Question

有人在我公司制作了VBScript（。vbs）脚本。它打开和关闭某个应用程序，此应用程序有一个托盘图标，每次关闭（通过控制台杀死）应用程序托盘图标保持不变。因此，在运行脚本一两天后，应用程序中会保留数百万个应用程序图标。

VBScript中是否有指令刷新任务栏并删除这些图标？

这是scrpit：

*****************************************************************************************
' Progam Name: CheckConnection.vbs
' Program Purpose: This script check for an internec connection, the program pings to some domains,
'       wait some seconds (5 seconds) before the next try, if a domain is found, reset all counters,
'       and wait secondsBeforeNextCheck seconds before next check
'       If the programs raise nMaxRetriesBeforeStartProgram then kill the program that
'       manage the connection and start it again.
' Usage: This Script must be placed in ONE OF THE FOLLOWING PATHS
'   1) Start --> All Programs --> Start Up
'   2) HKLM\Software\Microsoft\Windows\CurrentVersion\Run
'   3)HKCU\Software\Microsoft\Windows\CurrentVersion\Run
'   4) Or you can create a task through:
'       Start --> All Programs --> Accessories-->System Tools --> Scheduled Tasks--> Add Scheduled Task
'       --> Follow the Wizard'
'   5) The program VZAccess Manager.exe must be configured to autoconnect through
'       Tools --> Preferences --> WWan --> Connect Options --> Automatically Connect (this must be checked)
'   6) Also to autorefresh the ip the vzaccess manager.exe must be configured with an script when c onnect.

Answer 1

将鼠标指针移到它们上方后，系统托盘中的孤立图标就会消失。我想这可以通过将WM_MOUSEMOVE消息发送到系统托盘窗口以编程方式完成，但VBScript无法访问Windows API。

我建议您使用一些外部实用程序刷新系统托盘并从脚本运行它。例如，CodeProject上有TrayIconBuster实用程序，可以每隔5秒清理一次托盘。（但它需要.NET Framework。）或者您可以自己编写类似的工具。

要从VBScript代码运行应用程序，您可以使用WshShell.Run或WshShell.Exec方法。您可以在脚本中找到示例。

使用vb调用bat文件，其中包含restart Explorer命令或reg file

Windows注册表编辑器版本5.00 [-HKEY_CURRENT_USER \软件\微软\的Windows \ CurrentVersion \ Explorer中\ TrayNotify] [HKEY_CURRENT_USER \ SOFTWARE \微软\的Windows \ CurrentVersion \ Explorer中\ TrayNotify]

使用VBScript for Windows刷新Windows TaskBar？
