How to print selected text of richtextbox?

[rfresh737]

Here is my code to print a richtextbox file.

But I have two problems:

1. It doesn't print any text. Just blank paper comes out of my printer.

2. I'd like to be able to optionally select text to print as an option. I've enabled that in my printDialog component.

Thanks for any help.

            PrintDocument printDoc = new PrintDocument();
            printDoc.DocumentName = mFullPathFileName;
            printDialog.Document = printDoc;
            DialogResult result = printDialog.ShowDialog();
            if (result == DialogResult.OK)
            {
                printDoc.Print();
            }

Your code prints a blank pages because you are telling it to print a blank page (i.e. your printDoc variable is initialized to a default class which doesn't know what to print).

You need to override PrintPageEventHandler as shown in the msdn PrintDocument class.

Scroll down in the link for an example where a txt file is read by a StreamReader (the variable's name is streamToPrint) and this stream is printed in the pd_printPage event handler.

Your code would implement the same event handler, but it would use the text from the richeditcntl (or the selected text of the control).

I would recommend that you code up the sample using the txt file approach and get it to print the file and then modify the sample to print the contents of a richeditctrl.
