• FLEX: how to ignore MouseEvents from the container ?

  - by Patrick

  hi, I've some objects on the canvas, and I added eventListeners to these objects for MOUSE_UP event. I'm know checking if it works by tracing e.target.name, and I found out that the event is triggered twice, before on the element container (Canvas) and then the element itself. I read several times the documentation about Capture, Bubbling etc.. but I don't understand how to trigger the events only from the element itself... child.addEventListener(MouseEvent.MOUSE_UP, updateSelectedTags); private function updateSelectedTags(e:MouseEvent):void { Alert.show(e.currentTarget.name); //I have 2 alerts, one for canvas, the other one for the child } } thanks

• is NATURAL JOIN any better than SELECT FROM WHERE in terms of performance ?

  - by ashy_32bit

  Today I got into a debate with my project manager about Cartesian products. He says a 'natural join' is somehow much better than using 'select from where' because the later cause the db engine to internally perform a Cartesian product but the former uses another approach that prevents this. As far as I know, the natural join syntax is not any different in anyway than 'select from where' in terms of performance or meaning, I mean you can use either based on your taste. SELECT * FROM table1,table2 WHERE table1.id=table2.id SELECT * FROM table1 NATURAL JOIN table2 please elaborate about the first query causing a Cartesian product but the second one being somehow more smart

• Vim plugin only works when file is provided as arg to launch command

  - by nsfyn55

  I am using the plugin java_getset.vim. The issue is that the plugin's commands are only available when I launch vim with the file as an argument. user@machine~: vim myfile.java If launch vim and use command-t or NerdTree to open the file in a buffer the plugin's commands are not accessible. All the filetype detection stuff is configured and working(I have syntax highlighting and indentation). The plugin source appears to be written to the letter according the the vim docs for a filetype plugin. Can anyone help me understand what changes a can make so that I can use this plugin in conjunction with Command-t?

• Django: Is it possible to attach media files (css, javascript etc) to a View-class?

  - by mrmclovin

  I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory. Does anyone know if it's possible? Thanks!

• See queries that hit SQL

  - by Shaded

  I have a really basic stupid easy question about sql... and I'll probably get -100 points... but here it goes anyway... Is there a way using sql 2008 Management Studio to look at the queries that hit the server? I'm trying to debug a program and I get messages like "Incorrect syntax near the keyword 'AND'". Since the queries are being dynamically generated it's a hassle to figure out what is going to the server. Any help is appreciated!

• Query MS Access database in VB 2008

  - by Logan

  Hi, I added an Access database as a Data Source in VB 2008. I want to query this database and use the information in various ways throughout the program. For example, there is an Employee table with first/last names of employees. I have a combobox on my form that I want to display all of the employees. So I want to query the database for all the rows in the Employee table, and add them to the combobox as I go. I am familiar with SQL Syntax, so I am not asking how to write the query itself, but rather how to fetch rows in VB code (mimicking php's mysql_fetch_assoc and mysql_connect essentially) Thanks! Edit: Also, I want to know if I can query a DB if I don't add it as a data source (if I know the path name of the database)

• including a string as a parameter to a function in a header file? c++

  - by Nara

  hello everyone, total newbie is here :) i have this header file, zeeheader.h, and i wrote some classes in it, i'm having problems giving a string as a parameter to one of the functions: class DeliTest { public: void DeliCheck(Stack*,string); void ComCheck (unsigned,string); bool EofCheck (unsigned,string); }; as i was implementinng it in the cpp file, i added #include to it, it seemed to be working, for example : as i was writing the "data." i got the "length()" appear by the intellisense, so i thought that it was working, but it wasn't. i got errors like: syntax error : identifier 'string' overloaded member function not found in 'DeliTest' this is one of the fucntions in the cpp file: bool DeliTest::EofCheck(unsigned i, string data) { if (i == data.length()-1) return 1; return 0; } am i supposed to be adding something to the header file??

