Exception from HRESULT: 0x80004004 (E_ABORT) at Outlook.Mailitem.getHtmlBody()

I have a custom add-in which gets the body on clicking a button when it got installed. so I am getting this error on a customer machine. code is working fine on my side and for other customers but one customer is facing this problem.
this is my code

In the event handler of your button I see the following lines of code:
Microsoft.Office.Interop.Outlook.Application olApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.NameSpace ns = olApp.GetNamespace("MAPI");
There is no need to create a new Outlook Application instance in the add-in. Instead, you need to use the Application property which doesn't trigger a security issue when dealing with OOM from external applications:
var app = Globals.ThisAddIn.Application

c# - How to call/link a workflow on a web application from a c# program?

I have a C# (WinForms) application that can scan documents via a printer. After scanning, I will be able to enter document details on it and have a button to finalize the documents. The documents details and info will be stored in my database ABC in certain tables.
Now, I have another web application written in Java(IntelliJ) that has some button functionality to upload documents and then start a workflow and route it to another user to approve the document. I won't go into detail on the specifics. This application also connects to the same database ABC.
So now comes the tougher part, I need to link these two applications in a way that when I finalize my document
on the C# application, it has to auto trigger the workflow on the web application side. Rather than manually starting the workflow on the web application, it would just call or trigger the workflow, so I do not need to access the web application at all for the process to start.

I would appreciate any suggestions or pointers on this. Do let me know if there is anything unclear in my explanation.

Is there a way I could call this from the C# application?

You can send your file directly from your C# app with use of Http client. Here is code sample:
private async Task<bool> Upload(string filePath)
{
const string actionUrl = #"http://126.32.3.178:8111/process/taskmanager/start/start.jsp";
var fileName = Path.GetFileName(filePath);
var fileBytes = File.ReadAllBytes(filePath);
var fileContent = new ByteArrayContent(fileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileContent, fileName);
var response = await client.PostAsync(actionUrl, formData);
return response.IsSuccessStatusCode;
}
}
Also, note that there maybe some sort of authentication should be performed before you can post a request.

How to ignore protected pdf's?

I am writing on my pdf-word converter and I just received a really strange exception witch makes no sens to me.
Error:PdfiumViewer.PdfException:{"Unsupported security scheme"}
Its the first time that such a exception appears. but I have to be honest that I never tried to convert more then 3-4 files from pdf to word and right now I am doing more then 100 files.
Here is my code I am sry if its too long but I simply do not know on which line the error occurs
public static void PdfToImage()
{
try
{
Application application = null;
application = new Application();
string path = #"C:\Users\chnikos\Desktop\Test\Batch1\";
foreach (string file in Directory.EnumerateFiles(path, "*.pdf"))
{
var doc = application.Documents.Add();
using (var document = PdfiumViewer.PdfDocument.Load(file))
{
int pagecount = document.PageCount;
for (int index = 0; index < pagecount; index++)
{
var image = document.Render(index, 200, 200, true);
image.Save(#"C:\Users\chnikos\Desktop\Test\Batch1\output" + index.ToString("000") + ".png", ImageFormat.Png);
application.Selection.InlineShapes.AddPicture(#"C:\Users\chnikos\Desktop\Test\Batch1\output" + index.ToString("000") + ".png");
}
string getFileName = file.Substring(file.LastIndexOf("\\"));
string getFileWithoutExtras = Regex.Replace(getFileName, #"\\", "");
string getFileWihtoutExtension = Regex.Replace(getFileWithoutExtras, #".pdf", "");
string fileName = #"C:\Users\chnikos\Desktop\Test\Batch1\" + getFileWihtoutExtension;

Outlook 2007: Reading Pane is not updated when an encrypted Email is imported

we use Redemptiontools to develop a Addin for Outlook. At first we create Emailstubs from a Metadataset. When the User select a Mail we load a msg file from the Network and import it into the Emailstub. We dont have any problems in Outlook 2010/2013/2016.
But in Outlook 2007 the reading pane doesnt refresh if the mail has a Signature. I have deselect and reselect the Mail and then i can see the new mail.
Creating the Emailstub from an metadataset:
using (ComObjectWrapper<RDOFolder> rdoFolder = RDOSession.Resource.GetFolderFromID(folderEntryID).WithComCleanup())
{
using (ComObjectWrapper<RDOMail> mailstub = rdoFolder.Resource.Items.Add().WithComCleanup())
{
mailstub.Resource.Sent = true;
mailstub.Resource.SenderName = metadatamail.SenderName + " ";
mailstub.Resource.SenderEmailAddress = metadatamail.SenderEmailAddress + " ";
mailstub.Resource.SentOnBehalfOfName = metadatamail.SentOnBehalfOfName + " ";
mailstub.Resource.SentOnBehalfOfEmailAddress = metadatamail.SentOnBehalfOfEmailAddress + " ";
mailstub.Resource.Subject = metadatamail.Subject + " ";
mailstub.Resource.ReceivedTime = metadatamail.ReceivedTime;
mailstub.Resource.Body = metadatamail.Body + " ";
mailstub.Resource.To = metadatamail.To + " ";
mailstub.Resource.ReceivedByName = metadatamail.ReceivedByName + " ";
mailstub.Resource.UnRead = metadatamail.UnRead;
if (metadatamail.ContainsAttachments)
{
var Attach = mailstub.Resource.Attachments.Add(new char[0]);
Attach.FileName = "Attachment.txt";
}
mailstub.Resource.Save();
}
}
Importing the msg file in the selection change Event of the Explorer (expl):
void expl_SelectionChange()
{
using (var selection = expl.Selection.WithComCleanup())
{
foreach (var item in selection.Resource)
{
if (item is Outlook.MailItem)
{
string entryID = (item as Outlook.MailItem).EntryID;
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
if (!string.IsNullOrEmpty(entryID))
{
using (var researchEntry = RDOSession.Resource.GetMessageFromID(entryID).WithComCleanup())
{
string mailpath = GetEmailFromNetwork(entryID);
if (!string.IsNullOrEmpty(mailpath))
{
Redemption.SafeMailItem sItem = new Redemption.SafeMailItem();
sItem.Item = researchEntry.Resource;
sItem.Import(mailpath, (int)rdoSaveAsType.olMSG);
sItem.ReleaseComObject<Redemption.SafeMailItem>();
researchEntry.Resource.Save();
}
}
}
}
}
}
}
RDOSession:
private ComObjectWrapper<RDOSession> RDOSession
{
get
{
try
{
var rdoSession = Activator.CreateInstance(Type.GetTypeFromProgID("Redemption.RDOSession")) as RDOSession;
if (rdoSession != null)
{
rdoSession.MAPIOBJECT = this.Application.Session.MAPIOBJECT;
return rdoSession.WithComCleanup();
}
}
catch { }
return null;
}
}
Does anyone have a hint or a solution?
