Search for words and change their color

Coding · 03-21-2008, 06:25 PM

If you have a richTextBox that contains these words.
What is the best/good way to do, if I want to change the color of the word "hello" to Ex: red.
Is there any searchfunction that can select multiple words etc...
I am trying to find a way to do this.

one two three hello
five hello
hello

I have a complete mind block on the actual code, but know the process... (!)

Put all the richTextBox contents in to a string, replace search term in string with the word itself and the formatting needed.

ie. (but not actually this! This example replaces the term wanted with a bolded word in html format)

Code:

public static void ReplaceText(string myTerm)
{
  string myString = richTextBox1.Text;
  myString.Replace(myTerm, "<b>"+myTerm+"<\b>");
  richTextBox1.Text = myString;
}

Then you can just feed in whatever term you want ("hello") like so:

Code:

ReplaceText("hello");

I'm bored, needed to do something random...