• Finding whether a value is equal to the value of any array element in MATLAB

  - by James

  Hi, Can anyone tell me if there is a way (in MATLAB) to check whether a certain value is equal to any of the values stored within another array? The way I intend to use it is to check whether an element index in one matrix is equal to the values stored in another array (where the stored values are the indexes of the elements which meet a certain criteria). So, if the indices of the elements which meet the criteria are stored in the matrix below: criteriacheck = [3 5 6 8 20]; Going through the main array (called array) & checking if the index matches: for i = 1:numel(array) if i == 'Any value stored in criteriacheck' ... "Do this" end Does anyone have an idea of how I might go about this? Thanks in advance

• JQuery - How do I count the number of elements selected by a selector?

  - by Josh

  I am using $().fadeOut() to fade items out in a list ( < li < /li). When the list is empty I wish to hide a parent object. I plan on doing this by checking in my trigger event that fades the list if the count of the objects is 0 then hide the parent element. I can use the fadeOut callback to remove the elements if necessary. The to the point question: How do I select li tags inside a ul and then get the total count of them using jquery?

• MySQL Query : Advise Needed.

  - by Rachel

  "SELECT id as Id from dbTable WHERE code = ? AND CURDATE() BETWEEN start_date AND end_date AND offerId IN ('12321', '12124')"; //Passing arguments for the query $args = array_merge(array(51342),$offerid); //Execute the prepared query $statement->execute($args); Now array(51342) represents combination of code+value, aside my database has value, code columns and so I want a query which would look logically like "SELECT id as Id from dbTable WHERE code and value (Note here I do not know the syntax, what am looking at is (code+value = ?), please advise on query) = ?

• Can return and else statements be used interchangable in CFScript?

  - by Mel

  I would like to know your opinion on using return and else statements interchangeably in CFScript. I generally use the following syntax: if (something) { // Do something } else { // Do something else } It recently occurred to me I could do this instead: if (something) { // Do something return; } // Do something else Would those two styles yield a different end result? I like not having to wrap code in an else statement. My thinking is that if the if statement evaluates true and returns, the code below it will not run. If it does not evaluate true, then the code below it will run regardless of whether it is wrapped in an else statement or not. Does that sound write?

• Ruby does not run code correctly

  - by seefour

  I run this basic code in Ruby (on Windows): def hello () puts 'test' end hello and the Interpreter throws me this error: app.ru:1: syntax error, unexpected tIDENTIFIER, expecting $end hello puts 'test' It seems like Ruby is skipping lines? I've tried various encoding formats, other code and it still gives me an error similar to this. Why is it happening? EDIT The suggestions were to either use different editors or semi-colons to see if the lines were an issue. The version is also new - 1.9.3p327, so that shouldn't have been a problem. Parentheses aren't a problem either.

• Abstract class and operator!= in c++

  - by Alessandro Teruzzi

  Hi All, I have problem implementing the operator!= in a set class deriving from an abstact one. The code looks like this: class Abstract { public: //to make the syntax easier let's use a raw pointer virtual bool operator!=(const Abstract* other) = 0; }; class Implementation { SomeObject impl_; //that already implement the operator!= public: bool operator!=(const Abstract* other) { return dynamic_cast<Implementation*>(other)->impl_ != this->impl_; } }; This code works but it has the drawback to use dynamic_cast and I need to handle error in casting operation. This is a generic problem that occur when a function of a concrete class it is trying to using some internal information (not available at the abstract class level) to perform a task. Is there any better way to solve this kind of problem? Cheers

• Can a thread call wait() on two locks at once in Java (6)

  - by Dr. Monkey

  I've just been messing around with threads in Java to get my head around them (it seems like the best way to do so) and now understand what's going on with synchronize, wait() and notify(). I'm curious about whether there's a way to wait() on two resources at once. I think the following won't quite do what I'm thinking of: synchronized(token1) { synchronized(token2) { token1.wait(); token2.wait(); //won't run until token1 is returned System.out.println("I got both tokens back"); } } In this (very contrived) case token2 will be held until token1 is returned, then token1 will be held until token2 is returned. The goal is to release both token1 and token2, then resume when both are available (note that moving the token1.wait() outside the inner synchronized loop is not what I'm getting at). A loop checking whether both are available might be more appropriate to achieve this behaviour (would this be getting near the idea of double-check locking?), but would use up extra resources - I'm not after a definitive solution since this is just to satisfy my curiosity.

