我所用的代码是griefforyou在以前贴出来的一个转动的小闹钟，我又做了定时关机和定时报警的功能的菜单，
问题一：
如何能够点菜单出来一个弹出对话框呢？
问题二：
做好以后是灰色的？怎么改背景和颜色？


够菜的问题吧，谢谢大虾们~~~

代码如下：

End Sub

Private Sub Init()
Dim i As Integer

BaseX = Me.ScaleWidth / 2
BaseY = Me.ScaleHeight / 2

R = IIf(BaseX > BaseY, BaseY * 0.8, BaseY * 0.8)

For i = 0 To 360 Step 6
