I get an error when I run the `InvokeMember` method below. The error is `UNKNOWN NAME`. I have checked the spelling and it is correct. In `Outlook` I have `Enable Macros` in the trust center. Is there anything I might be missing to get this working? Thanks

VB code:

VB

olApp.GetType().InvokeMember("nameOfMacro", Reflection.BindingFlags.InvokeMember, Nothing, olApp, {})

Well, you clearly didn't read the linked KB article in any depth.

You don't pass the name of the macro to the InvokeMember method as the method to invoke! You pass in "Run" as the method name, and the macro name as one of the arguments:

C#

private void RunMacro(object oApp, object[] oRunArgs)
{
    oApp.GetType().InvokeMember("Run",
        System.Reflection.BindingFlags.Default |
        System.Reflection.BindingFlags.InvokeMethod,
        null, oApp, oRunArgs);
}

RunMacro(olApp, new Object[]{ "nameOfMacro" });

Well, it seems InvokeMember will not work. The answer is to make the code as you would in the macro and run that. Example:

VB

Private Sub MoveAttachmentToFolder()
  Dim olNs = olApp.GetNamespace("MAPI")
  Dim subFolderA = olNs.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox).
                                         Parent.Folders("subFolderA")
  Dim subFolderB = olNs.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox).
                                         Parent.Folders("subFolderB")
  For Each mi As Outlook.MailItem In subFolderA.Items
    If mi.Attachments.Count = 1 Then
      'remember interops use 1 based arrays not zero
      Dim fileName As String = "some path" & mi.Attachments(1).FileName
      mi.Attachments(1).SaveAsFile(fileName)
      mi.Move(subFolderB)
    End If
  Next
End Sub
