C++: Convert wchar_t* to BSTR?

Question

I\'m trying to convert a wchar_t * to BSTR.

#include 
#include 

using namespace std;

int main()
         


        

Answer 1

SysStringLen() should only be used on BSTRs allocated by SysAllocString() family functions. Using it as you do will lead to undefined behavior - program can crash or produce unexpected results. Better yet use wrapper classes - ATL::CComBSTR or _bstr_t.
