• Help with proper character encoding.

  - by mmattax

  I have a HTML form that is sometimes submitted with accented characters: à, è, ì, ò, ù I have a PHP script that exports these form submissions into CSV format, when I look at the CSV format in a text editor (vim or notepad for example) the characters look fine, but when opened with Open Office or Word, I get some funky results: ????? I am also passing these submission to salesforce and am getting an error: "The entity "Atilde" was referenced, but not declared." What can I do to ensure portability of my CSV file? What's the proper way to handle the encoding? My HTML file is content-type is set as: Content-Type: text/html; charset=utf-8 Data is being stored in MySQL as latin1_swedish_ci collation.

• ASP.NET MVC Filters: How to set Viewdata for Dropdown based on action parameter

  - by CRice

  Hi, Im loading an entity 'Member' from its id in route data. [ListItemsForMembershipType(true)] public ActionResult Edit(Member someMember) {...} The attribute on the action loads the membership type list items for a dropdown box and sticks it in viewdata. This is fine for add forms, and search forms (it gets all active items) but I need the attribute to execute BASED ON THE VALUE someMember.MembershipTypeId, because its current value must always be present when loading the item (i.e. all active items, plus the one from the loaded record). So the question is, what is the standard pattern for this? How can my attribute accept the value or should I be loading the viewdata for the drop down in a controller supertype or during model binding or something else? It is in an attribute now because the code to set the viewdata would otherwise be duplicated in each usage in each action.

• Get records based on child condition

  - by Shawn Mclean

  In LINQ To Entities: How do I get the records (including both child and parent) based on a condition of the child in a one to many. My structure is set up as follows: GetResources() - returns a list of Resources. GetResources().ResourceNames - this is the child, which is an entity collection. GetResources().ResourceNames - a property of one record of this child is Name. I'd like to construct something like this: return (from p in repository.GetResources() where p.ResourceNames.Exist(r => r.Name.Contains(text, StringComparison.CurrentCultureIgnoreCase)) select p).ToList(); but of course, Exist doesn't exist. thanks.

• What's the equivalent in C# of this VB code on an Outlook form?

  - by wes

  Basically, how do I link an Outlook form and a C# back end? In VB you can write on the form Sub ButtonName_Click() Dim Recipients With Item.GetInspector.ModifiedFormPages("Message") Set Recipients = .Controls("To") End With End Sub which will fire whenever the button named "ButtonName" on the form is clicked and will set the variable Recipients to a string of whatever is in the To text box. Now I have a custom form, and I have a VS C# Outlook Add-in, and they're two separate things. I've got an event handler that can catch MailItem objects, but I don't know how to handle custom form button clicks or even how to access elements on the form. EDIT - Just to clarify, the custom form was created in Outlook and then its .ofs was imported into VS. Both Outlook and VS are 2010.

• How to retrieve Google Appengine Objects by id (Long value) ?

  - by David

  Hi, i have declared an entity the following way: public class MyEntity { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long id; @Persistent private String text; //getters and setters } Now I want to retrieve the objects using the id. I tried to manage it from the Google Appengine Data Viewer with "SELECT * FROM MyEntity Where id = 382005" or via a query in a servlet. I get no results returned. But i know for sure that the object with the id exists (i made a jsp which queries all objects in the db and displays them in the db). So what is wrong in my query? Am I querying the wrong field? The Google Appengine Data Viewer names the field "ID/name" and it has the value "id=382005". Do I have to query with this names? I've tried but it didn't work out :(

• How do I convert a single char in string to an int

  - by Guest

  Keep in mind, if you choose to answer the question, I am a beginner in the field of programming and may need a bit more explanation than others as to how the solutions work. Thank you for your help. My problem is that I am trying to do computations with parts of a string (consisting only of numbers), but I do not know how to convert an individual char to an int. The string is named "message". for (int place = 0; place < message.size(); place++) { if (secondPlace == 0) { cout << (message[place]) * 100 << endl; } } Thank you.

• Get a list of events owned by a facebook page

  - by Tom Wright

  Does anyone know how I can get a list of events owned (created) by a Facebook page? I seem to be able to use the "graph api" to generate a list of the events an entity is attending. I also looked at FQL, but it seems to require that the 'where' clause is an indexable field (and, naturally, the id is the only indexable field). For bonus points, we'd be able to do this without any authentication. (Though I'm resigned to the fact that I'm likely going to need at least a permanent access_token.) If anyone know how to do this I'd be eternally grateful.

• Working effectively with unit tests / Anyone tried the in-assembly approach?

  - by CodingCrapper

  I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

• JSF - database character encoding

  - by wheelie

  Hi there, I have a Java Web application using GlassFish 3, JSF2.0 (facelets) and JPA (EclipseLink). The problem I'm facing, is that if I'm saving entities to the database with the update() method, String data loses integrity; '?' is shown instead of some characters. The server, pages and database is/are configured to use UTF-8. After I post form data, the next page shows the data correctly. Furthermore it "seems" in debug that the String property of the current entity stores the correct value too. Dunno if NetBeans debug can be trusted; might be that it decodes correctly, however it's incorrect. Any help would be appreciated, thanks in advance! Daniel

• mapping 'value object' collection in (Fluent) NHibernate

  - by adrin

  I have the following entity public class Employee { public virtual int Id {get;set;} public virtual ISet<Hour> XboxBreakHours{get;set} public virtual ISet<Hour> CoffeeBreakHours {get;set} } public class Hour { public DateTime Time {get;set;} } (What I want to do here is store information that employee A plays Xbox everyday let's say at 9:00 13:30 and has a coffee break everyday at 7:00 12:30 18:00) - I am not sure if my approach is valid at all here. The question is how should my (ideally fluent) mappings look like here? It is not necessary (from my point of view) for Hour class to have Id or be accessible from some kind of repository.

