    <p>I just finish writing my first F# program. Functionality wise the code works the way I wanted, but not sure if the code is efficient. I would much appreciate if someone could review the code for me and point out the areas where the code can be improved.</p> <p>Thanks Sudaly</p> <pre><code>open System open System.IO open System.IO.Pipes open System.Text open System.Collections.Generic open System.Runtime.Serialization [&lt;DataContract&gt;] type Quote = { [&lt;field: DataMember(Name="securityIdentifier") &gt;] RicCode:string [&lt;field: DataMember(Name="madeOn") &gt;] MadeOn:DateTime [&lt;field: DataMember(Name="closePrice") &gt;] Price:float } let m_cache = new Dictionary&lt;string, Quote&gt;() let ParseQuoteString (quoteString:string) = let data = Encoding.Unicode.GetBytes(quoteString) let stream = new MemoryStream() stream.Write(data, 0, data.Length); stream.Position &lt;- 0L let ser = Json.DataContractJsonSerializer(typeof&lt;Quote array&gt;) let results:Quote array = ser.ReadObject(stream) :?&gt; Quote array results let RefreshCache quoteList = m_cache.Clear() quoteList |&gt; Array.iter(fun result-&gt;m_cache.Add(result.RicCode, result)) let EstablishConnection() = let pipeServer = new NamedPipeServerStream("testpipe", PipeDirection.InOut, 4) let mutable sr = null printfn "[F#] NamedPipeServerStream thread created, Wait for a client to connect" pipeServer.WaitForConnection() printfn "[F#] Client connected." try // Stream for the request. sr &lt;- new StreamReader(pipeServer) with | _ as e -&gt; printfn "[F#]ERROR: %s" e.Message sr while true do let sr = EstablishConnection() // Read request from the stream. printfn "[F#] Ready to Receive data" sr.ReadLine() |&gt; ParseQuoteString |&gt; RefreshCache printfn "[F#]Quot Size, %d" m_cache.Count let quot = m_cache.["MSFT.OQ"] printfn "[F#]RIC: %s" quot.RicCode printfn "[F#]MadeOn: %s" (String.Format("{0:T}",quot.MadeOn)) printfn "[F#]Price: %f" quot.Price </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.
