看下这个怎么样

程序代码：

;  #define IDOK 1
;  #define IDCANCEL 2
;  #define IDABORT 3
;  #define IDRETRY 4
;  #define IDIGNORE 5
;  #define IDYES 6
;  #define IDNO 7
;  #if(WINVER >= 0x0400)
;  #define IDCLOSE 8
;  #define IDHELP 9

        .386
        .model flat, stdcall
        option casemap:none

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

         .data?
hInstance     dd    ?
hWinMain      dd    ?

        .const
szText        db    'xx', 0
szTextOne     db    'gg', 0
szCaption     db    'oo', 0
szCaptionOne  db    'jj', 0

        .code
_WinMain    proc

        invoke    MessageBox, NULL, offset szText, offset szCaption, MB_YESNO or MB_ICONQUESTION
        cmp       eax, 6
        jne       ok
        invoke    MessageBox, NULL, offset szTextOne, offset szCaptionOne, MB_OK
    ok:    ret

_WinMain endp

start:
        call      _WinMain
        invoke    ExitProcess, NULL
        end       start

貌似可以，那这样为什么不行？
invoke    MessageBox, NULL, offset szText, offset szCaption, MB_YESNO or MB_ICONQUESTION
.if eax==IDYES
  invoke .....
  ....

在eax中有调用这个函数的返回值，就是MB_OK
