Welcome to my blog about the software tools / techniques I have used.

The first posts, were originally hosted in a variety of places,  &  I thought it would be nice to bring them all together.   Its mainly a journal of  some of the things I have worked on, that might be useful to me in the future.  If it helps anyone else, then great.

I have been developing Web Applications with Domino / Lotus Notes since the 90s, mainly in areas where workflow & security are important. Before that I worked on financial systems with Foxpro, Oracle & PL/1.

In parallel with Domino, recently I have focused more on C# .NET, Sharepoint, JQuery , Javascript, CSS  & HTML5 .




I wanted to write a SOAP consumer for SOAP UI XML using WebAPI2.0, because WCF wasn’t playing nicely.  I needed  to process SOAP in the following format (in this case from SOAPUI):

<soapenv:Envelope xmlns:soapenv="" xmlns:tem="">
    <wsse:Security soapenv:mustUnderstand="0" xmlns:wsse="" xmlns:wsu="">
    <wsse:UsernameToken wsu:Id="UsernameToken-93E8DFC2DBD6AF2C5115005561877993">
    <wsse:Password Type="">passwordtext</wsse:Password>
    <wsse:Nonce EncodingType="">nWFUtDng50qtbALaZ+/Q4w==</wsse:Nonce>
   <Field1>gero et</Field1>  
   <Field2>sonoras imperio</Field2>  
   <Field3>quae divum incedo</Field3>  
   <Field4>verrantque per auras</Field4>

Notice this has a Wsse Basic Auth credential in the header, & a simple XML Body.

Step 1 I built a standard WebApi2.0 project  (mine was called SoapService).

Step 2 I created a C# class for uploadData (the XML Node within the Body above).  My first attempt at this (with a more complex data model) used the raw SOAPUI XML with Visual Studio’s  Edit / Paste Special / Paste XML as Classes. 9 times out of 10 this works brilliantly. Today, the deserialize only parsed half the data I needed, & left many of the body’s  sub classes as null, giving no error message.  Instead,  I manually built a  simpler class matching the precise node,  I wanted to work on (uploadData):

 public class uploadData
  public string Field1 { get; set; }
  public string Field2 { get; set; }
  public string Field3 { get; set; }
  public string Field4 { get; set; }

Step 3 The basic POST function of the WebAPi’s SoapServiceController  takes in a string & echoes it back to you. I tweaked it as follows:

  1. Changed the input type from string to HttpRequest message, so you can get everything that is being posted, headers & all.
  2. Got the actual posted data with value.Content.ReadAsStringAsync().Result
  3. Loaded that to an XMLDocument, to manipulate the content programmatically
  4. Got the security header into a XMLNodeList with .GetElementsByTagName();
  5. Parsed the security header elements into some other elements.
  6. Loaded the uploadData XML into another XMLNodeList & built a c# uploadData object  from it.
public string Post(HttpRequestMessage value)
 { //2
  var posteddata = value.Content.ReadAsStringAsync().Result;
  XmlDocument xmldoc = new XmlDocument();
  XmlNodeList UserNameToken = xmldoc.GetElementsByTagName("wsse:UsernameToken");
  string uid = "";
  string pw="";
  string nonce="";
  XmlNamespaceManager ns = new XmlNamespaceManager(xmldoc.NameTable);
  ns.AddNamespace("wsse", "");
  foreach (XmlNode item in UserNameToken)
   uid = item.SelectSingleNode("wsse:Username",ns).InnerText;
   pw = item.SelectSingleNode("wsse:Password",ns).InnerText;
   nonce = item.SelectSingleNode("wsse:Nonce",ns).InnerText;
 XmlNodeList elemList = xmldoc.GetElementsByTagName("tem:uploadData");
 string f1 = "";
 string f2="";

foreach (XmlNode P in elemList)
  f1 = P.SelectSingleNode("Field1").InnerText;
  f2 = P.SelectSingleNode("Field2").InnerText;
 uploadData UD = new uploadData {
  Field1= f1,
  Field2= f2,
return "success";


Simple Kerberos Feature Detect in JQuery

Simple jquery $.ajax on a remote service.  In the restful web API  AppAuthorize is a custom .NET Filter that takes in a role as a parameter & returns True or False as to whether the current user is a member of that role.  It extends the WEB API 2.0 Authorise functionality from System.Web.Http.AuthorizeAttribute.

