  • 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?

  • Is it possible to supply template parameters when calling operator()?

    - by Paul
    I'd like to use a template operator() but am not sure if it's possible. Here is a simple test case that won't compile. Is there something wrong with my syntax, or is this simply not possible? struct A { template<typename T> void f() { } template<typename T> void operator()() { } }; int main() { A a; a.f<int>(); // This compiles. a.operator()<int>(); // This compiles. a<int>(); // This won't compile. return 0; }

  • How to check null element if it is integer array in Java?

    - by masato-san
    I'm quite new to Java and having an issue checking null element in integer array. I'm using Eclipse for editor and the line that checks null element is showing error: Line that complains: if(a[i] != null) { Error msg from Eclipse: The operator != is undefined for the argument type(s) int, null In PHP, this works without any problem but in Java it seems like I have to change the array type from integer to Object to make the line not complain (like below) Object[] a = new Object[3]; So my question is if I still want to declare as integer array and still want to check null, what is the syntax for it? Code: public void test() { int[] a = new int[3]; for(int i=0; i<a.length; i++) { if(a[i] != null) { //this line complains... System.out.println('null!'); } } }

  • 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.

  • jquery animate() problem

    - by meo
    $('#somediv').stop(false, true).animate({marginLeft: '-=' + e.width() + 'px'}, options.speed, function(){ options.onNewSlide() }) e.with() returns 640 opctions.speed contains 800 options.onNewSlide() contains a a custom callback function It works fine in firefox. But i debugged it with jquery.lint because it was throwing some random error in IE. lint tells me: When I called animate(...) with your args, an error was thrown! TypeError: c.speed is not a function { message="c.speed is not a function", more...} You passed: [Object { marginLeft="-=640px"}, 800, function()] and it indicates me the line i have posted. I have checked the jquery doc, but my syntax seams ok. Do you know what i am doing wrong?

  • Wordpress php: Way to test if pages are children of a parent page?

    - by Erykan
    Hi - Working on my first Wordpress site so I'm sure this is a really basic question. I'm struggling to write a conditional php statement that performs a certain action when a page is a child of a parent page. For example, rather than just specifying one page, as below, I'd like to specify all pages that have the 'About Us' page as a parent: <?php if (is_page('About Us')) echo 'Hello World!'; ?> I've tried the "child_of" function but it wasn't as straightforward as I'd hoped. When I use the below, I get a syntax error - probably just me not knowing how to use the function: <?php if (child_of('About Us')) echo 'Hello World!'; ?> Any suggestions? Thanks!!

  • Create MVC 5 Combo Box from CRM Entities?

    - by SpaceCowboy74
    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?

  • 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!

  • Looking for a way to highlight specific words in textareas?

    - by Dan
    Hi i'm looking for a way to highlight specific words in text kind of like how a text editor might work with syntax highlighting. The highlighting will consist of the text being different colours and/or different styles such as italic, bold or regular. In order to narrow focus, how this might be achieved using Java Swing components. There are most probably a number of ways of doing this but one that is efficient in dealing with multiple highlighted words and large amounts of text. Any feedback is appreciated. Thanks.

  • Generic SQL builder .NET

    - by Patrick
    I'm looking for a way to write an SQL statement in C# targeting different providers. A typical example of SQL statements differentiating is the LIMIT in PostgreSQL vs. TOP in MSSQL. Is the only way to solve SQL-syntax like the two above to write if-statements depending on which provider the user selects or using try catch statements as flow control (LIMIT didn't work, I'll try TOP instead)? I've seen the LINQ Take method, but I'm wondering if one can do this without LINQ? In other words, does C# have some generic SQL Provider class that I have failed to find that can be used?

  • C# Generics Multiple Inheritance Problem

    - by Ciemnl
    Can any one help me with this syntax issue with C#? I have no idea how to do it. class SomeClass<T> : SomeOtherClass<T> where T : ISomeInterface , IAnotherInterface { ... } I want SomeClass to inherit from SomeOtherClass and IAnotherInterface and for T to inherit ISomeInterface only It seems the problem is that the where keyword screws everything up so that the compiler thinks both ISomeInterface and IAnotherInterface should both be inherited by T. This problem is very annoying and I think the solution is some kind of parenthesis but I have tried and failed finding one that works. Also, switching around the order of the two items inherited from SomeClass does not work because the class inherited always has to come before any interfaces. I couldn't find any solutions on the MSDN C# generics pages and I can't beleive I'm the first person to have this problem. Thanks, any help is much appreciated!

