Access hidden dynamic Property in COM-object with C#

I need to access a specific property inside a COM object (the iTunes COM Library). You can access this property with the dynamic view of the Visual Studio debugger.
I tried to get this property using Reflection but I don't get any private properties or fields back.
I can access all the Properties that I also see in the debugger using this line:
new Microsoft.CSharp.RuntimeBinder.DynamicMetaObjectProviderDebugView(myObject).Items
However, I would rather not use this call because I believe an easier solution exists.
If you have iTunes installed this would be a simple example of what I'm trying to achieve:
iTunesAppClass app;
if (Process.GetProcessesByName("iTunes").Any())
{
app = new iTunesAppClass();
}
else
{
return;
}
foreach (IITPlaylist playlist in app.LibrarySource.Playlists)
{
// This does not work. There is no "Parent".
//var parent = playlist.Parent;
Type playListType = playlist.GetType();
// both contain 0 results
var fields = playListType.GetFields(BindingFlags.NonPublic);
var properties = playListType.GetFields(BindingFlags.NonPublic);
// works but only during runtime
//var parent2 = new Microsoft.CSharp.RuntimeBinder.DynamicMetaObjectProviderDebugView(playlist).Items[4];
}

When I load data form my DB it says "Path contains an empty part", how should I adjust the code?

I can loop out every table from my DB except this particular one for some reason. When I launch my app it crashed immediatly with this error "Path contains an empty part" as I am initializing my "retrieve-the-data" function directly. So this is how I loop it out, I get the results in the log just fine.
foreach (var currentItem in getItems["results"]) {
theName = currentItem ["name"].ToString ();
}
and then I have tried to solve it by doing something like this:
if (Path != null) { //when I try to solve it like this then I get the error: System.IO.Path is a type but a variable was expected.
//i work with pins and the pins are alrdy added just fine. it is just this code below that is the issue.
pin.SetBinding (Label.TextProperty, new Binding (theName));
pin.BindingContext = theName;
//this is where I get the error/crash. if I write my own text, for example "test" instead it runs and also if i do pin.Label = theName; So the setbinding/bindingcontext does not seem to like the data iam trying to connect it with.
}
when I loop out the results in the log I get every item perfectly fine so i reach the data I retrieve the data and the info I am receiving is standard text, with "", dots, etc.
When i google the matter and the issue in particular "Path contains an empty part" i see no previous threads. So I am very confused right now.
This is how I retrieve the data via httprequests:
static public async Task<JObject> getInfo ()
{
var httpClientRequest = new HttpClient ();
var result = await httpClientRequest.GetAsync ("localhost");
var resultString = await result.Content.ReadAsStringAsync ();
var jsonResult = JObject.Parse (resultString);
return jsonResult;
}

How do I programatically change the status of a test in VersionOne?

I am posting this because it might help someone using the VersionOne API SDK Client. I wanted to change the status of a test programmatically, to one of the following categories: Ready, InTesting, Passed, or Failed. I originally tried to change the attribute 'Status.Name' however I would get an error that the attribute is a Read-Only attribute. Another suggestion was to create a new attribute with the same name and that the new attribute would override the previous read-only attribute with the same name. However, it appears that I was looking at it backwards.
internal void TestStatusPassed(string str_TestID)
{
var testId = Oid.FromToken(str_TestID, _context.MetaModel);
var query = new Query(testId);
var testType = _context.MetaModel.GetAssetType("Test");
var sourceAttribute = testType.GetAttributeDefinition("Status.Name");
query.Selection.Add(sourceAttribute);
var result = _context.Services.Retrieve(query);
var test = result.Assets[0];
var oldSource = GetValue(test.GetAttribute(sourceAttribute).Value);
test.SetAttributeValue(sourceAttribute, "Passed");
_context.Services.Save(test);
}
This code will throw an exception "Cannot change a read-only attribute"...

I pulled the XML data for one test from the VersionOne Rest API and noticed a relation named "TestStatus" and then it had a number '9123' assigned to it. So I moved that test manually to 'In Testing' and the "TestStatus" changed to '9121'. Then I moved it to failed and the "TestStatus" changed to '155'. I repeated this with several tests from different testsets and noticed that the numbers for each status were consistent and then changed the code slightly and then I was able to programmatically change the status of each test. I changed "Status.Name" to "Status" and "Passed" to "TestStatus:9123" and now it moves the test into the passed category programmatically.
internal void TestStatusPassed(string str_TestID)
{
var testId = Oid.FromToken(str_TestID, _context.MetaModel);
var query = new Query(testId);
var testType = _context.MetaModel.GetAssetType("Test");
var sourceAttribute = testType.GetAttributeDefinition("Status");
query.Selection.Add(sourceAttribute);
var result = _context.Services.Retrieve(query);
var test = result.Assets[0];
var oldSource = GetValue(test.GetAttribute(sourceAttribute).Value);
test.SetAttributeValue(sourceAttribute, "TestStatus:9123");
_context.Services.Save(test);
}

