Hi,

This forum is for posting the questions related to asp . So if you want to post your question regarding VB you have to post it in the respected forum.

The functionality that you require can be done using following lines of code :

Code:

Private Function DeleteLines(ByVal from_name As String, _
    ByVal to_name As String, ByVal target As String) As Long
Dim strlen As Integer
Dim from_file As Integer
Dim to_file As Integer
Dim one_line As String
Dim deleted As Integer

    ' Open the input file.
    from_file = FreeFile
    Open from_name For Input As from_file

    ' Open the output file.
    to_file = FreeFile
    Open to_name For Output As to_file

    ' Copy the file skipping lines containing the
    ' target.
    deleted = 0
    Do While Not EOF(from_file)
        Line Input #from_file, one_line
        If InStr(one_line, target) = 0 Then
            Print #to_file, one_line
        Else
            deleted = deleted + 1
        End If
    Loop

    ' Close the files.
    Close from_file
    Close to_file

    DeleteLines = deleted
End Function
