Removing superstition with brute force - 5 fridays, saturdays and sundays in a month

Came across the following Facebook status update and thought it would be a simple thing to prove wrong.

I'm not superstitious, but this year July has 5 Fridays, 5 Saturdays and 5 Sundays.
This happens once every 823 years.

Or the alternative version:

Money bags

This year, July has 5 Fridays, 5 Saturdays and 5 Sundays. This happens
once every 823 years. This is called money bags. So, forward this to
your friends and money will arrive within 4 days. Based on Chinese
Feng Shui. The one who does not forward.....will be without money. 

  static void Main(string[] args)
  {
   int occuranceCount = 0;

   // Change to suit month of interest (1 to 12)
   int monthToTest = 10;

   for (int year = 1; year <= 2011; year++)
   {
    int fridayCount = 0;
    int saturdayCount = 0;
    int sundayCount = 0;

    for (int dayOfMonth = 1; dayOfMonth <= DateTime.DaysInMonth(year, monthToTest); dayOfMonth++)
    {
     DateTime dateToTest = new DateTime(year, monthToTest, dayOfMonth);
     if (dateToTest.DayOfWeek == DayOfWeek.Friday) { fridayCount++; }
     if (dateToTest.DayOfWeek == DayOfWeek.Saturday) { saturdayCount++; }
     if (dateToTest.DayOfWeek == DayOfWeek.Sunday) { sundayCount++; }
    }

    if (fridayCount == 5 && saturdayCount == 5 && sundayCount == 5)
    {
     occuranceCount++;
     Console.WriteLine(occuranceCount + " " + year);
    }

    
   }
   Console.ReadLine();
  }

This is the only time you see this phenomenon in your life.

Calendar August 2014  
 
August, next year, will have 5 Fridays, 5 Saturdays and 5 Sundays.  This happens only once every 823 years.  The Chinese call it 'Silver pockets full.  " So: send this message to your friends and in four days money will surprise you.  Based on Chinese Feng Shui.  Whoever does not transmit the message ... may find themselves poor
 
I obeyed (you never know).

Sending a Sitecore MediaStream through a HttpResponse

The following code can be used to stream Sitecore media back to the client without using the configured MediaRequestHandler.

 public class MediaDownload
 {
  public static void ProcessRequest(Page page, Media media)
  {
   Assert.ArgumentNotNull(page, "page");
   Assert.ArgumentNotNull(media, "media");
   if (!DoProcessRequest(page, media))
   {
    page.Response.StatusCode = 404;
    page.Response.ContentType = "text/html";
   }
  }

  private static bool DoProcessRequest(Page page, Media media)
  {
   Assert.ArgumentNotNull(page, "page");
   Assert.ArgumentNotNull(media, "media");
   
   if (media != null)
   {
    return DoProcessRequestToStream(page, media);
   }

   return false;
  }

  private static bool DoProcessRequestToStream(Page page, Sitecore.Resources.Media.Media media)
  {
   Assert.ArgumentNotNull(page, "context");
   Assert.ArgumentNotNull(media, "media");
   if (Modified(page, media) == Tristate.False)
   {
    SendMediaHeaders(media, page);
    page.Response.StatusCode = 304;
    return true;
   }
   MediaStream stream = media.GetStream();
   if (stream == null)

  private static Tristate Modified(Page page, Sitecore.Resources.Media.Media media)
  {
   DateTime time;
   string ifNoneMatch = page.Request.Headers["If-None-Match"];
   if (!string.IsNullOrEmpty(ifNoneMatch))
   {
    return Tristate.True;
   }
   string ifModifiedSince = page.Request.Headers["If-Modified-Since"];
   if (!string.IsNullOrEmpty(ifModifiedSince) && DateTime.TryParse(ifModifiedSince, out time))
   {
    return MainUtil.GetTristate(time != media.MediaData.Updated);

Using a DllImport referenced DLL indirectly from a TestTools.UnitTesting.TestClass

Project A uses DllImport to invoke code in a third party DLL. Project B uses Microsoft.VisualStudio.TestTools.UnitTesting to run some test cases on Project A.

The automated tests in project B were failing as the DLL required by project A wasn't being copied into the TestResults directory used by the tests.

