./Debug/1.txt 是不是路径正确，同时是否可以被打开

ThreadFun 直接return，没有解锁吧

[mirroatl187]

static UINT ThreadFun(LPVOID pParam) { g_cs.Lock(); int result =song_db_access.Connect(L"./Debug/1.txt");//为什么返回null值 打不开。。。 g_cs.Unlock(); return 1; } static UINT ThreadFun2(LPVOID pParam) { g_cs.Lock(); int result2 =song_db_access.Connect(L"./Debug/1.txt"); g_cs.Unlock(); return 1; }
