有两处问题，求教大家！

if (FAILED(DirectSoundEnumerate((LPDSENUMCALLBACK)DSEnumProc,(VOID*)&hWnd)))//此处有问题
{
EndDialog(hWnd,TRUE);
return (TRUE);
}

if (mmioRead(hmmio,(HPSTR)pAudio,bytesAudio) == -1) return false;//此处有问题

第一处报错：
e:\C++\Direct\Direct Sound\MechWarrior\Game.cpp(52): error C2440: “类型转换” : 无法从“overloaded-function”转换为“LPDSENUMCALLBACKA”

第二处报错：
干脆就Init不成功，窗口根本就不显示，注销后Init成功并显示窗口！

请教大牛！
