Question

I am trying to concat a LPCWSTR and a char[] (and get LPCWSTR as output).

How can I do that?

Answer 1

You could convert your char[] array into a wide-char array using the following code (from MSDN)

wchar_t * wcstring = new wchar_t[strlen(array) + 1];

// Convert char* string to a wchar_t* string.
size_t convertedChars = 0;
mbstowcs_s(&convertedChars, wcstring, strlen(array) + 1, array, _TRUNCATE);

After that you can use wcscat_s to concatenate the converted character array to your original LPCWSTR.
