Wufoo and REST API

Wufoo (http://www.wufoo.com/) is a great service for creating user forms and getting input. Build a form interactively, let people fill it out, and Wufoo collects the results. If you haven't checked it out before, I highly recommend this great service.

I was simply parsing the emails when they were sent upon form completion but that is a real hassle due to HTML. However, Wufoo has a really good REST API so I started playing around with it. Here, in C#, is how I used their API to get my data. This can easily be converted into SAS as well:

The HttpGet:

internal static string HttpGet(string uri, string apiKey)
{
    var pairs = new StringBuilder();
    var req = WebRequest.Create(uri) as HttpWebRequest;
    req.Timeout = 300000;
    req.Credentials = new NetworkCredential(apiKey, string.Empty);
    req.UserAgent = "AlanC";
    req.ContentType = "text/html";
    req.Method = "GET";

    // Get response

    using (var response = req.GetResponse() as HttpWebResponse)
    {
        if (response != null)
        {
            WebResponse resp = req.GetResponse();
            if (resp != null)
            {
                var sr = new StreamReader(resp.GetResponseStream());
                return sr.ReadToEnd().Trim();
            }
            return null;
        }
    }
    return null;
}

The call to the method:

XDocument xd = XDocument.Parse(HttpGet(@"https://xxxxxxx.wufoo.com/api/v3/forms/xxxxx3/entries.xml", "XXXX-XXXX-XXXX-XXXX"));

The https://xxxxx would correspond to your domain on wufoo.
The xxxxx after forms in the uri would be the form id assigned by Wufoo.
The XXX-XXXX-etc. is the API Key assigned by Wufoo.

The above can be found on the Wufoo site. Just look at the Wufoo API information to find out how to obtain it.

SAS Transport Files and .NET

Well, someone contacted me about the Data Management Utilities. they loved them (thank you) but wanted to know about reading SAS Transport Files. Well, after fiddling with the localProvider a bit and getting nowhere, I stumbled onto something cool:

• Download and install the SAS Universal Viewer from the SAS support site
• Create a new project in Visual Studio
• Add a reference from the SAS Universal Viewer install files to the following 2 dlls
•    SAS.UV.Transport
•    SAS.UV.Utility
• Use the following C# code (adapt as needed):

TransportFile tf = new TransportFile(@"x:\temp\sample.xpt");
var x = tf.Datasets;

Your dataset will be in variable x

UPDATED: 11/8/2017

[NOTE: I have also created a direct reader for the XPT binary format. That took a long time (a week, maybe). Contact me if you need that]

Complete code:

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.OleDb;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SAS.UV.Transport;

namespace ReadSasXportFiles
{
    class Program
    {

        static void Main(string[] args)
        {
            var tf = new TransportFile(@"x:\temp\shoes.xpt");
            var x = tf.Datasets;

         }

     }

}

IMPORTANT NOTE: Make sure your build is set for x64 and not Any CPU. You will see a warning:

Warning There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "SAS.UV.Transport", "AMD64".

RegexBuddy and Automated Emails

So, I am going to help out with a computer club at my kids middle school. Since a topic was needed to start it all off, I said 'hey! regular expressions are used everywhere, why not start there. Plus, it is very useful.'.

So, I sent JGSoft (the owner of RegexBuddy) an email and explained the situation. How they were kids, we needed a limited version or a free one for a certain time, the kids may purchase it after the class, etc.

What was the response?

"We indeed do not offer a free trial version of RegexBuddy for download on our web site. At RegexBuddy's low price point and with our solid 3-month money-back guarantee, you can buy the full version of RegexBuddy entirely risk-free."

All of the supportive messages for RegexBuddy on SAS-L and other places and the best they can do is some automated response saying all of the kids need to cough up the 40 dollars to use their product. This is a fine way to get a bad reputation IMO.

Now I need to go get a free regex editor to show the kids despite RegexBuddy being the premiere product on the market. I am trying to turn them into kids interested in the product so they can go home and dazzle mom and dad who will then pay the fee.

Ok, off of my soapbox.
