How do I specify the location where my User Control shows?

I am extremely new to C# and any help would be appreciated. I am trying to create a simple multiple option menu with User Controls and I have got it in a semi functional state. I am trying to get the user controls to show in a certain location because as of now they are only showing from the top left down and that is not where I would like them. Any help would be appreciated. My Form1 code is below:
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Menu_V2
{
public partial class Form1 : Form
{
StartScreen u1;
Softaim u2;
Triggerbot u3;
Macro u4;
Misc u5;
public static bool flag = true;
public Form1()
{
u1 = new StartScreen();
u2 = new Softaim();
u3 = new Triggerbot();
u4 = new Macro();
u5 = new Misc();
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void toolStripContainer1_ContentPanel_Load(object sender, EventArgs e)
{
}

Application.Exit();
}

{
u1.Hide();
u2.Hide();
u3.Hide();
u4.Hide();
u5.Show();
u5.Dock = DockStyle.Fill;
this.Controls.Add(u5);
}
private void insert(object sender, KeyEventArgs e)
{
}
private void bunifuThinButton21_Click(object sender, EventArgs e)
{

How to store the values ​of the size of window, margin and textbox C# WF

It is necessary that after closing the program, it retains the size of the window, the values ​​of the CheckBox and what was entered in the TextBox.Can you write me a code?
namespace WindowsFormsApp8
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
}
private void checkBox2_CheckedChanged(object sender, EventArgs e)
{
}
}
}

How do I call the PerformClick() function in C#?

I have three different buttons but now I want to call each even at the same time using one button.
I am unable to find the button.PerformClick() option, instead I have button.PerformLayout().
This is what I have:
private void ButtonTagStart_Click(object sender, EventArgs e)
{
//Something
}
private void ButtonLoadxHTMLTags_Click(object sender, EventArgs e)
{
//Do Something
}
private void btnStrt_Click(object sender, EventArgs e)
{
//Do Something
}
I want:
private void Button2_Click(object sender, EventArgs e)
{
ButtonTagStart.PerformClick();
ButtonLoadxHTMLTags.PerformClick();
btnStrt.PerformClick();
}
What shall I do?

you can create a method for each button
private void Something1(){}
private void Something2(){}
private void Something3(){}
private void ButtonTagStart_Click(object sender, EventArgs e)
{
Something1();
}
private void ButtonLoadxHTMLTags_Click(object sender, EventArgs e)
{
Something2();
}
private void btnStrt_Click(object sender, EventArgs e)
{
Something3();
}
in the last button invoke them all:
private void Button2_Click(object sender, EventArgs e)
{
Something1();
Something2();
Something3();
}

Can't put more than one number in the textbox. in my Simple Calculator program

Need help in making a simple calculator. i can't put more than one number in my calculator's textbox. Everytime i put a second number it replaces the first one need help!
I can't exceed more than one input number in my Calculator's Textbox instead it replaces the first number with a second number input
namespace Calculator_Project
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void InputOutputArea_TextChanged(object sender, EventArgs e)
{
}
private void One_Click(object sender, EventArgs e)
{
int Input = 1;
InputOutputArea.Text = Input.ToString();
}
private void Two_Click(object sender, EventArgs e)
{
int Input = 2;
InputOutputArea.Text = Input.ToString();
}
private void Three_Click(object sender, EventArgs e)
{
}
private void Four_Click(object sender, EventArgs e)
{
}
private void Five_Click(object sender, EventArgs e)
{
}
private void Six_Click(object sender, EventArgs e)
{
}
private void Seven_Click(object sender, EventArgs e)
{
}
private void Eight_Click(object sender, EventArgs e)
{
}
private void Nine_Click(object sender, EventArgs e)
{
}
private void Eql_Click(object sender, EventArgs e)
{
}
private void AddB_Click(object sender, EventArgs e)
{
}
private void Minus_Click(object sender, EventArgs e)
{
}
private void MultiplyB_Click(object sender, EventArgs e)
{
}
private void DivideB_Click(object sender, EventArgs e)
{
}
private void Zero_Click(object sender, EventArgs e)
{
}
private void ResetB_Click(object sender, EventArgs e)
{
InputOutputArea.Clear();
}
}
}

You should use
InputOutputArea.Text += Input.ToString();
(note the '+') in order to append to a text box.

private void Two_Click(object sender, EventArgs e)
{
int Input = 2;
InputOutputArea.Text += Input.ToString();
}
You must use += to add other text to next of first text

Here is your problem:
InputOutputArea.Text = Input.ToString();
This replaces the content of the textbox instead of adding to it.
InputOutputArea.Text += Input.ToString();
the above code should do as you ask.
Good to remember is that concatenating strings with + is rather inefficient, so don't do this in performance critical code unless absolutely necessary. In those cases a String-builder is almost always better.

Every answers talking about the Concatenation of the previous text with the current, But I would like to suggest something more than that;
You need not to create separate event handlers for all your buttons that are doing same tasks, Hope that the Text of each button will be the number that you need to display in the textBox(say btnOne will holds 1 and btnTwoholds 2 and so on). By make use of this Text we can reuse the handlers like the following, Let btnNumber_Click be the handler and which is defined like the following:
private void btnNumber_Click(object sender, EventArgs e)
{
Button currentButton = sender as Button;
InputOutputArea.Text += currentButton.Text;
}

Update Tab's Name in C# Web Browser

I'm working on a Web browser in Visual Studio 2010, but I can't update the tab's name to the website's name. For example, when you visit a website like CNN.Com, I want the tab to also say, "cnn.com". The project isn't using the default WebBrowser form, by the way. Please explain it in the simplest way possible since I'm new to C#(Just moved from C++ and Java) so I'm not familiar with working with Windows forms. Thanks. Any help is appreciated.

Assuming WebBrowser is the built-in WebBrowser, you can fire the OnDocumentTitleChanged event to change the tab text every time the WebBrowser document title is changed.
to do this, in the form load event, after declaring browse, start typing browse.DocumentTitleChanged += and a tooltip should come up saying 'tab to insert this code' or something along those lines. Just tab twice and Visual Studio will insert a new method for you, with a throw new NotImplementedException(); line. Delete that line and replace it with the code changing your tab's text to the browser's DocumentTitle.
If you need any more information, I suggest you check the documentation:
http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.aspx
Though I am confident that using events is the best solution. Events are designed to execute upon certain significant programming 'events' happening, and changing a webpage is one example of such an event. (Events are roughly C#'s equivalent of C++'s function pointers if that helps your understanding at all. Though they are more akin to a std::vector of function pointers.)

Set the HTML title tag for the page text contained within the two tags will show up in the tab that the web page is displayed in.
See the following for more about setting the title in the code behind
