But I maintain that all references to this function, as well as the definition of the function are of the form: __forceinline UBYTE BD_CLC(int swap,int elem); I even did a compilation with "Generate preprocessed file...
I developed a DLL in Managed C++ which loads some plugins (implemented in any .NET language) at runtime using System.Reflection.Assembly.LoadFile. The interface which is implemented by all plugins is implemented in C#. It's used by the Managed C++ code like this: #using <IMyPluginInterface.dll> // Make the 'IMyPluginInterface' type ava...
When a subclass overrides a baseclass's method, all of the baseclass's overloads are not available from the subclass. In order to use them there should be added a using BaseClass::Method; line in the subclass. Is there a quick way to inheirt the baseclass's overloads for ALL of the overridden methods? (not needing to explicitly specify ...
I have some struct containig a bitfield, which may vary in size. Example: struct BitfieldSmallBase { uint8_t a:2; uint8_t b:3; .... } struct BitfieldLargeBase { uint8_t a:4; uint8_t b:5; .... } and a union to access all bits at once: template<typename T> union Bitfield { T bits; uint8_t all; // <-...
Has anyone built a Qt S60 app (3rd edition, FP2) that plays (streaming or local) video? I want to play video 'in' a widget, not with (say) QDesktopServices. I know there's documentation about how to do this with Symbian, such as here and here but I'm still stuck. (Apologies in advance for cross-posting: I've asked elsewhere, but with ...

Hi, I am investigating a crash due to heap corruption. As this issue is non-trivial and involves analyzing the stack and dump results, I have decided to do a code review of files related to the crash. To be frank, I don't have in-depth knowledge of when the heap could be corrupted. I would appreciate if you could suggest scenarios whi...

Hi, I'm a TA for an intro C++ class. The following question was asked on a test last week: What is the output from the following program: int myFunc(int &x) { int temp = x * x * x; x += 1; return temp; } int main() { int x = 2; cout << myFunc(x) << endl << myFunc(x) << endl << myFunc(x) << endl; } The answer, to me a...
I have a couple questions. Are all functions inside of a class member functions? or only the ones preceded by the declaration "friend"? The significance of member functions are that they cannot be accessed by any other classes correct? What is the difference between an implicit and explicit call? Which functions can or cannot be imp...
