In a project using a RichTextBox, when I copy text and paste it into some other applications, the line breaks are missing. This happens in MS NotePad and the sample text area in Expresso. The text pastes correctly (line breaks are present) with WordPad, NoteTab Lite and NotePad++.

Here's the code used to copy text (RichTextBox is named "rtf"):

Private Sub menuEdit_Copy_Click(ByVal sender As Object, ByVal e As EventArgs) Handles menuEdit_Copy.Click, tb_Copy.Click, popup_Copy.Click
Try
If rtf.SelectedText.Length > 0 Then
Clipboard.SetText(rtf.SelectedText, TextDataFormat.Text)
End If
Catch ex As Exception
MsgBox(ex.ToString, MsgBoxStyle.Exclamation, title)
End Try
End Sub

Any ideas why this happens?

That makes some sense. RichTextBox is very unusual among Windows controls. Its line endings are "\n", every other code in Windows uses "\r\n". Although I don't repro, there's a good chance that some controls don't handle "\n" well. If SetText() is preferred, you can probably fix the problem with Replace("\n", "\r\n").

All of them or just the last one? What version of Windows?

Looks like using RichTextBox.Copy() instead of ClipBoard.SetText() solves the problem. I was told by a member over at CodeProject that RichTextBox.Copy() deals properly with newline chrs, while ClipBoard.SetText() doesn't always provide the receiving application the info it needs to recognize the ends of the lines.
