  hi,

  to find and replace in richtextbox you use the text property

  to repalce you do something like this

  rt.Text.Replace("oldvalue","newvalue");

  to find you may use something like this

  string value = "something";

  int start = rt.Text.IndexOf(value );

  rt.Select(start, value.Length);

  hope this helps

  Hi I couldn't understand your reaction to that code. I mean if I need to find or replace don't I need a box to do like microsoft word have or I don't think I understand how does it work, since I am somehow new to C#.

  thanks jbattat

  Hi Mr. Shakalama, I created a search form called searchForm and i am trying to use that as find and replace and serach, with this code :

  private void findToolStripMenuItem_Click(object sender, EventArgs e)

  {

  searchForm searchForm = new searchForm();

  richTextBoxPrintCtrl1.Find(searchForm.Show);

  searchForm.Show();

  }

  I am getting an error:

  Error 1 The best overloaded method match for 'System.Windows.Forms.RichTextBox.Find(string)' has some invalid arguments .

  hi,

  i don't think exposing your form controls outsideof the form is a good thing, and you cant do it the way you did you can use constractors to do this, to add a constractor to your form that take a string and you write the find part in the search form you will instantiate the searchform like this

  SearchForm sf = new SearchForm("text to find");

  hope this helps

  You might want to look into regular expressions provided in System.Text.RegularExpressions.
