and re-compile the source file._ UNICODE macro is used for the C Runtime header file, while UNICODE macro is used for the Windows header file. When compiling the source code module, these two macros must be defined at the same time.5. What Unicode data types are defined in Windows?Data Type descriptionWCHAR Unicode CharacterPWSTR pointer to Unicode stringPCWSTR pointer to a constant Unicode stringThe corresponding ANSI data types are CHAR, LPSTR, and

The following is the commonly used ANSI control code found. However, I have never succeeded in saving the control code and restoring the cursor position. I first use/033 [s to save the current cursor position, and then use/033 [X; YH to set the cursor position, and finally restore the cursor position/033 [U, however, the original location cannot be recovered. Do not understand. BBS supports the ANSI/3.64 c

Byte [] Buffer = New Byte [Client. receivebuffersize]; This . Isactive = True ; While (Client. getstream (). Read (buffer, 0 , Buffer. length) ! = 0 ){String data = System. Text. encoding.

NSI, UTF-8, Unicode, three encoded formats for character codes, one character can be encoded into ANSI, UTF-8, or Unicode format, and the three formats are only different in expression and represent the same content. ANSI, UTF-8, Unicode

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

example:Uses_conversion;Ptemp = w2a (wszsomestring ); Note the possible problems during conversion:Because ANSI is converted to Unicode, if a2w or multibytetowidechar (the first parameter is cp_acp) is used, the imported ANSI string is treated as a multi-bytes String Based on the default conversion table, if it is a Chinese character (Windows is a Chinese

) Use the w2a macro, for example:Uses_conversion;Ptemp = w2a (wszsomestring ); Note: If a2w or multibytetowidechar (the first parameter is cp_acp) is used to convert Unicode to ANSI, according to the default conversion table, the imported ANSI string is treated as a multi-bytes string. If it is Chinese (Chinese Windows is Chinese by default ), A byte greater than 0x87 may be considered as a Chinese

to pop up a dialog box with a "encoding" drop-down at the bottom. There are four options: ANSI, Unicode, Unicode big endian and UTF-8. 1) ANSI is the default encoding method. English files are ASCII encoded files, while simplified Chinese files are gb2312 encoded files (only for Windows Simplified Chinese versions, if they are traditional Chinese versions, big5
