    <p>There is no 'secret sauce' added to the latest F# CTP release (Visual Studio 2010 Beta1) to improve Office interop. Perhaps you have F# confused with <a href="http://msdn.microsoft.com/en-us/library/dd264733(VS.100).aspx" rel="noreferrer">C#'s new support for Dynamic</a>.</p> <p>However, Office interop in F# is the same as C# - you can use the native COM APIs or the newer, managed Visual Studio Tools for Office (VSTO) libraries. Unfortunately F# doesn't have the UI-designers for creating VSTO add-ins like C#, so the simplest way to do Office interop is to use the COM APIs.</p> <p>The following snippet creates an Excel worksheet with information about the pictures in your My Pictures folder:</p> <pre><code>#r "Microsoft.Office.Interop.Excel" open System open System.IO open System.Reflection open Microsoft.Office.Interop.Excel let app = ApplicationClass(Visible = true) let sheet = app.Workbooks .Add() .Worksheets.[1] :?&gt; _Worksheet let setCellText (x : int) (y : int) (text : string) = let range = sprintf "%c%d" (char (x + int 'A')) (y+1) sheet.Range(range).Value(Missing.Value) &lt;- text let printCsvToExcel rowIdx (csvText : string) = csvText.Split([| ',' |]) |&gt; Array.iteri (fun partIdx partText -&gt; setCellText partIdx rowIdx partText) let rec filesUnderFolder basePath = seq { yield! Directory.GetFiles(basePath) for subFolder in Directory.GetDirectories(basePath) do yield! filesUnderFolder subFolder } // Print header printCsvToExcel 0 "Directory, Filename, Size, Creation Time" // Print rows filesUnderFolder (Environment.GetFolderPath(Environment.SpecialFolder.MyPictures)) |&gt; Seq.map (fun filename -&gt; new FileInfo(filename)) |&gt; Seq.map (fun fileInfo -&gt; sprintf "%s, %s, %d, %s" fileInfo.DirectoryName fileInfo.Name fileInfo.Length (fileInfo.CreationTime.ToShortDateString())) |&gt; Seq.iteri (fun idx str -&gt; printCsvToExcel (idx + 1) str) </code></pre>

    1. COHi Chris, this is insane. I was just watching this video by Dom Syme http://channel9.msdn.com/Blogs/David+Gristwood/An-F-Tutorial-with-Don-Syme-2-of-4 where he does soem explorative codig with F#. I thought that was cool. Being able to slap on Excel as a front end just boggles the mind. Thanks!

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.
