I know there are already numerous posts on how to copy things from excel to ppt with VBA on this page (and many of those already helped me out) but I have a rather strange problem I haven't seen addressed:
The task is fairly standard: loop through an excel workbook with multiple sheets and copy all the charts contained in the workbook into a ppt presentation, one chart per slide and always the same layout. Below the code I use for this
Sub PPT_Example()
Dim pptApp As PowerPoint.Application
Dim pptPres As PowerPoint.Presentation
Dim sh As Worksheet
Dim ch As ChartObject
Set pptApp = New PowerPoint.Application
pptApp.Visible = True
Set pptPres = pptApp.Presentations.Add
pptPres.PageSetup.SlideSize = PpSlideSizeType.ppSlideSizeOnScreen16x9
For Each sh In ActiveWorkbook.Sheets
For Each ch In sh.ChartObjects
Dim pptSlide As Slide
Dim Title As Object
Dim Box As Object
Dim Txt As Object
Set pptSlide = pptPres.Slides.Add(pptPres.Slides.Count 1, ppLayoutBlank)
ch.Copy
With pptSlide.Shapes.Paste
.Top = Application.CentimetersToPoints(3.3)
.Left = Application.CentimetersToPoints(0.76)
.Width = Application.CentimetersToPoints(16)
.Height = Application.CentimetersToPoints(10.16)
End With
'Insert Box
Set Box = pptSlide.Shapes.AddShape(Type:=msoShapeRectangle, _
Left:=Application.CentimetersToPoints(17.1), _
Top:=Application.CentimetersToPoints(3.3), _
Width:=Application.CentimetersToPoints(7.22), _
Height:=Application.CentimetersToPoints(9.29))
Prop_Box.Name = "Box"
pptSlide.Shapes("Box").Fill.ForeColor.RGB = RGB(219, 233, 255)
pptSlide.Shapes("Box").Line.ForeColor.RGB = RGB(0, 102, 255)
'Insert the text box
Set Txt = pptSlide.Shapes.AddTextbox(Orientation:=msoTextOrientationHorizontal, _
Left:=Application.CentimetersToPoints(17.1), _
Top:=Application.CentimetersToPoints(3.3), _
Width:=Application.CentimetersToPoints(7.22), _
Height:=Application.CentimetersToPoints(9.29))
Txt.Name = "Txt"
pptSlide.Shapes("Txt").TextFrame.TextRange.Font.Size = 14
pptSlide.Shapes("Txt").TextFrame.TextRange.Font.Bold = msoCTrue
pptSlide.Shapes("Txt").TextFrame.TextRange.Font.Name = "Arial"
pptSlide.Shapes("Txt").TextFrame.TextRange.Text = "Sample Text"
'Clear the Clipboard
Dim oData As New DataObject 'object to use the clipboard
oData.SetText Text:=Empty 'Clear
oData.PutInClipboard
Next
Next
End Sub
Above code works fine if I use it on my toy example (2 sheets, 3 charts total) but not if I apply it to the real thing, which is a workbook with 10-15 sheets and 8 charts per sheet. There it starts as it should but at some (random?) point, the code stops and gives me this error message
Run-time error: Shapes (unknown member): Invalid request. Clipboard is empty or contains data which may not be pasted here.
I noted that the code crashed earlier, the more objects I put on the slides (which is why I left the text and the box in my example, although not strictly neccessary). Given that and the error message, I assumed the clipboard might not be cleared properly after each loop, so I put in a section to clear the clipboard but it didn't solve the issue.
Any ideas?
Cheers

After the chart is copied, try adding DoEvents and pausing the macro for a few seconds before pasting it into your slide. And the same thing after it's pasted into your slide.
So, for example, first add the following function to pause your code . . .
Sub PauseMacro(ByVal secs As Long)
Dim endTime As Single
endTime = Timer secs
Do
DoEvents
Loop Until Timer > endTime
End Sub
Then try something like this . . .
ch.Copy
DoEvents
PauseMacro 5 'pause for 5 seconds
With pptSlide.Shapes.Paste
DoEvents
PauseMacro 5 'pause for 5 seconds
.Top = Application.CentimetersToPoints(3.3)
.Left = Application.CentimetersToPoints(0.76)
.Width = Application.CentimetersToPoints(16)
.Height = Application.CentimetersToPoints(10.16)
End With
You may find through testing that you can pause for less than 5 seconds, maybe 3 seconds.
