Creating a folder under Inbox using Mocrosoft.Graph 2.0.14

I'm trying to create a folder under my Inbox in Office 365 using MS Graph 2.0, but I'm finding surprisingly little information on the topic anywhere on the internet. The authentication works fine, and I was able to read the existing test folder. My method for doing this is below:
private void SetupMailBoxes()
{
SmartLog.EnterMethod("SetupMailBoxes()");
MailFolder inbox = null;
try
{
bool dbErrorFolder = false;
bool exchangeErrorFolder = false;
inbox = _journalMailbox.MailFolders.Inbox.Request().GetAsync().GetAwaiter().GetResult();
if (inbox.ChildFolderCount > 0)
{
inbox.ChildFolders = _journalMailbox.MailFolders.Inbox.ChildFolders.Request().GetAsync().GetAwaiter().GetResult();
}
if (inbox.ChildFolders != null)
{
for (int i = 0; i < inbox.ChildFolders.Count && (!dbErrorFolder || !exchangeErrorFolder); i++)
{
if (inbox.ChildFolders[i].DisplayName.ToLower() == "db-error-items")
{
dbErrorFolder = true;
}
else if (inbox.ChildFolders[i].DisplayName.ToLower() == "exchange-error-items")
{
exchangeErrorFolder = true;
}
}
}
if (!dbErrorFolder)
{
try
{
//inbox.ODataType = "post";
var folder = _journalMailbox.MailFolders.Inbox.Request().CreateAsync(
new MailFolder()
{
DisplayName = "DB-Error_Items",
}).GetAwaiter().GetResult();
//inbox.ChildFolders.Add(folder);
}
catch (Exception ex)
{
throw;
}
}
}
catch (Exception exp)
{
SmartLog.LeaveMethod("SetupMailBoxes()");
throw;
}
finally
{
}
SmartLog.LeaveMethod("SetupMailBoxes()");
}
Where _clientSecretCredential is created like this:
_graphServiceClient = null;
_options = new TokenCredentialOptions { AuthorityHost = AzureAuthorityHosts.AzurePublicCloud };
_clientSecretCredential = new ClientSecretCredential(
this.FindString(config.TenentID)
, this.FindString(config.AppID)
, this.FindString(config.Secret)
, _options);
string[] apiScope = new string[] { this.FindString(config.Scope) };
_token = _clientSecretCredential.GetToken(new Azure.Core.TokenRequestContext(apiScope));
graphServiceClient = new GraphServiceClient(_clientSecretCredential, apiScope);
IUserRequestBuilder _journalMailbox = _graphServiceClient.Users["journal#mycompany.com"];
The code seems correct, but everytime I execute "_journalMailbox.MailFolders.Inbox.Request().CreateAsync", I get the following error:
Code: ErrorInvalidRequest
Message: The OData request is not supported.
ClientRequestId:Some Guid.
From what I could figure out by searching on the internet, it has to do with the method using the wrong method to access the API. I mean like, its using "GET" in stead of "POST" or something like that, but that would mean its a bug in the MS code, and that would an unimaginably big oversight on Microsoft's part, so I can't think its that.
I've tried searching documentation on how to create subfolders, but of the preciously few results I'm getting, almost none has C# code samples, and of those, all are of the previous version of Microsoft Graph.
I'm really stumped here, I'm amazed at how hard it is to find any documentation to do something that is supposed to be simple and straight forward.

