All printers generally available are pixel based. Thus there is no absolute way to produce a 'line'. There might be expensive line based printers. There used to be but that was when pixel based printing was very rough or even non-existent.
What one does these days is to craft a pixel based output that looks like a line. Which should be fairly easy to do now given how small the pixels are these days.
There are articles about how to do line approximation using pixels which you can google for.

You need somebody?
Ignoring The Beatles, what help do you need?
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.
The better your question, the better the answer - and the converse is also true. If you try to type as little as possible, then we get almost nothing to work from, and really can't help you at all!
Think about it as a car: you break down in the middle of nowhere, and call your local garage. The answer, you say "Help!" and put the phone down. How long do you think it will be before they work out who you are, where you are, what your car is, what happened to it, what parts they need to fix it, and drive out to get you going again?
That's what you have done here!

First off, Base64 is not encryption, it's translation. It doesn't provide any significant security at all, and can be translated back by anyone who can read the Base64 string.
It's a way to transfer binary data (which is eight bits wide) over a text based communications medium such as an email or HTML page. Text based data can accept a much, much smaller range of data characters - normally A-Z, a-z, 0-9, plus a small handful of special punctuation characters, many of which have special meanings in HTML or other transport documents.
So Base64 uses just 64 of those characters: A-Z, a-z, 0-9, + and /.
The reason for the decision to use just 64 characters is simple: it fits in exactly 6 bits, so it';s easy to pack 8 bits data into.
You do it by taking the least significant 6 bits of the first byte, and mapping it to the Base64 character set. You then take the other two bits, shift them 6 places right so they are in the bottom two bits, than add the least significant four bits of the second byte (by shifting them two places to the left). Translate that via the map, then shift the other four bits of byte 2 right four places to they are in the least significant bits, and add the least significant two bits of byte 3 (shifting them 4 places left), translate via the map. Finally, take the remaining 6 bits of Bytes 3, shift them right two places and map them.
You now have 4 bytes from three, which are in Base64. Repeat the process until you run out of input bytes!

Hey guys. I created a multiple client/server application using sockets in c#. Everything works just fine. Now can you please help me create a code that will allow a client to check if another client is connected to the server(By IP)? I have an idea but I don't know how to implement it. I want something like that:
Client #1 has connected.
Client #2 has connected.
Client #1 sends to server: "check 45.56.128.20"
if client #2 is connected, do nothing. Else:
Server sends to Client #1: "The client is not connected".
My server size code:
http://pastebin.com/vmwJFxFt
My client side code:
http://pastebin.com/YD28bNCg
(I did not write the server&client codes)
Thank you!

You need to look at the code and work out how it works: we are not here to wade though two complete apps and fix them to do what you wanted.
So far, your total effort on this is a quick google, download, compile, and then try to get someone else to do the hard bits. That's not development: you need to understand code, not just grab it and call it yours. If you don't understand code you download, how do you know that it doesn't do things you really don't want, like introduce ransomware to your computer, or worse your clients?

You are wrong. The codes I showed you are just to show the socket type I use, I improved them and added 200 lines of code but I don't want people to see the source code. I am a software deveploment student and I don't want other people to do the job for me. I just aaked a simple question because I searched all over the internet and couldn't find a solution. If you don't want to help din't help but at least don't say things you don't know.

So you want us to modify code you don't show us, don't mention in your original post, and then get shirty because we assume you haven't done anything ...

I am not asking you to modify anything bro, I just asked for help. I have a list named _clientSockets in server and all I am looking for is a way to get the IP Addresses from that list as it is a Socket, and compare it to a specific ip address so I can send a message to the IP. I really don't want you guys to do it for me. I am just tired searching, ive been trying for a week.

When a client connects, add the complete address (socket & port) to a list. When a client disconnects, remove them from said list. When a client requests whether someone is connected, look in the list and return the answer.

Doesn't matter; if you want to change the code, than I will expect you to understand each and every instruction in there.

I understand every line but I used another code I took from google that uses the same type of socket in order to give you an indication to help me. Didn't know it is not ok.
But alright, thanks

It is; but you do agree that you'll have to understand the code you are going to modify
There's also an async client/server socket example somewhere on MSDN. Ehr.. here[^]. They all have some things in common; there's some startup code (modify to create a list), there's some connection code (modify to add socket-address to list).
If you're unsure if a connection is still alive, then send some data to it; it will raise an exception if it can't be sent or received.
Alternatively, you could search CodeProject for articles like "socket chat" applications; should be a few there

Depending on the user input I create a certain number of textboxes using a loop. For example if user inputs "10" then 10 textboxes are created. TxTBox1, TxTBox2 etc etc.
How then do I create identical event handlers for these textboxes for example to validate input for them. They will all be exactly the same.

Try:
void AllTheseTextBoxes_TextChanged(object sender, EventArgs e)
{
TextBox tb = sender as TextBox;
if (tb != null)
{
string input = tb.Text;
...
}
}
private void MyButton_Click(object sender, EventArgs ew)
{
for (int i = 0; i < 10; i++)
{
TextBox tb = new TextBox();
tb.Text = "Textbox " + i;
tb.TextChanged += AllTheseTextBoxes_TextChanged;
...
}

OriginalGriff has shown you how to make all run-time created Controls use the same EventHandler. Let me add:
1. when you create a set of Controls at run-time: you probably should keep track of them ... keep a reference to the instances for future use: I got tired of writing Control specific code for this, and created a generic method:
public Dictionary<string, T> CreateControls<T>(Control container, int ncontrols, Func<T, int, string> nameGenerator, Func<T, int, Point> locGenerator)
where T : Control
{
Dictionary<string, T> dict = new Dictionary<string, T>();
string name;
for (int i = 0; i < ncontrols; i++)
{
T newT = Activator.CreateInstance<T>();
container.Controls.Add(newT);
name = nameGenerator(newT, i);
newT.Name = name;
dict.Add(name, newT);
if (locGenerator != null)
{
newT.Location = locGenerator(newT, i);
}
}
return dict;
}Sample usage:
int hstart, vstart, hoff, voff;
hstart = 100;
vstart = 100;
hoff = 0;
voff = 60;
var tbxDict = CreateControls<TextBox>(this, 5, (tbx, i) => $"newTbx_{i}", (tbx, i) => new Point(hstart + (i * hoff), vstart + (i * voff)));
var check = tbxDict["newTbx_0"].Name;When this is executed, five new TextBoxes are added to the Form this code runs in, a Dictionary is created and returned for easy future access to the created TextBoxes, and the new TextBoxes are placed on the Form in a column starting at 100,100. offset from each other vertically by 60 points.
The two functions (Delegates) that create the name and position of each new TextBox are passed as parameters to the 'CreateControls method.
Now, validation: that's the next chapter

VB6 is long dead, but it had one function I really found useful.
It was called ProperCase(), or something similar.
What it did was apply upper casing to the first letter of each word and make the rest of the word lower case. It was great for names.
Does C# have anything that performs that function?
The difficult we do right away...
...the impossible takes slightly longer.
