VBScript-修改Windows环境变量

Question

I currently use a batch file to override some environment variables to make a game portable.

Mainly the below:

Set USERPROFILE = %CD%

This only stays in effect through that session or through a program loaded from the batch. So when I load the game through it with:

Start "" "FL.exe"

The game treats the My Documents, My Pictures and AppData folders as being within my game folder.

Can this functionality be replicated within VBScript at all?

Yes, through the WshShell.Environment object. You can query, add, and remove environmental variables at the system, user, and process level.

For example:

Set objShell = CreateObject("WScript.Shell")
Set objProcessVars = objShell.Environment("process")

' Query existing environmental variables...
For Each objVar In objProcessVars
    WScript.Echo objVar
Next

' Add/Override a process-level variable...
objProcessVars("USERPROFILE") = "C:\Test"

' Spawned processes inherit your process-level variables...
objShell.Run "C:\AnotherScript.vbs"

' When script terminates, changes are lost.
