    1. COThe first part of your answer is already explained by Reed Copsey's one (and his comments above): `.Contains` is not one of the methods of an array; you can use it with an array via `Enumerable.Contains` from LINQ. Thus, to make the OP's code work you have to account for LINQ: by adding a reference to LINQ (in .NET 3.5 and higher) or the whole LINQ library in older versions (http://stackoverflow.com/questions/2138/linq-on-the-net-2-0-runtime).

    2. COContains may be a member of System.Linq.Enumerable but you don't have to add it as a reference, at least not in .Net 4 on up, it comes "preloaded" in references. I answered the OP's question with code I tested myself in VS rather than just comment on it, maybe I should have been more clear about LINQ. For the OP, check out [link](http://msdn.microsoft.com/en-us/library/bb352880(v=vs.100).aspx) or message me if you have problems.

    3. COVarious hours before your wrote your answer, I was thinking like you (it works without reference) and that's why I refer to the comments above and to the Reed Copsey answer. Even though you can do: Dim myArray() As String myArray.Contains. This Contains is a LINQ extension method which can only be used if the LINQ reference is set in the project. You might not need to write Imports System.Linq because is preloaded (as explained in one of the aforementioned comments). The safest thing is writing Imports System.Linq anyway. If you are in a .NET before 3.5 you would have to add LINQ.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
