Here is some code for you to try. It just fires a message box when the
approprite file has been opened. You can modify it to deal with your data
sheet... If you need help reply back...

Create a blank workbook. In the code window add a class module. Name the
Class module clsXLEvents. Place this code in the class module.

Option Explicit
Private WithEvents xlApp As Excel.Application
Private Const SHEETNAME As String = "Data"
Private Const APPPATH As String = "C:\Test"

Private Sub Class_Initialize()
Set xlApp = Excel.Application
End Sub


Private Sub xlApp_WorkbookOpen(ByVal WB As Workbook)
If SheetExists(SHEETNAME, WB) And WB.Path = APPPATH Then
MsgBox "Tada"
End If
End Sub

Private Function SheetExists(SName As String, _
Optional ByVal WB As Workbook) As Boolean
On Error Resume Next
If WB Is Nothing Then Set WB = ThisWorkbook
SheetExists = CBool(Len(WB.Sheets(SName).Name))
End Function


Now in the thisworkbook module add the following code...
Option Explicit
Dim OpenEvent As clsXLEvents

Private Sub Workbook_AddinInstall()
Set OpenEvent = New clsXLEvents
End Sub

Private Sub Workbook_AddinUninstall()
Set OpenEvent = Nothing
End Sub

Private Sub Workbook_Open()
Set OpenEvent = New clsXLEvents
End Sub

Yea thats exactly what i want it todo. Also I need to put in an "if"
statement for activeworksheet.path so the add-in only formats excel files in
a particular folder. Thanks for your reply....

The code you have is actually a long way from doing what you want to do...
Let me know if this is what you want. Every time that a workbook is opened it
checks for a sheet called Data. If that sheet exists then it reformats that
sheet as per your existing macros?

Just so we are on the same page that can be done but there is no undo after
a macro runs so any sheet called "data" will be reformatted, whether doing so
is appropriate or not.

I have the following code in a module saved as an Add-in. I wanted this
add-in to be activated everytime an excel file is open. When I run this code
while a file is open in the VBA editor, the code works fine. But when I open
a file, the error "Worksheets of object global failed 1004" pops up. I
removed the "Worksheets("data").activate" line to see if it would run but
then the error msg reads "Columns of object global failed 1004". I then
removed the first call hide_cols() and the error msg reads "Cells of object
global failed 1004". I've been searching for clues on the web still cant get
it to work. Any suggestions or help would be greatly apprectiated thanks.
