Replace Text in a Text File

[its]

I have a Text file and need to replace some data in each line (Row Length is 55) from this Text File. Need to Replace Data from Position 11-19 on each Row, - 9 digits with something else like 123456789 (some random nos).

Please help me with code

<%
Set fs=Server.CreateObject("Scripting.FileSystemObject ")

Set f=fs.OpenTextFile(Server.MapPath("MyTextFile.txt") , 1)



f.Close
Set f=Nothing
Set fs=Nothing
%>

So you have no choice but to read from one file and write to another.
And just use string manipulation to change the line contents.

example:

line = fromFile.readLine
front = Left(line,10)
back = Mid(line,20)
line = front & "123456789" & back
toFile.writeLine line

And do that in a loop for the entire file.
