Replacing Text without changing case??

RE: Replacing Text without changing case??

This code works great, but case has to be exact.

Research.Text = Research.Text.R eplace(textboxS earch.Text, "<b>" +
textboxSearch.T ext + "</b>")



I found some c# code, but I can't make it work in vb.net:

Regex.Replace(R esearch.Text, textboxSearch.T ext, New
MatchEvaluator( HiLite), RegexOptions.Ig noreCase)


....
Public Shared Function HiLite(ByVal match As Match) As String
Return "<b>" + match.Value + "</b>*"
End Function


Its complaining about Hilite in the first line.

Re: Replacing Text without changing case??

THANK YOU!

Regex.Replace(s tring.format("( {0})", Regex.Escape(in put)), "<b>$1</b>", RegexOptions.Ig noreCase)

Presuming

user search input : textboxSearch.t ext
replace is : "<b>"+textboxSe arch.text+"</b>"
data I'm looking to impact is : Research.Text (a gridview row label
control)


How would I use the above?

I tried:

Imports System.Text.Reg ularExpressions

Research.Text = Regex.Replace(S tring.Format("( {0})",
Regex.Escape(te xtboxSearch.Tex t)), "<b>$1</b>",
RegexOptions.Ig noreCase)


Getting an error on Regex.Replace : Reference to a non-shared member
requires an object reference.

So I noticed it appears to be formated incorrectly and probably should
be :

Research.Text = Regex.Replace(S tring.Format("( {0})"),
Regex.Escape(te xtboxSearch.Tex t), "<b>$1</b>",
RegexOptions.Ig noreCase)

However that did not work.

I also tried:


No effect:
Research.Text = Regex.Replace(S tring.Format("( {0})"),
Regex.Escape(te xtboxSearch.Tex t), "<b>$1</b>",
RegexOptions.Ig noreCase)


replaces string with actually "$1":
'Research.Text = Regex.Replace(R esearch.Text,
Regex.Escape(te xtboxSearch.Tex t), "<b>$1</b>",
RegexOptions.Ig noreCase)


works, in finding the strings, but replaces with wrong case:
'Research.Text = Regex.Replace(R esearch.Text,
Regex.Escape(te xtboxSearch.Tex t), "<b>"+ textboxSearch.T ext+"</b>",
RegexOptions.Ig noreCase)



Thanks again.

Sorry, I mixed the input and the pattern parameters to the Regex.Replace
function.

This should do it (in C#, I'm no star in VB):

string input = "a.b.c.d.e.f.g. h.i.j";
string output = Regex.Replace(i nput, string.Format(" ({0})", Regex.Escape(in put)),
"<b>$1</b>");
Console.WriteLi ne(output);

Re: Replacing Text without changing case??

I'm close, but this ends up highighting all of research.text when a
match is found. How can I highlight just the found string in it's
original case?

Research.Text = Regex.Replace(R esearch.Text, String.Format(" ({0})",
Regex.Escape(Re search.Text)), "<FONT style='backgrou nd-color:Yellow'>
$1</FONT>")

thanks.

That shouldn't be too hard, but currently you're puttign the whole string
in for both input and pattern.

Research.Text = Regex.Replace(

Research.Text, <== input
String.Format(" ({0})", Regex.Escape(Re search.Text)), <== text to search
"<FONT style='backgrou nd-color:Yellow'>$ 1</FONT>" <== replacement
)

So make sure you only put the text to search in the correct place.
