Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Displaying the "Last Modified" Date.
If you look at the properties stored with a workbook, you will notice that Excel maintains quite a bit of information concerning the file. One of the items is a date and time that is simply noted as "Modified." Many people refer to this as the "last modified" date, but it really reflects the last time the workbook was saved.
If you want to use this date in your workbook (perhaps in a header or footer), you can do so by using the BuiltinDocumentProperties property (that almost sounds redundant). The following macro will add the proper date to the header of your document:
Sub MyHeader1() Dim sLMD As String On Error Resume Next sLMD = ActiveWorkbook.BuiltinDocumentProperties("Last Save Time") If Err = 440 Then Err = 0 sLMD = "Not Set" End If sLMD = Left(sLMD, 8) ActiveSheet.PageSetup.LeftHeader = "Last Saved: " & sLMD End Sub
There are a number of items to note in this macro. First of all, it attempts to determine the last date the workbook was saved. If that information cannot be determined, then it sets the header to "Not Set."
Notice that there is some error handling done in this macro. The reason is that Excel will return an error if a particular document property (BuiltinDocumentProperties in this case) is not set. The error needs to be intercepted and handled, which is done here.
There is another item to note here. In some versions of Excel, the Err value returned if the property is not set is not really 440 (as shown here), but some other odd number, such as -2147467259. This is very bizarre, indeed. Why the 440 value (which is the proper error code) would be returned in one circumstance and not in another, I don't know. (Perhaps some other Excel guru will know the answer.) If you have this problem, there are two approaches you can take. First, you can replace the 440 value with the other value (-2147467259). The second option, assuming you have already saved the workbook at least once, is to use a different macro. The following reads the "last modified" attribute from the file itself and stores that info in the header:
Sub MyHeader2() Dim fs As Variant Dim f As Variant Dim sLMD As String Set fs = CreateObject("Scripting.FileSystemObject") Set f = fs.GetFile(ActiveWorkbook.Path & "\" & _ ActiveWorkbook.Name) sLMD = Left(f.DateLastModified, 8) ActiveSheet.PageSetup.LeftHeader = "Last Modified: " & sLMD End Sub
Regardless of which macro you use, remember that the macro, once run, will set the left header to the desired information. That information will not change again until you run the macro again. Thus, if you always want an up-to-date date in the header, then you should either run the macro periodically (perhaps right before printing) or set it up to run whenever you open your document.
