I was wondering how you would get information about the computer, for instance, how much ram is on the computer, how big the hard drive is, how much space on the hard drive is used..etc. any thing that can show info about the computer.. if someone can post an example or some code (in fasm) it would be greatly appreciated..thanks!

1. OS info
Call GetVersionEx and you have everything in OSVERSIONINFO structure

2. Memory info
Call GlobalMemoryStatus and you have everything in MEMORYSTATUS structure

3. Drive info

• GetDriveType what kind of drive is it (eg. hard drive, cd-rom, network drive, etc.)
  
• GetDiskFreeSpace eveyrthing about free space on current drive
  
• GetVolumeInformation another info about drive (eg. serial number, etc.)
  
• GetLogicalDriveStrings returns all present drives' numbers (eg. c:\<null>d:\<null<null>)

how would you go about using that?

SystemParametersInfo and GetSystemMetrics are cool funcs too

pretty easy. define your variable for structure



then you do your



now the osver structure is filled with different data about os version. you could do something like



then you compare major/minor version info to get exact os version. this article here shows you the exact version numbers for different windows: http://www.codeguru.com/Cpp/misc/misc/system/article.php/c8973/

see msdn for exact details on the OSVERSIONINFOEX structure: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/osversioninfo_str.asp

the other APIs listed by Reverend work similarly

i tried the "osver OSVERSIONINFOEX" but it didnt work, is there some othe rway i have to define it other than that?

Have you included kernel32.inc from equates directory? The structure itself is defined there, and the compiler must first process this include file
