How to compare BSTR against a string in c/c++?

Question

wprintf(L\"Selecting Audio Input Device: %s\\n\", 
                            varName.bstrVal);

if(0 == strcmp(varName.bstrVal, \"IP Camera [JPEG/MJPEG]\"))...
         


        

Answer 1

I always construct _bstr_t wrappers around BSTRs. It makes things quite a bit easier and more idiomatic:

if(std::string("IP Camera [JPEG/MJPEG]") ==
                   static_cast( _bstr_t(varName.bstrVal) )
{
}
