C# edit property of panel using run-time generated button

I'm a complete noob in C# programming. This is my problem: I have a form with a panel that is generated upon clicking button 1, the panel also containes a button (btnColor1) to change the backcolor of the panel. I would like to refer to the panel's backcolor in btnColor1, but I get the error "The name 'btnColor1' does not exist in the current context". How can I fix this?
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 TEST_APP_1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Panel myPanel1 = new Panel();
myPanel1.Location = new System.Drawing.Point(100, 50);
myPanel1.Name = "Panel 1";
myPanel1.Size = new System.Drawing.Size(200, 100);
myPanel1.BackColor = Color.Red;
TextBox textBox1 = new TextBox();
textBox1.Location = new Point(10, 50);
textBox1.Text = "empty field";
textBox1.Size = new Size(150, 30);
Button btnColor1 = new Button();
btnColor1.Location = new Point(10, 10);
btnColor1.Text = "GOLD";
btnColor1.Size = new Size(100, 30);
btnColor1.Click += myButton1_Click;
myPanel1.Controls.Add(textBox1);
myPanel1.Controls.Add(btnColor1);
Controls.Add(myPanel1);
}
private void myButton1_Click(object sender, EventArgs e)
{
throw new NotImplementedException();
btnColor1.BackColor = Color.Gold;
}
}
}

btnColor1 is declared in the scope of the button1_Click method so does not exist as a variable to reference in your event handler. Change the event handler to this:
private void myButton1_Click(object sender, EventArgs e)
{
throw new NotImplementedException();
(sender as Button).BackColor = Color.Gold;
}

You can try to use the parent property of the button to access the panel and the form:
private void myButton1_Click(object sender, EventArgs e)
{
Button but = (sender as Button);
but.BackColor = Color.Gold;
// this changes the color of the panel
but.Parent.BackColor = Color.Gold;
// this changes the color of the form containing the panel
if (but.Parent.Parent != null)
{
but.Parent.Parent.BackColor = Color.Gold;
}
}

AForge Convertation and problems with HD

First of all, I can't play and record HD video(1920x1080), when I change my camera resolution to 1920x1080 program show and record black background, if camera resolution is 720x576 it works without problems. I'm sure that the problem is in my solution because, when I use DesktopVideo(Software which is included with Blackmagic Decklink Studio 2) it shows HD video from camera.
Second, How do I convert video with AForge? like changing resolution and framerate, I can change codecs and bitrate, but when I change Resolution and FrameRate in "FileWriter.Open"
command I get Error Resolution and FrameRate must be the same as Bitmap I'm capturing from camera.
If anybody knows how to solve these problems please share information, thanks!

The provided code simply captures and saves in the format currently active/selected for the capture device. In general, resolution change is an "expensive" operation is not available as a complimentary operation.
You want to change resolution right on capture device by switching it to more appropriate format, then capture in this resolution and have all further data manipulation in correct resolution. Available resolutions and options might be hardware specific there.
If/when no suitable capture resolution option is available, you typically resample the video to new resolution. Even though Windows API has suitable functionality, in your particular case you are interested to have this integrated with AForge library and you need to check its documentation to find out whether it provides a respective wrapper and whether it can be integrated into capture process overall (or, you need to write this code yourself to handle scaling).

Display an image into windows forms

I wanted to display an image to the windows forms, but i already did this and the image did not come out.
Where did I go wrong?
Here is the code:
private void Images(object sender, EventArgs e)
{
PictureBox pb1 = new PictureBox();
pb1.Image = Image.FromFile("../SamuderaJayaMotor.png");
pb1.Location = new Point(100, 100);
pb1.Size = new Size(500, 500);
this.Controls.Add(pb1);
}

Here (http://www.dotnetperls.com/picturebox) there 3 ways to do this:
Like you are doing.
Using ImageLocation property of the PictureBox like:
private void Form1_Load(object sender, EventArgs e)
{
PictureBox pb1 = new PictureBox();
pb1.ImageLocation = "../SamuderaJayaMotor.png";
pb1.SizeMode = PictureBoxSizeMode.AutoSize;
}
Using an image from the web like:
private void Form1_Load(object sender, EventArgs e)
{
PictureBox pb1 = new PictureBox();
pb1.ImageLocation = "http://www.dotnetperls.com/favicon.ico";
pb1.SizeMode = PictureBoxSizeMode.AutoSize;
}
And please, be sure that "../SamuderaJayaMotor.png" is the correct path of the image that you are using.

