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>)

pretty easy. define your variable for structure

Code:

osver OSVERSIONINFOEX

then you do your

Code:

invoke    GetVersionEx,osver

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

Code:

cmp    dword [osver.dwPlatformId],VER_PLATFORM_WIN32_NT
je       winnt_platform
;if jump youre on nt platform, if no jump youre on win 9x/me platform

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

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