  • How can I create a new Person object correctly in Javascript?

    - by TimDog
    I'm still struggling with this concept. I have two different Person objects, very simply: ;Person1 = (function() { function P (fname, lname) { P.FirstName = fname; P.LastName = lname; return P; } P.FirstName = ''; P.LastName = ''; var prName = 'private'; P.showPrivate = function() { alert(prName); }; return P; })(); ;Person2 = (function() { var prName = 'private'; this.FirstName = ''; this.LastName = ''; this.showPrivate = function() { alert(prName); }; return function(fname, lname) { this.FirstName = fname; this.LastName = lname; } })(); And let's say I invoke them like this: var s = new Array(); //Person1 s.push(new Person1("sal", "smith")); s.push(new Person1("bill", "wonk")); alert(s[0].FirstName); alert(s[1].FirstName); s[1].showPrivate(); //Person2 s.push(new Person2("sal", "smith")); s.push(new Person2("bill", "wonk")); alert(s[2].FirstName); alert(s[3].FirstName); s[3].showPrivate(); The Person1 set alerts "bill" twice, then alerts "private" once -- so it recognizes the showPrivate function, but the local FirstName variable gets overwritten. The second Person2 set alerts "sal", then "bill", but it fails when the showPrivate function is called. The new keyword here works as I'd expect, but showPrivate (which I thought was a publicly exposed function within the closure) is apparently not public. I want to get my object to have distinct copies of all local variables and also expose public methods -- I've been studying closures quite a bit, but I'm still confused on this one. Thanks for your help.

  • Groovy Debugging

    - by Vijay Allen Raj
    Groovy Debugging - An Overview:ADF BC developers may express snippets of business logic (like the following) as embedded groovy expressions: default / calculated attribute valuesvalidation rules / conditionserror message tokensLOV input values (VO) This approach has the advantages that: Groovy has a compact, EL-like syntax for expressing simple logicADF has extended this syntax to provide useful built-insembedded Groovy expressions are customizableGroovy debugging support helps improve maintainability of business logic expressed in Groovy.Following is an example how groovy debugging works.Example:This example shows how a script expression validator can be created and the groovy script debugged. It shows Step over, breakpoint functionalities as well as syntax coloring.Let us create a ADFBC application based on Emp and Dept tables, and add a script expression validator based on the script:  if (Sal >= 5000){ //If EmpSal is greater than a property value set on the custom //properties on the root AM //raise a custom exception else raise a custom warning if (Sal >= source.DBTransaction.rootApplicationModule.propertiesMap.salHigh) { adf.error.raise("ExcGreaterThanApplicationLimit"); } else { adf.error.warn("WarnGreaterThan5000"); } } else if (EmpSal <= 1000) { adf.error.raise("ExcTooLow"); }return true;In the Emp.xml Flat editor, place breakpoints at various locations as shown below:Right click the appmodule and click Debug. Enter a value greater than 5000 and click next. You can see the debugging work as shown below:  The code can be also be stepped over and debugged.

  • Creating a timetable using PHP

    - by Big Sal
    I am going to create a little app using PHP that acts as a timetable. I am going to have it going from 9.00am to 5.00pm and through monday to friday. I am still deciding how i want the timetable to function but have this idea though, the user mouses over a section of the timetable, when the user clicks that point, a new event booking window opens up and the user selects the event type and event duration and then saves. Now, I was going to create a 1440 pixel wide table and then have have each hour have 180pixels and each minute of that hour taking up 3 pixels. How would you go about implementing such a thing, and by that i mean, how would you go about making the app so that it knows what time it is when a user clicks a certain portion of the timetable? Im not asking for code or anything like that, I'm just wondering how more experienced developers would go about creating such a timetable because there are a few other ways i have thought about going about this problem but its always nice to hear other peoples ideas about how they would go about solving a problem. Any ideas are welcomed, Thanks.

  • Access restriction on class due to restriction on required library rt.jar?

    - by sal
    I'm attempting to compile Java 1.4 code that was created by IBM's WSDL2Java on Java5 without recreating the stubs and saw this error in Eclipse. I'm under the assumption that the stubs created should just compile as long as the runtime jars are available (they are). Access restriction: The type QName is not accessible due to restriction on required library C:\Program Files\Java\jdk1.5.0_16\jre\lib\rt.jar The full classname is javax.xml.namespace.QName What exactly is going on here? Is this a case where I am trying to refactor a pig from sausage? Am I better off recreating the stubs?

  • Preserving all capitalization in BibTeX

    - by Sal
    I have a huge .bib file generated automatically from Papers for Mac and all the capitalization in the .bib is already the way I want it, but it doesn't have {} brackets on word like RNA. Is there a way to force BibTeX to keep the capitalization rather than change some words to lowercase?

  • Something like PPerl for Ruby?

    - by sal
    I've used PPerl for deamon like processes. This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once. Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.

