which led me to this FB policy page, which seemed to include some pertinent information, but I'd like more of a community response, maybe some experienced FB API people who know the limits. My question is if I can use Facebook's Login api to, essentially, create a new user on my website. I really would just like to allow users to easily "transfer" some data from FB in order to more easily create a new account on my site. I realize, first and foremost, that I would obviously announce to the user that by click "submit" in the form, that they are creating a separate account on my site. Pertinent blocks on the policy page state: You may cache data you receive through use of the Facebook API in order to improve your application’s user experience, but you should try to keep the data up to date. This permission does not give you any rights to such data. Which doesn't look good for me, but also this: If you stop using Platform or we disable your application, you must delete all data you have received through use of the Facebook API unless: (a) it is basic account information; or (b) you have received explicit consent from the user to retain their data. Which, in my case, I would be satisfying part B. I would be asking the user's permission to retain the data, as I am simply using Facebook as a conveience to the user when creating an account. I also realize that Facebook has a registration API, but this would require a Facebook styled login form, along with my own sites login form, and I'd rather one interface, as this makes it easier for me on the front and back end. Any thoughts?

• Extracting a .app from a zip file in Python, using ZipFile

  - by Yakattak

  I'm trying to extract new revisions of Chromium.app from their snapshots, and I can download the file fine, but when it comes to extracting it, ZipFile either extracts the chrome-mac folder within as a file, says that directories don't exist, etc. I am very new to python, so these errors make little sense to me. Here is what I have so far. import urllib2 response = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/LATEST') latestRev = response.read() print latestRev # we have the revision, now we need to download the zip and extract it latestZip = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev)), '~/Desktop/ChromiumUpdate/%i-update' % (int(latestRev))) #declare some vars that hold paths n shit workingDir = '/Users/slehan/Desktop/ChromiumUpdate/' chromiumZipPath = '%s%i-update.zip' % (workingDir, (int(latestRev))) chromiumAppPath = 'chrome-mac/' #the path of the chromium executable within the zip file chromiumAppExtracted = '%s/Chromium.app' % (workingDir) # path of the extracted executable output = open(chromiumZipPath, 'w') #delete any current file there output.write(latestZip.read()) output.close() # we have the .zip now we need to extract the Chromium.app file, it's in ziproot/chrome-mac/Chromium.app import zipfile, os zippedFile = open(chromiumZipPath) zippedChromium = zipfile.ZipFile(zippedFile, 'r') zippedChromium.extract(chromiumAppPath, workingDir) #print zippedChromium.namelist() zippedChromium.close() #zippedChromium.close() Any ideas?

• Message queue proxy in Python + Twisted

  - by gasper_k

  Hi, I want to implement a lightweight Message Queue proxy. It's job is to receive messages from a web application (PHP) and send them to the Message Queue server asynchronously. The reason for this proxy is that the MQ isn't always avaliable and is sometimes lagging, or even down, but I want to make sure the messages are delivered, and the web application returns immediately. So, PHP would send the message to the MQ proxy running on the same host. That proxy would save the messages to SQLite for persistence, in case of crashes. At the same time it would send the messages from SQLite to the MQ in batches when the connection is available, and delete them from SQLite. Now, the way I understand, there are these components in this service: message listener (listens to the messages from PHP and writes them to a Incoming Queue) DB flusher (reads messages from the Incoming Queue and saves them to a database; due to SQLite single-threadedness) MQ connection handler (keeps the connection to the MQ server online by reconnecting) message sender (collects messages from SQlite db and sends them to the MQ server, then removes them from db) I was thinking of using Twisted for #1 (TCPServer), but I'm having problem with integrating it with other points, which aren't event-driven. Intuition tells me that each of these points should be running in a separate thread, because all are IO-bound and independent of each other, but I could easily put them in a single thread. Even though, I couldn't find any good and clear (to me) examples on how to implement this worker thread aside of Twisted's main loop. The example I've started with is the chatserver.py, which uses service.Application and internet.TCPServer objects. If I start my own thread prior to creating TCPServer service, it runs a few times, but the it stops and never runs again. I'm not sure, why this is happening, but it's probably because I don't use threads with Twisted correctly. Any suggestions on how to implement a separate worker thread and keep Twisted? Do you have any alternative architectures in mind?

