This question is screaming "do my homework for me".

Dave Kreskowiak 3 days ago View

Your question isn't so "simple". You never said what you want as an answer. It's so vague it could be anything from a question about a problem you never said anything about, up to someone taking hours to write up an entire tutorial, walking you through the entire development process, which is never going to happen.

So what's the real question? Just posting "I want to do this" isn't a question.

Maybe, but I'm not watching the video to find out. For the sake of my sanity, I don't want to see the "quality" of the code in person.

Why .NET 7? It was end-of-life'd back on May 14th this year.

The odd-numbered versions have a shorter lifespan than the even numbered versions. Even versions are the Long Term Support (LTS) versions.

Support for .NET 8 continues to November 10th, 2026, so it would be better if you went that route.

That PowerShell command does not "clear the clipboard". It's stopping and restarting the clipboard user service. That's a little extreme for "clearing the clipboard" because it impacts the clipboard system-wide.

If you want to "clear" the clipboard, what's wrong with just putting an empty string on it?

Well, I raise you my 46 years of writing code. Richard is correct. Your solution, though it worked for YOU AND ONLY YOU, does not work when more than one user is on the site at the same time. You ARE leaking state between sessions since static variables are shared between all instances.

You have to run this in the debugger and step through the code line-by-line. It's possible you're not passing in the date parameter correctly, giving you 0 records returned. It's possible you're getting back more than one record, but the data you're trying to show in the lblevent control is getting an empty string or null. Your code doesn't build a string of all possible customerID's returned. It's constantly replacing the content in the lblevent control until there is no more data to read.

Now, are the dates stored in the database as strings or an actual date type?

Since you're passing the date into the parameter as a string, that will not work for a date type in the database. You're passing the date you're searching for as a string, not as a proper date. But, I don't do MySQL, so I may be wrong here.

Once again, this is just more proof you don't know what you're talking about. On which drive, the .NET Framework or .NET is installed does not matter in the slightest.

The error message is quite clear if you read it. There is a COM class you're code is trying to create an instance of and that class is not installed or registered on your machine.

You also don't need the command timeout as the default is 30 seconds. If the database can't come up with a count of matching records out of 120,000,000 inside 30 seconds, you have other problems with the database, like no indexing.

Dave Kreskowiak 8-Jul-24 14:17pm View

Then this should work:

cIndicatorx = "1234567"
Using conn As New MySqlConnection(myConnectionString)
    Using comm As New MySqlCommand("SELECT COUNT(Sequenza) FROM SeqFam1_20_60 WHERE Sequenza LIKE @SeqToFind", conn)
        comm.Parameters.AddWithValue("SeqToFind", cIndicatorx & "%")
        conn.Open()
        Dim count As Integer = comm.ExecuteScalar()
        conn.Close()
        Return (count > 0)
    End Using
End Using

The advantage of the above code is this code is more debuggable by not combining multiple statements into a single statement, giving you the opportunity to see variable contents at every line of code when run under the debugger. For example, now you can see exactly how many records were found by the database, and don't need conversions, making the code simpler.

Dave Kreskowiak 8-Jul-24 14:05pm View

I suspect you don't have a reference to the appropriate library defined.

It makes me wonder what is really behind AI. Someone wrote it, or it's a bunch of students who are now just trying to troll us, given some of the answers it comes up with. :)

Dave Kreskowiak 30-May-24 9:09am View

This is a joke, right? You posted a lot of meaningless, incomplete code, and to top it off, the last block of code you posted is so simple and doesn't use any of the other code you posted, at all.

On top of that, you never described a problem you're having, nor have you said anything about what this code is supposed to do compared to what you expect it to do.

Also, I get the feeling you are not "Aa'ishah Van Witt", nor are you "Moegamat Zaihd Behardien", who posted near identical code over on StackOverflow, with the same format of what you posted here, a long, badly formatted, and meaningless post and again without any error messages.

At a minimum, this tells me you're either trying to hide from your teacher because they know about CodeProject and StackOverflow, or you're trying to write code for your homework assignment using AI and have quickly run into the fact that AI cannot write code.

Dave Kreskowiak 29-May-24 10:32am View

It's not the library. Training and running an AI model is extremely resource intensive and you're expecting a lot from a machine with limited resources. If you can use a cloud-based solution, that would free up your machine to do other things.

No. Like I said before, once an object is no longer pinned, the garbage collector is free to move the object in memory any time it wants.

Generally this isn't a good idea, but you can, limit CPU usage using either "nice" or "cpulimit". Limiting memory usage can be done with "prlimit".

Keep in mind, doing this opens up a pandora box of issues that may cause your code problems and make it more difficult to diagnose them.

That's because AddrOfPinnedObject doesn't take any arguments. When you called GCHandle.Alloc, it returns a GCHandle object, which you stored in "handle". The correct code should have been:

GCHandle handle = GCHandle.Alloc(person_1, GCHandleType.Pinned);
IntPtr address = handle.AddrOfPinnedObject();

But keep in mind, the instant you call handle.Free();, that address isn't valid anymore.

Windows does not maintain a list of which applications were opened in what order. There is no such thing as "last opened".

The best you're going to get is whatever the top window in the z-order is. Read: Window Features - Win32 apps | Microsoft Learn[^]. It covers the functions used to interrogate the z-order.

You might get away with this if you don't need less than 1 second accuracy. The BackgroundService would have to execute once a second and check a list of scheduled times to see if the current time is in the list. If it is, execute the method attached to that time.

There isn't any more explaination. You simply have a misunderstanding of how code is executed. You seem to think Visual Studio is executing your code and it's not.

Every time you hit the little green triangle in Visual Studio, it is compiling the code into an executable and running that.

Dave Kreskowiak 14-May-24 16:58pm View

You are ALWAYS creating and running an executable. Just because you run the code from inside Visual Studio does not mean VS is running the code. VS will compile the code into an executable, run it, then attach the debugger to that running instance.

Without you showing the code and full error messages, it's impossible for anyone to help you.

And if you're getting "header file errors", your code never started running because that would be a compiler error. You never got an executable, so your code never started running.

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.

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?

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.

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.
