Функции API CreateDesktop и CreateProcess - как их правильно вызвать? - VB

Формулировка задачи:

Помогите с вызовом функции. Что не так? Например CreateProcess. Меняю стандартное объявление функции как:

Private Declare Function CreateDesktop Lib "user32" Alias "CreateDesktopA" (ByVal lpszDesktop As String, ByVal lpszDevice As String, pDevmode As DEVMODE, ByVal dwFlags As Long, ByVal dwDesiredAccess As Long, lpsa As SECURITY_ATTRIBUTES) As Long

На объявление:

Private Declare Function CreateDesktop Lib "user32" Alias "CreateDesktopA" (ByVal lpszDesktop As String, ByVal lpszDevice As String, ByVal pDevmode As Long, ByVal dwFlags As Long, ByVal dwDesiredAccess As Long, ByVal lpsa As Long) As Long

Вызываю функцию следующим образом:

Private Const DESKTOP_CREATEWINDOW = &H2&
lngRetval = CreateDesktop("NewDeskTop", vbNull, vbNull, 0, DESKTOP_CREATEWINDOW, vbNull)

Как результат – фатальное исключение.
