We study the question for which Tychonoff spaces X and locally convex spaces E the space (Formula presented.) of continuous E-valued functions on X contains a complemented copy of the space (Formula presented.), both endowed with the pointwise topology. We provide a positive answer for a vast class of spaces, extending classical theorems of Cembranos, Freniche, and Domański and Drewnowski, proved for the case of Banach and Fréchet spaces (Formula presented.). Also, for given infinite Tychonoff spaces X and Y, we show that (Formula presented.) contains a complemented copy of (Formula presented.) if and only if any of the spaces (Formula presented.) and (Formula presented.) contains such a subspace.
