x86程序集创建窗口 - 错误A2111:冲突的参数定义和A2008:语法错误 - 如何修复？

Question

我正在关注Iczelion的Win32教程,特别是教程3("简单窗口"),当试图为了实验而"剥离"一些错误处理和不必要的代码时,我在编译时遇到以下错误:

test.asm(38) : error A2111: conflicting parameter definition.

这是一行:

第38行:

WinMain proc hInst:HINSTANCE,hPrevInst:HINSTANCE,CmdShow:DWORD

我的问题是:这行代码有什么问题？

提前致谢.

编辑:

这是整个脚本,其中有违规行注释:

.386 

.model flat, stdcall 
option casemap :none 

WinMain proto :DWORD,:DWORD,:DWORD,:DWORD

include \masm32\include\windows.inc 
include \masm32\include\user32.inc 
include \masm32\include\kernel32.inc 
include \masm32\include\gdi32.inc 
includelib \masm32\lib\user32.lib 
includelib \masm32\lib\kernel32.lib 
includelib \masm32\lib\gdi32.lib

.data 

    ClassName db "Testwin", 0
    AppName db "Testing Window", 0

.data?

    hInstance HINSTANCE ?

.code 
start: 

    push NULL
    call GetModuleHandle
        mov  hInstance,eax
    push SW_SHOWDEFAULT
    push NULL
    push hInstance
    call WinMain
    push eax
        call ExitProcess

WinMain proc hInst:HINSTANCE,hPrevInst:HINSTANCE,CmdShow:DWORD   ; this is the line
; local vars:
LOCAL wc:WNDCLASSEX 
    LOCAL msg:MSG 
    LOCAL hwnd:HWND

; defining the window:
    mov   wc.cbSize,SIZEOF WNDCLASSEX 
    mov   wc.style, CS_HREDRAW or CS_VREDRAW 
    mov   wc.lpfnWndProc, OFFSET WndProc 
    mov   wc.cbClsExtra,NULL 
    mov   wc.cbWndExtra,NULL 
    push  hInst 
    pop   wc.hInstance 
    mov   wc.hbrBackground,COLOR_WINDOW+1 
    mov   wc.lpszMenuName,NULL 
    mov   wc.lpszClassName,OFFSET ClassName 
    invoke LoadIcon,NULL,IDI_APPLICATION 
    mov   wc.hIcon,eax 
    mov   wc.hIconSm,eax 
    invoke LoadCursor,NULL,IDC_ARROW 
    mov   wc.hCursor,eax 
    invoke RegisterClassEx, addr wc 
;create the window
    invoke CreateWindowEx,NULL,ADDR ClassName,ADDR AppName,\ 
           WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,\ 
           CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,\ 
           hInst,NULL
    invoke ShowWindow,hwnd,CmdShow
WinMain endp

WndProc proc hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM   
    cmp uMsg, WM_DESTROY
    jne _next
    invoke PostQuitMessage, NULL
_next:

WndProc endp      
end start    

希望这可以帮助.

这三条错误消息准确地解释了您做错了什么.

test.asm(38) : error A2111: conflicting parameter definition.

再看看你的原型:

WinMain proc hInst:HINSTANCE,hPrevInst:HINSTANCE,CmdShow:DWORD

WinMain与先前声明冲突的参数.如果查看前面的声明,您会看到参数列表不同.

下一个错误:

test.asm(69) : error A2008: syntax error: WndProc

我们来看看那一行:

WndProc WndProc proc hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM

语法错误意味着您违反了语法.在这种情况下,这是因为汇编程序无法弄清楚如何处理第二个WndProc; 重复WndProc在这里不合法.

第三个错误:

test.asm(75) : fatal error A1010: unmatched block nesting: WndProc

由于该WndProc过程从未正确启动,因此您尝试结束该过程无效.

TL; DR:读取错误消息.他们会解释你做错了什么.
