Why ????

I wrote 2 files, "Extra.h" and "Extra.cpp"
Why the compiler said:
c:\my documents\receipt\extra.cpp(21) : fatal error C1010: unexpected end of file while looking for precompiled header directive
here is the code of extra.cpp

// implementation of extra functions
/////////////////////////////////////

// change to real date value
void ToReal(int &nDay,int &nMonth,int &nYear)
{
nDay=nDay+1;
nMonth=nMonth+1;
nYear=nYear+1999;
}

// change to combo box value
void ToFake(int &nDay,int &nMonth,int &nYear)
{
nDay=nDay-1;
nMonth=nMonth-1;
nYear=nYear-1999;
}



Here is the header file Extra.h

// this file to contain prototype for extra functions
///////////////////////////////////////////////////

// change value of m_nDay, m_nMonth and m_nYear back and forth

//change to real value of date
void ToReal(int &nDay,int &nMonth,int &nYear);

// change to combo box value
void ToFake(int &nDay,int &nMonth, int &nYear);



Thanks

In the header file put the word "extern" in front of the declarations and let me know if that works.

In the .cpp file, before including Extra.h, you need to include stdafx.h.
#include "stdafx.h"
#include "Extra.h"

nordyj is right, I just assumed you did that.
