如何通过 VBA 显示 Windows 10 通知 Toast

Question

我想知道在 Windows 10 中通过 VBA 显示通知 Toast 的最简单方法。

我没有找到一个好的答案。我在这里找到了一种从 PowerShell 创建通知的非常简单的方法。但我无法让它从 VBA 工作，因为我没有找到一种使用 WScript.Shell 在一行中执行此操作的方法。

我尝试了多种方法来实现这一目标，但没有成功。您可以在下面找到我的最后一次尝试：

Public Sub Notify_Test()

Dim WsShell     As Object: Set WsShell = CreateObject("WScript.Shell")
Dim strCommand  As String

strCommand = """powershell.exe"" ^ "
strCommand = strCommand & "[reflection.assembly]::loadwithpartialname(""System.Windows.Forms"")"
strCommand = strCommand & "; [reflection.assembly]::loadwithpartialname(""System.Drawing"")"
strCommand = strCommand & "; $notify = new-object system.windows.forms.notifyicon"
strCommand = strCommand & "; $notify.icon = [System.Drawing.SystemIcons]::Information"
strCommand = strCommand & "; $notify.visible = $true"
strCommand = strCommand & "; $notify.showballoontip(10,""New Chat!"",""You have received New Chat!"",[system.windows.forms.tooltipicon]::None)"

WsShell.Run strCommand

End Sub

我想避免编写 .ps1 文件。有人可以帮我解决这个问题吗？

先感谢您！

感谢@Remko，我能够显示通知。

我做了一个函数来使其使用更简单：

Public Function Notify(ByVal title As String, ByVal msg As String, _
                    Optional ByVal notification_icon As String = "Info", _
                    Optional ByVal app As String = "excel", _
                    Optional ByVal duration As Integer = 10)
                    
'Parameters:
'    title (str):Notification title
'    msg (str):Notification message
'    notification_icon (str):Notification icon. Available options are: Info, Error and Warning
'    app (str):Process name of app you want to be display in the system tray icon
'    duration (int):Duration of notification in seconds

Const PSpath    As String = "powershell.exe"

Dim WsShell     As Object: Set WsShell = CreateObject("WScript.Shell")
Dim strCommand  As String

If notification_icon <> "Info" And notification_icon <> "Error" And notification_icon <> "Warning" Then
    notification_icon = "Info"
End If

strCommand = """" & PSpath & """ -Command " & Chr(34) & "& { "
strCommand = strCommand & "Add-Type -AssemblyName 'System.Windows.Forms'"
strCommand = strCommand & "; $notification = New-Object System.Windows.Forms.NotifyIcon"
strCommand = strCommand & "; $path = (Get-Process -id (get-process " & app & ").id).Path"
strCommand = strCommand & "; $notification.Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($path)"
strCommand = strCommand & "; $notification.BalloonTipIcon  = [System.Windows.Forms.ToolTipIcon]::" & notification_icon & ""
strCommand = strCommand & "; $notification.BalloonTipText = '" & msg & "'"
strCommand = strCommand & "; $notification.BalloonTipTitle = '" & title & "'"
strCommand = strCommand & "; $notification.Visible = $true"
strCommand = strCommand & "; $notification.ShowBalloonTip(" & duration & ")"
strCommand = strCommand & " }" & Chr(34)

WsShell.Run strCommand, 0, False

End Function

Public Sub Notify_Examples()

Notify "Insert Title Here", "Insert Your Message Here"
Notify "Insert Title Here", "Insert Your Message Here", "Warning"
Notify "Insert Title Here", "Insert Your Message Here", "Error", "outlook"

End Sub

我想做额外的观察。离开 PSpath =“powershell.exe”时什么也不会发生。我想这是因为我的用户不是管理员。我可以通过将 powershell.exe 复制到我的文档并将 PSpath 更改为“C:\Users\my_user\Documents\powershell.exe”来绕过此问题。也许你也遇到这种情况......

如果您坚持使用 PowerShell 执行此操作，则以下代码可以工作：

Public Sub Notify_Test()

Dim WsShell     As Object: Set WsShell = CreateObject("WScript.Shell")
Dim strCommand  As String

strCommand = "powershell.exe -Command " & Chr(34) & "& { "
strCommand = strCommand & "[reflection.assembly]::loadwithpartialname('System.Windows.Forms')"
strCommand = strCommand & "; [reflection.assembly]::loadwithpartialname('System.Drawing')"
strCommand = strCommand & "; $notify = new-object system.windows.forms.notifyicon"
strCommand = strCommand & "; $notify.icon = [System.Drawing.SystemIcons]::Information"
strCommand = strCommand & "; $notify.visible = $true"
strCommand = strCommand & "; $notify.showballoontip(10,'New Chat!','You have received New Chat!',[system.windows.forms.tooltipicon]::None)"
strCommand = strCommand & " }" & Chr(34)
WsShell.Run strCommand

End Sub

当然，它会短暂闪烁控制台（powershell）窗口
