If an exception handler that can handle the type of the exception object is found, the exception handler chosen is said to "catch" the exception. If the runtime system cannot find an appropriate exception handler even after searching through the entire call stack, the operating system generates ...
Exception handling is useful for dealing with exceptions that cannot be handled locally. Instead of showing an error status in the program, theexception handlertransfers control to where the error can be handled. A function can throw exceptions or can choose to handle exceptions. Error handling cod...
When an appropriate handler is found, the runtime system passes the exception to the handler. An exception handler is considered appropriate if the type of the exception object thrown matches the type that can be handled by the handler. The exception handler chosen is said tocatch the exception...

An exception is also known as a fault. Techopedia Explains Exception As a part of every well structured software or hardware appliance, an exception may be classified as one of two broad types: predefined and user defined. Predefined exceptions are native to a system and generally occur when a...
ExceptionDispatchInfoError handling is an important aspect in building framework components. Sometimes re-throwing exceptions (in C# via “throw;”) is not sufficient, because it can only happen within an exception handler. Some framework components, such as the Task infrastructure, have...
The simplest way to think of an event is as asignal. This signal is fired every time a user interacts with a program. When this happens, the operating system orbrowsermust be notified of the resultant changes and the program must respond appropriately. Here's where an event handler -- spe...
If an exception is thrown out ofBlock1, C++ looks for a matchingcatchblock,¹ and neither clause matches, then the search for a handler continues at the next outer scope. If no scope handles the exception, then the process terminates viastd::terminate. ...
The metabase for IIS 6.0 is stored in an XML file instead of in binary format as it was in earlier versions of IIS. The location remains the same, but the ways it can be manipulated -- updated, rolled back, restored, and extended -- have changed. There are two significant files ...
The client can also subscribe an event handler to the <operation>Completed event, to have that handler called upon completion. The big difference using <operation>Async as opposed to Begin<operation> is that the <operation>Async methods will pick up the synchronization context of the client and...
