From a long time i have problem with this function. I know that in windows files are case insensitive, but 'cd' command wotks fine.
Code:
section '.code' code readable executable
push buff
push 256
call [GetCurrentDirectoryA]
push buff
call [puts]
push dir
call [SetCurrentDirectoryA]
push buff
push 256
call [GetCurrentDirectoryA]
push buff
call [puts]
add esp, 8
ret
section '.data' data readable writeable
buff rb 256
dir db '../DeSkTop',0    


and output is:
Code:
C:\Documents and Settings\Administrator\Desktop
C:\Documents and Settings\Administrator\DeSkTop    

If i do a cd command 'cd DesKToP', getcurrentdirectory will output real name, 'Desktop'. Why its that? How can i fix it?

for one, you are using 'puts'. You shouldn't use that. Second, windows is probably, (after it verifies the path) just spitting out the string you gave it. I don't think it would bother to look up the "real" name if the name you gave it works just fine. Think of it this way: If files are case-insensitive, and you were the windows designer, do you think that you would take the file path, verify it, then lookup the lower-case file name, then use that? NOOO You would just give back in the case that the user gave it. Should work just fine, if you want to check if the user has inputted a file name with any capitals, just cycle through the bytes checking for ones below 0x61. That should verify that the string has all lowercase letters

You could try using GetFullPathName. Just a stab in the dark here, I haven't tried it.

There a few file related API's. I think you just need to try them one by one to see which one gives you what you want.

FindFirstFile?

FindFirstFile will give you the "real name" of the folder. GetLongPathName() seems to work as well, but I'm not sure whether it'll fail on some windows versions when using a "long filename" as input...
