As alluded to by Eric, you can use environ with ComputerName argument like so:
MsgBox Environ("USERNAME")
Some additional information that might be helpful for you to know:
- The arguments are not case sensitive.
- There is a slightly faster performing string version of the Environ function. To invoke it, use a dollar sign. (Ex: Environ$("username")) This will net you a small performance gain.
- You can retrieve all System Environment Variables using this function. (Not just username.) A common use is to get the "ComputerName" value to see which computer the user is logging onto from.
- I don't recommend it for most situations, but it can be occasionally useful to know that you can also access the variables with an index. If you use this syntax the the name of argument and the value are returned. In this way you can enumerate all available variables. Valid values are 1 - 255.
Sub EnumSEVars()
Dim strVar As String
Dim i As Long
For i = 1 To 255
strVar = Environ$(i)
If LenB(strVar) = 0& Then Exit For
Debug.Print strVar
Next
End Sub
