Question

我是msdn库和masm的新手。

在调用NetUserAdd之后，我尝试调用NetLocalGroupAddMembers，但它需要类型LPCWSTR作为组名。我认为这就是为什么我创建的帐户不可见，并且在调用NetLocalGroupAddMembers后仍然没有出现。

（我导入了很多文件，因为我的代码不完整，我知道我要添加的内容。）

这是我的代码：

.386
.model flat,stdcall 
option casemap:none 
include \masm32\include\windows.inc 
include \masm32\include\user32.inc 
INCLUDE \masm32\include\msvcrt.inc
include \masm32\include\kernel32.inc 
includelib \masm32\lib\user32.lib
includelib \masm32\lib\kernel32.lib
INCLUDELIB \masm32\lib\msvcrt.lib
include \masm32\include\netapi32.inc
INCLUDELIB \masm32\lib\netapi32.lib


.data

lmi3 LOCALGROUP_MEMBERS_INFO_3 <>

domain byte "WIN-XXX\NAME",0

;conversion of domain to unicode
domainName BYTE 500 DUP(?)

; argument for NetUserAdd
error byte 50 dup(?)

; user name and password for new user
userPassword byte "NAME",0
userName byte "PWD",0

; will contain conversion of userPassword and userName to unicode
user byte 500 dup(?)
pwd byte 500 dup(?)

;structure declaration fo NetAddUser
account USER_INFO_1 <>

groupName BYTE "Users",0

; where I would place conversion of groupName
uniGroupName byte 200 DUP(?)

.code

main PROC

    ; convert to lpwstr (unicode)
    invoke MultiByteToWideChar, CP_ACP, NULL, addr userName, -1, addr user, 500
    invoke MultiByteToWideChar, CP_ACP, NULL, addr userPassword, -1, addr pwd, 500

    mov account.usri1_name, offset user
    mov account.usri1_password, offset pwd
    ; user access has to be User_Priv_User to call NetAddUser
    mov account.usri1_priv, USER_PRIV_USER
    mov account.usri1_home_dir, NULL
    mov account.usri1_comment, NULL
    mov account.usri1_flags, UF_SCRIPT 
    mov account.usri1_script_path, NULL

    ; 1 indicates user_info_1
    invoke NetUserAdd, NULL, 1, addr account, offset error

    ; conversion to lpwstr
    invoke MultiByteToWideChar, CP_ACP, NULL, addr domain, -1, addr domainName, 500

    mov lmi3.lgrmi3_domainandname, offset domainAndName

    ; uniGroupName needs to be in LPCWSTR
    invoke NetLocalGroupAddMembers,NULL,addr uniGroupName,3, offset lmi3,1

    invoke ExitProcess,0 

; end of procedure
main ENDP


; end of program
END main

您可以将群组名称字符串声明为DW 'U','s','e','r','s',0。或者，如果您希望在运行时进行转换，则可以使用crt_mbstowcs中的msvcrt函数。

这是一个测试两种方法的小例子程序：

.686p
.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc
include \masm32\include\kernel32.inc
include \masm32\include\user32.inc
include \masm32\include\msvcrt.inc

includelib \masm32\lib\kernel32.lib
includelib \masm32\lib\user32.lib
includelib \masm32\lib\msvcrt.lib

.data

; %s for ASCII, %S for wide strings
format db "original: %s, converted: %S",13,10,0

; An ASCII string that we'll convert at runtime
original db "Foobar",0
converted dw 32 dup(0)

; A statically created wide string    
testws dw 'T','e','s','t',13,10,0

.code

main PROC

; Print our statically created wide string
invoke crt_wprintf, ADDR testws

; Converts the characters in 'original' into wide characters and stores them
; in 'converted'.
invoke lstrlen,ADDR original
invoke crt_mbstowcs, ADDR converted, ADDR original, eax

; Print both the original and converted string, then exit the program.
invoke crt_printf, ADDR format, ADDR original, ADDR converted
invoke ExitProcess, 0

main ENDP

END main
