ASNI 与 UNICODE 的选择!
我们来看 Hello Word!到例子 !~~
程序代码：
.386
.Model Flat, StdCall
Option Casemap :None

Include        Windows.inc
Include        User32.inc
Include        Kernel32.inc

Include        /MASMPlus/macros/Strings.mac

IncludeLib    User32.lib
IncludeLib    Kernel32.lib

.Code

Start Proc

    invoke    MessageBoxW,NULL,$CTW0("AAAAW"),0,0    
    ret
    
Start EndP

End Start

先从UNICODE函数说起 !~

以下是OD跟踪 MessageBoxW 过程

程序代码：
MessageBoxW:

00401000 >  6A 00           push    0                    ; uType
00401002    6A 00           push    0                    ; lpCaption
00401004    68 08204000     push    00402008                ; lpText  UNICODE "AAAAW"
00401009    6A 00           push    0                    ; hWnd
0040100B    E8 02000000     call    <jmp.&user32.MessageBoxW>        ; 这里CALL进去看        
00401010    C3              retn

00401011    CC              int3
00401012  - FF25 00204000   jmp     dword ptr [<&user32.MessageBoxW>>; user32.MessageBoxW ; JMP过去

就是填充局部变量       由以上内容我们得知
局部变量共  4ch(76字节)分布情况如下

dword ptr [ebp-4C] == 28h        4
dword ptr [ebp-48] == hWnd        4
dword ptr [ebp-44] == 0            4
dword ptr [ebp-40] == lpText        4
dword ptr [ebp-3C] == lpCaption        4
dword ptr [ebp-38] == uType        4
word ptr  [ebp-20] == wLanguageId    2
dword ptr [ebp-8]  == dwMilliseconds    4

MessageBoxW调用顺序是 

MessageBoxW -> MessageBoxExW -> MessageBoxTimeoutW 

通过以上分析我们可以得知 直接调用 MessageBoxTimeoutW 可以省略很多无用到步骤 
此函数由 USER32导出 

MessageBoxTimeoutW 声明如下

MessageBoxTimeoutW PROTO hWnd:DWORD,lpText:DWORD,lpCaption:DWORD,uType:DWORD,wLanguageId:WORD,dwMilliseconds:DWORD

wLanguageId 是0
dwMilliseconds 是 -1

调用如下:

invoke    MessageBoxTimeoutW,NULL,$CTW0("AAAAW"),0,0,0,-1

好了我们继续看 MessageBoxA函数

程序代码：
.386
.Model Flat, StdCall
Option Casemap :None

Include        Windows.inc
Include        User32.inc
Include        Kernel32.inc

Include        /MASMPlus/macros/Strings.mac

IncludeLib    User32.lib
IncludeLib    Kernel32.lib

.Code

Start Proc

    invoke    MessageBoxA,NULL,$CTA0("AAAAW"),0,0
    ret
    
Start EndP

End Start

OD跟踪如下

程序代码：
00401000 >  6A 00           push    0
00401002    6A 00           push    0
00401004    68 08204000     push    00402008                ; ASCII "AAAAW"
00401009    6A 00           push    0
0040100B    E8 02000000     call    <jmp.&user32.MessageBoxA>        ; call进去看
00401010    C3              retn

00401011    CC              int3
00401012  - FF25 00204000   jmp     dword ptr [<&user32.MessageBoxA>>; user32.MessageBoxA 跳到MessageBoxA函数

; 下面到不解释了 自己看吧 到这里已经很明确了
 MessageBoxA 实际就是将 ANSI转换成 UNICODE然后调用 MessageBoxTimeoutW
 具体编程过程中应该使用ANSI 还是 UNICODE 大家也应该明确了 呵呵!~~

啊，不错。
做教学很好。实用效果不大。因为这个并不常用。

如果追求实战速度，最好能把Kernel32中的包装全部去掉，对应到Ntdll.dll的函数中。GDI、GDI+中的函数再深挖一下。

搞出个“Direct Win32Api SDK”

哈哈  貌似我写跑题了 哈哈!~

实质在于 推荐使用 Unicode



Direct Win32Api SDK 很好很强大 哈哈

程序代码：
.386 
.Model Flat,StdCall 
Option Casemap :None 
 
Include        Windows.inc 
Include        User32.inc 
Include        Kernel32.inc 
 
Include        /MASMPlus/Macros/Strings.Mac 
 
IncludeLib    User32.lib 
IncludeLib    Kernel32.lib 
 
MessageBoxTimeoutW PROTO hWnd:DWORD,lpText:DWORD,lpCaption:DWORD,uType:DWORD,wLanguageId:WORD,dwMilliseconds:DWORD 
 
.Data? 
usText        db    128 dup (?) 
usCaption    db    128 dup (?) 
 
.Code 
 
Ascii2Unicode     Proc _lpwszReturnBuf:DWORD,_lpszSourceBuf:DWORD 
     
    pushad 
    invoke    lstrlen,_lpszSourceBuf 
    inc        eax 
    invoke    MultiByteToWideChar,CP_ACP,0,_lpszSourceBuf,-1,_lpwszReturnBuf,eax 
    popad 
    ret 
     
Ascii2Unicode    EndP 
 
Start    Proc 
 
    invoke    Ascii2Unicode,offset usText,CTEXT("这里是Text!") 
    invoke    Ascii2Unicode,offset usCaption,CTEXT("这里是Caption!") 
    invoke    MessageBoxTimeoutW,0,offset usText,offset usCaption,1,0,-1 
    invoke    Ascii2Unicode,offset usCaption,CTEXT("提示") 
     
    .if eax == IDOK 
        invoke    Ascii2Unicode,offset usText,CTEXT("您点了确定按钮!") 
        invoke    MessageBoxTimeoutW,0,offset usText,offset usCaption,0,0,-1 
         
    .elseif    eax == IDCANCEL 
        invoke    Ascii2Unicode,offset usText,CTEXT("您点了取消按钮!") 
        invoke    MessageBoxTimeoutW,0,offset usText,offset usCaption,0,0,-1 
         
    .endif 
     
    ret 
     
Start EndP 
 
End Start

动态转换或者 自己写宏!~

以下是引用sll0807在2009-10-18 10:52:31的发言：

.386
.Model Flat,StdCall
Option Casemap :None
 
Include        Windows.inc
Include        User32.inc
Include        Kernel32.inc
 
Include        /MASMPlus/Macros/Strings.Mac
 
IncludeLib    Us ...

动态转换太占地方了~
