In fact, one of the very reasons I avoided coding windows programs for quite a while was the fact that it was considerably more difficult to write code that would interact with hardware directly.

class CTest1
{
public:
    // This is your callback routine
    static void _DigitalInt(void * pData);

public:
    // This is the method that does the work.
    void DigitalInt(void);
};

void CTest1::_DigitalInt(void * pData)
{
    ((CTest1 *) pData)->DigitalInt();
}

void CTest1::DigitalInt(void)

// Do Stuff here.

Is this code correct, m_pView will initialized before the constructor called right ?
