thanks luo I have done it in this way Public Function Highlight( ByVal InputTxt As String ) As String Dim i As Integer Dim Search_Str As String = key Dim arr_color As String () Dim highlight_str As String =  highlight_str = InputTxt arr_color = Search_Str.Split(   ) For i = 0 To UBound(arr_color) ' Setup the regular expression and add the Or operator. Dim RegExp As Regex = New Regex((arr_color(i).Trim()).Replace(     ).Trim() RegexOptions.IgnoreCase) ' Highlight keywords by calling the MatchEvaluator delegate each time a keyword is found. highlight_str = RegExp.Replace(highlight_str New MatchEvaluator( AddressOf ReplaceKeyWords)) ' Set the Regex to nothing. RegExp = Nothing Next Highlight = highlight_str End Function Public Function ReplaceKeyWords( ByVal m As Match) As String Return   & m.Value &   End Function and it's working
