find out original/previous worksheet name

Hi

I encountered some problem, hope you can help me.
I'm executing some macro by pushing a button in my worksheet.
During the macro I'm activating another sheet in another xsl file and collecting data from it.
at the end I need to go back to my original sheet(where the button located) and activate it to update a chart on this sheet.

how can I recognize the name of the sheet, so I will be able to activate it at the end of the macro? or is there any other way to activate previous sheet?

hope the problem is understandable.

Thanks!

You have not provided the code, so I will use a simple scenario.

2 workbooks "Book1" and "Book2", you want to copy Book1,Sheet1,A1 and paste it to Book2,Sheet1,A1.
With both workbooks open you would use the macro recorder and end up with a code like this, these codes will be in Book2

Sub Macro7()

    Windows("Book1").Activate
    Sheets("Sheet1").Select
    Range("A1").Select
    Selection.Copy
    Windows("Book2").Activate
    Sheets("Sheet1").Select
    Range("A1").Select
    ActiveSheet.Paste
    Application.CutCopyMode = False
End Sub

The following code will do the same thing without having to physically select Book1 to get the data.

Sub GetData1()
    Dim wb1 As Workbook, wb2 As Workbook, _
        ws1 As Worksheet, ws2 As Worksheet, c As Range, p As Range
    Set wb1 = Workbooks("Book1")
    Set wb2 = Workbooks("Book2")
    Set ws1 = wb1.Worksheets("Sheet1")
    Set ws2 = wb2.Worksheets("Sheet1")
    Set c = ws1.Range("A1")
    Set p = ws2.Range("A1")
    
    c.Copy Destination:=p
    
End Sub

This may work as well.

Sub GetData2()
    Workbooks("Book2").Worksheets("Sheet1").Range("A1") = Workbooks("Book1").Worksheets("Sheet1").Range("A1")
End Sub
