一下汇编创建窗口为什么不成功

Assembly code

start:main proc;create main window    local hWnd:dword    local pWndClass:WNDCLASSEX,pMsg:MSG        invoke RtlZeroMemory,addr pWndClass,sizeof WNDCLASSEX    invoke GetModuleHandle,m_null    mov hInst,eax    mov pWndClass.hInstance,eax    invoke LoadCursor,0,IDC_ARROW    mov    pWndClass.hCursor,eax    mov pWndClass.cbSize,sizeof WNDCLASSEX    mov    pWndClass.style,CS_HREDRAW or CS_VREDRAW    mov    pWndClass.lpfnWndProc,offset WndProc    mov pWndClass.lpszClassName,offset msz_WndClass    mov    pWndClass.hbrBackground,COLOR_WINDOW + 1    invoke RegisterClassEx,addr pWndClass    invoke CreateWindowEx,WS_EX_CLIENTEDGE,offset msz_WndClass,offset msz_WndTitle,\        WS_OVERLAPPEDWINDOW,100,100,600,400,m_null,m_null,hInst,m_null    cmp eax,0 ;每次执行CreateWindowEx的eax都是0    jz @exitproc    mov hWnd,eax    invoke ShowWindow,hWnd,SW_SHOWNORMAL    invoke UpdateWindow,hWnd@msgloop:    invoke GetMessage,addr pMsg,m_null,m_null,m_null    cmp eax,0    jz @exitproc    invoke TranslateMessage,addr pMsg    invoke DispatchMessage,addr pMsg@exitproc:    invoke ExitProcess,m_nullmain endpend start

[解决办法]
没有头文件吧.
[解决办法]
@msgloop:
invoke GetMessage,addr pMsg,m_null,m_null,m_null
cmp eax,0
jz @exitproc
invoke TranslateMessage,addr pMsg
invoke DispatchMessage,addr pMsg
@exitproc:
没有头文件
你这个没有在进行消息循环，把完整的文件发上来看一下
[解决办法]
试一下吧

[code=Assembl]start:
main proc;create main window
local hWnd:dword
local pWndClass:WNDCLASSEX,pMsg:MSG

invoke RtlZeroMemory,addr pWndClass,sizeof WNDCLASSEX
invoke GetModuleHandle,m_null
mov hInst,eax
mov pWndClass.hInstance,eax
invoke LoadCursor,0,IDC_ARROW
mov pWndClass.hCursor,eax
mov pWndClass.cbSize,sizeof WNDCLASSEX
mov pWndClass.style,CS_HREDRAW or CS_VREDRAW
mov pWndClass.lpfnWndProc,offset WndProc
mov pWndClass.lpszClassName,offset msz_WndClass
mov pWndClass.hbrBackground,COLOR_WINDOW + 1
invoke RegisterClassEx,addr pWndClass
invoke CreateWindowEx,WS_EX_CLIENTEDGE,offset msz_WndClass,offset msz_WndTitle,\
WS_OVERLAPPEDWINDOW,100,100,600,400,m_null,m_null,hInst,m_null
cmp eax,0
jz @exitproc ;楼主不妨在此句后invoke MessageBox,如果能弹出来说明不是0
mov hWnd,eax
invoke ShowWindow,hWnd,SW_SHOWNORMAL
invoke UpdateWindow,hWnd
@msgloop:
invoke GetMessage,addr pMsg,m_null,m_null,m_null
cmp eax,0
jz @exitproc
invoke TranslateMessage,addr pMsg
invoke DispatchMessage,addr pMsg
jmp@msgloop ;关键是这里，消息循环 应该是漏写了吧
@exitproc:
invoke ExitProcess,m_null
main endp
endstart[/code]
[解决办法]
好像没有包含头文件哦