• ACL architechture for a Software As a service in Sprgin 3.0

  - by geoaxis

  I am making a software as a service using Spring 3.0 (Spring MVC, Spring Security, Spring Roo, Hibernate) I have to come up with a flexible access control list mechanism.I have three different kinds of users System (who can do any thing to the system, includes admin and internal daemons) Operations (who can add and delete users, organizations, and do maintenance work on behalf of users and organizations) End Users (they belong to one or more organization, for each organization, the user can have one or more roles, like being organization admin, or organization read-only member) (role like orgadmin can also add users for that organization) Now my question is, how should i model the entity of User? If I just take the End User, it can belong to one or more organizations, so each user can contain a set of references to its organizations. But how do we model the users role for each organization, So for example User UX belongs to organizations og1, og2 and og3, and for og1 he is both orgadmin, and org-read-only-user, where as for og2 he is only orgadmin and for og3 he is only org-read-only-user I have the possibility of making each user belong to one organization alone, but that's making the system bounded and I don't like that idea (although i would still satisfy the requirement) If you have a better extensible ACL architecture, please suggest it. Since its a software as a service, one would expect that alot of different organizations would be part if the same system. I had one concern that it is not a good idea to keep og1 and og2 data on the same DB (if og1 decides to spawn a 100 reports on the system, og2 should not suffer) But that is some thing advanced for now and is not directly related to ACL but to the physical distribution of data and setup of services based on those ACLs This is a community Wiki question, please correct any thing which you wish to do so. Thanks

• File Storage for Web Applications: Filesystem vs DB vs NoSQL engines

  - by El Yobo

  I have a web application that stores a lot of user generated files. Currently these are all stored on the server filesystem, which has several downsides for me. When we move "folders" (as defined by our application) we also have to move the files on disk (although this is more due to strange design decisions on the part of the original developers than a requirement of storing things on the filesystem). It's hard to write tests for file system actions; I have a mock filesystem class that logs actions like move, delete etc, without performing them, which more or less does the job, but I don't have 100% confidence in the tests. I will be adding some other jobs which need to access the files from other service to perform additional tasks (e.g. indexing in Solr, generating thumbnails, movie format conversion), so I need to get at the files remotely. Doing this over network shares seems dodgy... Dealing with permissions on the filesystem as sometimes given us problems in the past, although now that we've moved to a pure Linux environment this should be less of an issue. What are the downsides of storing files as BLOBs in MySQL? I guess that it would massively increase the database size and reduce the effectiveness of caches, but are there other problems? Do the same problems exist with NoSQL systems like Cassandra? Does anyone have any other suggestions that might be appropriate?

• Best way to handle Many-to-Many relationships in PHP MySQL

  - by Jayrox

  I am looking for the best way to handle a database of many-to-many relationships in PHP and MySQL. Right now I have 2 tables: Users (id, user_name, first_name, last_name) Connections (id_1, id_2) In the User table id is auto incremented on add and user_name is unique, but can be changed. Unfortunately, I don't have control over the user_name and its ability to be changed, but I must account for it. The Connections table is obviously, user1 and user2's id. The connection table needs to account for these possible relations: user1 --> user2 (user 1 friends with user 2 but not user2 friends with user1) user2 --> user1 (user 2 friends with user 1 but not user1 friends with user2) user1 <--> user2 (user 1 and user 2 mutually friends) user1 <-!-> user2 (user 1 and user 2 not friends) That part is not the problem, The problem I am having with is keeping these relations unique when and if they change in batches. Possible solution 1: delete all of user 1's relations and readd them with the updated list. I think this might be too slow for my needs. Solution 2? Anyone else encounter this problem? How should I best handle this? update: distinguishing relationships: i handle relationships like this: user1, user2 user1, user3 user2, user1 in that example the following is true: user1 follows user2 and user3 user2 only follows user1 but doesn't follow user3 user3 doesn't follow either user1 or user2

• Is saving to database just to get an ID a bad hack?

  - by Narsil

  I hope the title is not too confusing. I am trying to make folders with linq-to-sql objects' IDs. Actually I have to create folders before I should save them. I will use them to keep user uploaded files. As you can see I have to create the folder with the FileID before I can save it there. So I just save a record which will be edited or maybe deleted File newFile = new File(); ...//add some values to fields so they don't throw rule violations db.AddFile(newFile); db.Save(); System.IO.Directory.CreateDirectory("..Uploads/"+newFile.FileId.ToString()); After that I will have to edit some fields and save again. Of course user might stop upload and I would have to delete it. I know I can write a stored procedure to get the next available FileID but some other upload happening at the same time would get the same number. So they would write in same directory which is a thing I don't want. Should I go on with this, would there be some problems? Can you think of a better way?

