Ich versuche, ein Makro von MS Access 2010 von vb.net 2010 ..Wie ms Zugangsmakro von vb.net ausführen?
Der Code I ist
Dim oAccess As Access.ApplicationClass
'Start Access and open the database.
oAccess = CreateObject("Access.Application")
oAccess.Visible = True
oAccess.OpenCurrentDatabase("C:\Users\Yuganshu\Desktop\New folder (4)\WindowsApplication1\db.mdb", False)
'Run the macros.
oAccess.Run("Macro1")
'oAccess.Run("DoKbTestWithParameter", "Hello from VB .NET Client")
'Clean-up: Quit Access without saving changes to the database.
oAccess.DoCmd().Quit(Access.AcQuitOption.acQuitSaveNone)
System.Runtime.InteropServices.Marshal.ReleaseComObject(oAccess)
oAccess = Nothing
folgende Fehler Dies gibt mir verwendet auszuführen:
Unable to cast COM object of type 'Microsoft.Office.Interop.Access.ApplicationClass' to class type 'WindowsApplication1.Access.ApplicationClass'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.
Ich weiß nicht, was ich machen soll.
