The creation rule for an event is that the type must be a delegate type, that is, the delegate instantiates the eventThe case code is as follows:Here are the two methods to be delegated later: Public classEventManager {//The first method Public voidADD (intIintj) {intres = i +J; MessageBox.Show (Res. ToString ()); } //a second method Public voidSayHello (intIintj) {MessageBox.Show ("Hello Word"+ (i*j). ToString ()); } }This is the creation of the delegate

PIM-DM intensive mode)The PIM intensive mode is the preferred configuration in the multicast routing protocol. This Protocol is strongly supported by Cisco and provides easy configuration and troubleshooting methods. Similar to DVMRP, the PIM intensive mode does not have the characteristics of flooding or deleting. Therefore, it can still be used as an option for configuring short-term protocols for wide-area multi-point transfer. Meanwhile, the PIM S

+ = Operator-= OperatorI learned about multicast delegation. Now let's talk about the + = Operator and the-= Operator.In our previous studies, we know that the + = Operator is used for auto-increment operations, but in the delegate, the + = operator has a new meaning.First look at an instance:First define a delegate typePublic delegate void del (int a, int B );Then define a delegate variable:Del delegate;Now, let's assume that we have the following me

1. ssmping implements the multicast ping function specified by the rfc6450: https://tools.ietf.org/html/rfc64502. Ssmping's source package can be downloaded from here: https://launchpad.net/ubuntu/trusty/+package/ssmping3. Unzip and then execute the make report on CentOS Linux with the following error:Ssmpingd.c:44:error:dereferencing pointer to incomplete typeThe workaround is to edit the makefile file and add the following line:CFLAGS + =-d_gnu_sour

　　Wow, the multicast is a P4P protocol based, multi-functional, personalized player software. WOW Multicast integrates a new player engine, and is free BT on-demand software, the user only through a maximum of 30 seconds of buffer time can directly watch the rich film and television programs. Wow, it's a wow. Later, a set of online and local video software, speaking of video playback software, compared to a

Use boost. signal Boost. signal provides a multicast delegation mechanism through which the observer mode can be easily implemented: Void print_sum (float x, float y){Std: cout } Void print_product (floatX, floatY){Std: cout } Void print_difference (floatX, floatY){Std: cout }Int main (){Boost: signal Sig. connect (print_sum );Sig. connect (print_product );Sig. connect (print_difference ); Sig (5, 3 );} The usage of the signal object is very simple.

If you are using. Net to develop a background system and want to view logs of multiple servers at the same time, you can use the UdpAppender of log4net to multicast log information, and then accept and view the log information on a desktop program.Therefore, an iTrace log is written to accept the viewer, source code The service program requires iTrace. layout. dll, which is used to format the log information. A Bug in log4net. Util. Transform causes

Unicast is the process in which frames with specific target addresses arrive at the target address from the source. For example, if you say "Xiaoyue" to Xiaoyue ", So only Xiaoyue promised you Multicast: the address that the frame is sent to a defined group. For example, you say, "All men are here. One hundred yuan ". A male will be here, and a female will not be here, because she will not care about you if she has no money. Broadcast: Send frames
