  • Array value setting in javascript

    - by Dennis
    Hello. Again I'm still new to this javascript thing, so just would like to know if there is another way of setting the values of an array (just like declaring it); //correct way of declaring an array and reusing var adata = new Array('1','2','3'); //reusing of variable adata[0] = '4'; adata[1] = '5'; adata[2] = '6' ** This part is my question; I want to declare the values of the array just like declaring them to minimize the number of lines; //array declaration var data = new Array('1','2','3'); //reusing of variable data = ['4','5','6']; --- (as an example) I get an error msg "Invalid assignment left-hand side" is this possible? If so, what is the correct syntax? I hope I'm making sense. Thanking you in advance.

  • regular expressions: love or hate or alternatives?

    - by yamspog
    While I can see the value and usefulness of regular expressions, I also find that they are extremely complicated and difficult to create and debug. I am often at the point where I find their usefulness is offset by the difficulty in creating expressions. I am a bit astonished by the fact that there is nothing quite like them and that there hasn't been an effort to recreate them use a more verbose or less arcane syntax. so, are regular expressions here to stay? are there alternatives that are gaining traction? do other people just ignore them and write hundreds of lines of string compare functions?

  • Binding multiple arrays for WHERE IN in PostgreSQL

    - by Alec
    So I want to prepare a query something like: SELECT id FROM users WHERE (branch, cid) IN $1; But I then need to bind a variable length list of arrays like (('a','b'),('c','d')) to it. How do I go about doing this? I've tried using ANY but can't seem to get the syntax right. Cheers, Alec Edit: After some fiddling around, this is valid syntactically: SELECT id FROM users WHERE (branch, cid) = ANY ($1::text[][]); and then binding the string '{{a,b},{c,d}}' to $1 but throws the error "operator does not exist: record = text". Changing 'text' to 'record' then throws "input of anonymous composite types is not implemented". Any ideas?

  • How can I copy a file from VMS to Windows and back again?

    - by Matt Joslin
    I am trying to copy C source files from a vms alpha to a windows machine to allow easier editing of the code. (VMS editor is just a text editor and it would be nice to have syntax highlighting etc) I can copy this across using Exceed FTP and this handles the issue of duplicate filenames with version suffix that vms has: File.c;1 File.c;2 Flle.c;3 But when I open a file I've transferred, all the line breaks have been lost and the entire file is just one line. Can anyone recommend a solution to this or offer any hints? Thanks in advance ps. I need to be able to copy the files back to vms and still maintain format.

  • web developer editor ubuntu

    - by madphp
    Hi, I know theres hundred of questions and answers out there, but cant find one to specifically answer this. I need a web editor that will let me choose a dark themed editor. I understand gvim is one, but im not totally ready to let go of my mouse. I would like something like sublime text editor for windows, but open to other suggestions. The less bloat the best. I dont need a full IDE like eclipse, but willing to compromise, as long as the themes can easily be added. I've tried bluefish, kompozer and not happy with them. Just need a basic text editor that will highlight php syntax on a dark background.

  • for loop in #define

    - by hspim
    #include <stdio.h> #define UNITS {'*', '#', '%', '!', '+', '$', '=', '-'} #define PrintDigit(c, d) (for (i=0; i < c ; i++)putchar(unit[d]);) char unit[] = UNITS; //void PrintDigit(c, element) { // int i; // for (i=0; i < c ; i++) // putchar(unit[element]); //} int main( ) { int i, element=4; PrintDigit(10, element); putchar('\n'); return 0; } I have the function here PrintDigit() which works as expected. When attempting to turn the function into a #define however gcc keeps throwing a syntax error on the for loop. Any idea what the problem is?

  • Objective-C: Protocols

    - by Stu
    I'd like an instance variable object to adopt a protocol. @interface GameScene : Scene <AVAudioPlayerDelegate> { @private Layer *content <CocosNodeOpacity>; } For example I'd like my Layer object to adopt the <CocosNodeOpacity> so that I can get the methods -(GLubyte) opacity; //and -(void) setOpacity: (GLubyte) opacity; for free. The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.

