We need more info than that. What exactly are you wanting to do...

dim str as string

str = environ("userName")
msgbox str

Says here there's an Environ function you can use, eg vx = Environ("PATH").

Sorry, I need to clarify my question. I did not want to determine the
contents of an environment variable! What I want to do is be able to
go out to the "command prompt" and set an arbitrary environment
variable.

I tried the following, but VBA tells me the path to the command was
not found:

dim ev_result as string

en_result = shell ("""set chris=1 2 3""")

The 3 sets of double quotes is to try to simulate doing the following
in a command prompt window: set chris="1 2 3".

Again, I want to set an environment variable within VBA.

Thank you,
Chris

Sorry again, I think I have a partial solution, if not a complete
solution! I'll try it tomorrow. Please critique me

dim ev_result as string

ev_result = shell ("\cmd ""set chris=1 2 3""")

en_result = Environ ("chris")
'en_result should be "1 2 3"

Thank you everyone in VBA land,

How do I set an environment variable to a string
 

Ah, right you are; I misread the question, reversing the subject and
predicate. Ok, I know I've run across this somewhere; I think it's a
property of one of those COM objects like wscript or WSH or something.

....Ah, here it is. Well, maybe it is. Try this:

Set ows = WScript.CreateObject("WScript.Shell")
Set oEnv = ows.Environment("SYSTEM")
oEnv("PATH") = oEnv("PATH") & ";c:\Utils"

I got this sequence from
http://msdn.microsoft.com/en-us/libr...a0(VS.85).aspx, except it
mentions only display without saying whether you can also change the
environment variable. Give it a try; maybe it'll work.

The environment variable would be alive as long as the Shell is alive--but it's
limited to that shell and its children.

So if you need to run a .bat file that needs an environment variable, you could
shell to a different .bat file that sets the environment variable and then runs
the .bat file that you need to run.

But if you want to change the environment variable globally, it's a different
story.

Win95 came with command called WinSet that did this. But I don't see it in
WinXP (at least in a normal install).

But you could search google looking for alternatives.

I've never used this, but it looks interesting:

(5) The following did not work either:

Sub test5()

Dim ev_result As String

ev_result = Shell("cmd /c set chris=""1 2 3""")
ev_result = Environ("chris")

Debug.Print ev_result '---Prints Nothing!

End Sub

Dave, I tried the following, but in the command prompt window it
said:

command, operable program or batch file.

Dave, in the interest of saving time, here is a basic test. It gives
the same results.The command prompt window said:

'%chris%' is not recognized as an internal or external
command, operable program or batch file.

Sub test7()

Dim count As Long
Dim ev_result As String

Row = 30

count = 0

ev_result = Shell("cmd /k set chris=""1 2 3"" & %chris%")
ev_result = Environ("chris")

Debug.Print "--- " & ev_result & " <---"

Debug.Print "end"
End Sub

I don't understand what this:
ev_result = Wait_("cmd /k set chris=""1 2 3"" & %chris%", "", False, True)
is doing.

And I don't understand what you're really trying to do.

Are you trying to create an environment variable that's available for just the
duration of that Shell command--and only available to the that Shell?

Or are you trying to create an environment variable that can be seen by
anything?

For every one who has not formally tuned in, I've added a few comments
to the test.
After executing the code, the command prompt windows stays around and
says:

'%chris%' is not recognized as an internal or external command,
operable program or batch file.

Chris

Sub test7()

Dim Task_ID As Variant
Dim ev_result As String

'Create shell execute a set command, and then see if can use the
contents of the variable
Task_ID = Shell("cmd /k set chris=""1 2 3"" & %chris%") '/k means
stay around, & means do 2nd cmd

'Give it another try, see if environment variable still exists
ev_result = Environ("chris")

Debug.Print "--- " & ev_result & " <---"

End Sub

I want to set an environment variable and some how later use it's
contents in a program.

After executing the code, the command prompt windows stays around and

But, I would have gotten "closer" to solving my problem if the error
had said:

'1 2 3' is not recognized as an internal or external command,
operable program or batch file.

This is because I was able to set an environment variable through VBA.

Sub test8()

Dim Task_ID As Variant
Dim ev_result As String

'Create shell execute a set command, and then see if can use the
'contents of the variable
Task_ID = Shell("cmd /k set chris=""1 2 3"" & %chris%")

'The /k means keep window around, an dthe & means do 2nd command in
same window

'Now, give it another try to see if environment variable still
exists
ev_result = Environ("chris")

Debug.Print "--- " & ev_result & " <---"

End Sub

That's all I want to do.