• how to get transform a local image to a web accessable image

  - by hguser

  Hi: Generally,if we want to display a image in the web page,we give the uri of the image resource like: http://host:port/image/xxx.jpg. Now,there are some images in my file system,and I save its absolute path in the db. Like this; id name address image 1 xxxx xxxx C:/images/xxx.jpg Now if the entity is retrived,its image should be displayed in the page. How to make it? What I thought is copy the image under the web server dir,then build its url,then the page can render it. But I wonder if this is a good idea? Is there any other way?

• Bash - Adding 0's in the middle of a file name

  - by user596691

  I have a bunch of files which are named: mem0.csv mem1.csv . . . . mem153.csv . . . They are all in the same folder. When I do ls in the folder they appear in an order of mem0.csv mem1.csv mem10.csv mem100.csv . . . mem2.csv mem20.csv . . . I want to create a bash script to push 0's between mem and the number. I figure that I need to add 0's until all the filenames are of the same length only problem is that I don't know how to do this.

• Silverlight Bind to TextBlock from RIA Services

  - by DaRKoN_

  I've a TextBlock that looks like so: <TextBlock Text="{Binding Name}" /> This is inside a <Canvas> with the DataContext set to MyClient which is in the ViewModel: public Client MyClient { get; private set; } // This is a RIA Entity, hence supports INotifyPropertyChanged public ViewModel() { MyClient = new Client(); LoadOperation<Client> loadClient = RiaContext.Load<Client>(RiaContext.GetClientsQuery()); loadClient.Completed += new EventHandler(loadClient_Completed); } void loadClient_Completed(object sender, EventArgs e) { MyClient = DB.Clients.Single(); } Setting MyClient like the above does not raise the PropertyChanged event. As such the UI is never updated.

• PHP5: restrict access to function to certain classes

  - by Tim

  Is there a way in PHP5 to only allow a certain class or set of classes to call a particular function? For example, let's say I have three classes ("Foo", "Bar", and "Baz"), all with similarly-named methods, and I want Bar to be able to call Foo::foo() but deny Baz the ability to make that call: class Foo { static function foo() { print "foo"; } } class Bar { static function bar() { Foo::foo(); print "bar"; } // Should work } class Baz { static function baz() { Foo::foo; print "baz"; } // Should fail } Foo::foo(); // Should also fail There's not necessarily inheritance between Foo, Bar, and Baz, so the use of protected or similar modifiers won't help; however, the methods aren't necessarily static (I made them so here for the simplicity of the example).

• Is there a simple script to convert C++ enum to string?

  - by Edu Felipe

  Suppose we have some named enums: enum MyEnum { FOO, BAR = 0x50 }; What I googled for is a script (any language) that scans all the headers in my project and generates a header with one function per enum. char* enum_to_string(MyEnum t); And a implementation with something like this: char* enum_to_string(MyEnum t){ switch(t){ case FOO: return "FOO"; case BAR: return "BAR"; default: return "INVALID ENUM"; } } The gotcha is really with typedefed enums, and unnamed C style enums. Does anybody know something for this? EDIT: The solution should not modify my source, except for the generated functions. The enums are in an API, so using the solutions proposed until now is just not an option.

• appending text to all files that starts with a string

  - by learner135

  How do I append a string to all the files in a directory that starts with a particular string? I tried, cat mysig >> F* But instead of appending contents of mysig to all files starting with F, it creates a file named "F*". Obviously wildcard doesn't seem to work. Any alternatives? Thanks in advance. Edit: Also how do I delete this newly created file "F*" safely?. Using rm F* would delete all the files starting with F which I wouldn't want.

• Best Ruby ORM for Wrapping around Legacy MSSQL Database?

  - by Technocrat

  Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support mssql through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in MSSQL. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the MSSQL app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with MSSQL but never to do anything quite like this. Any suggestions?

• R matrix handling expressions aren't evaluated in a function or a "for" loop - Column extract doesn't seem to work

  - by Sal Leggio

  I have an R matrix named ddd. When I enter this, everything works fine: i <- 1 shapiro.test(ddd[,y]) ad.test(ddd[,y]) stem(ddd[,y]) print(y) The calls to Shapiro Wilk, Anderson Darling, and stem all work, and extract the same column. If I put this code in a "for" loop, the calls to Shapiro Wilk, and Anderson Darling stop working, while the the stem & leaf call and the print call continue to work. for (y in 7:10) { shapiro.test(ddd[,y]) ad.test(ddd[,y]) stem(ddd[,y]) print(y) } The decimal point is 1 digit(s) to the right of the | 0 | 0 0 | 899999 1 | 0 [1] 7 The same thing happens if I try and write a function. SW & AD do not work. The other calls do. D <- function (y) { + shapiro.test(ddd[,y]) + ad.test(ddd[,y]) + stem(ddd[,y]) + print(y) } D(9) The decimal point is at the | 9 | 000 9 | 10 | 00000 [1] 9 Why don't all the calls behave the same way?
