Code Select Expand

include \masm32\include\masm32rt.inc

.data?
buffer db MAX_PATH dup(?)

.code
start:
invoke GetEnvironmentVariable, chr$("windir"), offset buffer, sizeof buffer
MsgBox 0, offset buffer, "%Windir%", MB_OK
exit

end start


[starzboy]

that means i will have to remove the "%" and make it "windir" before using GetEnvironmentVariable ?
i will have to cut strings in 2 parts, is there any other way out ?

Hello,
There is also this form,

      ;include \masm32\include\advapi32.inc + lib
      ;include \masm32\include\shell32.inc + lib
      ; define in ShlObj.h
      SHGFP_TYPE_CURRENT equ 0
      CSIDL_COMMON_DOCUMENTS equ 02eh

      ;------- data ----
      Htoken dd 0
      Chemin db MAX_PATH + 1 dup (0)
      titre db "title",0
      ;----------- code -----------------------
      
      invoke OpenProcessToken,hInstance,TOKEN_READ,addr Htoken
      invoke SHGetFolderPath,NULL,CSIDL_SENDTO,Htoken,SHGFP_TYPE_CURRENT,addr Chemin      

The CSIDL_... are differents constants who give differents paths.
In this piece of code that you have to modify in your source, "chemin" is the variable where the returned path is written

re,
the ""%windir%/cyz.bat" make a ref to batch file.
In a batch, you can use it directly.

SET BATCH=%windir%\cyz.bat

Try ExpandEnvironmentStrings

Try ExpandEnvironmentStrings

That (and ExpandEnvironmentStringsForUser) are a good find  :thumbu

Never heard of those before.
