[Visual FoxPro 9.0] Problème dll COM
Bonjour,
Je suis en train de faire un webservice en foxpro.
Je fait l'interface en ASP.Net (asmx) et des appels à un COM fait en foxpro [parce que le toolkit soap est décoinseillé].

L'erreur que j'ai (erreur générée par .Net) est "System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to class type 'wsorder.WsOrder_CodeDateClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface."
Donc en somme (et selon moi), .Net m'indique que ReturnValue n'est pas typé de façon exploitable.
Est-ce que je fais quelque chose de travers ?
Est-ce que je peux essayer quelque chose ?
Merci pour votre aide.