Adding the DeploymentItem attribute to the test classes in Project B with the path to the DLL revolved the issue.

Invoking a public Salesforce Web Service Method from a force.com site

Typically when dealing with a Salesforce hosted web service you need to first authenticate to the login site to get a sessionId and Url of the server that will process the requests.

It turns out that it is possible to invoke a web service without this authentication step provided it is configured in a certain way.

Step 1

Mark the class as global and the web service as public. E.g.

 /* 
 * Test to see if the web service can be connected to and used 
 * without having to log in as there is no api sObject use here.
 */
global class HelloWorld
{
    WebService public static String GetMessage()
    {
        return 'Hello world';
    }
}

Step 2

In Salesforce, it is important to give public access to the class (Adding the class under Settings > Develop > Sites > Public Access Settings)

Step 3

Download and import the WSDL from the Apex class.

Step 4

Once you have imported the WSDL you will need to use the public URL of the web service rather than the standard version which requires a session to be established first.

E.g. The domain will change to use the a pattern like:

https://<yourcompanyinsites>.<sandboxname>.<sandbo​xinstance>.force.com/<sitename>

https://<yourcompanyinsites>.secure.force.com/<sitename>

Step n+1

One of the key aspects when calling it from C# is setting ServicePointManager.Expect100Continue before creating the web service proxy. E.g.

System.Net.ServicePointManager.Expect100Continue = false;

IIS terminated web server process during debugging - Application poll ping settings in IIS

When debugging a web application from Visual Studio I've started getting the following error when I take too long to step through a process:

"The web server process that was being debugged has been terminated by Internet Information Services (IIS). This can be avoided by configuring Application Pool ping setting in IIS. See help for further details."

Try increasing the "Ping Maximum Response Time (seconds)" or turning off "Ping Enabled" entirely.

Sitecore CMS 6.2 - Accessing parameters in Sublayouts

<Rant>I often seem to have no end of grief when searching for Sitecore documentation straight from Google. It seems most of the useful information is buried in cookbooks and component references which are in PDF format rather than HTML and require a login to the Sitecore Developer Network. I just find it frustrating that they have lots of good documentation but it is difficult to search. I'm almost tempted to bring all their docs down to a public facing web server and letting it get indexed.</Rant>

As a case and point, I wanted an administrator editing the layout details for a content items control to be able to specify a value that would be mapped into a public property on a user control. The Additional Parameters seemed like a good candidate but didn't lead anywhere with the standard Sitecore install.

Turning to Google I found Anders Dreyers post on Accessing parameters in Sublayouts with Sitecore 5.3.1. At least with that version of Sitecore it looked like parameters weren't easily available in a sublayout.

That post did lead me to Sitecore.Web.UI.SublayoutRenderingType, which is referenced in the web.config as the rendering control for sublayouts. Using Reflector on it shows that the parameters collection could be used to automatically set properties using reflection.

After searching through the Presentation Component Reference I went to the Presentation Component Cookbook PDF via a footnote reference and then onto the SublayoutParameterHelper via another footnote.

4.5.3 How to Pass Rendering Parameters to a Control
To pass parameters to a control using the Control Properties dialog:

• In the Control Properties dialog, enter control properties.

To pass parameters to a control using the rendering properties dialog:

• In the rendering properties dialog, click the Parameters tab, and then enter named parameters.¹²

¹² To access the parameters passed to a sublayout, see http://trac.sitecore.net/SublayoutParameterHelper.

Googling for SublayoutParameterHelper lead me back to Cascade the Data Source of a Sublayout down to Nested Controls PDF, which seems to explain how to use the SublayoutParameterHelper.

This looks like just what I was after. By inheriting from Sitecore.Sharedsource.Web.UI.Sublayouts.SublayoutBase rather than System.Web.UI.UserControl the parameters will be automatically mapped to the corresponding properties in the sublayout if they exist. Just remember to call base.OnInit() if you override it (as per the documentation).

ASP.NET Control.SetRenderMethodDelegate()

I was looking for a way to inject a WebControl as the next sibling of another HtmlControl where they may not be in a control tree yet. The post Adding Rendering with SetRenderMethodDelegate() - aeh, sort of seemed like a possibility but didn't eventuate as certain controls (Panels) would render their outer content before passing off the the rendering delegate.