  • Preventing SQL injecting in a database class

    - by Josh
    I'm building a database class and thought it'd be a good idea to incorporate some form of SQL injection prevention (duh!). Here's the method that runs a database query: class DB { var $db_host = 'localhost'; var $db_user = 'root'; var $db_passwd = ''; var $db_name = 'whatever'; function query($sql) { $this->result = mysql_query($sql, $this->link); if(!$this->result) { $this->error(mysql_error()); } else { return $this->result; } } } There's more in the class than that but I'm cutting it down just for this. The problem I'm facing is if I just use mysql_real_escape_string($sql, $this->link); then it escapes the entire query and leads to a SQL syntax error. How can I dynamically find the variables that need to be escaped? I want to avoid using mysql_real_escape_string() in my main code blocks, i'd rather have it in a function. Thanks.

  • Lambda expression will not compile

    - by John Soer
    I am very confused. I have this lamba expression: tvPatientPrecriptionsEntities.Sort((p1, p2) => p1.MedicationStartDate .Value .CompareTo(p2.MedicationStartDate.Value)); Visual Studio will not compile it and complains about syntax. I converted the lamba expression to an anonymous delegate as so: tvPatientPrecriptionsEntities.Sort( delegate(PatientPrecriptionsEntity p1, PatientPrecriptionsEntity p2) { return p1.MedicationStartDate .Value .CompareTo(p2.MedicationStartDate.Value); }); and it works fine. The project uses .NET 3.5 and I have a reference to System.Linq.

  • C# method contents validation

    - by user258651
    I need to validate the contents of a C# method. I do not care about syntax errors that do not affect the method's scope. I do care about characters that will invalidate parsing of the rest of the code. For example: method() { /* valid comment */ /* <-- bad for (i..) { } for (i..) { <-- bad } I need to validate/fix any non-paired characters. This includeds /* */, { }, and maybe others. How should I go about this? My first thought was Regex, but that clearly isn't going to get the job done.

  • Codeigniter: Using data in a controller

    - by Kevin Brown
    I'm new to php and CI, and I'm having some trouble in my controller. I feel that I'm doing this the wrong way, and it could be easier, I just don't know the syntax: $data['members'] = $this->home_model->getUser($id); $credit = $this->home_model->getCredit($id); if ($credit == '0'){stuff...} So I'm getting the user's data that has their the same information as "getCredit" does, but I don't know how to get the single variable that I need for my if statement... How can I just use the "getUser" function so that I'm not pulling redundant information?

  • Make SQL query more efficient

    - by Webnet
    I currently have this query which runs 2 of the exact same sub queries but pull different data. When I make the values comma separated it throws an SQL error saying the sub query can return only one value. Is there anything else I can do to avoid running multiple sub queries? SELECT product_id, ( SELECT COUNT(listing_id) FROM ebay_archive_product_listing_assoc WHERE product_id = product_master.product_id) as listing_count, sku, type_id, ( SELECT AVG(ebay_archive_listing.current_price), AVG(ebay_archive_listing.buy_it_now_price) FROM ebay_archive_listing WHERE id IN ( SELECT listing_id FROM ebay_archive_product_listing_assoc WHERE product_id = product_master.product_id ) AND ebay_archive_listing.start_time >= '.$startTimestamp.' AND ebay_archive_listing.start_time <= '.$endTimestamp.' AND ebay_archive_listing.current_price > 0 ) as average_bid_price, ( SELECT FROM ebay_archive_listing WHERE id IN ( SELECT listing_id FROM ebay_archive_product_listing_assoc WHERE product_id = product_master.product_id ) AND ebay_archive_listing.start_time >= '.$startTimestamp.' AND ebay_archive_listing.start_time <= '.$endTimestamp.' AND ebay_archive_listing.buy_it_now_price > 0 ) as average_buyout_price FROM product_master I'm aware of the syntax error... I'm selecting 2 seperate averages and am wondering if I can do it any simpler way.

