用了sczyq(我又...........) 的紧用和启动网卡的程序，并且安装了DDK，包含文件都弄好了，可是报错是怎么回事。我是初级菜鸟，请大家指教

请指教，谢谢。。。

[gycxy]

我觉得是你包含的PHKEY定义有多个,看看你的包含文件或包含的顺序

[sczyq]

同意gycxy(静水)，事实正是由此而起。


[C++ Error] cfgmgr32.h(2416): E2015 Ambiguity between 'PHKEY' and 'Windows::PHKEY'

这是说明cfgmgr32.h 里第2416行 PHKEY 的数据类型的名称与Windows类的PHKEY重复了,你得找到cfgmgr32.h里出现PHKEY的地方(应该是6处，行号就是括号里的),改成 Windows::PHKEY

如：
CM_Open_Class_KeyA(
IN LPGUID ClassGuid, OPTIONAL
IN LPCSTR pszClassName, OPTIONAL
IN REGSAM samDesired,
IN REGDISPOSITION Disposition,
OUT Windows::PHKEY phkClass, // 这是第2416行，加上Windows::
IN ULONG ulFlags
);


以下错误是因为上面的错误引起的.
[C++ Error] Unit1.cpp(37): E2451 Undefined symbol 'brvbar'

[sczyq]

你说怎么使用两个函数：

TList *NetCardList = new TList;
EunmNetCards(NetCardList);

// 列出
for (int i=0; i<NetCardList->Count; i++)
{
PNetCardStruct AStruct = (PNetCardStruct)NetCardList->Items[i];
Memo1->Lines->Add("---------------");
Memo1->Lines->Add("网卡序号：" + IntToStr(i));
Memo1->Lines->Add("网卡设备号: " + IntToStr((int)AStruct->Id));
Memo1->Lines->Add("网卡设备名: " + AStruct->Name);
if (AStruct->Disabled) Memo1->Lines->Add("状态: 禁用");
else Memo1->Lines->Add("状态: 启用");
}


// 删除由EunmNetCards分配的内存
for (int i=0; i<NetCardList->Count; i++)
delete (PNetCardStruct)NetCardList->Items[i];

[sczyq]

禁用序号为n的网卡:

NetCardStateChange(NetCardList->Items[n],false);

你得留言给他，他不是天天来的。

DDK那里有，我找了好几天了．发一个给我把，谢谢！[e-mail]
