Installation

1. Copy the files PRNTPREV.DCU, PRNTPREV.DCR, *.DFM, and *.RES to your
   DELPHI\LIB directory.
2. From the "Options" Menu, select "Install Components".  Press the "Add"
   button, and then the "Browse" button.  Go to the LIB directory, and
   select UNIT file types (*.dcu).  Then select PRNTPREV.DCU and press "OK".
   Then press "OK" for the Install Components dialog box.
3. When Delphi is done compiling there will be a new component in your
   "Samples" palette called PrintPreview.

Testing the Print Preview Component

A sample project is already provided.  Open the project called TESTPREV.DPR
and run it.  Note:  you must install the Print Preview component before
opening and running the test project.

When the program starts, you are given four page tab control (Text, Table,
Graphics, and MultiPage).  Select each page and press the Print Preview
button to view the demo.  You may change some of the options for each of the
examples.

Once inside the Print Preview screen, you can zoom in or out (with the
buttons or by clicking with the mouse).  The Hand tool can be used to move
the page around (only if it is larger than the screen).  You can select a
one page or two page view.  In the MultiPage example, you can advance to
the next page, or move back.

Advanced

To use the Print Preview component in your own projects, simply drop the
component on your form.  Then register the three events (Begin Print, End
Print, and Print Page) with your own routines.  Refer to the Test project
sample code, or to the PRNTPREV.INT file for technical details on
interfacing with the component.  The sample project code shows 90% of what
can be done with the component.


Shareware Registration

This component is shareware, and is distributed to be used for a limited
trial period of 30 days.  You are free to copy and distribute this software
in unmodified form.  After the 30 day period the software should be
registered or removed from the user's system.  If the component is to be
included in a commercial or government application, it must be registered
(i.e., paid for).

The registered version of the component offers two additional benefits:
1) the ability to hide the "About" box on the Preview screen, or replacing
it with your own custom button & procedure; and 2) technical support via
email or phone (you pay the long distance though).  Source code is also
available to registered users.


Pricing and Ordering Information

Registered Print Preview is U.S. $20.  Full source code is an additional
$20.  If you need a 3.5" disk mailed to you, an additional $4 is charged for
shipping and handling.  Preferrable, if you have email I can just email you
the registered component (and source code).
