Yahoo Widget Engine (ex-Konfabulator)
Recently I've found the Yahoo Widget Engine quite useful for odd widgets.
Below are some widgets that I have made for personal use and you may find useful.
Please note that there is no guarantee that they'll work perfectly ...
Widgets are usually developed for XP however some are suitable for OSX as well.
Widget downloads are HERE
UPDATE:
YWE is now a legacy coding app since Yahoo abandoned it years ago however for the hobbyist it is still a very effective
tool for making desktop widgets and mini applications. The manual for the latest version (4.5.2) is excellent and because it essentially used web
technologies it will still function on newer OSes.

VB 2005 stuff
Odd stuff encountered whilst using VB 2005 Express.
Simple solution for drag and dropping a single item within the same listbox.
This was found at
http://vbforums.com/showthread.php?t=492618 posted by a chap called
Rykler. MSDN and elsewhere have more complex variations but this works
fine for the simple requirement within a listbox. Initially it didn't
work for me - the item would drag with the appropriate mouse effect but
the DragDrop wasn't occurring when the DragOver was ended. Of course it
turned out to be a silly error by myself - the old DragDrop Sub was
renamed but I didn't rename the handle so the DragOver was ending and
using the old DragDrop handle to go into hyperspace!
eg:
Private Sub listbox1Renamed_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles listbox1.DragDrop
Should have been - Handles listbox1Renamed.DragDrop
Good Code -
Click mouse to select item -
Private Sub listbox1_MouseDown(ByVal sender As Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles listbox1.MouseDown
listbox1.DoDragDrop(listbox1.Text, DragDropEffects.All)
End Sub
Drag item holding mouse down -
Private Sub listbox1_DragOver(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles listbox1.DragOver
e.Effect = DragDropEffects.Move
End Sub
Release mouse button to drop -
Private Sub listbox1_DragDrop(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles listbox1.DragDrop
' Drops before item that pointer is over
listbox1.Items.Insert(listbox1.IndexFromPoint(listbox1.PointToClient(New
Point(e.X, e.Y))), e.Data.GetData(DataFormats.Text))
listbox1.Items.RemoveAt(listbox1.SelectedIndex)
listbox1.Refresh() ' not strictly required
End Sub
