How to change label text and color when a condition is met? (C#)

I am making a password generator and on websites when you enter certain conditions are met the strength of the password changes how can I change the color and text of the label when the password strength is >= 8, <8<10, >12?
Here is the Code:
using System;
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 Password_Generator
{
public partial class PassGen : Form
{
int currentPasswordLength = 0;
Random Character = new Random();
private void PasswordGenerator(int PasswordLength)
{
String validChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!##$&?";
String randomPassword = "";
//25
for(int i = 0; i < PasswordLength; i++)
{
int randomNum = Character.Next(0, validChars.Length);
randomPassword += validChars[randomNum];
}
Password.Text = randomPassword;
}
public PassGen()
{
InitializeComponent();
PasswordLengthSlider.Minimum = 5;
PasswordLengthSlider.Maximum = 22;
PasswordGenerator(5);
}
private void Label1_Click(object sender, EventArgs e)
{
}
private void Copy_Click(object sender, EventArgs e)
{
Clipboard.SetText(Password.Text);
}
//52
private void PasswordLength_Click(object sender, EventArgs e)
{
}
private void PasswordLengthSlider_Scroll(object sender, EventArgs e)
{
PasswordLength.Text = "Password Length:" + " " + PasswordLengthSlider.Value.ToString();
currentPasswordLength = PasswordLengthSlider.Value;
PasswordGenerator(currentPasswordLength);
}
private void pswdStrengthTest()
{
if (currentPasswordLength <= 8)
{
pswdStrength.Text = "weak";
pswdStrength.ForeColor = Color.Red;
} else if (currentPasswordLength<= 9)
{
pswdStrength.Text = "ok";
pswdStrength.ForeColor = Color.Blue;
}
}
//78
private void pswdStrength_Click(object sender, EventArgs e)
{
}
}
}
If anyone could help me with this it would be greatly appreciated. This is based off a tutorial I found on YouTube. I'm not sure what the video is called but if it helps I could search for it and update my posting.

Try this:
Password.TextChanged += (s1, e1) =>
{
if (Password.Text.Length > 10)
pswdStrength.ForeColor = Color.Green
else if (Password.Text.Length > 8)
pswdStrength.ForeColor = Color.Blue
else
pswdStrength.ForeColor = Color.Red
};

Your code looks like a windows form application.
If you have for example one objetc txt_password, check to code some of these events:
TextChanged: this occurs when your textbox has been changed
Others events could be:
KeyPress or KeyDown

Array/String of dynamically created textBoxes in Visual Studio - C#

I created, dynamically, a number of textBoxes. The user will write input in those textBoxes and then press a button ("SAVE").
I want to save the info from those textBoxes in an array(or string). Is it possible to implement something like this: for(i = 0; i < the_number_of_textBoxes; i++) MY_ARRAY_or_MY_STRING += textBox[i].Text; //I know this isn't correct
I'm sure there should be something similar to my "way of thinking", but I can't find it.
If I would always have the same number of texboxes, lets say 2, I could implement it like this: MY_ARRAY_or_MY_STRING = textBox1.Text + textBox2.Text;, but my textBoxes are dynamicaly generated.
Here is the code I use (although I don't think it will be of need), my program has 2 Forms (Form1 is noted as frm1) - It has nothing to do with my question, but maybe it helps, idk. If you need more info about what the program does, ask away, I wont write it here, because it may be useless info.

Why is this code not displaying output on the textbox?

I am beginning with C#. When I run the following code and click the generate button the output does not appear in the textbox. Why is this? I am calling the function palendrome and its not updating the textbox. What am I doing wrong? Am I missing something? What do I need to fix. I don't see the error. Please help. :(

}
}

It is not generating any input on the textbox because your function palendrome is not generating in anyway output on any of textbox1 to textbox3.
Try this:
textBox1.Text = "output"; //Whatever output you want.

