Writing VBA in Excel 2007 for use in Excel 2003

Question

Where I\'m at the developers have been updated to Excel 2007, but most of the users haven\'t. I\'m building a spreadsheet template (*.xlt) for a user that\'s gonna need som

Answer 1

One difference I discovered is that a subroutine must have a different signature to be called from a menu (in Excel 2003) than when called from the ribbon (in Excel 2007). Whatsmore, Excel 2003 doesn't recognise IRibbonControl and throws compile errors.

To work toward cross-version compatability, I use a Conditional Compilation Argument and then check that in pre-processor macros.

e.g.

#If USINGRIBBON Then
    Public Sub CallFromRibbon(control As IRibbonControl)
#Else
    Public Sub CallFromRibbon()
#End If
    ' Code here
   End Sub

This does mean that you have to save one version of your add-in with the USINGRIBBON flag set to false (for Excel2003) and another with the USINGRIBBON flag set to true (for Excel2007), but this is far easier than maintaining two completely separate codebases.
