求一个关于下面这个 拼图游戏 的关键代码的说明
这是整个程序的开始程序：Private Sub Timer1_Timer()
Static a As Integer
If a < 100 Then
PICG.Show
End If
If a > 1 Then
Unload STUP
End If
a = a + 1

--------------------编程问答--------------------
就像是要求把这个程序讲解一遍 用VB的知识对运行的主要步骤进行分析说明
--------------------编程问答--------------------
这个的话，太费脑子了。要求别人帮忙，自己先要不懒哦。
补充：VB , 基础类
