Noting When a Workbook was Changed

In an environment where multiple people work on the same workbook, you may want a way to keep track of when people last changed a workbook. There are a couple of ways you can approach this task. One is to simply figure out when a workbook was last saved. This approach works well if you assume that any changes to the workbook are always saved. (Unsaved changes, of course, are not really a lasting change at all.) The following macro returns the date that a workbook was saved and stores that date in cell A1:

Sub DateLastModified()
    Dim fs, f
    Set fs = CreateObject("Scripting.FileSystemObject")
    Set f = fs.GetFile("D:\MyFolder\MyFile.xlsx")
    Cells(1, 1) = f.DateLastModified
End Sub

To use the macro, just replace the D:\MyFolder\MyFile.xlsx file specification with whatever is appropriate for you.

If you want a history sheet of who did what with your workbook, then a different approach is necessary. Perhaps the best solution is to try Excel's sharing feature, which can be configured to keep a history log for a workbook. Follow these steps:

  1. Display the Review tab of the ribbon.
  2. In the Changes group click the Share Workbook tool. Excel displays the Share Workbook dialog box.
  3. Make sure the Editing tab is displayed. (See Figure 1.)
  4. Figure 1. The Editing tab of the Share Workbook dialog box.

  5. Select the Allow Changes check box.
  6. Display the Advanced tab. (See Figure 2.)
  7. Figure 2. The Advanced tab of the Share Workbook dialog box.

  8. Make sure the Keep Change History radio button is selected.
  9. Using the other controls in the dialog box, select the tracking options you want used with the workbook.
  10. Click on OK.
  11. In the Changes group click the Track Changes tool, then choose Highlight Changes from the submenu. Excel displays the Highlight Changes dialog box.
  12. Make sure the List Changes on a New Sheet check box is selected.
  13. Click OK.

As changes are made to the workbook, Excel tracks those changes (along with who made them) and puts them in a separate worksheet so you can review them later.

Another way to figure out when a workbook was last saved is to use Windows.
Open the Start button, choose Computer and drill down into whatever drive & folders house your workbook.

Melanie: When DIM is used without a data type, VBA defaults to declaring the variable as a Variant.

Hi,
I'm fairly new to the world of VBA so please excuse me if this sounds stupid.
I don't understand why "Dim" is used as shown above. It's not really being used to declare the variable type, e.g., "Dim fs as string", so why have it?
I suspect the Dimension statement defaults to something, but what?
Thanks,
Melanie
