Abstract: Let $ S$ be a locally compact Hausdorff space, $ E$ a linear subspace of $ C(S)$. It is shown that the unit ball of $ E$ is compact in the strict topology if and only if both of the following two conditions are satisfied: (1) $ E$ is the Banach space dual of $ M(S)/{E^0}$ in the integration pairing, and (2) the bounded weak star topology on $ E$ coincides with the strict topology. This result is applied to several examples, among which are $ {l^\infty }$ and the space of bounded analytic functions on a plane region.
