嘗試打開PowerPoint演示文稿時Excel VBA錯誤467

Question

代碼的目標 ：如果PowerPoint已打開並且搜索的演示文稿已打開，則對其進行更新。 如果演示文稿已關閉，則將其打開。 如果PowerPoint關閉，則創建一個新實例。

錯誤 ：過去兩個星期內，多個用戶在多台計算機上運行了該文件，今天，其中一位用戶收到以下錯誤消息：

運行時錯誤467：遠程服務器計算機不存在或不可用

在調試模式下突出顯示的行代碼 ：

Set ppPres = ppProgram.Presentations.Item(i)

您的代碼-以下摘錄-對我來說有點奇怪：

' check if PowerPoint instance is open
If ppProgram Is Nothing Then
    Set ppProgram = New PowerPoint.Application
    i = 1
Else
    If ppProgram.Presentations.count > 0 Then
        ppName = Mid(ppFullPath, InStrRev(ppFullPath, "\") + 1, Len(ppFullPath))
        i = 1
        ppCount = ppProgram.Presentations.count
        Do Until i = ppCount + 1
            If ppProgram.Presentations.Item(i).Name = ppName Then
                Set ppPres = ppProgram.Presentations.Item(i)
                GoTo OnePager_Pres_Found
            Else
                i = i + 1
            End If
        Loop
    End If
End If

ppProgram.Presentations.Open Filename:=PowerPointFile

' *** Getting the ERROR at the line below ***
Set ppPres = ppProgram.Presentations.Item(i)

OnePager_Pres_Found:
ppPres.Windows(1).Activate  ' activate the One-Pager Presentation in case you have several open, and the One_pager is currently not the app "on-focus"

如果打開了Powerpoint並顯示了一些演示文稿，但沒有打開所需的演示文稿（PowerPointFile），則在出現錯誤的那一行上，您要做什么？ （我等於Presentations.count）

我認為這是錯誤的，應該由之前在網上打開的ActivePresentation代替。

也許您可以對代碼進行一些重組，以使結構/案例處理更加清晰。
