    <p>I am simply pasting below the code by the great Chip Pearson.<br> Also check out his <a href="http://www.cpearson.com/excel/vbaarrays.htm" rel="nofollow noreferrer">page on array functions</a>.</p> <p>I hope this helps.</p> <pre><code>Public Function IsArrayEmpty(Arr As Variant) As Boolean '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' IsArrayEmpty ' This function tests whether the array is empty (unallocated). Returns TRUE or FALSE. ' ' The VBA IsArray function indicates whether a variable is an array, but it does not ' distinguish between allocated and unallocated arrays. It will return TRUE for both ' allocated and unallocated arrays. This function tests whether the array has actually ' been allocated. ' ' This function is really the reverse of IsArrayAllocated. ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' Dim LB As Long Dim UB As Long err.Clear On Error Resume Next If IsArray(Arr) = False Then ' we weren't passed an array, return True IsArrayEmpty = True End If ' Attempt to get the UBound of the array. If the array is ' unallocated, an error will occur. UB = UBound(Arr, 1) If (err.Number &lt;&gt; 0) Then IsArrayEmpty = True Else '''''''''''''''''''''''''''''''''''''''''' ' On rare occassion, under circumstances I ' cannot reliably replictate, Err.Number ' will be 0 for an unallocated, empty array. ' On these occassions, LBound is 0 and ' UBound is -1. ' To accomodate the weird behavior, test to ' see if LB &gt; UB. If so, the array is not ' allocated. '''''''''''''''''''''''''''''''''''''''''' err.Clear LB = LBound(Arr) If LB &gt; UB Then IsArrayEmpty = True Else IsArrayEmpty = False End If End If End Function </code></pre>

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.
