how do i change the font color of a String.SubString in a textBox?

  You can't do this in the TextBox control, only in the RichTextBox control.
  
  Use the Select method to select a piece of text and set the color. Then re-select something else and set the color.
  
  

  if( myRichTextBox.TextLenght >= 5 ) { myRichTextBox.Select( 0, 5 ); myRichTextBox.SelectionColor = Color.Green; } if( myRichTextBox.TextLenght >= 15 ) { myRichTextBox.Select( 10, 15 ); myRichTextBox.SelectionColor = Color.Red; }

  thanks i want to use rtf format but i don't know how to extract the plain text from the rtf code and display it in a reportviewer.

  anyway i have decided to use delimeters, "/*" and "*/", how can i find their indices if they're all over the rtb

  You must search the plain text for the tag's. Manipulating RTB yourself is a little bit hard, use a RichTextBox control for this and only use the Text property to read the plain text and change color, fonts and style with the selection methods.

  i got the change color part, here's what i have:

  this.txt.Select(start, len);

  this.txt.SelectionColor = Color.Green;

  now my problem is how can i highlight or select multiple substrings from txt.Text
