窗口中的两个文本框为Txt_time和Txt_player,分别用于录入提交答案的时间和选手编号。组合列表框Combo1提供题目编号(A~H),录入时从中选择。检查框Chk_yn用于输入解答是否正确信息。当单击“确定”按钮(Cmd_comfirm)时,录入的提交信息加入列表框List1中,排名情况在列表框List2输出。单击“关闭”按钮时退出应用程序。 在开发过程中,需要编写的部分程序代码如下: 【程序】 Private Type info No As Integer ′选手编号 Num As Integer ′完成题目数量 Time As Integer ′完成题目的总用时 d(8)As Integer ′d用于记录提交第i个题目错误答案的次数 a(8)As Boolean ′a用于记录第i个题目是否已经提交正确答案 End Type Dim R(201)As info ′R[j]用于统计编号为j的选手提交答案的情况 Dim Maxlndex As Integer ′Maxlndex记录提交答案的选手中编号最大者 Private Sub Form_Load() For i = 1 to 8 Combo1.
