I need to create a text file "setup.txt" in the location C:\Documents and Settings\All Users\Application Data\xerox\setapp in VB script the location C:\Documents and Settings\All Users\Application Data is common apllication data folder here we can use word "CSIDL_COMMON_APPDATA" or &H23& for that.Here the other which i need to take care is if any setup.txt file a开发者_C百科re already there in that location i need to remove that old one i need to insert the new "setup.txt" which contatin blank values means new one

I am new to this vbscript ,and i wanted an optimized code to acheive that functionality

You could open the file for writing and write a blank line, this will create the new text file and overwrite any previous versions.

    strFilename = " C:\Documents and Settings\All Users\Application Data\xerox\setapp.txt"
    Set objFile = CreateObject("Scripting.FileSystemObject").OpenTextFile(strFilename,2,true)
     'Write stuff to the file here
    objFile.Close
    Set objFile = nothing

It's not clear if your script is creating the log file, if not and you want to copy the file and overwrite any previous ones you could do this (setting the last argument in the CopyFile method to true will overwrite older versions).

Set fso = CreateObject("Scripting.FileSystemObject")
fso.CopyFile Source, Destination, true
Set fso = Nothing

If you just want to delete the previous file if it exists you could do this (here setting the last argument in the DeleteFile method to true will force deletion of the file).

Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FileExists(file) Then
     fso.DeleteFile file, true
End If
Set fso = Nothing

Wow, VBScript, it was a long time ago ... But I'll give it a shot.

What you need, if I understand you correctly, is to use the FileSystemObject it contains methods for deleting, creating and copying text files.

I hope this at least gives you some pointers to get you started.
