Problems casting an ComObject in VB.net

I have a Word.Field object which is a checkbox and the Type property equals wdFieldFormCheckBox. I am trying to cast the Word.Field object as Word.CheckBox object but I am getting casting errors.

Dim chkBox as Word.CheckBox
chkBox = DirectCast( myFieldInstance, Word.Checkbox)

How do I cast a Word.Field object into Word.CheckBox object?

From stackoverflow

• Hi,

  this is not possible. CheckBox is a property of a FormField object and not a field object.
