• Catch enter key press in input text field in AS3

  - by Jonathan Barbero

  Hello, I want to catch the enter key press when the user is filling an input text field in AS3. I think I have to do something like this: inputText.addEventListener(Event. ? , func); function func(e:Event):void{ if(e. ? == "Enter"){ doSomething(); } } But I can't find the best way to do this. By the way, the input text has a restriction: inputText.restrict = "0-9"; Should I add the enter key to the restrictions? inputText.restrict = "0-9\n"; Thanks in advance.

• GWT 2.X No resource found for key

  - by Han Fastolfe

  I've developed a GWT app using i18n internationalization. In Host/Dev mode it works fine, but launching GWT compile gives this error: No resource found for key xxx, like below. Compiling module ...rte.RTE Scanning for additional dependencies: file:/home/.../client/i18n/RTEValidationMessages.java Computing all possible rebind results for '...client.i18n.RTEMessages' Rebinding ...client.i18n.RTEMessages Invoking com.google.gwt.dev.javac.StandardGeneratorContext@e7dfd0 Processing interface ...client.i18n.RTEMessages Generating method body for txtIndirizzo3() [ERROR] No resource found for key 'txtIndirizzo3' Messages are loaded with late binding. public class RTEValidationMessages { private RTEMessages additionalMessages; public RTEValidationMessages() { additionalMessages = GWT.create(RTEMessages.class); } } Deleting the method which gives the error, results in another random method with error, say not the method before or after in the interface ...client.i18n.RTEMessages. Help is greatly appreciated.

• D3.js binding an object to data and appending for each key

  - by frshca

  I'm a D3.js newbie and I'm learning how to play around with data. Let's say I have an object with names as keys, and each key has an array of numbers like this: var userdata = { 'John' : [0, 1, 3, 9, 8, 7], 'Harry': [0, 10, 7, 1, 1, 11], 'Steve': [3, 1, 4, 4, 4, 17], 'Adam' : [4, 77, 2, 13, 11, 13] }; For each user, I would like to append an SVG object and then plot the line with the array of values for that user. So here is my assumption of how that would look based on tutorials, but I know it is incorrect. This is to show my limited knowledge and give better understanding of what I'm doing: First I should create the line var line = d3.svg.line().interpolate('basis'); Then I want to bind the data to my body and append an svg element for each key: d3.select('body') .selectAll('svg') .data(userdata) .enter() .append('svg') .append(line) .x(function(d, i) { return i; }) .y(function(d) { return d[i]; }); So am I close??

• Emacs key binding in Eclipse IDE

  - by Peter Delaney

  Hello; I am an Emacs lover probably because I love the key binding and I am able to do things very quickly. I also use Eclipse IDE for my Java/Android/Python/ development because it is free, most of my peers use it, and it works. I find myself switching between emacs and Eclipse and the workflow just isn't great. What I would like to do is setup the key bindings in Eclipse so that they are like Emacs. Can someone suggest the best Eclipse plugin I could use for this. Or can anyone talk about how they've used Eclipse to be more Emacs like. Thanks in advance

• Need to add an array into another array at a specified key value

  - by sologhost

  Ok, I have an array like so, but it's not guaranteed to be laid out in this order all of the time... $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Ok, and I'd like to throw in this array right after the happiness key is defined. I can't use the key of "peace" since it must go directly after happiness, and peace might not come after happiness as this array changes. So here's what I need to add after happiness... $another_array['love'] = array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love' ); So the final output after it gets inputted directly after happiness should look like this: $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'love' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Can someone please give me a hand with this. Using array_shift, array_pop, or array_merge doesn't help me at all, since these go at the beginning and at the end of the array. I need to place it directly after a KEY position within $array. Thanks :)

• Linq : problem with primary key

  - by Nickson

  I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

• Good way to get the key of the highest value of a Dictionary in C#

  - by Arda Xi

  I'm trying to get the key of the maximum value in the Dictionary<double, string> results. This is what I have so far: double max = results.Max(kvp => kvp.Value); return results.Where(kvp => kvp.Value == max).Select(kvp => kvp.Key).First(); However, since this seems a little inefficient, I was wondering whether there was a better way to do this.

• How to reserve a set of primary key identifiers for preloading bootstrap data

  - by Joshua

  We would like to reserve a set of primary key identifiers for all tables (e.g. 1-1000) so that we can bootstrap the system with pre-loaded system data. All our JPA entity classes have the following definition for the primary key. @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false, insertable = false, updatable = false) private Integer id; is there a way to tell the database that increments should start happening from 1000 (i.e. customer specific data will start from 1000 onwards). We support (h2, mysql, postgres) in our environment and I would prefer a solution which can be driven via JPA and reverse engineering DDL tools from Hibernate. Let me know if this is the correct approach

• Unique Key in MySql

  - by Vinodtiru

  I have a table with four Columns. Col1, Col2, Col3, and Col4. Col1, Col2, Col3 is string and Col4 is a integer primary key with Auto Increment. Now my requirement is to have unique combination of Col2 and Col3. I mean to say like. Insert into table(Col1,Col2,Col3) Values('val1','val2','val3'); Insert into table(Col1,Col2,Col3) Values('val4','val2','val3'); the second statement has to throw error as the same combination of 'val2','val3' is present in the table. But i cant make it as a primary key as i need a auto increment column and for that matter the col4 has to be primary. Please let me know a approach by which i can have both in my table. Any kind of help is appreciated. Thanks.

