FilePermissiosn in VBScript

How can I set the FilePermissions in a VBScript ? I have tried:

Dim myPermissions
Set myPermissions = Wscript.CreateObject("WinSCP.FilePermissions")
myPermissions.FilePermissions.Text = "rwxrwxrwx"

also tried:

Set transferOptions = WScript.CreateObject("WinSCP.TransferOptions")
transferOptions.TransferMode = TransferMode_Binary
transferOptions.FilePermissions.Text = "rwxrwxrwx"

Both returns "missing object"

I do not do VBScript, but I guess this should do:
