I have a program that allows drag and drop into the panel (Picturebox).

How am i to ensure that this picturebox only be dropped into the panel and no where else?

public Form1()
        {
            InitializeComponent();
            string ImagePath = Application.StartupPath + @"\\Model Products v3\";

            //   string[] Images = new string[] { ImagePath + "FingerprintScanner1Button.jpg", ImagePath + "FingerprintScanner2Button.jpg", ImagePath + "FingerprintScanner3Button.jpg" };
            string[] Images = new string[] { ImagePath + "FingerprintScanner1Button.jpg" };






            foreach (string img in Images)
            {
                PictureBox PB = new PictureBox();
               
                PB.Width = PB.Height = 43;
                PB.Location = new Point(38, 13);
                PB.Image = Image.FromFile(img);
                PB.MouseDown += new MouseEventHandler(PB_MouseDown);
                PB.MouseHover += new System.EventHandler(PB_MouseHover);
                PB.MouseLeave += new System.EventHandler(PB_MouseLeave);
            
                this.Controls.Add(PB);



            }

           
        }

      


        void PB_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                x = e.X;
                y = e.Y;


                PictureBox pictureBox = new PictureBox();
                pictureBox.Image = ((PictureBox)sender).Image;
               
                pictureBox.Top = ((PictureBox)sender).Top;
                pictureBox.Width = ((PictureBox)sender).Width;
                pictureBox.Height = ((PictureBox)sender).Height;
                pictureBox.Left = ((PictureBox)sender).Left;
                pictureBox.MouseMove += new MouseEventHandler(PictureBox_MouseMove);
                pictureBox.MouseDown += new MouseEventHandler(pictureBox_MouseDown);
                this.Controls.Add(pictureBox);
                pictureBox.BringToFront();

                MouseUPDOWN();

             

            }
        }


     
        void PB_MouseHover(object sender, System.EventArgs e)
        {
            mouseLocation = this.PointToClient(Cursor.Position);
            pictureBox1.Location = mouseLocation;
            pictureBox1.Show();
            pictureBox1.BringToFront();


        }

        void PB_MouseLeave(object sender, System.EventArgs e)
        {
            pictureBox1.Hide();
        }

        void PB1_MouseHover(object sender, System.EventArgs e)
        {
            mouseLocation = this.PointToClient(Cursor.Position);
            pictureBox2.Location = mouseLocation;
            pictureBox2.Show();
            pictureBox2.BringToFront();
        }


        void pictureBox_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                x = e.X;
                y = e.Y;
            }
        }

       

        void PictureBox_MouseMove(object sender, MouseEventArgs e)
        {
           
           if (e.Button == MouseButtons.Left)
           {

                ((PictureBox)sender).Left += (e.X - x);
                ((PictureBox)sender).Top += (e.Y - y);
                ((PictureBox)sender).BringToFront();
           }
        }

        


   

        #region MouseAPIs
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);

        private const int MOUSEEVENTF_LEFTDOWN = 0x02;
        private const int MOUSEEVENTF_LEFTUP = 0x04;
        private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
        private const int MOUSEEVENTF_RIGHTUP = 0x10;

        public void MouseUPDOWN()
        {
            mouse_event(MOUSEEVENTF_LEFTUP, Cursor.Position.X, Cursor.Position.Y, 0, 0);
            mouse_event(MOUSEEVENTF_LEFTDOWN, Cursor.Position.X, Cursor.Position.Y, 0, 0);
        }
        #endregion

      

       
        }

Hi,

the drag and drop has no issue.

I only want to assure that the drag and drop is only DROPPED INTO THE DESIGNED PANEL AND NO WHERE ELSE.

thank u (:
