Porting 32 bit applications to 64 bit in Visual Studio 2005

[r***@gmail.com]

Hi all,
I am trying to convert my 32 bit application in C++ to a 64 bit
compatible platform on Visual Studio 2005.

I was wondering if you could guide me in this matter. I know that we
have to change variables etc appropritely and compile it in x64 mode.

If I am working on a 32-bit machine how do i test and basically run
the 64bit version on my machine? IS it possible to do so? ( running
the 64 bit converted code on a 32bit machine...)

Im using macros to make it compatible in x64.

Any guidance is really appreciated .... Thank you all for taking the
time to help me!

You don't. You can build for x64 on a 32-bit machine, but you can't run it.
You'll need a 64-bit machine to test your code. Even if you're running
32-bit OS, if your processor is x64 capable, you may be able to create a
64-bit virtual machine on it using VMWare workstation (I'm pretty sure that
you cannot do it using Microsoft Virtual PC).
