     For those who want to create their own text editor and want to move text around with drag and drop just like MS Word does.

				'Add a richtextbox control in ur form

Dim sel1, sel2 as Integer

Sub Richtextbox1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Richtextbox1.MouseDown
If Richtextbox1.SelectedText <> "" And e.Clicks <> 2 Then
sel1 = Richtextbox1.SelectionStart
sel2 = Richtextbox1.SelectionLength
Richtextbox1.DoDragDrop(Richtextbox1.SelectedRtf, DragDropEffects.Move)
End If
End Sub

Private Sub Richtextbox1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Richtextbox1.DragEnter
e.Effect = DragDropEffects.Move
End Sub

Private Sub Richtextbox1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Richtextbox1.DragDrop
If Richtextbox1.SelectionStart < sel1 Then
Dim selStart As Int16 = Richtextbox1.SelectionStart
Richtextbox1.SelectedRtf = e.Data.GetData(DataFormats.Text).ToString()
Richtextbox1.SelectionStart = sel1 + sel2
Richtextbox1.SelectionLength = sel2
Richtextbox1.SelectedText = ""
Richtextbox1.SelectionStart = selStart
End If
If Richtextbox1.SelectionStart > sel1 + sel2 Then
Richtextbox1.SelectedRtf = e.Data.GetData(DataFormats.Text).ToString()
Richtextbox1.SelectionStart = sel1
Richtextbox1.SelectionLength = sel2
Richtextbox1.SelectedText = ""
End If
End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
RichTextBox1.AllowDrop = True
End Sub