There could be many reasons for this. A few that come up quickly to my mind:
Did you call this routine AFTER InitializeComponent()?
Is the path syntax you are using correct? Does it work if you try it in the debugger? Try using backslash (\) instead of Slash (/) and see.
This may be due to side-effects of some other code in your form. Try using the same code in a blank Form (with just the constructor and this function) and check.

I display images in windows forms when I put it in Load event like this:
private void Form1_Load( object sender , EventArgs e )
{
pictureBox1.ImageLocation = "./image.png"; //path to image
pictureBox1.SizeMode = PictureBoxSizeMode.AutoSize;
}

private void Form1_Load(object sender, EventArgs e)
{
PictureBox pb = new PictureBox();
pb.Location = new Point(0, 0);
pb.Size = new Size(150, 150);
pb.Image = Image.FromFile("E:\\Wallpaper (204).jpg");
pb.Visible = true;
this.Controls.Add(pb);
}

Saving images using Aforge

i wrote a code for accessing webcam and on clicking, saving the picture to a folder.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using AForge.Imaging;
using AForge.Imaging.Filters;
using AForge.Video;
using AForge.Video.DirectShow;
namespace cam
{
public partial class Form1 : Form
{
public static Bitmap _latestFrame;
public Form1()
{
InitializeComponent();
}
private FilterInfoCollection webcam;
private VideoCaptureDevice cam;
Bitmap bitmap;
private void Form1_Load(object sender, EventArgs e)
{
webcam = new FilterInfoCollection(FilterCategory.VideoInputDevice);
foreach (FilterInfo VideoCaptureDevice in webcam)
{
comboBox1.Items.Add(VideoCaptureDevice.Name);
}
comboBox1.SelectedIndex = 0;
}
private void button1_Click(object sender, EventArgs e)
{
cam = new VideoCaptureDevice(webcam[comboBox1.SelectedIndex].MonikerString);
cam.NewFrame += new NewFrameEventHandler(cam_NewFrame);
cam.Start();
}
void cam_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
bitmap = (Bitmap)eventArgs.Frame.Clone();
pictureBox1.Image = bitmap;
}
private void pictureBox1_Click(object sender, EventArgs e)
{
pictureBox1.Image = bitmap;
}
private void button3_Click(object sender, EventArgs e)
{
if (cam.IsRunning)
{
cam.Stop();
}
}
private void button2_Click(object sender, EventArgs e)
{
Bitmap current = (Bitmap)_latestFrame.Clone();
string ActiveDir = AppDomain.CurrentDomain.BaseDirectory;
string filepath = System.IO.Path.Combine(ActiveDir, #"D://picture/");
if (!System.IO.Directory.Exists(filepath))
{
System.IO.DirectoryInfo OutputDir = System.IO.Directory.CreateDirectory(filepath);
string fileName = System.IO.Path.Combine(filepath, #"name.bmp");
if (!System.IO.File.Exists(fileName))
{
current.Save(fileName);
}
}
current.Dispose();
}
}
}
In the button2 I have written the code for saving the picture, on building the program, an null reference exception is shown for the given line(Bitmap current = (Bitmap)_latestFrame.Clone();)

As far as I can see in your code, the new image frame is copied to your member variable bitmap. The static member _latestFrame never seem to be assigned.
Therefore, in your button2_Click method, change the first line to:
Bitmap current = (Bitmap)bitmap.Clone();
Now, provided you have received at least one frame from the webcam when you click the button, the frame should be properly saved.
I also think you are overworking the filepath setting in the button2_Click method. To begin with, simply verify that the picture can be properly saved to the active directory by changing your button2_Click method to this:
private void button2_Click(object sender, EventArgs e)
{
Bitmap current = (Bitmap)bitmap.Clone();
string filepath = Environment.CurrentDirectory;
string fileName = System.IO.Path.Combine(filepath, #"name.bmp");
current.Save(fileName);
current.Dispose();
}
This will ensure that a new image will be written to the "current directory" every time you click on the Capture button.
I have tested your code with the above changes, and it works flawlessly.
