求帮助看看这段代码是不是有问题，一直提示转换错误.

代码

char szMagicQuest[1024] = {0,};
qry->GetStr("m_aMagicQuest",szMagicQuest);
if(VerifyString(szMagicQuest,__FILE__,__LINE__,lpDbOverlappedPlus->AccountInfo.szPlayer,NULL) == FALSE)
{
    return;
}
CountStr = 0;
while('$' != szMagicQuest[CountStr])
{
    nEventId = GetIntPaFromStr( szMagicQuest, &CountStr );
    nDesc = GetIntPaFromStr( szMagicQuest, &CountStr );
    nCount = GetIntPaFromStr( szMagicQuest, &CountStr );

    nMagicDay = GetIntPaFromStr( szMagicQuest, &CountStr );
    CountStr++;
    //Error("%d %d %d %d %d %d %d %d [%d/%d]",nEventId,nX,nY,nCount,nDesc,nMagicDay,chElem,bLow,CountStr,nStrLen);