  • Good JDBC pattern

    - by Java Developer
    What is the good practice for database operation in Java application? Do you construct the DML syntax in the Java code and send the statements to DB engine for execution, or you just collect the parameters and then make a call to stored procedure with the parameters via java code? or neither because that's just not how to do it? can anyone give an example of a full database utility classes to do database operations in Java app? also what about the transaction manager? My assignment is to make database operation that is modular in Java. Thanks

  • Rails Scope for association of 0 size.

    - by MissingHandle
    I'm having trouble figuring out the scope method for all the Foos that have no Bars. That is: class Foo < ActiveRecord::Base has_may :bars end class Bar < ActiveRecord::Base belongs_to :foo end I'd like to write a scope method that returns me all the foos that have no bars. Something like: class Foo < ActiveRecord::Base has_may :bars scope :has_no_bars, includes(:bars).where("COUNT(foo.bars) = 0") end But I don't understand the appropriate syntax. Any help? Happy to use a MetaWhere solution if easier.

  • Why does this Bash regex match return an Exit Status of "2"?

    - by PreservedMoose
    I'm writing a Bash script that needs to scan for the existence of non-ASCII characters in filenames. I'm using the POSIX bracket regex syntax to match the non-ASCII characters, but for some reason, when I test for the match in an if/then statement, the test always returns an Exit Status of 2, and never matches my test string. Here's the code in question: FILEREQ_SOURCEFILE="Filename–WithNonAScII-Charàcters-05sec_23.98.mov" REGEX_MATCH_NONASCII="[^[:ascii:]]" if [[ $FILEREQ_SOURCEFILE =~ $REGEX_MATCH_NONASCII ]]; then echo "Exit Status: $?" echo "Matched!" else echo "Exit Status: $?" echo "No Match" fi This code always returns: Exit Status: 2 No Match I've read and re-read the bash-hackers.org explanation of how regex matching works, as well as this previous question on SO regarding matching non-ASCII characters, but for the life of me, I can't get this to work. What am I missing here?

  • can't compile min_element in c++

Please, help!

  • Approach to Selecting top item matching a criteria

    - by jkelley
    I have a SQL problem that I've come up against routinely, and normally just solved w/ a nested query. I'm hoping someone can suggest a more elegant solution. It often happens that I need to select a result set for a user, conditioned upon it being the most recent, or the most sizeable or whatever. For example: Their complete list of pages created, but I only want the most recent name they applied to a page. It so happens that the database contains many entries for each page, and only the most recent one is desired. I've been using a nested select like: SELECT pg.customName, pg.id FROM ( select id, max(createdAt) as mostRecent from pages where userId = @UserId GROUP BY id ) as MostRecentPages JOIN pages pg ON pg.id = MostRecentPages.id AND pg.createdAt = MostRecentPages.mostRecent Is there a better syntax to perform this selection?

  • use printf("text %d", number) type format to assign value to variable

    - by rksprst
    I would like to use the syntax that printf uses, using the %d, %s and adding values after to assign a value to a char[]. Is this possible? e.g. Given an output of: printf("now: %d-%d-%d %d:%d:%d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec); I'd like to assign that to char[] output; How can this be done? I tried: sprintf(output, "now: %d-%d-%d %d:%d:%d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec); but that didn't seem to work. Is sprintf used differently... or is that not what I should be using? Thanks!

  • why does the data property in an jquery ajax call override my return false?

    - by user315709
    hi, i have the following block of code: $("#contact_container form, #contact_details form").live( "submit", function(event) { $.ajax({ type: this.method, url: this.action, data: this.serialize(), success: function(data) { data = $(data).find("#content"); $("#contact_details").html(data); }, }); return false; } ; when i leave out the data: this.serialize(), it behaves properly and displays the response within the #contact_details div. however, when i leave it in, it submits the form, causing the page to navigate away. why does the presence of the data attribute negates the return false? (probably due to a bug that i can't spot...) also, is the syntax to my find statement correct? it comes back as "undefined" even though i use a debugger to check the ajax response and that id does exists. thanks, steve
