I use Prop:LastChanceHook to hook the exception so before the user ever sees the Exception Message I can call ExInfo.LogException() to write the Exception Log file. That way I do not reply on the user to click “Log Info”. I also show a message more suited to End Users.
I attached small test project that displays this window to allow with Last Chance hooked and an option to use PROP:FatalErrorHook and cause an Index error:
Checking CHECK('Hook PROP:FatalErrorHook') my code gets the call and shows a simple message. The RTL passes no call stack and not much of details needed.
One idea was to have that Fatal message GPF with a Peek(0) which will throw an Exception so I get a call stack like below:
This adds FatalErrorTaker() to the call stack, but at least the original problem shows that was at line 88.
I don’t like using PEEK(0) as it shows the very common “Access Violation”. I took a quick try at causing an exception named “Array Bounds Exceeded”, but the below code just hung for a while then closed the program.
Does anyone know how to cause a specific exception?
RaiseException(UNSIGNED dwExceptionCode, UNSIGNED dwExceptionFlags, UNSIGNED nNumberOfArguments, LONG Address_lpArguments ),RAW,PASCAL,DLL(1)
EXCEPTION_ARRAY_BOUNDS_EXCEEDED EQUATE(0C000008Ch)
EXCEPTION_NONCONTINUABLE EQUATE(1) !Noncontinuable exception
RaiseException(EXCEPTION_ARRAY_BOUNDS_EXCEEDED, EXCEPTION_NONCONTINUABLE, 0,0)
