UNICODE: Wide-Byte Character Set 1. How to obtain the number of characters in a string that contains both single-byte and double-byte characters? You can call the Runtime Library of Microsoft Visual C ++ to contain the function _ mbslen to operate

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 =

ANSI and UINCODE encoding, ANSIUINCODE EncodingBrief description: 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. Uincode (Uniform Code, universal

Do VC ++ development inevitably multi-byte Unicode, UTF-8 conversion, below I wrote a few character Conversion Function 1. Conversion of tchar and Char. The Unicode and multi-byte types of tchar are respectively wchar and char functions as

A solution to the problem of Chinese character file names is to convert cstring to char * in Unicode and use widechartomultibyte for conversion. There are many articles about the conversion of cstring to char * methods in UNICODE, but most of them

1. In the resource view, create a new Resource dialog and add a class to the dialog box to set the class name to Sqldlg. 2. Drag to add Edit control and button controls in the dialog box and modify their IDs. 3. Add the following code in the

One, CString turn char * CString pb=_t ( " abc " ); int len = WideCharToMultiByte (Cp_utf8, 0 , PB, Pb. GetLength (), NULL, 0 char * pa = new char [len + 1 ]; Len = WideCharToMultiByte (Cp_utf8, 0 , Pb, Pb. GetLength (), PA, len + 1

1 stringANSItoUTF8 (Const Char*Stransi)2 {3 //gets the buffer size required after converting to a wide byte, creating a wide-byte buffer, 936 for the Simplified Chinese GB2312 code page4 intNlen = MultiByteToWideChar (CP_ACP, NULL, Stransi,-1

The conversion method for Unicode, Utf-8, gb2312 Three encoding formats using vc++6.0 in the Windows Development environment:[CPP]View Plaincopy #include #include #include Using namespace std; void UnicodeToUTF8 (const wstring

Here two functions to achieve GB2313 and UTF8 format, mainly for VC + + in the acquisition of Web page content to solve garbled problem, because VC + + default character set is GB2312, the General Chinese web site may return is UTF-8 encoding, so

Normal sting type UTF-8 encoded format string std::string Ofdewarserver::string_to_utf8 (const std::string & str) { int nwlen =:: MultiByteToWideChar (CP _ACP, 0, Str.c_str (),-1, NULL, 0); wchar_t * Pwbuf = new Wchar_t[nwlen + 1];//must add 1,

VC + + in the Sqlite3.dll interface to the SQLite database operation, including open the database, insert, query database, etc., if the operation interface input parameters include Chinese characters, will cause an operation exception. For example,

Today's task is to save a file. It usually depends on how others write data. I just read it myself, but I haven't written it myself. I don't know much about the parameters of each API. When I was using it today, I encountered some problems. Let's

Recently, I made an Internet Explorer plug-in to get text from the webpage and encode it into a URL. In the previous article "Chinese URL encoding", we roughly introduced the URL encoding rules and the process of Chinese URL encoding, but how to

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

Summarize the various types of Unicode conversions that have recently been used, and encounter additional additions in the future:1. String Turn CStringString a= "abc";CString str=cstring (A.c_str ());Or Str.format ("%s", A.c_str ())2, int turn

Ansi string we are most familiar with, English occupies one byte, Chinese characters 2 bytes, ending with a \ 0, commonly used in txt text files.Unicode string. Each character (Chinese character or English letter) occupies 2 bytes. In the VC ++

In the engineering properties of VS we often set character set:In order to support Unicode encoding, it is necessary to convert between multibyte and wide bytes. There are two functions involved:int widechartomultibyte( _in_ UINT CodePage,

1. String Turn CStringString a= "abc";CString str=cstring (A.c_str ());Or Str.format ("%s", A.c_str ())2, int turn CStringInt A;CString Cstr;Cstr.format (_t ("%d"), a);3, Char turn CStringCstring.format ("%s", char*);Cases:Char szpath[];CString Cstr;

Except for basic non-pointer types (such as ing, long, And bool), other parameters passed in through the COM interface must use the specific COM type --For strings, The BSTR type should be used. This type is a fuzzy type. Microsoft does not disclose
