Since this is in WPF the obvious richtextbox.find() is not avaliable for use. class TextAnalyser { public int

I'm working with the jQuery Validation plugin and I wrote the following code which adds a class to the element's ( <input> ) parent ( <label> ) if not valid, as well as inserting the actual error element ( <span> ) before the <br> . the HTML ... <label> text<br><input> </label> ... and the jQuery. $("#form_to_validate").validate({ rules: { ... }, errorElement: "span", errorPlacement: function(error, element) { element.parent().addClass('error'); error.insertBefore(element.parent().children("br")); } }); So, if a form element doesn't validate, it turns into: <label class="error"> text<span

The last days I have been trying to implement a highlighting feature in a small text editor. For some reason I get a strange result: The given example should highlight each "dolor" - the first occurences are correctly found and highlighted but the next ones aren't. Here is the code I wrote so far: import java.awt.Color; import java.awt.Dimension; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTextPane; import javax.swing.text.BadLocationException; import javax.swing.text.DefaultHighlighter;

I'm looking for a way of highlighting the days in between the date range of 2 inputs on mouse over. This example is nearly doing what I want to achieve: http://hackingon.net/files/jquery_datepicker/range.htm Only difference is that the highlighting of the selected range should happen on two separate datepickers and on mouse over. Any suggestions? Update: Ok, a bit more details: After selecting a date from the first datepicker, the second datepicker should highlight the previous selected date. If you then mouse over a day past the previous selected day, all days in between should highlight by

(defun annotate-todo () "put fringe marker on TODO: lines in the curent buffer" (interactive) (save-excursion (goto-char (point-min)) (while (re-search-forward "TODO:" nil t) (let ((overlay (make-overlay (- (point) 5) (point)))) (overlay-put overlay 'before-string (propertize "A" 'display '(left-fringe right-triangle)))))))

The ListView items layout is basically a TextView . I mean, the ListView will be a list of TextView 's. What I want is to highlight the search term wherever it appears in the TextView .
