问题填空题

在窗体上画一个名称为Text1的文本框，然后画三个单选按钮，并用这三个单选按钮建立一个控件数组，名称为Option1。程序运行后，如果单击某个单选按钮，则文本框中的字体将根据所选择的单选按钮切换，如图所示，请填空。

Private Sub Option1_Click(Index As Integer) Select Case ______ Case 0a=“宋体” Case 1a=“黑体” Case 2a=“楷体_GB2312” End Select Text1.______=a End Sub

答案

参考答案：Index

解析：Font或FontName或Font.Name 本题考查对控件数组下标的理解。用于控件数组拥有相同的名称，所以必须用下标来访问控件数组中的不同元素。这个属性用 Index来表示。本题建立了单选按钮的控件数组，要求选择不同的单选按钮，则文本框中的字体将根据所选的单选按钮切换，所以在Select分支控制语句的Case后填：Index，表示不同的控件。第二处应把字体值赋给Text1的FontName属性，该属性确定文本框中文字的显示格式。Name属性为Font属性的子属性，故答案中的写法是等价写法。
