First things first: you need to show your dialog (using myFindWhatForm.ShowDialog) and then fetch the text to search for using a property of the dialog form to return it.

Then you can use string.IndexOf[^] to locate the first instance of the string in the Text property of the TextBox.
When you have the index, that's the first character you want to highlight, and the length of the search text is the number of characters to highlight.

Highlighting is easy:
C#
int index = myEditTextBox.Text.IndexOf(searchForText);
if (index >=0)
    {
    myEditTextBox.SelectionStart = index;
    myEditTextBox.SelectionLength = searchForText.Length;
    myEditTextBox.Focus();
    }
If you don't set the focus to the textbox, you probably wont see the highlight - it'll be focussed on the "Find" button.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