  • Hibernate Query for a List of Objects that matches a List of Objects' ids

    - by sal
    Given a classes Foo, Bar which have hibernate mappings to tables Foo, A, B and C public class Foo { Integer aid; Integer bid; Integer cid; ...; } public class Bar { A a; B b; C c; ...; } I build a List fooList of an arbitrary size and I would like to use hibernate to fetch List where the resulting list will look something like this: Bar[1] = [X1,Y2,ZA,...] Bar[2] = [X1,Y2,ZB,...] Bar[3] = [X1,Y2,ZC,...] Bar[4] = [X1,Y3,ZD,...] Bar[5] = [X2,Y4,ZE,...] Bar[6] = [X2,Y4,ZF,...] Bar[7] = [X2,Y5,ZG,...] Bar[8] = ... Where each Xi, Yi and Zi represents a unique object. I know I can iterate fooList and fetch each List and call barList.addAll(...) to build the result list with something like this: List<bar> barList.addAll(s.createQuery("from Bar bar where bar.aid = :aid and ... ") .setEntity("aid", foo.getAid()) .setEntity("bid", foo.getBid()) .setEntity("cid", foo.getCid()) .list(); ); Is there any easier way, ideally one that makes better use of hibernate and make a minimal number of database calls? Am I missing something? Is hibernate not the right tool for this?

  • 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?

  • Merge Records in Session bean by using ADF Drag/Drop

    - by shantala.sankeshwar
    This article describes how to merge multiple selected records in Session Bean using ADF drag & drop feature. Below described is simple use case that shows how exactly this can be achieved. Here we will have table & user input field.Table shows  EMP records & user input field accepts Salary.When we drag & drop multiple records on user input field,the selected records get updated with the new Salary provided. Steps: Let us suppose that we have created Java EE Web Application with Entities from Emp table.Then create EJB Session Bean & generate Data control for the same. Write a simple code in sessionEJBBean & expose this method to local interface :  public void updateEmprecords(List empList, Object sal) {       Emp emp = null;       for (int i = 0; i < empList.size(); i++)       {        emp = em.find(Emp.class, empList.get(i));         emp.setSal((BigDecimal)sal);       }      em.merge(emp);   } Now let us create updateEmpRecords.jspx page in viewController project & Drop empFindAll object as ADF Table Define custom SelectionListener method for the table :   public void selectionListener(SelectionEvent selectionEvent)     {     // This method gets the Empno of the selected record & stores in the list object      UIXTable table = (UIXTable)selectionEvent.getComponent();      FacesCtrlHierNodeBinding fcr      =(FacesCtrlHierNodeBinding)table.getSelectedRowData();      Number empNo = (Number)fcr.getAttribute("empno") ;      this.getSelectedRowsList().add(empNo);     }Set table's selectedRowKeys to #{bindings.empFindAll.collectionModel.selectedRow}"Drop inputText on the same jspx page that accepts Salary .Now we would like to drag records from the above table & drop that on the inputtext field.This feature can be achieved by inserting dragSource operation inside the table & dropTraget operation inside the inputText:<af:dragSource discriminant="tab"/> //Insert this inside the table<af:inputText label="Enter Salary" id="it13" autoSubmit="true"       binding="# {test.deptValue}">       <af:dropTarget dropListener="#{test.handleTableDrop}">       <af:dataFlavor        flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"    discriminant="tab"/>       </af:dropTarget>       <af:convertNumber/> </af:inputText> In the above code when the user drags & drops multiple records on inputText,the dropListener method gets called.Goto the respective page definition file & create updateEmprecords method action& execute action dropListener method code:        public DnDAction handleTableDrop(DropEvent dropEvent)        {          //Below code gets the updateEmprecords method,passes parameters & executes method            DataFlavor<RowKeySet> df = DataFlavor.getDataFlavor(RowKeySet.class);            RowKeySet droppedKeySet = dropEvent.getTransferable().getData(df);            if (droppedKeySet != null && droppedKeySet.size() > 0)           {                  DCBindingContainer bindings =                  (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();                  OperationBinding updateEmp;                  updateEmp= bindings.getOperationBinding("updateEmprecords");                  updateEmp.getParamsMap().put("sal",                  this.getDeptValue().getAttributes().get("value"));                            updateEmp.getParamsMap().put("empList", this.getSelectedRowsList());                  updateEmp.execute(); //Below code performs execute operation to refresh the updated records                 OperationBinding executeBinding;                 executeBinding= bindings.getOperationBinding("Execute");                 executeBinding.execute(); AdfFacesContext.getCurrentInstance().addPartialTarget(dropEvent.getDragComponent());                this.getSelectedRowsList().clear();          }                 return DnDAction.NONE;        }Run updateEmpRecords.jspx page & enter any Salary say '5000'.Select multiple records in table & drop these selected records on the inputText Salary. Note that all the selected records salary value gets updated to 5000.Technorati Tags: ADF Drag and drop,EJB Session bean,ADF table,inputText,DropEvent

