I have the following code to open a csv file for writing. To make a unique
name for the file I make use of the Now() function. E.g. I get the file name :

C:\HF\Excel\Work\Naam_20090320_130144.csv

However, when run on another machine with different date time setting it
could result in :

C:\HF\Excel\Work\Naam_-200Ma_1:0:4:3.csv

Which result in an error.

How can I make sure that I will always get the first result?


Code :

Dim ThisDirectory As String
ThisDirectory = ActiveWorkbook.Path
Dim TimeStamp As String
TimeStamp = Mid(Now(), 7, 4) & Mid(Now(), 4, 2) & Mid(Now(), 1, 2) &
"_" & Mid(Now(), 12, 2) & Mid(Now(), 15, 2) & Mid(Now(), 18, 2)
Dim csvFileName As String
csvFileName = ThisDirectory & "\Naam_" & TimeStamp & ".csv"
Dim ReadyText As String

Set csvObject = CreateObject("Scripting.FileSystemObject")
Set csvFile = csvObject.CreateTextFile(csvFileName, True)

TimeStamp = Format(Now(),"YYYYMMDD_hhmmss")

Dim ThisDirectory As String
ThisDirectory = ActiveWorkbook.Path
Dim TimeStamp As String
TimeStamp = Mid(Now(), 7, 4) & Mid(Now(), 4, 2) & Mid(Now(), 1, 2) &
"_" & Mid(Now(), 12, 2) & Mid(Now(), 15, 2) & Mid(Now(), 18, 2)

csvFileName = ThisDirectory & "\Naam_" & TimeStamp & ".csv"

If you just want the timestamp, use

csvFileName = ActiveWorkbook.Path & "\" & _
"Naam_" & _
Format(Now,"ddmmyyyyhhmm") & ".cvs"

It is theoretically possible, though quite unlikely, that two users
might get the same value for the time stamp. If you really want a
universally unique number, use a GUID. For example,

csvFileName= ActiveWorkbook.Path & "\" & _
"Naam_" & CreateGUID() & ".csv"

The code for CreateGUID is at
http://www.cpearson.com/Excel/CreateGUID.aspx .
The GUID will be unique across all users, all computers, and all
networks. Though unique, there is no meaningful information in a GUID.

You have two suggestions to use Format. For my curiosity could you confirm
they work correctly, in particular does the "yyyy" help provide the correct
year in your non English version. Just wondering if perhaps it should be
"jjjj", assuming jaar = year for you.