The AuthChk function is Authorised for people with the “READERS” role

GenericLibrary.SQLHandler is a custom class, comprising

  •  public int returncode { get; set; }
  • public string Message { get; set; }
 public GenericLibrary.SQLHandler AuthChk( string callback = "")
 GenericLibrary.SQLHandler retval = new GenericLibrary.SQLHandler();
 {// Is there a valid credential
var usercred = System.Web.HttpContext.Current.User.Identity.Name;
 if (usercred != null)
  retval.returncode = 0;
  retval.Message = "API Authentication = " + usercred;
  retval.returncode = -1;
  retval.Message = "Error accessing credential in API";
 catch (Exception ex)
 retval.returncode = -1;
 retval.Message = "API Credential Error : " + ex.Message; 
 return retval;

Then  in the document.ready function

var KrbResultCheck = "Error";
 $(document).ready(function () {
 var KerbCheckurl = "api/myApp/AuthChk";
toastr.options = {.....  config  toastr settings
 url: KerbCheckurl,
 contentType: 'application/json; charset=utf-8',
 type: 'GET',
 async: false,
 dataType: 'json',
 success: function (data) {
// If the service works then overwrite KrbResultCheck
 KrbResultCheck = data;
 error: function (xhr, status, error) { 
 var err = JSON.parse(xhr.responseText);
 toastr.error(" Web Service Authentication Check failed" + err.Message , "ERROR");
 catch (exception)
 toastr.error(" Another Exception " + exception, "ERROR");


if (KrbResultCheck == "Error")
 toastr.error("<br/><br/><br/> Remote Authentication Check executed but did not return correct credential", "ERROR");


Getting all the records from a large SharePoint list with CSOM

I have often had problems getting all the rows from a large Sharepoint list.  Admin limits on the number of rows you can return often cause queries to fail.

The fix for this is to make your query return fewer records using a Where clause in your Caml query.  These can be problematic too as they have eccentric syntax, you don’t always know what data values are actually present in the list, what are the internal fieldnames, or whether the query still fall foul of the Admin limits?

The SharePoint ID field can help.  It’s an internal field that increments automatically to give you a row id.  Its always there, has a different value for each row, & its a simple number – so its perfect for splitting your list into manageable chunks.

To process an entire list, I looked for records whose id was between 1 & 1000, & added them to  a C# list I created in memory (&whose structure matched the SharePoint list).  Then I moved onto to the next chunk and so forth until I was done.

To my knowledge Sharepoint doesnt make available the minimum & maximum list values,  so how did I know when I was done?  You’ll recall I started with id range 1 – 1000, then 1001-2000, Chunk 3 was 2001 to 3000.   If a query returned no records , I incremented a counter of queries that had returned nothing ( called zerocount) by 1.   When this counter reached the arbitrary figure of 700,  I exited the loop.

This helped because in my test the ID field didnt start at 1 (I think it was 38,000o or something like that. This helped us move through the empty ranges until we find ranges that do return records. 

The code below starts with a startkey of 1 & an endkey of 1000 & looks for records whose ids fall in that range.   When its done,  it increments both key values by 1000 ( to give 1001 – 2000) and repeats.  To stop a permanent loop, we stop processing after n  queries have returned nothing, since the last one did actually return data.  To do this, I increment a counter if no data is returned.  Otherwise, I reset the counter to zero.  At some point this counter will reach a point, when I decide there’s probably nothing else to process – so I stop the program.  I set this figure to be 700 – that’s 700 queries & 700,000 ID values searched for and not found in SharePoint, before I decide that there’s probably no more data!  The number of records to process at a time & the number of queries with no rows you accept , is for you to decide.

        { int tval1 = Convert.ToInt32(val1);
            tval1 += val2;
            return tval1.ToString();

These are the app settings from the app config:

    <add key="baseUrl" value="http://mySPurl/" />
    <add key="StartKey" value="1" />
    <add key="EndKey" value="1000" />

& myClass looks like

class myClass
    public string myfield1{ get; set; }
    public string myfield2 { get; set; }

IF I find code to get the maximum & minimum ids I’ll post it here


C# Automated Testing Complex object from Web Service

When your  Assert.AreEqual or CollectionAsser.AreEqual fails inspite of both objects containing the same columns & values, you’ll find a lot of complicated advice about overriding the underlying .Equals code for your classes.

This is a much simpler approach which works with any 1 dimensional object containing many fields.  The code tests a restful web service with many parms

Case Insensitive QueryString in Angular

If your Angular app is expecting a QueryString parameter of myParm1,  &  instead it gets passed MypArM1, then the following command will fail:

var MyParmOne_Value = $ ; 

This JS code ( in the angular controller) deals with that by building a new array from the query_string & forcing every key to lowercase.  This new array is then used to retrieve values instead of the $ object:

var QSarr = [], hash;
var sourceQS = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i <sourceQS.length; i++) {
 hash =sourceQS[i].split('=');
 var key = hash[0].toLowerCase()
 QSarr[key] = hash[1];
//later we want that QueryString value so we search for myparm1 in the array
 var MyParmOne_Value =QSarr["myparm1"];
