Creating Custom Print Previews

The PrintPreviewControl control displays print previews, and you can use it to create your own custom print preview windows—all you have to do is to assign a print document to its Document property (and have at least implemented the print document's PrintPage event handler). I've added a second form, Form2, to the Printing example on the CD-ROM to show how to create a custom print preview, and placed a print preview control, PrintPreviewControl1, in that form (and also added a Close button that closes the form). Here's what the code to launch the custom preview looks like in the Printing example:

Private Sub MenuItem4_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MenuItem4.Click
    Dim preview As New Form2()
    preview.PrintPreviewControl1.Document = PrintDocument1
    preview.Show()
End Sub

You can see the custom print preview dialog in the Printing example in Figure 9.9.
