Unprotecting an Excel Workbook

This was a very cool post.  In case the link goes away, I'm pasting the code here as well.

Create a list of Excel Files in a Worksheet

Here's a code to create a list of Excel files in your worksheet.

This will give me a list of all the Excel files in the folder

C:\Users\Dorothy\Documents\Consulting.

Sub ListExcelFiles()
Const ArrTop As Integer = 300
Dim MyDir As String
Dim FN As String
Dim MyArray(ArrTop) As String
Dim i, j As Integer

On Error Resume Next

MyDir = "\\tsclient\C\Users\Dorothy\Documents\Consulting\"
FN = Dir(MyDir & "\*.xls*", vbDirectory)

i = 1
Do While (Len(FN) > 0) And (i < 101)
  
    If Not (FN = ".") Or (FN = "..") Then
'        MyArray(i) = FN
        Range("a" & i) = FN
        i = i + 1
    End If

    ' Get the next file.
    FN = Dir()
Loop

End Sub

Compacting an Access DB via VBA

This was a great idea that I found on the internet.  It was on tek-tips.com.

Uhh.. toss this little puppy on a command button: Private Sub Command1_Click()    CommandBars("Menu Bar"). _    Controls("Tools"). _    Controls("Database utilities"). _    Controls("Compact and repair database..."). _ accDoDefaultAction End Sub The kicker here is the last line. Note the acCDoDefaultAction. Most other built-in guys use acSomethingOrOther, with only ONE "C" - I don't know if this was a deliberate thing or an acCident.. but this method works for A2K and above.
