I'm sure that made a lot of sense to you because you have everything in front of you, but to those of us on the other side of the chat window are doing this completely blind and have only what you type in a textbox to work with.

What you said made no sense whatsoever.

Why on earth would you specify the same email address twice in two different fields? I just don't see the reason for it.

You're not disagreeing with me. You're disagreeing with the server. You have to follow its rules, not mine.

4.8 doesn't have many options, so the only thing I can think of that's stopping it from running is the Platform type. You say it's set to Any CPU, but try it explicitly set to x64 or x86 if you've got external .DLL dependencies.

Dave Kreskowiak 29-Apr-24 12:21pm View

This is why security systems use information from all over the system, not just a single serial number on a device.

I would suggest finding a commercially available protection system and not roll-your-own.

What do you think you were going to do with the serial number? Store it somewhere the customer could easily find? How was the app going to check to see if the "license" is still valid?

It's FAR more possible that you will find the authors of the work, I don't know, maybe on the site where they posted the work!

Dave Kreskowiak 29-Apr-24 9:48am View

Let's clarify a bit. NO hardware is required to have serial numbers on it.

MAC addresses are NOT globally unique. The first three bytes of the MAC are the vendor identifier, which are used to id the vendor that made the adapter and maybe a product line. The last 3 bytes are the "serial number", but since that's only 3 bytes (a range of 16.7 million values,) it is entirely possible to have multiple adapters with the same MAC. You just can't have more than one copy of a MAC address on a network segment.

Oh, and nobody needs to "hack" a MAC address. There are network cards out there, or more specifically, their drivers, that will let you change the MAC address to whatever you need to avoid collisions with other cards.

Dave Kreskowiak 29-Apr-24 9:35am View

No. Serial numbers are not required to be present by any standard.

Dave Kreskowiak 28-Apr-24 13:38pm View

The 500 error means either you're sending data to the controller in the wrong format, in the wrong place in the request so that it couldn't be parsed on the server side, or your server side code crashed for some reason.

Looking at the bottom of what you posted, it seems you should be sending a value for "idunidad", but either that value doesn't exist, or isn't being handled correctly in your controller method: "ListarIntegrantesUnidad", "Mantenedor".

While it's possible to start the executable and not wait for execution to complete, the executable will STILL sit there waiting for a keypress that will never show up.

Also, the OP never mentions it, but it is entirely possible the executables must be run synchronously and do not support being run at the same time.

So, yes, I do know what is possible and what isn't. In this case, there isn't sufficient information to make a call either way.

First, I would NEVER just edit a csproj file to change from a .NET Framework project to a .NET core project. I'd make an entirely new project and copy whatever source files I need over to the new project.

SELECT * returns every column in a table(s), even the ones you may not need. This increases the load on the SQL server and needlessly increases the amount of data coming back from the database.

Next, the columns returned may not be in the order you expect, so code that uses index numbers to identify columns is easily broken when you start adding/removing columns from tables.

You're right about .Value. It's not needed. I've been spending a lot of time doing my work in ORMs and WMI lately so I forgot the database Reader syntax. Whoops!

Sure, it works fine on your dev machine with a single user. The instant you get two users launching that code at the same time, Office will fail. Office interop does not support re-entrancy, or more than one thread using the library at the same time. The code will crash and you'll get problem reports from the users that you will not be able to replicate.

Using COM-interop is out of the question. You'll have to use a library dedicated to manipulating Excel files, like OpenXML, ClosedXML, or similar.

KISS even applies to books. Each paragraph represents a method, describing a single topic. You'll be hard pressed to find a paragraph that occupies an entire page of a book, let alone and entire chapter.

Dave Kreskowiak 14-Mar-24 22:49pm View

A method should have a SINGLE, very clear and small purpose and do that one thing only. If it has to call another method to do something else that needs to be done, that's fine. The concept is called "separation of concerns." Code should be small and modular. This organizes your code to make it more readable, debuggable, and easier to maintain.

As for the how, that would take entire books to explain.

Dave Kreskowiak 14-Mar-24 12:52pm View

If you've got blocks of code that are THAT long, you've got serious organization issues. Try to keep methods down to about 20 to 30 lines of code max.

You would be much better off asking your customer what else is running on this production SQL server. The server is taking up the memory it needs to support whatever else it's doing, possibly outside of the work of your application.

One of the production SQL Servers I run works on 8GB of RAM for months at a time and it only takes about 3 to 4GB of RAM the entire time it's running, for a database that's about 14GB.

There's more running on your customers server than you know about.

...which GROW and shrink their usage AS REQUIRED

SQL Server is written to take up as much memory as it can get away with for performance reasons, mostly for caching indexes and other data.

You're reading it like it should play nice with everything else running on the server. It doesn't play nice. It favors its own performance over that of other non-SQL related processes.

I don't think anyone is going to have any idea, short of the people who own the service you're trying to get data from.

It doesn't matter how you frame the question. You will still have the exact same problem. Memory pressure detection works, just not how you think it does.

Your overall problem is still the same. YOU ARE RISKING PRODUCTION by putting UNSTABLE AND UNSECURED non-production work on the same server as production work. In every environment I've worked in the last 30 years this would never be allowed.

Dave Kreskowiak 22-Feb-24 10:11am View

Oh, it's the correct answer all right.

What you're not considering is if you screw something up on the test instance and it start hogging all the memory on the box, you're going to bring production to a halt.

There is no "option" for this in any library. This comes down to a fundamental misunderstanding of how forms, which are really just classes, work. There is no such thing as "transferring data through forms to other forms".

If you're going to use a third-party server, like Exchange, you are bound by their terms of service. If they say you cannot use the server for mass emails, you can't use their servers. It's that simple.

One way around this would be to build your own email server, then you can abuse the crap out of it all you want. The downside to that is you have to be knowledgeable about the care and feeding of the server itself and the configuration and maintenance of the email server running on it.

You're getting Bad Request because what you're sending in your request, or NOT sending, isn't valid as far as the server is concerned.

For example, you could be missing a header the server is expecting, or sending a header value that isn't valid. You could be requesting a POST on a method that doesn't accept POST, you could be passing a return content type the server doesn't support, ...

As a side, if you create a HttpWebRequest object passing in a URI, you do not need to set the Host property on it.

And they are ALL absolute garbage. There is nothing stopping me from creating an email address, using it for a day, then killing it.

To you, it's still a "valid" address, but there is literally no way to contact an email server and ask if it has a valid address. That functionality USED to exist, briefly, before it was determined that is a security risk. Now, even if the server still supports it, those requests are always filtered out.

What you're looking at is a server that has records of email addresses that WERE used at one time or another, collected over time not from servers, but from other email lists used for direct mailings. It is in no way a list of current, valid email addresses.
