WriteFile/ReadFile repeat last lines

Hi

Code:

---

        do
        {
                bReadSuccess = ReadFile( hFile, strBuffer, sizeof(strBuffer), &nRead, NULL);
                bWriteSuccess = WriteFile( hFile2, strBuffer, sizeof(strBuffer), &nWrite, NULL);
        }while(bReadSuccess && bWriteSuccess && (nRead > 0));

---

a.txt's last line is:
315614,05r re regf

b.txt's last lines are:
315614,05r re regf
315614,05r re regf
315614,05r re

What is wrong with that loop?
Thanks.

nRead doesn't has to be sizeof(strBuffer) if the buffer isn't fully filled, this probably creates the wierd lines. You are writing more that you read.

Understood.
Solved it:

Code:

---

        do
        {
                bReadSuccess = ReadFile( hFile, strBuffer, sizeof(strBuffer), &nRead, NULL);
                bWriteSuccess = WriteFile( hFile2, strBuffer, nRead, &nWrite, NULL);
        }while(bReadSuccess && bWriteSuccess && (nRead > 0));
