#include “windows.h”
#include “tchar.h”
WCHAR a[]=L”123″;
int WINAPI MyFonc(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
WCHAR b[]=L”456″;
HMODULE hmodule=LoadLibrary(L”user32.dll”);
FARPROC addr=GetProcAddress(hmodule,”MessageBoxW”);
__asm
{
  push 0
  mov eax,offset a//全局用offset
  push eax
  lea eax,b//局部用lea
  push eax
  push 0
  call addr
