    Differences

    I am learning C++ now and after this I would like to go on to programming for the Windows platform. My question now is if there is any difference between coding using the WIN32 API for different versions of Windows or is there only a difference between coding for a 32 bit and 64 bit processor?

    Not really a big difference between versions of Windows. As long as you stick purely to the Windows API and don't try any 'hack'-ish behaviour then you'll be right. The Windows API is very backward compatible, and MSDN has great documentation so you can find out what the minimum supported client for any given API call is.

    I've compiled 32-bit applications on XP which have then worked reasonably well on 64-bit Windows 7 (there's some compatability layer, I believe?). If you want to compile natively for 64-bit then there are probably some differences, never been bothered to find out the details though.

    Are there any good books for beginners that want to use the WIN32 API that you recommend?

    theForger's Win32 API tutorial is also quite a good guide.

    As an added bonus, it's free!

    Just keep in mind that every release of Windows has additional Win32 functions, structures. It is possible to use Win32 functions that work in Windows 2000 for example, that will not work in Windows NT. I'm using Visual Studio 2005, and there is quite a bit about it in the help file.

    There isn't much difference except that the sizes of types are different. So if you don't rely on this, you should be fine.

    Consider upgrading to 2010 if you can. The Express edition is free.

    For anybody who cares, here is my look into this. The XML files are essentially diffs between Windows versions, and the Access file is what Dependency Walker would be if it was a database, and was ran on every exe and dll in the X86 system/system32 folders since Win98.
