You'd just search the 'BSTR' member like any regular UNICODE string, e.g.

CComBSTR cb;

//...

__bstr_t bstr ( ( BSTR) cb;)
wchar_t* pwsz = ( wchar_t*) bstr;

if ( wcsstr ( pwsz, L"GOTO)) {

   // string found
}

BTW, that works for ANSI also:

CComBSTR cb;

//...

__bstr_t bstr ( ( BSTR) cb;)
char* psz = ( char*) bstr;

if ( strstr ( psz, "GOTO)) {

  // string found
}


'__bstr_t' is a powerful little helper class.

thanks jkr..

does GOTO need quote surrounding or just the one?

Argh, forgot the closing double quote for the "GOTO" string literal :o)

CComBSTR cb;

//...

__bstr_t bstr ( ( BSTR) cb;)
char* psz = ( char*) bstr;

if ( strstr ( psz, "GOTO")) {

 // string found
}
