How can I set text, which I read from file, into a multiline CEdit?

You can use SetWindowText(...) to place data into your control.

A couple points of interest:

* Convert your text file line-feeds ("\n") to carriage-return line-feed
pairs ("\r\n").
* Take a look a CEdit::SetSel() for controlling concatenation and text
selection

Note: Spam-resistant e-mail address

The text must contain "\r\n" for line breaks.  Call SetWindowText to the CEdit.

Use ReplaceSel("More text \r\n") if you want to add new lines to the bottom
of the CEdit, rather than overwriting whatever is already there.
