    <p>I believe this does what you want. It's in C# because I'm not set up to test VB, but you shouldn't have any trouble converting it.</p> <pre><code>Regex r = new Regex( @"^(?&lt;FIELD&gt;[^\s:;]+)(;(?&lt;PARAM&gt;[^;:]+))*:(?&lt;CONTENT&gt;.*(?&gt;\r\n[ \t].*)*)$", RegexOptions.ExplicitCapture | RegexOptions.Multiline); string target = @"TEL;WORK;VOICE:0200 0000000"; Match m = r.Match(target); if (m.Success) { Console.WriteLine("field name: {0}", m.Groups["FIELD"].Value); foreach (Capture c in m.Groups["PARAM"].Captures) { Console.WriteLine(" type: {0}", c.Value); } Console.WriteLine("content: {0}", m.Groups["CONTENT"].Value); } </code></pre> <p>EDIT: Now that I know <a href="http://blog.smithfamily.dk/CategoryView,category,vcard.aspx" rel="nofollow noreferrer">where you got the regex from</a>, I can see the author is trying to do too much work in the regex. "Encoding" and "charset" are just two of many possible parameter names; I don't see any reason to match those two by name and not any others. Just iterate through the "PARAM" captures like I did and handle each one as appropriate.</p> <p>The author also allows for line folding, which probably <em>does</em> belong in the regex. The rules governing line folding seem pretty simple: if a line starts with a space or a tab, it's a continuation of the previous line. That also means the "FIELD" subexpression needs to be revised to disallow whitespace as well as colons and semicolons. </p> <p>I've revised my regex and added the Multiline modifier, which should have been there all along. :-/</p> <p>I feel I should mention that, if you're writing a complete vCard processing app, you probably shouldn't be building it on top of regexes. A non-regex solution will be easier to write (though not as much fun) and easier to maintain.</p>

    1. COI got the Regular Expression from here : http://blog.smithfamily.dk/CategoryView,category,vcard.aspx, it was the only example that was not tied to the fieldnames themselves.

    3. COOkay, thanks. I was editing the answer when you did that, and SO didn't notify me. I still think my way is better, but if you're happy...

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.
