VBA from Excel to PowerPoint (when both are open), problem with GetObject() - excel

Question

I need to automate moving stuff from excel into PowerPoint. I build put together a macro, which works fine and it is basically running in PowerPoint, accessing Excel, taking some range of nicely formatted tables, and pasting as enhanced metafile:
Function CopyFromExcelToPPT(excelFilePath As String, sheetName As String, rngCopy As String, dstSlide As Long, Optional shapeTop As Long, Optional shapeLeft As Long, Optional shapeHeight As Long, Optional shapeWidth As Long)
On Error GoTo ErrorHandl 'Handle Errors
'Set Variables and Open Excel
Dim eApp As Excel.Application, wb As Excel.Workbook, ppt As PowerPoint.Presentation
Set eApp = New Excel.Application
eApp.Visible = False
Set wb = eApp.Workbooks.Open(excelFilePath)
Set ppt = ActivePresentation
'Copy cells in Excel
wb.Sheets(sheetName).Range(rngCopy).Copy
'Paste into first slide in active PowerPoint presentation
ppt.Slides(dstSlide).Shapes.PasteSpecial ppPasteEnhancedMetafile
'Close and clean-up Excel
eApp.CutCopyMode = False
wb.Close SaveChanges:=False
eApp.Quit
Set wb = Nothing: Set eApp = Nothing
'Move the new shape if left/top provided
If Not (IsMissing(shapeTop)) Then
With ppt.Slides(dstSlide).Shapes(ppt.Slides(dstSlide).Shapes.Count)
.Left = shapeLeft
.Top = shapeTop
End With
End If
'Resize the shape if height/width provided
If Not (IsMissing(shapeHeight)) Then
With ppt.Slides(dstSlide).Shapes(ppt.Slides(dstSlide).Shapes.Count)
.Height = shapeHeight
.Width = shapeWidth
End With
End If
'Put them to the back
With ppt.Slides(dstSlide).Shapes(ppt.Slides(dstSlide).Shapes.Count)
While .ZOrderPosition > 2
.ZOrder msoSendBackward
Wend
End With
CopyFromExcelToPPT = True
Exit Function
ErrorHandl:
'Make sure to close the workbook and Excel and return False
On Error Resume Next
If Not (eApp Is Nothing) Then
wb.Close SaveChanges:=False
eApp.CutCopyMode = False
eApp.Quit
End If
CopyFromExcelToPPT = False
End Function
The problem is, that I need to run this like 80x, and after each 5 loads I need to run a macro in that source excel, which will update data. Therefor I tried to either keep excel open during this macro, and manually lunch that macro, or ideally incorporate all of this into this PowerPoint macro.
I tried different approaches, however, I am not able to make it work, I am getting always errors.
Firstly I tried to to create another function handling running macro, and eventually chain it together with main function in main sub:
Function CallTopsheetMacro(excelFilePath As String, sheetName As String)
On Error GoTo ErrorHandl 'Handle Errors
'Set Variables and Open Excel
Dim eApp As Excel.Application, wb As Excel.Workbook
Set eApp = New Excel.Application
eApp.Visible = True
Set wb = eApp.Workbooks.Open(excelFilePath)
wb.Run "'...\excel.xlsb'!macro_01"
wb.Wait (Now + TimeValue("0:00:10"))
'Close and saves Excel
wb.Close SaveChanges:=True
wb.Wait (Now + TimeValue("0:00:10"))
eApp.Quit
Set wb = Nothing: Set eApp = Nothing
MsgBox ("Done!")
CallTopsheetMacro = True
Exit Function
ErrorHandl:
'Make sure to close the workbook and Excel and return False
On Error Resume Next
If Not (eApp Is Nothing) Then
wb.Close SaveChanges:=False
eApp.CutCopyMode = False
eApp.Quit
End If
CallTopsheetMacro = False
End Function
But this functions did basically nothing, only opens and closes excel, waiting is not even reflecting. Then I tried with both sessions (main PowerPoint taking the pictures, and excel which is providing pictures and running macros) running, as I would avoid manually triggering macros and wasting time with open/close excels which is pretty bulky:
Function CallTopsheetMacroActive()
On Error GoTo ErrorHandl 'Handle Errors
'Set Variables and Open Excel
Dim eApp As Excel.Application
Set eApp = GetObject("..\excel.xlsb", "Excel.Application")
eApp.Visible = True
'Run macro
eApp.Run "'...\excel.xlsb'!macro_01"
MsgBox ("Done!")
Exit Function
ErrorHandl:
'Make sure to close the workbook and Excel and return False
On Error Resume Next
If Not (eApp Is Nothing) Then
wb.Close SaveChanges:=False
eApp.CutCopyMode = False
eApp.Quit
End If
End Function
This one is doing nothing. Then I tried to examine the syntax for GetObject, even with small testing scripts, but it is not working. I have even added references for scrrun.dll, as I have 64bit and it was suggested in couple of similar topics, but of no help. For a simple code like this:
Sub GetObject_Testing()
Dim MyExcel As Excel.Workbook
Dim MySheet As Worksheet
Dim MyFilePath As String
'Set MyExcel = GetObject("Excel.Application")
MyFilePath = "...\excel.xlsb"
Set MyExcel = GetObject(MyFilePath, "Excel.Application")
For Each MySheet In MyExcel.Sheets
Debug.Print MySheet.Name
Next MySheet
End Sub
I am getting run.time error 432 (file name or class name not found during automation operation).
I have no idea what I may be doing wrong, and just to make sure I am providing whole code, just in case I have some error somewhere.
Would appreciate any suggestions which will help to solve this.
PS: Doing this from PowerPoint, because when I tried to the same from Excel, I was getting error that there is not enough memory to start PowerPoint.
Thanks!
