Hi all, What is a maximum size of ImageList and what is a maximum value of icon index of TreeView node? There is a TreeView control that uses ImageList. ImageList contains about 80.000 pictures. When node with icon index > 0xFFFF is added to TreeView it shows other icon. I think the reason is a WORD number overflow, but I've not found any limitation of used things - MSDN says icon index and ImageList size are int values, so they should work with values > 0xFFFF too.
