Question

VB 程序托盘的问题

Private Sub Form_Load()
If WindowState = vbMinimized Then
LastState = vbNormal
Else
LastState = WindowState
End If

AddToTray Me, mnuTray

SetTrayTip "VB Helper tray icon program"
End Sub
这个是让程序托盘显示菜单的内容, 也就是右击托盘图标弹出菜单,
我想使用 Me.PopupMenu Form2.mnuFile (mnuFile是菜单名)
的方法把另一个窗体Form2的菜单调用过来, 但是抱错, 请问如果更改才可以?

Answer 1

用 Visual Basic 2008 吧

有个 托盘 组件

祝你顺利
