[2005] Why? (Replace text problem)

[ovanwijk]

I am making/remaking a mail program i wrote quite some time ago.
It directly inserted HTML on the place it was needed what made quite a mess inside the textbox.

Now i wanna do this afterwards to replace things like [-B] TEXT [-/B] with html code so it wont mess up my text.
How ever i wanna do this with 'enters' too but that is where the problem starts.

If i put this code on the keyPressed event then it works all fine(remember Keys.ENTER is equel to 13(enum code)):

 If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Enter) Then
            Console.WriteLine("enterpressed")
        End If

It shows inside the output when i press enter.

BUT BUT BUT when i try to search to those 'enters' i just cant find them.
This is the code i have:

For Each s As Char In txtRich.Text.ToCharArray

            If s = ChrW(Keys.Enter) Then
                Console.WriteLine("Enter found")

            End If


        Next

it just dont find it.
And i have no idea why :S.

I made it work with comparing the hashcode(after printing the hashcode of the enter char to the output and copy it) but with that cant preform replacements in a string like this:

contentToSend = txtRich.Text.Replace(ChrW(13), "<br>")

Wich obviously dont work either.
(on all code samples i tried the normal chr(13) too.)

I hope someone can come with a solution and maybe wanna tell why i cant do this .

You can't search for a Keyboard key as a character. Look for Environment.NewLine instead.

[ovanwijk]

I tried :

txtRich.Text.Replace(Environment.NewLine, "<br>")

wich still doenst work.

PS i work with a rich textbox but i guess this should not make a difference to the .text property

Try searching for vbNewLine instead of "<br>"

[ovanwijk]

I wasnt looking for "<br>" but replacing with.
vbNewLine doenst work either when i place it on the same place as Environment.NewLine.

Why don't you use Strings.Replace$?

[ovanwijk]

I am useing that.
the property .text is a string

Environment.NewLine is a String that contains a standard line break for the current enviroment. On a Windows system that is a carriage return ('\r', Chr(13), ControlChars.Cr) and a line feed ('\n', Chr(10), ControlChars.Lf). If your text doesn't contain those characters then your replacement won't work. These days Windows also understands just line feeds on their own, which is the standard line break on Unix-based systems. Have you checked what your text actually contains? If Environment.NewLine isn't working then it's likely that your text contains Unix line breaks, so try replacing ControlChars.Lf instead.

Also, it would be more correct to replace with the XHTML-compliant "<br />".

Thnx jmcil ControlChars.Lf (or chrw(10)) works .

Use ControlChars.Lf.
