Question

I would like to do a vlookup from a close file to an active open file, The path of the closed file will be given as a variant

Lets say mypath = \"C:\\li

Answer 1

You will need the full path.

Example

Option Explicit
Public Sub Example()
    Dim Path As String

    Path = "C:\Temp\"

    With ThisWorkbook.Sheets("Sheet1")
        .Range("B1").Formula = "=VLOOKUP(A1,'" & Path & "[Book1.xlsx]Sheet2'!A:J,3,FALSE)"
    End With
End Sub

VLOOKUP function

Answer 2

As long as @0m3r's solution answers the question here is a small contribution to anyone who is looking to reference a closed file located in Desktop.

Even not specific for one user, works on any other user as well.

Option Explicit
Public Sub Example()
    Dim yourdesktopaddress As String 

    yourdesktopaddress = CreateObject("WScript.Shell").specialfolders("Desktop")

'or if you would like to reference another folder located in Desktop (i.e: SpecificFolderOnTheDesktop)
    'Dim folderinthedesktopaddress as String
    'folderinthedesktopaddress = CreateObject("WScript.Shell").specialfolders("Desktop") & "\SpecificFolderOnTheDesktop"

    With ThisWorkbook.Sheets("Sheet1")
        .Range("B1").Formula = "=VLOOKUP(A1,'" & yourdesktopaddress & "[Book1.xlsx]Sheet2'!A:J,3,FALSE)"
    End With
End Sub
