VBSCRIPT - Run a macro from a securised Access Database

I'm writing a VBScript that will run a macro from a secured Access database :

Database : c:\afac\test.mdb
SystemDB (not secured) : c:\afac\system.mwd
SystemDB (secured) : c:\afac\NewSystem.mdw (user = test - password = PwdTest)

Example 1 : my database is not secure -> no problem :

Dim oAccess
Dim oWorkspace
Set oAccess = CreateObject("Access.Application")
oAccess.SetDefaultWorkgroupFile("c:\afac\System.mdw")
oAccess.OpenCurrentDatabase "c:\afac\test.mdb"
oAccess.DoCmd.RunMacro "Macro"
oAccess.CloseCurrentDatabase
oAccess.Quit

Example 2 : my database is secure -> problem : How can I say who is the user and what is the password ?

Dim oAccess
Dim oWorkspace
Set oAccess = CreateObject("Access.Application")
oAccess.SetDefaultWorkgroupFile("c:\afac\NewSystem.mdw")
oAccess.OpenCurrentDatabase "c:\afac\test.mdb"  ' -> Microsoft Office Access can't open the database because it is missing, or opened exclusively by another user.
oAccess.DoCmd.RunMacro "Macro"
oAccess.CloseCurrentDatabase
oAccess.Quit

Thanks for your help
