To get the current cell in a worksheet, I believe you need to activate it, but you can turn off screen updating so that the user isn't actually aware of the change in focus.
The code below does this, getting the address of the active cell on Sheet 2 of a workbook, outputting this to the debug menu, then moving the cursor on to the next row, before swapping back to the current sheet and turning screens updates:
I hope this helps,
Andrew
Sub MoveToNextCell()
'Turn off screen updates
Application.ScreenUpdating = False
'Get the active cell in worksheet 2
ThisWorkbook.Sheets(2).Activate
'Execute the movement
Debug.Print "Pre-movement address: " & Application.ActiveCell.Address
ThisWorkbook.ActiveSheet.Cells(Application.ActiveCell.Row + 1, Application.ActiveCell.Column).Select
Debug.Print "Post-movement address: " & Application.ActiveCell.Address
'revert back to the original worksheet
ThisWorkbook.Sheets(1).Activate
'Turn screenupdates back on
Application.ScreenUpdating = True
End Sub
