Adding Scanned Images in ListView

Question

I am scanning the images via WIA and saving the images in List. What I want is, I want to save the get the images from the list and show them in the listview. But I am getting a strange problem. When I click Scan button in my c# window application my list saves only latest image and my List counter doesn't increases to 2 it always remains 1. So my list only save the latest image and overwrite the previous image. Here is my code when I click Scan Button:

            List<Image> images = WIAScanner.Scan((string)lbDevices.SelectedItem);
            ImageList imageList1 = new ImageList();

            foreach (Image image in images)
            {
                pictureBox.Image = image;

                imageList1.Images.Add(image);

            }

                this.listView1.View = View.LargeIcon;
                imageList1.ImageSize = new Size(90, 90);
                listView1.LargeImageList = imageList1;

                for (int j = 0; j < imageList1.Images.Count; j++)
                {
                    ListViewItem item = new ListViewItem();
                    item.ImageIndex = j;
                    this.listView1.Items.Add(item);
                }

I suppose the code you posted, is the code which is lying behind your scan button's click event. If so, put the following line out of the click event.

ImageList imageList1 = new ImageList();

With this line you will reset your ImageList, everytime you start a new scan. Put this line outside your click method and all should be fine.

yup it works! but having another problem now. it is now doubling thw images because of this line imageList1.Images.Add(image); while looping – Fahad Murtaza Jul 04 '13 at 12:17
Put a `this.listView1.Items.Clear();` before the "for-loop" where you fill your list. ;) Would you please accept my answer. ;) – netblognet Jul 04 '13 at 12:27