When I search for the user using the PeopleSearchBoxEx web part the user comes up but when I click on there name I get the error: Server Error in '/' Application. -------------------------------------------------------------------------------- User not found.

• Play framework does not return page and static content

  - by Anton

  I'm using play framework in production for one of my web projects. From time to time Play does not render main page or does not return some of the static content files. I have attached few screenshots below. First screenshot displays firebug console, loading of the site is stucked at the beginning, when serving home page. Second screenshot display fiddler console, when 2 static resources are not loading. This issue is hard to reproduce, it happens 1 of 15 time, I have to delete cache data and reload page. (pressing CRTL-F5 in FF). Issue can be reproduced in most of the browsers. Initially, I was thinging that there is something wrong with hosting provider. But I have changed hosting provided and issue has not gone. Version of the play is 1.2.2. Play is running as standalone server. Not sure, but probably deploying Play to Jetty/Tomcat/Resin would help. Also I'm thinging about rewriting application to another stack (well-known for me - j2ee, spring, whatever) I have no idea how to debug and resolve this issue. Any clue ? Has anyone faced same issue with Play before ?

• Database Error Handling: What if You have to Call Outside service and the Transaction Fails?

  - by Ngu Soon Hui

  We all know that we can always wrap our database call in transaction ( with or without a proper ORM), in a form like this: $con = Propel::getConnection(EventPeer::DATABASE_NAME); try { $con->begin(); // do your update, save, delete or whatever here. $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } This way would guarantee that if the transaction fails, the database is restored to the correct status. But the problem is that let's say when I do a transaction, in addition to that transaction, I need to update another database ( an example would be when I update an entry in a column in databaseA, another entry in a column in databaseB must be updated). How to handle this case? Let's say, this is my code, I have three databases that need to be updated ( dbA, dbB, dbc): $con = Propel::getConnection("dbA"); try { $con->begin(); // update to dbA // update to dbB //update to dbc $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } If dbc fails, I can rollback the dbA but I can't rollback dbb. I think this problem should be database independent. And since I am using ORM, this should be ORM independent as well. Update: Some of the database transactions are wrapped in ORM, some are using naked PDO, oledb ( or whatever bare minimum language provided database calls). So my solution has to take care this. Any idea?

• FluentNHibernate, getting 1 column from another table

  - by puffpio

  We're using FluentNHibernate and we have run into a problem where our object model requires data from two tables like so: public class MyModel { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual int FooId { get; set; } public virtual string FooName { get; set; } } Where there is a MyModel table that has Id, Name, and FooId as a foreign key into the Foo table. The Foo tables contains Id and FooName. This problem is very similar to another post here: http://stackoverflow.com/questions/1896645/nhibernate-join-tables-and-get-single-column-from-other-table but I am trying to figure out how to do it with FluentNHibernate. I can make the Id, Name, and FooId very easily..but mapping FooName I am having trouble with. This is my class map: public class MyModelClassMap : ClassMap<MyModel> { public MyModelClassMap() { this.Id(a => a.Id).Column("AccountId").GeneratedBy.Identity(); this.Map(a => a.Name); this.Map(a => a.FooId); // my attempt to map FooName but it doesn't work this.Join("Foo", join => join.KeyColumn("FooId").Map(a => a.FooName)); } } with that mapping I get this error: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has invalid child element 'join' in namespace 'urn:nhibernate-mapping-2.2'. List of possible elements expected: 'joined-subclass, loader, sql-insert, sql-update, sql-delete, filter, resultset, query, sql-query' in namespace 'urn:nhibernate-mapping-2.2'. any ideas?

• DataTable throwing exception on RejectChanges

  - by Vale

  I found this bug while working with a DataTable. I added a primary key column to a DataTable, than added one row to that table, removed that row, and added row with the same key to the table. This works. When I tried to call RejectChanges() on it, I got ConstraintException saying that value is already present. Here is the example: var dataTable = new DataTable(); var column = new DataColumn("ID", typeof(decimal)); dataTable.Columns.Add(column); dataTable.PrimaryKey = new [] {column }; decimal id = 1; var oldRow = dataTable.NewRow(); oldRow[column] = id; dataTable.Rows.Add(oldRow); dataTable.AcceptChanges(); oldRow.Delete(); var newRow = dataTable.NewRow(); newRow[column] = id; dataTable.Rows.Add(newRow); dataTable.RejectChanges(); // This is where it crashes I think since the row is deleted, exception should not be thrown (constraint is not violated because row is in deleted state). Is there something I can do about this? Any help is appreciated.
