• Adding a javascript immediate after body tag

  - by prabdrup

  I am making a drupal module. My requirement in the module is that when the module is activated then it needs to add a javascript in page.tpl file just after the body tag. Can anyone help me how to do this. I have tried using drupal_add_js but it will not exactly put the script after body tag, rather puts inside the head or below in footer. I also tried using template variable and preprocess method but the problem is the preprocess method replaces the old value of that variable with the new one. Is there a way how i can implement this in.

• json call with C#

  - by Vaccano

  I am trying to make a json call using C#. I made a stab at creating a call, but it did not work: public bool SendAnSMSMessage(string message) { HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://api.pennysms.com/jsonrpc"); request.Method = "POST"; request.ContentType = "application/json"; string json = "{ \"method\": \"send\", "+ " \"params\": [ "+ " \"IPutAGuidHere\", "+ " \"[email protected]\", "+ " \"MyTenDigitNumberWasHere\", "+ " \""+message+"\" " + " ] "+ "}"; StreamWriter writer = new StreamWriter(request.GetRequestStream()); writer.Write(json); writer.Close(); return true; } Any advice on how to make this work would be appreciated.

• C++ enforce conditions on inherited classes

  - by user231536

  I would like to define an abstract base class X and enforce the following: a) every concrete class Y that inherits from X define a constructor Y(int x) b) it should be possible to test whether two Y objects are equal. For a, one not very good solution is to put a pure virtual fromInt method in X which concrete class will have to define. But I cannot enforce construction. For b), I cannot seem to use a pure virtual method in X bool operator == (const X& other) const =0; because in overridden classes this remains undefined. It is not enough to define bool operator == (const Y& other) const { //stuff} because the types don't match. How do I solve these problems?

• Troubles with NSString writeToFile

  - by Jesse

  Hi everyone, I have been working on a simple text editor in Cocoa/Objective-C for a practice project and I have come across an error that I would never have expected. I have an NSString for my file's contents as well as an NSString for it's path. When I attempt to write the contents to a file, I use the following method: [FileContents writeToFile: CurrentFileName atomically: NO encoding: NSStringEncoding error: nil]; I've used this method many times without error yet today, I am getting an error: "Expected expression before 'NSStringEncoding'" If anyone can help me out with this it would be greatly appreciated. I can't figure out what could be causing the error. Thanks a lot!

• Forcing Reload of View when returning from FlipSideView of Utility Application

  - by Chris McCall

  I've got a Utility Application for iPhone 3.1.3. I have my main view loading fine. I flip over to the flipside view of the utility app and change some settings. How can I call the code I've currently got in viewDidLoad in the main view to refresh it, as settings have changed? Do I create a public method and call it from the viewDidUnload method of the flipside view? Do I call viewDidLoad directly? What's the best way to do this?

• How to yield a single element from for loop in scala?

  - by Julio Faerman

  Much like this question: Functional code for looping with early exit Say the code is def findFirst[T](objects: List[T]):T = { for (obj <- objects) { if (expensiveFunc(obj) != null) return /*???*/ Some(obj) } None } How to yield a single element from a for loop like this in scala? I do not want to use find, as proposed in the original question, i am curious about if and how it could be implemented using the for loop. * UPDATE * First, thanks for all the comments, but i guess i was not clear in the question. I am shooting for something like this: val seven = for { x <- 1 to 10 if x == 7 } return x And that does not compile. The two errors are: - return outside method definition - method main has return statement; needs result type I know find() would be better in this case, i am just learning and exploring the language. And in a more complex case with several iterators, i think finding with for can actually be usefull. Thanks commenters, i'll start a bounty to make up for the bad posing of the question :)

• Objective C memory management question with NSArray

  - by Robert

  I am loading an array with floats like this: NSArray *arr= [NSArray arrayWithObjects: [NSNumber numberWithFloat:1.9], [NSNumber numberWithFloat:1.7], [NSNumber numberWithFloat:1.6], [NSNumber numberWithFloat:1.9],nil]; Now I know this is the correct way of doing it, however I am confused by the retail counts. Each Object is created by the [NSNumber numberWithFloat:] method. This gives the object a retain count of 1 dosnt it? - otherwise the object would be reclaimed The arrayWithObjects: method sends a retain message to each object. This means each object has a retain cont of 2. When the array is de-allocated each object is released leaving them with a retain count of 1. What have I missed?

• question on find value in array

  - by davit-datuashvili

  i have seen a few days ago such problem there is given two array find elements which are common of these array one of the solution was sort big array and then use binary search algorithm and also there is another algorithm- brute-force algorithm for (int i=0;i<array1.length;i++){ for (int j=0;j<array2.length;j++){ if (array1[i]==array2[j]){ //code here } } it's complexity is O(array1.length*array2.length); and i am interested the first method's complexity is also same yes? because we should sort array first and then use search method binary search algorithm's complexity is log_2(n) so it means that total time will be array.length*log_2(n) and about sort? please explain me which is better

• How to get an array of all controllers in a Codeigniter project ?

