So I am currently writing an application that takes in user criteria and searches through a webpage for links and then returns them. The application woks just fine if you only want to search once... I cannot figure out how to reset the attributes of the website I am linked to via WebBrowser Control. I set the textfields of the connected website when I click the search button by using
wbCraigsList.Document.GetElementById("query").SetAttribute("value", searchDescription)
but then when i go to search again, the user's criteria is different but it doesn't change the WebBrowser control's attributes. For example, if i originally search "ford" in the description on my app and click search it fills in the craigslist search box with "ford" and searches. If I go to change "ford" to "chevy" on my app the WebBrowser control does not change the craigslist textfield and still searches ford.

 'set the craigslist text fields to the user's criteria
    Private Sub setUserSearchCriteria(desc As String, min As String, max As String)
        wbCraigsList.Document.GetElementById("query").SetAttribute("value", desc)
        wbCraigsList.Document.All.GetElementsByName("minAsk")(0).SetAttribute("value", min)
        wbCraigsList.Document.All.GetElementsByName("maxAsk")(0).SetAttribute("value", max)
    End Sub

    Private Sub clearSearch()
        txtSearch.Text = Nothing
        txtMinPrice.Text = Nothing
        txtMaxPrice.Text = Nothing
    End Sub

    'Starts the search process through Craigslist
    Private Sub btnSearch_Click(sender As Object, e As EventArgs) Handles btnSearch.Click
            MessageBox.Show("Search Description: " + searchDescription)
            wbCraigsList.Document.GetElementById("query").SetAttribute("value", searchDescription)
            wbCraigsList.Document.All.GetElementsByName("minAsk")(0).SetAttribute("value", searchMinPrice)
            wbCraigsList.Document.All.GetElementsByName("maxAsk")(0).SetAttribute("value", searchMaxPrice)


            numResults = wbCraigsList.Document.GetElementsByTagName("a").Count

            'create an elements collection to store the links of the search results
            Dim resultsCollection As HtmlElementCollection
            resultsCollection = wbCraigsList.Document.GetElementsByTagName("a")


            For i As Integer = 0 To numResults Step 1
                Results.txtResults.AppendText("Test" + vbLf)
        Catch ex As Exception
        End Try

        searchDescription = ""
    End Sub

    Private Sub btnClear_Click(sender As Object, e As EventArgs) Handles btnClear.Click
    End Sub
Please let me know if you need clarification on anything. Thanks, any help would be awesome!
