About using the tow functions: AddIPAddress(...) and GetAdaptersInfo(...)

[Jonson]

the code as follow：
DWORD dwRet;
IP_ADAPTER_INFO adapterInfo;
ULONG ulSize = sizeof(IP_ADAPTER_INFO);
dwRet = GetAdaptersInfo(&adapterInfo,&ulSize);
if (dwRet == ERROR_SUCCESS)
{
USES_CONVERSION;
dwRet = GetAdapterIndex
(A2WadapterInfo.AdapterName),&m_ulIfIndex);
if (dwRet != NO_ERROR)
TraceErrorMsg(dwRet);
else
{
unsigned long ulNTEContext, ulNTEInstance;
dwRet = AddIPAddress(0xDC702AD5, 0xFFFFFF00,
m_ulIfIndex, &ulNTEContext, &ulNTEInstance);
if (dwRet != NO_ERROR)
TraceErrorMsg(dwRet);
}
}
else
TraceErrorMsg(dwRet);


Calling the GetAdapterIndex function always returns error
(error code = 55:The specified network resource or device
is no longer available)；
and calling AddIPAddress function always returns error
(error code = 87:The parameter is incorrect).

why? Thanks for any advise.

Jonson,

This is wrong NG for this type of questions but anyway:
You are trying to type cast and use ASCII adapter name in function that require wide character name.
Try using different approach or functions for obtaining adapter name.
