I can create an array of text boxes but adding tb.dodragdrop does not make them drag and drop. what do I need to add when they are created?

This is a partial list of code so far which doesn't allow dropping image names from the image files:

VB

Dim TextCtrl(13) As TextBox
Dim xLoc1 As Integer = 10
Dim yLoc1 As Integer = 30
'-----Add textboxes as arrays
For count1 As Integer = 0 To 13
    Dim tb As New TextBox
    tb.Location = New Point(xLoc1, yLoc1)
    tb.Name = "TextCtrl"
    tb.DoDragDrop()
    Me.Controls.Add(tb)
    TextCtrl(count1) = tb '<-- This line adds the TextBox to the array.
    TextCtrl(count1).AllowDrop = True
    TextCtrl(count1).DoDragDrop(e, DragDropEffects.All)

    yLoc1 += 25
Next count1

You need to add handlers to your TextBox to handle the critical DragAndDrop events: DragEnter and DragDrop: this shows how to add handlers: http://msdn.microsoft.com/en-us/library/ms743596(v=vs.110).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-2[^]
The DragEnter handler needs to check if the data source is compatible, and set the Effect property appropriately, and the DragDrop handler needs to action the drop.
This may also help: http://msdn.microsoft.com/en-us/library/aa289508(v=vs.71).aspx[^]

Without the two handlers correctly implemented, nothing will happen.
