WM_NOTIFY消息参数问题

[yeaffadgasf]

WM_NOTIFY的响应函数的参数该怎么添加呢？
根据MFC源码：
case AfxSig_bNMHDRpl:
{
AFX_NOTIFY* pNotify = (AFX_NOTIFY*)pExtra;
ASSERT(pNotify != NULL);
ASSERT(pNotify->pResult != NULL);
ASSERT(pNotify->pNMHDR != NULL);
bResult = (pTarget->*mmf.pfn_bNOTIFY)(pNotify->pNMHDR, pNotify->pResult);
}
break;
case AfxSig_vwNMHDRpl:
{
AFX_NOTIFY* pNotify = (AFX_NOTIFY*)pExtra;
ASSERT(pNotify != NULL);
ASSERT(pNotify->pResult != NULL);
ASSERT(pNotify->pNMHDR != NULL);
(pTarget->*mmf.pfn_NOTIFY_RANGE)(nID, pNotify->pNMHDR,
pNotify->pResult);
}
break;
case AfxSig_bwNMHDRpl:
{
AFX_NOTIFY* pNotify = (AFX_NOTIFY*)pExtra;
ASSERT(pNotify != NULL);
ASSERT(pNotify->pResult != NULL);
ASSERT(pNotify->pNMHDR != NULL);
bResult = (pTarget->*mmf.pfn_NOTIFY_EX)(nID, pNotify->pNMHDR,
pNotify->pResult);
}
break;
既有2个参数的，又有3个参数的。对于WM_NOTIFY消息我该添加几个参数呢？难不成每次都跟踪一下源码。。。。
比如在做ToolTip的TTN_TEXTCALLBACK的处理的时候就有这个问题
