ShowException procedure
Show the current exception to the user.
Declaration
procedure ShowException(ExceptObject: TObject; ExceptAddr: Pointer)Description
ShowException shows a message stating that a
ExceptObject
was raised at address
ExceptAddr. It uses
ExceptionErrorMessage to create the message, and is aware of the fact
whether the application is a console application or a GUI application. For a
console application, the message is written to standard error output. For a
GUI application,
OnShowException is executed.
Errors
If, for a GUI application, OnShowException is not set, no message will be displayed to the user.
The exception message can be at most 255 characters long: It is possible that no memory can be allocated on the heap, so ansistrings are not available, so a shortstring is used to display the message.
