'\\n' is printed inseted of new line

Answer 1

As for web pages, break lines with <br> or <p></p> tags. You can also Use Environment.NewLine with VB.

For JS use \\n' for the line break -

 alert("some text\\nmore text in a new line"); 

Answer 2

Not a vb expert, but shouldn't it be "\\n" instead of "'\\n'"? The one in the vb code have both double and single.

Answer 3

Please try with Environment.NewLine for VB.net

as below:

Dim value As String = "[First" + _
        Environment.NewLine + _
        "Second]"

will return

[First
Second]
