Hi:
According to the help file, "The __finally keyword specifies actions that
should be taken regardless of how the flow within the preceding __try
exits.". But in the example below the __finally block will not execute if we
get to return statement. Any ideas? Could this be a builder bug?
if the return is within the first try and not the nested one it works fine.
I have tried this in BCB5 Ent. and BCB6 Ent.
try
{
   try
   {
      /* Do something */
      if (/* some condition */)
         return;
      /* Do something */
   }
   catch (...)
   {
      /* Do something */
   }
}
__finally
{
    /* Do something */
}

Instead of testing for true and returning , why not test for false and
execute  /* Do something */ then let the function return itself.

instead of this

      if (/* some condition */)
         return;
      /* Do something */

try this
      if (/* !some condition */)
      /* Do something */

I knew the workaround. I was just wondering if this is by design or a
compiler bug.

Sam S. Firouz,

You would do better asking C++ language questions in the newsgroup 
section set aside for them. It's not hard to find as it's called 
LANGUAGE.CPP

Aside from the comment about .cpp.language, you might read your own post
a little more closely for a possible solution.  The help file states
'__try' and your code has 'try'.

'course, this has likely been answered in the 2 intervening weeks in the
other newsgroup and I have *no* idea the difference 'tween the two types
of 'try' statements but...
