Examples of the translations I need to do: $stringDate = "November 2009"; $output = "11/09"; $stringDate = "October 1 2010"; $output = "10/01/2010"; $stringDate = "January 2010"; $output = "01/10"; $stringDate = "January 9 2010"; $output = "01/09/2010"; Note that I do not know which format the $stringDate will be in and the lack of commas in the month day year set.

Is object clearing/array deallocation really necessary in VB6/VBA (Pros/Cons?)
- by Oorang
Hello, A lot of what I have learned about VB I learned from using Static Code Analysis (Particularly Aivosto's Project Analyzer). And one one of things it checks for is whether or not you cleared all objects and arrays. I used to just do this blindly because PA said so. But now that I know a little bit more about the way VB releases resources, it seems to me that these things should be happening automatically. Is this a legacy feature from pre VB6, or is there a reason why you should explicitly set objects back to nothing and use Erase on arrays?Read the article

Is there a method I can override on a JavaScript object to control what is displayed by console.log?
- by agnoster
I'm thinking in particular of Chrome, though Firebug would be interesting to. I've tried toString() and valueOf(), but neither of those seem to be used. Interestingly, if I take a function it'll display the function definition - but then if I add a toString() method it will show null! var a = function(){}; console.log(a); // output: function (){} a.toString = function(){ return 'a'; }; console.log(a); // output: null a.valueOf = function(){ return 'v'; }; console.log(a); // output: null Any ideas?Read the article

jquery ajax sucess - possible to return JSON instead of string?
- by Haroldo
To return an error from a $.ajax call, there's gotta be a better way than echoing an error in the ajax.php file and then trimming it! this seems very clumsy and in-robust: success: function(e){ var e = trim(e); if(e == 'SUCCESS') {alert('your password has been changed!');} if(e == 'ERROR1') {alert('please fill in all inputs!');} if(e == 'ERROR2') {alert('password incorrect!');} if(e == 'ERROR3') {alert('change failed!');} } what should i be doing instead?!Read the article

Are there any "gotchas" to watch for in using a Class (object) within itself?
- by Clay Nichols
I've got a Registry class and there are a few Registry values that I want to access from within that Registry class. (There is a bit of a calculation with these values so I thought I'd just put all that code right in the Registry Class itself). So we might have something within our RegistryRoutine.cls like: Function GetMyValue() as integer Dim R as new RegistryRoutine <calculations> GetMyValue=R.GetRegisetryValue (HKEY, key, value, etc.) End FunctionRead the article

What is Rails way to DRY up the controller pattern of verifying :id is for a valid object (else redirect to error page)
- by jpwynn
One of my controllers has close to 100 methods (eg routes) and nearly every one starts out the same code to redirect to an error page if the id param is invalid, followed by a similar check if the user that id doesn't belong in the user's account: def something @foo = Foo.find_by_guid(params[:id]) unless @foo @msg ||= { :title => 'No such page!', :desc => "There is no such page!" } render :action => "error" and return end unless @foo.owner_id == current_user.id @msg ||= { :title => 'Really?', :desc => "There is no such page." } render :action => "error" and return end What is the best way to DRY up that sort of page id and owner id validation, given the code is doing a render ... and return? What I don't want to do at this point is offload it to a blackbox roles and permissions library like CanCan... my goal is simply to have the in-app code to handle this be as clean as possible.Read the article

How do I create if statements in php to perform a specific action depending on what form has string in it
- by user1637284
Im trying to create a grid on my page in each cell there will be a simple one line form. If a person enters data into lets say FieldA I would like the php to perform actionA but if the data was entered in FieldF I would like actionF performed. Is this possible without having to create a php for each cell and upload all those php files? Or is there a way to perform the GET method in each form to append the data to the end of the action url without the field name showing (ie sample.com/somestuff/fieldA instead of sample.com/somestuff/fieldname=fieldA) thus not needing php at all?Read the article

access a property via string with array in php?
- by sprugman
(This is in drupal, but I don't really think that matters.) I have a big list of properties that I need to map between two objects, and in one, the value that I need to map is buried inside an array. I'm hoping to avoid hard-coding the property names in the code. If I have a class like this: class Product { public $colors, $sizes; } I can access the properties like this: $props = array('colors', 'sizes'); foreach ($props as $p) { $this->$p = $other_object->$p; } As far as I can tell, if each of the properties on the left are an array, I can't do this: foreach ($props as $p) { $this->$p[0]['value'] = $other_object->$p; } Is that correct, or am I missing some clever way around this?Read the article

AS3 - Can I have access to the object (or function) who call me?
- by lk
I've asked this same question with Python. Now I like to know if this can be done in AS3. If I have something like this: package { public class SomeClass { private function A():void { C() } private function B():void { C() } private function C():void { // who is the caller, A or B ??? } public function SomeClass() { A() B() } } } Despite the design or other issues, this is only a question of an inquiring mind. Note: This has to be done without changing C signature Note 2: I like to have an access to an instance of the caller function so I can call that caller function (if I want to)Read the article
