Hello,
I'm having newby difficulties printing from a richtextbox to a printer.
I have built a small application (Like part of notepad) with file load and print.
I can load file or write to the textbox, but when printing (using the PrintDialog to select and set the printer) I always get an empty page from the default printer.
Can someone show me how to make this printing and print previw work? (See attched code).
Why do I always get my default printer, even when selecting another network printer?
