    overflow checking

    Is there a way to stop overflow checking at runtime in VB.NET? I have one
    math calculation that must behave like another system, it could generate a
    number > 2 billion (<4) which then needs to go into a signed 32 bit integer.
    I don't want to disable it for the entire program though, just at one spot.

    Thanks,
    Sean

      Sean,

      Go to Project Properties, Configuration Properties, Optimizations and check
      the box that says "Remove Integer Overflow Checks"

      HTH,

              But that removes it from the entire project does it not?

                      Sean,

                      Yes, sorry about that. I forgot you didn't want to remove it from the
                      entire project. In your case, I'm not sure it can be done. You might look
                      at removeintchecks compiler option, although I still don't think its going
                      to help you solve what you want to do. I'm pretty sure that does the same
                      thing as going in and checking that box, but I haven't really looked into
                      it.

                      HTH,
