stringbuilder replace doesn't work on vbLf , vbCrLf , vbCr

[Guy]

Hi,

I'm trying to run this code :

strFileContents HTML.Replace(vb Lf, "<br>")
strFileContents HTML.Replace(vb CrLf, "<br>")
strFileContents HTML.Replace(vb Cr, "<br>")

It doesn't replace newline characters with <br>.

Does anyone know how I should do this?

Thanks,
Guy

'StringBuilder. Replace' /returns/ a reference to a string builder which
contains the final data:

\\\
strFileContents Html = strFileContents Html.Replace(.. .)

Thanks for the repsonse Herfried.
I tried your suggestion and it still doesn work.

I changed the code to :

strFileContents HTML = strFileContents HTML.Replace(vb Lf, "<br>")
strFileContents HTML = strFileContents HTML.Replace(vb CrLf, "<br>")
strFileContents HTML = strFileContents HTML.Replace(vb Cr, "<br>")

Earlier I tested

strFileContents HTML.Replace("a ", "<br>")

and it worked fine. The problem seems to be only with the newline characters.

Guy,

Strange, this test
\\\
Dim strFileContents HTML As New System.Text.Str ingBuilder("Hel lo" & vbLf & _
"how" & vbCrLf & "are" & vbCr & "you")
strFileContents HTML = strFileContents HTML.Replace(vb Lf, "<br>")
strFileContents HTML = strFileContents HTML.Replace(vb CrLf, "<br>")
strFileContents HTML = strFileContents HTML.Replace(vb Cr, "<br>")
Debug.WriteLine (strFileContent sHTML.ToString)
///
Has for me as result.
Hello<br>how<br ><br>are<br>y ou

Be aware that the vbcrlf is of course already done first by the vblf and
will not be done in this way so that has actualy to be done first.

I hope this helps,

Cor

Have you tried using the asci decimal value &#10 or Chr(10) or Chr(13) instead of vbLf
and vbCrLf

The order of your replacements doesn't make much sense. If you are already
replacing 'vbLf' characters with "<br>", the text doesn't contain 'vbCrLf'
character sequences any more. Are you sure the stringbuilder contains the
characters you want to replace?

This line won't work too because you never assign the return value of
'Replace' to a string variable.

Thanks for the response Cor.
That example works for me too.

I think I've found the problem.
I'm populating the string builder w/ :

InputStream.Rea dLine

I assumed this returned everything upto and including endline characters but
apparently it only returns upto and not including the endline characters.

If I manually add my own "<br>" I get the result I'm looking for.

Herfried,
| 'StringBuilder. Replace' /returns/ a reference to a string builder which
| contains the final data:
Correct!

However! it also modifies the StringBuilder itself, and then returns a
reference to "Me".

Making the assignment:

| strFileContents Html = strFileContents Html.Replace(.. .)

unnecessary with StringBuilder as it is returning "Me", which has already
been modified. Unlike String.Replace that returns a new string.

The StringBuilder returns a reference to allow:

strFileContents HTML.Replace(vb Lf, "<br>").Replace (vbCrLf,
"<br>").Replace (vbCr, "<br>")

More commonly I've seen:

strFileContents HTML.Append("He llo
").Append(first Name).Append(Co ntrolChars.NewL ine)

Which allows each "line" to be on a single source line, however I find it
more confusing then simply using a With statement or the original code.

Which enables C# to use:

strFileContents HTML.Append("He llo ")
.Append(firstNa me)
.Append(Control Chars.NewLine);

Which VB.NET does not allow

strFileContents HTML.Append("He llo ") _
.Append(firstNa me) _
.Append(Control Chars.NewLine)

However VB.NET has the With statement to cover the above, which IMHO is
better as it doesn't require the type's methods to return the "Me/this"
reference...

Hope this helps
Jay

Thank you for making me aware of that. When I was pressing the "Send"
button I was almost sure that I missed something because I could not believe
that a new 'StringBuilder' is created when performing a simple replace
operation :-/.
