Use CStdioFile and its methods.

If you're using a Text file try this:

try
{
CString sFileLine;
CStdioFile fileRead(sFilePathName, CFile::modeRead |
CFile::typeText);

while (fileRead.ReadString(sFileLine))
{
....whatever
}
}
catch (CFileException* e)
{
e->ReportError();
e->Delete();
}

If you're not using a text file then you'd be better of declaring an array of 'unsigned char' type to hold the info:

[tt]unsigned char* buffer = new unsigned char[bufferSize];

// read stuff into buffer here

// don't forget to 'delete' the buffer when finished!
delete []buffer;[/tt]

Forgot to mention - this is because if you use a CString, it will get chopped off at any zero character!
