Przykład użycia EditPoint
Dodatki Visual Studio zostały zaniechane w programie Visual Studio 2013.Dodatki należy uaktualniać do pakietu rozszerzenia VSPackage.Aby uzyskać więcej informacji na temat uaktualniania, zobacz Często zadawane pytania: konwertowanie dodatków na rozszerzenia pakietu VSPackage.
Poniższy przykład tworzy TextDocument obiekt, dodaje do niego jakiś tekst, a następnie pokazuje niektóre EditPoint obiekty funkcji.
Przykład
Opis
Te funkcje są oparte o jeden ze znaków offsetowych, podczas gdy IVsTextView i podobne interfejsy są oparte na zerze.Metoda EditPoint jest jednobazowa, ponieważ jest przeznaczona do obsługi automatyzacji VB.
Aby uruchomić ten przykład, utwórz projekt programu Dodatku Visual Studio i w kreatorze określ, że należy utworzyć element menu Narzędzia.Gdy kompilujesz i uruchamiasz dodatek, kliknij odpowiednie polecenie w menu Narzędzia, aby uruchomić kod.
