How to convert std::wstring to a const TCHAR*?
To convert a std::wstring
to a const TCHAR*
, you can use the c_str()
member function of std::wstring
to obtain a pointer to the wide character string, and then use the TCHAR
data type based on the character set being used. Here's an example:
cpp#include <string>
#include <tchar.h>
int main()
{
std::wstring wstr = L"Hello, world!";
// Convert std::wstring to const TCHAR*
const TCHAR* tcharPtr = wstr.c_str();
// Use the const TCHAR* as needed
// ...
return 0;
}
In this example, wstr
is a std::wstring
containing a wide character string. The c_str()
member function returns a const wchar_t*
pointer to the internal wide character string representation of wstr
. To convert it to a const TCHAR*
, you can assign the result of c_str()
to a const TCHAR*
variable (tcharPtr
in this case).
The TCHAR
data type is defined based on the character set being used in your project. In a Unicode project (where UNICODE
is defined), TCHAR
resolves to wchar_t
. In a non-Unicode project, TCHAR
resolves to char
. The TCHAR
data type allows your code to be compatible with both ANSI and Unicode character sets.
Make sure to include the <tchar.h>
header to access the TCHAR
data type and related functions.
Please note that the conversion from std::wstring
to const TCHAR*
assumes that your project is configured for Unicode character set. If you are working with a non-Unicode project, you can consider using std::string
and const char*
instead of std::wstring
and const TCHAR*
.
