Problem with system constants

TheWshShell.ExpandEnvironmentStrings function returns the systems constants
like "C:\Windows" for
"%SYSTEMROOT%".
But how to set one of this constants?
I tried WshShell.Run "set DAN = c:\"
but I get "Couldn't find the file" (I translated it from my language so it
may sound a little diffrent)
Please help,
zurg

Hi

Create/set/change environment variables permanent (WNT/W2k/WXP) from VBScript:

'Example for setting a environment variable with name "ASSET" and value "1234"

Set WshShell = CreateObject("WScript.Shell")

' makes environment settings permanent and for all users
' Use "USER" instead of "SYSTEM" to set it for current
' user only, or "PROCESS" to set it for current process only
Set WshSystemEnv = WshShell.Environment("SYSTEM")

' Set your environment variable
WshSystemEnv("ASSET") = "1234"


For Win9x/WinME, only "PROCESS" is available.


For SYSTEM and USER, you usually need a logoff/logon to make the changes take
affect.

Thanks for the complete answer - it's god to get all informations about the
subject!
But... doesn't work???
I run this code and tried "set" and "%ASSET%" from the command line and it
didn't return "1234"...
Why?

Code like this:

Set WshShell = CreateObject("WScript.Shell")
Set WshSystemEnv = WshShell.Environment("SYSTEM")
WshSystemEnv("ASSET") = "1234"

Hi

After running this script, if I open a new command prompt and type SET, I see
the new env. variable. If you want to see it from the script that made the env.
variable, you should set it in the PROCESS environment as well as in the
SYSTEM.

Sorry, your're right... I just wrote in command line sth like this:
1. "cscript 1.vbs"
2. "set"
So it didn't returned newly registed value
Too fast - my failure...
Thank you once again,
