Using Delphi to implement mail attachment and transceiver function

.connect (); Connecting to an SMTP serverIdsmtp1.authenticate;Idsmtp1.send (IDMESSAGE1); Sending mailboxes to the serverFinallyIf idsmtp1.connected then Idsmtp1.disconnect; Disconnecting from the serverEndEndAt this point, the mail messaging function is basically complete. To do a full-featured messaging management tool, you also need to join the Mail management feature. These functions are implemented primarily by manipulating files locally. This allows you to manage these messages in your own

Some special usages of TCP/UDP and transceiver interfaces

1.UDP the difference between using the Connect function and not using the Connect function* No longer use sendto/recvfrom, but only write/read or SEND/RECV, which means that the destination IP cannot be specified when sending and receiving data* Asynchronous errors raised by connected UDP are returned to the process in which they are located, while non-connected UDP does not receive asynchronous errors* Connected UDP has high transceiver efficiency. B

Switch Transceiver Principle

Switch Transceiver Principle: Working at the data Link layer, the switch has a very high bandwidth of the back bus and the internal switching matrix. All ports on the switch are hooked up to this bus. When the packet is received, the processing port looks for the in-memory MAC address (that is , the physical address in the serial EEPROM that is cured on the NIC ) to that port, which is sent to the destination port through the internal exchange matrix.

Simultaneous DDoS attacks caused by a large number of connections, resulting in a transceiver outage, a large area of user time out of the line

grab the bag ...I turned on the main switch mirroring mode, grasping the main interface data, so as to ensure that all the user's data, so as to facilitate the analysis3, waited for about 3 hours, when I was ready to give up, suddenly the user again abnormal fall off the line ... At this time the clutch software is also jammed ....I know that at this time a large number of packet attacks caused the computer to be unable to respond ... So now I can only wait.4, probably waited for half an hour o

Xilinx High-speed transceiver serdes in-depth research

First, why use SerDes Traditional source synchronous transmission, clock and data separation. At low rate (When the rate gets higher, it's going to be a problem.Because the transmission line delay inconsistency and jitter exists, the receiver can not correctly sampled data, to the point of the forbidden Eye graph.Then I thought about recovering the clock from the data to sample the data, the CDRThus there is no delay inconsistency, and a slight jitter does not affect the sampling (the recovered

Winsock Transceiver Broadcast Packet "Go"

Winsock Transceiver Broadcast PacketThe concept of a broadcast packageBroadcast packets are typically used for two reasons: 11 applications want to find a resource on the local network, and the application has no prior knowledge of the address of the resource.2 Some important features, such as routing requirements, send their information to all the neighboring machines found.The destination address of the broadcast information depends on the network o

Networkcomms V3 Synchronous Transceiver Data

The NETWORKCOMMS communication Framework is a communication framework written by the British C # language that lasted 6 years and was developed to be stable and reliable in performance.The core function of Networkcomms V3 is to some extent asynchronous in its own way.NETWORKCOMMS provides the functionality to synchronize the request data and get the corresponding corresponding, very simple.Try{ //Connection information classConnectionInfo ConnectionInfo =NewConnectionInfo ("127.0.0.1",10000);

STM32 's serial port DMA transceiver and the implementation of the double buffer

dma_clearitpendingbit (DMA1_IT_TC4); } }A few notes1) The use of a double buffer in this way, for the large amount of time is very effective, when processing a buffer data, another buffer can normally receive data2) TX DMA interrupt, can be similar to the operation of the operating system mutex, when an array is still sent, another array if the detection of a send, it is not able to send, otherwise the child data will be confused;3) If the DMA receives the way to adopt the circular

Three months-see the rookie's Daily growth (JS-Regular form &&phpmail transceiver)

The exploration of socket development--data protocol transceiver based on JSON format

Previously published two essays: "Socket Development Quest--the definition of basic class and public class" and "Socket Development quest-Data packet and unpacking", introduced the development of socket. This article continues to explore the technical aspects of using the JSON format as a socket transceiver protocol. Before, the received socket data after a rough parsing, is the predata type of data, this is a general data format, we need to further
