how to resolve vba code with copy from another file - excel

Question

In one file I have data (Zeszyt.xlsm - Sheet1) and in the other an empty file (Sheet2) with the same headers and fill in button. However, when I press the button. There is no mistake but nothing complements. Could you help me ?
Private Sub CommandButton2_Click()
Dim wb As Workbook
ThisWorkbook.Worksheets("Sheet1").Rows(12).Copy
Selection.Copy
Set wb = Workbooks.Open("C:\Users\admin\Desktop\TEST\Zeszyt2.xlsm")
wb.Worksheets("Sheet2").Activate
lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row
ActiveSheet.Cells(lastrow + 1, 1).Select
ActiveSheet.Paste
ActiveWorkbook.Save
ActiveWorkbook.Close savehanges = True
Set wb = Nothing
ThisWorkbook.Worksheets("Sheet1").Activate
ThisWorkbook.Worksheets("Sheet1").Cells(1, 1).Select
Application.CutCopyMode = False
End Sub

Answer 1

There is no need to select or copy/paste.
First of all I would propose to put all parameters like workbook names etc. as constants to the header of the module. By that it is much easier to fix renamings etc.
By having a generic copyRangeValues-routine you can re-use this sub for other copy-actions as well:
Option Explicit
'config source
Private Const wsSourceName As String = "Sheet1"
Private Const rowToCopy As Long = 12 'is this really always row 12????
Private Const wbTargetName As String = "C:\Users\admin\Desktop\TEST\Zeszyt2.xlsm"
Private Const wsTargetName As String = "Sheet2"
Private Sub CommandButton2_Click()
'First step: prepare your source range
Dim wbSource As Workbook
Set wbSource = ThisWorkbook
Dim wsSource As Worksheet
Set wsSource = wbSource.Worksheets(wsSourceName)
Dim rgSource As Range
Set rgSource = wsSource.Rows(rowToCopy)
'second step: prepare your top left target cell
Dim wbTarget As Workbook
Set wbTarget = Workbooks.Open(wbTargetName)
Dim wsTarget As Worksheet
Set wsTarget = wbTarget.Worksheets(wsTargetName)
Dim lastRow As Long
lastRow = wsTarget.UsedRange.Rows.Count
Dim rgTargetCell As Range
Set rgTargetCell = wsTarget.Cells(lastRow + 1, 1)
'third step: copy range - use generic routine
copyRangeValues rgSource, rgTargetCell
'fourth step: close target workbook
wbTarget.Close saveChanges:=True
End Sub
'Put this in a general module
Public Sub copyRangeValues(rgSource As Range, rgTargetCell As Range)
'generic routine to copy one range to another
'rgTargetCell = top left corner of target range
Dim rgTarget As Range
'resize rgTarget according to dimensions of rgSource
With rgSource
Set rgTarget = rgTargetCell.Resize(.Rows.Count, .Columns.Count)
End With
'write values from rgSource to rgTarget - no copy/paste necessary!!!
'formats are not copied - only values
rgTarget.Value = rgSource.Value
End Sub

Copy Row To Another File
The code will run slower if you use Activate and Select. but not if you use variables.
Option Explicit
Private Sub CommandButton2_Click()
Const swsName As String = "Sheet1"
Const sRow As Long = 12
Const dFilePath As String _
= "C:\Users\admin\Desktop\TEST\Zeszyt2.xlsm"
Const dwsName As String = "Sheet2"
Dim swb As Workbook: Set swb = ThisWorkbook
Dim sws As Worksheet: Set sws = swb.Worksheets(swsName)
Dim srg As Range: Set srg = sws.Rows(sRow)
Application.ScreenUpdating = False
Dim dwb As Workbook: Set dwb = Workbooks.Open(dFilePath)
Dim dws As Worksheet: Set dws = dwb.Worksheets(dwsName)
Dim dCell As Range
Set dCell = dws.Cells(dws.Rows.Count, "A").End(xlUp).Offset(1)
srg.Copy Destination:=dCell
dwb.Close SaveChanges:=True
Application.ScreenUpdating = True
MsgBox "Done.", vbInformation, "Append Row"
End Sub
