I have a form that I am attempting to override the WndProc subroutine on. I am using GetDCEx to get a DC handle to my form. According to Microsoft's documentation on using GetDCEx, my form must have the CS_OWNDC or the CS_PARENTDC flag set my window class in order to use GetDCEx.

I'm making a game with three main panels and a few subpanels, and I'm confused about how you "connect" the panels and their data. I have my main class, which extends JFrame and adds three JPanels. Each of those panels is a subclass of JPanel. (Ex: JPanel gameControlPanel = new GameControlPanel(), where GameControlPanel is a class I crea...

Hi I have large forms in my GWT webapp. I'm using SmartGWT. The problem is that the classes that implements the forms are too large. The main reason is because each form has one or two TabSets with multiple tabs. The question is: Should I split this classes? Maybe one per tab? Each class is responsible of instantiate the form (the most...
Hello guys, g++ is letting out an obscure error, undefined reference to '__gxx_personality_sj0' in two lines of my project. What does this mean in this context? I googled a lot and found out this is usually related to the inclusion of C code in C++ or something like that, which is not what I'm going for. (I know the code isn't high qual...

In .NET, integer data type is a value type(stack) and String is a reference type(heap). So If a class A has an integer, and a string type object in it, and a class B creates an object of class A, then how will this object of class A be stored in memory? In stack, or in a heap? This was asked in my Microsoft interview. Need to understan...

Hello. I am trying to make a FIFO Queue that is filled with my own class object. I found this example but if I replace < E > with < PCB > it does not work: import java.util.LinkedList; public class SimpleQueue<E> { private LinkedList<E> list = new LinkedList<E>(); public void put(E o) { list.addLast(o); } public E ge...
I understand that one benefit of having static member functions is not having to initialize a class to use them. It seems to me that another advantage of them might be not having direct access to the class's not-static stuff. For example a common practice is if you know that a function will have arguments that are not to be changed, to...

I am trying to create a List of properties for objects. I can create a list for basic objects just fine, but if I have a situation where type object A contains a property of type object B which contains a property of type object A.... well.. then I get infinite recursion.
