Any valid file number
A Boolean indicating when the end of the file has been reached
Returns a Boolean indicating when the end of the file has been reached. Applies to files opened for binary, random, or sequential input.
filenumber must be an Integer that
specifies a valid file number.
If a file is opened for binary access, you cannot use
EOF with the
Instead, use LOF and Loc.
If you want to use EOF, you must use
FileGet rather than
this case, EOF returns
until the previous FileGet procedure is unable
to read an entire record.
Dim fr As Integer = FreeFile( ) Dim sLine As String FileOpen(fr, "c:\data.txt", OpenMode.Input, OpenAccess.Read, _ OpenShare.Default, -1) Do While Not EOF(fr) sLine = LineInput(fr) Console.WriteLine(sLine) Loop
EOF allows you to test whether the end of a file has been reached without generating an error.
Because you always write data to sequential files at the end of the
file, the file marker is always at the end of the file, and
EOF will therefore always return
True when testing files opened with their modes
set equal to either
