How can I count the number of objects of a class type within a method of that class? For that matter, how to do it outside of a class without adding the objects to a list? I should have thought of that! Thanks! I'm gonna leave it unanswered for a little while to see if there is a better way, because I agree. I'm just sortv wrapping my h...
I have a sub that handles when 14 ComboBoxes have their Index changed. I am able to cast the sender of the event, and obtain properties from there. However, after that, I want to be able to change the properties of the actual sender, rather than the cast one. How would I do this? Current code: Private Sub ComboBoxIndexChange(ByVal send...

Are many-to-many table structures defined as Value Objects in DDD? What if my many-to-many structure has a unique id? Also, what about 1-to-many relationships? For instance, if i have 2 structures Post & Comment with 1-to-many (respectively) wouldn't Comment be a Value Object since it technically cannot exist without a corresponding Pos...

Hi, It is in my understanding that referencing any DOM element in jQuery via the dollar sign (like this: $("#mydiv")), returns an object. I am looking to add an additional property to an object as such: $("#mydiv").myprop = "some value"; but this does not seem to work. I am trying to store a value in this object so I can reference it...

I have have a class that I wrote, and it seems bigger than it should be. It doesn't extend anything, and has very little going on - or so I thought - but each one is taking up just under 100k100 bytes ( thanks back2dos ). I guess that I don't have a very good understanding of what really affects how much memory an object takes up in AS3...
Hi All, This may not be possible (or might be dead easy! :) ) so here it is... I want to be able to create objects of a type that is dependant on a variable set, without the need for a big switch statement. I think it is possible in PHP to do something like... $objectType = "myNewClass"; $newObject = new $objectType(); where the $n...
I am especially interested in objects meant to be used from within C, as opposed to implementations of objects that form the core of interpreted languages such as python. ...
Ok. so I'm working on an app that retrieves items from a db and builds a gallery. I've done this a ton of times, and it should be simple. I'm running into problems, because in this gallery, I get results from a db that includes both image files, and other files. Let's just say I can't change anything but the flash, so I need to detect i...

Hi, In a separate library, we have a struct with: typedef struct bsmat{ int m; int *n; double **d; } bs; where **d is a array of pointers to double arrays. bs *new_bs(int n, double **d); There are two use cases: (a) The main application allocates multiple double matrices and calls the library to construct the structure. b = new...
I have an array of objects with various objects within to hold UI values. I wanted to have a button so that element 0's values are replicated through the whole array. However I noticed that setting one set them all. Here is an example without using any looping: console.log('manual 3: ', lis[3].spacer.divider.type); // prints 'none' lis[...
I am unsure how javascript stores objects, and references them. So, I don't know if my plan will cause bad performance. Any insight would be appreciated.
