尝试使用处理来捕获运行时错误-2147188160（80048240）

Question

我正在尝试使用On Error GoTo Handle来捕捉不一致的

  

运行时错误-2147188160（80048240）

我的代码从Excel模板生成4个powerpoint，保存并关闭它们。这是我在底部的实验性错误处理：

'Exit PowerPoint
PPT.Quit
Exit Sub

Handle:
If Err.Number = -2147188160 Then
    PPT.Quit
    MsgBox "Hey look I broke!"
End If
End Sub

但在我的测试中，当我遇到错误时，我没有收到任何错误消息，但我的代码也没有运行。这让我相信我是捕获错误，但其他东西没有被触发。我之前尝试解决错误的根本原因，但解决方案是在我的代码中添加Application.Wait，我觉得这是不必要的。

在一个完美的世界里，我只想抓住错误，关闭PowerPoint并让它立即重新运行代码。有什么见解吗？

编辑：在Absinthe的建议后，我能够debug.print确认错误号确实是-2147188160。我现在能够成功地运行代码，只有在发生错误时，我才能让PowerPoint退出 - 我必须自己关闭PowerPoint，然后我可以看到MsgBox在我的Excel屏幕上显示：

'Exit PowerPoint
PPT.Quit
Exit Sub

Handle:
Debug.Print Err.Number
If Err.Number = -2147188160 Then
PPT.Quit
MsgBox "Oh look I broke!"
End If

Answer 1

如果PowerPoint没有退出，可能是因为有一些公开的参考文献。由于错误，你处于一种奇怪的状态，所以我建议你杀死与主窗口句柄相关的进程（不会在异常状态下推荐这个）。

在这种情况下，您需要知道哪些PPT流程是由自动化启动的并将其杀死。

此过程在开始时（仅限PPT）和最后的流程获取流程，并终止新流程。

这可能是由于在宏运行时引发了另一个错误并带有另一个错误号的事实。为避免错过此错误，如果数字不是您想要的数字，则可以添加其他消息。

If Err.Number = -2147188160 Then
    PPT.Quit
    MsgBox "Hey look I broke!"

    MsgBox("Run-time error '" & Err.Number & "': " & Err.Description, vbCritical, "Error")
