在命令按钮上放置图像和标题

  • 项目

以下示例使用 ComboBox 显示控件的图片放置选项。 每次用户单击列表选项时，图片和标题都会在 CommandButton 上更新。 此代码示例还使用 AddItem 方法填充 ComboBox 选项。

若要使用本示例，请将此示例代码复制到窗体的"脚本编辑器"中。 若要运行本代码，需要打开该窗体，以便激活 Open 事件。 确保该窗体包含：

  • 一个名为"Label1"的 Label 。

  • 一个名为"CommandButton1"的 CommandButton ，其 Picture 属性设置为使用您计算机上的图像。

  • 一个名为"ComboBox1"的 ComboBox 。

Dim Label1 
Dim CommandButton1
