我正在尝试使用CreateWindowEx
API 在 x86 程序集中创建一个带有 masm32 的窗口。我已经让我的代码没有编译时错误或任何类似的错误——它编译得很好。然而,当我运行 exe 时,什么也没有发生。我没有看到任何明显的错误,实际上我已经从 Iczelion 的 Win32 教程(第 3 部分 - 一个简单的窗口)中复制了代码。它有什么问题?
这是我的代码:
.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 ?
CommandLine LPSTR ?
.code
start:
push NULL
call GetModuleHandle
mov hInstance,eax
call GetCommandLine
mov CommandLine, eax
push SW_SHOWDEFAULT
push CommandLine
push NULL
push hInstance
call WinMain
push eax
call ExitProcess
WinMain proc hInst:HINSTANCE,hPrevInst:HINSTANCE, CmdLine:LPSTR,CmdShow:DWORD
; 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,SW_SHOWNORMAL
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
我哪里出错了?我怀疑它与CreateWindowEx
,考虑到它需要 12 个参数,其中大部分我不明白。
提前致谢。
