You asked me to reply on this, but there is nothing much to say, except to ask why you are not using proper string comparison functions. Also, why do you think that the strings "element" and "a" could ever be equal?

Solution 2

C++

if(0== wcscmp(var, L"a"))
  {
printf("they are equal\n")
                       
 }

Solution 1

A BSTR is just a pointer to a wide character string. So you must compare with a wide string and use a string compare function:

C++

if (0 == wcscmp(var, L"a"))
    printf("they are equal\n");
