某班级学生为毕业晚会的一个节目设计一个仿“V”字造型，先筛选出班级里所有男生，然后将参演的n名男生按照身高，摆出中间低两边高（先右后左）的造型，如图1 所示。王林同学用VB编写模拟“节目造型”程序，功能如下：从数据库中导出所有学生编号、性别和身高数据；单击“筛选排序”按钮Command2，根据身高仿“V”字和造型进行有序排列，并将结果显示在文本框Text2 中。程序运行界面如图2
所示。举例说明如下：

原1-7号男生身高	171 172 180 174 176 179 178
筛选排序后序列	171 172 174 176 178 179 180
“造型设计”后序列	180 178 174 171 172 176 179
