TPrintDialog.MaxPage Property

Determines the greatest page number the user can enter when specifying pages to print.

Pascal

property MaxPage: Integer;

C++

__property int MaxPage;

Description

If the user tries to enter a number greater than MaxPage, an error message appears.

Note: The user can specify page numbers only if the poPageNums flag is set in Options. If poPageNums is on, MaxPage must be set to a value greater than MinPage or the Print dialog will not open.

C++ Examples:

{
This example uses a button, a Page Control, and a Print 
dialog box on a form. When the user clicks the button, the 
print dialog is displayed.  The user can select any subset 
of the pages in the page control for printing.  The selected
pages are then printed.  To run this example successfully, 
you must add the Printers unit to the uses clause of your 
unit.  Right click on the PageControl to add at least one 
page to the PageControl.
