Macro open an excel file based on the latest date found in filename

[moltenmagma]

Hi,

I am faced with yet another challenge.

In my directory folder, I may have an excel files saved as

1. Test 10.08.09.xls
2. Test 20.08.09.xls
3. Test 25.08.09.xls

In Worksheet A, I would like to have a button/hyperlink that will open the above excel file that has the latest data. For instance, in this case, the file that needs to be open is Test 25.08.09.xls

Thank you very much in advance

This macro will ask for a starting date and try to open the book with THAT date, failing, it will begin to search backwards from that date until it finds one matching the file name/format you have described. Be sure to edit ThePath.

Sub OpenLatest()
'Opens a sheet based on date entry, searches backward til it finds a matching date
Dim TheString As String, TheDate As Date
Dim ThePath As String, TheBook As Workbook
Set TheBook = ThisWorkbook

ThePath = "C:\Documents and Settings\All Users\Documents\My Documents\Excel Tips\Test\"
TheString = Application.InputBox("Enter starting search date:", Title:="Beginning Search Date")
    
    If IsDate(TheString) Then
        TheDate = DateValue(TheString)
    Else
        MsgBox "Invalid date"
        Exit Sub
    End If
   
TheString = "Test " & WorksheetFunction.Text(TheDate, "DD.MM.YY") & ".xls"

On Error Resume Next
Do
Workbooks.Open ThePath & TheString

    If Err <> 0 Then
        TheDate = TheDate - 1
        TheString = "Test " & WorksheetFunction.Text(TheDate, "DD.MM.YY") & ".xls"
        Err = 0
    Else
        On Error GoTo 0
        Exit Do
    End If
Loop Until ActiveWorkbook.Name <> ThisWorkbook.Name
    
MsgBox "Lastest data found in sheet " & TheString
End Sub

I suppose we could make it just start searching from today's date backward, but your sample seemed to indicate some file dates may be in the future, thought it was best to just let you pick a starting date.
