• What types of conditions can be used for conditional compilation in C++?

  - by user1002288

  This is an exam question for C++: Which of the following statements accurately describe the condition that can be used for conditional compilation in C++? A. The condition can depend on the value of environment variables. B. The condition can depend on the value of any const variables. C. The condition can depend on the value of program variables. D. The condition can use the sizeof() operator to make decision about compiler-dependent operations based on the size of standard data type. E. The condition must evaluate to either a 0 or 1 during preprocessing. I think the answer is E. Is this correct?

• PHP strtotime() setting date to default

  - by Paddyd

  I have a script which is reading values from an excel sheet and inserting them into an sql table. My problem is when the script reads in some of the date fields it is setting them to a default value : 1970-01-01 01:00:00 I have noticed that this is happening when it comes across a date where the 'day' is greater than 12 : 13/05/2012 18:52:33 (dd-mm-yyyy hh-mm-ss) I thought this may be due to the script thinking that this is the month field (i.e american format) and it sees it as an invalid value, so I set the default timezone to my own hoping it may resolve the problem but it made no difference. date_default_timezone_set('Europe/Dublin'); Here is an example of what my code is doing: Excel field value : 01/05/2012 18:32:45 Script: $start_time = $data->val($x,5); echo $start_time = date("Y-m-d H:i:s", strtotime($start_time)); Output: 2012-01-05 18:32:45 This is the exact format I am looking for (except for the fact that the day and month fields are switched around i.e american date format) but it doesnt work for the type of dates I mentioned above.

• How is this relation in 4th normal form? Is the dependency trivial?

  - by squ

  I have a question that concerns multi value dependency. The relation looks like this: R(A,B) with A -->> B (A multi value determines B) I've been told that this relation is in 4th normal form, but I don't really se how. I know that if the multi value dependency is trivial, then it doesn't violate the 4th normal form. But is this trivial? It would be trivial if it, for example, looked like this: {A,B} -->> B But the first dependency example shouldn't be trivial. The other rule for 4th NF says that A in this case needs to be a super key of the relation, but it isn't. As far as I can tell, A isn't a super key, since {A,B} is needed to identify a tuple. So the question is, why is this in 4th normal form? It seems to be violating both of the rules.

• How to do a random-and-unique generator?

  - by javaLearner.java

  I already wrote a random generator which take arguments a and b, where a is minimun and b is maximum value, like this randomGenerator(int a, int b) What I want to do next is: Using a loop, then generate unique number from a to b. Example: I want to have 8 unique numbers, int a = 1; int b = 10; int value; If I do the loop, there is a high % that same number will appear more than once. Any idea how to do it? My own way is: while(int i <= 8){ randomGenerator(a,b); // if value is not in array, then insert into array } I am stuck at the comment part. Is there any way to check if a variable is exists in an array?

• How to count number of occurences for all different values in database column?

  - by drasto

  I have a Postgre database that has say 10 columns. The fifth column is called column5. There are 100 rows in the database and possible values of column5 are c5value1, c5value2, c5value3...c5value29, c5value30. I would like to print out a table that shows how many times each value occurs. So the table would look like this: Value(of column5) number of occurrences of the value c5value1 1 c5value2 5 c5value3 3 c5value4 9 c5value5 1 c5value6 1 . . . . . . What is the command that does that? Thanks for help

• Oracle Reports SELECT INTO Not Selecting

  - by Kevin Cruz

  I'm working on a Report in Oracle Reports Builder, and having issues with my AFTERPFORM trigger. When viewing the report, it seems like the year is being processed properly, while the period and subperiod are using their initial values. I'm confused because they are the exact same select statement, but are not working as intended. Any help would be greatly appreciated! function AfterPForm return boolean is v_subpdenddt_user date; v_subpdenddt_max date; v_rowcount integer; begin select value into year from wos_report_param where parameter = 'year' and sequence_num = :sequencenum; select value into period from wos_report_param where parameter = 'period' and sequence_num = :sequencenum; select value into user_subpd from wos_report_param where parameter = 'subpd' and sequence_num = :sequencenum;

• Why the data binding in this validation example works in WPF?

