Convert LPWSTR to string

Question

Function CommandLineToArgvW is giving me commandline arguments in LPWSTR type. I need these arguments in string. Would someone please tell me how to convert LPWSTR to string?
I'm using mingw.

Solution 1

Try to use following API functions :

1. WideCharToMultiByte

2. wcstombs

And comparision of both methods WideCharToMultiByte() vs. wcstombs()

Solution 2

std::string MyString = CW2A (L"LPWSTR STRING");

You need to include atlstr.h for CW2A

Solution 3

Let's say yout LPWSTR variable is myVarL:

wstring ws( myVarL ); 
string myVarS = string( ws.begin(), ws.end() );

should make what you want

std::wstring someParam = std::wstring(argv[0]);

The CW2A macro converts a wide character string to an ASCII string, so why are you sticking the result back into a wstring?

[Erik Aronesty]

What do you #include for CW2A?

[Louis Waweru]

@ErikAronesty atlstr.h

This will not properly deal with most of the possible characters in a wide string

This will not go well for japanese characters.
