Thumbnail property (LEADDlgFile Control)
Remarks
Gets or sets a handle to a thumbnail image used by the Open dialog box.
This property will be updated with the file's thumbnail bitmap if DLG_OPEN_GENERATETHUMBNAIL
is set in the DlgFlags property.
You can assign 0 to this property to free the existing thumbnail bitmap.
If you set DLG_OPEN_ALLOWMULTI flag in the DlgFileFlags property, and
DLG_OPEN_GENERATETHUMBNAIL in the DlgFlags
property, this property will be valid only during the OnOpenFileEvent
event. For each OnOpenFileEvent event that occurs this property will contain
one of the selected (loaded) file’s thumbnails. The OnOpenFileEvent event
will occur for each of the selected files opened using the Open dialog
box. In this case you can’t assign this property to 0.
