PRB: Class Browser: "Unable to Display Class Hierarchy" ErrorLast reviewed: September 17, 1995Article ID: Q136848 |
The information in this article applies to:
SYMPTOMSWhen a Class library is browsed in the Class Browser and a class that has subclasses is removed, the error "Unable to Display Class Hierarchy" is displayed when the Class Browser form is refreshed.
CAUSEA class contains an explicit reference to its parent in a .vcx file. If the parent class is removed, the derived class cannot find its parent, and the class hierarchy is incorrect.
RESOLUTIONRemove the child classes first, and then delete the parent class.
STATUSThis behavior is by design.
