how to show file icons in list view control?
-
Hi, all. I study C# programming about list view control. and I would like to show file icons on the list view control, when I drag & drop some files. I could show file paths on list view control though. but I can't show file icons.
string[] files = (string[])e.Data.GetData(DataFormats.FileDrop); foreach (string file in files) { Icon ico = Icon.ExtractAssociatedIcon(@file); Image img = ico.ToBitmap(); ListViewItem lvi = new ListViewItem(); lvi.Text = ""; lvi.ImageList.Images.Add(img);// this line has an error. // I would like to show file icons on this list view control , when I drag & drop some files. // I can show file paths when I drag & drop on the control though.listView1.Items.Add(file); }Thanks.:) -

Originally, I did that way. even though I removed @, an error occured. like this: First exception of 'System.NullReferenceException' format is occured from StackDocklet.exe.

Perhaps the ImageList is null? The times that I've used file icons in a ListView, I added the images to the ImageList, then set the image index of a ListViewItem accordingly. Of course, you need to set the ListView.ImageList property to the aforementioned ImageList

that mean 'StackDocklet.exe' do not have any icon...

the ImageList value is null. You can try this:
string s= "1.txt"; Icon i = Icon.ExtractAssociatedIcon( s ); ImageList imageList = new ImageList(); imageList.Images.Add(i); this.listView1.SmallImageList = imageList; this.listView1.Items.Add(new ListViewItem(s, 0));Hope this will help you~:) I Love KongFu~
