Question

我已经设法打开我的 powerpoint 模板，然后添加来自 excel 的图表，现在我试图用一个新名称保存它，但是我的代码总是失败。错误是

Run-time error '91': Object variable or With block variable not set

主码

Option Explicit

Public PPT As PowerPoint.Application
Public PPT_pres As PowerPoint.Presentation

Sub master()

Dim fileNameString As String

fileNameString = "C:\Users\Person\Desktop\Testfolder\Test1.pptx"

Call Module4.OpenPowerpoint

Call Module4.PasteCharts

PPT_pres.SaveAs fileNameString, 1 'ERROR HERE

PPT.Quit

End Sub

其中 Module4.OpenPowerPoint 是

Public Sub OpenPowerpoint()
    Set PPT = New PowerPoint.Application

    PPT.Visible = True
    Set PPT_pres = PPT.Presentations.Open(Filename:="C:\Users\Person\Desktop\Testfolder\Test - Template.pptx")

End Sub

过去的图表代码 - 这对不同的图表重复几次

Public Sub CopyPasteForecastTopGraph()
    If PPT Is Nothing Then Exit Sub
    If PPT_pres Is Nothing Then Exit Sub

    Dim rng As Range
    Dim mySlide As Object
    Dim myShape As Object
    Dim cht As Chart

    Set mySlide = PPT_pres.Slides(5)

    With mySlide
    .Select
    Set cht = ThisWorkbook.Worksheets("Forecast").ChartObjects("FcChart").Chart

       cht.CopyPicture Appearance:=xlScreen, Format:=xlPicture, Size:=xlScreen
       .Shapes.Paste.Select

        '''''''''''''''''''''''''''''''''
        'Paste as Chart and break link. '
        '''''''''''''''''''''''''''''''''
        'cht.ChartArea.Copy
        '.Shapes.Paste.Select


    'With .Shapes("HcChart")
        '.LinkFormat.BreakLink
    'End With

        PPT_pres.Windows(1).Selection.ShapeRange.Left = 35
        PPT_pres.Windows(1).Selection.ShapeRange.Top = 110
        PPT_pres.Windows(1).Selection.ShapeRange.Width = 720
        PPT_pres.Windows(1).Selection.ShapeRange.Height = 300

        End With

    'Clear The Clipboard
    Application.CutCopyMode = False
    Application.Wait (Now + TimeValue("00:00:01"))

End Sub

由于您没有显示 PasteCharts 的代码，因此很难判断。因为您为您的对象使用全局变量编码 PPT.quit 是可能的 "messy"，特别是当您不关闭 PPT_pres 并且始终在 Module4 中创建 Powerpoint 的新实例时。

要么完全摆脱全局变量并重构代码，要么尝试在发生错误的行之后按以下方式更改代码 ppt_pres.SaveAs fileNameString, 1

ppt_pres.Close
Set ppt_pres = Nothing
PPT.Quit
Set PPT = Nothing
