Hi Rolf, In my software I print invoice, lists, whatever..... When I print invoices I print the lines with a function which calculates where it has to print on the page:
Public Sub PrintAt(Row As Float, Col As Integer, Txt As String) txtWidth = Draw.Font.TextWidth(txt) txtHeight = Draw.Font.TextHeight(txt) PosY = Row * 162 posX = Col * 55 + 50 Paint.DrawRichText(Txt, PosX, PosY, txtWidth, txtHeight) End Now I want to skip to the next page when variable Row exceeds a value. But somehow I cannot find how I can skip to the next page. So what I am realy looking for is the addpage function which was available in gambas 2. Whe I fiddled arount in my code by telling there were 2 pages, the content on page 2 was nog cleared, e.g. it was the same as on page 1. Any ideas?
