Example

[Visual Basic 6.0]

This Visual Basic 6.0 example creates an InkOverlay object and allows the user to alternately ink, select, and delete the ink by setting the EditingMode property, while reporting details on the SelectionMoved, SelectionMoving, SelectionResized, SelectionResizing, StrokesDeleted and StrokesDeleting events within a text box. This application starts with a standard .exe application and adds a reference to Microsoft Tablet PC Type Library, a Picture control, Picture1, a command button, Command1, and a text box, Text1, then adds the following code to the form.

Option Explicit
Private WithEvents theInkOverlay As InkOverlay

Private Sub Command1_Click()
    'Set the EditingMode to the next of
    'the options with each click of the
    'button.

        'This is hard to do unless you are using
        'multiple cursors at once.
        Text1.Text = "Can't switch while collecting ink"
    ElseIf theInkOverlay.EditingMode = IOEM_Ink Then
        theInkOverlay.EditingMode = IOEM_Select
        Command1.Caption = "Select"
    ElseIf theInkOverlay.EditingMode = IOEM_Select Then
        theInkOverlay.EditingMode = IOEM_Delete
        Command1.Caption = "Delete"