  - by ashmckenzie

  I'd like to obtain a list of all controllers in a Codeiginiter project so I can easily loop through each of them and add defined routes. I can't seem to find a method that will give me what I'm after ? Here is the code snippet from the routes.php file where I would like to access the array: - // I'd like $controllers to be dynamically populated by a method // $controllers = array('pages', 'users'); // Loop through each controller and add controller/action routes // foreach ($controllers as $controller) { $route[$controller] = $controller . '/index'; $route[$controller . '/(.+)'] = $controller . '/$1'; } // Any URL that doesn't have a / in it should be tried as an action against // the pages controller // $route['([^\/]+)$'] = 'pages/$1';

  Hey Everyone, I am receiving this error: Requires a valid user is specified (either via the session or via the API parameter for specifying the user. when I am trying to utilize Facebook's FB.api with JS SDK for method: users.hasAppPermission I am constantly receiving this error, for any uid I pass on.

• Why is it possible to save entity but not delete if transactional annotation is set to readonly=true

  - by jakob

  Hello experts! My class is annotated with org.springframework.transaction.annotation.Transactional like this: @Transactional(readOnly = true) public class MyClass { I then have a dao class: @Override public void delete(final E entity) { getSession().delete(entity); } @Override public void save(final E entity) { getSession().saveOrUpdate(entity); } Then I have two methods in MyClass @Transactional(readOnly = false) public void doDelete(Entity entity){ daoImpl.delete(entity) } //@Transactional(readOnly = false) public void doSave(){ daoImpl.save(entity) } Saving and deleting works like a charm. But if I remove the @Transactional(readOnly = false) on doDelete method deletion stops working, Saving works with and without the method annotation. So my question is: WHY?

• What is the difference between these two ways of creating NSStrings?

  - by adame

  NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

• How to remove strings of certain lengths

  - by Macosx Iam

  So I have this array, and I want to delete strings that are 2 or 4 characters in length (strings that contain 2 or 4 characters). I am doing this method, and it doesn't work, even though logically, it SHOULD work. public static void main(String[] args) { ArrayList<String> list = new ArrayList<String>(); list.add("This"); list.add("is"); list.add("a"); list.add("test"); for (int i=0; i<list.size(); i++) { if(list.get(i).length()==2 || list.get(i).length()==4) { list.remove(i); } } } I'd like to stick to this method of doing it. Can you please give me some suggestions as to how to correct this code? The output of this code when I run it is: [is, a] Even though I want the output to be [a] because "is" is 2 characters long.

• Is there a Javadoc-like plugin for Xcode that automatically generates the doc template?

  - by Mark

  I'm aware of Doxygen to generate the documentation. What I'm looking for is quick way to insert documentation in Xcode similar to what Eclipse does when editing Java files. Let's say I have an objective-c method with a couple of arguments like this: -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {... In Eclipse, if you place the cursor above the method and type: /**<Enter> you get a Javadoc template pre-populated with @param and @return tags. Is it possible to achieve something similar in Xcode? After typing /**<Enter>, I'd like to get this automatically: /** * * @param one * @param two * * @return */ -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {...

• Methods specific only to an instance? What are they called in Ruby?

  - by daremarkovic

  I know there are "instance methods", "class methods" but what are these types of methods called, for eg: s1 = "This is my STRING!" def s1.m1 downcase end p s1 # => "This is my STRING!" p s1.m1 # => "this is my string!" What type of method is the "m1" method called on the s1 "instance" of the "string" class? It's really weird because I didn't know this was possible at all if I try: s2 = "This is ANOTHER string" s2.m1 # => Won't work! Which kind of makes sense, but not sure why defining methods like m1 on instances on a class are useful at all.

• Problem with jQuery animation

  - by Daemon

  I have a problem with an animation in jQuery using ajax. On the click of an button (actually an tag), I call a ajax method, and have the following written inside the success parameter: success: function(msg) { $('.ContentsMainRight').children().fadeOut(500, function() { $('.ContentsMainRight').html(msg.d); $('.ContentsMainRight').children().fadeIn(1000); }); }, This have the following result. The contents of a div fade out over 500ms as it's supposed to. Then the html contents of the div are swapped, but then the last part did not work as I hoped. The html returned by the ajax method include some text inside a tag, and a image inside a tag. The result is that the text is automatically displayed instantly with no fadein, but the img that is put fades in over 1 second. Why is the text and image treated differently? -Daemon

• Refactoring a nested loop

  - by user3517441

  I have the following code which I use a lot of times in the class. for (int i = 0; i < someList.size(); i++) { for (int j = 0; j < someList.size(); j++) { if (i != j) { someList.get(i).sendMessageTo(someList.get(j))); //variable action } } } The purpose of the loop is to make each element in the List to send a message (or perform another action) to every element in the list except itself. Is there any way I can create a helper method so I don't have to repeat the loop code. I want to be able to state the variable action and call the helper method. Thanks.

• How to secure an API written in .Net

  - by The Diamond Z

  This is a variation on an existing question in SO about securing/obfuscating .Net applications in general. I'm developing an API in C# that includes some algorithms I'm keen to protect. I understand no method will be perfect, but what's the generally accepted method for doing this? I'd like my clients to be able to code against the API but I don't want them to reverse engineer what's inside (at least I don't want to make it easy for them). If I obfuscate the code, won't that also obfuscate the API? We're looking at smartAssembly any thoughts comments on the product would be appreciated.
