如何：將按鈕加入至 ToolBar 控制項

備註

ToolStrip 控制項會取代 ToolBar 控制項並加入其他功能，不過您也可以選擇保留 ToolBar 控制項，以提供回溯相容性及未來使用。

ToolBar 控制項的一個組成部分是您新增到其中的按鈕。 這些可用於提供對功能表命令的輕鬆存取，或者也可以將它們放置在應用程式使用者介面的另一個區域中，以向使用者公開功能表結構中無法使用的命令。

下列範例假設已將 ToolBar 控制項新增至 Windows Form (Form1)。

以程式設計方式新增按鈕

  1. 在程序中，藉由將工具列按鈕新增至 ToolBar.Buttons 集合來建立工具列按鈕。

  2. 透過 Buttons 屬性傳遞按鈕的索引，以指定個別按鈕的屬性設定。

    下列範例會假設表單中已新增 ToolBar 控制項。

    備註

    ToolBar.Buttons 集合是以零起始的集合，因此程式碼應該據以繼續。

    Public Sub CreateToolBarButtons()
' Create buttons and set text property.
   ToolBar1.Buttons.Add("One")
