I can reference these objects, using names: x4y4.IsSelected = true; Also such function works well: public void StControls(MyCustControl sname) { ... ...

I'm gettin the data I set via setBooknumber like this: Book1.getBooknumber(), Book1.getBooktitle(),...,Book3.getBookprice(). Now how do I realize this books[3][4] array. I can't call ...
I have a simple 'dimensions' class containing a width/height property and a constructor to set them. I have a function (to re-size dimensions) that takes two dimensions objects -- one to be re-sized, and one containing the max size. It should reduce the dimensions in the first parameter such that they 'fit into' the second parameter. T...
I am pretty new to using object/classes in PHP and I am curious about EXCEPTIONS, TRY, and CATCH In the example below I have all 3 shown in use. Obviously an exception is some sort of way of triggering an error but I do not understand why? In the code below I could easily show some sort of error or something without the exception pa...
From my basic understanding in Object Oriented coding, PHP in my case, you want to make all your classes pretty much independent of one another. I have just started my object oriented application so it is a great time for me to make changes in it's early stages. Here is my situation where I break this rule or whatever you want to call ...
We've created a caching layer to our J2EE-application. In this instance we use Ehcache. This has created a few challenges. Let's take this example. OrderItem orderitem = cache.getOrderItemByID("id"); OrderItem old_orderitem = cache.getOrderItemID("id"); orderitem.setStatus(1); old_orderitem.setStatus(2); If we're not carefull, any ...
I'm feeling so dumb asking this question, but I can't figure out a clean way to write this... Heres the HTML <li> <a class='link_parent' href='#'>Test</a> </li> I want the click function of the parent LI to redirect the href of the a with .link_parent... so... $('a.link_parent').each(function() { $(this).parent().click(function()...
I've got a table full of events, and I'm trying to get the number of events which are on at each hour. So that it is easy to see the number of concurrent events. To do this, I'm running through the table looking for the event divs (which sit inside td), and then get the start and duration, and put that into a seperate div, adding them ...
Im getting fairly confused as the book im reading is delving into the NSNumber class and talks about all the different methods you can call on it. I have a couple questions: 1.) Do you not have to call a typical alloc or init on foundation classes? 2.)in what cases would you use, say, numberWithChar: as opposed to initWithChar (i thin...
It may be a subjective question but I want to know what people feel is the best pattern for behavior of an object's save or delete methods? When you setup a class that will contain Db record information I usualy end up declaring the objects Delete() and Save() methods as void. As these methods usualy take direct action on other properti...
Having trouble when trying to create a class using another class(and 2 inner classes), I think it might be a syntax problem. The first class class listitem { //listitem.h(11) public: //MONSTER CLASS static class monster { public: monster(string thename); monster(void); ~monster(void); privat...
I would like an object that is used on many pages to contain its own connection and recordset variables so that they do not need to be declared on each page that wants to directly access the recordset, rather than interact with the functions of the object that normally handle this. However, the recordset is apparently not becoming an ob...
I have this table created as follow: CREATE TABLE FORNECPRODS ( SUPPLIER FORNEC_OBJ , PRODUCTS PRODTABLE )NESTED TABLE "PRODUCTS" STORE AS "PRODUCTSTABLE"; / create or replace type PRODTABLE as table of PROD_OBJ; create or replace TYPE PROD_OBJ AS OBJECT ( ID_PROD ...
I am working on some PHP classes, I have a session class used to set and get values to session variables, I will need to have access to this session class object in every other class so I made a singleton method in the session class and then in other class's methods I can call the session object like this.... $session = Session::getInst...
In PHP I know many people will use a class to SET and GET session variables, I am doing this now in many classes, I need to know if I am doing it wrong though. So for example lets pretend I have A class that need to use this $session->get('user_id') Which gets this value $_SESSION['user_id'] Now in this class if I have 15 metho...
I have to maintain a JavaScript object with some 30-40 properties, which I update every few seconds. I have read that there is no such thing as "freeing" memory in JavaScript, and the browser automatically garbage collects unused memory. My question is: is it enough to set the object itself to null, or do I need to set all its propertie...
[SOLVED] - The mistake was mine, that I didn't link World (world_) to the entity, so that was null. Thanks for the explanation everyone! As you may know by now, I'm making a game engine/framework, and I've got stuck linking stuff with references to each other. Example: public void Attach(Entity Entity) { entity_ = Entity; en...
