I have a task to do. I need to get the value from the tag into c#. I need to display the value into Label. This here is my HTML code:
<pre><div size="10" id="para1"></div> <p></p><asp:Label ID="Label2" runat="server" Text="" Font-Size="XX-Large"></asp:Label><p></p><asp:Label ID="Label3" runat="server" Text="" Font-Size="XX-Large"></asp:Label>
<script>
document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {
var d = new Date(),
days = ['sonday', 'monday', 'tuesday', 'Mittwoch', 'Donnerstag', 'Freitag', 'Samstag'];
return days[d.getDay()];
}</script>
from code behind i use this here to get the value but it does not work:
HtmlDocument page = new HtmlWeb().Load(@"D:\Downloads\wichtig\try\WebApplication1-Kopie-Kopie\MeineWebseite\löschen\WebForm2.aspx");
var title = page.DocumentNode.SelectSingleNode("//div[@id='para1']");
Label3.Text = title.ToString();
I only know how to get the tag by Id. This is how it works
document2.Load(@"D:\Downloads\wichtig\try\WebApplication1-Kopie-Kopie\MeineWebseite\löschen\WebForm2.aspx");
string tag = document2.GetElementbyId("para1").Name;
Label2.Text = tag;
That is how it works but I want Label3 should display the current date like
<div>id="para1</div>
The result is this here https://i.stack.imgur.com/wes2a.png

This question doesn't make a lot of sense.
You're opening an .aspx page directly from disk. This will return the raw ASP.NET file, not the generated HTML markup.
You're then trying to read the value of an element which is set by Javascript. But the HtmlAgilityPack won't execute the Javascript, so the element won't be initialized.
If you just want the German name of the current day in your label, you can do that directly:
var culture = System.Globalization.CultureInfo.GetCultureInfo("de-DE");
Label2.Text = DateTime.Today.ToString("dddd", culture); If you want to use the current culture, it's even easier:
Label2.Text = DateTime.Today.ToString("dddd");

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
So tell us what code you might have used, what you typed, what the manual says the display expects. What the manufacturer says should happen - you did check the website, didn't you?
We can't help you based on "I've got a box and it doesn't work" - which is pretty much all you have told us so far!

"LED8 customer display" means absolutely nothing to anyone but you.
We have no idea what this device is, how it communicates (there is not standard for this!), what the protocol is, what commands it accepts, ... NOTHING.
...and you want help with the very thing you didn't describe to us.
By the way, typing those commands into a CMD Prompt on Windows today does absolutely nothing.

So I have a form with windows media player,and a couple of other stuff on it.
What I want to be able to do is the following.
Using my phone, I would like to be able to control that media player from my browser.(On a local network)
Example.
I am in a other room and I want to skip the current song. I'd go into the browser open a page. Click on skip and the player will skip to the next song in the list.
I'd love if someone could give tips like the following example.
1. Create your application.
2. Create a server.
3. Create an html page.
4. Link the stuff

1. Create your application.
2. Create a server.
3. Create an html page.
4. Link the stuff What more do you need to know?
You need the app you write to set up something to "Listen" for instructions, or to connect to the web app to get it's instructions from there.
You need the web app (running locally on the LAN) to talk to the app.
3) You need to do this, and also write code-behind code to talk to the player app.
One way to do it is using a Socket - have a look at the Sockets stuff in here: Double Clicking a File in Explorer and Adding It to Your App while it's Running[^] and also here: Socket Class (System.Net.Sockets) | Microsoft Docs[^] for one way to do it. You set up a listener on the player app, and then open a connection on the webserver app to send the commands.

Sadly, you are likely right.

So your Windows Forms app is going to have to implement some kind of server so it can listen for commands.
You're going to need a web server running on the same network and a web application to take input from the user and generate commands for your Windows Forms app to process.
From your questions, you have a LOT of learning to do.
You apparently have no idea what HTML is or how to write it,
no idea what javascript is or how to write anything in it,
no idea how to build a web server, configure it,
no idea how to write a web application of any kind,
no idea how to write any kind of server application,
...
There is no way anyone is going to write several books worth of information into a few posts on this, or any other Q&A site.

Please help me, how can I to open a save file using button. my file save to the path below. Thank you
C:\SAP Scripts\Display Material Serial Number.SAP
|
|
|
|
|
To open a file with the associated application, pass the path to Process.Start:
Process.Start Method (System.Diagnostics) | Microsoft Docs[^]
Process.Start(@"C:\SAP Scripts\Display Material Serial Number.SAP"); This is the same as double-clicking the file in Windows Explorer.
If the file isn't associated with the application, then you'll need to pass the path of the application to Process.Start, and provide suitable command-line arguments to tell it to open the file.

I'm guessing he's associated with "PDF converter man" who has resurfaced at the same time. A total coincidence, I'm sure ...

Compilers can do some kinds of optimizations, and even the first fortran compiler included that capability. Function calls mean a little performance hit, so inlining of functions is a possible optimization. The C# compiler can do that, and in case it misses such a possibility, you may use the AggressiveInlining attribute.
I'd like to know when the first compiler with function inlining capability was introduced, and how common it is nowadays beyond the .Net world.
Oh sanctissimi Wilhelmus, Theodorus, et Fredericus!

Pretty sure inlining is wide-spread, it has been around for decades before .net.

It was certainly in C++ in the early nineties - there are books from that period which describe it: The Advanced C++ Book, Skinner, M. T. (1992). Silicon Press. ISBN 978-0-929306-10-0.[^]
And I recall an inline keyword in my C compiler from the eighties, though it wasn;t added to the C spec until C99. I know that many compilers do inlining without being prompted (Java for example) but ... it depends on the module type and the function visibility to an extent. If the function is visible outside the module, it's harder to inline as it can't be called from an external app unless it exists as a "proper" function / method.

By 1984 I was using a "globally optimising" Fortran Compiler at Perkin-Elmer (nee Interdata, later Concurrent). One of its tricks was function inlining fairly early in the compilation process, so redundant code could be stripped and register allocation done smarter.
It was fairly novel for its time and in its application space ("superminis"), but I'm pretty sure it wasn't the first.
Cheers,
Peter
