  • Designing Relational Survey Questionnaires Database

    - by user1213055
    I'm trying to build a simple sql database for following access database. Currently there is no relationship and I just have two tables male and female with 6 sections in each form. How can I design it a better way so end user can connect to the database and analyze using STATA or SPSS ? I'm really confused whether I should create one table with all fields or break down into different tables. The database is specific to this study only so I'm not looking for a generic survey database where user can create surveys and capture them. Any feedback or suggestion is much appreciated.

  • How would one call std::forward on all arguments in a variadic function?

    - by Noah Roberts
    I was just writing a generic object factory and using the boost preprocessor meta-library to make a variadic template (using 2010 and it doesn't support them). My function uses rval references and std::forward to do perfect forwarding and it got me thinking...when C++0X comes out and I had a standard compiler I would do this with real variadic templates. How though, would I call std::forward on the arguments? template < typename ... Params void f(Params ... params) // how do I say these are rvalue reference? { y(std::forward(...params)); //? - I doubt this would work. } Only way I can think of would require manual unpacking of ...params and I'm not quite there yet either. Is there a quicker syntax that would work?

  • Can somebody explain the difference between exceptions and errors (specific to PHP)?

    - by letseatfood
    I am having trouble figuring the best way to display errors to my clients. Should I use exceptions or errors? For example, if the user's login information does not match the database, should I throw new Exception('Login information is incorrect. Please try again.') and catch it with an exception handler using set_exception_handler()? Or, should I use trigger_error() to display an error message to the user? I think the main issue is that I cannot differentiate between errors and exceptions. I have read a lot of "answers" to this question on the internet and in some books, but it seems that people are really divided or aren't sure. Thanks!

  • Image not getting displayed on a JPanel.

    - by Myth17
    class Deal implements ActionListener { public void actionPerformed(ActionEvent e) { dl.setDeck(); dl.shuffle(); dl.firstDraw(pl); for(Card c:pl.showHand()) panelplay.add(new JLabel(c.getImageIcon())); panelplay.validate(); } } This is an event handler for a Jbutton. The method pl.showHand() returns a ArrayList of a user defined class 'Card'. Inserting a println() inside the loop shows the print, so the code is being executed but the Panel panelplay isnt showing card Images.

  • embedded wpf textbox does not accept input

    - by pro3carp3
    I put a wpf textbox inside a combobox to allow the user to enter a custom setting. I can read the keypress in the keydown event, but the text in the textbox does not change. What am I missing? <ComboBoxItem Name="GridSizeCustom"> <StackPanel Height="30" Orientation="Horizontal"> <TextBlock Text="Grid Size (8 - 200)" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0" /> <TextBox Name="GridSizeBox" KeyDown="test" Width="50" /> </StackPanel> </ComboBoxItem> I step through this event handler when I press a key, but no change to the textbox text: public void test(Object sender, KeyboardEventArgs e) { int x = 0; } Any help is appreciated. Thanks.

  • LINQ Expression help with Func TEntity,TType

    - by Chris Conway
    I have a repository method that accepts an order by parameter in the form: public IEnumerable<TEntity> Get<TEntity>(Expression<Func<TEntity,string>> orderBy) Now that works fine when trying to sort by a property of type string, var entities = rep.Get(x => x.Name); but what if i want to sort by double or int or any other type. Doing something like var entities = rep.Get(x => x.Price); obviously throws a compile error saying I can't convert double to string. How can I make this more generic so I can sort by any property in my entity, or at least the properties where the type implements IComparable or something similar?

  • How to get the next prefix in C++?

    - by Vicente Botet Escriba
    Given a sequence (for example a string "Xa"), I want to get the next prefix in order lexicographic (i.e "Xb"). As I don't want to reinvent the wheel, I'm wondering if there is any function in C++ STL or boost that can help to define this generic function easily? If not, do you think that this function can be useful? Notes The next of "aZ" should be "b". Even if the examples are strings, the function should work for any Sequence. The lexicographic order should be a template parameter of the function.

  • i have a arraylist where i am verifying particular object is existing or not but even it exists it always returns false

    - by Raghavender Reddy
    hi i have class called userdata which returns the Userarraylist which is of type User. when ever i try to use contains method to check particular property is existing or not it always returns false why? Actually i want the array list to be generic which should return the objects that are set in array list. String className = data.getUserData().get(0).getClass().getSimpleName(); if(className.equalsIgnoreCase("User")) { ArrayList<User> userdata=new ArrayList(); userdata = data.getUserData(); System.out.println(data.getUserData().contains(u.getUserId())); if(userdata.contains(u.getUserName())) { System.out.println(userdata.get(0).getEmailId()); } }

  • How do I identify where the POST data sent to a PHP script came from?

