Socket receives Big DataThe previous blog, that is, when the server sends the data to the client, which is larger than the data set by the client, the data remaining data sent by the data service will be present in the IO buffer, which will result in the integrity of the data we want to obtain.Solution Ideas:1, the large client to receive the size of the data, because the official recommendation can only receive 8k of data, the server sent over the da

1. Images smaller than 8K will be inline in the code directly in Base64, reducing the HTTP request one time.2. More than 8k? Then the direct File-loader packaging, there is no file-loader.

One: Stack of processesWhen the kernel creates a process, it creates the appropriate stack for the process while creating the task_struct. Each process will have two stacks, a user stack, exist in the user space, a kernel stack, exist in the kernel space. When the process runs in user space, the contents of the CPU stack pointer register are the user stack address, the user stack is used, and when the process is in kernel space, the contents of the CPU stack pointer register are the kernel stack

thrown, the input stream is not closed and you can continue reading the data through the Read method.If you set timeout to 0, it means that read will wait indefinitely until the server program closes the socket. This is also the default value for timeout. The read data timeout is set to 30 seconds, as in the following statement:Socket1.setsotimeout (30 * 1000);These two methods will throw socketexception exceptions when the underlying socket implementation does not support the So_timeout option

current operation is Numberfp.close ()Second, read and write to the file operation1. Normal Read and write operation (1) Read ([size]) Size: The length of the read, in bytes.If you do not specify a parameter, the entire content is read once, returned as a string, and there is a "\ n" symbol at the end of each line. (2), ReadLine ([size]) reads one line at a time, if given a size, it is possible to return only a portion of a line, returned as a string, and a newline character "\ n" at the end. A

So embedded development requires both hardware and software to understand the basic requirements. However, depending on the focus of the different embedded product development work can be categorized as follows:Hardware aspects:1, circuit design: Product schematic design, the need for logarithmic electrical mode electricity are more p

SQL Server Management, did you do a good job? These may help you with your work, and you may wish to take a patient look. 1. The database file has. mdf. ldf three kinds of files, MfD main database file, NDF is from the database file, LDF for log database files, each database MDF file only one, NDF file can have multiple. 2.

First, Prepare knowledge: Oracle's logical storage management. Oracle is divided into 4 granularity on logical storage: tablespaces, segments, extents, and blocks. (1) Block: Is the smallest granularity of storage units, now the standard block size is 8k,oracle every I/O operation is also done by block, that is, when Oracle reads data from the data file, is read how many blocks, not how many rows. Each block can contain multiple row. (2) Area: comp
