As I mentioned I was reporting on things 7 years old, with failing
memory quite common to my age. <br>
<br>
And I am not going to spend the time searching for it to prove you
right or wrong. Again, from memory, Intel was changing the design of
the memory manager which was going to mean that a better definition of
the null pointer would be ffffffffff... What happened with that, I do
not know or care.<br>
<br>
As for the rest, please pretend you are hearing the stereotypical
Indian voice.<br>
<br>
"Oh my golly gosh, thank you for clarifying that sir. I must have
spent months trying a billion solutions before I must have accidentally
found the X2."<br>
<br>
Did it not occur to you, that it works because I knew what I was
doing.... :-) And before you retort, I do not modify the vcl for any
reason as it could lead to problems when using bpls on a clients
machine where they already exist from some other application.<br>

was no change in the “Windows standard”. It’s a simple error

point (subsequently

needn’t have waded through all the replies to find that the

was a
great deal of pointless and diverting/misleading speculation as to
other possible

apparent from an inspection of the VCL source.<o:p></o:p></span></p>

- Your “multiple by 2” solution worked because it
transformed a stored value of “-1” into “-2”, which then avoided the
collision
between that value (-1) and the Windows “error” code and thus avoided
the
problem caused by the overly-helpful and incorrectly implemented error
handling
code in the VCL.<o:p></o:p></span></p>
