How to change Hard coded path
Hi, I have a script but I have no idea how to replace hard coded path in it, if I`m changing anything then it is not working anymore, can some experienced guy look in it and give me advice?:
On Error Resume Next
Set objFSO = CreateObject("Scripting.FileSystemObject")
'Sets variables
FilePath="c:\windows\system32\drivers\etc\hosts"
SearchTerm="# 127.0.0.1 localhost"
NewText=" 127.0.0.1 localhost"
'Opens text file in read mode (Read=1, Write=2, Append=8)
Set objFile = objFSO.OpenTextFile(FilePath, 1)
'Adds all text in text file to "FileContent" string
FileContent = objFile.ReadAll
objFile.Close
'Instr searches "FileContent" looking for "SearchTerm", if not found returns 0
if Instr(FileContent,SearchTerm) = 0 then
'Not found code
'Opens text file in append mode so you can add text (Read=1, Write=2, Append=8)
Set objFile = objFSO.OpenTextFile(FilePath, 8)
'Writes new line to text fle vbCrLf inserts a return(s) to ensure new line
objFile.WriteLine (vbCrLf & NewText & vbCrLf)
objFile.Close
Else
'Found search term
ReplaceOldLine = Replace(FileContent, "# 127.0.0.1 localhost", NewText)
'Opens text file in write mode to replace old line (Read=1, Write=2, Append=8)
Set objFile = objFSO.OpenTextFile(FilePath, 2)
're-writes whole content of file with replaced values (if needed)
objFile.WriteLine ReplaceOldLine
objFile.Close
end If
WScript.Quit

The number of space between # and 127.0.0.1 in the script should match with the number of space between # and 127.0.0.1 in your host file.. :) - jagadeish 12 years ago

Also.. The number of space between 127.0.0.1 and localhost in the script should match with the number of space between 127.0.0.1 and localhost in your host file.. :) - jagadeish 12 years ago
