Well, I didn’t expect the cat to get out of the bag quite so quickly! (Congratulations go out to Stoinov for getting the correct answer I was thinking of so very quickly!) So while he’s been sleeping during his night, which seems to be my day… I thought I’d throw together a quick “Write a text file” script together for you all. (A little trivia for you all in the United States, that I found hard to believe when I learned it… VBScript, and VB for that matter, is in English regardless of where you are in the world. If you’re on a Japanese system writing VBScript, your using the same language as us folks in the United States. Talk about portable code!)
Back to the matter at hand, this script doesn’t do anything terribly spectacular– by itself. All it does is opens (or creates) a text file named what you call it where you specify. The heart of the script is the WriteTextFile () function, which accepts two pieces of data; a full path to a file name and the data you want to write. That’s it! But—- this function will let you write logs, CSV (Comma Separated Value) files or any other form of text file from any type of script for which you choose to use it!
A quick little note on the access method I hard coded into the script. You will notice three constants used ForReading, ForWriting, and ForAppending these are there so you could change the mode easily without having to go to the documentation for the OpenTextFile Method of the Scripting.FileSystemObject and figure out what numbers to use to change the access method. you simply just need to change the access method from ForReading on the OpenTextFile line of the script to accomplish this task. An excerpt of the Microsoft documentation for the values and descriptions are listed below, for your reference.
|ForReading||1||Open a file for reading only. You can’t write to this file.|
|ForWriting||2||Open a file for writing.|
|ForAppending||8||Open a file and write to the end of the file.|
Notice it has a ForAppending attribute? If you wanted to … say log a series of collected values over a number of calls to the script you would have to change the access method to appending, however, keep in mind that ForAppending assumes the file already exists and you will receive an error if it doesn’t.
So, here is the script to write a file…
Error = WriteTextFile (“c:\test.txt”, “I created a text file with VBScript!”)
If Error = 0 Then
WScript.Echo “File Written Correctly.”
WScript.Echo”Error number ” & Error & ” occurred.”
Function WriteTextFile (OutputFile, Data)
Dim wrtlog, fso
‘these are constants for the OpenTextFile method’s file access modes
Const ForReading = 1, ForWriting = 2, ForAppending = 8
On Error Resume Next
Set fso = CreateObject(“Scripting.FileSystemObject”)
Set wrtlog = fso.OpenTextFile (OutputFile, ForWriting , true)
WriteTextFile = Err.Number ‘You can use Err.Description here to debug.
That’s it. Small, but a VERY powerful tool to add to your tool belt in scripting.
As always, this code works perfectly. However, sometimes the formatting of the blog breaks the code if you copy and paste it into your editor. So, if you’d like to not type or troubleshoot any syntax errors due to the copy and paste problems– I’ve provided the code for download, plus example output files from my final tests for you. You’ll find the code and other files available for download from my website’s (www.websystemsadministration.com) File Depot under the ITKE Blog Scripts category. Enjoy and happy scripting!
