OS Exceptions (Tools|Debugger Options)
The scroll box on the top lists exceptions, and in the fields on the bottom
you specify how the exception will be handled. To change the options
for handling exceptions, highlight the exception you want to change
and adjust the Handled By and On Resume options.
Handled By specifies whether the exception will be handled by the
Debugger or by your program. If you have added exception handling
to your project, select User Program.
On Resume specifies whether Delphi will continue
to handle the exception, or whether the project will run unhandled.
Add button bringsup the Add Exception Range dialog box.
This allows you to add user-defined exceptions to be handled by the debugger.
Remove button removes a selected item from the list. Select
the item you want to remove and click Remove. This allows you to
remove a user-defined exception from the list. Currently, you can
only remove exceptions that you have added. This button will be gray
anytime a default exception is selected. You can only remove
user-defined exceptions.
Integrated debugging check box sets the Integrated Debugger
to active. This option is on by default.
