Set console title in C++ using a string
提问by popgalop
I would like to know how to change the console title in C++ using a string as the new parameter.
I know you can use the SetConsoleTitlefunction of the Win32 API but that does not take a string parameter.
I need this because I am doing a Java native interface project with console effects and commands.
I am using windows and it only has to be compatible with Windows.
我想知道如何使用字符串作为新参数在 C++ 中更改控制台标题。
我知道您可以使用SetConsoleTitleWin32 API的功能，但它不带字符串参数。
我需要这个，因为我正在做一个带有控制台效果和命令的 Java 本机界面项目。
我正在使用 Windows，它只需要与 Windows 兼容。

The SetConsoleTitlefunction does indeedtake a string argument. It's just that the kindof string depends on the use of UNICODE or not.
该SetConsoleTitle函数确实采用字符串参数。只是字符串的种类取决于是否使用UNICODE。
You have to use e.g. the _Tmacro to make sure the literal string is of the correct format (wide character or single byte):
您必须使用例如_T宏来确保文字字符串的格式正确（宽字符或单字节）：
SetConsoleTitle(_T("Some title"));
If you are using e.g. std::stringthings get a little more complicated, as you might have to convert between std::stringand std::wstringdepending on the _UNICODEmacro.
如果您使用例如，std::string事情变得有点复杂，因为您可能必须在宏之间进行转换std::string并std::wstring根据_UNICODE宏进行转换。
One way of not having to do that conversion is to always use only std::stringif _UNICODEis not defined, or only std::wstringif it is defined. This can be done by adding a typedefin the "stdafx.h"header file:
不必进行这种转换的一种方法是始终仅std::string在_UNICODE未定义时或仅std::wstring在已定义时使用。这可以通过typedef在"stdafx.h"头文件中添加 a 来完成：
#ifdef _UNICODE
typedef std::wstring tstring;
#else
typedef std::string tstring;
#endif
If your problem is that SetConsoleTitledoesn't take a std::string(or std::wstring) it's because it has to be compatible with C programs which doesn't have the string classes (or classes at all). In that case you use the c_strof the string classes to get a pointer to the string to be used with function that require old-style C strings:
如果您的问题是SetConsoleTitle不需要 a std::string(or std::wstring)，那是因为它必须与没有字符串类（或根本没有类）的 C 程序兼容。在这种情况下，您可以使用c_str字符串类的 来获取指向要与需要旧式 C 字符串的函数一起使用的字符串的指针：
tstring title = _T("Some title");
SetConsoleTitle(title.c_str());

string str(L"Console title");
SetConsoleTitle(str.c_str());