  • Ant 1.8 include or import with nested resource collection

    - by Danny
    I'd like to have Ant automatically include or import resources matching a particular pattern, but I'm really struggling with the syntax. Here's what I've tried: <import> <fileset dir="${basedir}" includes="*-graph.xml" /> </import> However, I just get the error message import requires file attribute or at least one nested resource The documentation for import (and include) both say that you can use a nested resource collection, and the documentation for resource collections says <fileset> is a resource collection. I've Googled and can't find any useful examples at all. I'm using Ant 1.8.1 (verified with ant -version)

  • Auto-Complete Suggestions in Source Code Editor

    - by Jim
    Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

  • RDF Usage Rates for Syndication

    - by David in Dakota
    Is RDF still used widely for content syndication? Specifically, I know only of Slashdot as a large scale website syndicating content in that format (say versus RSS). Understandably this might seem vague to answer so more specifically: Can anyone list any larger sites similar in scale to Amazon or CNN using it? Any web based publishing platforms (Wordpress, Joomla, etc...) that generate syndication feeds with this xml vocabulary. Any other more quantifiable evidence that it is used for syndication online. I understand that RDF may be a parent specification but in this case I'm talking about sites that syndicate content using <rdf as a root element and heavily leveraging elements from the RDF namespace: http://www.w3.org/1999/02/22-rdf-syntax-ns#

  • C++/CLI com-Interop: Exposing a reference type property to VBA

    - by Adam
    After long hours of investigation on exposing C# property that accepts a reference type to VBA, I concluded that it was not possible. In brief, a C# property that is of type double[] or even an object cannot be consumed in VBA like this: ' Compile Error: Function or interface marked as restricted, ' or the function uses an Automation type not supported in Visual Basic oComExposedEarlyBinding.ObjectArray = VBArray ' Run-time error 424: Object required oComExposedEarlyBinding.PlainObject = VBArray Or for more details: C# property exposed to VBA (COM) : Run-time error '424': Object required I would like to know if C++/CLI would support such an option? i.e. Allowing a reference-type property to be exposed to VBA so that a syntax like the above is valid. N.B. You can achieve this by using late binding, but losing the intellisense is not an option.

  • Stored Procedure for Multi-Table Insert Error: Cannot Insert the Value Null into Column

    - by SidC
    Good Evening All, I've created the following stored procedure: CREATE PROCEDURE AddQuote -- Add the parameters for the stored procedure here AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; Declare @CompanyName nvarchar(50), @Addr nvarchar(50), @City nvarchar(50), @State nvarchar(2), @Zip nvarchar(5), @NeedDate datetime, @PartNumber float, @Qty int -- Insert statements for procedure here Insert into dbo.Customers (CompanyName, Address, City, State, ZipCode) Values (@CompanyName, @Addr, @City, @State, @Zip) Insert into dbo.Orders (NeedbyDate) Values(@NeedDate) Insert into dbo.OrderDetail (fkPartNumber,Qty) Values (@PartNumber,@Qty) END GO When I execute AddQuote, I receive an error stating: Msg 515, Level 16, State 2, Procedure AddQuote, Line 31 Cannot insert the value NULL into column 'ID', table 'Diel_inventory.dbo.OrderDetail'; column does not allow nulls. INSERT fails. The statement has been terminated. I understand that I've set Qty field to not allow nulls and want to continue doing so. However, are there other syntax changes I should make to ensure that this sproc works correctly? Thanks, Sid

  • Spring MVC 3.0: Avoiding explicit JAXBElement<> wrapper in method arg

    - by Keith Myers
    I have the following method and want to avoid having to explicitly show the JAXBElement< syntax. Is there some sort of annotation that would allow the method to appear to accept raw MessageResponse objects but in actuality work the same as shown below? I'm not sure how clear that was so I'll say this: I'm looking for some syntactic sugar :) @ServiceActivator public void handleMessageResponse(JAXBElement<MessageResponse> jaxbResponse) { MessageResponse response = jaxbResponse.getValue(); MessageStatus status = messageStatusDao.getByStoreIdAndMessageId(response.getStoreId(), response.getMessageId()); status.setStatusTimestamp(response.getDate()); status.setStatus("Complete"); }