  • Difference between EJB Persist & Merge operation

    - by shantala.sankeshwar
    This article gives the difference between EJB Persist & Merge operations with scenarios.Use Case Description Users working on EJB persist & merge operations often have this question in mind " When merge can create new entity as well as modify existing entity,then why do we have 2 separate operations - persist & merge?" The reason is very simple.If we use merge operation to create new entity & if the entity exists then it does not throw any exception,but persist throws exception if the entity already exists.Merge should be used to modify the existing entity.The sql statement that gets executed on persist operation is insert statement.But in case of merge first select statement gets executed & then update sql statement gets executed.Scenario 1: Persist operation to create new Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control. Drop Emp Object(Expand SessionEJBLocal->Constructors under Data Controls) as ADF Parameter form in jspx pageDrop persistEmp(Emp) as ADF CommandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & provide values for Emp,click on 'persistEmp' button.New Emp record gets created.So when we execute persist operation only insert sql statement gets executed :INSERT INTO EMP (EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR) VALUES (?, ?, ?, ?, ?, ?, ?, ?)    bind => [2, null, null, e2, null, 10, null, null]Scenario 2: Merge operation to modify existing Emp recordLet us suppose that we have a Java EE Web Application created with Entities from Emp table & have created session bean with data control.Drop empFindAll() Object as ADF form on jspx page.Drop mergeEmp(Emp) operation as commandButton & provide #{bindings.EmpIterator.currentRow.dataProvider} as the value for emp parameter.Then run this page & modify values for Emp record,click on 'mergeEmp' button.The respective Emp record gets modified.So when we execute merge operation select & update sql statements gets executed :SELECT EMPNO, COMM, HIREDATE, ENAME, JOB, DEPTNO, SAL, MGR FROM EMP WHERE (EMPNO = ?) bind => [7566]UPDATE EMP SET ENAME = ? WHERE (EMPNO = ?) bind => [KINGS, 7839]

Does it have a solution or should I just choose to import from an excel sheet, thats better? Tried with if else and functions fun1 <- function() { print('You have selected option 1') my <- as.character((readline("enter the variable name \n"))) gg1 <- aggregate(cbind(get(my))~Mi+hours,a, FUN=mean) names(gg1)[3] <- my #print(names(gg1)) ggplot (gg1,aes_string(x="hours",y=(my),group="Mi",color="Mi")) + geom_point() } my <- as.integer(readline("enter a number")) ifelse(my == 1,fun1(),"") ifelse(my == 2,print ("its 2"),"") ifelse(my == 3,print ("its 3"),"") ifelse(my != (1 || 2|| 3) ,print("wrong number"),"") Not working either...:(

  • SQL Server: Output an XML field as tabular data using a stored procedure

    - by Pawan
    I am using a table with an XML data field to store the audit trails of all other tables in the database. That means the same XML field has various XML information. For example my table has two records with XML data like this: 1st record: <client> <name>xyz</name> <ssn>432-54-4231</ssn> </client> 2nd record: <emp> <name>abc</name> <sal>5000</sal> </emp> These are the two sample formats and just two records. The table actually has many more XML formats in the same field and many records in each format. Now my problem is that upon query I need these XML formats to be converted into tabular result sets. What are the options for me? It would be a regular task to query this table and generate reports from it. I want to create a stored procedure to which I can pass that I need to query "<emp>" or "<client>", then my stored procedure should return tabular data.

  • how to write unicode hello world in C on windows

    - by hatchetman82
    im tyring to get this to work: #define UNICODE #define _UNICODE #include <wchar.h> int main() { wprintf(L"Hello World!\n"); wprintf(L"£?, ?, ?!\n"); return 0; } using visual studio 2008 express (on windows xp, if it matters). when i run this from the command prompt (started as cmd /u which is supposed to enable unicode ?) i get this: C:\dev\unicodevs\unicodevs\Debugunicodevs.exe Hello World! -ú8 C:\dev\unicodevs\unicodevs\Debug which i suppose was to be expected given that the terminal does not have the font to render those. but what gets me is that even if i try this: C:\dev\unicodevs\unicodevs\Debugcmd /u /c "unicodevs.exe output.txt" the file produced (even though its UTF-8 encoded) looks like: Hello World! £ì the source file itself is defined as unicode (encoded in UTF-8 without BOM). the compiler output when building: 1------ Rebuild All started: Project: unicodevs, Configuration: Debug Win32 ------ 1Deleting intermediate and output files for project 'unicodevs', configuration 'Debug|Win32' 1Compiling... 1main.c 1.\main.c(1) : warning C4005: 'UNICODE' : macro redefinition 1 command-line arguments : see previous definition of 'UNICODE' 1.\main.c(2) : warning C4005: '_UNICODE' : macro redefinition 1 command-line arguments : see previous definition of '_UNICODE' 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wchar.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtdefs.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h 1C:\Program Files\Microsoft Visual Studio 9.0\VC\include\sal.h(108) : warning C4001: nonstandard extension 'single line comment' was used 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\crtassem.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\vadefs.h 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\swprintf.inl 1Note: including file: C:\Program Files\Microsoft Visual Studio 9.0\VC\include\wtime.inl 1Linking... 1Embedding manifest... 1Creating browse information file... 1Microsoft Browse Information Maintenance Utility Version 9.00.30729 1Copyright (C) Microsoft Corporation.
