The following code example assumes the form contains a TreeView
object named TreeView1 that contains TreeNode objects. Each 
TreeNode object’s Tag property must be set to a fully-qualified
document name that can be accessed by the machine running the 
example.  Set each Text property to a string that identifies 
the file specified by the Tag property. For example, you could set 
TreeNode1.Tag to  “c:\myDocuments\recipe.doc” and 
TreeNode1.Text to “recipe.doc”.

It also assumes the form contains a PrintPreviewDialog object 
named PrintPreviewDialog1 and a button named Button1. To run this 
example call the InitializePrintPreviewDialog method in the form's 
constructor.
