I have a 32 bit version of the 2008 visual studio. I am a little mixed up with the different places to switch between 64 bit and 32 bit.
I notice that on the top I have a Debug or Release and a platform choice between Win32 and x64. If i choose x64, does it mean that if I used a Custom Build Rule for one of my files , it would also need to use a 64 bit version of a rule file?
Also, when you build for a x64 platform using 32 bit Visual Studio, what actually happens? The libraries linked in etc - are they all magically picked up if they are 64 bit and the 32 bit version are ignored.
What would be different if i used a 64 bit version of Visual Studio and the platform chosen was x64?
