If you are using the Thumbnail Browser control of LEADTOOLS 14.5 or earlier, this control does not display anything. It only browses the returns the images.

You must assign the returned bitmap to a different control, such as a LEAD Main OCX or an Image List control to display them.

You can do that inside the ThumbnailEvent when it is triggered with nStatusCode = 0 (which means the function was successful).