• Create automatically table that is composed by its primery key and 2 other foreign keys

  - by user210481

  I have table A with a primary id, a table B with a primary key id also and another table C with a primary key id and rows Aid and Bid where Aid and Bid are foreign keys of C and the primary keys of A and B respectively. One way of populating these DB would be populating table A, table B and table C separately. I would like to know if there is a more clever way of doing it, where I could populate A first and at the same time I populate B, I can indicate that an entry in C should be also created. Any idea and suggestion on how to populate them is welcome. I'm trying to take advantage of the foreign keys structure Thanks

• There is no Key attribute in EF CTP 5

  - by Spence

  According to the blog post here Data Annotations in the Entity Framework there should be an attribute for a column called "Key" which allows you to mark the primary key of an entity. However I cannot locate this in .Net 3.5 or .Net 4.0. What have I missed? I've included the reference to EntityFramework.dll and I've checked all the attributes under System.ComponentModel.DataAnnotations but I cannot locate it. I have set my project to .Net 4.0 full (not client profile). Any ideas?

• ManyToMany Relation does not create the primary key

  - by Javi

  Hello, I have a ManyToMany relationship between two classes: ClassA and ClassB, but when the table for this relationship (table called objectA_objectB) there is no primary key on it. In my ClassA I have the following: @ManyToMany(fetch=FetchType.LAZY) @OrderBy(value="name") @JoinTable(name="objectA_objectB", joinColumns= @JoinColumn(name="idObjectA", referencedColumnName="id"), inverseJoinColumns= @JoinColumn(name="idObjectB", referencedColumnName="id") ) private List<ClassB> objectsB; and in my ClassB I have the reversed relation @ManyToMany List<ClassA> objectsA; I just want to make a primary key of both id's but I need to change the name of the columns as I do. Why is the PK missing? How can I define it? I use JPA 2.0 Hibernate implementation, if this helps. Thanks.

• Django models: Use multiple values as a key?

  - by Rosarch

  Here is a simple model: class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) Instead of Django creating a default primary key, I would like to use both course and term as the primary key - taken together, they uniquely identify a tuple. Is this allowed by Django? On a related note: I am trying to represent users taking courses in certain terms. Is there a better way to do this? class Course(models.Model): name = models.CharField(max_length=200) requiredFor = models.ManyToManyField(RequirementSubSet, blank=True) offeringSchool = models.ForeignKey(School) def __unicode__(self): return "%s at %s" % (self.name, self.offeringSchool) class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(TakingCourse, blank=True) school = models.ForeignKey(School) class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) class Term(models.Model): school = models.ForeignKey(School) isPrimaryTerm = models.BooleanField()

• What's the best way to authorize a USB Key

  - by ScottCate

  We have an auto update for our software that is installed via USB key (with the auto run). If I wanted to ensure that only authorized USB Keys were used, what's the best way? Our installer is already signed, and it won't run otherwise. But I'm more wanting to inspect the USB Key for a signed installer, and if it's not there, just ignore, or even "Eject" the USB device. And I should be able to tell the difference (in code) between a usb storage device, and say a camera, or keyboard. I'm only wanting to disable non-authorized storage devices. Thank you for your ideas.

• Read nested Lua table who key is a System.Double

  - by Robert Kerr

  Using C# and LuaInterface, I am trying to read a nested table, but am getting a null LuaTable when I try to open the key containing the table. The .lua file: DB = { ["inventory"] = { [10001] = { ["row"] = 140, ["count"] = 20, }, [10021] = { ["row"] = 83, ["count"] = 3, }, [10075] = { ["row"] = 927, ["count"] = 15, }, } } I can successfully foreach the entries under inventory, by opening that table with: LuaTable tbl = lua.GetTable("DB.inventory"); foreach (DictionaryEntry de in tbl) ... What I cannot do is open an inventory item and enumerate its entries the same way. Is this because the key is a System.Double type? This fails: LuaTable tbl = lua.GetTable("DB.inventory.10001"); foreach (DictionaryEntry de in tbl) with an exception, because tbl is null. Effectively, once I enumerate the keys (inventory items), I then want to drill down into the nested table and work with those contents. As you can see, I am not able to get a reference to the nested table the way I am doing it.

• Tables with no Primary Key

  - by Matt Hamilton

  I have several tables whose only unique data is a uniqueidentifier (a Guid) column. Because guids are non-sequential (and they're client-side generated so I can't use newsequentialid()), I have made a non-primary, non-clustered index on this ID field rather than giving the tables a clustered primary key. I'm wondering what the performance implications are for this approach. I've seen some people suggest that tables should have an auto-incrementing ("identity") int as a clustered primary key even if it doesn't have any meaning, as it means that the database engine itself can use that value to quickly look up a row instead of having to use a bookmark. My database is merge-replicated across a bunch of servers, so I've shied away from identity int columns as they're a bit hairy to get right in replication. What are your thoughts? Should tables have primary keys? Or is it ok to not have any clustered indexes if there are no sensible columns to index that way?

• Correct usage of Voldemort as key-value pair?

  - by zengr

  Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.
