  We study the influence of wetting on the capillary condensation for a simple
fluid in a pore-like geometry, where the reference system is an infinitely long
slit. The Corner Transfer Matrix Renormalization Group method has been extended
to study a two-dimensional Ising model confined in an L x L geometry with equal
surface fields. Our results have confirmed that in both geometries the
coexistence line shift is governed by the same scaling powers, but their
prefactors are different.
