Question

How can one pass http get or post methods to a windows application? I require a webserver to send a get method to my windows form application that will query a database then reply back to a webserver

I’m developing a windows based search engine that searches a MySQL database. It receives a keyword from an SMS gateway software as a HTTP get request and should reply to the gateway software using the same HTTP request.This is my code. It is correctly searching the database but I don’t know how to receive the get methods on the application however it’s sending the messages to SMS gateway.

Private Sub bSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bSend.Click
    Dim request As HttpWebRequest
    Dim response As HttpWebResponse = Nothing
    Dim url As String
    Dim username As String = "admin"
    Dim password As String = "abc123"
    Dim host As String = "http://127.0.0.1:9501"
    Dim originator As String = "0724116972"

    Try

        url = host + "/api?action=sendmessage&" _
                 & "username=" & HttpUtility.UrlEncode(username) _
                 & "&password=" + HttpUtility.UrlEncode(password) _
                 & "&recipient=" + HttpUtility.UrlEncode(tbReceiver.Text) _
                 & "&messagetype=SMS:TEXT" _
                 & "&messagedata=" + HttpUtility.UrlEncode(tbMessage.Text) _
                 & "&originator=" + HttpUtility.UrlEncode(originator) _
                 & "&serviceprovider=" _
                 & "&responseformat=html"


        request = DirectCast(WebRequest.Create(url), HttpWebRequest)

        response = DirectCast(request.GetResponse(), HttpWebResponse)

        MessageBox.Show("Response: " & response.StatusDescription)

    Catch ex As Exception
        MessageBox.Show("Error. Server Not running")
        Me.Close()
    End Try
  End Sub
End Class

sounds like you want to host a webserver in your winforms application…you can use HttpListener – see http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx

IF your application is not running as Administrator you will need to register the URL you are listerning to with netsh though
