I wish to implement this script:

http://sellonline.canadapost.ca/DevelopersResources/HTMLReturn/HTTP_Post_Sample_With_ASP.asp

It is the live quote example script from Canada Post.

I'm trying to find the point that would be best to start this implementation at but I know so little about ASP.NET specifically (let alone ASP) that I could really use a hand.

Has anybody done anything similiar?  Is this easier / harder than it seems (it seems like it should be quite easy)?

Cheers!

Edit:  Just to expand on what I have done up to now:

Installed the VB Pro from MS.  Installed the previous version of DNN for development as per Gilles' posts.  Ensured my hierarchy is in order and have been Googling since.
I'm currently thinking I have to create an entirely new provider as was mentioned in a thread below, but if possible I wish to place this as the default shipping method and simply have the weight calculation take place if the live quote times out or otherwise fails.

I'll post as I progress.

So I've got this code chunk :

using System.IO; //Used for Stream Writer

using
System.Net; //Used for webResponse

 
//Page level vars
protected string strCPXMLRequest = "";

private const string strCPRetailerID = " PUT YOUR CANADA POST ID HERE";

private const string strCP_PostURL = "http://sellonline.canadapost.ca:30000";

protected void Page_Load(object sender, EventArgs e)

{

//Build CP XML

// This will eventually become dynamic from the products ordered

strCPXMLRequest = " <?xml version='1.0' ?> ";

strCPXMLRequest += "<eparcel> ";

strCPXMLRequest += "<language> en </language> ";

strCPXMLRequest += "<ratesAndServicesRequest> ";

strCPXMLRequest += " <merchantCPCID> " + strCPRetailerID + " </merchantCPCID> ";

strCPXMLRequest += " <lineItems> ";

strCPXMLRequest += " <item> ";

strCPXMLRequest += " <quantity> 1 </quantity> ";

strCPXMLRequest += " <weight> 1.5 </weight> ";

strCPXMLRequest += " <length> 1 </length> ";

strCPXMLRequest += " <width> 1 </width> ";

strCPXMLRequest += " <height> 1 </height> ";

strCPXMLRequest += " <description> My Sample Item</description> ";

strCPXMLRequest += " </item> ";

strCPXMLRequest += " </lineItems> ";

strCPXMLRequest += " <city> </city> ";

strCPXMLRequest += " <provOrState> Wisconsin </provOrState> ";

strCPXMLRequest += " <country> CANADA </country> ";

strCPXMLRequest += " <postalCode> H3K1E5 </postalCode> ";

strCPXMLRequest += "</ratesAndServicesRequest> ";

strCPXMLRequest += "</eparcel>";

HttpWebResponse webResponse;

try

{

HttpWebRequest webRequest = WebRequest.Create(strCP_PostURL) as HttpWebRequest;

// 10 secs

webRequest.Timeout = 10000;

//Method

webRequest.Method = "POST";

// Content type

webRequest.ContentType = "text/xml";

// Wrap the request stream with a text-based writer

StreamWriter swXMLPost = new StreamWriter(webRequest.GetRequestStream());

// Write the XML text into the stream

swXMLPost.WriteLine(strCPXMLRequest);

swXMLPost.Close();

swXMLPost = null;

// Send the data to the webserver

webResponse = webRequest.GetResponse() as HttpWebResponse;

if (!webRequest.HaveResponse || (webResponse.StatusCode != HttpStatusCode.OK && webResponse.StatusCode != HttpStatusCode.Accepted))

{

//Must do somehting here there is an error with the canada post responce etc.

}

StreamReader srCPResponse = new StreamReader(webResponse.GetResponseStream());

string strCPResponse = srCPResponse.ReadToEnd();

srCPResponse.Close();

srCPResponse = null;

Response.Write(strCPResponse);  //Test the server response, IE does not like to display the xml.

//Must run error check for "ERROR_CODE" in XML at this point and do something if present

}

catch

{

//Do something with the error here

}

}
 

It is a direct translation of the ASP script shown above.

I'm searching through the source code, and am having a difficult time locating where to start plugging bits in.

Steady as she goes.

Thanks very much for your help, Giles.  Keep up the great work!
