    <p>I used to change the Form shape in VB 6.0 using the following code:</p> <pre><code>Private Declare Function CreateRoundRectRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long, ByVal X3 As Long, ByVal Y3 As Long) As Long Private Declare Function SetWindowRgn Lib "user32" (ByVal hWnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long Private Sub MakeRoundObject(objObject As Object, Value As Long) Static lngHeight, lngLong, lngReturn, lngWidth As Long lngWidth = objObject.Width / Screen.TwipsPerPixelX lngHeight = objObject.Height / Screen.TwipsPerPixelY SetWindowRgn objObject.hWnd, CreateRoundRectRgn(10, 50, lngWidth, lngHeight, Value + 10, Value), True End Sub Private Sub Form_Load() Call MakeRoundObject(Form1, 50) End Sub </code></pre> <p>In the same way I used VB.NET code as follows:</p> <pre><code>Imports Microsoft.VisualBasic.Compatibility Public Class Form1 Private Declare Function CreateRoundRectRgn Lib "gdi32" (ByVal X1 As Integer, ByVal Y1 As Integer, ByVal X2 As Integer, ByVal Y2 As Integer, ByVal X3 As Integer, ByVal Y3 As Integer) As Integer Private Declare Function ReleaseCapture Lib "user32" () As Integer Private Declare Function SetWindowRgn Lib "user32" (ByVal hWnd As Integer, ByVal hRgn As Integer, ByVal bRedraw As Boolean) As Integer Private Sub MakeRoundObject(ByRef objObject As Object, ByRef Value As Integer) Static lngLong, lngHeight, lngReturn As Object Static lngWidth As Integer lngWidth = objObject.Width / VB6.TwipsPerPixelX lngHeight = objObject.Height / VB6.TwipsPerPixelY SetWindowRgn(objObject.hWnd, CreateRoundRectRgn(0, 0, lngWidth, lngHeight, Value, Value), True) End Sub Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load MakeRoundObject(Me, 20) End Sub End Class </code></pre> <p>But in the latter case, I receive an error message - "Public member 'hWnd' on type 'Form1' not found."</p> <p>What I do?</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.
