Windows Thumbnail ControlI need to have a thumbnail control on a windows form. I've tried a few
activex thumbnail utilities. The best I have used so far is this one: http://viscomsoft.com/products/imagethumbnailcp/ The problem though is that the refresh is really slow. Has anyone had experience in writing their own thumbnail control or found any other useful activex controls that can by used in vb.net 2005? Thanks! Dustin Dustin, can't you just use
Dim bmpThumb As New Bitmap("yourfilename.jpg") bmpThumb.GetThumbnailImage() to get thumbnails? Then just show them? Why would you need or want a control? Seems like a lot of overhead. What do you want to display the thumbnails in a ListView? If so, why not do the above for all image files in a directory, add them to an ImageList control, attached to the listview and show them that way?
