Comments

The GetVirtualUserData function returns the application defined value last used in the SFTTREE_VIRTUALDEF structure when VirtualInitialize was called.

GetVirtualUserData provides the mechanism to retrieve the application defined value last used in the SFTTREE_VIRTUALDEF structure when VirtualInitialize was called. This is usually used when only the tree control window handle or window object is known, and the application needs the value so it can access additional application specific information.
