VBA保存Powerpoint

Question

我已经设法打开了我的powerpoint模板，然后添加了excel的图表，现在我试图用一个新的名称保存它，但是我的代码总是掉下来。错误是

运行时错误'91'：对象变量或块变量未设置

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

其中模块4.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--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，所以很难分辨。因为在对象中使用全局变量来编码PPT.quit是“杂乱无章”的，特别是当您不关闭PPT_pres并始终在Module4中创建Powerpoint的新实例时。

要么完全摆脱全局变量并重新对代码进行重新分析，要么在错误发生的代码行ppt_pres.SaveAs fileNameString, 1之后尝试以以下方式更改代码

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