C++ convert from string to LPCWSTR As you know, std::string is char* type, while LPCWSTR ,LPWSTRor CString is wchar_t* as long as the Visual Studio configured as Unicode Characte...

string z = "Hello"; LPTSTR x = new TCHAR[z.size() + 1]; strcpy(x, z.c_str()); //Now x is a copy, but remember to delete the allocated memory once is not needed. BUT if UNICODE is #defined, then LPCTSTR becomes LPWSTR and then the above doesn't even compile. You'll hav...

其中LP的含义是长指针(long pointer),C的含义是常量(constant),W的含义为宽字符(wchar_t),T的含义为_T宏. LPSTR:一般长指针,可以与char*互换使用 LPTSTR:根据是否定义UNICODE来解释的长指针 LPWSTR:宽字符长指针,使用UNICODE编码 LPCSTR:常量长指针,表明这种实例的内容无法被改变 ...
printf在指定了%s，要求变参中的参数为char*，说白了是个地址，而s虽然实际运行时被转化成地址，不过编译器检查类似这样的不正确调用(这里仅接受处理对string类型的操作)，因为类型不匹配会引起很严重的问题(破坏结构的内部格式或是超范围读写)，这对于指针访问来说简直是个灾难，编译器不能保证这一操作...