NullReferenceException when deleting a sitecore items children

i'm trying to import some legacy poll data into our sitecore solution. For part of the import, i'm trying to create new sitecore items to hold the data based off of a master page we already have set up for polls. this master has a couple of default items set up underneath of it, and I want to delete a couple of specific default items before I add the legacy poll data. however, when i attempt to delete one of the default items using item.DeleteChildren(), i get a NullReferenceException thrown by Sitecore.Tasks.ItemEventHandler.OnItemDeleted(Object sender, EventArgs args) in the sitecore kernel. if anyone has any idea what could be causing this, i'd appreciate it. we're on sitecore version 5.3.2.
here is the code i'm using to attempt to create/edit the item based off of a master. the creation all works perfectly, it's the DeleteChildren() call that doesn't work.
Guid LegacyPollFolderGuid = new Guid("8AE89A44-9DCD-4AC2-B0F3-DD438188A575");
Guid QuizOMaticMasterGuid = new Guid("74B95ABF-1898-4870-8B4F-50AF0078AE22");
var master = Sitecore.Configuration.Factory.GetDatabase("master");
var root = master.GetItem(new Sitecore.Data.ID(LegacyPollFolderGuid));
var quizMasterTemplate = master.Masters[new Sitecore.Data.ID(QuizOMaticMasterGuid)];
var quizPage = root.Add("Test Quiz", quizMasterTemplate);
if (quizPage != null)
{
var quiz = quizPage.Children["Column One"].Children["QuizOMatic"];
if (quiz != null)
{
var questionFolder = quiz.Children["Questions"];
var questionTemplate = questionFolder.Children[0].Template;
var resultsFolder = quiz.Children["Results"];
var linksFolder = quiz.Children["Links"];
using (new Sitecore.SecurityModel.SecurityDisabler())
{
questionFolder.DeleteChildren();
}
}

I've built a tool with the same functionality; removing all items under a specific folder. I got the same error, but I saw items being deleted. So I reran the tool multiple times and eventually all items were deleted.

Sharepoint Client Object Model setting ModifiedBy field

I am trying to update the "ModifiedBy" field in a Sharepoint discussion board using the Client Object Model. By changing the "Editor" and "Author" fields, I can change the "ModifiedBy" that appears on the list view. However, once you click on a discussion post, the "ModifiedBy" field that appears there (the one with the picture above it) does not reflect the changes. After experimenting, I discovered that the field I need to change to correct this is called "MyEditor". Unfortunately, this field is read-only.
In the code below, I try to change the read-only settings of the field to false. When I look at the MyEditor field in Visual Studio's debugger after the ExecuteQuery() line at the bottom of the first block, it shows that the ReadOnlyField value has in fact been set to false.
sharepointContext.Load(discussionList);
sharepointContext.ExecuteQuery();
var fields = discussionList.Fields;
sharepointContext.Load(fields);
sharepointContext.ExecuteQuery();
var field = fields.GetByInternalNameOrTitle("MyEditor");
field.ReadOnlyField = false;
field.Update();
sharepointContext.Load(field);
sharepointContext.ExecuteQuery();
The code above executes with no problems. The problem comes with this next block:
//...Code to initialize discussionItem...
discussionItem["MyEditor"] = 0;
discussionItem["Editor"] = 0;
discussionItem["Author"] = 0;
discussionItem["Body"] = "Testing";
discussionItem["Title"] = "Hello Worlds";
discussionItem.Update();
sharepointContext.Load(discussionItem);
sharepointContext.ExecuteQuery();
When the code reaches the ExecuteQuery() at the bottom of the second block, it throws a ServerException with the following message:
Invalid data has been used to update the list item.
The field you are trying to update may be read only.
To make sure that the MyEditor field was the one causing the exception to be thrown, I commented out the line where I set it and ran the code again. Everything worked fine. I don't understand what is wrong, can someone help me?

In case someone needs to find the user by name, it goes like this:
private static FieldUserValue GetUser(ClientContext clientContext, string userName)
{
var userValue = new FieldUserValue();
var newUser = clientContext.Web.EnsureUser(userName);
clientContext.Load(newUser);
clientContext.ExecuteQuery();
userValue.LookupId = newUser.Id;
return userValue;
}
The returned value can be set via item["Author"]

ModifiedBy and CreadtedBy calculated automatically from Author and Editor you need to change only Author and Editor fields like this:
using (var clientContext = new ClientContext(#"http://server"))
{
var web = clientContext.Web;
var lst = web.Lists.GetByTitle("Discus");
var item = lst.GetItemById(2);
item["Author"] = 3;
item["Editor"] = 2;
item.Update();
clientContext.ExecuteQuery();
Console.WriteLine("done");
}
