MongoDB Java drivers have provided comprehensive operations, divided into three parts:
1. Common user operations
2. Administrator operations
3. oplog operations
You can add an eclipse testng plug-in and import the testng. jar package to the project.
This article describes the usage and precautions.
1. Connect a replica set (replica sets) into D:
The replica set is a mongo solution for stability and can implement read/write splitting. Here we introduce the java connection method of the replica s

CopyCode The Code is as follows: // Connection
$ Mem = new memcache;
$ Mem-> connect ("192.168.0.200", 12000 );
// Save data$ Mem-> set ('key1', 'this is first value', 0, 60 );$ Val = $ mem-> get ('key1 ');Echo "Get key1 value:". $ Val. "
// Replace Data$ Mem-> Replace ('key1', 'this

Create an instance of the udpclient class and call the connect method.
You can use any method provided in udpclient to send data to a remote device. The receive method can be used to receive data from a remote host.The udpclient method also allows you to send and receive multicast data packets. You can use the joinmulticastgroup method to reserve a udpclient to a multicast group. You can use the dropmulticastgroup method to cancel a subscription to udpclient from a multicast group.

TX-2440A Development Board started, very excited. The tutorial is also carefully read. But encountered a problem, the tutorial explains the use of H-JTAG to burn the entire board test program method, but did not talk about how to use J-link download, this allows me to use only J-Link (my notebook only has USB ports, no parallel ports, and no serial ports. Depressed...) people are quite speechless. Of course, I haven't fully watched the video tutorial yet. Maybe there is a way back. You can leave
Transfer large data volumes in Web ServicesAuthor: DongdongIn vs2005, 12000 records are queried and remotingformat = serializationformat. Binary is set;Re-serialization, transmitted through WebService, received by the client, and deserialized, is indeed much better than the direct transmission of dataset, not only in network transmission, even the local machine, performance improvement is also very obvious.
The following are the methods in WebService
