DAO y abrir formulario de Access

No te sirve la conexion por DAO, debes referenciar (menu referencias) Microsoft Access 10.0 Object Library y desde ahi instanciar un objeto tipo access.
Luego, abre la BBDD con sentencias de este tipo :
Dim objAcces As New Access
call Access.OpenAccessProject ([NombreArchivo], [ModoexlusivoSi/NO])
Luego juega con la estructura :
Access. Application
Espero que te sea util.
Access. Application. Forms tiene los formularios...
Etc.
Suerte

Veras lo que hago.
Public workBD As Workspace
Public FileBD As Database
Public regisBD As Recordset
Set workBD = DBEngine.Workspaces(0)
Set FileBD = workBD.OpenDatabase("C:\Usr\prueba.mdb", , True)
Set regisBD = FileBD.OpenRecordset("elementos", dbOpenDynaset)
'Aqui hago varias cosas. Tengo menus y opciones. Inserto registros, etc.
regisBD.Close
FileBD.Close
workBD.Close
Dim appaccess As Access.Application
Set appaccess = New Access.Application
appaccess.OpenCurrentDatabase ("c:\usr\prueba.mdb")
appaccess.DoCmd.OpenForm nombre_formulario, acNormal
Esto es lo que intento hacer (resumido) y no me abre el formulario. Tampoco me da ningún error.

Es que no recuedo la propiedad para maximizar acces, pero...
Bueno, si esto no te vale la busco.

Perdona, pero no entiendo para que es esto.
