    Re: conversions

    Because 480/768 is zero, when you're dealing with integers. Convert them to float before doing the division. Like this:

    Re: Font for CButton

    I think fonts are part of the theme, so it will use those instead of the one you pass.

    To remove a theme from a window, call
    SetWindowTheme(hwnd, L"", L"");

    where hwnd is the hwnd of your...

    Re: IMPLEMENT_DYNCREATE and abstract base classes

    Oops, I kind of posted a bad example above. I didn't realize CScrollView was actually an MFC class!

    Ok, well pretend its actually my own class, with pure virtual methods on it.

    Re: Waiting in GUI till thread ends

    Give your dialog's hwnd to the thread. When the worker thread ends, have it post a message to your dialog to tell it that it's done.

    Make your own message, e.g.
    #define WM_MYTHREADENDED WM_USER...

    Re: How to set default size of MDI child frame?

    Actually, PreCreateWindow doesn't work so well, because if I increase the size, MFC starts putting these things off the MDI area, and the user has to move them completely back on (e.g. the bottom is...

  14. How do I make my dialog show up if it is doing work?

    I have lengthy action that has a progress dialog. The dialog itself initiates the action: it spawns a worker thread and communicates with it using events.

    Re: memcpy driving me crazy

    It looks like your buffer is 16 characters long, and m_a, m_b, m_c and m_d all have values the ascii character '0'. So it's behaving as expected.

    Your buffer isn't null-terminated, so if you...

    Hmm... but that value will change millions (billions?) of times a second just executing regular code.
    Maybe you're interested in if it changes at just one particular spot in the code?
