These questions may be a little vague for many friends, so this article tries to explore the secrets behind them.
First of all, there is at least one thing to be sure that ANSI C guarantees that the positions of the fields in the structure are incremented in memory as they are declared, and that the first address of a field equals the first address of an entire struct instance. For example, there is a structural body:
Copy Code code as follows:
pass it an ANSI string, the system must first convert the string to Unicode, then, the Unicode string is passed to the operating system. If you want the function to return an ANSI string, the system first converts the Unicode string to an ANSI string and then returns the result to your application. To convert these strings, the system time and memory are require

Readers must use the internal code when entering and storing documents. The internal code is dividedSingle-byte internal code-- Single-byte character sets (sbcs), which can be 256 characters encoded.Double Byte internal code-- Double-byte character sets)
I have been confused about the above encoding. I checked some information and finally got a general idea of it.

// Today, I wrote a piece of code to output text to a file. At the beginning, I used cfile to output Chinese characters, which always showed garbled characters. Baidu (Google was walled, the tutorials on the Internet basically only know one of them, and most of them only focus on the attention points of the output file in the byte sequence mark and the calculated width character length, but do not mention the most critical step of charact
Unicode and ANSI string conversionsWe use the Windows function MultiByteToWideChar to convert multibyte strings to wide-character strings, as follows:int MultiByteToWideChar ( UINT ucodepage, DWORD dwFlags, pcstr pmultibytestr, int Cbmultibyte, Pwstr pwidecharstr, int cchwidechar);The Ucodepage parameter identifies a code page value associated with a multibyte string. The dwflags parameter allows us to take extra control, which affec

In addition, there is a clear difference between windows and the text file read and write, the line will be changed \ n automatically replaced \ r \ n.The final text files
Read and Write Unicode files in the ANSI environment of VC Programming
I did not notice that the differences in file encoding will cause so many problems. I have searched a lot of information before I started, and I have added many of my predecessors to my blog. I would like to pay tribute to them here!I will not talk about the principle of ANSI and Unicode encoding here. I will mainly talk about how to r
Create a UNICODE Code project
In VC60, the ANSI encoding project is created by default (Note: The resource characters of the compiled exe are saved in UNICODE). The UNICODE encoding project is created using the following method:
1. Add UNICODE and _ UNICODE preprocessing options for the project.Specific steps: open [project]-> [settings…] In the "pre-processing program definition" in the C/C ++ label dialog box, remove _ MBCS and add _ UNICODE and UNI

ANSI is a character code. To enable the computer to support more languages, 0x80 ~ is usually used ~ 2 bytes in the 0xFF range to 1 character.