Ok, so it turned out that I was blind again. Here is the correct code for what I was trying to do:
private void SetupMailBoxes()
{
SmartLog.EnterMethod("SetupMailBoxes()");
MailFolder inbox = null;
try
{
bool dbErrorFolder = false;
bool exchangeErrorFolder = false;
inbox = _journalMailbox.MailFolders.Inbox.Request().GetAsync().GetAwaiter().GetResult();
if (inbox.ChildFolderCount > 0)
{
inbox.ChildFolders = _journalMailbox.MailFolders.Inbox.ChildFolders.Request().GetAsync().GetAwaiter().GetResult();
}
if (inbox.ChildFolders != null)
{
for (int i = 0; i < inbox.ChildFolders.Count && (!dbErrorFolder || !exchangeErrorFolder); i++)
{
if (inbox.ChildFolders[i].DisplayName.ToLower() == "db-error-items")
{
dbErrorFolder = true;
}
else if (inbox.ChildFolders[i].DisplayName.ToLower() == "exchange-error-items")
{
exchangeErrorFolder = true;
}
}
}
else
{
inbox.ChildFolders = new MailFolderChildFoldersCollectionPage();
}
if (!dbErrorFolder)
{
try
{
var folder = new MailFolder()
{
DisplayName = "DB-Error-Items",
IsHidden = false,
ParentFolderId = inbox.Id
};
folder = _journalMailbox.MailFolders[inbox.Id].ChildFolders.Request().AddAsync(folder).GetAwaiter().GetResult();
inbox.ChildFolders.Add(folder);
}
catch (Exception ex)
{
throw;
}
}
}
catch (Exception exp)
{
SmartLog.LeaveMethod("SetupMailBoxes()");
throw;
}
finally
{
}
SmartLog.LeaveMethod("SetupMailBoxes()");
}

Cannot invoke method or retrieve property from null object. Object returned by the following call stack is null

I'm using CSOM and azure functions to create site collection.My workflow is first using GetAzureADAppOnlyAuthenticatedContext to get admin clientcontext,after site being created.Get the site collections clientcontext and then set site property such as add user to group,site owner etc.
It works well when debug local,but sometimes got error below:
Cannot invoke method or retrieve property from null object. Object returned by the following call stack is null. \"AssociatedOwnerGroup\r\nRootWeb\r\nSite\r\nMicrosoft.SharePoint.SPContext.Current\r\n\""
and my code like this:

It seems that sometimes the clientconetxt goes null in azure funtion

Thread abort in Window Service in C#

I have a window Service which converts the PDF file to html and it is running in 5 threads.
Each thread picks the record from database where status is 0.Once it picks the record from database we are making the status to 64 and making an entry in log file so that other thread should not pick the same record,after successful conversion we are making the status to 256 if any exception we are making the stratus to 128.
Some records are updated to 64 with out any entry in log and they are not even processed further.
Below is the Stored Procedure to pick the single record from database.
Create PROCEDURE [SGZ].[p_GetNextRequestForProcessing]
#InstanceId int
AS
BEGIN
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
set nocount on
Declare #RequestID bigint = null;
SET #RequestID= (
Select
TOP(1) RequestID
From
sgz.PDFTransformationQueue
Where
RequestStatusID=0
);
If (#RequestID is not null)
BEGIN
Begin Transaction;
Update
sgz.PDFTransformationQueue
SET
RequestStatusid=64,
ProcessedInstanceID =#InstanceId,
ProcessStartTime = getutcdate(),
ModifiedDate=getutcdate()
Where
RequestID=#RequestID and
RequestStatusid =0 and
ProcessedInstanceID is null;
if ##rowcount = 0
set #RequestID=null;
Commit Transaction;
END
Select
RQ.VersionNumber,RQ.RequestID, RP.Payload
From
SGZ.RequestPayload RP WITH (NOLOCK),
SGZ.PDFTransformationQueue RQ WITH (NOLOCK)
Where
RP.RequestId=RQ.RequestID AND
ProcessedInstanceID=#InstanceId AND
RequestStatusid =64 AND
RQ.RequestId = #RequestID;
END
And below is the window service code:-
protected override void OnStart(string[] args)
{
PDFTransAutoProcessManager pdfTransAutoProcessManager = new
PDFTransAutoProcessManager();
pdfTransAutoProcessManager.OnProcessStart();
}
And PDFTransAutoProcessManager class:-
private int _runningAsyncThread = 0;
private int _totalAsynThread = 5;
public void OnProcessStart()
{
_logMgr.Info("Process started # " + DateTime.Now);
mainThread = new Thread(new ThreadStart(StartAutoProcess));
mainThread.Priority = ThreadPriority.Highest;
mainThread.Start();
}
private void StartAutoProcess()
{
try
{
while (true)
{
if (_runningAsyncThread < _totalAsynThread)
{
Thread childThread = new Thread(() => ProcessAsync());
Interlocked.Increment(ref _runningAsyncThread);
childThread.Start();
}
Thread.Sleep(100);
}
}
catch (Exception ex)
{ }
}
private void ProcessAsync()
{
try
{
PDFGenieManager pdfGenieManager = new
PDFGenieManager(_logMgr,gmi);
pdfGenieManager.ProcessRawData();
}
catch (Exception ex)
{
_logMgr.Info(ex.Message);
_logMgr.Info(ex.StackTrace);
}
finally
{
Interlocked.Decrement(ref _runningAsyncThread);
}
}
And in PDFGenieManager Class actual database call and conversion will happen.
When it is trying to get records from database some records are updated to 64 with out any entry in log.
Is it related to threading pattern or any problem with stored procedure.
Kindly help thanks in advance.

