我哪里写错了呀？？

push ebp
mov ebp,esp
sub esp, 80h

mov byte ptr[ebp-15h],61h//a.dll
mov byte ptr[ebp-14h],2eh//.
mov byte ptr[ebp-13h],64h//d
mov byte ptr[ebp-12h],6ch//l
mov byte ptr[ebp-11h],6ch//l
mov byte ptr[ebp-10h],0h//0x00
lea esi,[ebp-15h]
mov byte ptr[ebp-02h],62h//b
mov byte ptr[ebp-01h],0h//0x00
lea edi,[ebp-02h]

push ebx
push esi //标题
mov eax,7C801D7Bh
call eax

mov ebx,eax

push ebx
push edi //内容

mov eax,7c80ae40h
call eax

mov ebx,eax
call ebx

7C801D7Bh LoadLibrary
