Office 12 word automation

Bonjour,

Je viens d'installer la Béta 2 d'Office 12 pour effectuer quelques tests
A peine terminé que je me heurte à mon premier problême et je n'y trouve pas de solutions
malgré mes recherches.



Imports Microsoft.Office.Interop

Dim wa AS New Word.Application
Dim _mDoc as Word.Document

_mDoc = _wa.Documents.Open(Ctype("Test.Doc",Object))


Erreur 1 La résolution de surcharge a échoué, car aucun 'Open' accessible n'est plus spécifique pour ces arguments :
'Public Function Open(ByRef FileName As Object, [ByRef ConfirmConversions As Object],
[ByRef ReadOnly As Object], [ByRef AddToRecentFiles As Object],
[ByRef PasswordDocument As Object], [ByRef PasswordTemplate As Object],
[ByRef Revert As Object], [ByRef WritePasswordDocument As Object],
[ByRef WritePasswordTemplate As Object], [ByRef Format As Object],
[ByRef Encoding As Object], [ByRef Visible As Object],
[ByRef OpenAndRepair As Object], [ByRef DocumentDirection As Object],
[ByRef NoEncodingDialog As Object], [ByRef XMLTransform As Object],
[ByRef NoAutoRepairDialog As Object])
As Microsoft.Office.Interop.Word.Document': Pas plus spécifique.

Bon je veux bien mais sauf erreur le seul paramêtre obligatoire est le nom de fichier



Si quelqu'un à la solution ou un debut d'explication, je suis preneur

Merci d'avance
