在窗体上有一个名称为Check1的复选框数组(含4个复选框)，还有一个名称为Textl的文本框，初始内容为空。程序运行时，单击任何复选框，则把所有选中的复选框后面的文字罗列在文本框中(见图)。下面能实现此功能的事件过程是? A． Private Sub Check1_click(Index As Integer) Text1.Text = "" For k = 0 To 3 If Check1(k).Value = 1 Then Text1.Text = Text1.Text & Check1(k).Caption & " "?'双引号中是空格 End If Next k End Sub B． Private Sub Check1_Click(Index As Integer) For k = 0 To 3 If Check1(k).Value = 1 Then Text1.Text = Text1.Text & Check1(k).Caption & " " '双引号中是空格 End If Next k End Sub C． Private Sub Check1_Click(Index As Integer) Text1.Text = "" For k = 0 To 3 If Check1(Index).Value = 1 Then Text1.Text = Text1.Text & Check1(Index).Caption & " " '双引号中是空格 End If Next k End Sub D． Private Sub Check1_Click(Index As Integer) Text1.Text = "" For k = 0 To 3 If Check1(k).Value = 1 Then Text1.Text = Text1.Text & Check1(k).Caption & " " '双引号中是空格 Exit For End If Next k End Sub?
