Customization censored in textBox

I have problem, which consists in aesthetic sense, correctly - There is textBox to which i apply true condition of UseSystemPasswordChar.. It's work! But i get bold points. Try to change font size - decreases textbox's field. Below is the code (although why is it here?). Can anyone help, thank you in advance)
public partial class frmRegistr : Form
{
public frmRegistr()
{
InitializeComponent();
}
int counter = 0;
int a = 0;
string b;
private void frmRegistr_Load(object sender, EventArgs e)
{
b = label1.Text;
a = b.Length;
label1.Text = "";
timer1.Start();
}
private void label1_Click(object sender, EventArgs e)
{
}
private void label2_Click(object sender, EventArgs e)
{
}
private void timer1_Tick(object sender, EventArgs e)
{
if (counter < a)
{
counter++;
label1.Text = b.Substring(0, counter);
}
else
{
timer1.Stop();
}
}
private void label4_Click(object sender, EventArgs e)
{
timer3.Start();
}
private void label4_MouseHover(object sender, EventArgs e)
{
//if this.MouseLeave
label4.BackColor = Color.FromArgb(((int)(((byte)(154)))), ((int)(((byte)(181)))), ((int)(((byte)(101)))));
}
private void timer2_Tick(object sender, EventArgs e)
{
if (Opacity == 1)
{
timer2.Stop();
}
Opacity += .2;
}
private void timer3_Tick(object sender, EventArgs e)
{
if (Opacity <= 0)
{
this.Close();
}
Opacity -= .2;
}
private void textBox2_TextChanged(object sender, EventArgs e)
{
textBox2.UseSystemPasswordChar = true;
}
}
}

If you want to define your own password character, use property TextBox.PasswordChar. If you want this in a certain font, use Control.Font
As you only have to do this once, do this in the constructor:
public MyForm : Form
{
InitializeComponents(),
this.textBox1.PasswordChar = '_';
this.textBox11.Font = new Font(...)
};
You can also decide to do this using the visual studio designer.

You can setup this in VisualStudio designer, but this is code:
textBox1.PasswordChar = '*';
//* = password character

How to set a counter and increment 1 every 3 second and display it in label

private void timer3_Tick(object sender, EventArgs e)
{
}

Here is the full code to do that. Just add a Label named "label1" on your window.
public partial class Form1 : Form
{
private Timer timer3;
private int counter;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
counter = 0;
timer3 = new Timer();
timer3.Interval = 3000;
timer3.Tick += Timer3_Tick;
timer3.Start();
}
private void Timer3_Tick(object sender, EventArgs e)
{
counter++;
label1.Text = counter.ToString();
}
}

increment the textbox using multithreading

I want to create a C# form in which two text box show two different numbers.
After clicking on start button both numbers should start incrementing at same time should increment slowly so we can see them increment and clicking on stop button should stop increment.
Both text box are not related to each other any way.
public partial class Form1 : Form
{
Thread t1 = new Thread(new ThreadStart(increment1));
public static int fNumber = 0, sNumber = 0,flag = 0;
public Form1()
{
InitializeComponent();
}
private void Start_Click(object sender, EventArgs e)
{
t1.Start();
}
private void button4_Click(object sender, EventArgs e)
{
}
private void number1_TextChanged(object sender, EventArgs e)
{
}
private void Form1_Load(object sender, EventArgs e)
{
}
public static void increment1()
{
Form1 frm = new Form1();
for (int i = fNumber;i<1000;i++)
{
frm.number1.Text = Convert.ToString(i);
}
}
}

public void Increment1()
{
for (int i = fNumber;i<1000;i++)
{
number1.Text = Convert.ToString(i);
number2.Text = Convert.ToString(i);
}
}
And just generally avoid static for threads. You can access your textboxes directly without the word this if you named your textboses number1 and number2. In a static method the variables need to be static aswell or you will get a compilation error.
For visibility, functions should have first letter in upper case. So you can distinguish them more easily from variables.

You are creating a new instance of Form1 which is wrong. Use the current Form1 that started the Thread.
Try
public partial class Form1 : Form
{
private Timer timer1;
public static int fNumber = 0, sNumber = 0,flag = 0;
public Form1()
{
timer1 = new Timer();
timer1.Interval = 1000;
timer1.Tick += timer1_Tick;
InitializeComponent();
}
private void Start_Click(object sender, EventArgs e)
{
timer1.Start();
}
private void button4_Click(object sender, EventArgs e)
{
timer1.Stop();
}
private void number1_TextChanged(object sender, EventArgs e)
{
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void timer1_Tick(object sender, EventArgs e)
{
int i = 0;
int.TryParse(this.number1.Text, out i);
i++;
if(this.number1.InvokeRequired)
{
this.number1.BeginInvoke((MethodInvoker) delegate()
{
this.number1.Text = Convert.ToString(i);
});
}
else
{
this.number1.Text = Convert.ToString(i);
}
}
}
For safety measures, check if invoking is required.
Replace this.number1.Text = Convert.ToString(i); with this block of code.
if(this.number1.InvokeRequired)
{
this.number1.BeginInvoke((MethodInvoker) delegate()
{
this.number1.Text = Convert.ToString(i);
});
}
else
{
this.number1.Text = Convert.ToString(i);
}

How to abort a while loop by clicking a button using C#

I have a function that displays numbers using a while loop but I want to stop execution of a while loop at random variable value using c# by clicking a button.
For Example:
private void FrqSent()
{
int i = 1;
while (i <= 5)
{
i = i + 1;
}
}

Here is a quick example on how you can use a Backgroundworker to accomplish your task:
public partial class Form1 : Form
{
private int i = 1;
public Form1()
{
InitializeComponent();
}
private void FrqSent()
{
while (i <= 500000000)
{
if (backgroundWorker1.CancellationPending)
{
break;
}
else
{
i = i + 1;
}
}
}
private void button1_Click(object sender, EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
private void button2_Click(object sender, EventArgs e)
{
backgroundWorker1.CancelAsync();
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
FrqSent();
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
MessageBox.Show(i.ToString());
}
}
Just create a new Windows-Forms Project and add a backgroundworker object aswell as 2 buttons. You have to set the DoWork, RunWorkerCompleted and Click events manually.
Edit: Do not forget to set the BackgroundWorker`s WorkerSupportsCancellation property to true.

not very elegant but simple
public partial class Form1 : Form
{
private bool _stop;
public Form1()
{
InitializeComponent();
}
private void buttonStart_Click(object sender, EventArgs e)
{
_stop = false;
FrqSent();
}
private void buttonStop_Click(object sender, EventArgs e)
{
_stop = true;
}
private void FrqSent()
{
int i = 1;
while (i <= 5000000 && !_stop)
{
i = i + 1;
Application.DoEvents();
}
}
}

}
private void button1_Click(object sender, EventArgs e)
{
do
{
axMozillaBrowser1.Navigate(textBox1.Text);
while(axMozillaBrowser1.ReadyState != MOZILLACONTROLLib.tagREADYSTATE.READYSTATE_COMPLETE)
{
Application.DoEvents();
if (axMozillaBrowser1.ReadyState == MOZILLACONTROLLib.tagREADYSTATE.READYSTATE_COMPLETE)
{
progressBar1.Value = progressBar1.Value + 1;
