Hello,

You can determine a number of pages and the index of the current page only

after the document is formatted for printing (TRVPrint.FormatPages is

called). And on any change in the document this page formatting information

becomes invalid.

I am afraid it's not possible to display a number of pages and the current

page in the status bar, because it would require updating page information

on each change. Of course, you can call RVPrint.FormatPages in

RichViewEdit.OnChange, but it would be very slow.

However, printing the current page is possible. After calling

RVPrint.FormatPages, you can use RVPrint.GetFirstItemOnPage and compare it

with RichViewEdit.CurItemNo and OffsetInCurItem.

It's more tricky if your application uses tables, but I can explain how to

get a number of the current page in this case, if you need.
