I'm writing a scanning app and the toolkit I'm using is EMC Captiva(Pixtools).
I have this line of code....
Dim imageNode As PixImageNode = TryCast(e.ThumbnailNode.DocNode, PixImageNode)
On my form I have a pixview which displays a large image of the selected scanned image and then I have a thumbnailview which shows a little node of each scanned image that you can click on to view in the pixview. So basically this line of code allows you to click on a node and that's what is displayed in the pixview. My problem is when you click on a node and hit the delete key (because maybe the scanned image looks bad) the program crashes. I have tried to check if everything was null do this or that but its not working because you click on the image it displays it, then you delete it and its gone so it doesn't know what it should display... I can't change that line of code otherwise it wont do what I need it to do....any ideas?