  - by MartyIX

  I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

• [JQuery] Edit Css with animation effect

  - by Pennywise83

  Hi, I've a div in a absolute position with a default "top" value set to "-200px". When i click on the div the "top" value is updated to "0". In this way I see the entire Div. This is the js: $(document).ready(function(){ $("#search_bar").click(function () { $(this).css("top","0"); }); }); Is there a way to achieve this result but with an animation? For example, a slide down effect? Also, when i click another time to the div I'd like that the "top" value will be restored to "-200px".

• Pattern matching against Scala Map type

  - by Tom Morris

  Imagine I have a Map[String, String] in Scala. I want to match against the full set of key–value pairings in the map. Something like this ought to be possible val record = Map("amenity" -> "restaurant", "cuisine" -> "chinese", "name" -> "Golden Palace") record match { case Map("amenity" -> "restaurant", "cuisine" -> "chinese") => "a Chinese restaurant" case Map("amenity" -> "restaurant", "cuisine" -> "italian") => "an Italian restaurant" case Map("amenity" -> "restaurant") => "some other restaurant" case _ => "something else entirely" } The compiler complains thulsy: error: value Map is not a case class constructor, nor does it have an unapply/unapplySeq method What currently is the best way to pattern match for key–value combinations in a Map?

• How can i get the selected option name or id of a select element using jQuery

  - by bill

  Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.

• Problem with onsubmit ID

  - by Liso22

• Access shell methods in controller? Cake PHP 1.3

  - by anonymous coward

  I wrote a shell method in CakePHP 1.3 that has a return value. I'd like to be able to access that method from within a controller, so that I can pass its return value into the View. I'm not sure how to access those methods appropriately from within the controller. Have I done it wrong? I could easily duplicate the code, but I'd like to "keep it DRY", and the actual functionality, I believe, doesn't belong with this particular controller - I just need it's return value in this particular view.

• What do C# Table Adapters actually return?

  - by Raven Dreamer

  I'm working on an application that manipulates SQL tables in a windows form application. Up until now, I've only been using the pre-generated Fill queries, and self-made update and delete queries (which return nothing). I am interested in storing the value of a single value from a single column (an 'nchar(15)' name), and though I have easily written the SQL code to return that value to the application, I have no idea what it will be returned as. SELECT [Contact First Name] FROM ContactSkillSet WHERE [Contact ID] = @CurrentID Can the result be stored directly as a string? Do I need to cast it? Invoke a toString method?

• MYSQL sum() for distinct rows

  - by makeee

  I'm looking for help using sum() in my SQL query (not posting full query since the scenario is fairly simple). I have COUNT(DISTINCT conversions.id) in my query. I use DISTINCT because I'm doing "group by" for multiple columns and this ensures the same row is not counted more than once. Now I want to add: SUM(conversions.value) as conversion_value The problem is that the "value" for each row is counted more than once (due to the multiple group bys) I basically want to do SUM(conversions.value) for each DISTINCT conversions.id. Is that possible?

• Can the Browser 'Forward' Button be Set from HTML?

  - by John C

  Example: At the bottom of the StackOver Questions page are a bunch of page numbers (1,2,3...), enclosed in a set of prev and next buttons. Clicking next repeatedly will bring me to, say page 5, at which point I will have: The page's prev button will be set to 'http://stackoverflow.com/questions?page=4' The Back button on my Browser will have the same value. The page's next button will be set to 'http://stackoverflow.com/questions?page=6' The Forward button on my Browser - won't be set to anything. Obviously, if I hit the Back button on the Browser, then Forward will have a value, pointing to the URL for page 5 - but not otherwise. Is there any way, from HTML (plus Javascript), to set the value of the Browser's Forward button? Or is this one of those things that HTML is simply forbidden to do?

• Calling inheriting class methods via interface.

  - by Stacey

  Given the scenario... interface IBase{ void Process(int value); } abstract class Base : IBase { public virtual void Process(int value){ throw new NotImplementedException(); } } class Implemented: Base, IBase { public void Process(int value) { // .. some code here.. } } I'm trying to write a loop similar to the following. foreach( Base b in CollectionOfImplemented ) { b.Process( // something will go here // ); } Trying this, it keeps calling Base.Process, instead of Implemented.Process; but the type in the collection is Implemented, not Base. Boxing it seems to work, but I was hoping to see if I could find a more intelligent approach to it, since the Collection will contain other types of objects that also inherit from Base.
