Hi, I am a hobbyist rather than a professional programmer so please go easy on me. I am asking about the feasibility of what I would like to achieve rather than how to actually go about programming it. (although any help gratefully received) - I have posted this in C# because it is the language I have some knowledge of, let me know if I need to move it.
The Problem
The company I work for has some software that allows us to 'publish' emails and their attachments from Outlook (2016) into a document management system. Some of the emails we receive have PDF attachments with no searchable text - just an image. We need to be able to OCR all of our PDF files as they arrive into a users Inbox. We need to keep the attachments in place so we can still publish directly from Outlook, preferably adding a [OCR] tag on the end of the filename. We need to keep the sender and recipient information as well - some OCR solutions allow you to email a server and it replies with the OCR'd documents, but it changes the senders address.
I have found a few companies who supply OCR software which comes with an SDK (Nuance and Abbyy), so I know at least that I can send a document for OCR. It is the attachment handling within Outlook I need information on. I need the workflow to look like this:
Email arrives > check for PDF attachment > If pdf found, send for OCR > save OCR result, either overwriting the original attachment or adding it to the original email but with the tagged filename.
Could anybody tell me if this level of attachment manipulation is possible with a received email?
I hope I explained my issue OK.

Yup.
How you get your image isn't important; it is a collection of bytes, and they can be sent by mail or come from another source. You can throw any kind of image into OCR-software and fetch results.
Sounds reasonable enough  Are you expecting difficulties in a particular area?

It was manipulating the attachments while they are sitting in the Outlook Inbox I was most unsure of, because it would mean replacing the original attachment.
I have seen lots of code snippets where attachments are extracted and saved, or documents attached to an outgoing email, but none that re-attach documents to the original received email. Do you think this is possible within the Outlook API then? This could solve a real headache for me. If you think the ability to do it is there, I will have to get learning the Outlook API. 
I was quite surprised that there is not already a product to do this, but I have not been able to find anything.

No, it doesn't; you should not modify the original, as it would imply to the user that the "sent" thing was changed when it is not.

Which you would do, since no OCR-library is going to read emails; that's not the responsibility of an OCR-library.
Jim607 wrote: Do you think this is possible within the Outlook API then?
I hope not; I'm pretty sure you can manipulate emails and attachments though.
Save the attachment locally, throw OCR at it, and save the results in a local DB. Don't go messing with original files.
Or, at least make a copy of the email and work on that. You want the original to debug if anything goes wrong

You keep talking about "OCR"; but I don't get the point.
There are plenty of "document management solutions" that aren't preoccupied with OCR ... which usually goes along with MICR.
A "file name" is as good as some "other tag" when thought out properly; while "document management systems", by default, allow one to apply other attributes to a document for searching.

Hmmm,
I'm not a C# guy but I do know that 0xc00000fd is not a memory leak... that's a stack overflow.
Best Wishes,

As Randor says, Exception code 0xc00000fd is a stack overflow, not a memory leak - always Google exception codes if you don't know what they mean.
And there is only really one way to cause a stack overflow in a C# app: recursive code.
So start by looking through your code to find what might be recursing slowly - and I do mean slowly, if it's taking days then it's really slow - the stack is normally only around one megabyte, so it doesn't take much for a wildly recursing app to overflow it.
We can't do that for you, and the timescale involved makes the debugger less than practical so you are going to have to fall back on the old ways and add logging code to your app to find out where it enters a method, and doesn't exit before the method is called again. Hopefully, your app is written in a well structured way and that won't be too complicated.

Thanks,
I am using Response.Redirect("~/Error.aspx");
So, Thread is aborted, this can be also cause to pressure in Stack?
Shall we use Response.Redirect("~/Error.aspx", false); ?
Thanks

We cannot tell.
We have no idea what your code is doing, because we can't see it!
You need to start logging this: at the moment you have no information, and are just guessing what is causing this.

Hello,,
I need to find the first and second most repeated element in an array.If there are two most repeated numbers then it needs to print the maximum among them.can anyone suggest a solution for it.

Look at some of the answers below to your original question. You just need to adjust the code for the different counts that you want to collect.

What have you tried?
We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
We can't just "give you a solution" even if we wanted to, because we have no idea how far you are into your course: the solution I'd use - a Linq Query - wouldn't work for you if Generics and Linq are still to be covered in your course.
And of course there is this: your tutor knows this site exists. He will be looking for students handing in other people's work as their own - it's called plagiarism - and can throw you off the course, or out of the school...
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

this is the code which i tried.it is actually giving output for first frequent element but producing a false output for second frequent.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp14
{
class Program
{
static void Main(string[] args)
{
int i, j, count, maxcount = 0, number = 0, n = 10, part1 = 0, part2 = 0, number1 = 0;
int[] array = new int[10];
for(int k=0;k<10;k++)
{
array[k]= Convert.ToInt32(Console.ReadLine());
}
for (i = 0; i < n; i++)
{
count = 0;
for (j = 0; j < n; j++)
{
if (array[i] == array[j])
count++;
}
if (count > maxcount)
{
maxcount = count;
number = array[i];
}
else
if (count == maxcount)
{
if (array[i] > number)
number = array[i];
}
}
maxcount = 0;
for (i = 0; i < n; i++)
{
count = 0;
if(array[i]==number)
{
continue;
}
for (j = 0; j < n; j++)
{
if (array[i] == array[j])
count++;
}
if (count > maxcount)
{
maxcount = count;
number1 = array[i];
}
else
if (count == maxcount)
{
if (array[i] > number)
number1 = array[i];
}
}
part1 = number;
part2 = number1;
Console.WriteLine(part1);
Console.WriteLine(part2);
Console.ReadKey();
}
}
}

And now it's time for you to learn to use the debugger!
Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.
Time for you to learn a new (and very, very useful) skill: debugging! Trust me, get used to this - you will be using this a lot, and it's well worth learning while you are dealing with nice, little, self contained problems like this one - trying to learn it on a million line of code behemoth is a lot worse!
Give it a try: You'll be surprised now much information you can get.

Assuming they are teaching using VS I'm astonished that debugging is not the second lesson taught - hello world being the first. Surely a basic knowledge of the IDE would be primary. Or maybe they expect the students to explore the IDE, just like we all did.

And perhaps teaching that a clean compilation does not mean your code is right...

I'm not; followed several courses and there's usually no explanation of the IDE, or debugging techniques.

In every class I ever took, basic debugging and debugging techniques were never covered. From what we're seeing in the forums and QA, I'd say that's still the case.
Thankfully, I already knew what I was doing when I walked into those classes.

Why learn that when you can use Code Project?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

Debugging is for wimps. Just get it right the first time. I don't even build anything any more, just check it into source control and whack the publish button.

Rob Philpott.

Dear All,
I add a dolder in solution explorer tree. And I add txt files into it.
How can I read it from there?
Thanks.
