Eof function Eof Function [Runtime] Determines if the file pointer has reached the end of a file.

Syntax: Eof (intexpression As Integer) Return value: Bool Parameters: Intexpression: Any integer expression that evaluates to the number of an open file. 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). Example: 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, "First line of text" Print #iNumber, "Another line of text" 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
