 Cast Object parameter 'byref'


I have a problem when objects are passed by reference (compare with VT_BYREF
in automation)

Simple sample

// this compiles but might give a object reference null exception
void blah(Object * anyvalue)
    // this does not always work
    Boolean myBool = *static_cast<__box Boolean *>(anyvalue);

    //??? why does this compile and work as well?
    Object * othervalue = __box(true);
    Boolean otherBool = static_cast<Boolean>(othervalue):

 Cast Object parameter 'byref'
it should be
    Boolean myBool = *dynamic_cast<Boolean *>(anyvalue);
