    <p>Working on a DragDrop application. I have a class object (built as an object) which has a GroupBox that is enabled for DragDrop.</p> <p>In the class I have set it up so that the cursor will change when it enters the groupbox, leaves the groupbox, mouse is down within the groupbox and drag/drop is working. I also set up a label in the class object and changed the text in that label as well. Basically, the text changes in the label as expected including 'FEEDBACK' appearing when I am dragging the object BUT the cursor stays stubbornly as a pointer. This is tghe state of affairs either when I debug the class or when, after I build the class, it is run as part of the main program.</p> <p>Here are the subs set up in the class.</p> <pre><code>Private Sub GroupBoxSourceMouseDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseDown GroupBoxSource.DoDragDrop(GroupBoxSource.Text, DragDropEffects.Copy) lbl1.Text = "DOWN" End Sub Private Sub GroupBoxSourceMouseMove(ByVal sender As Object, ByVal e AsSystem.Windows.Forms.MouseEventArgs) Handles GroupBoxSource.MouseMove If bolDragDropMouseDown Then ' Initiate dragging. 'GroupBoxSource.DoDragDrop(GroupBoxSource.Text, DragDropEffects.Copy) End If bolDragDropMouseDown = False lbl1.Text = "MOVE" End Sub Private Sub GroupBoxSourceMouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseEnter Windows.Forms.Cursor.Current = Cursors.Hand lbl1.Text = "ENTER" End Sub Private Sub GroupBoxSourceMouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseLeave Windows.Forms.Cursor.Current = Cursors.Arrow lbl1.Text = "LEAVE" End Sub Private Sub GroupBoxSourceDragDropFeedback(ByVal sender As Object, ByVal e As GiveFeedbackEventArgs) Handles GroupBoxSource.GiveFeedback Windows.Forms.Cursor.Current = Cursors.SizeAll lbl1.Text = "FEEDBACK" End Sub </code></pre> <p>Now for the unusual stage. I decided to change the cursor during FormLoad of the main program (which has the class object defined on the form) to a hand and nothing changed. In desperation I set up a 1mS timer and coded that to change the cursor to a hand and sure enough the cursor is now a hand but momentarity flicks back to a pointer when I move the cursor so it looks as if something else is causing the cursor to revert to its default value.</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.
