    <p>The way this file works is there is a null buffer, then a user check sum then a byte that gives you the user name letter count, then a byte for how many bytes to skip to the next user and a byte for which user file the user keeps their settings in.</p> <p>the loop with the usersm variable in the IF statement sets up the whole file stream for extraction. However with almost the exact same code the else clause specifically the str.Read(xnl, 0, usn - 1) in the else code appears to be reading the very beginning of the file despite the position of the filestream being set earlier, anyone know whats happening here?</p> <p>this is in vb2005</p> <pre><code>Private Sub readusersdata(ByVal userdatafile As String) ListView1.BeginUpdate() ListView1.Items.Clear() Using snxl As IO.Stream = IO.File.Open(userdatafile, IO.FileMode.Open) Using str As New IO.StreamReader(snxl) str.BaseStream.Position = 4 Dim usersm As Integer = str.BaseStream.ReadByte() Dim users As Integer = usersm While users &gt; 0 If usersm = users Then Dim trailtouser As Integer = 0 str.BaseStream.Position = 6 Dim ust As Integer = str.BaseStream.ReadByte() str.BaseStream.Position = 8 Dim snb(ust - 1) As Char str.ReadBlock(snb, 0, ust) Dim bst = New String(snb) If usersm = 1 Then str.BaseStream.Position = 16 Else str.BaseStream.Position = 15 End If cLVN(ListView1, bst, str.BaseStream.ReadByte) str.BaseStream.Position = 8 + snb.Length str.BaseStream.Position += str.BaseStream.ReadByte + 1 Else Dim usn As Integer = str.BaseStream.ReadByte str.BaseStream.Position += 2 Dim chrpos As Integer = str.BaseStream.Position Dim xnl(usn - 1) As Char str.Read(xnl, 0, usn - 1) Dim skpbyte As Integer = str.BaseStream.ReadByte str.BaseStream.Position += 3 Dim udata As Integer = str.BaseStream.ReadByte End If users -= 1 End While End Using End Using ListView1.EndUpdate() End Sub </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
