Reading ANSI, Unicode, Unicode big endian, and UTF-8 text files by row in vc ansi Environment
1. Question proposal
The file class cstdiofile provided by MFC. One of the functions readstring implements row-based reading of files, but it cannot meet the needs of reading different types of text files by row. To solve this problem, I

Talking about the font application in web design. The second lecture is being prepared. We will meet you in a few days. A piece of news was inserted before that.
If you use various term software on BBS, you will not be unfamiliar with ANSI art and ASCII art. Many university BBS also have ANSI versions.
If you have a deeper understanding, in fact, this art form first began with the popul
Q How to display Unicode strings
A
If the program defines _ Unicode macro, directly use
Wchar * STR = l "unicodestring ";
Textout (0, 0, STR );
Otherwise, the conversion type is required.
# Include Wchar * STR = l "unicodestring ";
Bstr_t str1 = STR;
Textout (0, 0, (char *) str1 );

You can use the "--ansi" startup option to require MYSQLD to use ANSI mode.
Running the server in ANSI mode is the same as the effect of starting it with this option (specifying the "--sql_mode" value on one line):
--transaction-isolation=SERIALIZABLE --sql-mode=REAL_AS_FLOAT,PIPES_AS_CONCAT,ANSI_QUOTES, IGNORE_SPACE
In MySQL4.1, you can use the following two

As we know, C uses a char data type to represent a 8-bit ANSI character, and by default when a string is declared in the code, the C compiler converts the characters in the string into an array of 8-bit char data types:
Copy Code code as follows:
An 8-bit character
char c = ' A ';
An array of 8-bit character and 8-bit terminating zero
Char szbuffer[100] = "A String";
Microsoft's C + + compiler defines a built-in data ty

Integral upgrade in ANSI C
char,short int or int-bit segments (Bit-field), including their signed or unsigned variants, as well as enumeration types, can be used in an expression that requires an int or unsigned int, if the int can fully represent all the values of the source type. The value of that type is converted to int, otherwise it is converted to unsigned int.

What is ANSI and what is Unicode? In fact, this is the two different coding standards, ANSI characters in 8bit, and Unicode characters in 16bit. (for characters that say ANSI holds English characters in single-byte, double-byte for Chinese, and Unicode, both English and Chinese characters are stored in double-byte) Unicode code is also an international standard e

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

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
