This article mainly introduces the difference between the text file and the binary file, the interested friend's reference, hope to be helpful to everybody.
From the file encoding method, the file can be divided into ASCII code files and binary code file two kinds.
ASCII files are also referred to as text files, whi
PHP program that uploads binary files in text mode. Currently, some websites automatically add Content-type: imagegif and other headers before the files, causing damage to the binary files. Therefore, when I write a file that is uploaded as a text file, the Content-type: image/gif header is automatically added in front
Label:JDBC supports the processing of text (CLOB) and binary (BLOB) files, such as accessing articles or images into a database. This is all solved by the idea of flow. Two demos to see how JDBC operates text and binary files. Clob: Package Com.wxisme.jdbcclob;

Binary File processing problems
When processing binary files, use the following method:
Binfile = open (filepath, 'rb') read binary files
Binfile = open (filepath, 'wb ') to write binary files
So what is the difference between the result of binfile = open (filepath, 'R?
There are two differences:
First, if you en
First, no file is strictly different from a text file or binary file. A file can be opened in either text or binary mode, the so-called text files and binary files are opened in different ways. However, in actual use, files that u

OverviewData persistence is divided into different ways, this chapter mainly briefly shows the data archiving (generally speaking serialization) and the way of writing XML text file. The XML text mode mainly uses the Nsarray or Nsdictionary WriteToFile method, and the data archiving uses the data archiving (serialization) such as Nskeyedarchiver/nskeyedunarchiver.results showProgram DisplayData fileNote the

Summarize the online search content:
1. When a file is written in text mode, the newline (/N) is extended to/R/n. When the file is read, it is automatically converted back.
2. the binary method does not perform any expansion, which is consistent with the read/write content.
3. The default value is text.

Today, I am not very clear about the programs written by others, that is, how to distinguish binary files from text files by using cfile In the MFC program.
First, let's talk about the differences between binary files and text files:

When fopen is opened using a file or binary file, the difference is:
On WindowsIf the file is opened in "text" mode, when the file is read, the system converts all "\ r \ n" to "\ n". When the file is written, the system converts "\ n" to "\ r \ n.If the file is opened in binary mode, neither the read/write operations will perform such conversion.On Unix/Linux
