As3 uses AMFPHP to communicate with PHP from: bbs.9ria.comthread-65836-1-1.html? First, let's talk about the specific configuration: PHP version: 5.2.5, apache: 2.2.11, (or WAMP2.2), amfphp: 1.9 (attachment already provided), and Windows XP.

Phenomenon:[FreeBSD] Server can not communicate with the external network problems, prompted "Ping:sendto:No Buffer space available"The server cannot connect.Just started thinking that there was not enough resources1, restart, the problem remains.Start for a little while, ping any address and start the error again2, re-installed, the problem is still.3, the NIC switch to a socket, problem solving.Although not Cheng Zhang, but still detour, because see

define a new event binding function:JavascriptAngular. Module (' MyApp '). config ([' $provide ', function ($provide) {$provide.

by the android router to each simulator. Enter cmd, enter ipconfig, and directly use the IP address. Later, port ing was performed and telnet localhost 5554 using the command, Diret tcp: 5000: 6000 does not work either. Later, it was found that the request was forwarded on the two-day simulator and the information needed to be configured was not capable of communication between the simulator and the PC. Finally, I tried to write the port number as the simulator's port number. I am 5554 or 5556,

Today, we will introduce how Oracle databases use Java stored procedures to communicate with SQL, XML, and Java, J2EE, and Web services. If you are interested in the actual operations, the following articles will provide you with relevant knowledge. Stored procedure) allows you to effectively separate the persistence logic running on the database layer from the business logic running on the middle layer. This separation reduces the complexity of the e

Here is the. NET Named Pipes solution. Namedpipenative: This class communicates with Kernal32.dll to implement named Pipes, which contain some common methods and constants. Namedpipewrapper: This class is a wrapper for namedpipenative. Basepipeconnection: This is an abstract class that defines a method for naming pipes to connect, read, and write data. This class is inherited from Clientpipeconnection and serverpipeconnection, and is used in client and server-side applications, respe

I used two articles written in WP and unity to communicate with each other, the method of invocation, one is an event, one is a plug-in.This is a simpler one, and I think this should be a unique advantage of Unity's release to WP or WIN store. After all, they are C #.Too lazy to write so detailed.Specifically in unity inside the definition of a public static method, in WP directly can be called, hehe, and so on.This is usually the case when you save t

After the company builds the wireless network, the wireless client can communicate normally, but cannot communicate with Ethernet. The causes and solutions for this failure are as follows. The connection to the 1.LAN port is faulted. If this is the problem, you can check the LAN port connection to the Ethernet device and see if the LAN LEDs are lit. When a hub device is connected to a LAN port, th

ObjectiveSpeaking of communication between threads: According to my understanding, there are two main types.1. Is through the sharing of variables, between the threads through this variable for collaborative communication;2. Through the queue (which is essentially the same block of memory shared between threads) to implement consumer and producer patterns to communicate; 1. How variables are shared across threads It is necessary to say wait (), notify

This experiment needs: By planning VLAN 100 and VLAN 200 in Cisco Catalyst 3550来, and configuring DHCP to have the VLAN100 personnel computer obtain an IP address for 192.168.0.0/ 24, let VLAN200 market computer to obtain IP address for 172.16.0.0/24. Because the marketing department and the Ministry of Personnel because of business relationship, need two servers to communicate with each other, where also need to configure the VLAN in 3550 to

Communicate and match data with the backend (light up the stars), and the backend light up 1. In the project, I met the product evaluation page, which contains the product star rating. At that time, I only wrote out the results (that is, the user clicked a few stars to see a few stars ), When I handed over the page to my back-end colleagues, he said that it was meaningless for me to do so and he could not do it. At that time, my mind was a bit confuse
