Close Document Preview

[gestrato]

Good morning everyone,
I'm working with VPE Professional edition V6 and i am having some difficulty to close document preview.
I Tryed (With ExternalWindow True or False):
VPE.OpenDoc()
VPE.DefineKey(23, Keys.Escape, 0, 0)
VPE.Preview()

When the document get opened, button ESC and any closing button doesn't worked.
I appreciate some help. Thanks in advance.

my developer environment is Visual studio VB.Net

Lima.
