    Re: To be or not to be (a console app)

    You're welcome :).
    Also my code made sure it didn't break the command:
    EXENAME > echo.txt
    To make sure your app doesn't break that command, you need to adapt IsAConsole at the least like:

    This is what ~cConsoleInitializer did


    ~cConsoleInitializer()
    {
    if( File )
    {

    Re: To be or not to be (a console app)

    This seems like what you want:
    #include <windows.h>
    #include <iostream>
    #include <cstdio>

    bool IsAConsole( HANDLE Handle )
    {
    DWORD Mode;
    return GetConsoleMode( Handle, &Mode ) != 0;...

    Re: Variadic function pointer

    To be more elaborate about trying &Class.myfunction from my previous post. The compiler will complain about trying to form a pointer by taking the address of a bound member function.

    Re: Reference to a pointer of another type

    I am confused about what you mean, but how about

    class A{};
    class B : public A{};

    int main()
    {
    A* pA = new B;
    B& pB1 = static_cast<B&>(*pA);
    }

    Why not learn from tutorials as well? Also read faqs. They can provide common pitfalls and how to avoid them. Googling your question first is even better if you can generalize it.

    I wouldn't inherit a shared_ptr since the destructor isn't virtual. Also shared_ptr only destroys the object it contains only after all shared_ptrs destruct, so if a user clicks the exit button, you...

    Re: [RESOLVED] Creating a window in a DLL

    Also don't forget to unregister your class since dlls do not unregister classes automatically.

    Also are you sure there isn't a better way to pass HWND? Can you at least pass pointers?
