Problem Source: http://www.cnblogs.com/del/archive/2008/11/22/1284923.html#1378410 Delphi 2009 uses multi-byte encoding (MBCS) by default. Delphi indicates tencoding. default. The following is an example of conversion between multi-byte encoding and Chinese characters: Unit unit1; interfaceuses windows, messages, sysutils, variants, classes, g

The code is as follows Copy Code byte conversionsfunction conversion ($size) {$KB = 1024; 1KB (Kibibyte, kilobytes) =1024b,$MB = 1024 * $KB; 1MB (Mebibyte, megabyte, abbreviation "trillion") =1024kb,$GB = 1024 * $MB; 1GB (gigabyte, Gigabyte, also known as "gigabit") =1024MB,$TB = 1024 * $GB; 1TB (terabyte, trillion bytes, too byte) =1024GB,$PB = 1

Internet host address CP from numbers-and-dots notation into binary data in network byte order. if the input is invalid, inaddr_none (usually-1) is returned. this is an obsolete interface to inet_aton (), described immediately above; it is obsolete because-1 is a valid address (255.255.255.255 ), and inet_aton () provides a cleaner way to indicate error return. the inet_addr function converts the network host address (for example, 192.168.1.10)

The conversion function of the file size unit in PHP is to convert the file size unit to KB, MB, GB, and other functionRealSize ($ size) {if ($ size lt; (1024) {return $ size. byte;} if ($ size lt; 1048576) {conversion function of the object Byte size unit in PHP ($ size1024, 2) File size unit

In network programming, the network byte sequence is big-Endian, while most PC systems are x86 processor series, x86 uses little-Endian, so you need Network data streams must be converted to local data streams in byte order. The standard library provides two functions, hlton () and nthl (), to support conversion. Hston (unsigned short) and hlton (unsigned long)

I. Mat type: matrix type, matrix.In opencv, mat is a multi-dimensional dense data array. It can be used to process common multidimensional data such as vectors and matrices, images, and histograms.Mat has three important methods:1. Mat MAT = imread (const string * filename); read the image2. imshow (const string framename, inputarray mat); displays the image3. imwrite (const string filename, inputarray IMG); Save the imageCompared with the cvmat and iplimage types, the mat type has stronger mat

Byte order conversion and reading of the structure position field value, bitfield Recently I encountered another problem several years ago. Mark it. For a cross-byte field, if the byte order of the environment before and after data transmission is different (LE-> BE, BE-> LE ), A simple call (ntohs/ntohl/htons/htonl)

In the previous article, the conversion of strings and byte Arrays can be found Code Page to ensure that the conversion is reversible, but in actual processing, there are still some details to note. The most important thing is the converted string. the encoding of each character may be different from the original encoding. Take code page 437 as an example, the c

The following small series will bring you a python string str and byte array conversion method. I think this is quite good. now I will share it with you and give you a reference. Let's take a look at the following small series to bring you a python string str and byte array conversion method. I think this is quite good

of machine. Therefore, when the network type is re-transmitted, all machines use the same transmission mode, that is, the data adopts the same byte sequence. If all vendors require that machine A be used (called the network byte sequence), machine B must provide a function to convert the local storage structure to the network byte sequence for transmission, whe
