Visual Basic - Esperar hasta que termina aplicación DOS

Hola!!, como puedo hacer que visual Basic se espere hasta que termine un proceso en DOS, especificamente un proceso .bat??. Necesito que se procese serialmente, no en paralelo.

Agradecere muchisimo su ayuda....gracias

Fijate con esto:

Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long

Private Declare Function GetExitCodeProcess Lib "kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long

Const STILL_ACTIVE = &H103
Const PROCESS_QUERY_INFORMATION = &H400

Dim hProcess As Long
Dim RetVal As Long
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, False, Shell("MiComando", vbMinimizedNoFocus))

Do
GetExitCodeProcess hProcess, RetVal
DoEvents
' Sleep 100
Loop While RetVal = STILL_ACTIVE
End Sub
