Excel VBA copy content from one Sheet into other Workbook sheet - excel

Question

I want to be able to select a workbook and then copy the content from that workbook (sheet 1) into my current active workbook where I run the macro. I've been looking at some answers here on StackOverflow to similar questions and got the following code (see below).
The selection of a file is currently working fine, but when I run the macro it throws an error
Runtime error "438": Object does not support that method or property`
(please note, that the error comes in my native language and is just translated by me)
Sadly no object is marked that he relates to, so I can't really make out what problem he has. Yet, I guess it is a problem with the PasteSpecial in the last line of function GetTemplateData, but that code should be alright (what is it supposed to do? Save the data into the first sheet of the give workbook activeWorkbook) and pass the reference back go GeneratedValues-routine.
Option Explicit
Private Sub GenerateValues()
'Application.ScreenUpdating = False
'Application.DisplayAlerts = False
Dim activeWorkbook As Workbook
Dim activeWorksheet As Worksheet
Set activeWorkbook = Application.activeWorkbook
Set activeWorksheet = GetTemplateData(activeWorkbook)
activeWorkbook.Save
End Sub
'Get The Template Data
Private Function GetTemplateData(activeWorkbook As Workbook) As Worksheet
Dim templateWorkbook As Workbook
'Grab the Template Worksheet
Set templateWorkbook = UseFileDialogOpen
'Select all Content
Range("A1").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Copy
'activeWorkbook.Sheets(activeWorkbook.Sheets.Count).Range("A1", Cells.End(xlDown) & Cells.End(xlRight)).PasteSpecial xlPasteValues
activeWorkbook.Sheets(1).Range("A1", Cells.End(xlDown) & Cells.End(xlRight)).PasteSpecial xlPasteValues
End Function
'From https://learn.microsoft.com/de-de/office/vba/api/excel.application.filedialog
'Select the Workbook containing the Exported Template-Stories by User Selection
Function UseFileDialogOpen() As Workbook
Dim lngCount As Long
Dim filePath As String
Dim templateBook As Workbook
' Open the file dialog
With Application.FileDialog(msoFileDialogOpen)
.AllowMultiSelect = False
.Show
Set templateBook = Workbooks.Open(.SelectedItems(1))
' Display paths of each file selected
'For lngCount = 1 To .SelectedItems.Count
' MsgBox .SelectedItems(lngCount)
'Next lngCount
End With
templateBook
End Function

Answer 1

I believe all of your problems originate here:
Private Sub GenerateValues()
'Application.ScreenUpdating = False
'Application.DisplayAlerts = False
Dim activeWorkbook As Workbook
Dim activeWorksheet As Worksheet
Set activeWorkbook = Application.activeWorkbook
Set activeWorksheet = GetTemplateData(activeWorkbook)
activeWorkbook.Save
End Sub
ActiveWorkbook is a defined "variable" in VBA, so it is confused as to why you are trying to reassign it. Try using a different variable name instead.
Note: although ActiveWorksheet is not a defined variable in VBA, it is close in name to ActiveSheet, so I would also change that variable name to something different just so to not confuse you when writing future code.

You could try something similar to this:
Sub CopyContentsFromOtherWorkbook()
Dim wb As Workbook
Dim twb As Workbook
filePath = "C:\File.xlsx"
Set wb = Workbooks.Open(filePath)
wb.Sheets(1).Range("A1:Z10000").Copy
Set twb = ThisWorkbook
twb.Sheets(1).Range("C1").PasteSpecial xlPasteValues
wb.Close
twb.Save
End Sub
