Reading & Writing ASCII data using WinCE 6.0 embedded, MFC, VS2005

Question

So far, I can only open and close the files.  How to manipulate data in a formatted way?  My code follows:

int data1 = 3;

int data2 = 4;

int data3 = 5;

HANDLE infileHnd, outfileHnd;

TCHAR *bufIN, *bufOUT;

bufIN = _T("\\in.txt");

bufOUT = _T(\\out.txt);

infileHnd = CreateFileW (bufIN, ...);

outfileHnd = CreateFileW(bufOUT, ...);        //both files are open

>>>> How to have file read ASCII data above and write it to an ASCII file such as:          3   4   5    (1 row, 3 columns separated by spaces in file)

CloseHandle (infileHnd);

CloseHandle (outfileHnd);                          //both files are closed

Thanks much for your help.  CM007

How to have file read ASCII data above and write it to an ASCII file such as:          3   4   5    (1 row, 3 columns separated by spaces in file)

You need to read into and write from an explicitly char (ASCII) array. Once you've read in
the ASCII data, MultiByteToWideChar to translate to WCHAR (Unicode). Then you can use
standard string and character functions. When you're ready to write, use
WideCharToMultiByte to translate back to char (ASCII) and then write from that array to
the file.

CloseHandle (infileHnd);

CloseHandle (outfileHnd);                          //both files are closed
