    <p>Ok I got this code from Gemster from <a href="http://tech.reboot.pro/showthread.php?tid=2982" rel="nofollow">http://tech.reboot.pro/showthread.php?tid=2982</a>. So I just looked for something to plug into my system as it need to be done asap. So I copied and pasted. However, I do understand what is going on. The only problem is that it skips over a section of important code and I can't figure out why. So here it is.</p> <pre><code> Dim CurrentVersion As String = My.Application.Info.Version.ToString '--- Change this to Current version, needs changing on every update Dim ProgramName As String = My.Application.Info.AssemblyName '--- Change this to Your Program Name Dim SiteName As String = "http://somewebsite.com/UpdateVersion.html" '--- Change this to Your Update page Dim VersionCHK As String = "" Dim GetVer As String = "" Dim GetVerLink As String = "" Dim GetUpd As Integer 'Web Request Dim WebRequest As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(SiteName) Dim WebResponse As System.Net.HttpWebResponse = WebRequest.GetResponse Dim STR As System.IO.StreamReader = New System.IO.StreamReader(WebResponse.GetResponseStream()) Dim ReadSource As String = Str.ReadToEnd Dim Regex As New System.Text.RegularExpressions.Regex(ProgramName &amp; "=(\d+).(\d+)=(.*?).zip") Dim matches As MatchCollection = Regex.Matches(ReadSource) </code></pre> <p>This is the part that it skips the 'Split String' for each statement</p> <pre><code> 'Split String For Each match As Match In matches Dim RegSplit() As String = Split(Match.ToString, "=") GetVer = RegSplit(1) GetVerLink = RegSplit(2) Next </code></pre> <p>This is where it picks back up.</p> <pre><code> 'Check Verison If GetVer &gt; CurrentVersion Then GetUpd = MsgBox(ProgramName &amp; " is an old version." &amp; vbCrLf &amp; "New Update is available" &amp; _ vbCrLf &amp; "Current version: " &amp; CurrentVersion &amp; vbCrLf &amp; "Version Avalible: " &amp; _ GetVer &amp; vbCrLf &amp; vbCrLf &amp; "Update Now?", vbYesNo, "Update") If GetUpd = vbYes Then Dim sfd As New SaveFileDialog sfd.FileName = IO.Path.GetFileName(GetVerLink) If sfd.ShowDialog = DialogResult.OK Then My.Computer.Network.DownloadFile(GetVerLink, sfd.FileName) End If End If Else MsgBox(ProgramName &amp; " is upto date." &amp; vbCrLf &amp; "Current version: " &amp; CurrentVersion, 0, "Update") End If Return vbNull </code></pre> <p>Any ideas why? Thanks in advance. </p>

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.
