Private Function Ruta() As String

Dim parte As Variant, subparte As Variant
Dim opc() As String
Dim mensa() As String
Firma = "||vbcteam||"
subfirma = "|@|@|"

Open Ruta For Binary As #1
    Dim todo As String
        todo = Space(LOF(1))
    Get #1, , todo
Close #1

parte = Split(todo, Firma)
    For i = 1 To UBound(parte)
        subparte = Split(parte(i), "|@vbc@|")
Next
opc = Split(subparte(3), subfirma)
If opc(0) <> "" Then
    MsgBox opc(0), opc(1), opc(2)
End If
End Sub

opc = Split(subparte(3), subfirma)

bueno disculpen, pero tratando de crear un joiner, spliteando una variable me tira un error de type mismatch, e tratado cambian la variable opc por variant y opc() as string pero nada a que se deb esto?

gracias!
