Please tell me what is wrong? The program does not compile and sin on
"" source.GetLeight () + 1) "" and "LPCSTR (source)", how to fix it? Thank you very much!

    In std::string there is no GetLeight method, not even GetLength , so the compiler correctly curses. - VladD
  • So how to do it, I realized, but how to arrange? - Alego22
  • Checkout what? Here is a list of std::string methods: en.cppreference.com/w/cpp/string/basic_string - VladD

    Then read the basics urgently. Find a book on C ++ (namely a book, video tutorials are not rolling) and study it. For books, look for questions on this site, discussed an infinite number of times. When you understand how std::string differs from char* , you can start writing programs. - VladD

For MS-specific types, it is convenient to use the MSDN site or the local MSVS help. For example, on this page you can find that the type CString is contained in the header file "afx.h". http://msdn.microsoft.com/en-us/library/aa300688%28v=vs.60%29.aspx

To use the MFC tools (availability of the same header files), you need to make sure that by the menu of the Studio Project->имя_ΠΏΡ€ΠΎΠ΅ΠΊΡ‚Π° properties...->Configuration Properties->General->Project Defaults property " Use of MFC " is set to " Use MFS in a ... "

LPCSTR is not a class, but a synonym of type const char* (if you hover the mouse over this type, you can see a popup with the text typedef substitutions), read as L ong P ointer C onst S tring, that is, a long pointer to a constant string (in From the string - char arrays with an additional element - the null character '\ 0'). Therefore it is impossible to call the constructor like this. A string is created as always:

 LPCSTR str = "Sample text";

In this context, the C-style c_str() has the c_str() method for accessing the pointer to a string in the std :: string class, and the c_str() method for the CString.

 // для std::string source strcpy(chBuffer, source.c_str()); // для CString source strcpy(chBuffer, source.GetBuffer()); // для LPCSTR source strcpy(chBuffer, source);
