Problems with Image Tag in Picturebox

So, i try to learn how to Drag and Drop an Image from one PictureBox to another and that works well. But how can i drag and drop the Image TAG from pictureox1 to picturebox2?
i currently have 3 source images and 3 drop boxes.
the dropbox6 is locked with a countdown after a buttonclick (see button2)
(later i will lock all dropboxes)
after i hit this button a countdown starts and if the countdown is 0 (ZERO) only then i can drag one of the 3 images to this box.
however, i have given each of these 3 images in the souceboxes a TAG name.
how can i drop this tagname also to the dropbox?
here is what i have so far:
(the Label labeled "Counter" is actually Label4 in the code

In MouseDown you are saying what you want to transmit in the DoDragDrop call. In your current case you are transmitting the image ((PictureBox)sender).Image but you can chose to transmit the tag as well...
private void pictureBox_MouseDown(object sender, MouseEventArgs e)
{
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Image, DragDropEffects.Copy);
((PictureBox)sender).DoDragDrop(((PictureBox)sender).Tag, DragDropEffects.Copy);
}
...Then make sure to parse for each possible input type in DragDrop
private void pictureBox6_DragDrop(object sender, DragEventArgs e)
{
var image = e.Data.GetData(DataFormats.Bitmap) as Bitmap;
var tag = e.Data.GetData(DataFormats.Text) as string;
if (image != null)
{
pictureBox4.Image = image;
}
if (tag != null)
{
pictureBox4.Tag = tag;
}
timer1.Enabled = false;
}
Beware, that you will need to update all the code that checks that the data is Bitmap before it arrives at DragDrop ie in DragEnter and write code that handles both Bitmap and Text, otherwise the Drag functionality will break.

AWESOME!!
It works now. I will continue this Project.

Missing the User Control in Windows Form And the Tool Box?

Drawing a straight line in C# windows form

I have a simple windows forms program which allows the user to draw straight lines in a picture box. There is a line, but it goes out of the picture box and is not visible within it (like in the picture i attached). How can i make it so line shows up only in the picture box. Here is my 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;
using System.Windows.Input;
namespace LinePOD
{
public partial class LineTest : Form
{
public LineTest()
{
InitializeComponent();
}
Point p1 = new Point();
Point p2 = new Point();
Pen pen = new Pen(Color.Magenta, 10);
private void LineTest_Load(object sender, EventArgs e)
{
}
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
p1 = e.Location;
}
private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
p2 = e.Location;
Graphics g = this.CreateGraphics();
g.DrawLine(pen, p1, p2);
}
}
private void pictureBox1_Click(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
pictureBox1.BackColor = Color.Aqua;
}
}
}

You may create a bitmap with same size of PictureBox and draw that bitmap in the Paint event of PictureBox. Then draw lines to bitmap in your mouse events. This retains lines in windows minimize/restore events. I put entire code for convenience:
public partial class Form1 : Form
{
Bitmap bitmap;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
bitmap = new Bitmap(pictureBox1.ClientSize.Width,
pictureBox1.ClientSize.Height,
System.Drawing.Imaging.PixelFormat.Format32bppArgb);
}
Point p1 = new Point();
Point p2 = new Point();
Pen pen = new Pen(Color.Magenta, 10);
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
p1 = e.Location;
}
private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
p2 = e.Location;
Graphics g = Graphics.FromImage(bitmap);
g.DrawLine(pen, p1, p2);
pictureBox1.Invalidate();
g.Dispose();
}
}
private void button1_Click(object sender, EventArgs e)
{
pictureBox1.BackColor = Color.Aqua;
}
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
e.Graphics.DrawImage(bitmap, 0, 0, bitmap.Width, bitmap.Height);
}
}

change brush color with combobox

I need the comboBox index to change the color of the brush/pen when it is selected, I know it should be a simple fix, but I cant seem to get it.
public partial class Form1 : Form
{
private bool penDown = false;
private int radius = 5;
private SolidBrush brush = new SolidBrush(Color.IndianRed);
private Color[] colors = { Color.IndianRed, Color.Blue, Color.Green, Color.Yellow, Color.Purple};
public Form1()
{
InitializeComponent();
}
private void btnClr_Click(object sender, EventArgs e)
{
Graphics g = panel1.CreateGraphics();
g.Clear(panel1.BackColor);
g.DrawImage(panel1.BackgroundImage, panel1.ClientRectangle, 0, 0, panel1.BackgroundImage.Width,
panel1.BackgroundImage.Height, GraphicsUnit.Pixel);
g.Dispose();
}
private void btnQuit_Click(object sender, EventArgs e)
{
base.Close();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
if (!penDown)
{
return;
}
Graphics g = panel1.CreateGraphics();
g.FillEllipse(brush, new Rectangle(e.X - radius, e.Y - radius, 2 * radius, 2 * radius));
g.Dispose();
}
private void panel1_MouseDown(object sender, MouseEventArgs e)
{
penDown = true;
}
private void panel1_MouseUp(object sender, MouseEventArgs e)
{
penDown = false;
}
private void colorCB_SelectedIndexChanged(object sender, EventArgs e)
{
//int i = ((color
}
}

Just use the combo box SelectedIndex property to retrieve the color from your colors array:
private void colorCB_SelectedIndexChanged(object sender, EventArgs e)
{
brush = new SolidBrush(colors[colorCB.SelectedIndex]);
}

How can I add (append) a word to the same sentence, using one button (click) per word

I greatly appreciate any help. I have 20+ buttons, each with a word, or a space or period. Each time I click on a button, the pre-existing word is wiped out and replaced with the new word. I need each word and/or space to remain in place until I click the "Clear" button.
Maybe this has been previously asked/answered under different search terms? I tend to believe I need to identify a string variable, but have no idea how to begin.

Use lb1SentenceText.Text+=whatever.Text;.
+= is equivalent to lbSentence.Text = lblSentenceText.Text + whatever.Text.
Basically, it appends or concatenates the right hand side string to the string on the left hand side. Hope it makes sense?
So:
string rhs="Hello " ;
string lhs = "World";
string rhs = rhs + lhs;//Hello World

Please be inspired. You have a lot of redundant code.
btnA.Click += AppendButtonText;
btn_a.Click += AppendButtonText;
...
private void AppendButtonText(object sender, EventArgs e)
{
var button = sender as Button;
if (button != null)
{
lblSentenceText.Text += button.Text;
}
}

On the button click events, change it to += instead of = (except in the clear button). This is equivalent to writing something = something + newValue;.

Try:
lb1SentenceText.Text = lb1SentenceText.Text + *something*.text
The += operator means add to, and the variable modified is equal to the added (Int, String) appended to the original value (x = 1; x += 3; x is now 4)
Try this:
button.Click += new System.EventHandler(ButtonClick);
button1.Click += new System.EventHandler(ButtonClick);
// And for each button, one of those.
private void ButtonClick(object sender, System.EventArgs e)
{
// Do whatever you want to do here, you can place the TEXT to be appended on the button, if so:
lb1SentenceText.Text += sender.Text;
}

//Simple.Create a global variable and within each button click event do this;
string yourStrVar = ""; //Must be global
yourStrVar+= ((Button)sender).Text
