Label 控件 Label 控件用于在窗體或其他容器中顯示標(biāo)簽，它通常用于識(shí)別其他控件，用來說明它們的意義或用法，還可以用于顯示標(biāo)題、說明性文字或幫助信息等。 xii. TextBox 控件 Text Box 控件用來在程序中提供一個(gè)文本框，可以顯示或輸入文本，它也是程序用戶進(jìn)行交互的常用方式，比如要求用戶輸入密碼、查詢條件等，甚至允許用戶進(jìn)行大段的文本編輯操作。 xiii. Fram 控件 該控件的任務(wù)是在窗體中繪制一個(gè)很有立體感的框架，常用的屬性是 Caption 屬性，用以顯示框架的標(biāo)題與其它空間配合好似用，使窗體布局看起來整齊，美觀。 xiv. Command Button 控件 是一種常用的控件，主要有 Caption 屬性，它決定顯示在命令按鈕上的文字， Click 事件是最常用的事件。 xv. ComboBox 控件 它融合了 TextBox 和 ListBox 控件兩者的功能，既允許用戶鍵入新內(nèi)容，又允許用戶在列表中進(jìn)行選擇，常用的事件有 Click 和Change 事件。 xvi. WebBrowser 控件 是一個(gè) Activex控件通過它可以把 Inter的瀏覽功能加到應(yīng)用程序中，在 Visual Basic 的窗體上顯示 Web 文檔，最常用的方法是Navigate 方法，該方法用來移到 URL或打開 HTML 文件。 xvii. SS Tab 控件 能在窗體上產(chǎn)生文件夾標(biāo)記效果，通過該控件的“屬性頁”對話框，設(shè)計(jì)所需要的框架，使界面有層次感。 xviii. Data 控件 主要用于數(shù)據(jù)庫內(nèi)容的綁定，主要屬性有 Connect, Database Name, Record Source 屬性。 xix. MsFlex Grid 控件 主要用于顯示數(shù)據(jù)庫表的記錄主要用于非綁定的形式，若和 Data 控件連接使用，只能用于瀏覽數(shù)據(jù)，保證用戶數(shù)據(jù)的安全。用 Allow Add等屬性實(shí)現(xiàn)在控件中加入、刪除記錄等功能。 xx. 菜單編輯器： 打開方式： 3. 從 VB “工具”菜單中，單擊“菜單編輯器”命令； 4. 直接單擊標(biāo)準(zhǔn)工具欄中的“菜單編輯器”按鈕； 使用鍵盤快捷鍵 Ctrl + E。 Are you hungry now? No, I am tired and lazy now。 if I pursue you I will not catch you, and if I catch youthrough your own slowness and clumsinessI will not kill you, and if I kill you I will not eat you. Nicholas had begun to back away, and at the last。 words, realizing that they were a signal, he turned and began to run, splashing through the shallow water. Ignacio ran after him, much helped by his longer legs, his hair flying behind his dark young face, his square teetheach white as a bone and as big as Nicholas39。s thumbnailshowing like spectators who lined the railings of his lips. Don39。t run, N icholas, Dr. Island said with the voice of a wave. It only makes him angry that you run. N icholas did not answer, but cut to his left, up the beach and among the trunks of the palms, sprinting all the way because he had no way of knowing Ignacio was not right behind him, about to grab him by the neck. When he stopped it was in the thick jungle, among the boles of the hardwoods, where he leaned,.。 out of breath, the thumping of his own heart the only39。 . sound in an atmosphere silent and unwa ked as Earth39。s long, prehuman day. For a time he listened for any sound Ignacio might m ake searching for him。 there was none. He drew a deep breath then and said, Well, that39。s over, expecting Dr. Island to answer from somewhere。 there was only the green hush. The light was still bright and strong and nearly, shadowless, but some interior sense told him the day, was nearly over, and he noticed that such faint shades as he could see stretched long, hor izontal distortions of their objects. He felt no hunger, but he had fasted be39。 fore and knew on which side of hunger he stood。 he was not as strong as he had been only a day past, and by this time next day he would probably be unable to outrun Ignacio. He should, he now realized, have eaten the monkey he had ki lled。 but his stomach revolted at the thought of the raw flesh, and he did not know how he might build a fire, although Ignacio seemed to have done so the night before. Raw fish, even if he were able to catch a fish, would be as bad, or worse, than raw monkey。 he remembered his effort to open a coconuthe had failed, but it was surely not impossible. His mind was hazy as to what a coconut might contain, but there had to be an edible core, because they were eaten in books. H e decided to make a wide sweep through the jungle that would bring him back to the beach well away from Ignacio。 he had several tim es seen coconuts lying in the sand under the trees. He moved quietly, still a little afraid, trying to think of ways to open the coconut w hen he found it. He imagined himself standing before a large and raggedly faceted stone, holding the coconut in both hands. He raised it and smashed it dow n, but when it struc k it was no longer a coconut but Maya39。s head。 he heard her nose cartilage break with a distinct, rubbery snap. Her eyes, as blue as the sky above Madhya Pradesh, the sparkling blue sky of the egg, looked up at him, but he could no longer look into them, they retreated from his own, and it came to him quite suddenly that Lucifer, in falling, must have fallen up, into the fires and the coldness of space, never again to see the warm blues and browns and gre
