/* NOTE : The first call to this may cause a first-chance exception. Excerpt from MSDN January 2000.
Note The first time a property page is created from its corresponding dialog resource,
it may cause a first-chance exception. This is a result of the property page changing
the style of the dialog resource to the required style prior to creating the page. Because
resources are generally read-only, this causes an exception. The exception is handled by
the system, and a copy of the modified resource is made automatically by the system. The
first-chance exception can thus be ignored.
Since this exception must be handled by the operating system, do not wrap calls to
CPropertySheet::DoModal with a C++ try/catch block in which the catch handles all exceptions,
for example, catch (...). This will handle the exception intended for the operating system,
causing unpredictable behavior. Using C++ exception handling with specific exception types
or using structured exception handling where the Access Violation exception is passed through
to the operating system is safe, however.
