高分求解：如何调试VB编写的ActiveX DLL程序，谢谢！

Cooly 大哥，有关调试的问题能给个建议吗？

更令我气愤的是，函数明明在标准exe文件里运行正常，但是在Activex DLL里就不行！
Faint!

我也没什么好办法。:(
我一般是创建一个VB的虚拟环境，测试完毕以后再用ASP调用。

Public Function GetMACAddress(sIP As String)
    Dim sRtn As String
    Dim myNcb As NCB
    Dim bRet As Byte
    sRtn = ""

    myNcb.ncb_command = NCBRESET
    bRet = Netbios(myNcb)
    myNcb.ncb_command = NCBASTAT
    myNcb.ncb_lana_num = 0
    myNcb.ncb_callname = sIP    Dim myASTAT As ASTAT, tempASTAT As ASTAT
    Dim pASTAT As Long
    myNcb.ncb_length = Len(myASTAT)
    Debug.Print Err.LastDllError
    pASTAT = HeapAlloc(GetProcessHeap(), HEAP_GENERATE_EXCEPTIONS Or HEAP_ZERO_MEMORY, myNcb.ncb_length)
    If pASTAT = 0 Then
        Debug.Print "memory allcoation failed!"
        Exit Function
    End If    myNcb.ncb_buffer = pASTAT
    bRet = Netbios(myNcb)
   Debug.Print Err.LastDllError
    CopyMemory myASTAT, myNcb.ncb_buffer, Len(myASTAT)

    Dim sTemp As String
    Dim i As Long
    For i = 0 To 5
        sTemp = Hex(myASTAT.adapt.adapter_address(i))
        Debug.Print sTemp
        sRtn = sRtn & IIf(Len(sTemp) < 2, "0" & sTemp, sTemp)
    Next
    HeapFree GetProcessHeap(), 0, pASTAT
    GetMACAddress = sRtn
End Function

刚才我试了一下，用VB建了一个exe,调用这个dll，没有问题，但是在asp下还是不行！7456!
似乎asp还是调用了那个旧的文件，对于我这个改正的文件根本没反应！可是我刚启动完服务器呀，旧文件也早被我删掉了！

版本的问题，重新编译一次，并且要保证旧版本已经被替换掉，并且重新注册DLL一次

fuck Microsoft!
我改了一下版本，重新编译，然后在注册表里删了个干净，然后重新启动机器，
这回报告asp出错，等我注册完以后，得到的mac地址还是一堆0，
用VB调用这个dll，没有问题呀！

刚才我又增加了一个函数
function xxx() as string
xxx="lllll"
end function
重新来了一遍，发现asp可以调用这个函数，说明asp已经接受了最新版的文件，现在看来问题就在GetMACAddress()函数本身了。

这段程序是我从一个网站上抄下来的，难道不能运行在ActiveX dll方式下？

我又改了一下，减少了api函数的调用
Public Function GetMACAddress(sIP As String) As String
    Dim sRtn As String
    Dim myNcb As NCB
    Dim bRet As Byte
    Dim sBuf() As Byte

    sRtn = ""
    myNcb.ncb_command = NCBRESET
    bRet = Netbios(myNcb)
    myNcb.ncb_command = NCBASTAT
    myNcb.ncb_lana_num = 0
    myNcb.ncb_callname = sIP    Dim myASTAT As ASTAT, tempASTAT As ASTAT
    myNcb.ncb_length = Len(myASTAT)
    ReDim sBuf(myNcb.ncb_length)    myNcb.ncb_buffer = VarPtr(sBuf(0))
    Debug.Print myNcb.ncb_buffer
    bRet = Netbios(myNcb)
    Debug.Print Err.LastDllError
    CopyMemory myASTAT, myNcb.ncb_buffer, Len(myASTAT)

    Dim sTemp As String
    Dim i As Long
    For i = 0 To 5
        sTemp = Hex(myASTAT.adapt.adapter_address(i))
        Debug.Print sTemp
        sRtn = sRtn & IIf(Len(sTemp) < 2, "0" & sTemp, sTemp)
    Next
    GetMACAddress = sRtn
End Function
同时又改了很多编译选项（无优化... ...）反正无效！
不知是Netbios()还是CopyMemory引起错误，或者是asp与VB对ActiveX DLL采用了不同的调用方式？

下面是我写的一个DLL,编译以后可以正常使用.
下附ASP代码.另外,一定要注意,调用dll的asp页面的匿名访问账号要用有管理员权限的账号,具体如何设置不用我说了吧.   Option Explicit   Private Const NCBASTAT = &H33

Cooly大哥:
你的程序我明天试一下（不过，好像只增加了一些判定、整理的东西呀？）请再看一下这个，反正我是执行不了。

为什么我如此倒霉！
================

我倒！我怎么这么弱智？！！！！！！
真是恨不得跳楼死了算了！
我分析了半天程序，原来我的asp里面
response.write(xxx.GetMACAddress("192.168.0.71"))
被我写成了
response.write(xxx.GetMACAddress("10.128.0.71"))
要不是Cooly大哥的程序返回来一句
Can not get the MAC Address from IP Address
我还傻呢！
哭ing.......

调试易
