whether to forward multicast packets to their networks. When a multicast router receives a multicast group, it checks the Message ID and forwards the packet only when the group has members. IGMP provides the information required at the final stage of forwarding Multiple Multicast packets to the destination. Multicast routers exchange information with each other, which is collected from members of the group of hosts directly connected to them. The algorithms used to exchange route information be

and scattered in the network, and the network cannot provide sufficient transmission bandwidth, for example, a large number of users in many different regions are connected over ISDN lines on the Internet. In this case, broadcast will waste a lot of unnecessary network bandwidth, which may cause serious network performance problems. Therefore, the IP Multicast Routing Protocol in Sparse Mode must rely on technologies with routing selection capabilities to establish and maintain multicast trees.

To implement hooks in VB, it must be set to 0. Dwthreadid can be set to app. threadid in thread hook VB. Lpfn is the hook function. In VB, you can use addressof to obtain the address of the hook function. This function varies depending on the hook type. For example, the keyboard hook is: Public Function keybo

, your program may collapse. MFC uses CBT hooks to monitor the creation of Windows. Windows will call this CBT hook with Hcbt_createwnd as soon as you create a window. MFC handles Hcbt_createwnd through a subclass window, and it is attached to its CWnd object. The details are more complex, and here's a simple version of the code: // 来自　wincore.cpp 的简化代码 LRESULT _AfxCbtFilterHook(int code, WPARAM wp, ...) {

When an object parameter is added to a type constraint, it can still have a default value, which becomes an optional parameter. If so, the inside of the function is to determine whether the passed parameter is null. However, it is generally not necessary to use the instanceof operator.