If you want to show result in textBox3 the code to update it's text property should be inside button click handler, not in text changed handler.
Also while (count != 0) or while (copyCount != 0) are like infinite loops (almost). They are going to make your form unresponsive. You need to avoid those.

How to save name that is entered in text box and the time that is on the timer when the game is completed

At the minute i have a match picture game in c# windows forms with a timer that stops when all matches are complete. I am wondering how do i save the time taken and the name that is entered using btn_player in a text file. The text file is stored at (#"E:\Match Picture\Public\Files\playerdetails.txt");
using System.Windows.Forms;
using System.Threading;
using System.IO;
namespace Match_Picture
{
public partial class Form1 : Form
{
string Temp_Tag = "";
int Number_of_Images = 0;
Label Clicked_Picture = new Label();
Label Temp_Pic = new Label();
int Num_Correct = 0;
public Form1()
{
InitializeComponent();
}
private void Picture_Click(object sender, EventArgs e)
{
Clicked_Picture = (Label)sender;
Number_of_Images++;
if (Number_of_Images < 3)
{
Clicked_Picture.Text = Clicked_Picture.Tag.ToString();
if (Number_of_Images == 1)
{
Temp_Tag = Clicked_Picture.Tag.ToString();
Temp_Pic = Clicked_Picture;
}
else
{
if (Temp_Tag != Clicked_Picture.Tag.ToString())
{
tmr_Delay.Enabled = true;
scorecounter.Text = Convert.ToString(Convert.ToInt32(scorecounter.Text) - 20);
}
else
{
Num_Correct++;
scorecounter.Text = Convert.ToString(Convert.ToInt32(scorecounter.Text) + 50);
lbl_Matches.Text = Num_Correct.ToString();
if (Num_Correct == 8)
{
tmr_1.Stop();
MessageBox.Show("Congratulations, all matches complete");
MessageBox.Show("Number of seconds to match all the pictures: " + i);
this.Close();
}
}
Number_of_Images = 0;
}
}
}
private void tmr_Delay_Tick(object sender, EventArgs e)
{
Clicked_Picture.Text = "R";
Temp_Pic.Text = "R";
tmr_Delay.Enabled = false;
}
int i = 0;
private void timer1_Tick(object sender, EventArgs e)
{
i++;
lbl_time.Text = i.ToString() ;
}
private void btn_player_Click(object sender, EventArgs e)
{
}

You can use the StreamWriter class in order to do what you need.
using (StreamWriter writer = new StreamWriter(#"E:\Match Picture\Public\Files\playerdetails.txt"))
{
writer.WriteLine("") // This is where you will write what you want to that file
}
As MethodMan, you can use EndTime - StartTime, and any other conversions necessary in order to get it in the format you want (minutes, seconds, etc).
This code will simply write to the text file. It will create it if it does not exists, and it will overwrite the file if it does exist. You need to do the proper checks to make sure that you don't overwrite it, or you can use
new StreamWriter(#"E:\Match Picture\Public\Files\playerdetails.txt", true)
if you want to append the file instead of overwriting. Full documentation of the StreamWriter class can be found here http://msdn.microsoft.com/en-us/library/system.io.streamwriter%28v=vs.110%29.aspx
As an aside, if you're trying to keep records of high score, you should also look into the StreamReader class. You can read in the file into a dictionary of Player and Time, and check to see if a player already exists in the file and only adjust their score if it beats their best score.

You say in your comment that you tried Thread.Sleep, and you're right: that will pause the currently executing thread for 3 seconds, which means your UI will stop responding for those 3 seconds.
What you might try instead is using a System.Windows.Forms.Timer, which can be started in your code where you want the delay to happen. It will then fire an event when your delay is complete, and your post-delay code should go in the event handler. This way, your delay can happen without affecting the UI.

I guess one way would be Thread.Sleep(3000);. There are a number of ways to do what you want, but based on the code you've provided, that should suffice. Place it where you want the delay.
