string和CString均是字符串模板类,string为标准模板类(STL)定义的字符串类,已经纳入C++标准之中; CString(typedef CStringT > CString)为Visual C++中最常用的字符串类,继承自CSimpleStringT类,主要应用在MFC和ATL编程中,主要数据类型有char(应用于ANSI),wchar_t(unicode),TCHAR
以下用pcstr表示const char*(LPCTSTR),pstr表示char*(LPSTR),用cstr表示Cstring,用str表示string,i表示int string转char* 1.pcstr=str.c_str();//有"\0" 2.pcstr=str.data();//没有"\0" 3.str.copy(pstr,str.length(),0);//没有"\0",要先memset CString转char* 1.pstr=cstr.GetBuffer(0); 2...
CStringA stra(strw.GetBuffer(0));strw.ReleaseBuffer();std::string imgpath=stra.GetBuffer(0);stra.ReleaseBuffer();std::string->CString 例子：CString strMfc；std::string strStl=“test“;strMfc=strStl.c_str();AfxExtractSubString是截取字符串的函数，很好用，不过美中不足的地方在与...
float为:9 double:17;string类型的为:118 windows平台 函数集提供了精度的控制。可以按照要求输出小数点后固定格式的字符串。比如:125.000 (精确到小数点后3位)。 #include<boost/lexical_cast.hpp> #include<cmath> #include<iomanip> usingboost::lexical_cast; boolDouble2MFCStr(doubledValue, CString&str,in...

http://stackoverflow.com/questions/3381614/c-convert-string-to-hexadecimal-and-vice-versa You only need to convert the std::string to a CString, what is not difficuilt. Since you do not have any history in MFC why not using std::string instead of CString. Best regards Bordon Note: P...

1.i=atoi(_in const char* src); int转各种 1.cstr.format(); 2.itoa(_in int val,_out char* dst,_in int radix) 输出: 都可以cout直接输出 赋值: string可以接受CString,char* CString可以接受char* 加法: string可以加CString,char* CString可以加char* ...
