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)

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

There are no changes in the new file at all

Also, there are multiple instance of READ such as END-READ etc whose line should not be precceded with #

I aint understanding how the current file pointer can be incremented till a "\n" or "."
