如何将二维或一维数组作为ATL对象的接口参数，接口如何定义？

[guchan]

不使用MFC，所以不能用CArray，请教，如何做。

VARIANT

CComObject<CCdbRecordSet>* p = new CComObject<CCdbRecordSet>;
p->Init(astrInfo,auiNum);

IDispatch* pDisp;
p->QueryInterface(IID_IDispatch, (void**)&pDisp);
ATLASSERT(pDisp);
pretobj->vt = VT_DISPATCH;
pretobj->pdispVal = pDisp;

CCdbRecordSet是一个对象，可以任意定义！！当然也可以实现数组功能了：

void CCdbRecordSet::Init(const CStringArray &astrInfo, const CUIntArray &auiNum)
{
m_astrInfo.RemoveAll();
m_auiNum.RemoveAll();
m_astrInfo.Copy(astrInfo);
m_auiNum.Copy(auiNum);
}

STDMETHODIMP CCdbRecordSet::get_itemcnt(long *plretval)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())

*plretval = m_astrInfo.GetSize();
return S_OK;
}

STDMETHODIMP CCdbRecordSet::get_infoAt(long nitem, BSTR *psretval)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())

_bstr_t s = _T("");
if(nitem >= 0 && nitem < m_astrInfo.GetSize())
{
s = (LPCTSTR)m_astrInfo[nitem];
}
*psretval = s.copy();
return S_OK;
}

STDMETHODIMP CCdbRecordSet::get_numAt(long nitem, long *plretval)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())

*plretval = 0;
if(nitem >= 0 && nitem < m_astrInfo.GetSize())
{
*plretval = m_auiNum[nitem];
}
return S_OK;
}

( VARIANT *p_lppXXX )
{

SAFEARRAY * saRet = NULL;

}

[Phourm]

保存调用在进程内可以用
BYTE* int* 之类的指针来代替

用SAFEARRAY是好的选择
