如何在 Excel SAP 问题的另一个实例中连接到 OPEN 工作簿

Question

I tried to follow up with the topic here: How to connect to OPEN workbook in another instance of Excel

But I ran into a problem, I am not able grab the new instance name or path.

However I know I have open Excel window in another instance (opened from a SAP system) and when I open VBA editor in that SAP generated Excel file and I type: ? Thisworkbook.Path ? Thisworkbook.Path in immediate window I get nothing, no path is given and thus this solutions does not get the instance path.

What can I do to make it work?

My issue is that this: Set xlApp = GetObject("C:\Tmp\TestData2.xlsx") is not grabbing the workbook name (including This.workbook.name or activeworkbook.name )

Any idea how else I can make VBA code in instance 1 work with workbook in instance 2?

I only want to save it nothing more, I'm using Saveas option, or at least I try.

Have anyone had a similar issue?

Working with the Excel files downloaded from SAP is always problematic.

You can use the module below and add before the xls.Close SaveChanges:=False this line xls.SaveAs Filename:='Any name that you want after that just place a call in your code after downloading the Excel File with

Call Close_SAP_Excel("TestData2.xlsx")

And it should work fine.

Module:

#If VBA7 Then
  Private Declare PtrSafe Function AccessibleObjectFromWindow Lib "oleacc" ( _
    ByVal hwnd As LongPtr, ByVal dwId As Long, riid As Any, ppvObject As Object) As Long

  Private Declare PtrSafe Function FindWindowExA Lib "user32" ( _
    ByVal hwndParent As LongPtr, ByVal hwndChildAfter As LongPtr, _
    ByVal lpszClass As String, ByVal lpszWindow As String) As LongPtr
#Else
  Private Declare Function AccessibleObjectFromWindow Lib "oleacc" ( _
    ByVal hwnd As Long, ByVal dwId As Long, riid As Any, ppvObject As Object) As Long

  Private Declare Function FindWindowExA Lib "user32" ( _
    ByVal hwndParent As Long, ByVal hwndChildAfter As Long, _
    ByVal lpszClass As String, ByVal lpszWindow As String) As Long
#End If
