    <p>I have similar problems with <code>Type mismatch</code> error only if I declare array variable in VBA in this way:</p> <pre><code>Dim anotherArray() As Variant </code></pre> <p>but the error disappears if the variable is defined in this way:</p> <pre><code>Dim anotherArray As Variant </code></pre> <p>Some other differences between your and my similar solutions are:</p> <pre><code>//C#- my solution- without array[] definition: public object[] ReturnSomeArray(object someArray) //VBA- my solution -without array() definition: Dim someArray As Variant </code></pre> <p><strong>EDIT: 2013-08-28</strong></p> <p>Working with <strong>C#-Excel-Interop</strong> I prefer try&amp;test way of searching solution. If anything works then I stick to it and sometime I miss to indicate the source of the solution or logic.</p> <p>Below you will find code which includes <code>LINQ</code> to operate with arrays. These code snippets works in both direction- get data from C# to VBA >> pass it back to C# for sorting >> return to VBA. I hope it will help you more to finally solve your problems.</p> <p><strong>First: some C# code</strong></p> <pre><code> public object[] GetSomeArray() { return new object[] { 5, 2, 1, 7, 9, 1, 5, 7 }; } public double[] ArraySorted(object tablica) { object[] obj = (object[])tablica; var filtr = from i in obj orderby Convert.ToDouble(i) select Convert.ToDouble(i); double[] wynik = (double[])filtr.ToArray(); return wynik; } </code></pre> <p><strong>Second: some VBA code</strong></p> <pre><code>Sub qTest_second_attempt() 'declare array variable Dim tmp() 'and other variables Dim addr As String addr = "UDFArrayLinqTest.ArrayLinq" 'get references Dim service1 As Object Set service1 = CreateObject(addr) 'get array from C# tmp = service1.GetSomeArray() 'pass this array to C# back to sort it Dim someArray As Variant someArray = service1.ArraySorted(tmp) 'check the result in Immediate window Debug.Print Join(WorksheetFunction.Transpose(WorksheetFunction.Transpose(someArray))) 'result: 1 1 2 5 5 7 7 9 End Sub </code></pre>

    1. COIIRC this is the key trick to getting arrays from VBA to .Net-based code and vice-versa (that is, `DIM .. As Variant` *without* the array declaration).

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.
