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()");
}

How to Gstreamer's udpsrc display (wpf)

On the command line it works fine.

how to use application/x-rtp binding with gstreamer-sharp?
I've changed the caps location to udpsrc,
I have tried autovideosink, etc.

Gst.Video.Global.IsVideoOverlayPrepareWindowHandleMessage(msg)
will be not null only if you have autovideosink in your pipeline. This is because a Window creation request will be created if you have Window "VideoSink" like autovideosink, glvideosink... which implements GstVideoOverlay. (https://gstreamer.freedesktop.org/documentation/opengl/glimagesink.html?gi-language=c#hierarchy see implemented interfaces)
pipeline.Add(udpsrc, jitter, depay, avdec, convert, ink);
Why not setting your pipeline to playing instead of ready ?
var ret = pipeline.SetState(State.Playing);

Validating digitaly signed PDF Spire.Pdf C#

So I am developing a web app that generates a PDF contract from a partial view, and then validates the digital signiture. I came accross an example here . The problem is that an exception is thrown when validating the signiture and for the life of me I cant figure out why...
Here is the code :
public async Task<ActionResult> Upload(HttpPostedFileBase FileUpload)
{
ActionResult retVal = View();
AspNetUser user = DbCtx.AspNetUsers.Find(User.Identity.GetUserId());
bool signitureIsValid = false;
string blobUrl = string.Empty;
if (FileUpload != null && FileUpload.ContentLength > 0)
{
string fileName = Guid.NewGuid().ToString() + RemoveAllSpaces(FileUpload.FileName);
string filePath = Path.Combine(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/pdfs"), fileName);
FileUpload.SaveAs(filePath);
List<PdfSignature> signatures = new List<PdfSignature>();
using (var doc = new PdfDocument(filePath))
{
var form = (PdfFormWidget) doc.Form;
int count = 0;
try
{
count = form.FieldsWidget.Count;
}
catch
{
count = 0;
}
for (int i = 0; i < count; ++i)
{
var field = form.FieldsWidget[i] as PdfSignatureFieldWidget;
if (field != null && field.Signature != null)
{
PdfSignature signature = field.Signature;
signatures.Add(signature);
}
}
}
PdfSignature signatureOne = signatures[0];
try
{
signitureIsValid = signatureOne.VerifySignature(); // HERE SHE BLOWS !
if (signitureIsValid)
{
blobPactUrl = await BlobUtil.BasicStorageBlockBlobOperationsAsync(System.IO.File.ReadAllBytes(filePath));
if (!string.IsNullOrEmpty(blobPactUrl))
{
ApplicantInfo info = DbCtx.ApplicantInfoes.FirstOrDefault(x => x.UserId == user.Id);
info.URL = blobUrl;
info.SignatureIsValid = true;
info.ActivationDate = DateTime.Now;
info.ActiveUntill = DateTime.Now.AddYears(1);
DbCtx.Entry(info).State = System.Data.Entity.EntityState.Modified;
DbCtx.SaveChanges();
retVal = RedirectToAction("Publications");
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
System.IO.File.Delete(filePath);
}
}
return retVal;
}
Here is an image of
what it looks like when I'm debuging:
I have checked the signiture and it is valid and cerified... I know I'm missing something basic here... Please help me internet!

Just noticed that I posted this. . . Turns out that the problem was due to bug in the package itself. Upon asking the lovely people at E-Iceblue, the bug was recreated, solved and a new version of Spire.PDF was up on nuget within a week.
great job E-Iceblue, it worked fine :)

Using ManagementObjectSearcher and Win32_Printer to check Status

I have been forced to use the RawPrinterHelper class to print to a thermal printer because the PrintDocument method has proven unfit for POS printing.
I now need to check the status of the printer prior to printing to be sure that it is, online and ready to print. I have been able to successful check attributes from Win32_Printer. I can see properties such as PrinterStatus, changing from 3, to a 2 or a 1 when out of paper or tray is open. This is great.
My question is, which properties should indicate it is O.K. to print? There must be more than just checking if PrinterStatus is idle (3).
private bool ReadyCheck(string printerName)
{
bool ready = false;
string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName);
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
using (ManagementObjectCollection coll = searcher.Get())
{
try
{
foreach (ManagementObject printer in coll)
{
// Print status = 3, idle and ready to print
string status = printer.Properties["PrinterStatus"].Value.ToString();
string extendedPrinterStatus = printer.Properties["ExtendedPrinterStatus"].Value.ToString();
// What else means printer is ready?
if (status.Trim() == "3")
ready = true;
}
}
catch (ManagementException ex)
{
Console.WriteLine(ex.Message);
}
}
return ready;
}
Edit:
#vendettamit Sorry I didn't ask very well. For instance, Idle (3) indicates it's OK to print. I am wondering if there are more which also indicate it's OK to print such as; Printing (4), WarmUp (5), ect, or is Idle (3) the only time you should send the next print job? Thanks

Below are the values that you can take into account to check if It's ready to print:
Other (1)
Unknown (2)
Idle (3)
Printing (4)
Warmup (5)
Stopped Printing (6)
Offline (7)
Also a note from Remarks on MSDN documentation for Win32_Printer-
If you are retrieving PrinterStatus = 3 or PrinterState = 0, the printer driver may not be feeding accurate information into WMI. WMI retrieves the printer information from the spoolsv.exe process. It is possible the printer driver does not report its status to the spooler. In this case, Win32_Printer reports the printer as Idle.

Everything goes fine there are no exceptions still the data isn't getting updated. I don't know what's the issue. Please help?

The line:
objCategoryNew = objCategory;
will not work out since you change the reference objCategoryNew to objCategory, not the object itself, what you have to do is to assign each property of objCategory to objCategoryNew, something like:
objCategoryNew.Pro1 = objCategory.Pro1;
objCategoryNew.Pro2 = objCategory.Pro2;
....
