How can I do this?

data db dup(?)
push MB_ICONERROR
push DWORD PTR DS: data+WNDCLASS.lpszClassName ; (DON'T WORK)... In C is ((WNDCLASS *)data)->lpszClassName
push text
push 0
call [MessageBox]

push DWORD PTR DS: data+36 ; is not easy...

From Argentina
Thanks

wcdata WNDCLASS
stdcall MessageBox,0,text,[wcdata.lpszClassName],MB_ICONERROR

I know it.. But it is a permanent memory... I am using a temporary memory for all uses..

In C, I used:
UCHAR data[512]; // Temp Memory 512 Bytes
//...
MessageBox(NULL,"Hello",((WNDCLASS *)data)->lpszClassName,MB_ICONERROR);
// ... The same
MessageBox(NULL,"Hello",((DWORD *)(data+36))[0],MB_ICONERROR);
// ...

How?
