一个托盘图标类, 包括:
图标的动态更换、托盘气泡提示（多个类型）、工具提示、托盘图标重建、连带着把右键托盘菜单的问题一并加入解决；
自实现的窗口实现托盘消息管理
NotifyBar
.Icon（属性） 托盘图标属性，直接赋值图标, 具体可参考实例代码； 动态换图标由调用端联合 Timer 配合 Icon 属性自己实现即可
.HandleOfNotifybar（属性） 托盘图标的消息接受窗口句柄，这个窗口是自动创建的，非必须勿改，且如必须更改则应在显示图标之前调用此属性更改
.CallBackMessage（属性） 自定义托盘消息，非需勿改，有默认值
.ToolTipText（属性） 托盘图标的工具提示
.NotifyMsgBox（方法） 托盘的气泡提示: NotifyMsgBox (气泡通知内容， 气泡通知标题，气泡通知类型[包含4个类型的枚举，分别表示用不同的图标])
.NotifyBoxVisible（属性） 启用/停用 托盘图标，如果需要对 HandleOfNotifybar、CallBackMessage 属性自定义修改，则应该在此属性之前调用
NotifyClick （事件） 托盘图标鼠标事件，提供 MouseMove，LeftButtonClick，RightButtonClick，LBDoubleClick，4个事件
Private Sub sysNotifyBar_NotifyClick(NClickClass As NotifyClickClass, ByVal x As Long, ByVal y As Long)
'// 托盘图标事件
Select Case NClickClass
Case NCL_MouseMove: Debug.Print “这是鼠标 MouseMove 事件”
Case NCL_LeftButtonClick: Debug.Print “这是鼠标 左键点击 事件”
Case NCL_RightButtonClick: Debug.Print “这是鼠标 右键单击 事件”
Case NCL_DoubleClick: Debug.Print “这是鼠标 左键双击 事件”
'// 托盘图标事件
Select Case NClickClass
Case NCL_MouseMove: Debug.Print “这是鼠标 MouseMove 事件”
Case NCL_LeftButtonClick: Debug.Print “这是鼠标 左键点击 事件”
Case NCL_RightButtonClick: Debug.Print “这是鼠标 右键单击 事件”
Case NCL_DoubleClick: Debug.Print “这是鼠标 左键双击 事件”
'//Case 右键双击 因应用范围、方式等原因，该事件未提供, 如需要请自行修改 NotifyBar 类 MsgHook 过程的相关代码添加即可
End Select
End Sub
一般情况下，使用时，最后调用 NotifyBoxVisible 属性将托盘图标显示出来即可； 所有属性都支持动态修改;
系统资源管理器崩溃后，托盘图标会按照 NotifyBar 最后一次的记录的属性自动重建托盘图标.
