能告诉我这个函数中对传入的这几个参数作了什么样的计算吗?(200分)

jafy · 2003-10-24

请问高手,我有一个以前的16位的DLL现在要在DELPHI写的程序中调用: Declare Function func1 Lib "AQN.DLL" Alias "Equation" (p1,p2,p3,p4) As Integer 在程序中调用得到:func1(345,140.794871794872,1,0)=20.2919800498571 我使用反汇编工具把AQN.DLL反汇编后得到以下汇编代码,但因为实在看不懂汇编,请问我这个函数中对传入的这几个参数作了什么样的计算?写成PASCAL语句该如何写,十分感谢!!!(以下是反汇编后该函数的片断,不知道是否全了?) mov ax, SEG ADDR of Segment 0004  push bp  mov bp, sp  push ds  mov ds, ax  mov ax,

难啊，逆向工程

app2001 · 2003-10-24

为什么要反汇编出来，还不如想想怎么在程序中调用十六位的DLL好一些，你认为呢？ 如何调用16位Dll 1.要创建一个Thunk Script 脚本 2。要创建一个32bit DLL 3.要利用32bit DLL来调用16bit DLL 然后用VC带的Thunk.exe来编译那个ThunkScript 用MASM来编译产生的汇编代码 我只找到这么些资料

同上。

利用 Windows95 Direct Thunking 机制调用 16 Bit DLL 的范例程序。 http://www.csdn.net/dev/delphi/Samples/D2THUNK.ZIP

我早就有D2THUNK.ZIP了，只不过这个程序好像在WINME下不能执行，一执行就出错！

能告诉我这个函数中对传入的这几个参数作了什么样的计算吗?(200分)
