Dear Friends,
I want to search and highlight the text in pdf. In my window application i will show the pdf in webbrowser control.using acrobat, webbrowser control shows the pdf. based on the values in textbox i need to search and highlight the text. i have tried by passing in url. the below mentioned code searched the word.

i had been gone though adobe document and i was came to know that there is a option to highlight the text based on co-ordinates.

For eg.,highlight lt,rt,top,bottom

but if i passed it in url means it can't highlight. if you have any idea on this?

Dim filename As String
            Dim value As String
            filename = RTBHeadLine.Text
            filename = WebBrowser1.Url.ToString()
            If filename <> "" Then
                value = HttpUtility.UrlEncode(RTBHeadLine.Text.Normalize)
                value = value.Replace("+", " ")
                Me.Text = filename & "#search=" & """" & value & """"
                WebBrowser1.Navigate(filename & "#search=" & """" & value & """")
            End If
