It has been shown by Paczyński that gravitational microlensing is potentially a useful method for detecting the dark constituents of the halo of our galaxy, if their mass lies in the approximate domain 10-6 < M/M\odot < 10-1. Microlensing observations now under way monito several millions of stars in the Large Magellanic Cloud and in the Galactic Bulge. Here I discuss the main features of the microlensing events: in particular their rates and probability, taking also into account a possible flattened shaper for the halo.
