    Re: Find a string in a webpage

    Put a webbrowser control on your page.

    YOu can navigate to the desired page by calling the Navigate method:
    vb Code:
    1. WebBrowser1.Navigate "http://www.mywebsite.com"

    You can get the InnerText and see if it contains what you want:
    vb Code:
    1. Dim PageText As String
    2. Dim SearchText as String
    3. SearchText = "glasgow rangers"
    4. PageText = WebBrowser1.Document.Body.InnerText
    5. If InStr(PageString, SearchText) > 0 Then
    6.     Msgbox "Found"
    7. Else
    8.     MsgBox "Not Found"
    9. End If

    NB: None of the above code is tested. I just typed it here, so it might have spelling mistakes too. The sole intention was to make you understand how to go about it. Please let me know if something doesn't work.
