Aby wiedzieæ, jak dane narzêdzie wykorzystaæ, trzeba dok³adnie siê z nim zapoznaæ.
I w³aœnie temu s³u¿yæ ma ta ksi¹¿ka. Dla niedoœwiadczonego czytelnika poznanie
„warsztatu pracy programisty” jest zawsze trudne, zw³aszcza gdy ma do czynienia
z czêsto nieczyteln¹ dokumentacj¹ (np. napisan¹ w jêzyku obcym). Rozbudowany spis
treœci, liczne przyk³ady zastosowania m.in. funkcji czy obiektów definiowanych przez
Visual Basic u³atwi¹ prze³amanie pierwszych lodów. Jednak zarówno pocz¹tkuj¹cy,
jak i zaawansowany programista znajd¹ w „Leksykonie” interesuj¹ce informacje.
Szczególnie wa¿ne jest to, ¿e nie zosta³ pominiêty opis interfejsu œrodowiska
programistycznego, co stwarza niepowtarzaln¹ szansê na uzupe³nienie wiadomoœci
o przyciskach i oferowanym menu.
Liczne uwagi i komentarze odautorskie stawiaj¹ tê ksi¹¿kê ponad przeciêtn¹ ocenê,
z jak¹ mog³yby siê spotkaæ inne publikacje przyjmuj¹ce formê leksykonu. Treœæ staje
siê ¿ywa i ³atwo przyswajalna, a sam proces programowania ³atwy i przyjemny — jak
zapewnia autor we wstêpie do ksi¹¿ki.
