代码设计:

Dim bcb1 As Boolean
Dim bcbs As Boolean
Dim bcbe As Boolean
Dim tm As Integer
Dim intpart As Integer
Public IsBeginS As Boolean

' 以下代码是用来把在数据库的所有不同的车站显示在起始站中
' 其思路是如果在启动界面中，用户选择了更新数据库，则扫描整个数据库，并把不同的车站加到起始站中
' 并把这些车站名存放在一文本框中，以用于下次读取
' 如果用户没有选择更新数据库，则直接从文件中读取车站存放在起始站中
' 这样做的好处是可以大大提高效率，如果每次启动都要重新检索数据库，则要花费大量的时间
