Use EOF to avoid errors when you attempt to get input past the end of a file. When you use the Input or Get statement to read from a file, the file pointer is advanced by the number of bytes read. When the end of a file is reached, EOF returns the value "True" (-1).
Contoh:
Sub ExampleWorkWithAFile
Dim iNumber As Integer
Dim sLine As String
Dim aFile As String
Dim sMsg As String
aFile = "c:\data.txt"
iNumber = Freefile
Open aFile For Output As #iNumber
Print #iNumber, "Baris pertama teks"
Print #iNumber, "Baris teks lainnya"
Close #iNumber
iNumber = Freefile
Open aFile For Input As iNumber
While Not eof(iNumber)
Line Input #iNumber, sLine
If sLine <>"" Then
sMsg = sMsg & sLine & chr(13)
End If
Wend
Close #iNumber
MsgBox sMsg
End Sub