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • REST/ROA Architecture - Send database search/querying/filter/sorting parameters in URL? (>, <, IN, e

    - by DutrowLLC
    I'm building a REST interface to my application using ROA (Resource Oriented Architecture) . I'd like to give the client the ability to specify search parameters in URL. So a client could say "Give me all people who's: "first_name" is equal to "BOB" "age" is greater than "30" sort by "last_name" I was thinking something like: GET /PEOPLE/{query_parameters}/{sort_parameters} ...or perhaps GET /PEOPLE?query=<query_string>&sort=<sort_string> ...but I'm unsure what syntax would be good for specifying in the COLUMN_NAME-OPERATOR-VALUE triplicates. I was thinking perhaps something like: column_name.operator.value So the client could say: GET /PEOPLE?query=first_name.EQUALS.bob&query=age.GREATER_THAN.30&sort=last_name.ASCENDING I really don't want to re-invent the wheel here, are there some accepted ways that this is done? I am using Restlets, I don't know if that makes a difference.

  • For programming content, what simple-to-use-and-setup PHP based blog are the preferred ones?

    - by Johann Gerell
    I've since long wanted a place I can toss my programming related nuggets at. Every day I feel I solve something that I'll surely hit again in a not so distant future, but by then I most certainly will have forgotten about the previous solution I came up with. So I need to blog it down, quick and dirty, for my own documentation and memory's sake. Must be easy to set up and use. Must handle code syntax and highlighting gracefully for a number of languages, but mainly C# and C++. Must be PHP-based, because that's what my host supplies. I know and have used WordPress (not for code, though), but is it really what I want or need?

  • Perl Regex Output only characters that can be used as unix filename

    I wrote a basic mp3 organizing script for myself. I know the power of regex but I suck with the syntax I have the line $outname = "/home/jebsky/safehouse/music/mp3/" . $inital . "/" . $artist . "/" . $year ." - ". $album . "/" . $track ." - ". $artist ." - ". $title . ".mp3"; All I want is a regex to change $outname so that any non safe for filename characters get replaced by an underscore Thanks Jeff

  • How to determine Jet database Engine Type programmatically

    - by MZB
    I have a program which needs to upgrade any Access (Jet) database it opens to JET Version4.x if it isn't already that version. (This enables use of SQL-92 syntax features) Upgrading is (relatively) easy. A call to the JRO.JetEngine object's CompactDatabase method (as described here) should do the trick, but before I do this I need to determine whether an upgrade is required. How do I determine the Jet OLEDB:Engine Type of an existing database? Can this be determined from an open OleDBConnection? Note: I'm talking about database versions, not Jet library versions. C# or .Net solution greatly appreciated.

  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • How do I pass a DBNull value to a parameterized SELECT statement?

    - by Dan
    I have a SQL statement in C# (.NET Framework 4 running against SQL Server 2k8) that looks like this: SELECT [Column1] FROM [Table1] WHERE [Column2] = @Column2 The above query works fine with the following ADO.NET code: DbParameter parm = Factory.CreateDbParameter(); parm.Value = "SomeValue"; parm.ParameterName = "@Column2"; //etc... This query returns zero rows, though, if I assign DBNull.Value to the DbParameter's Value member even if there are null values in Column2. If I change the query to accommodate the null test specifically: SELECT [Column1] FROM [Table1] WHERE [Column2] IS @Column2 I get an "Incorrect syntax near '@Column2'" exception at runtime. Is there no way that I can use null or DBNull as a parameter in the WHERE clause of a SELECT statement?

  • How does mysql define DISTINCT()

    - by goran
    AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best
