Topic: Return Drawing Preview to a listView Control c#

[matinau]

Really hope you can help,
I've been scouring the net trying to find a simple method to return an image to a listview with little success. How can I use the ReadDWGFile to send the associated dwg "bitmap" to a listview using c#. Currently my code only returns the filePath.

I found this on your site but couldn't get it to work

private void AddToImageList(string filename)
        {
            Database db = new Database(false, false);
            db.ReadDwgFile(filename, FileOpenMode.OpenForReadAndAllShare, false, null);
            Bitmap bitmap = db.ThumbnailBitmap;
            if (!(imgListLarge.Images.ContainsKey(filename)))
            {
                imgListLarge.Images.Add(filename, bitmap);
                imgListSmall.Images.Add(filename, bitmap);

            }
        }

...here's hoping

Code - vb.net: [Select]

1.         Dim lv As ListView = your listview
2.         Dim il As New ImageList
3.  
4.         'Then add your bitmaps into your imagelist...
5.  
6.         Dim lvi As ListViewItem
7.         lv.MultiSelect = False
8.         lv.LargeImageList = il
9.  
10.         For i = 0 To il.Images.Count - 1
11.             lvi = New ListViewItem(enter name, i)
12.             lv.Items.Add(lvi)
13.         Next i
14.  

You can use an imagelist. Hope that helps.

legend! thank you. That worked but the image quality is pretty poor? Any tips? I've played around with ColorDepth property and ImageSize but there's still room for improvement.