In this we are taking a parameter as "Action uiRefresh" . we are calling this uiRefresh as method in GetFilesWhichNeedsToBeArchived which was in startArchiveProject method. This Refresh method in tunrn calls the method in code behind file. This was passed as a control when we are invoking startArchiveProject in code behind file. Now I have one more thing which I need to implement. I have a method Pop-Up files in code behind file. I need to call that in ProjectManager.cs class inside the Method GetFilesWhichNeedsTobeArchive. In that pop-up I will have a button and checkboxes. Upon the selection user I need to get the details from pop-up and then I have to continue with the remaining execution in ProjectManger.cs page.
Can someone help on this?

Assuming that you have a button named btnArchive then the add click event subscription, pointing to the method you have (which looks like click-event handle proc)
btnArchive.Click+=(s,e)=>btnArchive_Click(s,e);

EventStore duplicate commit exception

UPDATE:
We are getting getting System.Data.SqlClient.SqlException. The message is:
Violation of PRIMARY KEY constraint 'PK_Commits'. Cannot insert duplicate key in object 'dbo.Commits'.\r\nThe statement has been terminated
It seems like EventStore is using streamid and commitid as unique id.
We use event store to append events as below.
public bool TryAppend(object[] content)
{
if (content == null)
throw new ArgumentNullException("content");
try
{
using (var stream = m_storage.OpenStream(m_streamID, 0, int.MaxValue))
{
var versionInStore = stream.StreamRevision;
content.ToList().ForEach(m =>
{
var version = ++versionInStore;
var key = string.Format("{0}-{1:00000000}", m.GetType().Name, version);
var savedMessage = new SavedRecord(key, version, m);
stream.Add(new EventMessage { Body = savedMessage });
});
stream.CommitChanges(Guid.NewGuid());
}
return true;
}
catch (Exception e)
{
m_logger.LogError(e);
return false;
}
}
The configuration of EventStore is as below. We are using Sql Serer 2008 as persistance store.
return Wireup.Init()
.LogToOutputWindow()
.UsingSqlPersistence(m_connectionName)
.WithDialect(new MsSqlDialect())
.EnlistInAmbientTransaction() // two-phase commit
.InitializeStorageEngine()
.UsingJsonSerialization()
.Compress()
.UsingSynchronousDispatchScheduler()
.DispatchTo(new DelegateMessageDispatcher(DispatchCommit))
.Build();
Any ideas why are gettin the dupplicate commit exception?
Thanks

Have got the same issue; in my case it was probably because of different threads was adding different events to the stream with same id at the same time.
Have writtent the following code to be able to retry adding events:
private void TryAddEvent(IStoreEvents storeEvents, IUserEvent anEvent, Guid streamId)
{
var isCommitSuccessful = false;
for (var i = 0; i < 10 && !isCommitSuccessful; i++)
{
try
{
using (var stream = storeEvents.OpenStream(streamId, 0, int.MaxValue))
{
stream.Add(new EventMessage {Body = anEvent});
if (stream.UncommittedEvents.All(e => e.Body != anEvent))
{
stream.Add(new EventMessage {Body = anEvent});
}
stream.CommitChanges(Guid.NewGuid());
}
isCommitSuccessful = true;
}
catch (Exception ex)
{
if (!(ex is SqlException) && !(ex is ConcurrencyException))
{
throw;
}
using (var stream = storeEvents.OpenStream(streamId, 0, int.MaxValue))
{
if (stream.CommittedEvents.Any(e => e.Body == anEvent))
{
isCommitSuccessful = true;
}
}
}
}
if (!isCommitSuccessful)
{
throw new ConcurrencyException(String.Format("Cannot add {0} to event store", anEvent.GetType()));
}
}
Hope it would help.