    - by Mike Turley
    I have a ton of data collection forms on my website, and I wrote a PHP script to handle all the data. All the forms have that one script as their action, and POST as the method. The handler emails a copy of the data to me, and I'd like for the emails I get to contain the URL of the form where they originated. Is there any way in PHP to get the url of the form which was submitted to the script? Or do I have to add an extra hidden field in every form with its URL?

Where´s the difference?

  • focusout not triggering when clicking on another selector with a click

    - by Sean
    I have 2 divs that each have clicks bound to them. when you click on a div a form is displayed (in another div) that allows you to set properties specific to the div that is clicked. I'm using focusout to save the properties to a data object. everything is working perfectly except when i click on the other div. it seems that the click handler on the other div cancels out the focusout of the form field. Has anyone else experienced this? is so what is the proper way to overcome this?

  • How to prevent inputting Russian characters in Word with a Word addin?

    - by Edwin
    Hi, Sorry for this vaguely described problem, but please look at the problem from the Win32 API's perspective. I'm writing a Word addin using Addin Express with Delphi, and I use some other 3rd party VCL's also, including virtual stringtree, TNT controls, etc. Now I cannot input Russian characters in Word anymore, but I can input English and Chinese.... Since it's a large project I don't know where to start finding the problem, would you give me some generic tips, I'll be appreciated that! Thank you, and have a nice day!

  • String Manipulation in Bash

    - by user348000
    Hello- I am a newbie in Bash and I am doing some string manipulation. I have the following file among other files in my directory: jdk-6u20-solaris-i586.sh I am doing the following to get jdk-6u20 in my script: myvar=`ls -la | awk '{print $9}' | egrep "i586" | cut -c1-8` echo $myvar but now I want to convert jdk-6u20 to jdk1.6.0_20. I can't seem to figure out how to do it. It must be as generic as possible. For example if I had jdk-6u25, I should be able to convert it at the same way to jdk1.6.0_25 so on and so forth Any suggestions?

  • How do develop a Java web application without having to deploy all the time

    - by ChrisSmith..zzZZ
    I've set up a simple Eclipse 3.5/Jetty 6.1 web app which returns hello world. It works. This is on Windows and uses the "Jetty Generic Server Adapter". I have auto deployment working so that it deploys after changes periodically. How do I go about setting it up so that if I change any static content it doesn't have to redeploy i.e I can just hit F5 to see the changes straight away. For minor HTML changes it's quite unusable waiting 20-30 seconds for a deployment.

  • Java using enum with switch statement

    - by MisterSquonk
    I've looked at various Q&As on SO similar to this question but haven't found a solution. What I have is an enum which represents different ways to view a TV Guide... static enum guideView { GUIDE_VIEW_SEVEN_DAY, GUIDE_VIEW_NOW_SHOWING, GUIDE_VIEW_ALL_TIMESLOTS } ...when the user changes the view an event handler receives an int from 0-2 and I'd like to do something like this... // 'which' is an int from 0-2 switch (which) { case NDroid.guideView.GUIDE_VIEW_SEVEN_DAY: ... break; } I'm used to C# enums and select/case statements which would allow something like the above and I know Java does things differently but I just can't make sense of what I need to do. Am I going to have to resort to if statements? There will likely only ever be 3 choices so I could do it but I wondered how it could be done with switch-case in Java.

  • Why can I check some event handlers for null, some not?

    - by Inno
    Hi, I have a ugly piece of code that adds event handlers. The problem is, if the code is called multiple times, the event handlers are called multiple times. To solve the problem, I remove the event handler first and then add it. Now I've seen the following behaviour: Some event handlers can be checked like: if (object.event == null) { // // Code // } others of the form if (object.object.event == null) { // // Code // } I get a message like 'object.object.event' may only occur left of -= or +=. (Since I'm using a german version of visual studio, I don't know the correct translation to english). I have no idea why the behaviour looks this inconsequent so I would be grateful for some information on this. To be more specific: It's user control. if (myControl.Event == null) { // // works // } if (myControl.TreeView.NodeMouseClick == null) { // // doesn't work // }

  • Jquery adding events

    - by JBone
    I want to add an event handler to some dynamically added elements. I simplified my problem into the basic code below. I am using the new JQuery 1.7 on feature to say "hey for all labels in the CancelSurvey id element call this notify function when they are clicked." function notify(event) { console.log(event.data.name); } $('#CancelSurvey').on('click', 'label', { name: $(this).attr("id") }, notify); I want to pass the id of the label as parameter "name". When I try to alert this it is undefined (they are defined in the html created). I believe that using the $(this) is not referencing the label selector in this case. It actually seems to be referencing the document itself. Any ideas on how to accomplish this?

