The CString class +// specified here is compatible with other compilers such as Borland 5.5 +// and MinGW. + +// Differences between this class and the MFC/ATL CString class +// ------------------------------------------------------------ +// 1) The constructors for this class accepts only TCHARs. The various text conversion +// functions can be used to convert from other character types to TCHARs. +// +// 2) This class is not reference counted, so these CStrings should be passed as +// references or const references when used as function arguments. As a result there +// is no need for functions like LockBuffer and UnLockBuffer. +// +// 3) The Format functions only accepts POD (Plain Old Data) arguments. It does not +// accept arguments which are class or struct objects. In particular it does not +// accept CString objects, unless these are cast to LPCTSTR. +// This is demonstrates valid and invalid usage: +// CString string1(_T("Hello World")); +// CString string2; +// +// // This is invalid, and produces undefined behaviour. +// string2.Format(_T("String1 is: %s"), string1); // No! you can't do this +// +// // This is ok +// string2.Format(_T("String1 is: %s"), (LPCTSTR)string1); // Yes, this is correct +// +// Note: The MFC/ATL CString class uses a non portable hack to make its CString class +// behave like a POD. Other compilers (such as the MinGW compiler) specifically +// prohibit the use of non POD types for functions with variable argument lists. +// +// 4) This class provides a few additional functions: +// b_str Returns a BSTR string. This an an alternative for casting to BSTR. +// c_str Returns a const TCHAR string. This is an alternative for casting to LPCTSTR. +// GetErrorString Assigns CString to the error string for the specified System Error Code +// (from ::GetLastErrror() for example). +// GetString Returns a reference to the underlying std::basic_string<TCHAR>. This +// reference can be used to modify the string directly. + + + +#ifndef _WIN32XX_CSTRING_H_ +#define _WIN32XX_CSTRING_H_ + + +#include "wincore.h" + + +namespace Win32xx +{ + + class CString + { + // friend functions allow the left hand side to be something other than CString + friend CString operator + (const CString& string1, const CString& string2);
