Keterangan
Properti Verbs memungkinkan Anda menentukan kata kerja yang dapat digunakan dengan file yang ditentukan oleh FileName properti . Anda dapat mengatur Verb properti ke nilai kata kerja apa pun dalam set. Contoh kata kerja adalah "Edit", "Buka", "OpenAsReadOnly", "Cetak", dan "Printto".
Ketahuilah bahwa daftar kata kerja yang dihasilkan mungkin tidak berisi semua nilai yang mungkin, misalnya "Baru" dirancang tidak ditambahkan ke daftar dan kemungkinan kata kerja lainnya tidak selalu terdeteksi tergantung pada penyiapan sistem Anda.
Saat Anda menggunakan Verbs properti , Anda harus menyertakan ekstensi nama file saat Anda mengatur nilai FileName properti . Ekstensi nama file menentukan kumpulan kemungkinan kata kerja.
