Hi,

can anyone help me on this. I'have put pictureBox in panel, with image loaded into pictureBox. When scrolling, I want to load another pictureBox on certain position within panel, that will be displayed along original pictureBox. I'm having trouble with this.

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
      {
          if (e.Button == MouseButtons.Left)
          {
              X = e.X;
              Y = e.Y;
          }
      }

      private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
      {
          if (e.Button == MouseButtons.Left)
          {
              pictureBox1.Left += (e.X - X);
              pictureBox1.Top += (e.Y - Y);
              txtX.Text = "e.X: " + e.X + ",X: " + X_k.ToString();
              txtY.Text = "e.Y: " + e.Y + ",Y: " + Y_k.ToString();
              
              if (Y_k>=7404800)
              {
                  PictureBox pictureBox3 = new PictureBox();
                  pictureBox3.Image = new Bitmap("\\Program Files\\Karta\\maps\\Nikinci_0_0000_0001.GIF");
                  pictureBox3.Location = new Point(e.X,e.Y);
                  pictureBox3.Size = new Size(pictureBox3.Image.Width, pictureBox3.Image.Height);
                  panel1.Controls.Add(pictureBox3);
                  //pictureBox3.MouseDown+=new MouseEventHandler(pictureBox3_MouseDown);
                  //pictureBox3.MouseMove+=new MouseEventHandler(pictureBox3_MouseMove);
                  pictureBox3.Show();
                                }
          
          }

pete,

Please use code tags when pasting code:

Also please follow up with your old threads. I answered your original question in the thread http://www.daniweb.com/forums/thread205618.html and suggested another way for image loading. Please mark your threads as solved if your question was answered if you would like to continue receiving help.

Next, for this problem. I have looked at a number of mapping applications and I think you should have arrows on the screen for up/down/left/right and do away with the scroll bars. Split your images up in to a lot of 25x25 or 50x50 image and as you scroll create empty picture placeholders and have a worker thread load the images as you scroll. If someone is scrolling fast and the image square goes out of view then stop loading the image and move on to the next images .. you will have a finite number of panels visible at one time depending on the device's display size and settings. If you try to load up a number of large images your performance will suffer. Take a look at google maps loads maps on their website and look at other similar applications for mobile devices. I used my iPhone. Notice how they have a grid on the background until the image loads then they replace the grid with the image.

awesome.

If I show you how to load images in a thread will that get you the information you need to complete this? This is getting complicated as hell real quick :(

Unfortunately, I think I'm having problem with both image loading and positioning/placing panels where to put images. Take your time, day or two won't harm.

Sorry buddy .. I still haven't had time to get around to this. I have a project I really need to get done and I was about to pop a blood vessel earlier today because I was getting so irritated. I have to get off the computer but this is still on my radar