• Is this the right way of handling command line arguments?

  ask_username = True ask_password = True ask_message = True ask_number = True def Usage(): print '\t-h, --help: View help' print '\t-u, --username: Username' print '\t-p, --password: Password' print '\t-n, --number: numbber to send the sms' print '\t-m, --message: Message to send' sys.exit(1) opts, args = getopt(sys.argv[1:], 'u:p:m:n:h',["username=","password=","message=","number=","help"]) print opts, args for o,v in opts: if o in ("-h", "--help"): Usage() elif o in ("-u", "--username"): username = v ask_username = False elif o in ("-p", "--password"): passwd = v ask_password = False elif o in ("-m", "--message"): message = v ask_message = False elif o in ("-n", "--number"): number = v ask_number = False #Credentials taken here if ask_username: username = raw_input("Enter USERNAME: ") if ask_password: passwd = getpass() if ask_message: message = raw_input("Enter Message: ") if ask_number: number = raw_input("Enter Mobile number: ") I dont think it is, because I am using 4 objects just for checking if command line argument was provided...

• "Inconsistent accessibility" on class definition

  - by TWood

  I'm adding some bindable CLR properties to my ongoing WPF application in my App class and I can't compile because of this inconsistent accessibility error. Inconsistent Accessibility: Property type 'SomeProj.Error' is less accessible than property 'SomeProj.App.LatestError' To fix this error I had to change class Error to public class Error. In VB, classes were assumed public and most of the time omitted that access modifier. Is this not the case in C# as well? I only recently made the vb-c# jump and little nuances like this in the syntax slow me down.

• Given a user control with a form containing validation can I validate entirely server side?

  - by JoshBaltzell

  We have an existing User Control that was built to dynamically generate a web form for an end user. This form includes required field validators, custom validators that use server side code and Regular Expression validatiors. We now have a need to use all these validators to verify that all the needed data is entered when using a separate ordering process that cannot be validated in the same way, but has the same validation requirements before it is added to the database. I would like to use this user control to validate the input by passing it all the values and checking the validation summary. The only way I know how to do this is to render it to a page on the client side and trigger the form submit. Is there any way to populate and validate a web form entirely on the server side?

• How are builds deployed into QA->Staging->Production for ASP.NET Web Applications?

  - by CodeToGlory

  Secondary questions are How do we best utilize SCM in the build process? How are code files labed and branched? Should we the .csproj and .sln files for build? How flexible are these when deploying to several environments? I know these are msbuild files. But as we add new files, this can become a bottlenect of updating and maintaining these .csproj files in SCM. How is rollback done in case of failed builds that QA missed testing etc,etc., Are there any good articles on the build process? This is more a question on the process and less on the choice of automated build tools. Please share your build process. I would like to get an end-to-end view from developers checking-in to Going Live.

• Using a string as an object reference

  - by user317362

  I currently have a Javascript function that uses a string to reference an object name and acces its properties. I'm currently using eval() to get the the desired effect which I know is very, very wrong. Here is an example of how I'm currently achieving what I want: var stringToObjectRef = function() { var myTestVar = "myTestObject"; var myTestObject = { 'item1' : 100, 'item2' : 12, 'item4' : 18 }; var myValue = eval(myTestVar + '.item1'); alert(myValue); }(); I've tried using something like [myTestVar].item1, but this returns undefined. What is the correct syntax to achieve this? Thanks in advance.

• Create MVC 5 Combo Box from CRM Entities?

  I am working on an MVC 5 App that pulls data from Dynamics CRM 5. The Data I am getting back is an IQueryable of type Account (The CRM Entity class auto generated by CrmSvcUtil). I am retrieving all of the items and can loop through them with code like this: @foreach (var item in Model.ToList()) { <tr> <td> @item.AccountId </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> </tr> } The problem is, I would like to instead put them in a drop down list. I can't figure out what the syntax is to put these in a DropDown is. Any suggestions?

• Looking for a VIM Book

  - by sixtyfootersdude

  I have been using vim for about six months now. I know my way around pretty well. I know all of the "basic commands", have defined my own functions and have defined some syntax files. I was hopping to pickup a book on vim to read in my spare time. There is nothing specific that I want to learn I just want to improve my general knowledge. I looked on amazon and there are about 7 possibilities. Any recommendations?