  • Why Enumerable doesn't inherits from IEnumerable<T>

    - by sajjadlove
    Hi All I'm very confused about this issue and can't to underestand it.In the Enumerable Documentation, I readed this: that implement System.Collections.Generic.IEnumerable and some methods like Select() return IEnumerable that we can use from other methods like Where() after using that.for example: names.Select(name => name).Where(name => name.Length > 3 ); but Enumerable doesn't inherits from IEnumerable and IEnumerable doesn't contain Select(),Where() and etc too... have i wrong ? or exists any reason for this?

  • Can a variable like 'int' be considered a primitive/fundamental data structure?

    - by Ravi Gupta
    A rough definition of a data structure is that it allows you to store data and apply a set of operations on that data while preserving consistency of data before and after the operation. However some people insist that a primitive variable like 'int' can also be considered as a data structure. I get that part where it allows you to store data but I guess the operation part is missing. Primitive variables don't have operations attached to them. So I feel that unless you have a set of operations defined and attached to it you cannot call it a data structure. 'int' doesn't have any operation attached to it, it can be operated upon with a set of generic operators. Please advise if I got something wrong here.

  • What is the sense of "Feature Oriented Programming" (FOP) in C++, and would it make sense in Java an

    - by ivan_ivanovich_ivanoff
    Hello! Sadly, I can't remember where I read it, but... ...in C++ you can derive a class from a template parameter. Im pretty sure it was called Feature Oriented Programming (FOP) and meant to be somehow useful. It was something like: template <class T> class my_class : T { // some very useful stuff goes here ;) } My questions about this: What is the sense of such pattern? Since this it not possible in Java / C#, how this pattern is achieved in these languages? Can it be expected to be implemented in Java / C# one day? (Well, first Java would need to get rid of type erasure) EDIT: I'm really not talking about generics in Java / C# (where you can't derive a class from a generic type parameter)

  • Handling a binary operation that makes sense only for part of a hierarchy.

    - by usersmarvin_
    I have a hierarchy, which I'll simplify greatly, of implementations of interface Value. Assume that I have two implementations, NumberValue, and StringValue. There is an average operation which only makes sense for NumberValue, with the signature NumberValue average(NumberValue numberValue){ ... } At some point after creating such variables and using them in various collections, I need to average a collection which I know is only of type NumberValue, there are three possible ways of doing this I think: Very complicated generic signatures which preserve the type info in compile time (what I'm doing now, and results in hard to maintain code) Moving the operation to the Value level, and: throwing an unsupportedOperationException for StringValue, and casting for NumberValue. Casting at the point where I know for sure that I have a NumberValue, using slightly less complicated generics to insure this. Does anybody have any better ideas, or a recommendation on oop best practices?

  • How to raise an event when another event is raised?

    - by WulfgarPro
    Hi, I have an application that handles the OnQuit event of another running application. I would like to raise an additional (custom) event when the OnQuit event is handled. How could I implement such an event? My OnQuit handler is like so: private void StkQuit() { _stkApplicationUi.OnQuit -= StkQuit; Marshal.FinalReleaseComObject(_stkApplicationUi); Application.Exit(); } The reason I require the additional event is so that I can tell my View layer that the application has exited. If this is not the correct way, what would be better? WulfgarPro

  • how to make complex selectors with 'this' jquery

    - by Stomped
    I have an event handler that needs to do something to one of its children, based on some saved data. So what I'm currently doing is something like this: // Get the ID of 'this' item_id = $(this).attr('id'); // building a selector like $('#item1 .child_3') $('#' + item_id + ' .child_' + spVal).addClass('blah'); But this seems a little cumbersome. I've tried: $(this + ' .child_' + spVal).addClass('blah'); and it doesn't work, which doesn't really surprise me. Is there a better way to do this then the successful way I've outlined above?
