Hello,
But the Abort() routine is not working currently since when the exception is
thrown and not excepted/catched it quits the function! And this call is in
InternalAbort() so it could be called by other component code as well (not
just applications' direct call to Abort() )! And why would anybody care when
the "Operation already in progress" exception is thrown in Abort()?
Regards,
SZ
