I need get the size of a string.
I'm using now this:

Code:

win_size   equ $-WinDir

        invoke GetWindowsDirectory,\
               WinDir,\
               256d

but i don't know if is correct.
Exits other way of get the size of a string?

you could do it like this,

Code:

mydir rb 0xFF
mydirsize dd 0

invoke GetWindowsDirectory,mydir,0xFF
mov  [mydirsize],eax

the above would make mydirsize contained the count of bytes copied into mydir.

Win95 & NT had 255 (100h-"\n"-character), but recent versions of NT have 260 <= I don't know what is it good for Razz

Maybe they lend 5 bytes from the name of the file or maybe they strip off C:/ drive identification.
