IErrorCollection Interface

Provides access to members that control an Error Collection.


Unlike exceptions thrown within a program, COM exceptions do not stop the flow of execution; instead, a COM error object is created within the current thread. The error object supports the IErrorInfo interface, which has methods allowing the client to get the name of the class and interface which created the error, and a description of the error.

QI from IErrorInfo to IErrorCollection.

See the Error Handling in Components topics for more details.
